Welcome to the Great Plains Regional Herbarium Network
The Great Plains Regional Herbarium Network brings together information from herbaria in North Dakota, South Dakota, Nebraska, Kansas, Minnesota, Iowa, Missouri, Oklahoma, and Texas. It offers multiple resources for learning more about the plants of the region whether as a student, researcher, or member of the public. It will take some time to provide access to all the information located in the region's herbaria but the process has started. Keep checking!

The region includes most of the land from east of the Rocky Mountains to the western edge of the eastern forests. The climate is continental with warm summers and cold winters. Precipitation decreases from east to west, and mostly occurs during the growing season. Prolonged periods with reduced precipitation are not unusual. The vegetation generally ranges from short grass prairies in the west to mixed grass and tall grass prairies as one moves eastward. Forest species from the east and west meet in the valley of the Niobrara River in Nebraska and the Black Hills of South Dakota.
Much of the land area in the eastern portion of the region has been cultivated. Large areas of previously uncultivated areas in the western portion are now facing disturbance by mineral or fossil fuel extraction and conversion of grassland to cropland.
