What’s happening
The steady loss of species (biodiversity loss) weakens the critical relationships between remaining species, including humans, resulting in declining health and, in some cases, extinction.
Insect populations are declining in many regions¹
Bird populations have dropped significantly over the past decades²
Natural areas continue to be lost or fragmented³
These changes are gradual, but they affect the systems that support life.
Why it matters where you live
Much of the land where we live is no longer supporting the diversity of life it once did.
The U.S. contains an estimated 135 million acres of residential landscape⁴, much of it managed as lawn. These areas provide less food and habitat for insects and other wildlife than native plant communities.
At the same time, natural habitats are being reduced and fragmented. Protected lands play an essential role, but they are not large or connected enough on their own to sustain biodiversity over time.
Protected lands alone cannot sustain biodiversity.
The opportunity
Most land in the United States is privately owned⁵. This means the future of biodiversity depends largely on how land is managed outside of protected areas.
When individuals change how they manage their space, those actions begin to connect. Across many properties, small changes can reconnect habitat and support ecological function at a broader scale.
