Where We Work

The PPJV covers one-third of North America’s Prairie Pothole Region (PPR), including portions of Montana, North Dakota, South Dakota, Minnesota, and Iowa. Just 20% of the grassland in the PPR is protected, which equates to only 6% of the historic extent of grassland area.

Grassland Bird Habitat Conservation
The PPJV hosts 45-90% of the continental breeding populations for several grassland bird species that are experiencing some of the steepest population declines. The loss of over 70 million acres of grasslands in the PPJV has made grassland birds one of the most imperiled guilds in North America.
Our Amazing Grasslands
South Dakota was once 96% native prairie. Today, much of that is gone. With that loss has come declining bird populations, disappearing pollinators, altered water cycles, and reduced biodiversity. But this isn’t just a story about what we’ve lost. It’s about what remains. Native prairie is resilient — built to withstand drought, fire, and grazing. It protects water, supports wildlife, stores carbon, and sustains both livestock and communities. There is still so much worth saving.
