Dune Stabilization Project
|We established the Dune Stabilization Project in 1988 in
conjunction with Sea Shore State Park to repair a blown out
dune near the eastern boundary of the park. This effort not
only provided a cheap, effective way of re-growing dunes, but
also gave us an on-going, environmentally-oriented scientific
study that students could engage in year after year. In addition,
it helped with the added benefit of keeping trees out of area
landfills. Last year, we invited several Cub Scout dens to help
put the trees in.
Transect with trees emplaced one month into study.

Abstract from Virginia Journal of Science,
Summer 1993, vol. 44, No.2
|"The recycling of Christmas trees is becoming more widely
used to assist in erosion control along the coast. From 1988
to 1993, five student groups participated in an on-going study
using recycled Christmas trees to repair a dune blowout at Sea
Shore State Park. Within three years, the dune was re-established.
After five years, 520 cubic yards of sand has accumulated along
the surveyed transect. There was negligible accumulation in
the slack behind the primary dune line."
Sand accumulation three years later. We had
to dig down to get to the sign
