Restoration Biology

Revitalize functional ecosystems by restoring species
to the wild

• Develop and optimize release programs, including critical evaluation of sites, candidates, and strategies through multidisciplinary collaborations

For some species, reintroduction has meant the difference between survival and extinction. Most importantly, restoration of native species to their natural environments can revitalize healthy, intact ecosystems. CRES is a recognized leader in the application of science-based approaches to reintroduction biology. We are uniquely qualified to foster a comprehensive multidisciplinary approach that combines population genetic management, health assessment, and intensive behavioral, physiological, and ecological research in order to enhance success. Our leadership role is evident in endangered species recovery programs for black rhinos, Pacific pocket mice, California condors, Hawaiian forest birds, San Clemente Island loggerhead shrikes, Caribbean rock iguanas, and tuataras.

• Apply technological advancements to improve post-release monitoring of reintroduced and translocated populations

Previous efforts to understand the fate of released animals have been constrained by our ability to locate and monitor them. CRES scientists develop and apply the latest technologies to track post-release success and guide intervention if necessary. From GPS satellite tracking of California condors and koalas to miniaturized telemetry developed specifically for tiny pocket mice, the data we obtain provide critical feedback to ensure that long-term genetic and demographic goals are met and allow us to improve the design of future reintroduction and translocation efforts.

• Improve methods for managing the impacts of invasive species and restoring disturbed habitats

Invasive species are second only to habitat loss as a cause of extinction. Through its growing plant conservation program, CRES is working to develop new methods for controlling invasive species and protecting native plants from their negative impacts. At the same time, we have launched a research program centered on plant germination requirements, propagation techniques, and use of non-invasive radiography to assess seed viability in support of habitat restoration efforts.

• Expand the spectrum of species and geographic regions for which the Zoological Society has restoration expertise and experience

In addition to continuing our highly successful work with mammals, birds, and reptiles, we plan to expand the spectrum of biodiversity we are able to address through our reintroduction programs to include amphibians and butterflies. With this enhanced global focus will come an unparalleled base of expertise and experience that will put us in an ideal position to respond on an holistic ecosystem level when future crises arise.
