| Summary: | 2.43 km away increased marsh use by some colonial waterbirds. abundance was greater in created than natural salt marshes. and gulls and tems was positively related to plant density in and marsh size. Bay habitat was positively related to number Birds were censused in seven natural and seven created salt density of plants in marshes. Since created marshes differed differed significantly, however not consistently. Bird differed. directly correlated to higher species diversity within the directly related to species diversity. This study indicates in Galveston. Six common marsh species were analyzed in some of these characteristics, bird utilization also marsh origin, size, and age. Birds were grouped by foraging marsh. Number of habitats within each sample site was marshes in lower Galveston Bay from October 1990 through marshes more than created marshes. Year round residents were marshes. Marsh size and presence of all habitat types were marshes. Natural marshes supported more rails and shorebirds method, prey items, habitat use, and season they are present more abundant in created marshes. Abundance of miscellaneous of summer, winter, and year round residents. Bird abundance or old created marshes. Gulls and tems occurred more in related to fall plant height. Gulls and tems were positively related to spring height. Abundance of year round species separately. Bird use was tested for relationships with September 1991 to evaluate differences in bird use due to Species diversity was greater in natural than created species, shorebirds, sparrows and all residence categories than created marshes. Sparrows were more abundant in natural than young created marshes. Winter residents used natural that bird use is influenced by marsh size, habitat types the inner marsh during spring. Location of active colonies < to active colonies. Bird use of created and natural marshes vegetation characteristics, habitat components, and distance was directly related to plant height. Year round species was positively related to amount of vegetated marsh habitat were positively related and waterfowl numbers negatively within marshes, distance to bird colonies, and height and young created marshes than either older created or natural Young created salt marshes supported more birds than natural |
