Short Communication: The ecological and economic values of secondary forest on abandoned land in Samarinda, East Kalimantan Province, Indonesia

There is a large area of abandoned land that is not taken manage of after plantation activities in the tropic. These abandoned gardens which have been neglected for a long time have important ecological and economic values. This study aims to assess the existence of abandoned land in the tropic from...
