Monitoring

Monitoring is essential to effective and efficient conservation: we need to know the effects of our actions on wildlife, from the benefits of actions to recover species to the consequences of authorizing harm. Under a law like the U.S. Endangered Species Act (ESA), monitoring may be a formal process that must occur every five years. It may also include compliance monitoring for the thousands of activities that are authorized under the ESA every year and that affect lsited species.

Automated habitat change detection methods using satellite data to improve conservation law implementation.

A significant limitation in biodiversity conservation has been the effective implementation of laws and regulations that protect species habitats from degradation. Flexible, efficient, and effective monitoring and enforcement methods are needed to …

Missing, delayed, and old: The status of ESA recovery plans

Recovery planning is an essential part of implementing the U.S. Endangered Species Act (ESA), but conservationists and government agencies recognize challenges with the current planning process. Using data from all U.S. domestic and transboundary …

Implementation

Conservation only happens when laws, policies, and planning are actually carried out. After the planning stage, we set to work carrying out the actions wildlife need completed for conservation to work. That may be as broad as implementing the Endangered Species Act (ESA) or as focused as building a fence to keep cattle from trampling habitat for Chiricahua leopard frogs. In the Center for Conservation Innovation at Defenders of Wildlife, we work at the intersection of science, technology, and policy to improve how conservation is implemented.

Data contradict common perceptions about a controversial provision of the US Endangered Species Act

Separating myth and reality is essential for evaluating the effectiveness of laws. Section 7 of the US Endangered Species Act (Act) directs federal agencies to help conserve threatened and endangered species, including by consulting with the US Fish …

30 years of satellite data show imperiled species are most vulnerable to habitat loss on private lands

To stem the ongoing loss of biodiversity, there is an urgent need to distinguish effective and ineffective approaches to protecting species and their habitats. Conservation laws may be strong on paper but ineffective in practice, or vary in …

Endangered Species Act Funding

An analysis of the funding needed for the US Fish and Wildlife Service to properly implement the US Endangered Species Act.

Counties of Occurrence of ESA-Listed Species

The U.S. Fish and Wildlife Service provides tables of the counties of occurrence of each ESA-listed species, but they have no single table that compiles all species' data into a single location. We fill that gap with this simple, sortable, and …
