WATER BUGS ARE ALIVE AND WELL! RESULTS ARE IN FROM 2007 MONITORING
In October, 2007, under a grant from the Sierra Nevada Alliance, specially trained volunteer monitors collected nearly 2,000 benthic macroinvertebrates (BMI) from four sites in the watershed. Our river is alive and well, according to the results received last summer following months of tedious laboratory analysis of those samples.
Different organisms tolerate different temperatures, oxygen levels, and other conditions, so the species identified in a section of river or stream can provide an assessment of water quality. The presence of three groups of BMI in particular, stoneflies, mayflies, and caddisflies, tell us that the Upper Merced River water is healthy!
Results from the 2008 monitoring of the same sites confirmed another year of the same good news and establish a solid baseline of data.

INVASIVE PLANT REMOVAL
For a Summer 2007 update on invasive plant eradication in the watershed, please click on River Reach Newsletter at left and see pages 6 and 7 of Volume 4.
Yellow starthistle and Italian thistle threaten the Upper Merced River Watershed as well as much of California. After four seasons of hand-pulling, mowing and Waipuna hot foam application, the Bureau of Land Management, US Forest Service, concerned individuals and groups have made progress in the removal of both of these non-native invasive species.
Volunteers play an important role in preserving our native plants. More volunteers are needed! Click on How Can I Help? at left.
