Trends in Aquatic Habitat

A trend analysis is currently being completed determine if trends in habitat can be detected in coastal watersheds.  We developed a linear mixed model to assess trend with the following goals:

  1. Describe the trend in habitat conditions

  2. Determine the relative contribution of the variance components influencing trend detection capabilities

  3. Estimate the power to detect trends under multiple scenarios

  4. Discuss the implications of this trend assessment on future habitat monitoring
