Oak wilt killing my oak trees??
Oak wilt has been found in western MD. But we have not seen it in the eastern area of the state. See our link http://extension.umd.edu/hgic/invasives/oak-wilt
There are multiple factors that can contribute to decline of oak trees. When subject to drought, poor soils, poor drainage, etc. they can be susceptible to insect and disease problems. These issues put the trees under severe stress and can result in root loss. Also, in a forest or natural setting trees decline and there is regeneration all part of the ecology.
Also, here is an article on Why Oak Trees Are Declining http://extension.umd.edu/hgic/topics/why-oak-trees-are-declining
The photos are out of focus. It looks like there is wood decay fungi on the trunks and the trees have been declining for several years. Once the trees leaf out look for decline and symptoms on the foliage. You can send us photos.
Lastly, You may want to contact several certified arborists for an onsite diagnosis regarding the health of the trees http://www.treesaregood.org/
