Block Island Meadow Vole
A distinct meadow-vole subspecies lives only on Block Island, where fields, shrub edges, predators, and island history shape its whole range.

The Block Island meadow vole is a dark, robust island form of the widespread meadow vole. It uses grassland and herbaceous cover, feeding on green plants and seeds while building runways beneath vegetation. Because every natural population occurs on one small island, ordinary land-use changes can influence the subspecies at range-wide scale.
Voles are important prey for owls, hawks, foxes, and snakes, and their hidden tunnels redistribute plant material through the meadow. Seeing one is less likely than finding clipped grass or narrow runways. Do not lift boards, dismantle stone edges, or set traps for a casual identification; the island context is the most important clue.
- Range
- Block Island only
- Cover
- Grassland and field edges
- Role
- Prey and plant consumer
Quick guide
- Search indirectly
- Notice runways under dense grass.
- Keep scale
- Short tail and hidden ears separate a vole from a mouse.
Recognize an island vole by form and place
- Body
- Stocky shape with a blunt muzzle and ears partly hidden by fur.
- Tail
- Much shorter than the head-and-body length of a typical mouse.
- Signs
- Narrow surface runways and clipped vegetation may be more visible than the animal.
- Limits
- Subspecies identification depends on Block Island provenance, not appearance alone.
Good to know
A photograph of a meadow vole elsewhere cannot be labeled as this subspecies. The identification is geographic and taxonomic, so an exact, ethical Block Island record matters more than subtle coat color.
Notice these
- Stocky brown body
- Short tail
- Partly hidden ears
