“…Location success is related to differences in overstory vegetation (Rempel et al 1995;Moen et al 1996;Dussault et al 1999;D'Eon et al 2002), topography (D'Eon et al 2002), and animal behaviour (Edenius 1997;Bowman et al 2000;Moen et al 2001). The GPS locations likely underestimated the use of forest stands with higher crown closures and stem densities.…”

“…Location accuracy is inversely related to dilution of precision values, and 3D locations have a higher probability of being more accurate than 2D locations (Trimble Navigation Ltd 1994*; British Columbia Ministry of Environment, Lands and Parks 1995*; Johnson 2000). Whenever GPS location success is <100%, then GPS locations likely represent a biased sample of habitat use because location success is affected by factors like tree density, canopy cover and topography (Rempel et al 1995;Moen et al 1996;Dussault et al 1999;D'Eon et al 2002). This was especially important in our study because we were interested in documenting forest use by goats.…”

Poole, Kim G., and Douglas C. Heard. 2003. Seasonal habitat use and movements of Mountain Goats, Oreamnos americanus, in east-central British Columbia. Canadian Field-Naturalist 117(4): 565-576.To identify the potential for adverse effects of forest development on Mountain Goats (Oreamnos americanus), we documented the patterns of forest use by goats and the factors influencing goat habitat use. We used a combination of 15 very high frequency (VHF) and six global positioning system (GPS) radiocollars to document the distribution and movements of 21 (15 female, 6 male) goats from 1997 to 1999 in the mountains surrounding the Robson Valley in east-central British Columbia. Because canopy closure reduces the likelihood that a GPS receiver will obtain a location fix, we estimated that GPS collars underrepresented forest use by about 23%. Three goats used separate winter and summer ranges separated by 8-13 km, while most simply exhibited seasonal shifts in elevation. In winter, goats were more often at lower elevations, in commercial forest stands, on southerly aspects, and moved less each hour and over the course of the winter. Goat use declined in areas >500 m from escape terrain and goats were found lower in elevation from evening to dawn compared to daylight hours. Collared goats used high elevation licks, which were either within their home range, or in two cases, 6 and 14 km from their typical home range. We documented use of known mid-elevation mineral licks by three collared goats, but no use of known low elevation (valley bottom and lower slopes) mineral licks. Robson Valley goats appeared to be at relatively low risk from disturbances related to logging, because although forest use was documented during winter, it occurred primarily on high elevation, steep slopes where trees are currently of low commercial value, and goats made little use of low elevation mineral licks. We recommend that in this area a forested buffer of 500 m around cliffs be left to reduce the possibility of adverse effects on goats especially, on southerly aspects above 1300 m.Key Words: Mountain Goats, Oreamnos americanus, British Columbia, distribution, habitat use, home range, mineral licks, movements.the Columbia Mountains to the southwest. Goats were monitored up to 28 km from the main valley. Elevations ranged from 715 m at the northwest end of the valley bottom to surrounding peaks that were generally between 2600 and 3250 m. Shackleton (1999) rated the relative density of goats in the area as moderate. Within a 2700-km 2 census zone (above 1675 m) encompassing the study animals, the goat density was estimated at 0.8 goats/km 2 (Poole et al. 2000). Climate varied with elevation, with a general increase in precipitation and decline in temperature with increasing elevation. Mean July and January temperatures for Valemount, located at 797 m in the centre of the study area, were 15.8 and -11.0°C, respectively, with an average annual precipitation of 503 mm, 180 mm of which fall as snow (Environment Canada climate normals, unpublished...

“…However, determination of core areas within a range requires the construction of density functions with sufficient location information to provide robust estimates of use. The use of GPS in automated telemetry has been thoroughly studied to determine the appropriateness of conducting animal movement research (Rodgers & Anson, 1994;Moen et al, 1996;Rodgers et al, 1996;Moen et al, 1997;Dussault et al, 2001). GPS collars are capable of collecting multiple daily fixes over an extended time and provide an unbiased and precise estimate of animal locations.…”

Abstract:The Owl Lake boreal woodland caribou population is the most southerly population in Manitoba. It is provincially ranked as a High Conservation Concern Population. Forestry operations exist in the area and there are plans for further forest harvest and renewal. The Happy Lake logging road is the only main access through the Owl Lake winter range. This logging road is currently closed to the public and access is limited to forestry operations during specific times of the year. An integrated forestry/caribou management strategy for the area provides for the maintenance of minimum areas of functional habitat. Habitat quality along the road was compared to habitat quality in the winter core use areas, within the winter range and outside the winter range. To evaluate the extent of functional habitat near the road, we conducted animal location and movement analysis using GPS data collected from January 2002 to March 2006. Habitat quality in the winter range, core use areas and along the road were assessed and found to be similar. Analysis of caribou locations and movement illustrate less use of high quality habitat adjacent to the Happy Lake Road. Loss of functional habitat is suggested to occur within 1 kilometre of the road. This potential loss of functional habitat should be incorporated into integrated forestry and caribou conservation strategies. Road management is recommended to minimize the potential sensory disturbance and associated impacts of all weather access on boreal woodland caribou.

“…Dataset that had GPS errors like missing coordinates were removed from the dataset before analysis. The causes of GPS errors are: Temporal malfunction of the GPS collars (Gala, 2014), canopy cover (Jiang et al, 2008;Sager-Fradkin et al, 2007;Heard et al, 2008), topography (terrain and slope; Hebblewhite et al, 2007;Frair et al, 2004) and collar orientation (Sager-Fradkin et al, 2007;Heard et al, 2008;Moen et al, 1996;Frair et al, 2010). The data available for analysis after screening ranged between 58 and 92% (Table 2), which is within acceptable range to characterize wildlife movement patterns and make sound inference (Frair et al, 2010).…”

The African elephant (Loxodonta africana) require vast areas to meet their survival needs such as food, mates, water, resting sites, and look up positions; the area referred to as home range. We collared 9 bull and 3 female elephants using satellite-linked Geographic Positioning System (GPS) collars in February 2013. Their movements were monitored up to April 2016 in the wider Amboseli landscape. We estimated their home ranges using 100% minimum convex polygon (MCP) and 95% Fixed Kernel Density Estimator (KDE) methods. A total of 48,852 GPS points were used representing 77% of the expected GPS points. This study revealed that bulls had a larger total home range size (MCP = 32,110 km²; KDE = 3,170 km² compared to females (MCP = 10,515 km²; KDE = 3,070 km²). The 95% confidence interval of the monthly range (95% KDE) for all elephants was 6,130 to 7,025 km² with the minimum and maximum range being 5,200 and 7,790 km² respectively. Females had smaller home ranges during the dry and wet season (MCP: dry = 2,974 km²; wet = 1,828 km²; KDE: dry = 2,810 km²; wet = 3,070 km²) than bulls (MCP: dry = 3,312 km²; wet = 13,288 km²; KDE: dry = 2,960 km²; wet = 3,720 km²). The variations of the elephant home range could have been influenced by an interaction of factors including rainfall, human disturbances and land use (e.g., farms, settlements, road network, and fences), water availability, bush cover, food availability, and tracking period. The most important areas that had key habitats for elephants were scattered throughout the Kenya/Tanzania borderland. The Amboseli-TsavoMagadi-Natron-West Kilimanjaro elephant population roams within specific areas of the landscape. Trans-boundary efforts should be enhanced to ensure sound management of the elephant-habitatpeople interface for continued well-being of the elephant population.
