As with other species of woodrats, the white-throated woodrat constructs middens of a variety of materials such as sticks, cactus parts, and miscellaneous debris. Although occurring at lower elevations during the Pleistocene, it generally is limited now to highlands supporting open coniferous forests or woodlands. [13], The white-throated woodrat occupies a variety of plant communities from sea level to 9,200 feet (2,800 m)[7][16][17][18] but is most common in Sonoran and Chihuahuan desert grassland and desert shrub habitats. For example, vertebrate animals have a vertebral column, mammals produce milk to feed their young, and so on. Miscellaneous Publications No. their low hazard to pets and children.

[17][27] White-throated woodrats prefer to construct houses at the bases of plants that provide both adequate shelter and food. The standard rat snap trap is quite effective. Although any tree, shrub, or cactus may be used by white-throated woodrats for shelter sites,[7] the most commonly used plants are discussed below. Habitat relations of rodents in the Hualapai Mountains of northwestern Arizona. nocturnal and are most active during the half hour after sunset and at dawn, year round.

Woodrats are primarily [10] With the exception of lactating females, white-throated woodrats are solitary and occupy separate houses. [5][6], In general, white-throated woodrats occupy desert grasslands, semiarid shrublands,[9][13][14] saguaro (Carnegiea gigantea) cactus communities,[15] pinyon-juniper (Pinus-Juniperus spp.) National Audubon Society field guide to North American mammals.


The Mexican woodrat (Neotoma mexicana) is a medium-sized rat occurring in the United States from Utah and Colorado south through New Mexico and parts of Arizona and Trans-Pecos Texas.Its range continues south in the highlands to Honduras.Although occurring at lower elevations during the Pleistocene, it generally is limited now to highlands supporting open coniferous forests or woodlands. White-throated woodrats also dwelled in burrows with as many as 8 openings, covered with a few small twigs, at the bases of honey mesquite. woodrat control and are especially suited for use around structures because of [20] In the Cholla Garden in Joshua Tree National Park, white-throated woodrats depended on stands of jumping cholla (Cylindropuntia fulgida) for cover,[22] and in the Lower Sonoran zone of Arizona, most white-throated woodrat dens were found at the bases of cholla and prickly-pear. [38] An exception in habitat dominated by mesquite occurred on the Santa Cruz river bottom near Tucson, Arizona, where white-throated woodrat houses were also built under netleaf hackberry, American black elderberry (Sambucus nigra), skunkbush sumac (Rhus trilobata), bear grass (Nolina spp. In the case of the Woodrat, the animal is of the same superfamily as the Norway Rat (Sewer Rat) and the Black Rat (Palm Rat). 179–107, This page was last edited on 24 October 2020, at 01:48.
Anticoagulants are usually put out [7], In habitats where yucca are abundant white-throated woodrats use the base of yucca for shelter sites.

There are six species of woodrats in Colorado, with desert woodrats (12 inches long, 4 ½ ounces) the smallest, and the bushy-tailed woodrat of mountain talus slides (to over 16 inches long and 11 ounces) being the largest.

The active riparian channel and floodplain was dominated by desert willow, velvet ash, Arizona sycamore, and velvet mesquite.

Its natural habitats are boreal forests, temperate forests, dry savanna, temperate shrubland, and temperate grassland.

[18][37] Cactus parts are preferred building materials; preference for cacti is so strong that white-throated woodrat houses may not contain a proportionally representative sample of the surrounding plant community.

[21] In general, white-throated woodrats collect food within a 98- to 164-foot (30–50 m) radius of their dens.

On plots where white-throated woodrats were trapped, mean tree canopy cover ranged from 30% to 57%, mean herbaceous cover ranged from 2% to 10%, mean shrub cover ranged from 5% to 19%, and mean rock cover ranged from 3% to 14%. entrances to buildings, including those at the attic level, must be closed.

[26][32][33][34], In several studies in Arizona, white-throated woodrats preferred low tree cover and high shrub, rock, and litter cover. Their diet consists of seeds,[29][37] fruits,[14] green portions of plants,[14][21][37] flowers,[29] small amounts of grass,[14][19] and occasionally beetles (Coleoptera), ants (Hymenoptera),[7][14][37] and reptiles. [18], Predators of white-throated woodrat include weasels (Mustela spp.

Shelter and topography are important

[3] Populations east of the Rio Grande in New Mexico and Trans-Pecos Texas, previously considered to be variants of the white-throated woodrat, have since 1988 been assigned to the white-toothed woodrat (Neotoma leucodon).[4]. 45. grayish, bellies.
