Pad Tad Ke Botanical Garden is relatively new, a work in progress that has assembled plants from all over Laos and other parts of Southeast Asia. The garden project is a privately funded non-profit supported by corporate sponsors. A visit to the garden costs around $20, which is a bit pricey for these parts. Any surplus revenue beyond operating expenses is invested in training programs for Laotian and ethnic minority farmers. Experts visit villages to help farmers understand sustainable agriculture, among other things, teaching farmers who practice slash and burn agriculture how to burn without doing lasting damage to the forest, and how to cut down trees in ways that are sustainable.
