Oak Wilt

Grows in the water-conducting vessels of host trees and as it does, it causes the vessels to produce gummy plugs that prevent water transport, eventually causing tree death.

Emerald Ash Borer

Description:they are metallic green beetle with wings and body tapered towards the rear.Damage:Larval feeding under the bark girdles and kills ash trees. Since its discovery in the United States in 2002 emerald ash borer has killed millions of ash trees.

Asian Longhorned Beetle

descriptions:Glossy black (think patent leather), very smooth beetle with white spots on the wings. Antennae are at least the length of the body and banded with black and white.Damage:Tunneling by larvae girdles tree stems and branches. This leads to dieback of the tree crown and eventual death of the tree.

Hemlock Wolly Adelgid

Description:A small aphid-like insect covered with white, waxy wool-like material. This wool-like covering makes the insect resemble miniature cotton balls. It is most visible from late-October through July. Wool masses are located on the undersides of the twigs at the bases of the needles (not on the needle, but on the twig).Damage:Feeding by the adelgid leads to needle loss, crown thinning and dieback and eventual mortality of trees.

How are these impacting the ecosystem

The Oak Wilt damages the feeding by the adelgid leads to needle loss, crown thinning and dieback and eventual mortality of trees.

The Hemlock Wolly Adelgid damages Feeding by the adelgid leads to needle loss, crown thinning and dieback and eventual mortality of trees.

What methods of preservation are working

watershed protections air puricfication recreation-example they are buying there

fire wood from camp sides .climate regulation

What methods of preservation are not working

the import of invasive plants poor timber management air pollution pests and diseases
