TMA is actively restoring degraded lands; every year we plant about 8,000 seedlings of native understory and canopy species and also broadcast seeds. Important areas with ongoing or proposed restoration projects include Keauhou Ranch and Lupea (land owned by Kamehameha Schools), Pu‘u Wa‘awa‘a (DLNR), and sections of the Pu‘u Maka‘ala Natural Area Reserve (DLNR).
The vast majority of the seedlings are grown in our greenhouse from seeds collected in areas where we will later focus our reforestation efforts. Reforestation occurs in two phases: first canopy species are planted, once these are big enough to provide sufficient shade, understory species are planted.
Our planting techniques in wet forest sites have been perfected over the years; monitoring results show a survival rate of 85-95% depending on species. Efforts in our dry forest site at Lupea (North Kona) are just getting underway. We are experimenting with different planting and watering techniques and are carefully monitoring results.
Restoration efforts are often combined with environmental education & service learning activities.
