Real-world rewilding

Case studies

The science of rewilding only means something when it meets the ground. These collections examine real projects in depth: the funding, the species, the setbacks, and what actually worked.

What these are

Each case study collection examines real rewilding projects through a specific lens: funding model, ecosystem type, scale, or approach. We aim for accuracy over optimism. Where projects received public money, we say so; where outcomes are mixed, we report both sides.

Funding & Finance
Rewilding without government funding

Government grants are the dominant funding model for large-scale rewilding, but they're not the only one. These projects were initiated and are primarily sustained through private ownership, community fundraising, carbon markets, or ecotourism income.

Rewilding in cities

From pocket wetlands in London parks to river daylighting in Seoul: urban rewilding projects that have measurably improved biodiversity in densely populated areas.

Beaver reintroduction across Europe

Beavers have been reintroduced to over 25 countries since the 1920s. This collection tracks the projects: what triggered flooding concerns, how communities responded, and which approaches worked.

Marine habitat restoration at scale

Seagrass, oyster reefs, kelp forests, and coral: the projects making the greatest measurable impact on marine biodiversity recovery, and the methods behind them.

Beaver engineering as a nature-based solution

A 2026 study across 16 Swiss streams found that beaver dams significantly boost biodiversity in aquatic and semi-aquatic species -- even in urban and agricultural landscapes where restoration is hardest to achieve.

Plant Genetics
Why genetic diversity matters for native plant restoration

Botanist Matt Olson, Ph.D. of Texas Tech University explains why the genetics inside a native planting matter as much as the species you choose, and what to get right from the start.

Karst & Caves
Caves, karst, and rewilding

Chris Thibodaux has spent 35 years exploring and monitoring the cave systems of Central Texas. He talks about what lives underground, what threatens it, and what rewilding means in karst country.

Wildlife Crossings
The Robert L.B. Tobin Land Bridge

A $23 million wildlife corridor carries animals and walkers over a six-lane San Antonio highway that split a 330-acre park in two. Nearly six years of camera-trap data show coyotes, deer, bobcats, and ringtails using it.

Riparian Restoration
Restoring Mimm's Creek

A community-supported riparian restoration project in Marfa, Texas has transformed a bare stretch of ground above Mimm's Creek into a recovering Chihuahuan Desert arroyo, led by the Judd Foundation and Agave Festival Marfa.

Restoring agave for the Mexican long-nosed bat

In the Trans-Pecos region near Big Bend, agave restoration is helping rebuild a nectar corridor for an endangered migratory bat, one of only two known U.S. roosts left for the species.

Research Reviews
Biodiversity Monitoring
How eDNA compares to conventional survey methods

A systematic review of 398 direct comparison studies found eDNA more sensitive and efficient than conventional biodiversity monitoring -- but it consistently identifies different species communities, not the same ones.
