Western Fence Lizard (Sceloporus occidentalis )

Posted on by

The Western Fence Lizard ( Sceloporus occidentalis ) is perhaps one of the most common lizards in the desert southwest and is also known as a “Blue belly”. Perhaps this commonality is the reason for its name. The Western Fence lizard is found in a variety of habitats and common at elevations up to 10,800 feet. They can be located in forests, desert sage, farmlands and grasslands. This species is typically not found in harsh desert climates and moist forests.

This animal is typically between 2 inches and 3.5 inches in length. They are typically black to brown in colors with stripes on their backs. They have blue colored patches on their ventral abdomen. This reptiles will lay clutches of eggs between 3 and 17 eggs in the spring between April and July. The eggs will hatch within two months of feralization.

This animal are known to eat insects including ant, beetles, flies, spiders and some caterpillars. They typically can be found sunning themselves on rocks, fences and paths. The are a prey item for other animals including larger lizards, birds and also some a mammals. As is common with most reptiles, the lizard is known to hibernate in cooler winter months.

Commonly known as an antelope, the Pronghorn ( Antilocapra americana ) is an even toed or hoofed mammal found in the plains of the western United States of America. The Pronghorn in america is mislabeled as an antelope, which is an old world or African species of Antelope. The Latin name, Antilocapra americana means “American goat-antelope”

The Pronghorn lives in brush and grass lands and deserts and survive by grazing on the vegetation. They typically live in herds which may number in the hundreds depending on time of year and food sources.

They have excellent eye sight use this valuable resource to keep a distance from predators in the wide open habitats they are found. They are also the fastest animal in the western hemisphere and can run at speeds up to 60 miles per hour. The result is a reclusive animals that tends to run when it sees any threat, which means these animals can be difficult to get near. Typically, when I see them in the field, it is their white hind quarters travelling at a high rate of speed away from me.

Males typically stand between 51 and 59 inches in height and weigh between 88 and 143 pounds. The female are about the same height, however, more slight at 75 to 106 pounds. Their coloring is quite distinctive and features large white patches on the rumps, belly and heads with black bands on the face and necks. They boast large eyes located towards the tops of their skulls which have a field of view of 320 degrees. This feature allows the animals to maintain distance and allows them to spot predators while resting in the tall grass.

Cougers, Coyotes, Wolfs and Bob Cats are known to prey on the pronghorn. Additionally, they were a valuable food source for many Native American tribes including the Assiniboine, Rapid and Blackfoot Tribes.

The Black Tailed Jackrabbit (Lepus californicus) commonly known as the American Desert Hare makes its home in the western half of the United States including California, Nevada, Arizona and parts of Mexico. One of the largest species of hare, the animal boasts large distinctive ears, powerful rear legs, black tips on its ears and a black tail for which the animal gets its name.

This species of hare commonly reaches sizes of 18 to 24 inches long and may weigh between 4 and 8 pounds. Typically, the females are slightly larger compared to the males. The animal will mate ear round depending upon environment and the young are born with a full compliment of fir and open eyes, which classifies it as a true hare and not a rabbit, despite its common name. The female does not build elaborate nests for birth. A new born hare is and well camouflaged and quite mobile within minutes of birth. The juveniles will stay near the mother for nursing, but are not protected by the mother.

Commonly found in desert scrub, prairies and meadows at elevations up to 10,000 feet, the Black Tailed Jackrabbit is quite adaptive to various environments. Camouflage is their only defense, and they will freeze when a threat is near. Their diet consists of a variety of green vegetation and grasses, however they are known to consume dried or woody plants in the harsh winter months. The hare does not hibernate during the winter months.

The Black Tailed Jackrabbit is a valuable member of the ecosystem. It serves as a prey item of other carnivorous animals including coyotes, foxes, eagles, hawks, owls and various Native American tribes.

Snow plant (Sarcodes sanguinea)

The Snow plant (Sarcodes sanguinea) is a rather rare and unique member of the plant community. The scientific name roughly translates to “the bloody flesh-like thing” and named by John Torrey, who was a 19th century botanist. The name is easily understood when walking through a snowy section of mountains and you happen across a bright red plant.

This solitary little plant is completely red is color due to its complete lack of chlorophyll. Unable to photosynthesize, this plant derives its nutrition from a mutual-ism between the plant and a fungus. The snow plant provides fixed carbon to the fungus, and in return, the plant leaches sugars from the fungus.

The red flowered plant typically appears just before the last of the snows of winter. The above ground stalk typically does not exceed 12 inches in height. The plant is typically founded in the conifer forests of California, Oregon and parts of western Nevada. The plants are essentially parasites to the conifers and as such, typically found close to them.

The flowers of the snow plant are typically tightly packed around the singular stalk and evenly spaced. The plant is typically bright red in color and the fruit is pinkish red.

Mustang (Equus ferus caballus)

Left behind by Spanish explorers and settlers, the Mustang ( Equus ferus caballus ) of the desert south west is alive and well in Nevada and a symbol of the southwest. Due to the fact that this animal population is descendant from a domesticated population the Mustang is actually a feral horse. The imagery of a wild mustang galloping across the desert as burnt into the memories of kids who watched “Western” movies or appreciate classic cars. The wild mustang brings one to think of power and freedom.

There is much debate when it comes to the wild Mustangs of Nevada. Some will debate weather you consider them an invasive species and a natural species. However, you consider them, they are thriving and a part of the landscape at this point. Should you happen upon them, you can not help but feel lucky.

The wild horse populations are separated by long distances, so each isolated herd has developed specific genetic traits. Some consider the horse populations a nuisance which destroy the terrain with their appetite. Their hooves can be quite destructive to the landscape and ranch land. Although considered “culturally significant”, the horse populations are closely monitored by the Bureau of Land Management to ensure healthy herd populations.

Population increases of about 20% per year have prompted the BLM to capture some of the horses. The captured horses are not euthanized, and instead are available for adoption for the cost of $125. Horses which are not adopted are held in “long term holding”, which costs the US Tax Payer about $50,000 over the lifetime of each individual horse.

On a trip to see the mustangs near Cold Creek, Nevada, we ran across the local herd lazily walking along the side of the road. We slowed the jeep down, and which point the horses started to walk up to the car looking for some food (which we did not provide). Not exactly the in line with the western movies of my youth.
