Which of the following does not characterise selva?

Selvas are the dense tropical evergreen rainforests of the Amazon Basin [c1, c2]. They are characterized by a multi-layered structure with a thick canopy of foliage and numerous climbing plants like lianas and rattan that hang from the trees [c1, c3]. Commercial utilization of these forests is notoriously difficult due to the extreme density of the vegetation, the lack of pure stands (high species diversity), and the heavy, hard nature of the timber which makes extraction and processing challenging [c3, c5]. While the Amazon faces significant deforestation threats today [t3, t9], it is not the biome that has suffered the 'greatest' destruction at the hands of man. That distinction typically belongs to temperate forests or tropical deciduous (monsoon) forests, which are easier to clear and have been settled by humans for much longer periods [t2, t10].
