The focus of this thesis was to assess the response of bee communities to disturbance in fragmented oak savannahs. The study presents data that show that restoration of fragmented oak savannah habitats throughout Southern Ontario has a positive impact on bee communities. Bee species that were lost due to degradation can be restored. All oak savannah habitats that were chosen have a wide range of post-bum ages, and disturbance levels. Malaise traps were used to collect bees in three oak savannah habitats during the last 2 weeks in August from 1986 to 2006 in two provincial parks: Pinery and Turkey Point and Pterophylla native plant nursery. The results also show the importance of fire frequency on the spatial and temporal patterns of bee diversity and abundance in newly restored savannah habitat compared to older savannah habitat. Changes in bee communities were more detectable between guilds than using broad biodiversity analyses.
