Life is tough in a public space....
Not sure who or what went after this Accolade Elm sapling (#100 in our Adopt A Tree program) around July 10th but we're told by Parks, Forestry and Recreation that it most likely won't survive in the long run - although it may live for a few years. Unfortunately their warranty won't cover vandalism, so it won't be replaced.
The tree transports water up through a layer called the xylem and transports nutrients and the products of photosynthesis back down to the roots through the phloem layer, which is just below the thin outer layer of bark. If the phloem layer has been completely removed then this tree will have a slow death from lack of nutrients.
The tree guard seen in the photo protects the trees from weed-wacker damage -- any damage affects the tree's ability to transport water and nutrients -- but wasn't up to stopping the perpetrator here.
The tree will also likely suffer from sunburn now too -- yes, trees can get sunburned.
If you see damage being done to the trees, please use the "Key Park Contact Info" list to report it. Together we can help keep the park safe and healthy.
