Abstract

Only Acacia mangium and A. auriculiformis are planted. A. auriculiformis was introduced in the early 1980s in the Luzon area for fuelwood. A. mangium has been planted in Mindanao for electricity poles and watershed rehabilitation. In Mindanao there are also many tree farms and cooperatives the only place in the Philippines with this. An NGO project has planted 750 ha. of A. mangium with a few hundred farmers with another 300-400 ha planted by individual farmers. In 1989/90 ADB funded contract afforestation of 13 000 ha of A. mangium. In Luzon there are 10 000 ha of A. auriculiformis spread over three regions while in Mindanao there are about 2 000 ha contracted but it is not certain that the area has really been planted. An ADB-funded project on community-based reforestation of 170 000 ha with 120 000 in uplands and 20 000 in mangroves. Of this 80 is for plantation and 20 for agroforestry. Species are a mixture of nurse and climax species such as narra acacia mahogany including about 37 000 ha of acacias which are usually planted for fuelwood and as nurse species. They are planted in mountatin areas for rapid protection. Some acacias are planted in Metro Manila as roadside trees and also in some colleges. Most species have little or no growth and yield data.
