Welcome to the Southern Plains Network

The Southern Plains Inventory & Monitoring Network encompasses 11 national park units across the immense grassland landscapes of southeastern Colorado, central Kansas, northeastern New Mexico, most of Oklahoma, and a large swath of Texas.

One of 32 Inventory and Monitoring networks across the country, we gather and analyze information on specific park natural resources—the plants, animals, and ecosystems that can indicate the overall biological health of southern plains parks. The information we collect helps parks make sound, science-based management decisions that help us preserve these special places.
