Detection of Species-specific Plant Phenology from PlanetScope Time Series for Rangeland Management of the Western United States

  • The National Aeronautics and Space Administration (NASA),10/01/2023-09/01/2025
  • PI: X. Zhang (SDSU), CoIs: Y. Liu (SDSU), (USGS), (USGS)

This proposal focuses on the detection of species-specific plant phenology from PlanetScope time series for rangeland management in the western United States. Rangelands in the United States (US) accounts for approximately 31% of the total land areas, which occur mostly in the western region. However, due to low vegetation signal-to-noise ratios, sparse vegetation cover with high soil background effects, high spatial heterogeneity in local areas, and irregular growing seasons, the detection of Land Surface Phenology (LSP) has been impeded in arid and semiarid rangelands from moderate or coarse satellite pixels. Thus, it is indeed urgently needed to develop an algorithm to accurately detect species-specific phenology in rangelands. This goal can be reached by leveraging PlanetScope observations at ~3 m pixels, which provide unprecedented opportunities for calculating species-specific phenology.
