Almost 70% of the land is covered by tropical rainforest
Climate of Malaysia
Typical of tropical rainforest climates with high rainfall and high temperatures all year round
Biodiversity of Malaysian rainforest
Over 15,000 plant species, including 5,500 flowering plants and 2,600 tree species
750 bird species
250 mammal species
350 reptile species
190 amphibian species
350 fish species
1000 butterfly species
Malaysia has the fastest rate of deforestation in the world
Since 2000 an average of over 140,000 hectares of forest has been felled and cleared each year
Causes of deforestation in Malaysia
Logging
Energy
Mining
Commercial plantations
Settlements
Subsistence farming
Logging
Malaysia is the largest exporter of tropical hardwoods
Selective logging is the dominant type of logging but this requires road construction and settlements which result in deforestation
Energy
The construction of dams to provide Hydroelectric power result in flooding of large areas of forest
The Bakun Dam will result in 700km2 of land being underwater in Sarawak, Malaysia
Mining
Tin mines are widespread and require deforestation for the mine itself but also for road construction
An iron ore mine planned for the Som Forest Reserve will result in the deforestation of over 60 hectares
There is also drilling for oil and gas
Commercial plantations
Malaysia exports over 30% of the world's palm oil and is the second largest producer
Many palm oil processes now adopting a zero-deforestation policy so that they do not buy palm oil from deforested areas. However, Clear felling permits are sometimes used in Malaysia to clear land and then sometime later another company will plant palm oil
Settlements
Up to 1980 people were encouraged to move to rural areas from the cities to try and reduce the pressure on urban areas
This led to the deforestation of approximately 15,000 hectares of rainforest
Subsistence farming
This can sometimes involve slash and burn where areas are cleared using fires - these can sometimes get out of control and destroy large areas of rainforest
Effects of deforestation
Soil erosion
Loss of biodiversity
Local climate change
Global climate change
Impact on indigenous communities
Soil erosion
Without the tree roots to bind the soil, the soil is more easily eroded by wind and rain
Exposed soil is more vulnerable to leaching of nutrients and the soil becomes less fertile
Loss of biodiversity
Habitats are destroyed and the ecosystem affected by deforestation so the variety of plants and animals decreases
Oil Palm plantations lead to a 35% reduction in species
Orangutans, pygmy elephants, Sumatran Rhino and Malayan tigers are all endangered
Local climate change
Reduced transpiration and evaporation leads to a decrease in precipitation and an increase in temperatures
Rainfall patterns become less reliable and more extreme
Global climate change
Felling of the trees leads to a decrease in the absorption of carbon dioxide
Increases carbon dioxide concentrations in the atmosphere and as this is a greenhouse gas this increases human induced climate change
Use of fire for clearance also increases carbon dioxide emissions
Impact on indigenous communities
Indigenous communities such as the Orang Asli and Temiar have been forced off land
Pollination of fruits has reduced due to a decrease in pollinating insects and animals such as bats
This has reduced the available food sources
In Kuala Koh village 2019 at least 15 indigenous Batek died after an outbreak of disease possibly transmitted by loggers working near to the village
