Lianas are a long, woody vine that grows up from the forest floor and climbs up trees to get to the canopy. The relationship lianas have with trees is complex. Sometimes they link trees together, protecting them from high winds but If the wind is too great, however, many trees that are connected by lianas will get knocked down. There are also “strangler” liana that will slowly kill trees by growing over it and restrict its growth. They also serve as a bridge up in the canopy for animals, some of whom burrow in the trees or eat their leaves.
