A few sediment samples from Trench 40 and Core 2, outside a fishpond at the Coco
Palms Site on Kaua’i, were examined for pollen and microcharcoal to provide information
concerning use of this area during the past. Since the sediments were collected outside the
fishpond, which had been dredged, they might represent earlier fishpond deposits from a time
when the fishpond was larger than it is today. Radiocarbon ages returned for several samples
indicate an age of 1440-1640 A.D. associated with sample 1 from Trench 40, and ages of 1300-1400 A.D. and 530-650 A.D. associated with Core 2. Pollen analysis was undertaken to search
for a clear, discrete change in plants represented. A change from a pollen record reflecting
native plants to one dominated by sedges and grasses should result from burning local
vegetation and in association with swidden agriculture. Two samples were selected from
Trench 40 and three from Core 2 to examine the pollen record. In addition, two surface
samples were provided for comparison, but not included in the budget. Therefore, these
surface samples were examined in a very cursory manner, since there was no money allocated
for their analysis.
