The production of palm oil requires intensive deforestation and this has led to a gradual loss of flora and fauna in the areas where land is cleared for the cultivation of palm oil.[14] Tropical rainforests in countries including Malaysia and Indonesia have been the most ideal countries to have large palm oil plantations as they provide the most suitable climate with ample rainfall and sunshine throughout the year.[15] Between the years 1990 and 2005, the total land in Malaysia used for palm oil cultivation increased by 2.4 million ha and reached 4.2 million ha.[16] During that period, over 1.1 million ha of tropical rainforest was lost. The diverse biodiversity that each rainforest possesses has been diminishing at a rapid rate as fauna is often very fragile and easily affected by deforestation.[17] Animal wildlife has been most affected in areas where significant amounts of land, for commercial palm oil purposes, have been cleared to allow the trees to be planted.[18] Animals have been forced to relocate and have increasingly come into contact with humans as they have started to roam around the surrounding villages in search for food.[19] Some animals have not been able to adapt and relocate elsewhere, leading to their populations decreasing significantly and this has disrupted the symbiotic relationships that the flora and fauna have with their habitat. Deforestation negatively affects biodiversity when forests are converted into plantations and leaves relatively low species richness in primary forests compared to undisturbed forests.[16] One species of particular concern is the critically endangered Bornean orangutan. A notable study in 2018 showed that from 1999 to 2015, over 100,000 orangutans were lost due to unsustainable natural resource exploitation (including the palm oil industry). This number was obtained by tracking the number of nests over this 16 year study period. Results show that nests declined from 22.5 nests per kilometer at the start of the study, to 10.1 nests per kilometer by the end of the study.[20] On the other hand E. guineensis cultivation also helps to push species invasions further, e.g. Anoplolepis gracilipes in southeast Asia.[21] Biodiversity suffers in almost all taxa – Room 1975 and Fayle et al 2010 find so for ants, Danielsen and Heegaard 1995 for bats and primates, Liow et al 2001 for bees, Chung et al 2000 for beetles, Peh et al 2006 for birds, Davis and Philips 2005 for dung beetles, Hassall et al 2006 for isopods, Glor et al 2001 for lizards, Chang et al 1997 for mosquitoes, Chey 2006 for moths, and Bernard et al 2009 for small mammals.[22][23] Almost all taxa also suffer loss of abundance but there are exceptions, species which increase abundance but still lose species richness – Davis and Philips 2005 find so in dung beetles, Hassall et al 2006 in isopods, Glor et al 2001 in lizards and Danielsen and Heegaard 1995 in bats.[22][23] The very unusual exception is bees, which Liow et al 2001 find lose abundance but gain species diversity in oil palm.[22][23]
