Tree Alliance Competitors

Founded in 1972, the nonprofit Arbor Day Foundation is a million-member conservation and education organization with a mission of inspiring people to plant, nurture, and celebrate trees. More information about the Foundation's programs and impact are at www.arborday.org.

As the Los Angeles region faces severe impacts from climate change, TreePeople unites the power of trees, people and nature-based solutions to grow a more climate-ready city. The organization inspires, engages and supports Angelenos to take personal responsibility for the urban environment, facilitates collaboration among government agencies, and promotes leadership by grassroots volunteers, students and communities. Together, we are growing a greener, shadier, healthier and more water-secure Los Angeles for present and future generations. For more info, visit treepeople.org.

We are the environmental not-for-profit that thinks bigger than the environment. We started conserving and restoring Australia’s landscapes in 1982 and we haven’t stopped since. At Greening Australia, we work on major programs that bring life to landscapes and restore balance to the natural environment in significant areas across Australia. Our hundreds of projects demonstrate conservation on a massive scale, covering millions of hectares of land and protecting thousands of native species. From the warm waters of the Great Barrier Reef to the cool island ark of Tasmania, we’re thinking big to tackle the challenges facing Australia’s unique and diverse landscapes in ways that work for communities, economies and nature.
