Harford Glen was purchased by
Harford County Public Schools in
1948 with the conditions of:
 Keeping it in a natural environment
 Using it for environmental
education
Problem
Invasive
species are
taking over
other native
plants
around the
peninsula at
Harford
Glen.
How has the stewardship
of Harford Glen
impacted its
environment?
Research Question
To what extent are the non-native invasive plant species
establishing themselves on the peninsula at Harford Glen?


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, Devil’s Tear Thumb,

Beliefs
Mr. Ramone
“ Mowing would work better with
herbicides, but Harford Glen doesn’t
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 butterfly’s ‘favorite plant’ ”.
Players
Mr. Ron
Mr. Cromwell
Beliefs
“ Invasive species are a big
problem to the environment ”.
“ I don’t like them. The invasive
plants cause a lot of problems to
the local plants and they change
the landscape, and it’s just not
normal.”
We tracked the area where Japanese
hop was growing with a GPS.

The only place there was Japanese Hop was the peninsula.
Most of the Harford Glen peninsula is covered with
Japanese Hop because it’s 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.



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.
