Assuming the recent rate of decline remains constant, the species is projected to decline by 35-40% over the next three generations. Since this species has a long generation length, with three generations stretching over 42 years, there is insufficient evidence to calculate the magnitude of reduction over the past three generations. The rate of decline is therefore placed in the band 35-40% over three generations. Thus, its actual rate of population decline is likely greater than the estimate decline based on forest loss alone, possibly exceeding 35% over three generations. Being largely restricted to primary forests and intolerant of habitat conversion, the species is additionally threatened by hunting. Trend justification: An analysis of deforestation between 20 estimated forest loss within the species's range at a rate equivalent to 35% over three generation lengths (42 years) (Tracewski et al. A pair will wall up the hole with mud and droppings, the male on the outside and. In Sabah, Crocker Range Park and Tawau Hills Park had population densities of 0.94 individuals/km 2 and 5.67 individuals/km 2 respectively (Lakim & Biun 2005). Rhinoceros hornbills nest in cavities or holes high up in old or dead trees. What is the purpose of this casque, and how well. Recognized as one of the region’s most iconic birds, it impresses observers with its attention-grabbing casque a stunning, hollow horn that extends from its upper bill. In Sarawak, Upper Baram and Batang Ai National Park had population densities of 0.27 individuals/km 2 (Chin & Jantan 2001) and 0.96 individuals/km 2 (Meredith 1995) respectively. The Rhinoceros Hornbill is an awe-inspiring bird species that inhabits the thick mountain rainforests of Southeast Asia. In Kuala Lompat (Krau Wildlife Reserve) the population density was 2 individuals/km 2 (Medway & Wells 1971). In Peninsular Malaysia, Sungai Tekam Forestry Concession (Pahang State) population density was found to be 1.6 groups/km 2 in primary forest and 2.3, 1.8, 1.2, 0.4 groups/km 2 in 0-6 month, 1-2 year, 3-4, 5-6-year-old logged forest respectively (Johns 1987). The species is widespread throughout its range, but occurs at low densities, even in suitable habitat (Poonswad et al. A rhinoceros (/ r a n s r s / from Ancient Greek (rhnkers) 'nose-horned' from (rhs) 'nose', and (kras) 'horn' pl.: rhinoceros or rhinoceroses), commonly abbreviated to rhino, is a member of any of the five extant species (or numerous extinct species) of odd-toed ungulates in the family Rhinocerotidae it can also refer to a. Population justification: The population size of this species has not been quantified. Rate of change over the past & future 10 years/3 generations (longer of the two periods) Rate of change over the future 10 years/3 generations (longer of the two periods)
