Carnivore distributions across chaparral habitats exposed to wildfire and rural housing in southern CaliforniaChaparral and coastal sage scrub habitats in southern California support biologically diverse plant and animal communities. However, native plant and animal species within these shrubland systems are increasingly exposed to human-caused wildfires and an expansion of the human–wildland interface. Few data exist to evaluate the effects of fire and anthropogenic pressures on plant and animal communities found in these ...
Fire Management, Managed Relocation, and Land Conservation Options for Long-Lived Obligate Seeding Plants under Global Changes in Climate, Urbanization, and Fire RegimeMost species face multiple anthropogenic disruptions. Few studies have quantified the cumulative influence of multiple threats on species of conservation concern, and far fewer have quantified the potential relative value of multiple conservation interventions in light of these threats. We linked spatial distribution and population viability models to explore conservation interventions under projected climate change, urbanization, and changes in fire ...James Strittholt and Mike White have published a chapter in Making Transparent Environmental Management Decisions: Applications of the Ecosystem Management Decision Support System called Forest Conservation Planning. The Ecosystem Management Decision Support (EMDS) system has been used around the world to support environmental analysis and planning in many different application areas, and it has been applied over a wide range ...
Linking spatially explicit species distribution and population models to plan for the persistence of plant species under global changeConservation managers and policy makers require models that can rank the impacts of multiple, interacting threats on biodiversity so that actions can be prioritized. An integrated modelling framework was used to predict the viability of plant populations for five species in southern California’s Mediterraneantype ecosystem. The framework integrates forecasts of land-use change from an urban growth model with projections ...
Climate change and fire effects on a prairie-woodland ecotone: projecting species range shifts with a dynamic global vegetation modelLarge shifts in species ranges have been predicted under future climate scenarios based primarily on niche-based species distribution models. However, the mechanisms that would cause such shifts are uncertain. Natural and anthropogenic fires have shaped the distributions of many plant species, but their effects have seldom been included in future projections of species ranges. Here, we examine how the combination ...
