Vines growing on tree trunks create visual interest and sometimes a temptation to swing. However, vines threaten trees by competing for light and adding weight to their canopy. Swinging is dangerous, as it may bring down dead branches, break other branches, and the vine itself.
Vine control involves the removal of a section of vine at the tree base, or at least cutting so the vine cannot reconnect and heal. Don’t tug the vine; that may pull off tree bark. Instead, cut and gently remove a section of vine at the base of a tree, careful not to cut the tree bark. Then, pull out the vine’s shallow roots to create a vine-free zone. This area is easily monitored for new vine growth. Let the remaining vine wither and loosen. A year or two later, attend to loose vine removal with caution.
Many vines growing on trees are invasive species. In particular, English ivy (pictured here), Oriental bittersweet, and Oriental honeysuckle threaten trees. Poison ivy, a native, can also grow thick vines on a trunk. Make sure you know how to recognize it.

Well, no.
Some reasons:
They bring excess nutrients and potential invasive seeds to an area that was restored to provide a natural riparian buffer.
They bring residual lawn chemicals (if used)
They do nothing to hold the soil - in fact quite the opposite - they choke vegetation that would otherwise be providing that critical function for a riparian buffer.
Better solutions might be to use a mulching mower, or ask a neighbor if they want the leaves for mulching or composting, or ask the local municipality what options they can suggest for these yard wastes.
Among the ecological purposes of mulching trees, stabilizing soil moisture and controlling weed germination and growth are key.
But one practice is counterproductive: Piling up mulch against a trunk softens the tissue, making it more vulnerable to disease. The practice stimulates girding roots, which can slow growth and may kill the affected tree in due course. Where mulch is too thick, the near-surface roots can no longer perform their gas exchange function. While many trees may appear to tolerate these stresses for a time, they may not thrive.
The tree pictured here has been freed of the four inches of mulch placed against it above its planting depth.
The International Society of Arboriculture and Penn State Extension provide more information about mulching.
Even small stone dams, built for fun, can trap floating debris and create larger backups that interrupt natural flow. The diverted flow can carve further into already unstable stream banks, causing more soil to end up in the creek.
Little dams can increase sediment deposition upstream of the dam. Not great for critters with gills.
Poor conservation-minded folks have to remove your dam, to help return to a more natural flow. We tire easily. Be kind, and give us a break!
