Title Abstract
Eriophorum vaginatum leaf length 2015-2017 from 2014 common gardens established at Toolik Lake, Coldfoot, and Sagwon - Alaska
Data on Eriophorum vaginatum leaf length collected from common gardens established at Toolik Lake, Coldfoot, and Sagwon in 2014 with tussocks from  Coldfoot, Toolik Lake, and Sagwon. Data collected during the growing seasons of 2015, 2016, and 2017
Litter decomposition from 2014 reciprocal transplant garden Toolik Lake, Coldfoot, and Sagwon, Alaska 2016
Data on litter decomposition of Eriophorum vaginatum leaves collected at Toolik Lake, Coldfoot, and Sagwon and distributed to all three sites. Litter bags from the three populations were deployed at CF (8/26/15), TL (8/24/16) and SG (8/25/16) sites approximately 40 meter away from the main transplant gardens (east of CF, east of TL and west of SG) into 5 blocks with 4 intended harvests at each plots.
Normalized difference vegetation index and Leaf area index of tussocks from reciprocal transplant gardens at Toolik Lake, Coldfoot, and Sagwon, Alaska 2016
Normalized difference vegetation index (NDVI)  and Leaf area index (LAI) data from tussocks in the reciprocal transplant gardens at Toolik Lake, Coldfoot, and Sagwon in 2016.

Data on Eriophorum vaginatum leaf length collected from a common garden established at Toolik Lake in 2011 with tussocks from No Name Creek, Coldfoot, Eagle Creek, Toolik Lake, Sagwon, and Prudhoe Bay. Data collected during the growing seasons of 2015 and 2016. Results published in Parker, T. C., J. Tang, M. B. Clark, M. M. Moody, and N. Fetcher. 2017.

Title Abstract
Effects of shading on tundra vegetation senescence at Toolik Lake, Coldfoot, Sagwon - Alaska 2016
Data on the effects of shading tundra vegetation from the sun when it is low in on the horizon in the north. If light quality was altered through shading, phenology might be affected. Senescence (color change) was measured for the common tundra species.
Effects of 2015 experimental burn on Eriophorum vaginatum at Toolik Lake Field Station, Alaska 2016
This was an experimental burn conducted in the summer of 2015 to provide sites for an experiment to see whether seeds of Eriophorum vaginatum from different ecotypes could establish in recently burned areas.  It consisted of ten 2 meter X 2 meter plots along with a similar number of control plots. There was little seedling establishment but other data have been collected on the plots.

Terrestrial Plant Phenological and Growth Data
Title Abstract
Phenological stages of evergeen plants were observed at a long term experimental moist tussock tundra site (Arctic LTER) 1996 near Toolik Lake, AK.
Phenological stages of evergeen plants were observed at a long term experimental moist acidic tussock tundra (Arctic LTER) in 1996 near Toolik Lake, AK. Also, ITEX maximum growth measurements were recorded on August 19th (moist tussock tundra). Experimental treatments at each site included factorial NxP, greenhouse and shadehouse and were begun in 1989. See 96gsphdc and 96gsphsg for phenological data on deciduous and sedge species.
