Description

The Southern Great Plains Crucial Habitat Assessment Tool (SGP CHAT) is a spatial model put together to designate and prioritize areas for Lesser prairie-chicken (LEPC) conservation activities and industry development. As such, it plays a duel role in that it is used to encourage development activities to occur outside of high priority areas as well as monitor activities that occur in each of the categories. In many ways it is the spatial representation of the LEPC Range Wide Plan (RWP). Another purpose of this dataset is to create an online tool usable by conservation managers, industry, and the public that identifies priority habitat, including connecting corridors that can be used in the early stages of development or conservation planning. By providing a common data source, used by all, we help target both conservation and development in areas that provide the greatest overall benefits to LEPC.

The SGP CHAT classifies crucial habitats and important wildlife corridors into five “actionable” categories, following guidelines of the WGA:

 

    • Category 1 : This category is comprised of the focul areas for LEPC conservation. The focal areas were designated by teams in each state that prioritized and identified intact LEPC habitat. The goal in this category is to have 70% of the area within, managed under LEPC conservation plans. They were defined using GIS layers such as landscape integrity models, aerial photos, soil maps, anthropogenic disturbances, landcover and expert opinion.

 

    • Category 2 : This category is comprised of the connectivity zones for LEPC conservaion. The connectivity zones were designated by teams in each state that prioritized and identified intact LEPC habitat. The goal in this category is to have 40% of the area within, managed under LEPC conservation plans. They were defined using GIS layers such as landscape integrity models, aerial photos, soil maps, anthropogenic disturbances, landcover and expert opinion.

 

    • Category 3 : This category is derived from the lek Maxent models. Maxent is short for maximum entropy classifier and is an ecological niche model used for describing available and potential habitat. The model uses base layers such as lek, nests, crp, landcover, abiotic site condition, etc..., in a manner that allows for the results to characterize that habitat on the landscape.

 

    • Category 4 : This category is comprised of the estimated occupied range (EOR) for the LEPC plus 10 miles. The EOR is an expert derived delineation that has 10 miles added to it for range expansion and planning.

 

    • Category 5 : This category is comprised of areas outside of the EOR plus 10 mile region.

 

In addition to the CHAT score, the SGP CHAT also contains a suite of the other data layers including: current and historical LEPC range, land cover, oil/gas well density, vertical structures, and a 1-square mile hexagon summary to provide users contextual information about the surrounding landscape .

The SGP CHAT will be updated on an, at this time, undifined timeline. Every effort will be made to inform stakeholders when future changes will occur and make them aware of the process. It is expected that this version of the SGP CHAT will have a 3-5 year lifetime.
