The Great Urban Tree Map Showdown

Berlin’s map is for pros, New York City’s is for the masses.

 

I have noticed the online tree maps from the Berlin and New York City parks departments are very different and decided to compare them. Both cities have mapped their street trees – allegedly all of them – and made interactive maps and data publicly available but they have interesting differences.

Living buildings

Just a few quick words about a fascinating little corner of the arboriculture world known as tree shaping or arborisculpture, the training of living trees into sculptures, furniture, buildings and other structures. (The far more common espalier is a tree or shrub trained to grow flat against a frame or wall, often for increasing fruit production.)

The field’s greatest visionary was Arthur Wiechula (German, 1867 – 1941) who envisioned growing entire buildings and researched the physiology of the necessary grafting.

Smaller works such as chairs and individual sculpted trees are documented since at least the 19th century, with Germany perhaps the chief center of activity, followed by the UK and US. Germany has most of the world’s living buildings – a couple of churches and a four story pavilion. India, however, has largest, oldest and most functional living structures. In the state of Meghalaya are footbridges, formed of living roots of Ficus trees, that reportedly are centuries old and able to support 50 people.
