The Purpose: Understanding ecosystem responses to atmospheric deposition requires the quantification of contaminants in the air. Wet deposition is being measured in precipitation and in through fall (wash-off passing though tree branches).

Results indicate that N and S deposition is 2-3 times higher in JP sites near the industrial zone compared to remote JP sites. N deposition in through fall is a lower estimate of total N deposition due to canopy N retention, but S in through fall is similar to total N deposition. Resins have been deployed at jack pine sites since May 2010.  Bear fencing was also installed in May 2010. An assessment of IER results relative to other air monitoring data was undertaken to determine if the relative levels are consistent with co-located measurements.  In early 2011, an assessment of the resin data will determine if the program should be expanded to additional Forest Health Monitoring locations.
