Delineates outbreaks of the two focal species referred to as Mountain Pine Bettle Covers the CCE and 50km into the surrounding area from 2000 to 2015. This layer is a compilation from multiple sources, Bruce spanworm polygons were removed from Alberta data. This dataset was developed by the Crown Managers Partnership, as part of a transboundary collaborative management initiative for the Crown of the Continent Ecosystem, based on commonly identified management priorities that are relevant at the landscape scale. The CMP is collaborative group of land managers, scientists, and stakeholder in the CCE.

The Rainwater Basin (RWB) wetland complex in south-central Nebraska provides crucial stopover habitat for over 7 million waterfowl and 500,000 shorebirds every spring. However, only 10% of the original RWB wetlands remain, resulting in less available habitat for wetland-dependent birds. Conservation efforts are being employed to alleviate the loss of RWB wetlands. To aid conservation efforts, we created a vegetation map of all historical RWB wetlands based on 2004 imagery. The shapefile maps the 2004 vegetation communities for all historic wetlands in the Rainwater Basin region of Nebraska, USA. Vegetation communities include cropped areas that rarely pond water, cropped areas that often pond water, bare soil...

Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including...

This layer shows aspin defoliators (large aspen torix and forest tent caterpillars) damage in the Crown of the Continent and a 50km buffer. Delineates outbreaks of the two focal species referred to as aspen defoliators (large aspen torix and forest tent caterpillar). Covers the CCE and 50km into the surrounding area from 2000 to 2007. This layer is a compilation from multiple sources, Bruce spanworm polygons were removed from Alberta data, focal species were extracted from USDA data.This dataset was developed by the Crown Managers Partnership, as part of a transboundary collaborative management initiative for the Crown of the Continent Ecosystem, based on commonly identified management priorities that are relevant...

This shapefile maps the 2012 vegetation communities for all historic wetlands in the Rainwater Basin region of Nebraska, USA. Vegetation communities include cropped areas that rarely pond water, cropped areas that often pond water, bare soil or mudflat, standing water, moist soil species, wetmeadow species, grasses, reed canarygrass, river bulrush, cattail, and woody species. Communities are based on training data from 2012 field vegetation surveys of over 12,000 points. This map is an update of a RWB vegetation map created in 2004. These data were processed by Ele Nugent, Roger Grosse, and Andy Bishop with the Rainwater Basin Joint Venture (RWBJV), with help from RWBJV Geographic Information Systems Laboratory...
