The Observation database is a statewide inventory of known locations and conditions of plant and animal species. Users must recognize that parts of the state remain uninventoried or under-inventoried. Thus, "the absence of evidence is not evidence of absence", nor does the documented presence of one species imply that other species were surveyed for but not found.
The Montana Natural Heritage Program (MTNHP) products and services are based on biological data and the objective interpretation of those data by professional scientists. MTNHP does not advocate any particular philosophy of natural resource protection, management, development, or public policy. MTNHP has no natural resource management or regulatory authority. Products, statements, and services from MTNHP are intended to inform parties as to the state of scientific knowledge about certain natural resources, and to further develop that knowledge. They are not intended at natural resource management guidelines or prescriptions.
Species range maps, habitat models, occurrence polygons, and other predictions of the spatial distribution of biological resources produced by MTNHP are objective extrapolations of credible data. They are intended to inform parties of the known occurrence or the likelihood of the presence of those resources, guide future surveys for those resources, and to test hypotheses regarding habitat quality and abundance. They are not intended to substitute for field-collected data, nor are they intended to be the sole basis for natural resource management decisions. We do not portray our databases as exhaustive or comprehensive inventories of rare species or of significant natural features. Field verification of the absence or presence of sensitive species will always be an important obligation of users of our data.
MTNHP assumes no liability for the use or misuse of this data.
