The Kilimanjaro Consortium for Development and Environment (KCDE) runs a tree nursery that is led by Dr. Aidan. The purpose of the nursery is to grow trees that will be used to continue the re-greening efforts on the slopes of Mount Kilimanjaro. The tree nursery is preparing for the planting season, which is when the trees grown in the nursery will be planted on the mountain. This is a crucial step in the re-greening process and will help to restore and protect the tree cover on the mountain.
