The principle threats to Tennent’s leaf-nosed lizard are habitat fragmentation and loss, rainwater acidification, pesticides and the effects of climate change (5). Much of Sri Lanka’s original tropical moist montane forest has been cleared during the last two centuries for cinchona, coffee, tea, rubber and cardamom plantations, for grazing livestock, by logging companies, illegal logging and removal of timber by peripheral villagers (5) (8). The montane forests of the Knuckles Mountains where this species is found have been particularly affected by cardamom cultivation, which requires that much of the forest understorey is cleared and, although the canopy is retained for shade, continuing weeding of the area to remove competing vegetation prevents natural regeneration of the forest. Some areas are also still cultivated for vegetables using traditional slash and burn techniques and, on occasion, this can lead to out-of-control forest fires (6). With a rapidly growing population and increasing demand for agricultural land, the destruction of montane forests continues at an alarming rate. Further more, there is intensive use of pesticides on vegetable cultivations and tea plantations in Sri Lanka, which could be having a serious polluting affect. Although the impact these chemicals are having on non-target species is not yet known, studies elsewhere indicate that they could potentially be devastating, with possibilities for bioaccumulation. There is also evidence in the tropical moist montane forests of the Knuckles Mountains of large-scale forest die-back, thought to be the result of acid rain, and these forests are considered particularly at risk from climate change, especially global warming (5).
