We removed sediment cores from coves, points, and straights, and from planted and unplanted regions of those locations along the shoreline of L-Lake, a created and planted cooling reservoir, to determine whether their seedbank composition differs. Sets of cores were taken from depths up to one meter, from the waterline, and from one meter above water, to determine the effects of hydrology on seedbank composition. Cores were split into unstratified samples that were kept at 5 C for 120 days before allowing germination in the greenhouse. As they emerged from cores, seedlings were identified or transplanted and left to flower for later identification.
Results show that water depth is the primary influence on seedbank composition.
Points, coves, and straights did not differ in species richness or number of germinable seeds.
