- Abstract
Boundary structure can hinder or facilitate disturbance of the boundary vegetation by farming practices, such as herbicide and fertiliser drift and occasional cultivation; this may affect their potential role as a weed reservoir. It would be relevant for researchers, farmers and legislators to know whether relationships exist between boundary structure and weed abundance and frequency in boundaries and adjacent fields. In this study, we present a classification of arable field boundaries based on five descriptors: presence of a bank, width, percentage cover of woody and evergreen perennials (WEP), presence of a stonewall and presence of trees. Five types of boundaries are identified, ranging from structurally simple ones (flat, narrow, dominated by annual species) to structurally complex ones (presence of a bank, more than 3 m wide, dominated by WEP). Data from three Spanish regions were used to validate this classification, and the five boundary classes contained different plant communities. Structurally simple, flat and narrow boundaries contained many of the weed species found also in the field centre and with high abundance. More complex, wider boundaries with a slope and a WEP >60%, had a lower probability of hosting the main weeds present in the field centres. Assessment of weed frequency and abundance gave complementary information. The proposed classification of field boundaries may be easily used by farmers and allows adjustment of field margin management to risks posed by the field boundary, in terms of hosting common weeds of arable crops.

Guía de una de las excursiones científicas organizadas como actividad complementaria en el Congreso "Wetlands Biodiversity and Services: Tools for Socio-Ecological Development (Huesca, Spain. 14-18 September 2014)". 5 Pags.- 5 Figs., wetlands in semiarid regions are striking features of the landscape when they occur in deserts or other drylands where water deficit strongly constrains life. in the semiarid region of monegros, ne spain, about 149 saline wetlands or “saladas” occur in karstic depressions. the area is ~70 km southeast of the city of zaragoza, within the semiarid central ebro basin, ne spain. although the environmental concerns of european Union blocked the irrigation works in monegros for several years, and have enforced the exclusion of some areas from irrigation, the playa-lakes are being affected by the new infrastructures and dumping, land consolidation and intensive plow in non-irrigated lands.

Abstract: Agricultural intensification in Europe during the past 30 years has led to changes in compositional and functional weed structure in agroecosystems as well as increases in the prominence of alien weeds. Irrigation is a major driver of agricultural intensification, particularly in semi‐arid zones of the Mediterranean. In the past few decades, irrigated land has expanded in semi‐arid agricultural lands in northeastern Spain. The goals of this study were to identify long‐term temporal changes in compositional and functional weed communities in annual (i.e. maize crops) and perennial (i.e. orchards) irrigated crops of this area and determine whether these changes differentially affect native and alien plants. Changes in the diversity, composition and functional groups of the weed communities in fruit‐tree orchards and maize crops were assessed using plant surveys in 1989 and 2009. During the studied period, a decrease was recorded in the diversity of native species in the fruit‐tree orchards; this decrease was accompanied by an increase in alien weed diversity and a general homogenisation of species in the weed community. In the maize crops, the diversity values of native and alien plants changed little during 20 years. The identification of functional groups revealed that most of the species whose cover increased in the fruit‐tree orchards were graminoid alien species that perform C4 photosynthesis and disperse seed via water or a combination of vectors. In the maize crops, the identified functional groups did not differ in the proportion of species whose cover changed between 1989 and 2009. Hence, in irrigated orchards the observed changes in the weed community and the prominence of alien species are mediated by the selection of a set of traits that let species to overcome management filters. Similarly, the stability of functional composition of weed communities in maize fields is the result of the selection of species functionally similar to the crop. [ABSTRACT FROM AUTHOR]
