Prairie Vole (Microtus ochrogaster) Conservation Status Review
Review Date = 05/03/2018
ScoreG - 200,000-2,500,000 km squared (about 80,000-1,000,000 square miles)
Comment266,624 square Kilometers from Natural Heritage Program range maps
ScoreE - Relatively Stable (±25% change)
CommentHabitat is likely stable within +/- 25% since European settlement
ScoreU - Unknown. Short-term trend in population, range, area occupied, and number and condition of occurrences unknown.
CommentNo data on trends available
ScoreF - Widespread, low-severity threat. Threat is of low severity but affects (or would affect) most or a significant portion of the population or area.
CommentLoss of sagebrush habitat through fire, resource extraction, exotic plant invasion, or conversion to agriculture
SeverityLow - Low but nontrivial reduction of species population or reversible degradation or reduction of habitat in area affected, with recovery expected in 10-50 years.
CommentLoss of sagebrush habitat through fire, resource extraction, invasive could reduce population
ScopeModerate - 20-60% of total population or area affected
CommentThreats could be widespread
ImmediacyHigh - Threat is operational (happening now) or imminent (within a year).
CommentThreat is operational
ScoreC - Not Intrinsically Vulnerable. Species matures quickly, reproduces frequently, and/or has high fecundity such that populations recover quickly (< 5 years or 2 generations) from decreases in abundance; or species has high dispersal capability such that extirpated populations soon become reestablished through natural recolonization (unaided by humans).
CommentNot Intrinsically Vulnerable. Species matures quickly, reproduces frequently, and/or has a high fecundity such that populations recover quickly (< 5 years or 2 generations) from decreases in abundance. Species has good dispersal capabilities such that e
ScoreC - Moderate. Generalist. Broad-scale or diverse (general) habitat(s) or other abiotic and/or biotic factors are used or required by the species but some key requirements are scarce in the generalized range of the species within the area of interest.
