Sampling Map for E052
1988: Clipped in the SW corner of each plot, 10cm x 1m
1989: Clipped at 1m in from the right side.
1990: First quadrat was clipped at 1m in from the SW corner of each
plot. Each subsequent quadrat was 30cm N from and parallel to the previous
quadrat. Vegetation was sampled on May 3, May 22, June 15, July 3,
July 24, August 23, September 24 and November 1.
Vegetation species composition of all plots was measured on August
22, along a transect that ran diagonally across each plot. Two
quadrats, each 0.5 x 1m, were placed along the transect, each 1.5m from one
end. The cover of each species was recorded using Daubenmire's scale of
six classes. Root biomass was measured in each plot on May 3 and August
23
by taking four soil cores (each 3cm diameter, 10cm deep), evenly
spaced along a transect 1m inside the west edge of each plot, and pooling them. The above-ground parts of transplants were harvested during 10-14 Sept. ,
sorted to dead pieces, flowering tillers and other live portions. All
above ground plant material, live and dead, within 15cm of each transplant
grown with all neighbors was harvested immediately after the transplant
was harvested.
1991: Above-ground biomass was measured by clipping all above-ground
plant material within a 10cm x 100cm quadrat in each plot during August
12-16.
Four cores were also taken from each plot, combined and rinsed for root
biomass. These cores were taken along a transect 1m inside the west
edge of each plot.
Species composition of all plots was measured on August 13-14 along
a transect that ran diagonally across each plot. Two quadrats, each
0.5 x 1m, were placed along the transect, each 1.5m from one end. The
cover of each species was recorded using Daubenmire's scale of six classes
(Mueller-Dombois and Ellenberg 1974).
Transplants were harvested during September 9-12 by removing the
tubes which contained the transplants. Transplant and neighbor biomass
were determined.
1993: Starting at the SE corner, we measured 2m north and 1m west.
Then, sample was clipped in a quadrat 1m long and 10cm wide running west
from their point. (See sheet for 1993).
In 1988, samples were sorted to live and dead. In 1989, samples were sorted to live leaves, stems and flowers, and dead. In 1990 and 1991, above- ground biomass was separated into live and dead material. In 1993, above ground biomass samples were sorted to live and dead material.
