Biological community establishment and succession depends upon environments that are characterized by regional physical and human processes. Ecological dynamics include trophic level interactions; food and nutrient availability; species assemblage, fitness and survival; and migration, colonization, and mortality rates. An example of community dependence upon physical processes is the distribution of habitat-forming species, such as bull kelp, which is determined by substrate, current, exposure, and light and water quality regimes. This species’ presence or absence impacts the ability of numerous invertebrate and fish species’ foraging, refuge, and survival. Sections three and four of this chapter will cover the biological processes of shore zone projects in more depth.
