1 U.S. Department of the Interior U.S. Geological Survey Using Advanced Satellite Products to Better Understand I&M Data within the Context of the Larger Ecoregion Kevin James, NPS I&M Heartland Network Jeff Morisette, USGS Fort Collins Science Center w/ Colin Talbert, USGS Fort and Pete Ma, NASA Goddard Space Flight Center

2 Background…  “Parks are part of larger ecological systems and must be managed in that context” (Fancy, Gross, & Carter, 2008).  Work funded through the USGS/NPS National Park Monitoring Project. Starting third year of funding.  Primary objective: help park managers use cutting edge moderate- (250m) and high- (30m) resolution remote sensing products to place I&M observations within the context of the larger ecosystem.

3 Background…  The foundation for this work is existing and freely available remote sensing data products:  NASA-funded 250m spatial resolution land surface phenology product for North America  Landsat data available from USGS for free.  These products represent a significant national investment in ecosystem monitoring.

4 Objectives:  Characterize phenology across the Southern Plains, Heartland, and Northern Great Plains Networks from 2000 on.  Building on the remote sensed vegetation indices and available Network data, identify appropriate sampling periods and locations that maximize information content for vegetation vital signs monitoring.  Evaluate the impact of management actions in light of intra- and inter-annual vegetation and climate variability.

5 Initial parks: selection criteria  Proposal focused on three networks: Southern Plains, Northern Great Plains, and Heartland Network  We wanted at least one park per network  Fairly large in spatial extent  Existing data from either I&M or fire monitoring programs  Fairly native grassland

Rocca, J.T. Morisette, C.S. Jarnevich, and N. Benson. 2010. Ensemble habitat mapping of invasive plant species., Risk Analysis, 30(2)224-235.

24 Future work  Develop a standard operating procedure (SOP) for integrating MODIS Phenology Data into the I&M program.  Correlative analysis connecting the I&M data to these remote sensing variables  Analysis of comparing phenology metrics inside and outside the park but with the stratification based on land cover type.
