Oklahoma’s occurrence databases hold 99 records for the white-toothed woodrat, a modest share of the roughly 190 records mapped across its four-state range. Oklahoma sits at the eastern edge of a range centered on the Chihuahuan Desert borderlands of Colorado, New Mexico, and Texas.
A desert-edge species in Oklahoma’s canyon country
This packrat favors mid-elevation canyons and scrub, habitat that reaches into Oklahoma mainly through the gypsum breaks and canyon country of the western Panhandle and High Plains and doesn’t extend far into the wetter bottomland forest near Red Slough Wildlife Management Area or the Cross Timbers woodland around Lake Thunderbird State Park. Those eastern sites likely mark the outer fringe of where records turn up rather than the species’ real Oklahoma stronghold.
A midden-builder with a long memory
Like other packrats, it piles sticks, cactus pads, bones, and scavenged shiny objects into a bulky midden that shelters it from predators and temperature swings. Hardened old middens can preserve plant fragments for thousands of years, giving scientists a record of what desert vegetation looked like long before anyone was around to see it. Records here peak in Sep.
Status in Oklahoma
NatureServe ranks this species S3, Vulnerable, in Oklahoma, in keeping with how narrow its desert-edge habitat is here, and it’s native to Oklahoma.
