The Scientific and Natural Areas Program preserves Minnesota's natural heritage (ecological and geological diversity maintained for present and future generations) for scientific study and public understanding. This natural heritage consists of:
The SNA Program preserves both public and private lands.
We work with partners to establish preserves across Minnesota's landscape. Protection of multiple sites in each landscape region is a vital means of capturing the genetic diversity and preventing the loss of communities, species, and features. This strategy observes the wisdom of not putting all of our eggs in one basket.
In the mid-1960s concerned citizens urged Minnesota to become one of the first states to create state owned and managed Natural Areas. In 1965, a 15-member panel of experts in biology and geology called the Commissioner's Advisory Committee (CAC) was formed to advise the DNR Commissioner on Natural Areas and to encourage the legislature to establish a program.
State-administered Scientific and Natural Areas were initially authorized by the Minnesota Legislature in 1969 (M.S. 84.033). The first Scientific and Natural Area, Rush Lake Island, was acquired in 1974 to preserve a heron rookery.
In 1980, an incentive for private landowners to preserve their prairie was added to the program. Native Prairie Tax Exemption allows for exempting eligible lands with native prairie from property taxes.
Natural Areas Registry recognizes public land containing exceptional natural features. Since 1982 the Scientific and Natural Area Program has developed agreements with land managers for ecological management of these areas.
Today, over 160 Scientific and Natural Areas and 120 Native Prairie Bank easements form the backbone of protected areas in the Program. These sites represent a diverse set of natural habitats across the state.
The Program's two largest sources of funding come through annual competitive grant processes and subsequent legislative approval. Funding sources include:
A number of organizations and individuals donate to the program. Of these, the Nature Conservancy has donated the most land. Sizable cash contributions have also been made by partners acquiring land for and with the program. Occasionally, the program receives federal funding.
