Monster Seminar JAM - Riparian Vegetation Dynamics in Space and Time: Can We Distinguish Natural and Anthropogenic Sources of Variability Over Broader Scales? NOTE: Location change

Dr. Sarah E. Gergel, Department of Forest Sciences and Centre for Applied Conservation Research, University of British Columbia.

Long Description:
More Information:
Riparian zones are inherently quite dynamic through time and exceptionally challenging to map across landscapes. Thus, characterizing natural levels of variability in their form and function over large areas remains a challenge. This is especially critical as riparian areas provide unique watershed functions and habitats but have also been preferentially degraded and historically over-utilized by humans due to their high productivity. Using watersheds in coastal British Columbia, I present research using old historical aerial photographs combined with historic logging records to examine the extent of human impacts on riparian zones in ways that have not been systematically documented. I also present research with a developing new technology, Quickbird high-spatial resolution satellite imagery, to document changes in riparian zones and prioritize areas for riparian restoration. These approaches represent useful tools for capturing the variability in these systems across broader spatial scales and longer time frames than is usually attempted.
