Yellowstone National Park - USA
The reintroduction of gray wolves in 1995, after being exterminated in the 1920s, helped control elk populations which led to the recovery of plant communities and riparian ecosystems.
Danube River - Europe
Multi-country collaboration efforts including pollution control, wetland restoration, and sustainable fishing practices, improving water quality and increasing populations of sturgeons, pelicans, and other wildlife.
Community Baboon Sanctuary - Belize
Locally led effort in conserving and managing the black howler monkey habitat. Outcomes included a rise in monkey populations and an ecotourism boost for the local economy.
The Everglades - Florida, USA
Comprehensive Everglades Restoration Plan included building reservoirs and stormwater treatment areas, redirecting water flow, and removing invasive species. Results saw improved water quality and increased populations of native species like the American alligator and the Florida panther.
Loess Plateau - China
Actions included terracing, tree planting, and sustainable agricultural practices. Results were decreased soil erosion, improved soil fertility, and increased incomes for local farmers.
The High Line - New York City, USA
Conversion of an old elevated rail line into a green urban park that has revitalized native plant species in the area and provided a new habitat for urban wildlife.
Galápagos Islands - Ecuador
Eradication of invasive species, particularly goats on Pinta and Santiago islands, to restore native flora and fauna. This led to the natural regeneration of ecosystems and return of endemic species like the Galápagos giant tortoise.
Aral Sea - Central Asia
Projects like the construction of Kokaral Dam to raise water levels in the Northern Aral Sea led to increased fish stocks and improved local climate conditions.
Chesapeake Bay - USA
Efforts to reduce pollution included upgrading wastewater treatment plants, reducing agricultural runoff, and restoring oyster habitats. These actions led to clearer waters and the return of seagrasses and aquatic life.
North Norfolk Saltmarshes - UK
Managed realignment and breaches in sea defenses allowed tidal flooding to restore natural saltmarsh habitat. This increased biodiversity and provided natural coastal defense.
