Abstract

Rates of recolonization in natural open patches in a Massachusetts salt marsh were monitored for 3yr. Vegetative expansion of Spartina alterniflora at c12cm yr-1, accounted for most of the recolonization of open patches, although some colonization of annual Salicornia spp. occurred from seeds. Salinity and sulfide and ammonium concentrations were measured in pore water samples from depths of 2-7cm and 10-15cm of soil. Comparison of the concentrations from disturbed and undisturbed plots in the marsh did not show significant differences, indicating that none of the edaphic conditions measured would be more inhibitory to plant growth in disturbed plots. Rate at which small open patches become recolonized is thus primarily controlled by proximity of Spartina alterniflora and its capacity for vegetative expansion. -from Author
