NYNHP Data Available for Download

This page provides GIS and other data developed by the Heritage Program available for download. These are usually derived data (such as spatial models) and are intended for use and analysis by those knowledgeable in Geographic Information Systems (GIS) and spatial analysis. Many of these layers can be viewed online at the Energy and Biodiversity mapping site (http://www.ebd.mapny.info ), the Environmental Resource Mapper (http://www.dec.ny.gov/animals/38801.html ), or New York Nature Explorer (http://www.dec.ny.gov/animals/57844.html ).

Each download consists of a zip file containing a PDF with metadata for the layer and the file(s) associated with the GIS layer itself. The files are provided in two formats, ArcGIS layer package and GeoTiff for rasters and ArcGIS layer package and shapefile for vector datasets. If using ArcMap, use the layer package as that maintains an appropriate color scheme for display. Click on the text indicating the file size to initiate a download.

Data layers are grouped in the following categories to make them easier to find.
Landscape Condition Assessment model
Stacked distribution models
Migratory Bird Stopover Models

Landscape Condition Assessment model

The GIS layer provided in this table was developed as part of our ongoing Wetlands Assessment work.

Layer Description Date Posted ArcGIS lyr pkg Geo-TIFF shp
Landscape Condition Assessment (LCA) model This layer depicts the presumed impacts from a suite of anthropogenic stressors across the landscape of the state. The 13 input stressors include five categories of roads from ALIS, active rail lines, three categories of development intensity and one representation of open spaces from CCAP, electric and natural gas corridors, and cropland from CropScape. A sigmoid decay function was applied to each stressor to model the attenuation of ecological effects away from its footprint. The model synthesizes the results of these 'decay footprints' at the 30 m x 30 m pixel scale – each pixel has a score representing cumulative stress. The effectiveness of the model for estimating wetland quality (Level 1 assessment) has been evaluated with field work at two levels of sampling intensity and shown to be effective. 7 June 2016 523 MB 555 MB

Modeled Migratory Bird Stopovers: Fall Migrants This layer depicts the results for models predicting the fall stopover habitat for 28 species of migratory birds.

Terrestrial Connectivity: Priority Large Forested Areas This layer depicts the matrix forest blocks selected by The Nature Conservancy as the most viable examples of the dominant forest communities throughout the state. Matrix sites are large contiguous areas whose size and natural condition allow for the maintenance of ecological processes, viable occurrences of matrix forest communities, embedded large and small patch communities, and embedded species populations. 15 July 2014 1.1 MB 0.9 MB
Terrestrial Connectivity: Forest Block Linkages and Linkage Zones Linkages: This layer depicts the Least Cost Paths (LCP) among forest blocks; one model of the best way to maintain connectivity for the populations of plants and animals of these forests. A least cost path balances travel distance and ease of travel -- here designated as the amount of natural land within 1 kilometer. The goal is to describe the most permeable part of the landscape between a pair of forest blocks. LCPs may help identify habitat stepping stones, riparian zones, or even wide swaths of natural land and thus should be viewed within the context of the landscape, not simply as a line on the ground. Linkage Zones: This layer depicts the Conditional Minimum Transit Cost linkage zones among forest blocks. A zone between two forest blocks depicts the area around all the paths represented by the cost of the single LCP plus 20%. The goal is to describe the most permeable part of the landscape between a pair of forest blocks. The LCP and the associated linkage zone may help identify habitat stepping stones, riparian zones, or even wide swaths of natural land and thus should be viewed within the context of the landscape. 15 July 2014 0.4 MB 0.3 MB
