Text Appearing Before Image:
Once brackish species have invaded an intertidal area, it is likely that they will persist. With continually augmented streamflows, as would occur with upstream wastewater discharges, species with salt- tolerant, vegetatively reproducing adults might never die out. At San Diego River marsh, the cattail population that invaded in 1980 enjoyed a second expansion in 1983, when rainfall and streamflow continued late into spring. With drier conditions in 1984 and 1985, the population declined (Zedler and Beare 1986). 3.6 ESTUARINE CHANNELS AND TIDAL CREEKS The channel habitats are important for a wide variety of organisms including macroalgae, phytoplankton, invertebrates, fishes, and birds (Figure 3.18). The California least tern and other fish-eating species feed in the deeper-water habitats, while shorebirds probe the sediments of the intertidal zone at low tide.

Figure 3.18. The channel and tidal creek habitats support an abundance of species including the marbled godwit, which probes the mud for food, the topsmelt, which attaches its eggs to macroalgae, the diamond turbot, which feeds on the benthic organisms, and gaper clams (Tresus nuttallii), ghost shrimp, and commensal arrow gobies, which live within the sediments.
