Anthropogenic pressures within the Lower Fraser River Valley are reducing the number of available nest and perching trees for large raptors across the south coast of British Columbia.
Additionally, large raptors have been increasing since bounties ended in the 1950’s, resulting increased numbers of human-raptor conflict.
David Hancock started monitoring Bald Eagles in the Fraser Valley in the 1960’s and continues to do so today with the support of The Hancock Wildlife Foundation. Over 400 known Bald Eagle nests are monitored across the Fraser Valley. These are checked annually and entered into our database.
Our nest mitigation began initially by requests to replace and reinforce existing Bald Eagle nests that were subject to fall apart or had been blown out of trees during wind storms.
The provision of artificial, alternative nest sites through the modification of existing trees and installation of platform towers has been undertaken since 2007. To date, the acceptance of our modified nest trees by Bald Eagles has been remarkably high and are often adopted only days after birds arrive back on territories after migration.
