Plant primary production on Herschel Island

We sample the net primary production (NPP) of plants in 2 mesic communities (Dryas-Salix heath and Eriophorum-Salix tundra), and one hydric community (Carex-Salix meadow) on Herschel Island. In 2007 this work was limited to NPP for graminoid species in these communities, but it was expand to cover a...

Description
Summary:We sample the net primary production (NPP) of plants in 2 mesic communities (Dryas-Salix heath and Eriophorum-Salix tundra), and one hydric community (Carex-Salix meadow) on Herschel Island. In 2007 this work was limited to NPP for graminoid species in these communities, but it was expand to cover all species since 2008. In each communities we established from 4 to 12 herbivore exclosures (2 m x 2 m x 80 cm high) made of chicken wire, so as to measure the potential impacts of herbivory on plant productivity in the future. NPP is estimated with 20 cm x 50 cm clip plots at peak growth (early August). All live above-ground biomass is cut, sorted out by species and weighed dry. ** If data are downloaded and used for analyses, it would greatly be appreciate that the principal investigator that generated the dataset be informed. : Purpose: Monitoring of tundra plant community primary production : Summary: Not Applicable
