Arlington Fairfax Chapter

of the

Izaak Walton League of America

Invasive plants found on the property

Multiflora Rose - Rosa multiflora
Forms dense thickets that exclude native plants. Multiflora Rose can be found around the pond and alongside the stream that feeds the pond.
Yellow Rocket - Barbarea vulgaris
Has become started to establish itself over the past two or three years
Chinese Lespedeza - Lespedeza cuneata
Chinese Lespedeza is present throughout the campground and in the powerline right of way.
Japanese Honeysuckle - Loniera japonica.
Japanese Honeysuckle can be found throughout the property but it is particularly thick around the pond where it can get plenty of sun.
Japanese Stilt Grass - Microstegium vimineum
Japanese Stilt Grass is present throughout the property.
Garlic Mustard - Alliaria petiolata
Garlic mustard seems to be growing in a band roughly parallel to Route 66. Garlic mustard has only recently appeared on the Chapter property. I first observed it in 2010 along the banks of Cub Run although it likely existed at least a year before then.
Autumn Olive
Scattered through out the property. Large concentration of established bushes by the Walnut Grove.
Also known as wine rasberry. Currently it seems to be wildly dispersed. Likely orignating in some bird droppings, it would be best to control it before it gets out of hand.

How has this situation come to pass?

Many native plants would out-compete these invasive species were it not for large population of deer in the area. Deer favor native species browse pressure of deer
