Title Minnesota Restorable Wetland Decision Support - Habitat Stress
Abstract The Habitat Stress decision layer is a single component within a larger suite consisting of six layers. This layer is an index of anthropogenic stress across the landscape with regard to habitat. The Index is a grid (30 meter resolution) that was developed using the following GIS inputs.

- 2011 National Land Cover Dataset (2011 NLCD)
- 2010 Census Population Block densities.
- 2013 Minnesota Pollution Control Agency Feedlot data
- EBI Soil Erosion Risk
- EBI Water Quality Risk

The inputs were combined into a single Habitat Stress grid through an expert panel weighting process. The influence of the surrounding landscape was also addressed. The relative influence of the different anthropogenic land covers were weighted for the following landscape positions:

Immediate influences
The immediate land characteristics at the restoration site can influence a wetland restoration at many different levels including the feasibility of constructing the wetland (i.e. some level of urban development), the initial stress at the site (cultivated crops or high-intensity development, population density, etc), the long term viability of the wetland (hydric soil classification, ownership, topography), and the potential benefits resulting from restoration (habitat potential or water quality risk).

Direct distances
The direct distance to certain land covers can also impact wetlands. For instance, roads can impact water quality through runoff and erosion and habitat through wildlife mortality. Alternatively, nearby wetlands can influence water quality and habitat through hydrologic connectivity. Biodiversity can also be influenced through seed dispersal and population migration.

Focal density
Along with the immediate surroundings, the larger neighboring area can also play a role in defining the ultimate characteristics of a restored wetland. Higher densities of developed or agricultural land covers can influence water quality and habitat. Higher densities of public ownership might reduce the likelihood of current natural upland and wetland areas from being developed.

Upstream influences
Restorable wetland locations are also influenced by their upstream areas including both the amount of upstream area and the types of upstream land covers.

Funding
The development of this data was supported through the Clean Water, Land and Legacy Amendment.
Purpose The Habitat Stress decision layer was developed with the purpose of predicting anthropogenic stress across the landscape with regards to habitat. The decision layer predicts stress levels across the entire Minnesota extent.
