Deer Family (Cervidae)Tule Elk is the smallest subspecies of North American elk (Cervus canadensis)(Linse 1. Types of Rats. Learn about common rat species found in homes throughout the United States. Contact Critter Control for help with a rat infestation. With its bright yellow plumage, the Eurasian golden oriole (Oriolus oriolus) is an incredibly striking bird. On the male Eurasian golden oriole, this beautiful. Tule elk: Found only in California. Historically occurred in the Central Valley and coastal regions of central California (Linse 1. Occur only in grasslands and marshlands (Linse 1. Tule Elk Ecology. Grazing. Tule Elk graze on grasses and forbs, then move to browse (shrubs and trees) as herbaceous plants dry out (Jameson Jr. While significant dietary overlap occurs with other local ungulates, Elk favor forbs (with a lower proportion of grass and browse); cattle favor grasses (with a lower proportion of forbs and very little browse), and black- tailed deer favor forbs and browse in roughly equal proportion with a lower proportion of grasses contributing to their diet (Findholt et al. Although grasses are the primary component of their fall diets, Tule Elk eat very little non- native annual bromes, such as Soft Brome (Bromus hordaceus) and Ripgut Brome (Bromus diandrus) (Gogan and Barret 1. Howard 1. 99. 8). Elk canine teeth were used as the traditional pendant of the Elk’s Club (Jameson Jr. Through intensive hunting after the goldrush, their numbers plummeted. The Point Reyes herd is now one of the largest populations in California with over 4. National Park Service 2. Walter Siegmund. Deer Family (Cervidae)Black- tailed deer is the coast range form of the mule deer (Odocoileus hemionus). Black- tailed Deer Ecology. Grazing. Black- tailed deer graze on grasses and forbs and browse on the leaves, twigs, and shoots of shrubs and small trees (Jameson Jr. Botta's Pocket Gophers (Thomomys bottae) - native.

Gopher Family (Geomyidae)Botta's pocket gopher has a missile- shaped body. The coloration of its fur is highly variable and is correlated with color of the surrounding soil. Botta's Pocket Gopher: Is native to western North America. It is also known in some sources as valley pocket gopher, particularly in California. Is one of five species of pocket gophers (Thomomys spp.) in California (Salmon and Gorenzel 2. At some sites, gopher mounds bury as much as 2. Koide et al. 1. 98. Soil deposited by gophers at the surface is generally free of seeds, and the differential ability of plants to colonize the areas determines the composition of the resulting community on these patches (Douglas 1. Hobbs and Hobbs 1. Hobbs and Mooney 1. Koide et al. 1. 98. Because non- native species tend to be excellent colonizers, gopher mounds can enhance the growth of non- native species. Some land managers have taken advantage of the . Weasels and snakes (including gopher and rattlesnakes) pursue gophers into their burrows. Badgers, and (historically) grizzly bears (Mattison 2. Many different predators prey on gophers when they are aboveground feeding, dispersing, or constructing mounds. These include coyotes, domestic dogs, foxes, house cats, striped skunks, bobcats, raptors, owls and herons (Case 2. Bobcat (Lynx rufus) eating gopher, California, USA. November 2. 00. 9. Linda Tanner. Wikimedia Commons: http: //commons. File: Bobcat. Tunneling underground is a tremendously demanding activity estimated to require 3. Most amphibians and lizards are ignored by gophers. Ground squirrels, kangaroo rats, and smaller rodents use gopher burrows but tend to leave the tunnel if it is occupied by a gopher (Case 2. Grazing. Pocket gophers are strict herbivores and feed on forbs, grasses, shrubs, and trees in three ways: (1) they feed on roots that they encounter when digging; (2) they may go to the surface, venturing only a body length or so from their tunnel opening to feed on aboveground vegetation and seeds; and (3) they pull vegetation into their tunnel from below (Case 2. Grasses are. often consumed entirely (Gettinger 1. Proportions of plants consumed vary seasonally. Gophers eat a greater amount of aboveground vegetation (shoots, leaves) during the growing season when the vegetation is green and succulent. Year- round, however, roots are the major food source, and they eat a variety of fleshy underground storage structures, such as bulbs, rhizomes, corms, and tubers (Case 2. Dandelions are a preferred food. At a density of 2. Botta’s pocket gophers decreased the forage yield by 2. California foothills. Similar consumption rates were measured in western Nebraska rangelenad, where plains pocket gophers reduced forage yield 2. Case 2. 00. 8). Soil Disturbance: Botta's Pocket Gopher (Thomomys bottae) with fresh mound. February 2. 00. 8. Dominic Sherony. Burrows are, generally 4 to 1. Deeper burrow branches, which can reach down to 5 or 6 feet (1. A single burrow system may contain up to 2. Case 2. 00. 8). Gopher burrowing activity brings large amounts of soil to the surface. The number of soil mounds on the surface of the ground can reach 3. Case 2. 00. 8). Potential benefits of pocket gopher soil disturbance are: (1) increased soil fertility by adding organic matter such as buried vegetation and fecal wastes; (2) increased soil aeration and decreased soil compaction; (3) increased water infiltration and thus decreased runoff; and (4) increased rate of soil formation by bringing subsoil material to the surface of the ground, subjecting it to weathering (Case 2. Fun Facts About Pocket Gophers. Pocket gophers are named for the two fur- lined pouches, one on the outside of each cheek, in which they transport collected food to underground storage chambers. The pouches can be turned inside out (Case and Jasch 2. Pocket gopher fossils have been found from Rancholabrean deposits in California, and the oldest fossil is 1. Long Beach California (Jones and Baxter 2. As with all rodents, the incisors of pocket gophers grow continuously and gophers must gnaw to keep their teeth ground to an appropriate length. Gophers exert tremendous pressure with their bite, up to 1. Case 2. 00. 8). California Meadow vole, California vole (Microtuscalifornicus) - native. Microtus californicus, at the Piedras Blancas Lighthouse, San Luis Obispo County, California. May 2. 01. 0, Jerry Kirkhart, Wikimedia Commons. Vole and Hamster Family (Cricetidae)California meadow voles (Microtus californicus) are burrowing mouse- like rodents with short tails. There are six species of voles or meadow mice in California and the California meadow vole is the most widespread in the state. California Meadow Vole: Found in a variety of habitats where grasses occur. California Meadow Vole Ecology. Grazing: California voles can be detected by their characteristic system of runways visible in the grass that connect their burrow openings (Salmon and Gorenzel 2. California voles feed on the stems and leaves of grasses during the wet season and switch to grass seeds during the summer (Batzli 1. In the winter, voles also rely on roots and underground plant parts (Burt and Grossenheider, 1. Ingles, 1. 96. 5 cited in Peronne 2. One study in a San Francisco Bay coastal prairie found that California voles preferred non- native annual grasses (Avena, Festuca perenne, and Bromus spp. This is mostly likely due to higher survival during the summer (Cockburn and Lidicker 1. Heavy grazing by M. Breeding can occur thorughout the year in coastal populations, where the grasses stay green all year, and temperatures are mild (Peronne 2. California voles seem mostly monogomous when populations are low. Photo by Elaine Bond 2. Because vole populations are lower, there are fewer raptors, such as white- tailed kites, in grazed grasslands (Johnson and Horn 2. Vole predators are numerous and include coyotes, kestrels, hawks, weasles, kits, owls, snakes, herons, egrets, and feral cats. Voles are the primary food source for grassland raptors and mammal carnivores. Black- tailed jackrabbit (Lepus californicus) - native. Black- tailed jackrabbit eating berries. June 2. 00. 6, James Marvin Phelps, Wikimedia Commons. Rabbit Family (Leporidae)Black- tailed jackrabbits are large, long- eared rabbits of the open grasslands. Black- tailed Jackrabbit: The most widely distributed jackrabbit in North America. Rangeland overbrowsing and overgrazing can occur any time jackrabbit numbers are high. Eight jackrabbits are estimated to eat as much as one sheep, and 4. Range damage can be severe in such situations, especially where vegetation productivity is low (Knight 1. Fun Facts About Jackrabbits. The name “jackrabbit” came from early settlers in the Southwest who called it “jackass rabbit” because of its long donkey- like ears (Ballenger 1. Jackrabbits prefer well- grazed grasslands. Howard (1. 99. 5) cites a study that suggests that jackrabbit populations can be controlled by keeping rangelands in excellent condition (i. Daniel et al (1. 99. Christopher Bruno. In the past, now extinct megafaunal browsers and grazers once supported (as prey) a different set of megafaunal carnivores in coastal prairies. Coyote (Canus latrans) Gray fox (Urocyon cinereoargneteus) Red fox (Vulpes vulpes) Ringtail (Vassariscus astutus) Mountain lion (Felis consolor) Bobcat (Lynx rufus) Feral house cat (Felis catus), introduced Black bear (Ursus americanus) - native. A brown American Black Bear cub seen west of Boulder, Colorado, dining on bunch grass. Bear Family (Ursidae)Black Bear: Is native to much of North America. Fun Facts About Black Bear. Black bears were found on Point Reyes until about 1. Kawahara 1. 97. 0). In September and October 2. Eurasian golden oriole videos, photos and facts - Oriolus oriolus. The Eurasian golden oriole commences breeding in April, when it arrives at its breeding grounds. The female constructs an impressive hammock- like nest, which is woven from grasses, moss and lichens, and suspended from a fork in a tree (6). Into this deep nest the female lays three to four white eggs, speckled with black spots. The eggs are incubated for 1. The chicks are fed insects by the male and female until they are able to fly at around 1. The diet of the Eurasian golden oriole comprises mainly insects. It prefers caterpillars, but will also feed on small vertebrates, such as mice (6). Eurasian golden oriole chicks are fed a large number of bumblebees (7). In autumn, towards the end of the breeding season, a greater proportion of calorie- rich fruits and berries are eaten, which help the Eurasian golden oriole to build fat reserves in preparation for its long migration south (6). In July, the Eurasian golden oriole starts its migration to the warmer climes of Africa (6). This species can live for up to ten years (3).
