FOSC/Audubon Naturalist Society (ANS)
Biological Water Quality Monitoring/Data

The Audubon Naturalist Society has a well established, highly regarded macroinvertebrate monitoring program in the region. Friends of Sligo Creek began monitoring one site on Sligo Creek using the Audubon Naturalist Society’s water monitoring protocol in 2006. The site is located on Sligo Creek just south of where Sligo Creek Parkway meets University Boulevard in Wheaton (select the purple triangle on the map at right).

The primary goal of the monitoring is to have data for Sligo Creek represented in the Audubon Naturalist Society’s data set, which is periodically turned over to Montgomery County to help them assess the water quality of County streams. Other goals include public education, and to see for ourselves whether Sligo Creek’s water quality is getting better or worse over time. The Sligo Creek site has been named Audubon Naturalist Society Site 34.

The Water Quality Committee also conducts periodic cross section surveys of the stream channel at this site to see how it changes over time.

Keep an eye out for future monitoring events every season and join us! (You can join FOSC to get event updates and the newsletter delivered to your inbox.) NOTE: Due to the COVID pandemic, biological monitoring was suspended in Spring 2020.
