What food source is the Allegheny woodrat highly reliant upon for winter survival?

Answer

Cached hard mast, such as acorns

The Allegheny woodrat exhibits a specialized dependency on high-energy, long-lasting food sources, specifically hard mast crops which primarily include acorns from oak trees. This reliance is so pronounced that their population stability often directly correlates with the success of the annual acorn yield, referred to as the mast cycle. By meticulously gathering and caching these energy-dense items throughout the autumn, they secure the necessary reserves to sustain them throughout the colder months when other food sources, like fresh vegetation, become scarce or inaccessible. This caching behavior is explicitly noted as crucial for their winter survival.
