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.

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.

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.

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

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.
