Study Notes

Rainforest Conservation in China

  • Tropical rainforests exist in China, notably in Xishuangbanna, Hainan Dao, and parts of Guangxi and Xizang.
  • These regions are the northernmost limit of South-east Asian tropical rainforest areas.
  • Xishuangbanna is the largest area of tropical rainforest in China, recognized internationally.
  • Hainan Dao has a large, continuous area of tropical rainforest, considered the most concentrated and best-preserved in China.
  • Tropical rainforests in China are located in frost-free, hot and humid southern regions.

Distribution of Tropical Rainforests in China

  • Xishuangbanna, a region in southern Yunnan, contains approximately 90% of China's rainforest area in mountainous terrain.
  • Hainan Dao, an island, has a land area of 6,593 km².
  • Scattered rainforest patches exist in southwest Guangxi and southeastern Xizang river valleys.

Characteristics of Xishuangbanna Rainforest

  • 19,223 km² area
  • Mostly mountainous, around 600m above sea level.
  • Tropical monsoon climate (long, hot summers, mild winters)
  • High rainfall (over 1,500mm), concentrated in the summer.
  • Supports diverse plant and animal life (over 5,000 plant species and 2,000 animal species).
  • Home to Wangtianshu (sky tree), China's tallest tree.
  • Contains last few hundred Asian elephants.

Characteristics of Rainforest on Hainan Dao

  • 6,593 km²
  • Ranges in elevation from 40m to over 1,800m.
  • Known tropical montane rainforest areas above 800m.
  • Maritime tropical monsoon climate; long hot summers; short mild winters; high summer rainfall (over 1,653mm).
  • High biodiversity, including over 4,600 plant species (15% of China's total), 600 endemic.
  • Contains over 570 animal species.
  • Home to a rare species: Hainan gibbon.

Problems Facing Chinese Rainforests

  • Primary forest area in southern China has been declining over recent decades.
  • Xishuangbanna and Hainan Dao have lost significant areas of primary forest (12,502 and 9,428 hectares respectively between 2002-2022).
  • Deforestation is driven by demand for cash crops, timber, and paper.
  • Eucalyptus, rubber, and tea plantations are replacing rainforests in southern China.

Measures to Conserve Rainforests

  • Protected areas and national parks are established to maintain rainforest integrity and protect endangered species.
  • Stricter enforcement of forestry laws is in place to prevent illegal logging and regulate timber use.
  • Initiatives like the Natural Forest Protection Project aim to preserve valuable, naturally occurring forests and to increase rainforest area by promoting reforestation.
  • Conversion to multi-species and multi-layered plantations is encouraged to promote sustainable rainforest conservation.
  • Individuals can contribute by consuming fewer rainforest products and supporting sustainable forest practices.
