Lianas are an important but understudied growth form common to most tropical forests. Recent studies have documented the contribution of lianas both positive and negative to many aspects of forest ecology. Lianas contribute substantially to animals and are widely used by local people mostly for medicine but also for food house construction and artisan work. Lianas also play a substantial role in forest regeneration and such whole-forest processes as transpiration and carbon sequestration. Lianas however also compete intensely with trees and thus many forest managers favour a \"blanket liana cutting\" management plan if they address lianas at all. Here we review the role of lianas in tropical forests particularly those in West Africa and we recommend a more reasonable plan for the management of lianas in natural undisturbed forests.
