Tree and shrub establishment and survival on sandy dredged material.
MetadataShow full item record
Eight tree and shrub species were transplanted on sandy dredged material from the intracoastal waterway on Bolivar Peninsula, Texas. Winter plantings of trees and shrubs established and grew better than summer plantings. Elevations of plantings were critical for Tamarix gallica (salt cedar), Pinus clausa (sand pine), and Croton punctatus (gulf croton). Tamarix gallica cuttings and Pinus clausa seedlings survived better in moist than dry substrate. Croton punctatus survival and growth was poor in wet substrate, but good in dry. Quercus virginiana (live oak), Rhus copallina (dwarf sumac), and Myrica cerifera (southern wax myrtle) appeared to have the widest tolerance for substrate moisture conditions. These species or similar adapted species may allow habitat development for wildlife species on dredged material.
