Photo of goat prairie and scenic floodplain backdropConsistent attention and funding for ecological monitoring began in the early nineties with the Prototype Monitoring Program.  The Prairie Cluster Prototype was established in 1994 to design and conduct monitoring in six Midwest parks. The Heartland Network was funded in 2001 in an effort to expand monitoring from a handful of prototype programs to all parks with significant natural resources.  Operations of the Heartland Network and Prairie Cluster Prototype were integrated in 2004.  The network operates according to rules and procedures outlined in a Network Charter.  Park Superintendents comprising the Network’s Board of Directors oversee the program, with input from the Network’s Technical Committee.   

The network also serves as an administrative umbrella for operations of the Central Great Plains Fire Ecology Program and the Heartland Exotic Plant Management Program


Prototype Monitoring

Click to view the Prairie Cluster LTEM Prototype Parks mapA proposal to establish The Prairie Cluster Prototype was selected in 1994 as one of eleven programs dedicated to leading the development of scientifically credible and cost-effective monitoring programs in the National Park Service.  The prototype programs serve as testing grounds for long-term monitoring, emphasizing the development of sound monitoring protocols, attention to data and data quality issues, and regular reporting of results to management. The Prairie Cluster Prototype became operational in 2002 after a successful program review. For more information about Prairie Cluster Prototype read the Program Overview and Conceptual Design.

The prototype park units are Agate Fossil Beds NM (AGFO), Effigy Mounds NM (EFMO), Homestead NM of America (HOME), Pipestone NM (PIPE), Scotts Bluff NM (SCBL), Tallgrass Prairie N. Preserve (TAPR) and Wilson’s Creek NB (WICR).
