Habitat Mapping

 

Hudson River Estuary Habitat Mapping

The Research Reserve has partnered with the Cornell University Institute for Resource Information Systems (IRIS), to interpret aerial photographs for vegetative cover type and to produce several habitat mapping products as GIS layers.

All mapping products are publicly available on the NYS GIS Clearinghouse.

HRNERR Vegetation Sampling

HRNERR Vegetation Sampling

  • Hudson River NERR Vegetation maps documented 20 vegetation categories within the four Reserve component sites in 1991, 1997, and 2005. The objectives in performing this mapping were to document existing plant community composition and distribution and analyze changes in this composition and distribution over time.
Submerged Aquatic Vegetation

Submerged Aquatic Vegetation

  • Hudson River Estuary Submerged Aquatic Vegetation (SAV) maps were generated to document the coverage of native SAV and invasive Trapa natans within the Hudson River Estuary from Troy to Hastings-on-Hudson in 1997, 2002, 2007 and 2014. Objectives addressed in the SAV mapping include assessing 1) current distribution and abundance; 2) status and trends of the habitat; 3) ecosystem function of SAV; 4) major threats and impacts to SAV; and 5) needed regulatory protection. An additional SAV mapping product, the Hudson River Estuary Documented SAV, combines the 1997, 2002, 2007 and 2014 mapping layers to provide a management tool that shows areas where SAV currently exists, where it has existed in the past, and where it may return in the future.  Aerial photography from 2016 is in the process of being interpreted. Check back soon for more updates. 
Tidal Wetland Vegetation

Tidal Wetland Vegetation

  • Hudson River Estuary Tidal Wetlands maps were also produced from the 2007 aerial photo inventory for the Hudson River Estuary from Troy to Hastings-on-Hudson. The tidal wetland mapping objective was to develop an atlas/index of potential impact areas to assist in review of river development plans based on the existing plant community composition and distribution.
