Run tourist projects and ensure permanent human presence at site Primate Conservation

One before-and-after and review study in 1986-2010 in montane rainforest in Ranomafana National Park, Madagascar found that after implementing a lemur tourism project alongside other interventions, the population size of Milne-Edwards’ sifaka Propithecus edwardsi and greater bamboo lemur Prolemur simus declined severely while the golden bamboo lemur Hapalemur aureus had increased in population size. In 1996-2008 population size and group size of Milne-Edwards’ sifaka declined, with almost 50% decline in population size in 2005-2009 (data as graphs) and a 7% reduction in body size over 21 years (5.7kg in 1987; 5.3kg in 2008). High tourist numbers in one site resulted in changed activity patterns for Milne-Edwards’ sifaka, with less time spent foraging and grooming (data as graphs). Population size and group size of greater bamboo lemur also declined following the implementation of a tourism project while golden bamboo numbers increased (data not included). In 1993-2011 the number of tourists in Ranomafana increased from around 4000/year to almost 24000/year (data as graphs). Lemur behaviour and population counts were collected in several studies.
