Indiana’s occurrence data holds 1,290 records of the American red squirrel, one of the most frequently logged small mammals in the state’s mammal atlas. That volume stands out because Indiana sits mostly outside this species’ core conifer forest, so every record marks a spot where the right trees and cone crop line up.
A conifer specialist in a hardwood state
Red squirrels build their diet around conifer seeds, caching cut cones in large piles called middens under a favorite feeding perch. Most of Indiana is oak-hickory and beech-maple hardwood forest with few natural stands of pine or spruce, so the species leans on planted conifer groves in state forests and parks, the sandstone-ravine hemlock stands that survive in the unglaciated south, and the pine-and-oak dune ridges of the Lake Michigan shoreline in the north. Records concentrate wherever those conifer patches sit, not evenly across the state’s hardwood expanse.
A loud, visible animal even in a quiet season
Reports run high from February through June, when red squirrels actively defend cone caches and territory with the sharp, chattering scold that gives the species away long before it’s seen. Records fall off through late summer as cone crops mature and squirrels spend more time working the canopy than patrolling ground-level territory lines.
Status in Indiana
NatureServe ranks the American red squirrel S4, apparently secure, and native to Indiana. Its foothold in the state depends less on total forest acreage than on scattered conifer stands: planted pine rows, sandstone-ravine hemlocks, and dune-country pines that give this seed specialist somewhere to cache a winter’s worth of food.
