Laguna Ecology & Biodiversity

The Laguna de Santa Rosa watershed is host to a wide variety of plant communities. The watershed’s diverse geology and wide climate range have together contributed toward the creation of an environment that supports many different types of plants, and an abundance of wildlife. Many of these unique species have been in decline and are now under the protection of the Endangered Species Act as their habitats have been threatened by habitat loss and fragmentation, pollution, and the introduction of non-native invasive species. Understanding the interplay between functional ecosystems and anthropogenic influences requires an investigation of the patterns of physical and biological forces at work in the watershed.

A detailed look at historic conditions and dynamics of the Laguna ecosystem and evaluating current conditions to establish a baseline for comparison of future conditions is essential to assessing the effects of human impacts in the context of yet unknown natural ecosystem variations. We are developing a program to establish a Laguna Biodiversity Baseline, and are collaborating with agency researchers and university graduate students to investigate specific ecosystem components and dynamics.

Laguna Trails Plan - Bird point count monitoring
With funding from Madrone Audubon Society and the Sonoma County Water Agency we continued a Laguna bird point count survey along the proposed Sonoma County Agricultural Preservation and Open Space District trail system this Spring. The survey was started in 2004 by PRBO Conservation Science to establish a baseline to assess potential impacts to Laguna bird populations from the trail. We were able to extend the survey for another season and hope to secure funding to continue for at least five more years. Several years of baseline data will ensure that this impact assessment is as scientifically sound as possible.
