Project summary:

The Stow Conservation Commission has been actively monitoring and managing a patch of Japanese stiltgrass (Microstegium vimineum) an early detection species, located at Flagg Hill Conservation Land which was identified in 2014. The Conservation Commission had received reports of Japanese stiltgrass patches in other areas of Flagg Hill and at Stow Town Forest. There are concerns that Japanese stiltgrass may spread along a drainage course of Flagg Hill toward Heath Hen Meadow Brook.

In 2015, the Commission received $700 of funding to survey and remove Japanese Stiltgrass at Town Forest, Flagg Hill and Heath Hen Conservation Lands. The remaining funds from the 2015 stilt grass survey and removal project were used in 2016 to monitor the stiltgrass patches that were removed in 2015.

Control method: Manual, Mechanical

Disposal method: Bagging

Detailed project timeline:

2014: a patch of Japanese stiltgrass was detected in the Town Forest
2015: Funding for monitoring and conrol was received through CISMA

In August, staff members worked to manually pull and weed whack stiltgras before it went to seed. In the second year of management, the original 40'x40' patch at Flagg Hill took less than an hour of work, the patch in the Town Forest took about 30 mins, and the newly discovered 5'x5' patch at Flagg Hill took about 4 hours.
