Abstract: These data were collected in July 2010 for tussocks transplanted in 1980-82 in a reciprocal transplant experiment and harvested in 2011. Important variables are garden name, source population, and whether the tussocks were alive in 1983,1993,2009, and 2010.

Geographic Description Eagle Creek Tussock Tundra Site on hillside above Eagle Creek at Mile 101 of the Steece Highway; garden is about 500 m upslope from an old berm created by bulldozer. Coordinates are approximate. Coordinates and elevation for all sites are from Google Earth. The garden is in the middle of giant tussocks 100 m north and 165 m west of the bridge that crosses No Name Creek on the Dalton Highway. Access is easier by going along No Creek for 165 m and then heading north. The garden is 100 m north of the edge of the forest and 190 m east of the Dalton Highway. The garden is in the complex of "historic sites" at Toolik Lake. The garden is 50 m north of the upper parking area at the Sagwon Overlook pulloff. Site fomerly known as MS 127. The garden is 1.5 km west of the Kuparik Bridge and 420 m north of the road on the east bank of a stream. Note: Permission from BP and oil field safety training required to access this site.

Organisms studied Eriophorum vaginatum
Methods:In 1980-1982, six transplant gardens were established along a latitudinal gradient in interior Alaska from Eagle Creek, AK, in the south to Prudhoe Bay, AK, in the north (Shaver et al. 1986) .Three sites, Toolik Lake (TL), Sagwon (SAG), and Prudhoe Bay (PB) are north of the continental divide and the remaining three, Eagle Creek (EC), No Name Creek (NN), and Coldfoot (CF), are south of the continental divide. Each garden consisted of 10 individual tussocks transplanted back to their home-site, as well as 10 individuals from each of the other transplant sites (n = 10; 6 populations x 6 sites x 10 replicates = 360 total individuals).

All gardens were censused in 1983, 1993, and 2010. All gardens except Prudhoe Bay were censused in 2009. At each census, tussocks were counted as alive if there was at least one surviving tiller (Bennington et al. 2012)
