Habitat selection and behavioural strategies of Stone's sheep in northern British Columbia.

Influence of prescribed fire on Stone's sheep and Rocky Mountain elk: Forage characteristics and resource separation.

“…The species o f vegetation we identified were similar to the plant communities described by Luckhurst (1973) and Walker (2005) in the same area. Communities established after a disturbance are mostly composed o f the same pool o f species present prior to the disturbance (Vandermeer et al 1995, Hart 2009).…”

“…Additionally, fall bums are typically larger and more intense (Holl et al 2012). In northeastern BC, the highest use of burned areas by ungulates is in winter (Peck and Peek 1991, Walker 2005, Gillingham and Parker 2008a, this study) and a fall bum would reduce access to forage on those areas. of shrub cover.…”

“…My research focused on the influence of bums on elk and Stone's sheep. Major elkwintering areas are associated with bums (Peck 1987, Parker and) and Stone's sheep often use burned areas in late winter and early spring (Seip 1983, Walker 2005. As elk populations expand in northeastern BC (Shackleton 2013), there is concern that the management activities of prescribed burning may promote competition between elk and Stone's sheep.…”

“…In northern BC, where the growing season is short, plant phenology plays an important role in the selection o f foraging sites for Stone's sheep and elk (Seip 1983, Peck 1987, Walker 2005. As part o f the PeaceLiard Prescribed Bum Program, 4 prescribed bums were implemented for this study in the spring o f 2010.…”

Integrating production functions of timber, forage, and cattle to achieve sustainable resource management.

“…Over the last decade, many species of terrestrial wildlife have successfully been fitted with GPS collars (Figure 1.1). Some examples are moose (Rodgers and Anson 1994;Rempel et al 1995;Moen et al 1996aMoen et al , 1996bDussault et al 1999;Girard et al 2002), deer (Blanc and Brelurut 1997;Merrill et al 1998;Bowman et al 2000), elk (Biggs et al 2001), caribou (Johnson et al 2002a(Johnson et al , 2002b, and stone sheep (Walker 2005). GPS tracking collars have also been incorporated in research on the ecology and management of grazing systems using sheep (Rutter et al 1997;Hulbert et al 1998) and cattle (Turner et al 2000;Ganskopp 2001;Ungar et al 2005).…”
