Conservation Science and Economics

Defenders' scientists work on the ground and nationally to ensure that the best available science is used to make decisions on wildlife management. Our economists demonstrate the economic benefits of conserving species and habitat.

Global Warming

By taking immediate steps to reduce greenhouse gas emissions, we can address the root cause of global warming. And by embracing conservation measures, we can help polar bears and other affected wildlife adapt to, and navigate through, the looming bottleneck of complex threats posed by climate change.


Conservation Economics

The Conservation Economics Program focuses on objective and transparent economic analysis of the benefits and costs of biodiversity conservation and design of economic incentives for wildlife conservation.


Invasive Species

Invasive species are plants, animals, and microbes that are out of place and out of control. Many are benign and beneficial, providing food, fiber and other benefits. Unfortunately, a small subset become problematic.
