Jeff Ogden

Nova Scotia Provincial Forest Entomologist

A graduate (BSc) of Acadia University and (MSc) Mount Allison University, Jeff Ogden has worked in forest protection since 1993. Over those 29 years, his duties have varied from seasonal lab assistant to forest health specialist, collections curator and field entomologist. Jeff has been in his current role since the summer of 2021. His greatest accomplishments to date are a result of the strong professional relationships that he has formed with past and current forest health and regional staff as well as numerous collaborators over the years. These collaborations have resulted in the development and maintenance of a strong forest pest annual monitoring program, countless research projects on forest pests and insect biodiversity, and the curation of the provincial entomology collection.
