Field Trips - Monday, July 28 (2:00-4:00pm)

OPTION 1: NNI Management Projects in Sligo Creek Stream Valley Park
Trip leader: Carole Bergmann, MNCPPC Montgomery County Parks
Location: 9700 Sligo Creek Parkway, Silver Spring, MD 20901
Parking area is across from the golf course
Metro: From Forest Glen Road metro station take the 8 Bus east, get off at Sligo Creek Park Trail, walk south ¼ mile.
Description: Sligo Creek has a long history of successful NNI control, tour can be adapted based on group interest. We will leave the parking lot, be prepared to carpool. We will tour several sites in the Sligo Creek Stream Valley, looking at outcomes of different NNI control techniques, including:
  • Biocontrol: Mile-a-minute weevil & goat;
  • Mechanical: Volunteer pulling, deer exclosure & Selective herbicide.

OPTION 2: Restoration Projects at Heritage & Kingman Islands
Trip leader: Damien Ossi, DC Department of the Environment
Location: 600 Oklahoma Avenue NE, Washington, DC 20002
The entrance to the island is in the parking lot of RFK Stadium. If driving, enter the parking lot entrance to Lot 7 which is at 600 Oklahoma Ave. NE. Drive to the easternmost edge of Lot 7 and park near the black gate and wooden bridge to Kingman Island.
Metro: From Stadium Armory Metro station proceed north on 19th St. to Independence Ave. SE. Turn right on Independence Avenue and walk east for two blocks to the RFK parking lots. Continue straight on the bike path toward the Anacostia River. Walk east along the edge of the parking lot on your right and past the stadium on your left until you reach the Anacostia River Trail. Turn left onto the trail, walk under the bridge, and continue north along the river until you reach the Festival Entrance.
Description: We will tour two dredge material islands on the Anacostia River to view:
  • Restoration of a riparian forest using mechanical, chemical and biological methods (goats). Goats will most likely not be present.
  • Experimental plots established to measure the effectiveness of various methods chemical and mechanical control of phragmites in restored wetlands.
