Abstract
Mikania micrantha, an aggressive invasive plant known for its rapid growth, is posing a serious threat to various forestry crops in Kerala. This weed, a perennial climber, affects both trees and subsistence crops either through cost escalation or through income reduction or both, in addition to other ecological damages. This paper attempts to examine the economic impact of Mikania, especially in terms of cost and income, on teak plantations in Kerala. The study, based on primary data, has observed that it has enhanced the cost of planting and has adversely affected the profitability of teak plantation in the study area.
