Our idea was not to recruit expensive human donation collectors, but an entirely new breed of 'activist', who would happily work the streets around the clock for free and who was a very natural and convincing advocate for OroVerde's message: Trees. We equipped a whole army of 600 trees in pedestrian areas, shopping streets and parks throughout Germany with cardboard signs, turning them into tireless donation collectors.

Hundreds of trees in Germany's pedestrian areas, shopping streets and parks. Equipped with cardboard signs like street beggars, the trees asked for donations on behalf of their suffering relatives in the rain forest.More than 600 'volunteering trees' were recruited all over Germany. Cash donations rose by 27.4%. And the tropical rainforest foundation OroVerde, formerly known only to insiders, enjoyed a wave of public interest.
