Boulder City Conservation Easement
The Boulder City Conservation Easement (BCCE) is a conservation easement located in Boulder City in Clark County, Nevada, Clark County in southwestern Nevada. It was designated in 1995 with an area of 86,538 acres to protect the Desert tortoise and other desert species. In 2018, at the request of the Boulder City Council, the boundaries of the BCCE were amended to include additional land adjacent to the Sloan Canyon National Conservation Area and exclude land immediately south of the original solar energy area. This change increased the city's conservation area by 2.2 percent and made nearly 2,000 more acres available for solar energy development. The Boulder City Conservation Easement includes land owned by the City of Boulder City. The City of Boulder is responsible for permitting activities under city ordinances, while Clark County is responsible for law enforcement and management of the BCCE. The BCCE may only be traveled on specifically authorized trails. In 1995, a 50-year co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Map Avi Kwa Ame National Monument
A map is a symbolic depiction of interrelationships, commonly spatial, between things within a space. A map may be annotated with text and graphics. Like any graphic, a map may be fixed to paper or other durable media, or may be displayed on a transitory medium such as a computer screen. Some maps change interactively. Although maps are commonly used to depict geography, geographic elements, they may represent any space, real or fictional. The subject being mapped may be two-dimensional such as Earth's surface, three-dimensional such as Earth's interior, or from an abstract space of any dimension. Maps of geographic territory have a very long tradition and have existed from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'of the world'. Thus, "map" became a shortened term referring to a flat representation of Earth's surface. History Maps have been one of the most important human inventions for millennia, allowin ...

Ferruginous Hawk
The ferruginous hawk (''Buteo regalis'') is a large bird of prey and belongs to the broad-winged buteo hawks. An old colloquial name is ferrugineous rough-leg, due to its similarity to the closely related rough-legged hawk (''B. lagopus''). The generic name ''buteo'' is Latin for 'buzzard'. The specific epithet ''regalis'' is Latin for 'royal' (from ''rex, regis'', 'king'). The common name 'ferruginous' means 'rust-colored' or 'reddish-brown'. This species is a large, broad-winged hawk of the open, arid grasslands, prairie and shrub steppe country; it is endemic to the interior parts of North America. It is used as a falconry bird in its native ranges. Description This is the largest of the North American ''Buteos'' and is often mistaken for an eagle due to its size, proportions, and behavior. Among all the nearly thirty species of ''Buteo'' in the world, only the upland buzzard (''B. hemilasius'') of Asia averages larger in length and wingspan. The weight of the upland buzz ...

Desert Iguana
The desert iguana (''Dipsosaurus dorsalis'') is an iguana species found in the Sonoran and Mojave Deserts of the Southwestern United States and northwestern Mexico, as well as on several Gulf of California islands. Taxonomy The species was first described in the ''Proceedings of the Academy of Natural Sciences of Philadelphia'', by Spencer Fullerton Baird and Charles Frédéric Girard, in 1852 as ''Crotaphytus dorsalis''. It was reclassified two years later as ''Dipsosaurus dorsalis'' by Edward Hallowell. The generic name comes from a combination of two Greek words meaning "thirsty lizard": "" () for "thirsty", and "" () for "lizard". The specific name, "dorsalis", comes from the Latin word ''dorsum'' meaning "spike", in reference to a row of enlarged spiked scales on the middle of the lizard's back which form a crest that extends almost to the tip of its vent. ''Dipsosaurus'' contains two species, ''D. dorsalis'', and ''D. catalinensis''. Genetic evidence supports ''Dipsos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long-nosed Leopard Lizard
The long-nosed leopard lizard (''Gambelia wislizenii'') is a species of relatively large North American lizard in the family Crotaphytidae. ''Gambelia wislizenii'' ranges in snout-to-vent length (SVL) from . It has a large head, a long nose, and a long round tail that can be longer than its body. It is closely related to the blunt-nosed leopard lizard (''Gambelia sila''), which closely resembles the long-nosed leopard lizard in body proportions, but has a conspicuously blunt snout. The species ''G. wislizenii'', once considered part of the genus ''Crotaphytus'', is under moderate pressure because of habitat destruction but is categorized as "least concern". Etymology The specific name or epithet, ''wislizenii'', is in honor of the German-American surgeon and naturalist Frederick Adolph Wislizenus, who caught the first specimen near Santa Fe, New Mexico. Description ''Gambelia wislizenii'' has granular dorsal scales that can be white, cream, or gray with irregular brown or da ...

Mojave Rattlesnake
''Crotalus scutulatus'' is known commonly as the Mohave Rattlesnake. Other common English names include Mojave Rattlesnake Stebbins, R.C. (2003). ''A Field Guide to Western Reptiles and Amphibians''. Boston: Houghton Mifflin & Co. pp. 416–417. Campbell JA, Lamar WW (2004). ''The Venomous Reptiles of the Western Hemisphere''. Ithaca and London: Comstock Publishing Associates. 870 pp., 1,500 plates. . and, referring specifically to the nominate (northern) subspecies: Northern Mohave Rattlesnake and Mojave Green Rattlesnake, the latter name commonly shortened to the more colloquial “Mojave green”. Campbell and Lamar (2004) supported the English name “Mohave (Mojave) rattlesnake” with some reluctance because so little of the snake’s range lies within the Mojave Desert. The spelling of the English name with an “h” has been advocated by multiple authors in recent years for various reasons. The most recent iteration of standard English names for North American reptiles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zebra-tailed Lizard
The zebra-tailed lizard (''Callisaurus draconoides'') is a species of lizard in the family Phrynosomatidae. The species is native to the Southwestern United States and adjacent northwestern Mexico. There are nine recognized subspecies. Habitat Zebra-tailed lizards live in open desert with hard-packed soil, scattered vegetation, and scattered rocks, typically flats, washes, and plains. Description Zebra-tailed lizards range in size from in snout-to-vent length (SVL). These lizards are grey to sandy brown, usually with a series of paired dark gray spots down the back, becoming black crossbands on the tail. The underside of the tail is white with black crossbars. Males have a pair of black blotches on their sides, extending to blue patches on their bellies. Females have no blue patches, and the black bars are either faint or completely absent. Behavior Zebra-tailed lizards are diurnal and alert. They rise early and are active in all but the hottest weather. During the hottest ...

Gila Monster
The Gila monster (''Heloderma suspectum'', ) is a species of venomous lizard native to the Southwestern United States and the northwestern Mexico, Mexican state of Sonora. It is a heavy, slow-moving reptile, up to long, and it is the only venomous lizard native to the United States. Its venomous close relatives, the four Mexican beaded lizard, beaded lizards (all former subspecies of ''Heloderma horridum'') inhabit Mexico and Guatemala. The Gila monster is sluggish in nature, so it is not generally dangerous and very rarely poses a real threat to humans. However, it has a fearsome reputation and is sometimes killed despite the species being protected by state law in Arizona. History The name "Gila" refers to the Gila River Basin in the U.S. states of Arizona and New Mexico, where the Gila monster was once plentiful. ''Heloderma'' means "studded skin", from the Ancient Greek words (), "the head of a nail or stud", and (), "skin". The species epithet ''suspectum'' comes fr ...

California Kingsnake
The California kingsnake (''Lampropeltis californiae'') is a nonvenomous colubrid snake endemic to the western United States and northern Mexico, and is found in a variety of habitats. Due to ease of care and a wide range of color variations, the California kingsnake is one of the most popular snakes in captivity. Description Wild California kingsnakes are typically encountered at a length of 2.5-3.5 feet (76 – 107 cm), though they can grow larger; California kingsnakes on Isla Ángel de la Guarda, Baja California, Mexico, have been documented growing to 78 inches (2 m). A wide range of color morphs exist in the wild; they are usually found with alternating dark and light bands ranging in color from black and white to brown and cream. Some populations may have longitudinal stripes instead of bands. Most California kingsnakes live to be around ten to fifteen years old, even surpassing twenty if well cared for in captivity. California kingsnakes stripes and bands are es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kit Fox
The kit fox (''Vulpes macrotis'') is a fox species that inhabits arid and semi-arid regions of the southwestern United States and northern and central Mexico. These foxes are the smallest of the four species of ''Vulpes'' occurring in North America and are among the smallest of the vulpines worldwide. It has also been called a North American counterpart of the fennec fox due to its large ears. Taxonomy Some mammalogists classify it as conspecific with the swift fox, ''V. velox'', but molecular systematics indicate that the two species are distinct. Interbreeding between the two species does occur where their ranges overlap (eastern New Mexico and western Texas), but this hybridization is quite restricted in scope. Subspecific designations for the species are not fully addressed. As many as eight subspecies have been recognized, although further analyzes have not found support for any subspecies differentiation. However, although there is a clear need for more subspecific clarifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LeConte's Thrasher
LeConte's thrasher (''Toxostoma lecontei'') is a pale bird found in the southwestern United States and northwestern Mexico. It prefers to live in deserts with very little vegetation, where it blends in with the sandy soils. LeConte's thrashers are nonmigratory birds that reside in the same territory annually. Although the species has been decreasing in certain areas of its range, in particular California, it still is abundant enough to not be considered for vulnerable status. These birds are terrestrial and only fly occasionally. Both sexes are heavily involved in the nest building, incubating, and brooding process, though each alternates with primary responsibility of the tasks. LeConte's thrashers frequently compete with species such as the northern mockingbird, loggerhead shrike and greater roadrunner, as well as being potential prey for the latter. Taxonomy LeConte's thrasher is named after Dr. John Lawrence LeConte, an entomologist who eventually became president of the Am ...
