BackgroundTrees are critical components of rural and urban ecosystems throughout the world. While they have adapted to the historic conditions of their native environments, climate change, urbanization, and human-assisted range expansion may test the storm resiliency of many tree species.ObjectiveIn this global multilingual scoping review, we investigate a range of intrinsic (i.e., tree characteristics) and external (i.e., environmental and management) factors which have been used to predict tree failure during tropical cyclones.DesignWe searched online databases and journals in English, Chinese, French, Japanese, Portuguese, and Spanish to find peer-reviewed papers and dissertations. We retained papers that used ground-based methods to study tree damage following a tropical cyclone and conducted a statistical analysis of factors that influence tree resistance to damage. From each paper we extracted details of study methods, and the relationships between damage and predictors.ResultsOur efforts generated 65 peer-reviewed papers and dissertations that met our final criteria for inclusion (i.e., data on the relative proportion of trees failed/intact as assessed no more than a year after the storm event). Of these papers 37 independent variables were assessed to predict tree failure. Research in both urban and rural settings tends to be concentrated in regions frequently impacted by tropical cyclones. Characteristics of species such as wood density have been studied in rural environments and are also relevant predictors for tree failure in urban trees. Environmental characteristics unique to urban settings such as planting areas surrounded by pavement need further research. Several urban studies demonstrate that risk assessment methods can predict tree failure during a storm.ConclusionResults can be used by future storm researchers to identify both predictors may warrant inclusion in their models as well as predictors which have yet to be tested. Results can also inform planning and activities that can mitigate tropical cyclone damage to the urban forest.

Roads impact a disproportionately larger area than the land area that they occupy, often called the road effect zone. This effect extends to wildlife populations. Impacts on federally listed species include habitat loss and fragmentation, road mortality, the barrier effect, and the habituation effect. Per the Endangered Species Act, these impacts must be assessed before roadway impacts occur. This publication provides an overview of the potential impacts to 29 of Florida’s threatened and endangered animal species from roads. Potential mitigation options include road configuration, signage, speed limits, habitat protection, improved technology, wildlife fencing, and wildlife crossing structures. The goal is to educate transportation engineers and planners to allow for sustainable transportation infrastructure growth while protecting, conserving, and ultimately recovering Florida’s threatened and endangered species.

Urban forests provide critical environmental benefits, but the resilience of these socio-ecological systems to stresses like pest and disease outbreaks relies on tree health and diversity. Despite this, low species diversity continues to be a challenge in urban forest management. Using a participatory research approach in central Florida (United States), we selected and tested underutilized native tree species (Celtis laevigata Willd., Ilex vomitoria Aiton, Taxodium ascendens Brongn., Ulmus alata Michx., and Viburnum obovatum Walter) in two urban settings (streetscape and park) in four communities (total n = 200). Our collaborative process was organized into five steps, including a 2-year monitoring period to assess mortality and health through establishment. At the end of the trial, 156 trees survived with annual mortality rates differing by species and plot type. Taxodium ascendens had the highest annual mortality of the five species trialed. Overall, U. alata and V. obovatum showed the greatest potential in central Florida urban settings. Our tree selection process can guide others who want to create forward-thinking and diverse planting lists. Furthermore, this project demonstrates that co-production of knowledge involving members of local municipalities, practitioners, and researchers can be an effective strategy for selecting and testing underutilized tree species.

Urban Tree Canopy (UTC) greatly enhances the livability of cities by reducing urban heat buildup, mitigating stormwater runoff, and filtering airborne particulates, among other ecological services. These benefits, combined with the relative ease of measuring tree cover from aerial imagery, have led many cities to adopt management strategies based on UTC goals. In this study, we conducted canopy analyses for 300 cities in Florida to assess the impacts of development practices, urban forest ordinances, and hurricanes on tree cover. Within the cities sampled, UTC ranged from 5.9 to 68.7% with a median canopy coverage of 32.3% Our results indicate that the peak gust speeds recorded during past hurricanes events were a significant predictor of canopy coverage (P = 0.001) across the sampled cities. As peak gust speeds increased from 152 km/h (i.e., a lower-intensity Category 1 storm) to 225 km/h (lower-intensity Category 4 and the maximum gusts captured in our data), predicted canopy in developed urban areas decreased by 7.7%. Beyond the impacts of hurricanes and tropical storms, we found that historic landcover and two out of eight urban forest ordinances were significant predictors of existing canopy coverage (P-landcover < 0.001; P-tree preservation ordinance = 0.02, P-heritage tree ordinance = 0.03). Results indicate that some local policies and tree protections can potentially impact urban tree canopy, even in the face of rapid development and periodic natural disturbances.

This 2-page fact sheet written by Michael G. Andreu, Caroline A. Hament, David A. Fox, and Robert J. Northrop and published by the UF/IFAS School of Forest Resources and Conservation describes a 2016 ecological assessment of the urban forest in the city of Gainesville, FL. It provides a detailed look into some of the economic and ecological values of the forest to enhance understanding and improve urban forest policies, planning, and management, as well as to provide empirical data for the inclusion of trees within environmental regulations. https://edis.ifas.ufl.edu/fr417

Trees in cities were formerly thought of merely as a collection of individuals found along streets and incorporated into landscaping. However, urban trees are now viewed as being part of a unique forest type, and understanding the urban forest’s structure and composition is an important first step towards managing it. This 4-page fact sheet written by Michael G. Andreu, Caroline A. Hament, David A. Fox, and Robert J. Northrop and published by the UF/IFAS School of Forest Resources and Conservation aims to provide a broader understanding of the urban forest in the city of Gainesville, Florida. http://edis.ifas.ufl.edu/fr413

This 3-page fact sheet written by Byron Love, Michael Andreu, and Chris Demers and published by the UF/IFAS School of Forest Resources and Conservation summarizes a study to determine whether landowners may gain increased economic returns if they mark the first thinning in a southern pine stand. The study found that marking can indeed bring higher revenue at final harvest. The greater number of high-quality and faster-growing trees remaining after a marked thinning is the main reason for immediate and future increases in value. https://edis.ifas.ufl.edu/fr410

Urban landscapes are heterogeneous mosaics that develop via significant land-use and land cover (LULC) change. Current LULC models project future landscape patterns, but generally avoid urban landscapes due to heterogeneity. To project LULC change for an urban landscape, we parameterize an established LULC model (Dyna-CLUE) under baseline conditions (continued current trends) for a sub-tropical urban watershed in Tampa, FL. Change was modeled for 2012–2016 with observed data from 1995–2011. An ecosystem services-centric classification was used to define 9 LULC classes. Dyna-CLUE projects change using two modules: non-spatial quantity and spatial reallocation. The data-intensive spatial module requires a binomial logistic regression of socioecological driving factors, maps of restricted areas, and conversion settings, which control the sensitivity of class-to-class conversions. Observed quantity trends showed a decrease in area for agriculture, rangeland and upland forests by 49%, 56% and 27% respectively with a 22% increase in residential and 8% increase in built areas, primarily during 1995–2004. The spatial module projected future change to occur mostly in the relatively rural northeastern section of the watershed. Receiver-operating characteristic curves to evaluate driving factors averaged an area of 0.73 across classes. The manipulation of these baseline trends as constrained scenarios will not only enable urban planners to project future patterns under many ecological, economic and sociological conditions, but also examine changes in urban ecosystem services.

Australian pine was originally planted in Florida in the late 1800′s as a windbreak and for shade. But soon thereafter it was spreading without help from humans. Today it is considered a category I invasive species in Florida, and the Division of Plant Industry strictly prohibits possessing, transporting, and cultivating this species. For those who find this tree in close proximity to their home, it’s a good idea to replace it since Australian pine is known to have a very low resistance to wind. Australian pine is commonly found growing on coastal shorelines since it thrives in salty, sandy environments. This 2-page fact sheet was written by Michael G. Andreu, Melissa H. Friedman, and Robert J. Northrop, and published by the UF Department of School of Forest Resources and Conservation, July 2012. FOR298/FR366: Casuarina equisetifolia, Australian Pine (ufl.edu)

This poisonous tree is native to southern Florida, the Keys, many of the Caribbean islands, Mexico, and Central America. Though it is poisonous to humans and many animals, iguanas eat the fruit and sometimes live among the tree’s limbs. It’s found along the seacoasts and in brackish swamps where it grows among mangroves. Each leaf has a small gland where the leaf joins the stem. The bark is reddish-to-grayish brown and cracked looking. Flowers inconspicuous, but the spikes or leafless stems that the flowers emerge from are visible. The fruit is bright-green and looks like a small apple. This 2-page fact sheet was written by Michael G. Andreu and Melissa H. Friedman, and published by the UF Department of School of Forest Resources and Conservation, July 2012.

Many people find kumquat trees attractive and useful yard specimens. Their dark green leaves and contrasting bright orange fruits give them ornamental quality, and their relatively small size makes them easy to care for once they’re established. Because kumquats generally require less care than other citrus trees, they may be a good choice for gardeners with less time or experience, but who still desire an attractive and tasty citrus tree. If space is an issue, kumquats also do well in containers as long as they receive proper sunlight and watering. This 2-page fact sheet was written by Michael G. Andreu, Melissa H. Friedman, and Robert J. Northrop, and published by the UF Department of School of Forest Resources and Conservation, July 2012. FOR300/FR368: Fortunella spp., Kumquat (ufl.edu)

This deciduous tree is native to South and Central America and is commonly planted in Florida as an ornamental landscape and shade tree. It has attractive, bright yellow blossoms produced in the absence of leaves. Once established, this tree is drought tolerant, making it easier to care for and less demanding on water resources. Yellow trumpet tree also has a relatively high tolerance to salt spray, and therefore is an appropriate street tree or yard specimen in coastal areas. This 2-page fact sheet was written by Michael G. Andreu, Melissa H. Friedman, and Robert J. Northrop, and published by the UF Department of School of Forest Resources and Conservation, July 2012.

Water locust’s wide, spreading root system and affinity for hydric conditions makes it a useful specimen for erosion control on wet banks of freshwater systems. While not widely available, planting this tree in residential yards or other public locations may be less than ideal, since the long and sharply pointed thorns on the main trunk and branches can be hazardous. This deciduous tree is native to Florida. This 2-page fact sheet was written by Michael G. Andreu, Melissa H. Friedman, and Robert J.

In Florida, white leadtree is a prohibited species and therefore is not used in commercial applications in the state. However, in its native range, it is used as a source of charcoal, fuel, and lumber. It has also been planted as a windbreak for crops such as coffee and cocoa, and some ranchers use the tree as a source of both shade and forage for cattle, with the pods being an excellent source of protein. In addition, as white leadtree forms a well-developed taproot, it has been planted to assist with erosion control. This 2-page fact sheet was written by Michael G. Andreu, Melissa H. Friedman, and Robert J. Northrop, and published by the UF Department of School of Forest Resources and Conservation, July 2012. FOR299/FR367: Leucaena leucocephala, White Leadtree (ufl.edu)

The Kenyan cassia can be used as a showy ornamental tree or shrub, with its dark foliage and bright yellow flowers. Some people find the seed pods to be unattractive and prune the tree after it flowers to prevent pods from developing. This tree tolerates a wide range of soil types and can be used in a garden, park, patio, or streetscape setting. This 2-page fact sheet was written by Michael G. Andreu, Melissa H. Friedman, and Robert J. Northrop, and published by the UF Department of School of Forest Resources and Conservation, July 2012. FOR296/FR364: Cassia afrofistula, Kenyan Cassia (ufl.edu)

The gold medallion tree is planted primarily as a shade tree or as a decorative specimen for the yard or street. Many people like this tree because of its fast growth rate and showy, bright yellow clusters of flowers that bloom in the summer months. This tree loses its leaves for a very short period each year, but leaves are quickly replaced. Pruning the tree to one main leading stem from which major branches are attached can help increase its strength and sturdiness against strong wind events. The golden medallion tree is also naturally pest resistant, and as long as it is grown in areas where the temperature does not drop below freezing, it is an easy tree to care for.

The name “pink shower” comes from the bright pink blossoms that this tree produces. It is sometimes called “stinking tree” because the pulp in its pods has a very strong smell. This 2-page fact sheet was written by Michael G. Andreu, Melissa H. Friedman, and Robert J. Northrop, and published by the UF Department of School of Forest Resources and Conservation, July 2012.

The showy flowers and manageable height of common pear makes it a favorable ornamental landscape tree. Some find the aromatic flowers and sweet edible fruits to be an additional plus; however, a pollinator specimen must be nearby in order for the female tree to produce fruit. Careful consideration should be taken when choosing a planting location, since the soft fruits can be messy if not harvested. This 2-page fact sheet was written by Michael G. Andreu, Melissa H. Friedman, and Robert J. Northrop, and published by the UF Department of School of Forest Resources and Conservation, August 2012.

Native to Australia, this evergreen tree has use as an ornamental tree that produces moderate shade along a street, median, or yard. The unique flowering structure is eye-catching, and it can be pruned for use as a decorative hedge. Its tolerance of many different soil types and droughty conditions makes it easy to care for after it’s been established.
