Alaskan Peatland Experiment: Community structure and productivity data for 2007-2010 II - Species Abundance

This dataset contains abundance for vascular and non vascular plants at the Alaska Peatland Experiment in 2007 and 2009. Two peatland types are included, a bog site and a fen site. Within the fen site a water table manipulation has been ongiong since 2005, with control, lowered and raised water table treatment plots. Measurements collected in 2007 included quadrats passively warmed using open top chamebr (OTC), although these quadrats were not measured in 2009. Data at the bog was measured in 2009, and plots include an area established within the lowland black spruce permafrost plateau (permafrost), and two plots established within collapse scars embedded within the plateau. One collapse scar formed ~ 45 years ago (old collapse) and the other formed ~ 25 years ago based upon aerial photography provided by the BCEF LTER. The data provided in this data set can be sorted by year, site and plot, in addition to warming treatment.
