Lianas are a type of climbing vine found throughout tropical rainforests. They have thick, woody stems and come in various lengths (up to 3,000 ft) and varying shapes. They begin life on the forest floor but depend on trees for support as they climb upwards towards the sunlight they need for survival.

What is liana in rainforest?

liana, also spelled liane, any long-stemmed, woody vine that is rooted in the soil and climbs or twines around other plants. They are a conspicuous component of tropical forest ecosystems and represent one of the most important structural differences between tropical and temperate forests.

Why do lianas live in the rainforest?

Lianas are climbing woody vines that drape rainforest trees. They have adapted to life in the rainforest by having their roots in the ground and climbing high into the tree canopy to reach available sunlight. Many lianas start life in the rainforest canopy and send roots down to the ground.
