1986 to 2005 Urban Forest Stewardship Initiative Tree Cover and Impervious Surface Report

On behalf of the Urban Forest Stewardship Initiative, HAT used GIS technology and orthophotography to map changes in tree cover and impervious surface areas from Sooke to Sidney region. CITYgreen software was used to calculate the monetary value trees in our region provide in green ecosystem services, such as stormwater retention, and carbon sequestration.  The full report and an Executive Summary are available. Data layers are avialable on request.
