This book was released on 2003 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes work conducted to initiate development of a habitat supply model (HSM) for mountain goats (Oreamnos americanus) that would be used to address management concerns for mountain goat populations potentially impacted by forest harvesting, particularly in those locations where goats use low-elevation mineral licks in areas with high timber supply value. The introduction reviews mountain goat ecology & management concerns in the Mackenzie Timber Supply Area of northern British Columbia and the objectives & applications of goat HSM in land use planning. Section 2 describes modelling activities and includes information on the modelling approach and the modelling tools used. The models developed are presented in section 3. These include four sub-models of management factors (covering ground disturbance, aerial disturbance, hunting, & predation) and four habitat models that focussed on habitat types considered most likely to be either limiting or important to mountain goat populations in the Mackenzie Timber Supply Area. Sections 4 & 5 present modelling results & their interpretation and information on procedures for model testing & validation. Appendices include an agenda & summary of HSM workshops conducted in February & March 2003 and results of trial application of the model to the Ospika River drainage.

This book was released on 2006 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Habitat Management Model (HMM) was prepared to evaluate the existing management strategies for heli-skiing operations located in the vicinity of confirmed and unconfirmed mountain goat habitat in northwestern British Columbia. The model is a three dimensional analysis incorporating a predictive habitat model, a viewshed analysis and a noise model simulation. The HMM analyzed the visual and audio impact of helicopter overflights on mountain goats within 500 m, 1000 m, 1500 m and 2000 m from confirmed and unconfirmed mountain goat habitat. The HMM for 1000 m and 1500 m found there was no change with the West flight path and minimal change (0.37%) in area) for the East flight path to disturbance levels HMM1 and HMM2. Management strategies developed by the Ministry of Water, Land and Air Protection Skeena Region (MWLAP Skeena Region 2004) and Last Frontier Heliskiing were analyzed within the context of the HMM.--P.2.

Book excerpt: Mountain goats have been among the least studied of North American ungulates, leaving wildlife managers with little information on which to base harvest strategies or conservation plans. This book offers the first comprehensive assessment of the ecology and behavior of mountain goats, setting forth the results of a remarkable 16-year longitudinal study of more than 300 marked individuals in a population in Alberta, Canada. The authors’ thorough, long-term study allowed them to draw important conclusions about mountain goat ecology—including individual reproductive strategies, population dynamics, and sensitivity to human disturbance—and to use those conclusions in offering guidance for developing effective conservation strategies. Chapters examine: -habitat use, vegetation quality, and seasonal movements -sexual segregation and social organization -individual variability in yearly and lifetime reproductive success of females -age- and sex-specific survival and dispersal -reproductive strategies and population dynamics -management and conservation of mountain goats The book also draws on the rich literature on long-term monitoring of marked ungulates to explore similarities and differences between mountain goats and other species, particularly bighorn sheep and ibex. By monitoring a marked population over a long period of time, researchers were able to document changes in sex-age structure and identify factors driving population dynamics. Because it explores the links between individual life-history strategy and population dynamics in a natural setting, Mountain Goats will be an invaluable resource for wildlife managers, researchers in ecology and animal behavior, conservationists, population biologists, and anyone concerned with the ecology and management of natural populations, especially in alpine environments.

Book excerpt: A 70-90% decline in mountain goat (Oreamnos americanus) populations in Washington State over the past few decades has spurred the need for an improved understanding of seasonal goat-habitat relationships. Habitat use data have been collected from 46 radio-collared mountain goats across their native range in Washington State. Using Geographical Information Systems (GIS), I explored relationships between use and availability of habitat. To overcome issues of autocorrelation, I compared actual mountain goat paths with available paths of matched identical spatial topology and used multi-scale path analysis to explore various ecologically informed relationships between landscape structure and the movements of mountain goats at the home range scale. I extracted used and available (randomized) paths at 4 scales of analysis using square extraction windows of 0.06, 4.4, 15.2, and 56.2 ha that were centered on each point along the path. Matched case logistic regression allowed me to determine the spatially and temporally explicit scales that were the strongest predictors of seasonal and year-round mountain goat habitat from a suite of predictor variables. I found that for year-round habitat, mountain goats chose both abiotic and biotic components of their landscape including; parkland, areas of high solar loading, terrain that is rugged, and terrain that allows escape from predators. This analysis represents one of the most extensive landscape-level habitat relationship studies conducted on mountain goats. Additionally, my methodological approach is applicable to other species-habitat association analyses.

Available in PDF, EPUB and Kindle. Book excerpt: The mountain goat is an apparently secure species that occurs through the mountainous regions of British Columbia. This assessment establishes the risk to mountain goat populations in 33 landscape units in the North Coast Land & Resource Management Plan area. The risk assessment uses static & temporal data within a standardized framework to predict the level of risk of maintaining the base-case circumstances. Much of the assessment relies on the interpretive mapping of winter range, the primary factor at risk with mountain goats. Winter range mapping was developed using a two-tier approach considering known & suspected patterns in sub-regional & stand-level winter habitat selection. Risk is then assessed using three indicators: direct impact on winter range through reduction of forest cover; relative increase in access-associated disturbance; and population fragility. The indicators are run through a Bayesian relief network to provide risk values for each landscape unit with levels of uncertainties. Possible options for mitigating the impact of forestry practices & human access on goat winter range are briefly discussed.

This book was released on 2015 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-native species can have adverse impacts on native species; however, coexistence may be possible if their ecological niches minimally overlap. Fine spatial scale information is needed to understand these niches but can be challenging to obtain for rare, imperfectly detected species inhabiting difficult to survey landscapes. Non-native mountain goats (Oreamnos americanus) in the greater Yellowstone area (GYA) are such a species and have substantial potential to expand in distribution and occupy similar habitats to native Rocky Mountain bighorn sheep (Ovis canadensis canadensis). To understand the niche and potential for expansion of mountain goats in the GYA, this study used a unique, fine spatial scale method to collect detection-nondetection data from two study areas with established mountain goat populations over three summer seasons (2011-2013). Relationships between scale-specific habitat covariates and mountain goat selection were evaluated using a single-species, single-season occupancy analysis to model occupancy and detection probabilities based on 505 mountain goat detections from 53,098 surveyed sampling units. Habitat selection was most strongly associated with terrain covariates, including mean slope and slope variance, at a spatial scale of 500 x 500 m, and canopy cover, heat load, and normalized difference vegetation index at a spatial scale of 100 x 100 m. These results provide new insight into multi-scale patterns of mountain goat habitat selection, as well as evidence that mean slope and slope variance are superior terrain covariates to distance to escape terrain that has dominated published mountain goat habitat models. The model predicted 10,745 km 2 of suitable habitat within the GYA, of which 57% is currently un-colonized. Throughout the GYA, suitable habitat appears to generally overlap extensively with areas occupied by bighorn sheep. I also estimated the GYA may have the potential to support 5,372-8,918 mountain goats when all predicted habitat is occupied, or approximately 2.5-4.2 times the most recent abundance estimate of 2,104.

This book was released on 2015 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-native species can have adverse impacts on native species. Predicting the potential extent of distributional expansion and abundance of an invading non-native species can inform appropriate conservation and management actions. Non-native mountain goats (Oreamnos americanus) in the greater Yellowstone area (GYA) have substantial potential to occupy similar habitats to native Rocky Mountain bighorn sheep (Ovis canadensis canadensis). To understand the potential for expansion of mountain goats in the GYA, this study evaluated detection-nondetection data derived from ground-based occupancy surveys of viewsheds partitioned into a grid of 100 ? 100 m sampling units. Surveys were conducted over three summer seasons (2011?2013) in two study areas with well-established mountain goat populations. Relationships between scale-specific habitat covariates and mountain goat selection were evaluated to model occupancy and detection probabilities based on mountain goat detections in 505 of the 53,098 sampling units surveyed. Habitat selection was most strongly associated with terrain covariates, including mean slope and slope variance, at a spatial scale of 500 ? 500 m, and canopy cover, heat load, and normalized difference vegetation index at a spatial scale of 100 ? 100 m. These results provide new insight into multi-scale patterns of mountain goat habitat selection, as well as evidence that mean slope and slope variance are more informative terrain covariates than distance to escape terrain, which has been commonly used in published mountain goat habitat models. The model predicted 9,035 km2 of suitable habitat within the GYA, of which 57% is currently un-colonized. Seventy-five percent of all bighorn observations recorded in the GYA fall within predicted suitable mountain goat habitat. We also estimated that the GYA might have the potential to support 5,331?8,854 mountain goats when all predicted habitat is occupied, or approximately 2.5?4.2 times the most recent abundance estimate of 2,354.
