Wetland restorations

Disclaimer for wetland restoration areas

These polygons were drawn using aerial photos as basemaps. Therefore, only those projects that were completed prior to the latest aerial photo capture are accurate in shape and area. Generally speaking, the polygons for projects completed in 2006 and 2007 have not been verified on aerial photos.

For FWS projects, the location is initially provided as a point. These points are then buffered out to create five-acre circles. Once new aerial photography is obtained, the circles will be modified to match the correct project boundary. NRCS polygons delineate the property boundary of the Wetland Reserve Project (WRP) area, not the actual restoration site. This means that there could be some small upland areas within the polygon boundary. For DNR projects, the shape and area is a rough estimate based on sketches provided by the project manager. These are edited, if necessary, when new aerial photography becomes available.

Interpreting the identify report

The Project Acreage is the acreage of the polygon, rounded to the nearest tenth of an acre. It will either show "Private Owner" = 1 or "Public Owner" = 1. If it shows the former, then it is privately owned; if it shows the latter, then it is publicly owned.

The Estimated Acreage Amounts of either Enhancement, Reestablishment, or Creation were made during project planning; so the "Project Acreage" is usually more accurate.

The Number of Basins in Project is a clue to how many polygons were drawn for the project. For example, if it says 3, then there should be three polygons in close proximity that will all have the same project information in their identify reports. In cases where there is more than one polygon, the estimated acreage amounts (for Enhancement, Reestablishment, or Creation) are for the entire project, not the individual polygons.

There are five possible wetland community types: wet meadow, emergent, open water, shrubland, or forested. The estimated acreage for each type is listed. Only those that are present in the project area are listed in the identify report.

The following are techniques used in the restoration: ditchplug, ditchfill, scrape, tilebreak, slope recontour, water control structure, dike or berm. If any of these are listed with a 1 next to it, this means that the technique was used. The 1 is not a count, but rather a "yes".

The Contract Expiration Date is derived from the contract signing date and the length of agreement. If it says "none", then either there was no contract signing date given, or the agreement is perpetual, having no expiration date.

Source: The source of the data is threefold: DNR's Wildlife Managers, FWS and NRCS. The data from FWS and NRCS is imported from each of their own databases. DNR's Wildlife Managers fill out paper forms upon completion of their projects and send them in to Central office for data entry.

Date: New data is continually added as new field sheets come in from DNR's Wildlife Managers. The data from FWS and NRCS is imported annually at the end of their fiscal year (October).

Description: These are voluntary wetland restorations, enhancements, rehabilitations and creations conducted by DNR and Federal staff for private landowners. Techniques include scrapes, berms, ditch plugs, tile breaks, etc. The information collected includes location, date of completion, a description of the restoration (area in acres, technique used, and wetland type), and financial information (partners, money, contracts, funding programs, etc).

Restorations are categorized as follows:

  • alteration of existing wetlands
  • new wetlands where former wetlands once existed
  • new wetlands, where wetlands never existed

Status: Please note this dataset is not fully migrated. The dataset will become complete as all ordinances and information are migrated in 2007.
