The picture shows extremely healthy and abundant plants at Seneca Creek State Park.

The grasses at Rocky Point and Gunpowder State Park Hammerman Areas continue to thrive and are producing seed pods throughout each consecutive year’s planting area. The fact that these classroom grown grasses continue to expand each year is very promising, and we will continue to search out new sites for restoration.

These sites will be monitored as well as other sites from previous years throughout the summer. If the grasses continue to do well, we will continue to expand the planting areas in the future. We appreciate all of your hard work this season growing your bay grasses, and hope to see you next year.
