4.4 Terrestrial Communities
• Monitor amphibian populations to detect incidence of fungal and viral infections (e.g., iridoviruses, chytridiomycosis). • Investigate Nutria population densities, population growth rates, dispersal range, and extent of property damage from burrowing and herbivory. Research. Research topics that facilitate appropriate conservation actions include habitat use and preferences, reproductive behavior, fecundity, population dynamics and genetics, feeding, competition, and food web dynamics. Increased understanding of life histories and status helps determine the vulnerability of priority species to further imperilment, in addition to identifying possibilities for improved management and conservation. All stud- ies should provide recommendations for mitigation and restoration. Formal descriptions for known or putative undescribed species and investigations aimed at resolving taxo- nomic status are needed. • Research and identify important wildlife crossing areas; evaluate connectivity issues between intact and fragmented habitats used by priority species; work with partners to improve crossing and connectivity. • Focus habitat use studies on bats and small mammals to clarify how small mammals and bats use early succession habitats. • Study the efcacy and practicality of toad tunnels and other wildlife crossings that allow passage under roadways and help maintain connectivity between wetland metapopulations.
• Determine minimum upland bufers required to sustain at-risk amphibian populations.
Management Practices. Management practices that reduce impacts and work synergis- tically with other conservation actions are needed to enhance the resilience of natural resources. Particular needs include preserving biodiversity, protecting native populations and their habitats, and improving degraded habitats. • Maintain and restore connections between habitat blocks, not only to allow adjust- ments in range in response to climate change, but to maintain genetic connectivity, population resilience, and adaptability more generally. • Develop transportation facilities that utilize longer bridges at streams and wetlands to minimize impacts (and thereby reduce mitigation requirements) and provide crossing options for wildlife that often travel riparian corridors. Wildlife underpasses should be constructed for all new highway projects, as these reduce wildlife–vehicle collisions, conserve important travel corridors, and provide linkages for bear populations and many other wildlife species.
