Intensive snow survey no. 4

Active forest thinning of cedar stands at Takiya River

This winter we are undertaking intensive snow surveys from the season of peak snow accumulation to the spring melt-off. Our objective is to investigate the influence of forest canopy characteristics on snow accumulation and melt, and in particular to compare varying levels of thinning in cedar stands.

Below you can see a summary of the results from the first four surveys. Melt season is now well underway in most study plots, although surprisingly it seems the forest opening plot is still maintaining the peak level for snow water equivalent (SWE). The larch plot has been surveyed during more than 20 years, and this year shows a peak value of SWE which is the second highest on record.
