Bushy-tailed woodrat has exactly one confirmed record in Arizona’s dataset, logged in April 2024, which places it near the very bottom of the state’s mammal count. Arizona sits at the southern edge of this packrat’s range, which otherwise runs through the higher, cooler country of the Rocky Mountains and Colorado Plateau.
A single record from a talus-and-cliff specialist that builds elaborate stick middens in rock crevices says more about how little that terrain gets surveyed than about true scarcity, though an edge-of-range population is genuinely expected to be thin.
