Strategic Land Protection Plan

The Scientific and Natural Areas Strategic Land Protection Plan provides a multi-tiered approach for prioritizing lands to protect through designation as a Scientific & Natural Area (SNA). Secondly it will identify and prioritize areas for conserving biodiversity and rare natural resources.


Primary — Ensure that none of Minnesota's natural heritage is lost from any ecological region of the state.

Secondary — Provide compatible nature-based recreation, education and scientific research opportunities.

SNAs protect

They are established through designation on existing public lands, acquisition, and leasing.

Gap Analysis

A statewide Gap Analysis evaluated which native plant communities in each Ecological Classification System subsection are protected within existing SNAs and a broader conservation networks (including publicly and privately own preserves).

Conservation Prioritization Results

If 10% of these high priority areas become SNAs, the state would be protecting approximately 325,000 acres or 0.6 % of the state. It would also mean designating 136,000 more acres of SNAs over the next 85 years. This might equate to an estimated 300 SNAs by the end of the 21st century.

In the next twenty years, SNA protection would be targeted in each Ecological Classification System province at these percentages:

Conservation Opportunity Areas

At a regional (multi-county) landscape scale, the SNA Strategic Land Protection Plan describes Conservation Opportunity Areas to focus the work of the SNA Program, partners, and others in protecting biodiversity and rare features. These Opportunity Areas range in size from approximately 1,200 acres to 410,000 acres.

Candidate Site Evaluation Guide

At the small parcel scale, the SNA Strategic Land Protection Plan provides Candidate Site Evaluation Guide to rate each candidate site and to make informed decisions about pursuing potential acquisitions and designations. This Guide has been tested and used on numerous potential sites. It is a useful way of sifting out sites that are not priorities as SNAs.

The future of natural areas and rare natural features depends upon conservation across all ownerships. The SNA Program and the DNR look forward to building relationships with individuals and organizations to implement this Strategic Land Protection Plan in conserving the state's natural areas and rare resources.
