In late 2008, part of Big River Haul Road started to erode into the Big River estuary. This problem was due to lack of vegetation to hold the soil together . The landslide soil mixed with the estuary water and contaminated the estuary by increasing the amount of soil in the water. This was greatly disruptive to the underwater ecosystem. Therefore, Mendocino Fish and Game Department decided to tackle the issue. Along with students from Ukiah and Fort Bragg, our Sonar class planted 3-5 year old Dougls Fir Trees along Big River Haul Road. With support and help from the community members and students, Fish and Game managed to plant over 200 trees.
Sonar has been working on counting salmon population up at Little North Fork of Big River for the last two months and has had success in finding yoy(Young Of the Year) and redds(salmon nests) along the paths of the beautiful redwood forests. During the hatching and reproduction periods, Sonar students have been collecting sample data to examine and compare differences in a majority of species, sizes, and populations.
As the year progresses and new upcoming environmental issues arise, Mendocino High School’s Sonar class continues to contribute their experience and knowledge to the community. Its two enthusiatic teachers Robert Jamgochian and Doug Nunn are the driving forces behind the wonderful work that this class has accomplished.
