and Similajau National Park. MiriSibuti National Park is known for its coral reefs and Gunung Gading National Park for its Rafflesia flowers. Bako National Park, the oldest national park in Sarawak, is known for its 275 proboscis monkeys, and Padawan Pitcher Garden for its various carnivorous pitcher plants. In 1854, Alfred Russel Wallace visited Sarawak. A year later, he formulated the "Sarawak Law" which foreshadowed the formulation of his (and Darwin's) theory of evolution by natural selection three years later. The Sarawak state government has enacted several laws to protect its forests and endangered wildlife species. Some of the protected species are the orangutan, green sea turtle, flying lemur, and piping hornbill. Under the Wild Life Protection Ordinance 1998, Sarawak natives are given permissions to hunt for a restricted range of wild animals in the jungles but should not possess more than of meat. The Sarawak Forest Department was established in 1919 to conserve forest resources in the state. Following international criticism of the logging industry in Sarawak, the state government decided to downsize the Sarawak Forest Department and created the Sarawak Forestry Corporation in 1995. The Sarawak Biodiversity Centre was set up in 1997 for the conservation, protection, and sustainable development of biodiversity in the state. Conservation issues Sarawak's rain forests are primarily threatened by the logging industry and palm oil plantations. The issue of human rights of the Penan and deforestation in Sarawak became an international environmental issue when Swiss activist Bruno Manser visited Sarawak regularly between 1984 and 2000. Deforestation has affected the life of indigenous tribes, especially the Penan, whose livelihood is heavily dependent on forest produce. This led to several blockades by indigenous tribes during the 1980s and 1990s against logging companies encroaching on their lands. Indeed, illegal logging in particular has decimated the forest regions indigenous populations depend on for their livelihoods, depleting fish, wildlife, but also traditional medicinal herbs and construction staples like Palm. There have also been cases where Native Customary Rights (NCR) lands have been given to timber and plantation companies without the permission of the locals. The indigenous people have resorted to legal means to reinstate their NCR. In 2001 the High Court of Sarawak fully reinstated the NCR land claimed by the Rumah Nor people, but this was overturned partially in 2005. However, this case has served as a precedent, leading to more NCR being upheld by the high
