Abstract

Carnation Creek is a long-term, basin-scale case study of the effects of forestry practices on a small coastal watershed. The broad objectives of this on-going project are to determine the mechanisms, rates, and levels of natural resource recovery in a harvested coastal drainage by describing long-term changes in biological and physical watershed processes as the second forest grows. Studies of hillslope, stream channel, floodplain, and riparian processes are integrated to model their functional linkages and determine the ultimate consequences for channel morphology, aquatic habitats, and fish populations. Empirical data covering a comprehensive suite of parameters including climate, streamflow, water temperatures, channel morphology, and fish populations were collected, analyzed, summarized in separate component reports, and archived in the project database. These data support the descriptions of the status of biological and physical attributes of the watershed 24 years after forest harvesting concluded. The data are used for the on-going development and refinement of basin-scale models for hydrology, landslide prediction, sediment and debris budgets, channel changes, and fish habitat capability. The information gained is relevant for validating current forest practices and supporting forest policy, regulatory, and guideline development to ensure the sustainable use of forest resources, and protect watershed processes and aquatic values. This report summarizes project progress for all study components the 2004-2005 project year.
