A liana is any of various long-stemmed, woody vines that are rooted in the soil at ground level and use trees, as well as other means of vertical support, to climb up to the canopy in order to get access to well-lit areas of the forest. Lianas are especially characteristic of tropical moist deciduous forests and rainforests. These climbers often form bridges between the forest canopy, connect the entire forest and provide arboreal animals with paths across the forest. These bridges also protect weaker trees from strong winds. They also compete with forest trees for sunlight and soil resources (water and nutrients). There are also temperate lianas, however, for example the members of the genera Clematis or Vitis (wild grape). Well-known lianas include Monkey Ladder (Bauhinia sp.), Water Vine (Cissus hypoglauca or members of the genus Doliocarpus), but not Pothos (Epipremnum aureum), which is classified as an epiphyte or herbaceous vine.
