HABITAT USE AND HOME RANGE OF LONG-NOSED LEOPARD LIZARDS (GAMBELIA WISLIZENII) IN CANYONS OF THE ANCIENTS NATIONAL MONUMENT, COLORADO 1,3 1 2 ROBERT A. SCHORR , BRAD A. LAMBERT , AND ERIC FREELS 1Colorado Natural Heritage Program, Colorado State University, Fort Collins, Colorado 80523, USA 2Dolores Public Lands Office, San Juan Public Lands, 100 North Sixth Street, Box 210, Dolores, Colorado 81323, USA 3Corresponding author, e-mail: [email protected] Abstract.—An understanding of species’ habitat requirements is needed for effective land management decisions, but for many North American reptiles, habitat use information is lacking. Gambelia wislizenii (Long-nosed Leopard Lizard) is a predatory lizard of most North American deserts, and, although common in the interior of its range, appears to be declining at some peripheral populations. To understand habitat use and movement patterns, we used telemetry and two habitat comparison methods to study a G. wislizenii population at the eastern boundary of the range. Gambelia wislizenii home ranges at Canyons of the Ancients National Monument, Colorado, are the largest recorded. Habitat analysis using microsite-attribute comparisons and compositional analysis documented second-order habitat preference for Big Sagebrush- or Utah Juniper-dominated landscapes. Gambelia wislizenii were found in areas with moderate shrub and forb cover with much bare ground, but were not found in areas dominated with grass cover. Incorporating management strategies that limit grass encroachment and maintain bare ground cover with moderate tree and shrub cover may help sustain G. wislizenii populations.

Marlow Reviewed by: T. Papenfuss Edited by: S. Granholm Updated by: CWHR Program Staff, March 2000 DISTRIBUTION, ABUNDANCE, AND SEASONALITY The long-nosed leopard lizard is widely distributed in the Southeastern Great Basin, Mojave, Sonoran and Colorado deserts of California and at the southern end of the Central Valley in Santa Barbara and eastern Kern cos. Frequents a variety of desert woodland and scrub habitats up to 1830 m (6000 ft) (Stebbins 1985). Prefers sandy or gravelly flats and plains, and is less common in rocky areas. The greatest densities have been observed in creosote flats. Becomes active later in the spring than do other lizards, usually not until mid-April, and is not found after mid-August (Stebbins 1954, McCoy 1967, Montanucci 1967, Parker and Pianka 1976, Tollestrup 1979, 1983). SPECIFIC HABITAT REQUIREMENTS Feeding: This lizard eats insects (grasshoppers, beetles, etc.), lizards (Callisaurus, Cnemidophorus, Phrynosoma, etc.) and occasionally some plant material (Stebbins 1954, Dixon 1967, Tollestrup 1979). Cover: This species excavates its own burrows in sandy and friable soils and probably uses rodent burrows. Reproduction: This lizard requires adequate food supplies for reproduction. Water: Not required. Pattern: This lizard occupies desert flats and woodlands with sandy or gravelly substrates. SPECIES LIFE HISTORY Activity Patterns: Adults are active from mid-April to mid-August. This lizard is diurnal and can be active all day when the weather is mild to warm.

California Wildlife Habitat Relationships System California Department of Fish and Wildlife California Interagency Wildlife Task Group BAJA CALIFORNIA COLLARED LIZARD Crotaphytus vestigium Family: CROTAPHYTIDAE Order: SQUAMATA Class: REPTILIA R093 Written by: T. Kucera, 1998 Updated by: CWHR Staff, February 2008 DISTRIBUTION, ABUNDANCE, AND SEASONALITY The Baja California collared lizard inhabits the eastern face of the peninsular ranges and adjacent rocky slopes from the northern slope of the San Jacinto mountains to the Mexican border and south into Baja California, Mexico (Sanborn and Loomis 1979, McGuire 1996). It is generally restricted to rocky outcroppings on more rugged portions of alluvial fans, desert hillsides, canyons, and lava flows. It is most common in xeric, rocky areas with little vegetation, including desert succulent shrub, desert scrub, and desert wash habitats. Little has been written about its natural history. The Baja California collared lizard is active in the spring and summer and to a lesser extent in the fall. SPECIFIC HABITAT REQUIREMENTS Feeding: Little is known of the diet of this species. The diet of the closely related Mojave black- collared lizard (C. bicinctores) consists largely of arthropods and small vertebrates (Stebbins 1985, McGuire 1996). Plant material is also occasionally consumed. Cover: This species prefers rocky areas and seeks cover under rocks and in cracks and crevices and rodent holes (Stebbins 1985), occasionally bounding bipedally from stone to stone when disturbed (McGuire 1996). Reproduction: Little is known about the reproductive requirements of this species. The closely related Mojave black-collared lizard lays eggs and presumably constructs its own nest but there are no reports.

Impacts of Off-Highway Motorized Vehicles on Sensitive Reptile Species in Owyhee County, Idaho
Impacts of Off-Highway Motorized Vehicles on Sensitive Reptile Species in Owyhee County, Idaho by James C. Munger and Aaron A. Ames Department of Biology Boise State University, Boise, ID 83725 Final Report of Research Funded by a Cost-share Agreement between Boise State University and the Bureau of Land Management June 1998 INTRODUCTION As the population of southwestern Idaho grows, there is a corresponding increase in the number of recreational users of off-highway motorized vehicles (OHMVs). An extensive trail system has evolved in the Owyhee Front, and several off-highway motorized vehicle races are proposed for any given year. Management decisions by the Bureau of Land Management (BLM) regarding the use of public lands for OHMV activity should take account of the impact of OHMV activity on wildlife habitat and populations. However, our knowledge of the impact of this increased activity on many species of native wildlife is minimal. Of particular interest is the herpetofauna of the area: the Owyhee Front includes the greatest diversity of reptile species of any place in Idaho, and includes nine lizard species and ten snake species (Table 1). Three of these species are considered to be "sensitive" by BLM and Idaho Department of Fish and Game (IDFG): Sonora semiannulata (western ground snake), Rhinocheilus lecontei (long-nosed snake), and Crotaphytus bicinctores (Mojave black-collared lizard). One species, Hypsiglena torquata (night snake), was recently removed from the sensitive list, but will be regarded as "sensitive" for the purposes of this report. Off-highway motorized vehicles could impact reptiles in several ways. First, they may run over and kill individuals.

Gambelia Wislizenii)
AN ABSTRACT OF THE THESIS OF Edith Moore for the degree of Master ofScience in Zoology presented on August 16, 1983 Title:The Function of Orange Breeding Coloration in the Social Behavior of the Long-nosed Leopard Lizard (Gambelia wislizenii) Abstract approved: _Redacted for Privacy Dr. Robert M. Storm The role of orange coloration in the breeding behavior of Gambelia wislizenii was examined in the Alvord Basin of southeast Oregon. Behavioral observations of free ranging lizards supplemented field experiments where I manipulated the sex and color of lizards encountered by resident female G. wislizenii before and after they acquired orange coloration. G. wislizenii exhibited a behavioral repertoire typical of the family Iguanidae. Twenty-four behaviors were observed and discussed in the text. Female G. wislizenii avoided plain females and males early in the breeding season, while males courted both indiscriminately. Female avoidance forced males to pursue females in order to secure the neck grip necessary for copulation. Female coyness may exert selective pressure on males to display characteristics thatwould improve their offspring's chances of survival. Possible advantages of male-male "courtship" are discussed. Most orange females were unreceptive to male courtship and reacted with overt aggression to such advances. Males may maintain a neck grip on females for up to three hours, thereforeit is to a gravid female's advantage to discourage male courtship, and thus avoid unnecessary incapacitation. The high level aggression of orange females was usually an effective deterrent to male courtship; however, a rape strategy was substituted for courtship on occasion. The rape strategy was characterized by 10-20 m headlong dashes ending in a tackle of the female.

California Wildlife Habitat Relationships System California Department of Fish and Wildlife California Interagency Wildlife Task Group BLUNT-NOSED LEOPARD LIZARD Gambelia sila Family: CROTAPHYTIDAE Order: SQUAMATA Class: REPTILIA R019 Written by: G. Ahlborn Reviewed by: P.A. Medica Edited by: G. Ahlborn Updated by: CWHR Program Staff, March 2000 DISTRIBUTION, ABUNDANCE AND SEASONALITY Scarce resident of sparsely vegetated alkali and desert scrub habitats. Distribution has been extensively reduced by conversion of habitat to cropland. Currently occurs at scattered sites in the San Joaquin Valley and adjacent foothills. Found at elevations of 30 to 730 m (100 to 2400 ft) (Stebbins 1985) on alkali flats, large washes, arroyos, canyons, and low foothills. SPECIFIC HABITAT REQUIREMENTS Feeding: Blunt-nosed leopard lizards are carnivorous. They are opportunistic foragers that hunt on the ground, catching grasshoppers, cicadas and small lizards (including smaller leopard lizards). They commonly forage by slowly stalking prey, then rapidly dashing in to capture it. Cover: Shade for leopard lizards is provided by mammal burrows, shrubs or structures such as fence posts. Apparently leopard lizards do not excavate their own burrows. Reproduction: Females sometimes excavate nests by altering vacated mammal burrows (e.g., kangaroo rats, California ground squirrels) to form a closed chamber approximately 50 cm (20 in) below the soil surface. Water: Apparently no requirement for water. Pattern: Suitable habitat for leopard lizards is characterized by sparsely vegetated scrub and grassland habitats in areas of low topographic relief. In areas of high relief, distribution is usually confined to broad sandy washes. Do not appear to use slopes > 30-40 degrees (Germano and Williams 1992).
