1st Case study – A multi-species conservation program
Problem – Wildlife species inhabiting mature and old forests across large expanses are affected by large-scale logging.
Assessment – The loss of large expanses of late-seral forests causes the extirpation of wildlife populations.
Solution – Alpha Wildlife used the concept of indicator species to develop a multi-species forest management plan in central interior British Columbia. With this approach, the degree of preference that some species show for specific habitats was used to identify late-successional stands that have greater potential for biodiversity conservation.

2nd Case study – Landscape management for the boreal woodland caribou
Problem – The primary factor causing extinctions are habitat loss and habitat fragmentation.
Assessment – In Western Alberta, limited information exists on boreal woodland caribou.
Solution – Alpha Wildlife conducted a 2-year study of caribou late-winter habitat to identify landscapes that should be managed to conserve functional habitats. Thereafter, a landscape management plan was developed with high-, medium- and low-quality habitat zones, and connectivity corridors.
