This dataset includes plant productivity values for spring, summer and fall from 2000-2016. The data are from remote sensing. The MODIS (Moderate-resolution Imaging Spectroradiometer) satellite provides an image of the park every 10 days, which is used to calculate NDVI (Normalized Difference Vegetation Index) values. Plant productivity is estimated from these values for one day each in spring, summer and fall. This measure is important because plant productivity responds to climate change, and changes in this measure may significantly affect habitat and wildlife.
