Mission Mapletree update

Here is a greeting from our tree. For those unfamiliar with the story, here is a small recap:

Right before Christmas we learned that the Metro Company were about to fell a tree on a coming construction site, in Krauseparken on Østerbro. With short notice we managed to halt the felling and gain a few days to move the tree. There were no private takers, so the City took mercy on us and offered a planting site in Fælledparken. The citizens managed to raise the funds in record time, and we had the tree picked up and moved to its new location. Initially we thought it was a mapletree but it turned out to be an American ash tree.

Immediately following the move, insane storms broke out. Several trees around the country fell over, and the same happened to our ash. Only not in the worst way, it was the soil that slid in the hole. The City's park managers attached support straps so the tree gets a chance to grow the all important fine roots that keep it fed and upright.

It grew up in shelter of other trees, but has been relocated on a windy corner, so we just have to wait and see if it manages to establish the roots, before the windy season kicks in. The tree bloomed by the book, but obviously the crown is not completely full, like before the move. We are hoping it will catch up next year.

On the bright side there is no heavy traffic on or near the roots and it is planted in fertile soil, in safe distance from salt. All we asked for, was that the tree was given a chance, and that is what it got.

Look at our sweet tree!

The tree grew behind this fence, and this is what it looks like today.

Hooray for giving the beautiful tree another chance.

Outcry from Enghavevej

Outcry from a citizen about the trees on Enghavevej. The entire row along the bike lane pictured, are to be felled any day now, for a "Safe School Passage". Does it get any safer than this? Madness!

What does it take to save the trees? There is still time!

A prep-team

At our meeting in spring, with the mayor of trees and his department chief, I suggested that the City implement a prep-team that would prepare, protect and clearly mark trees on building sites. This idea has received strong support from arborists.

Mere recommendations to protect the trees won't cut it. The current instructions are too vague, are not enforced and there are no sanctions for damages to trees. Worst of all, serious damages to the trees can be hidden for decades, before a large tree will suddenly fall, as was the case in the tragic, lethal accident by Fælledparken. With what turned out to be a roadwork-damaged tree.

The City must realize that status quo won't work. They must be willing to acknowledge the problem and look for alternative solutions. Below a picture from the University of Copenhagen on Øster Farimagsgade, where they are currently remaking the entrance.

The old giants are "protected" with flimsy, easily moved fences and plastic string. While digging and pouring a foundation directly in the drip-zone. Maybe they know no better. But the City does, and there is no excuse for turning a blind eye any longer.

Below: Instructions from The Danish Railroad, about working near trees. And two slides from Oliver Bühler of the University of Copenhagen, from the Urban Tree Seminar "Protection of trees in the building process".

From folder to entrepreneurs and builder, (in Danish) "Folder til entreprenører".

Text reads: With big trees (over four meters) digging is not allowed within the drip-zone (directly below the crown) or closer than half the tree-height from the trunk.
