Sensitive Lakeshore Identification
Paul Radomski, Project Manager
This is a cooperative project between Minnesota Counties, non-profit organizations, and the Minnesota DNR. The goal of the project is to identify areas along lakeshores that provide unique or critical ecological habitat and to use multiple approaches to protect those identified lakeshores.
The DNR established objective, science-based criteria to identify sensitive shoreland parcels on large lakes that counties have identified as high priority sites (e.g., Ten Mile, Woman, Leech, and Pelican lakes). These lakes represent some of Minnesota's largest and most valuable waters. These lakes also contain extensive areas of undeveloped shoreland that would benefit from additional protection.
Local and state resource managers will be able to use the information provided by the Sensitive Lakeshore Identification project to help ensure that sensitive habitats are receiving sufficient protection. Local governments can use Minnesota's Alternative Shoreland Management Standards tools to protect water quality. One of the key tools is a process that allows local governments to increase the protection of ecologically sensitive shoreland. Areas that are identified as sensitive, such as sections of shoreline, whole bays, or whole lakes, can be put into a more protective zoning category (e.g., local governments can reclassify to a natural environment class or district). Lakes that would benefit the most with the application of this innovative tool are some of Minnesota's most valuable lakes-large lakes with significant undeveloped shorelands.
In addition, landowners that have property on sensitive lakes or within sensitive lakeshore areas may be willing to donate permanent conservation easements. Using conservation easements is a long-term strategy to protect critical lands and aquatic habitats, recreational opportunities, and water quality. This voluntary approach is more flexible and can be applied to smaller areas (e.g., shoreland parcels with frontage of hundreds to thousands of feet).
Sensitive areas are places that provide unique or critical ecological habitat. These areas along the shore or in near-shore areas of the lake are crucial to the health and well-being of fish, wildlife, and native plants. Many fish and wildlife species, including many species of greatest conservation need, are highly dependent on naturally vegetated shorelines as habitat for feeding, resting, and mating and juvenile life stages. Development and land alteration in the immediate shoreland and on the shoreline may have significant negative impacts on these species.
The sensitive lakeshore protocols used by the DNR consist of three components: field surveys to assess habitat quality and use by high priority animal species, an ecological model that objectively incorporates various field assessments into a sensitivity index, and the compilation and delivery of information on sensitive lakeshores to various land and resource managers.

- Minnesota's Sensitive Lakeshore Identification Manual
This manual provides an introduction to sensitive lakeshores. It is a tool for researchers and managers interested in surveying aquatic vegetation, near-shore fish and frogs, and shoreland birds. It also includes information on ecological models used to delineate sensitive lakeshores.
