Populations of Microtus oregoni were livetrapped from 1971 to 1974 in old field and grassland habitats at the University of British Columbia Research Forest, Maple Ridge, B.C. Forest (1974–1978) and shrub (1975–1980) habitats were also sampled intensively. An additional population was livetrapped (1971–1974) in abandoned grassland near Ladner, B.C. Microtus oregoni exhibited a 3–4 year cyclic fluctuation in abundance in the old field and shrub habitats. Maximum density (72 voles/ha) was recorded on the old field grid which was optimum habitat for this species. Winter breeding and a long reproductive period prior to the peak year, and larger body size during the peak than in other phases of the cycle were characteristic features of the old field population. This vole species did not have a multiannual cycle in habitats where the competitor, M. townsendii, was present. Oregon voles were 3–4 g heavier at the Research Forest than at the Ladner study area. Female voles were more prevalent than males in all populations.

Purpose – Universities can provide a leadership role to develop and mobilize knowledge to meet societal needs. In fulfilling this mission, universities can also serve as agents of sustainable development on campus and in communities they serve. The purpose of this article is to describe the drivers that have advanced the University of British Columbia Okanagan campus' operational and academic sustainability objectives; the initiatives and partnerships developed on campus and in the community in response to these drivers; and the outcomes and lessons learned. Design/methodology/approach – This article summarizes the experience of the University of British Columbia Okanagan campus in leveraging key drivers to develop sustainability initiatives and partnerships for greater operational efficiencies, cost savings, environmental stewardship and applied research. The university's leadership commitment to sustainability, economic opportunities and provincial legislative requirements are among the drivers discussed. This paper also provides an innovative partnership framework to support sustainable community development. Findings – Drivers of sustainability in higher education can contribute to the development of sustainability initiatives and partnerships that benefit institutions and communities and achieve operational and academic sustainability mandates. Practical implications – This article provides information that can be applied by institutions of higher education to advance sustainability within the context of current economic conditions and societal needs. Originality/value – The experience of the campus and the partnership framework presented in this paper is original. The framework provides a mechanism to engage students, faculty and the community in sustainable community development research. Key insights from multiple perspectives and lessons learned are shared.
