| General Description |
Newly vegetated sandbar
|
| Vegetation Description |
In 1994 the vegetation cover was less than 3% and consisted primarily of seedlings of Salix interior, S. alaxensis, S. novae-angliae and Populus balsmifera and less than 1% cover of Equisetum arvense, J. articus, J. alpinus and Deschampsia caespitosa. Maximum willow height s were 60 cm while heights of balsam poplar were only 30 cm. By 1997 cover of balsam poplar seedlings and willows had increased to approximately 10% and herb cover, primarily Equisetum arvense and Juncus alpinus, to 4%. Maximum willow heights were 170 cm but average heights of both willows and poplars were 40 cm. In 1997 the site received severe flooding for several weeks in July and August which resulted in the accumulation of nearly a meter of silt, setting the vegetation back to nearly that of 1994.

| History |
In 1993 a large expanse (1km x 1km) of new sandbar was established as part of an island complex during a major shift in the channel of the Tanana River. In 1994 we established FP0A in the center of this area so that we could follow the succession from the first invasion by plants through to later stages of succession. We realized that there was a high likelyhood that the area would experience frequent severe flooding and that there was some chance that the entire area would return to river channel without vegetation development.
