October 27, 2014 to November 1st, 2014, UMcares held UM biodiversity week. One of the main activities is tree mapping using open source data of pericopsis.org. The tree mapping session is conducted in three days: 27 and 30 October and November 1st, 2014. For the first and the second sessions, the trees were recorded into polygon "meeting". The tree mapping activities was started with a little speech by Benjamin Ong who explained the activity use pericopsis.org and followed by Jean Weber for the introduction of pericopsis.org. Later, the participants and the facilitators were separated into four groups for mapping the trees.

I am grateful to see the diverse range of background and age of the participants. As tree identification is a common knowledge which is border-less, a such variable range of participants is certainly interesting. The joyful and enthusiast of the participants and the facilitators made the sessions lively.

Mapping the trees using an open data source places UM as the leading university on the earth which voluntary share their trees to the world. The most interesting and the important facts of these activities is that the tree mappings have been conducted by volunteers.
