Using it for environmental education
Slide 3
Problem Invasive species are taking over other native plants
around the peninsula at Harford Glen.
Slide 4
How has the stewardship of Harford Glen impacted its
environment?
Slide 5
Research Question To what extent are the non-native invasive
plant species establishing themselves on the peninsula at Harford
Glen?
Slide 6
Invasive plants are plants that take over and harm an area or
environment by spreading rapidly and destroying other sources of
biodiversity. Some invasive species (plants) are Japanese Hop,
Devils Tear Thumb, Purple Loosestrife and Japanese Stilt
Grass.
Slide 7
Grows up to 10 feet and has prickles Female and male leaves are
born on separate plants Needs plentiful sunlight and moisture; it
usually grow s near bodies of water Japanese Hop is originally from
China, Japan, Korea, Taiwan, Vietnam and Russia Used as an
ornamental vine and medicine Came to America in the 1800
Slide 8
PlayersBeliefs Mr. Ramone Mowing would work better with
herbicides, but Harford Glen doesnt prefer or want to use them. Mr.
Burley Japanese Hop is interfering with projects like the checker
spot butterfly enclosures /exclosures near the peninsula that keeps
the deer from eating the white turtlehead, the butterflys favorite
plant .
Slide 9
PlayersBeliefs Mr. Ron Invasive species are a big problem to
the environment . Mr. Cromwell I dont like them. The invasive
plants cause a lot of problems to the local plants and they change
the landscape, and its just not normal.

Research Area
Slide 14
The only place there was Japanese Hop was the peninsula. Most
of the Harford Glen peninsula is covered with Japanese Hop because
its a flood plane. The Japanese Hop outgrows all the other plants
in the area. The Japanese Hop is thriving direct or partial
sunlight and moisture. Some of the Japanese Hop vines have wrapped
around the trees along the peninsula.
Slide 15
If the Japanese Hop doesn't have sunlight it would die.
Japanese Hop will take over the other areas of Harford Glen,
including the other invasives. Japanese Hop in the peninsula seeds
spread downstream, possibly from someone's garden.
Send an editorial to the newspaper persuading not to sell or
buy Japanese Hop Weed the Japanese Hop Contact local farms and 4H
about use of goats to clear Japanese Hop
