The Open Elm Project is the result of a collaboration between Island-based Red Robot Studios and Isle of Man Department of Environment, Food and Agriculture.

The aim of the project is to harness the power of the public to help create a detailed profile of the Island's elm tree population, and to help identify and report trees which may be infected with Dutch Elm Disease.

We have developed this website which enables you to submit the location, health and a photograph of an elm you've spotted, and have built an iPhone and Android mobile apps which makes it easy to record trees while you are out and about.

All data collected by the project is completely public making it the Island's first project to provide public access to the data without restriction, and also the first in using enabling the members of the public to easily collect and contribute valuable information.

We'd love to hear any suggestions on how you think we could improve the site, so feel free to drop us an email at hello@openelm.org.im.

Open Data and Open Source

The Open Elm Project is a completely transparent project: all data is fully available and so is the source code for the website and mobile app.


Thanks to: Andrew Sidebottom, Jimmy Lee and Doug Chalk from Isle of Man Department of Environment, Food and Agriculture for their support and enthusiasm, and also to John Shimmin MHK for being open to the idea when it was first presented.

Thanks to all the Django, CouchDB, jQuery, jQuery Mobile, Celery, PhoneGap, CouchDBKit and nginx contributors for giving us the tools to put this project together on a fully open source stack.

What is Dutch Elm Disease?

Dutch Elm Disease can be transmitted from tree to tree by the elm bark beetle, root grafts and infected pruning tools. An infected elm tree usually exhibits symptoms soon after infection.

Because of the speed with which the disease attacks, detecting symptoms as early as possible is essential for treatment. The main symptoms to look out for are:

  • Wilting of leaves and young shoots
  • Premature yellowing or discolouration of leaves
  • Retention of dead leaves
  • Rapid development of symptoms
