Much has changed in Idaho since the Hagerman Horse and other native species, such as the camel and mastodon, lived and prospered on the then fertile floodplains of the area. Over 20 inches of precipitation a year created a lush environment for the development and survival of a wide variety of animals.
Today the Hagerman area receives less than 10 inches of precipitation. However, due to the Snake River, natural springs, and other water sources, the area is still able to support an incredible diverse species population. The riparian zones of the Hagerman area support habitat that is important for migratory waterfowl and other many other species.
Plant and animal communities have been greatly impacted by man’s activities over time, including livestock grazing, water diversions, road construction, and recreational uses. Despite these difficulties a wide variety of animals still successfully populate the area.

The catastrophic Bonneville Flood thundered through the Hagerman Valley 15,000 years ago leaving behind enormous fields of rounded lava boulders – some as big as cars. They are called ‘melon gravel’ and can still be seen throughout the valley today.
