The South China-Vietnam subtropical evergreen forests ecoregion (WWF ID: IM0149) covers the mountainous coastal region of southeastern China and northeastern Vietnam.

[1][2][3] The ecoregion stretches from the northeastern corner of Vietnam, across the lower half of southeastern China, and down into coastal Hainan Island.

The ecoregion runs across the southern half of Guangxi and Guangdong Provinces, with the major Guangzhou/Shenzhen/Hong Kong urban area in its east.

Temperature regimes in the north have a strong seasonality, with cool winter conditions and hot and humid summers.

[6] The forests of the area are under pressure from the increase in rubber and pulp plantations, and commercial agricultural crops in the understory.
