Green Ash and Southwest Woods are Falling Down

All through the WSW section of the Woods, there are a large number of old trees coming down.  Long-dead bur oaks, big green ash and sugarberries. Windstorms have brought down an unusual number. I remember entering the southwest gate, and hearing the crash of a big tree falling a hundred yards north. Late this summer we also had many large canopy dominants snapped in half by strong winds. These seem to mostly have been big green ash and some big pecan. Their broken crowns filled with dead leaves, stand out in the bare forest of late November. Some will provide an extra bit of shelter on a cold winter night. I am curious how many of these will sprout new adventitious branches and new leaves. Trees that have been crushed by the falling larger trees and have lost their crowns have sprouted new leaves late this summer and these are now a fresh green while all the surrounding deciduous leaves are withering and falling.
Little bit smaller scale, the Oncideres twig girdlers have brought down an unusually large crop of branch tips this fall. I am curious what might emerge if I collected 40-50. Short science project. They seem to be mostly on pecan and elm, with a few of other species.

After an unusually wet, mild late summer, the past 50 days we've had no rain. The leaves in the Woods are crackling dry underfoot. The two ponds are still surprisingly well filled. By the East Pond, and by the second largest cottonwood south of there in the Big Tree Grove there are two unusual Euonymus bungeanus (?) wintergreen shrubs with leaves still green as the Woods becomes bare.
I took a saw to a couple equally large Lonicera maackii Amur honeysuckle shrubs growing in the dense brush along the West Dune Trail.

I have encountered two dogs running free in the Woods this autumn, the same two dogs on two different occasions. Both times in the east and southeast Woods. I have chased them off but I need to watch and see if they are coming back to the Woods. One is like the Budweiser dog, a bull terrier and its following companion is a lighter brown longer-legged dog.
