Group: Summary

   This data set contains active layer data collected for the Toolik Snowfence 
   Experiment from 1994 to 2002. The Toolik Snowfence Experiment (part of the 
   International Tundra Experiment network) examines the short- and long-term 
   effects of increased snow depth (shortened growing season) and increased 
   summer temperature on arctic tundra vegetation. The goal of this project is to 
   assess potential changes in tundra plant communities in response to global 
   climate change.

   The research project was funded by the following Arctic System Sciences 
   (ARCSS) Program grants:

   1994 - 1998: OPP-9400083 -- ITEX / Comparative Responses of Moist and Dry 
   Arctic Tundra to Altered Snow and Temperature Regimes

   1999 - 2003: OPP-9907127 -- ITEX / Collaborative Research: Species Responses 
   to Changes in Climate Across Arctic Gradients Using the North America ITEX 
   Network (NATEX): Influences On Community and Ecosystem Processes

   1999 - 2003: OPP-9996383 -- ITEX / Comparative Responses of Moist and Dry 
   Arctic Tundra to Altered Snow and Temperature Regimes
