|Abstract:||These data were collected in July 1993 for tussocks transplanted in 1980-82 in a reciprocal transplant experiment and harvested in 2011. Important variables are garden name, source population, the number of green leaves, and the length of the longest leaf.|

|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.||The garden is 120 m north of the Dalton Highway on the east side of the bridge. It consists of 2 rows of stakes.||The garden is 60 m north of the road to the Galbraith Lake Airport.||The garden is 470 m east of the Dalton Highway on the downhill side of the old pad for the Old Man construction camp.|

|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 1993. For a haphazardly chosen subsample of tillers ( n = 3) on each tussock, the total number of green leaves was counted and the length of the longest leaf was measured from the top of the sheath. Old leaves that were initiated the previous year were identified by a dark band with dead tissue above it, whereas new leaves had no such band. A tiller size index was calculated by multiplying the length of the longest leaf by the total number of green leaves (usually 2, 3 or 4). This tiller index is highly correlated with tiller mass (Shaver, Fetcher & Chapin 1986).
In this census, we also measured tiller size index at two additional gardens, Kuparik (K), Galbraith (GAL), and for three additional populations Kuparik (K), Galbraith (G), and Old Man (OM). In addition, we measured number of green leaves and length of the longest leaf for 10 untransplanted tussocks at each garden. These are designated by CONTROL.
