Plant biomass, production and chemistry measurements near Toolik Lake, Alaska for moist tundra, wet sedge, tall shrub, and dry heath. Some harvests include total nitrogen and phosphorus.

Terrestrial Biomass
Abstract
Laura Gough, 2009 Above ground plant and below ground stem biomass in the Arctic LTER moist acidic tussock tundra experimental plots, 2006, Toolik Lake, Alaska. 10.6073/pasta/5587a6f1bfc4f359c011139b2977d842
Above ground plant and below ground stem biomass, percent nitrogen, and percent carbon were measured in the Arctic LTER moist acidic tundra experimental plots. Treatments included control, and nitrogen and phosphorus amended plots for 10 years, and exclosure plots with and without added nitrogen and phosphorus.
Laura Gough, 2009 Above ground plant and below ground stem biomass in the Arctic LTER dry heath tundra experimental plots, 2006, Toolik Lake, Alaska. 10.6073/pasta/447aec542efb8fd505b85f90c35ea47e
Above ground plant and below ground stem biomass, percent nitrogen, and percent carbon were measured in the Arctic LTER dry heath tundra experimental plots. Treatments included control, and nitrogen and phosphorus amended plots for 10 years, and exclosure plots with and without added nitrogen and phosphorus.
Gaius Shaver, 2001 Plant biomass in moist acidic tussock tundra experimental small mammal exclosures, 1999 Arctic LTER Toolik, Alaska.. 10.6073/pasta/3180bd090124c3a0d7a498e95685dfac
Above ground plant and below ground stem biomass was measured in Arctic LTER tussock tundra experimental small mammal exclosures. Treatments included Control, Nitrogen plus Phosphorus with both fenced and unfenced plots. In addition a moist non-acidic tussock tundra site was harvested. Leaf areas were also measured for each quadrat but are in a separate file.
Gaius Shaver, 2005 Above ground plant and below ground stem biomass in the Arctic LTER acidic tussock tundra experimental plots, 2002, Toolik Lake, Alaska.. 10.6073/pasta/b227fa1d98ed466ea5fc3816ef5c8ba2
Above ground plant and below ground stem biomass was measured in the Arctic LTER acidic tussock tundra experimental plots. Treatments included control, nitrogen plus phosphorus amended plots for either 6 or 13 years and vole exclosure plots with or without amends of nitrogen and phosphorus.
Gaius Shaver, 2002 Plant leaf area in Arctic LTER tussock tundra experimental small mammal exclosures.. 10.6073/pasta/ad59eb7b05e4a22138a4d4c27b56f03b
Leaf areas were measured on quadrats harvested in Arctic LTER tussock tundra experimental small mammal exclosures. Treatments included Control, Nitrogen plus Phosphorus with both fenced and unfenced plots. In addition a moist non-acidic tussock tundra site was harvested. Biomass was also measured for each quadrat but is in a separate file.
Terrestrial Plant Communities and Plant Species List
Abstract
Laura Gough, 2019 Relative percent cover of plant species for years 2012-2017 in the Arctic Long-term Ecological Research (ARC-LTER) 1989 moist acidic tundra (MAT89) experimental plots, Toolik Field Station, Alaska. . 10.6073/pasta/f31def760db3f8e6cfee5fee07cc693e
Relative percent cover of plant species was measured in ARC-LTER 1989 moist acidic tundra experimental plots. Treatments include Control (CT), Nitrogen Phosphorus (NP), Nitrogen (N), Phosphorus (P), and Greenhouse Control (GHCT). In 1996 on unassigned plots, an experiment that manipulate herbivory presence and nutrients was started. Treatments include Control Unfenced (NFCT), Nitrogen Phosphorus Unfenced (NFNP), and Small Fenced Control (CTSF). Not all treatments were measured each year.
