2. Background… • “Parks are part of larger ecological systems and must be managed in that context” (Fancy, Gross, & Carter, 2008). • Worked funded through the USGS/NPS National Park Monitoring Project. Currently just starting year 2 of 3. • 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.

6. 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.

7. 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, veg map, or fire monitoring • Fairly native grassland
