Website from NEC where people leave messages as tree leaves. A visitor can only enter one message per day in order to enable as wide participation as possible. Up to 500 entries make one tree and after that a new tree appears. The numbers of entries, leaves determine an actual tree planting activate. For every 100 signatures on Ecotonaha NEC planted another tree addition to those planted during the Kangaroo Island project. Last year 2006 they had 107.054 messages and 1.070 trees were planted.
From website:
“ECOTONOHA IS A PROJECT – TO NURTURE A VIRTUAL TREE COLLABORATIVELY, AND AT THE SAME TIME CONTRIBUTE TO THE ACTUAL ENVIRONMENT TO COPE WITH GLOBAL WARMING. AS YOU MAKE ECOTONOHA’S LEAVES, THE VIRTUAL TREE WILL GROW, AND AS ECOTONOHA GROWS, REAL TREES WILL BE PLANTED BY NEC.”
This whole concept is well thought throw and the website very beautiful. It’s a good example of how a message board can be more and look better then a traditional message board. It is also an example of how the web can be used to encourage visitors to participate in something bigger then just the actual web site.
