Soil from the Model Marsh excavation was hauled
approximately ¾ mile to an inland stockpile
site located in Goat Canyon adjacent to an abandoned
gravel quarry on the west slope of Spooner’s
Mesa.
In Fall 2000, the quarry slopes were reconstructed,
stabilized and planted with maritime succulent
scrub, a coastal habitat found in only a few
areas of San Diego County. Steep slopes were
reinforced with geotextiles and jute netting.
Maritime succulent scrub seeds were collected
from target plant species in the immediate project
vicinity and were broadcast over the reconstructed
slopes prior to the onset of winter rains.
An irrigation system was installed in Spring
2001 to assist in the establishment and persistence
of seed that germinated during the winter. A
monitoring and maintenance program will extend
over a period of at least five years to assure
that the reconstructed slopes are stable and
that the habitat is successful.
