Fallen & corrected

Significant vines going up the tree

Mild vines accessible from the street

Lots of dead wood

This tree is going to fail out of the woods very soon and needs to be removed

It is surrounded by poison ivy growing from the ground

This tree is not doing well. It needs water and care.

Substantial vines and accessible from the street

Not a lot of canopy left, and there are substantial vines going up the tree

Breakdown the mulch ring and make it bigger

It has a very interesting corrected lean

Major vines, mostly native Grapevine coming in from higher in the canopy

Overtopped

It is close to being completely over topped by native grapevines

Substantial native grapevines are over topping the tree, and it has a broken hanging limb

There are a lot of need of grapevines and the tree has a crook

Really interesting structure how it leans up slope dramatically, and has in contorted canopy

Substantial poison ivy and you on this vine, growing up it with some porcelain berry as well

Large poison ivy vine with the vines coming out horizontally so I wasn’t going to get close to this one

One of the best elms in this whole forest and worth preserving

Moderate English Ivyvine coverage

Moderate vine infestation from English IV

I confirmed it is a white mulberry and it has an English IV vine growing up the middle, which is taking over a substantial part of the scaffold limbs. There is also a poison ivy vine on the street side.

The tree is mostly dead on the main stem and has a living side stem

Two codominant limbs originate about 1/3 of the way up the tree, and there are some small diameter, dead branches that are in the canopy

Poor center leader but the sides look good

Moderate vine infestation from English IVy and it’s pretty easy to cut with no poison ivy in the immediate vicinity

Only English Ivy growing up this one

There’s a substantial amount of English IV at the top of the tree, but the vines are easy to cut. There is a little bit of poison ivy at the base.

This is the worst vine infestation that you could reasonably manage without English ID. Do you wanna is fine is insane and then the English I be underneath is formidable, but I did not see any poison ivy.

Transplanted from Nebraska Hall due to dormitory construction.

Major infestation from euonymus Vine, and maybe some English Ivy underneath but no poison ivy

Overtopped with cavity

There is a lot of English Ivy growing up the tree, but no poison

Cavity in base

Severe vine infestation makes it extremely difficult to measure so it will need some pruning around the area before I get a more accurate reading, but there is no poison ivy

Needs mulch ring

Not the worst fine infestation but definitely something to manage. It’s grown up about half the scaffold limbs in the tree has a nice U-shaped around the powerline so it will not be hacked back.

Significant die back from spotted lantern fly

Mild vine infestation

I don’t see any poison ivy immediately around the tree, but the vines are really intense on this one and it’s worth saving

Severe vine infestation, but it appears treatable, and there is no poison ivy right around the tree

Major candidate for removal

Topped for utility pruning

Mild vine infestation, but there is poison ivy surrounding the tree

Poison ivy on the ground surrounding the tree and a small vine climbing up

This tree has a really hard lean and a bunch of sprouts coming off the side and interferes with the pathway it should be removed
