Winter Is Our Quiet TimeThe Department of Fish and Game does not allow any restoration activities in creek channels during the winter because it is a sensitive time for many aquatic species. The habitat needs to remain undisturbed for them. However, it is possible to work in the butterfly habitat (see below). Since most trees are bare during the winter, it’s a good time to see birds and get a better idea of what the creeks themselves look like. Next Volunteer Opportunity The next volunteer day for the creek will be butterfly habitat maintenance in Civic Park East sometime in February. If you or your group would like to help, please Contact Us. Bioassessment Program Last spring we participated in the bioassessment surveys which support Contra Costa County's clean water permit. Working under the direction of a county staff person, we collected benthic macro invertebrates (aquatic insects) in the creek, measured the width of the channel and the amount of shade cover, and estimated the characteristics of the water flow. We spent the day walking in the water in chest waders and doing real science and it was a lot of fun. Last year, participation was limited to adults and you had to commit at least half a day, preferably a whole day, to the work. The permit requirements have changed this year, so the bioassessment program may change as well. If you are interested in participating or have questions, please Contact Us . Save the Date! The annual creek cleanup will be May 9, 2009. Creek Walk UpdateThe Creek Walk project in Civic Park East has been approved and we are now helping staff to apply for a grant. The project includes expanded riparian habitat, interpretative signage, realignment of the bike/pedestrian path, enhanced landscaping at both ends, and the addition of a pedestrian-only path closer to the creek bank. |
