## About

Planet Ark has organised National Tree Day since 1996, and it is now Australia's largest community planting event, held on the last Sunday in July with a Schools Tree Day the Friday before. You can search for a site near you, register your own site, or plant at home and record it. Councils, schools and businesses host most sites, and Planet Ark supplies the guides and signage.

If you run this organization, you can tell us what software you need at https://treerm.org/survey and send us an events feed at https://treerm.org/org/planet-ark/feed.
