LTER/VCR005:
The purpose of this study is to compare (a) aboveground annual net
primary production, (b) belowground annual net primary production, and
(c) evapotranspiration of Spartina alterniflora along a transect
across VCR. Permanent sampling sites were established during the first
year on the mainland side near Brownsville, at a mid-bay island, and
on the back side of Hog Island. Additional sites may be added in
subsequent years. The objectives of the study are to compare primary
production along gradients of differing geomorphological,
hydrological, and geochemical conditions. Aboveground primary
production of marsh cordgrass (Spartina alterniflora) has been
established on a series of permanent plots. The methodology, developed
by James T. Morris at the North Inlet LTER site, utilizes
length-weight relationships of permanently marked plants. Sediment
pore-water chemistry and hydrology are being monitored at the same
sites.
