| From the map it appears that Allen's Woodrat is widespread, but it is apparently only locally abundant. It needs habitat where it can find dense cover. Where mesquite, agave, rocks, thorn scrub, or debris cover the ground, it digs burrows and creates numerous trails. Unlike other woodrats, it does not build large nests, but occasionally it collects sticks and other treasures. Not much information is available about reproduction in Allen's Woodrat. One female was found to be carrying a single embryo. Another, chased from a house, was followed by two offspring.
