Species of rodent

The woodland jumping mouse (Napaeozapus insignis) is a species of jumping mouse found in North America. It can jump up to using its extremely strong feet and long tail.

Representatives of the family Dipodidae are found in the northern regions of the Old and New Worlds, and are characterized by very large infraorbital foramen, and, in one of the two North American genera, Zapus, by four upper cheek teeth. Incisors are compressed and deeply grooved. These animals are common and noted for very long tails and long hind legs adapted for leaping. They live in forests, meadows, and swamps and are profound hibernators. N. insignis was in the family Dipodidae, in the subfamily Zapodinae,

Eastern screech owls, timber rattlesnakes, bobcats, broad banded copperheads, American mink, weasels, and striped skunks are known predators. The mouse probably has a lifespan of two years but some may live for three or four years.

The woodland jumping mouse has no conservational status on the IUCN Red List, United States Federal List, or CITES. No major threats exist at present (2010) but land development reduces suitable habitat for species hibernation, and insufficient layers of insulating snowfall may result in high death rates during the winter. Southern populations are already confined to higher elevations in their range and are threatened by rising temperatures. More research is needed to evaluate and assess current distribution, species abundance, and potential effects of threats. No conservation measures have been undertaken at present to address specific needs of populations in state and national parks. The IUCN has listed the species as Least Concern, because the mouse is common and widespread, populations are considered stable, and no major threats exist at present.
