Lianas are woody climbers. They are often known as the 'highway' of the forest. The leaves of the liana are found near the top of the canopy to absorb as much sunlight as possible for photosynthesis. The liana then spreads along a few trees as it grows. This forms the 'highway' at the canopy of the forest, thus the animals like squirrels do not need to climb up and down the trees to get from one tree top to another. If one of the trees twined by the liana is to fall in the forest, it will bring down the other trees too. This allows the pioneer species to grow when there is a sudden gap in the canopy.
is this the plants used by Tarzan to swing from one tree to another too? :)
