Background: Extreme wildfires have increased in recent decades, yet the consequences of extreme fire behaviour are not fully comprehended. The study of prescribed burning provides opportunities to advance understanding of some overlooked processes in fire behaviour, such as the role of the release of volatile organic compounds (VOC). Aims: The aim of this study was to assess VOC (α-pinene, β-pinene, and limonene), NH
3 , CO and CO2 emissions during prescribed fires in pine barrens vegetation at the Albany Pine Bush Preserve, USA. Methods: Measurements performed by open-path Fourier transform infra-red spectroscopy (OP-FTIR) quantified VOC concentrations and characterised emissions during four independent prescribed burns. Key results: Combustion products (e.g. CO2 , CO, CH4 ) and VOC exhibited similar emission behaviour during thermal degradation, though VOC concentrations appeared to be independent of the type of biomass burned, unlike those of combustion products; Pinus strobus L. emitted two orders of magnitude higher than Pinus rigida Mill.; VOC and CO are statistically correlated (R2 = 0.84). Conclusions: These results confirmed that OP-FTIR is a feasible approach for gathering qualitative and quantitative information regarding VOC emission during prescribed fires. Implications: Quantification of VOC concentrations during prescribed fires helps characterise its relationships with greenhouse gas emissions (e.g. CO2 and CO) at different burning conditions (e.g. wind, biomass type), which could be incorporated into existing fire behaviour models to enhance their ability to better predict fire propagation. Using Albany Pine Bush Preserve (USA) as a case study, this research reports the potentiality of an open-path Fourier transform methodology to assess the trends of volatile organic compounds emissions during prescribed fires.

- Abstract
Bulk density for shrubs and tree crowns is an important variable, useful for many purposes, namely estimations for biomass and carbon sequestration and potential fire behavior prediction. In the latter case, bulk density is required to predict the rate of spread and intensity of crown fires. However, bulk density information is scarce. The estimation of bulk density is crucial to help choosing proper pyrosilviculture options to decrease fire susceptibility. Due to the similar environmental conditions and fuel characteristics in Portugal and Spain, we modelled bulk density for the most common woody species in all the Iberian Peninsula. We used 10 different shrub type formations and a set of tree species or groups common to both countries. Equations for bulk density, in both forest canopy and understory layers, were fitted as a function of biometric variables commonly used in forest inventories for the selected species. Standardized estimates of bulk density can be associated with data from the National Forest Inventories from Portugal and Spain, to estimate biomass of the forest ecosystems and to evaluate potential fire behavior involving tree canopies and shrubs.

- Abstract
Os incêndios, embora devastadores, são parte essencial na formação da paisagem mediterrânica e de alguns processos ecológicos que aí ocorrem. Dependendo das características do fogo, as propriedades do solo podem alterar-se significativamente. Os efeitos do fogo a longo prazo ainda não são bem compreendidos, principalmente na região mediterrânica e em particular em sistemas florestais de sobreiro. Este estudo teve como objetivo avaliar, a longo prazo e a diferentes profundidades, as características químicas dos solos de sobreirais 16 anos após um incêndio, bem como a sua resiliência a esta perturbação. Este estudo realizou-se na Serra do Caldeirão (Sul de Portugal, Algarve). A amostragem de solos decorreu em 2020 e realizou-se principalmente em Leptossolos e em duas profundidades (0-5cm e 5cm – máxima profundidade) em parcelas ardidas em 2004 (n=25) e não queimadas (n=12). As amostras de solos foram caracterizadas quimicamente. Para a maioria dos parâmetros (excepto P extraível e C orgânico) não se verificaram diferenças significativas entre os dois cenários. As concentrações de P extraível (apenas para a camada superficial) e C orgânico (ambas profundidades) foram significativamente maiores nas parcelas queimadas. Os resultados evidenciam a recuperação natural das características químicas dos solos após o fogo e, consequentemente, uma considerável resiliência desses solos, bem como o papel da vegetação na dinâmica de recuperação do solo., Revista de Ciências Agrárias, Vol. 45 N.º 4 (2022)

Serra do Caldeirão ,Leptosols ,Coark oak forest ,Post fire ,Resillience - Abstract
Wildfires, despite being a major disturbance factor, have also an essential role in shaping the Mediterranean landscape and its ecological processes. Post-fire soil properties can change significantly, depending on fire charactheristics. However, long term fire effects on soil are still not well understood, particulary in the Mediterranean region and in cork oak forest systems. This study aimed to provide a long-term assessment of soil chemical characteristics in cork oak forests 16 years after a wildfire, at different depths, and of soil resillience to wildfire. The study was conducted in 2020 at Serra do Caldeirão (southern Portugal, Algarve), mainly in Leptosols. Soil sampling was carried out at two depths (0–5 cm and 5 cm–to maximum depth) in plots burned in 2004 (n=25) and unburned plots (n=12), which were used as control. Soil samples were chemically anallysed in the laboratory. Similar results were obtained for burned and unburned plots, for most of the parameters. The exceptions were extractable P (0-5 cm depth) and organic C (both depths), which were significantly higher in burned plots. The results show a natural recovery of soil characteristics after wildfire and, consequently, indicate a considerable soil resilience and the important role of vegetation on the dynamics of post-fire soil recovery., Os incêndios, embora devastadores, são parte essencial na formação da paisagem mediterrânica e de alguns processos ecológicos que aí ocorrem. Dependendo das características do fogo, as propriedades do solo podem alterar-se significativamente. Os efeitos do fogo a longo prazo ainda não são bem compreendidos, principalmente na região mediterrânica e em particular em sistemas florestais de sobreiro.

- Abstract
Trabajo presentado en el 9º Congresso Florestal Nacional Portugal, celebrado en Funchal (Portugal) del 10 al 14 de octubre de 2022., Os incêndios florestais são uma das maiores fontes globais de emissão de Gases com Efeito de Estufa (GEE), os quais interferem na entrada de radiação solar, a qualidade do ar e o clima a escalas regionais e globais. Durante um processo de combustão completa, o O2 está presente em quantidade suficiente e o CO2 é um dos GEE que é mais libertado. Pelo contrário, num processo de combustão incompleta, a combustão é muito ineficiente e contribui para a emissão de outros gases como CO, metano e óxido nitroso em maiores quantidades. Este último processo pode ocorrer também devido a condições ambientais, severidade do incêndio, e humidade do combustível, entre outros fatores. Para o presente estudo, o stock de C armazenado na vegetação foi considerado como a principal fonte potencial de GEE a ser libertada devido a incêndios florestais. No âmbito do projeto SUDOE REMAS- Gestão de risco de emissão de gases com efeito de estufa em incêndios florestais (SOE3/P4/E0954), a vulnerabilidade às emissões de GEE por incêndios florestais foi mapeada em quatro áreas de estudo florestais no sul da Europa: Serra do Caldeirão (SC-Portugal), Chelva (CH-Espanha), Guadalajara (GJ- Espanha) e Landes de Gascogne (LG-França). Estas áreas, dominadas por diferentes ecossistemas florestais, apresentam diferentes vulnerabilidades ao fogo e às emissões de GEE. Definiu-se vulnerabilidade como as características do ecossistema florestal que o tornam suscetível a perder C (emissões) devido a incêndios florestais e foi quantificada espacialmente para cada área de estudo com base no produto de três componentes: i) Exposição - probabilidade de uma área para arder (%); ii) Sensibilidade - risco de perda instantânea de C em caso de incêndio (proporção entre 0 e 1); (iii) Resiliência - recuperação do sistema após o incêndio (meses). Para estimar as três componentes da vulnerabilidade utilizaram-se áreas ardidas, mapas de uso e ocupação do solo (COS) e imagens de satélite (Landsat). A exposição foi estimada para cada classe de COS como o produto da sua seletividade ao fogo pela frequência do fogo na área de estudo. A sensibilidade foi estimada com o índice NBR (Normalized Burn Ratio) antes e depois do incêndio para cada classe de COS. A resiliência foi estimada por comparação da diferença de NBR entre área ardida e a área não ardida circundante ao longo do tempo, até esta diferença ser nula. Pósteriormente, os valores de biomassa (e C) em 2020 foram estimados com base nos dados dos inventários florestais recolhidos nas parcelas de campo e extrapolados para toda a área de estudo com recurso a machine learning e utilizando-se a correlação entre biomassa e o índice NBR. Por último, com o produto da vulnerabilidade pelo valor estimado de C obteve-se a perda de C por hectare por ano, para cada área de estudo. A exposição ao fogo variou entre 0,1% (LG) e 2,3% (SC), a sensibilidade entre 0,71% (GJ) e 0,89 (LG), e a resiliência entre os 33 meses (SC) e os 60 meses (LG). Como resultado, a perda de carbono ao longo do tempo nas áreas de estudo selecionadas variou de 530 a 200 kg C.ha.ano-1, sendo mais elevada em CH e mais baixa em LG. Obteve-se também um mapa de vulnerabilidade dos ecossistemas florestais, à perda de carbono por incêndios florestais, por pixel (30 x 30m), com base na biomassa atual estimada. Estes resultados permitem uma atualização contínua e pretendem apoiar a gestão e as políticas florestais, Estudo desenvolvido no âmbito do projeto REMAS-SUDOE “Gestão do risco de emissões de gases com efeito de estufa por incêndios florestais”, financiado pelo Programa INTERREG SUDOE, FEDER (UE), referência REMAS – SOE3/P4/E0954.

Trabajo presentado en el 9º Congresso Florestal Nacional Portugal, celebrado en Funchal (Portugal) del 10 al 14 de Octubre de 2022., O fogo é uma parte essencial na formação da paisagem mediterrânica e de alguns processos ecológicos que aí ocorrem. Dependendo das características do fogo, as características da vegetação e as propriedades do solo podem alterar-se significativamente. Os efeitos do fogo a longo prazo ainda não são bem compreendidos, principalmente na região mediterrânica. O SUDOE, espaço que compreende o Sudoeste da Europa, necessita de florestas saudáveis e funcionais que garantam o fornecimento de bens e serviços para as sociedades rurais. O projeto REMAS-SUDOE, cujos parceiros são a Universidade Politécnica de Valência (UPV, ES), Universidade de Valência (UV-CIDE, ES), Diputación de Valencia (DIVAL, ES), Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA, ES), Município de Loulé (CML, PT), Instituto Superior de Agronomia (ISA/Ulisboa, PT), Ecole Nationale Supérieure des Sciences Agronomiques de Bordeaux Aquitaine (Bordeaux Sciences Agro, FR), e coordenação da AMUFOR - Asociación de Municipios Forestales de la Comunidad Valenciana (ES), visa melhorar a ligação e a eficácia dos planos de prevenção e recuperação de incêndio, incluindo a gestão de risco de emissões de gases com efeito estufa resultantes de incêndios florestais nas regiões do espaço SUDOE, que são as mais vulneráveis aos impactes das alterações climáticas. O projeto tem como objetivo (i) quantificar orisco de emissão de gases com efeito de estufa (GEE) em áreas sujeitas a incêndios florestais; (ii) quantificar e desenvolver cartografia de armazenamento de carbono; (iii) propor medidas de recuperação pós incêndio, com vista à minimização do dano e à aceleração da recuperação dos stocks de carbono; e (iv) contribuir para incluir a gestão do risco de emissões de GEE por incêndios florestais no planeamento nacional, e das regiões SUDOE. As áreas de estudo do projeto estão situadas em Chelva (Comunidade Valenciana, Espanha), Parque Natural do Alto TajoTejo (Guadalajara, Espanha), e em Landes de Gascogne (Aquitânia, França). Em Portugal, a área de estudo é a Serra do Caldeirão no Algarve, onde domina o sobreiral. No âmbito do projeto, a estimativa do risco de emissão de GEE tem sido feita com deteção remota, sistemas de informação geográfica (SIG) e com base em informação recolhida em campo dos stocks de carbono na vegetação e solos, tanto em áreas ardidas como não ardidas, com e sem gestão, para analisar os efeitos do fogo e da gestão na dinâmica do carbono. Os principais resultados apontam para uma perda instantânea de carbono de 0 a 89% após o fogo, sendo mais elevada na área de estudo francesa (dominada por pinheiro-bravo). A perda de carbono no tempo é entre 200 e 530 kg C ha-1 ano-1, sendo maior em Chelva. A recuperação total da capacidade de sequestro de carbono foi avaliada em 3 anos após o fogo na Serra do Caldeirão, sendo a recuperação mais rápida de todas as áreas de estudo, o que mostra uma elevada resiliência das florestas de sobreiro ao fogo. Os resultados preliminares para a Serra do Caldeirão indicam que o stock de carbono na vegetação é de cerca de 16 ton C ha-1 e mostram uma boa recuperação das propriedades físicas e químicas dos solos, 8 e 16 anos após os incêndios. Estes resultados irão permitir identificar as melhores práticas para diminuir o risco de emissão de GEE e para ações de restauro de áreas ardidas., Estudo desenvolvido no âmbito do projeto REMAS-SUDOE “Gestão do risco de emissões de gases com efeito de estufa por incêndios florestais”, financiado pelo Programa INTERREG SUDOE, FEDER (UE), referência REMAS – SOE3/P4/E0954.

- Abstract
Wood resources have been essential for human welfare throughout history. Also nowadays, the volume of growing stock (GS) is considered one of the most important forest attributes monitored by National Forest Inventories (NFIs) to inform policy decisions and forest management planning. The origins of forest inventories closely relate to times of early wood shortage in Europe causing the need to explore and plan the utilisation of GS in the catchment areas of mines, saltworks and settlements. Over time, forest surveys became more detailed and their scope turned to larger areas, although they were still conceived as stand-wise inventories. In the 1920s, the first sample-based NFIs were introduced in the northern European countries. Since the earliest beginnings, GS monitoring approaches have considerably evolved. Current NFI methods differ due to country-specific conditions, inventory traditions, and information needs. Consequently, GS estimates were lacking international comparability and were therefore subject to recent harmonisation efforts to meet the increasing demand for consistent forest resource information at European level. As primary large-area monitoring programmes in most European countries, NFIs assess a multitude of variables, describing various aspects of sustainable forest management, including for example wood supply, carbon sequestration, and biodiversity. Many of these contemporary subject matters involve considerations about GS and its changes, at different geographic levels and time frames from past to future developments according to scenario simulations. Due to its historical, continued and currently increasing importance, we provide an up-to-date review focussing on large-area GS monitoring where we i) describe the origins and historical development of European NFIs, ii) address the terminology and present GS definitions of NFIs, iii) summarise the current methods of 23 European NFIs including sampling methods, tree measurements, volume models

- Abstract
O fogo é uma parte essencial na formação da paisagem mediterrânica e de alguns processos ecológicos que aí ocorrem. Dependendo das características do fogo, as características da vegetação e as propriedades do solo podem alterar-se significativamente. Os efeitos do fogo a longo prazo ainda não são bem compreendidos, principalmente na região mediterrânica. O SUDOE, espaço que compreende o Sudoeste da Europa, necessita de florestas saudáveis e funcionais que garantam o fornecimento de bens e serviços para as sociedades rurais. O projeto REMAS-SUDOE, cujos parceiros são a Universidade Politécnica de Valência (UPV, ES), Universidade de Valência (UV-CIDE, ES), Diputación de Valencia (DIVAL, ES), Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA, ES), Município de Loulé (CML, PT), Instituto Superior de Agronomia (ISA/Ulisboa, PT), Ecole Nationale Supérieure des Sciences Agronomiques de Bordeaux Aquitaine (Bordeaux Sciences Agro, FR), e coordenação da AMUFOR - Asociación de Municipios Forestales de la Comunidad Valenciana (ES), visa melhorar a ligação e a eficácia dos planos de prevenção e recuperação de incêndio, incluindo a gestão de risco de emissões de gases com efeito estufa resultantes de incêndios florestais nas regiões do espaço SUDOE, que são as mais vulneráveis aos impactes das alterações climáticas. O projeto tem como objetivo (i) quantificar orisco de emissão de gases com efeito de estufa (GEE) em áreas sujeitas a incêndios florestais; (ii) quantificar e desenvolver cartografia de armazenamento de carbono; (iii) propor medidas de recuperação pós incêndio, com vista à minimização do dano e à aceleração da recuperação dos stocks de carbono; e (iv) contribuir para incluir a gestão do risco de emissões de GEE por incêndios florestais no planeamento nacional, e das regiões SUDOE. As áreas de estudo do projeto estão situadas em Chelva (Comunidade Valenciana, Espanha), Parque Natural do Alto TajoTejo (Guadalajara, Espanha), e em Landes de Gas

- Abstract
Wood resources have been essential for human welfare throughout history. Also nowadays, the volume of growing stock (GS) is considered one of the most important forest attributes monitored by National Forest Inventories (NFIs) to inform policy decisions and forest management planning. The origins of forest inventories closely relate to times of early wood shortage in Europe causing the need to explore and plan the utilisation of GS in the catchment areas of mines, saltworks and settlements. Over time, forest surveys became more detailed and their scope turned to larger areas, although they were still conceived as stand-wise inventories. In the 1920s, the first sample-based NFIs were introduced in the northern European countries. Since the earliest beginnings, GS monitoring approaches have considerably evolved. Current NFI methods differ due to country-specific conditions, inventory traditions, and information needs. Consequently, GS estimates were lacking international comparability and were therefore subject to recent harmonisation efforts to meet the increasing demand for consistent forest resource information at European level. As primary large-area monitoring programmes in most European countries, NFIs assess a multitude of variables, describing various aspects of sustainable forest management, including for example wood supply, carbon sequestration, and biodiversity. Many of these contemporary subject matters involve considerations about GS and its changes, at different geographic levels and time frames from past to future developments according to scenario simulations. Due to its historical, continued and currently increasing importance, we provide an up-to-date review focussing on large-area GS monitoring where we i) describe the origins and historical development of European NFIs, ii) address the terminology and present GS definitions of NFIs, iii) summarise the current methods of 23 European NFIs including sampling methods, tree measurements, volume mode

- Abstract
The quantification of forests available for wood supply (FAWS) is essential for decision-making with regard to the maintenance and enhancement of forest resources and their contribution to the global carbon cycle. The provision of harmonized forest statistics is necessary for the development of forest associated policies and to support decision-making. Based on the National Forest Inventory (NFI) data from 13 European countries, we quantify and compare the areas and aboveground dry biomass (AGB) of FAWS and forest not available for wood supply (FNAWS) according to national and reference definitions by determining the restrictions and associated thresholds considered at country level to classify forests as FAWS or FNAWS. FAWS represent between 75 and 95 % of forest area and AGB for most of the countries in this study. Economic restrictions are the main factor limiting the availability of forests for wood supply, accounting for 67 % of the total FNAWS area and 56 % of the total FNAWS AGB, followed by environmental restrictions. Profitability, slope and accessibility as economic restrictions, and protected areas as environmental restrictions are the factors most frequently considered to distinguish between FAWS and FNAWS. With respect to the area of FNAWS associated with each type of restriction, an overlap among the restrictions of 13.7 % was identified. For most countries, the differences in the FNAWS areas and AGB estimates between national and reference definitions ranged from 0 to 5 %. These results highlight the applicability and reliability of a FAWS reference definition for most of the European countries studied, thereby facilitating a consistent approach to assess forests available for supply for the purpose of international reporting.

- Abstract
National Forest Inventories (NFIs) collect and provide a large amount of information regarding the forest volume, carbon stocks, vitality, biodiversity, non-wood forest products and their changes. Forest stands variables data are paramount to understanding their composition, especially on those related with understory characteristics and the coverage of species according to canopy layers; they are essential to assess biodiversity and to support forest management. At the same time, these inventories allow the development of harmonized forest descriptions beyond the national scale. This study aims to develop a homogeneous characterization of the Iberian Peninsula’s forests, in order to classify and identify the forest types. For this purpose, harmonized data from NFIs of Portugal and Spain were used to assess the composition of species, dominance and the percentage of cover for each species in a vertical space defined by seven canopy layers. Using the “K-means” clustering algorithm, a set of clusters was identified and georeferenced using forest polygons from land use and cover maps of both countries. The interpretation and description of the clusters lead to the establishment of 28 forest types that characterize all of the Iberian Peninsula forests. Each forest area has been described through one of the forest types and their relation with other ecological characteristics of the stands was analyzed. Shrubs formations are generally widely distributed in the forest area of the Iberian Peninsula, however their abundance in terms of cover is lower in comparison with tree species. Around 71% of the forest types are dominated by trees, mainly species from the genera Pinus and Quercus, and 21% are dominated by shrub formations with species of Ulex spp., Cytisus spp., and Cistus spp. The Quercus ilex s.l. L. and Pinus pinaster Aiton are the common species of importance for both NFIs. The results represent a powerful and homogenous multi-use tool describing the Iberian Penins

Forest certification is a voluntary conservation tool that aims to promote sustainable forest management. While research on forest certification has increased recently, there remains a significant gap in understanding how and to what extent certification can promote forest conservation. Mediterranean cork oak open woodlands are ecosystems of high conservation and socio-economic value. However, these ecosystems are threatened by increased adult oak mortality and regeneration failure, often due to inadequate management and the rise of pests and diseases, aggravated by climate change. Forest certification prescribes management practices intended to enhance tree regeneration and maintain stand health conditions. Therefore, it is anticipated that forest certification could mitigate the observed decline of oak trees in Mediterranean regions. Here, we investigate whether forest certification contributes to the ecological sustainability of Mediterranean cork oak open woodlands in Portugal. We compare the stand biometrics of non-certified and certified cork oak stands before and after certification implementation, using both National Forest Inventory data and field sampling from 2005 and 2020. Our findings indicate that the density of adult oak trees decreased by 16 % in certified estates and 28 % in non-certified estates between 2005 and 2020. Similarly, cork oak cover declined by 6 % tree cover in certified plots and 19 % in non-certified plots during the same period. Consequently, by 2020, tree density was 20 % higher in certified stands than in the non-certified ones, and tree cover was 36 % higher in certified stands. Tree diameter and height increased at similar rates in both certified and non-certified stands from 2005 to 2020.The age structure of the stands also remained consistent, showing a bell-shaped distribution of tree diameters in both years. However, results on oak regeneration were inconclusive. Our results suggest that cork oak decline, measured by the changes in density and cover of adult trees from 2005 to 2020, is slower in certified cork oak woodlands. Nonetheless, the increase in tree diameter and the age structure shape indicate potential regeneration issues in both certified and non-certified stands, needing further measures to address the aging of cork oak open woodlands. • Cork oak tree density decreased between 2005 and 2020 throughout the study area. • The decrease in cork oak density was greater in non-certified stands than in certified stands. • In 2020, certified cork oak stands had a higher tree density and cover. • Certification is contributing to mitigating the decline of cork oak woodlands.

- Abstract
Weeds, often seen as a barrier to obtain a high agricultural production, can be part of and contribute to the agricultural ecosystem balance. The aim of the study was to make a flora inventory in natural cover crops of three agricultural ecosystems - olive grove, vineyard and apple orchard - located at Quinta da Alagoa, Ranhados, Viseu. Between 2007 and 2015, from September to December, weeds were monitored using the transect method. In each inventory, the observer moves randomly along a 300 steps transect across the field and records the species present at each step. This study includes the flora inventory, the description of each one and a data analysis by ecosystem and based on biodiversity indexes. This information may help to know and understand the flora biodiversity found in different ecosystems with natural cover crops. A total of 18265 plants were observed belonging to 24 families, 64 genera and 80 taxa. The Asteraceae family showed the greatest diversity of taxa (26,4%). The apple orchard was the ecosystem with higher diversity., As infestantes, vistas na grande maioria das vezes como um obstáculo à boa produção agrícola, traduzem, pela sua presença e dinâmica, uma imensa riqueza que pode ser analisada do ponto de vista do equilíbrio de um ecossistema agrário. Pretendeu-se com este trabalho efetuar a inventariação das espécies de flora presentes em cobertura natural do solo, em três ecossistemas agrários - olival, vinha e pomar de macieiras - localizados na quinta da Alagoa, Ranhados, Viseu. Os inventários foram realizados ao longo de 9 anos, entre 2007 e 2015, mensalmente entre setembro e dezembro, com recurso ao método dos transetos. Em cada inventário, percorreu-se o campo aleatoriamente, perfazendo 300 passos e a cada passo registou-se a espécie presente. Este trabalho, que incluiu os levantamentos florísticos realizados sistematicamente no período de tempo referido, a descrição das espécies encontradas, a análise dos dados por ecossistema e o resultado da aplicação de diversos índices de biodiversidade, permitiu contribuir para a caraterização e compreensão da biodiversidade da flora associada a diferentes ecossistemas com enrelvamento natural. No total observaram-se 18265 plantas pertencentes a 24 famílias, 64 géneros e 80 taxa, sendo que a família com maior diversidade de taxa foi a Asteraceae (26,4%). O pomar foi o ecossistema onde se registou maior diversidade da flora.

- Abstract
The baixa do rio Seia has a large floristic diversity organized in several natural and semi-natural habitats. It is possible to find, in this area, the presence of potential vegetation though it has been the target of intense human interventions, as well as some species that are important in terms of conservation. The main objective of this study was to contribute to the conservation of the local habitats and species, in a area recently detached from the Parque Natural da Serra da Estrela – the baixa do rio Seia. For that, the baixa do rio Seia georeferencing was performed and a floristic survey of the habitats in the area of study (oaks, dry meadows, humid meadows, low forests of heather, forests of lavender, high forest thickets and riparian gallery) was undertaken. About 210taxawere identified belonging to 55 families. Thesetaxarepresent about 40% of the species present in the municipality of Seia. In the area of study, it should be highlighted the presence of a nucleus ofVeronica micrantha Hoffmanns. et Link, the presence ofNarcissus bulbocodiumL., and some species with limited distribution in Portugal, such asMyosotis persooniiandCucubalus bacciferL., A baixa do rio Seia alberga uma grande diversidade florística que se organiza em diversos habitats naturais e seminaturais.

As infestantes, vistas na grande maioria das vezes como um obstáculo à boa produção agrícola, traduzem, pela sua presença e dinâmica, uma imensa riqueza que pode ser analisada do ponto de vista do equilíbrio de um ecossistema agrário. Pretendeu-se com este trabalho efetuar a inventariação das espécies de flora presentes em cobertura natural do solo, em três ecossistemas agrários - olival, vinha e pomar de macieiras - localizados na quinta da Alagoa, Ranhados, Viseu. Os inventários foram realizados ao longo de 9 anos, entre 2007 e 2015, mensalmente entre setembro e dezembro, com recurso ao método dos transetos. Em cada inventário, percorreu-se o campo aleatoriamente, perfazendo 300 passos e a cada passo registou-se a espécie presente. Este trabalho, que incluiu os levantamentos florísticos realizados sistematicamente no período de tempo referido, a descrição das espécies encontradas, a análise dos dados por ecossistema e o resultado da aplicação de diversos índices de biodiversidade, permitiu contribuir para a caraterização e compreensão da biodiversidade da flora associada a diferentes ecossistemas com enrelvamento natural. No total observaram-se 18265 plantas pertencentes a 24 famílias, 64 géneros e 80 taxa, sendo que a família com maior diversidade de taxa foi a Asteraceae (26,4%). O pomar foi o ecossistema onde se registou maior diversidade da flora., Revista de Ciências Agrárias, vol. 40 n.º spe (2017)

- Abstract
Currently there is no internationally accepted framework for assessing the readiness of innovations that reduce disaster risk. To fill this gap, BRIGAID is developing a standard, comprehensive Testing and Implementation Framework (TIF). The TIF is designed to provide innovators with a framework for innovation and guidelines for assessing an innovation’s technical effectiveness, its social acceptance, and its impact on key socio-economic and environmental sectors. The vision is that the TIF will become the standard framework used to assess the effectiveness of climate adaptation innovations and the European quality label for testing.

Studies about the productivity of forest ecosystems help to quantify sequestered carbon and provide data that are used in forest management. Forests in northern Portugal are an important economic resource, but their productivity in scenarios of future climate change is not yet well understood. The objectives of this study were to evaluate and compare simulated net primary production (NPP) and NPP based on measured data of two tree species located in the Vila Real district forests, pine (Pinus pinaster Aiton) and oak (Quercus pyrenaica Willd.) and assess their simulated NPP in diverse climate conditions, including future climate scenarios and increasing atmospheric CO
2 concentrations. An ecosystem process model, Biome-BGC, which simulates carbon, nitrogen and water cycles of forest ecosystems close to equilibrium conditions, was used to examine the importance of site and ecophysiological factors on the productivity of these forests. Climate change scenarios and increased CO2 concentrations were tested to explore potential responses of the studied species. The model provided good estimates of NPP. There was a strong correlation between the simulated and measured NPP values in the pine (15) and oak (15) stands. The NPP of these forests are predicted to increase in the future with a CO2 increase whereas in a climate with higher temperature and lower soil moisture, the NPP will decrease. These results confirm that precipitation is a very important climate variable to growth and productivity in the Mediterranean forest ecosystems. This study also demonstrated the ability of Biome-BGC to accurately simulate forest ecosystems behaviour and encourages the application of model simulations in Portugal.

27 Pág. This article belongs to the Section Forest Ecology and Management., Bulk density for shrubs and tree crowns is an important variable, useful for many purposes, namely estimations for biomass and carbon sequestration and potential fire behavior prediction. In the latter case, bulk density is required to predict the rate of spread and intensity of crown fires. However, bulk density information is scarce. The estimation of bulk density is crucial to help choosing proper pyrosilviculture options to decrease fire susceptibility. Due to the similar environmental conditions and fuel characteristics in Portugal and Spain, we modelled bulk density for the most common woody species in all the Iberian Peninsula. We used 10 different shrub type formations and a set of tree species or groups common to both countries. Equations for bulk density, in both forest canopy and understory layers, were fitted as a function of biometric variables commonly used in forest inventories for the selected species. Standardized estimates of bulk density can be associated with data from the National Forest Inventories from Portugal and Spain, to estimate biomass of the forest ecosystems and to evaluate potential fire behavior involving tree canopies and shrubs., This research was funded from the European Union’s Horizon 2020 research and innovation programme, DIABOLO project “Distributed, integrated and harmonized forest information for bioeconomy outlooks”, EU Grant Agreement no. 633464, and from the EXTREME project “Influence of VOCs (volatile organic compounds) on the extreme behavior of forest fires” (PCIF/GFC/0078/2018), Foundation for Science and Technology.

14 Pág., The quantification of forests available for wood supply (FAWS) is essential for decision-making with regard to the maintenance and enhancement of forest resources and their contribution to the global carbon cycle. The provision of harmonized forest statistics is necessary for the development of forest associated policies and to support decision-making. Based on the National Forest Inventory (NFI) data from 13 European countries, we quantify and compare the areas and aboveground dry biomass (AGB) of FAWS and forest not available for wood supply (FNAWS) according to national and reference definitions by determining the restrictions and associated thresholds considered at country level to classify forests as FAWS or FNAWS. FAWS represent between 75 and 95 % of forest area and AGB for most of the countries in this study. Economic restrictions are the main factor limiting the availability of forests for wood supply, accounting for 67 % of the total FNAWS area and 56 % of the total FNAWS AGB, followed by environmental restrictions. Profitability, slope and accessibility as economic restrictions, and protected areas as environmental restrictions are the factors most frequently considered to distinguish between FAWS and FNAWS. With respect to the area of FNAWS associated with each type of restriction, an overlap among the restrictions of 13.7 % was identified. For most countries, the differences in the FNAWS areas and AGB estimates between national and reference definitions ranged from 0 to 5 %. These results highlight the applicability and reliability of a FAWS reference definition for most of the European countries studied, thereby facilitating a consistent approach to assess forests available for supply for the purpose of international reporting., This research was supported by the Specific contract n. 18 “Use of National Forest Inventories data to estimate area and above ground biomass in European forests not available for wood supply” in the context of the Framework contract for the provision of forest data and services supporting the European Forest Data Centre 2012/ S 78-127532 of 21/04/2012 of the Joint Research Centre of the European Commission; the EG-013-72 agreement of the Ministry of Agriculture, Fisheries and Food (MAPA) and the INIA belonging to the Spanish Ministry of Science and Innovation (MICINN); and the project No.APVV-15-0265 granted by the Slovak Research and Development Agency.
