Wetlands Resource Module

The USFWS-sponsored WESPAK-SE (Wetland Ecosystem Services Protocol for Alaska – southeast) is intended to provide agencies, NGO’s and the development community a consistent tool for rating functions and values of wetland sites for impact analysis, mitigation planning, and conservation.  Please see detailed information about the Protocol at our partner's website at the Southeast Alaska Land Trust.

This associated Wetland Resource Module, hosted by the Southeast Alaska GIS Library, supports generic wetland mapping and information needs that can yield basic input values and parameters for WESPAK-SE.  The module consists of an interactive web map and a collection of GIS datasets and web map services that be accessed through the GIS Library Geoportal.

  • Level I - Complete.
  • Level II - Unfunded. Compositional information or spatial computations at 3 functional scales -- wetland, buffer, and watershed - that are analytical derivatives of existing datasets and/or involve customization of extraction tools, such as percentages of area in each component Cowardin class, wetness index, summary statistics for expanded NWI attributes, proximity to landslide risk and or existing debris flows, glacial proximity, fish occupancy, human population and use statistics, resource ratings from a variety of regional/watershed assessments and proximity to subsistence locations. 
  • Level III - Unfunded. Expanded functionality to include an analysis of "possible wetlands" derived from soil & topographic data where NWI coverage is lacking, tools for extracted data to be inserted directly into a user’s WESPAK-SE spreadsheet for a particular wetland, the ability to upload completed assessments into an archive and the addition of ground-level photography.
