Greenstand's Treetracker app allows for tree planting initiatives and their donors to verify that their purchased or donated trees have been planted. Individual trees can be tracked to ensure that they grow past the vulnerable sapling stage and continue to provide valuable ecological services to their local environment. The app allows for tree farmers to take periodic geotagged photos of their tree(s). These images are verified by Greenstand and the tree farmer is paid for their efforts. In other words, growers receive supplementary income to support themselves and their families while mitigating the effects of climate change.
