This book was released on 2009 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document summarizes a great deal of information on the distribution, status, and biology of amphibians and reptiles known or thought to potentially inhabit Montana and is intended to become a dynamic living document that can be updated on a regular basis from research conducted in Montana or elsewhere. The document will be posted on the Montana Natural Heritage Programs website at http://nhp.nris.state.mt.us/reports.asp as well as Montana Fish, Wildlife, and Parks Comprehensive Fish and Wildlife Conservation Strategy website at http://fwp.mt.gov/wildthings/cfwcs/swg/planning.html The document begins with taxonomic checklists for amphibians and reptiles that: (1) have been documented as native species; (2) are potentially present as native species; (3) have been documented as exotic species successfully reproducing in the state; (4) have been documented as successfully reproducing in the state but for which there is uncertainty about their status as native or exotic species; and (5) have been documented in the state but for which there is no evidence of successful reproduction. Presence and status ranks for amphibians and reptiles are then summarized for various land management regions in Montana and background information is provided as to why species were assigned these ranks and what the associated management implications are for each state, federal, or tribal agency. Status ranks are described for Global Ranks (G ranks) assigned to species by NatureServe and State Ranks (S ranks) assigned to species by the Montana Natural Heritage Program because they are often used by federal and state agencies when they are developing their own special status ranks for species they will give special protections or considerations in land use planning. Status ranks and summaries of distribution and/or site occupancy rates from recent amphibian inventory surveys are provided for: (1) Region 1 National Forests; (2) Bureau of Land Management Field Offices; (3) tribal reservations; (4) Fish, Wildlife, and Parks Regions; and (5) National Wildlife Refuges or refuge complexes. General habitat associations are then summarized in tables listing major habitat types and all of the amphibian and reptile species that are typically found in these habitats. Laws and regulations applicable to Montanas amphibians and reptiles are then summarized, including federal laws and regulations, tribal regulations, portions of Montana Code Annotated relevant to nongame and endangered species, and portions of Montana Code Annotated relevant to importation, introduction, and translocation of wildlife. A review of literature relevant to conservation of amphibians and reptiles includes sections on (1) ecological function and importance of amphibians and reptiles, (2) amphibian and reptile biology and disturbance regimes relevant to management, (3) risk factors relevant to the viability of amphibian and reptile populations including: (a) global amphibian declines; (b) timber harvest; (c) grazing; (d) fire and fire management activities; (e) nonindigenous species and their management; (f) road and trail development and on- and off-road vehicle use; (g) development and management of recreational facilities and water impoundments; (h) harvest and commerce; and (i) habitat fragmentation and metapopulation impacts. This review is currently somewhat biased toward amphibians, both because of the much higher recent concern over the status of amphibians and because this literature review drew from previous efforts focused on amphibians. Accounts for individual species then summarize what is known about the species distributition, taxonomy, maximum documented elevation, habitat use and natural history, and conservation status. Sections on identification of various life history stages and priority research and management issues are also included. Finally, an attempt was made to compile a complete bibliography of published and gray literature for each species in order to provide everyone easy access to this information. These accounts are intended to be updated on a regular basis in order to provide everyone access to the latest information. A contact list for members of the Montana Amphibian and Reptile Working Group is included in order to promote communication between agency biologists, resource managers, students, researchers, and anyone interested in the conservation of amphibians and reptiles in Montana. An overview of the statewide inventory and monitoring program for amphibians and reptiles provides background information on the sampling schemes used, methods used for surveys, and the survey forms used for a variety of amphibian inventory work. Watershed summaries for the lentic breeding amphibian and aquatic reptile surveys complete the current version of this report in order to provide resource managers easy access to this information. Georeferenced site photos associated with this inventory work have been posted on the Montana Natural Heritage Programs TRACKER website which can be accessed at: http://mtnhp.org It is recommended that users of this document first use the tables at the beginning of the document to identify management status, likelihood of a species presence in the area of interest, and the complement of species that are typically found in each general habitat type. Users should then examine individual species accounts in order gain a more thorough understanding of a species distribution, status, resource needs, factors that may pose a threat to population viability, and management actions that may mitigate these threats. Finally, users can review results of field surveys contained in individual watershed reports or see up-to-date distribution information for each species on the Montana Natural Heritage TRACKER website at: http://mtnhp.org

This book was released on 1999 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: During 1995 and 1998, a total of 110 site surveys for amphibians and reptiles were conducted by Montana Natural Heritage Program biologists in the Bureau of Land Management Miles City District (the former Billings, Big Dry, and Powder River Resource Areas) in eastern Montana. During the 1998 contract period, 102 site surveys were conducted (8 of these were nocturnal roadside call surveys, 94 were standard surveys) during April to July. All surveys were conducted by one individual. Surveys took from 5 to 180 minutes (mean = 58.5 min) and consisted of a thorough search of the wetland perimeter in combination with netting of near shore aquatic habitats for adults, eggs, larvae, and tadpoles. Sampling was done by hand and dipnet. At seeps, rocks and logs were overturned in and near wet areas to expose hidden individuals. In addition to site surveys, observations of road kills were recorded, as were fortuitous sightings by those conducting the surveys or other reliable individuals. Ten species (6 amphibian and 4 reptile) were detected within the Miles City District area during 1998 site surveys. Species included: Tiger Salamander (Ambystoma tigrinum), Woodhouse's Toad (Bufo woodhouseii), Great Plains Toad (Bufo cognatus), Western Chorus Frog (Pseudacris triseritata), Plains Spadefoot (Spea bombifrons), Northern Leopard Frog (Rana pipiens), Painted Turtle (Chrysemsy picta), Racer (Coluber constrictor), Plains Garter Snake (Thamnophis radix), and Common Garter Snake (Thamnophis sirtalis). Four reptile species encountered in 1998 other than on site surveys include Smooth Green Snake (Liochlorophis vernalis), Gopher Snake (Pituophis catenifer), Western Hognose Snake (Heterodon nasicus) and Western Rattlesnake (Crotalus viridis). In addition, Short-horned Lizard (Phrynosoma hernandezi), Sagebrush Lizard (Sceloporus graciousus) and Western Terrestrial Garter Snake (Thamnophis elegans) were reported from the Miles City District by other observers in 1998. In 1995, 3 species were detected during 8 site surveys in Carbon County: Tiger Salamander, Western Chorus Frog, and Plains Spadefoot. Short-horned Lizard, Sagebrush Lizard, Gopher Snake, and Western Rattlesnake were also encountered, but not during surveys. Of the 1998 surveys, 95.1% had one or more amphibian or reptile species present. Western Chorus Frog, Northern Leopard Frog, and Plains Garter Snake were the most frequently encountered species in 1998, being recorded on 67.6%, 61.7% and 22.3% respectively, of the site surveys. Species with records from the Miles City District area, but not encountered during the 1995 and 1998 surveys, include Bullfrog (Rana catesbeiana), Common Snapping Turtle (Chelydra serpentina), Spiny Softshell (Trionys spiniferus), and Milk Snake (Lampropeltis triangulum). Western Toad (Bufo boreas), Columbia Spotted Frog (Rana luteiventris), and Rubber Boa (Charina bottae), all with montane affinities, have been documented but are marginal to the Miles City District in the west. The Canadian Toad (Bufo hemiophrys), although recorded from the Miles City District area in 1966, is now considered historical (not reported in>30 years). Wood Frog (Rana sylvatica) might be documented eventually from the Miles City District area in the Big Horn Mountains of Big Horn County.

This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beginning in the late 1980s herpetologists began to realize that amphibians around the world had undergone, and were continuing to undergo, declines, extirpations, and extinctions. In most cases, detections of declines and determinations of the underlying causes has been hampered by a lack of available baseline information on distribution and status. This project was a cooperative effort to address these data deficiencies for amphibians and reptiles in Montana. Watersheds with greater than 30 percent federal or state land ownership were randomly selected for survey in each of 11 geographic strata. Visual encounter and dipnet surveys of all standing water bodies on public lands within these watersheds yielded watershed and site occupancy estimates as a measure of status. Occupancy estimates from this first-ever state-wide base level assessment can be more validly used for future comparisons with future status assessment, provided additional support for declines in Western Toad (Bufo boreas) and Northern Leopard Frog (Rana pipiens) populations in western Montana, and identified a variety of conservation issues of concern that can be addressed through management actions (e.g., clear evidence for negative impacts of fish and importance of maintaining natural disturbance regimes such as flooding, beaver, and fire). The information gathered during field inventories was combined with other existing information and used in maximum entropy modeling to predict state-wide distribution and habitat suitability for all of Montana's amphibians and reptiles. These models out performed GAP analysis models by simultaneously reducing the area predicted and omission error rates. Among other things, models identified scale dependent responses to environmental variables, potentially isolated populations in need of conservation efforts, and areas that are critical for maintaining landscape connectivity. In conjunction with field inventories, a state-wide assessment of the distribution of the pathogenic chytrid fungus (Batrachochytrium dendrobatidis) (Bd) was undertaken using PCR-based detection in skin swabs or tissue samples. Bd was found across Montana in 6 of the 9 species tested at a variety of elevations, habitats, and distances from human activities. The widespread presence of Bd highlights the need for additional studies and measures to prevent the spread of Bd and other novel pathogens.
