A mosaic of mountains, plains and hilly lands characterizes the geomorphology of the province. Vegetation varies from north to south. In the north, the Nanling Mountain Ranges is covered by the subtropical montane evergreen broadleaved forest; in the middle, it is the subtropical evergreen broadleaved forest, and in the south, the tropical monsoon forest.

Standing volume reaches 351 million m3 and the general annual growing volume 17.42 million m3. As the result of wood volume growth exceeding the general annual wood consumption of 6,750,000m3, the forest resources recycle in a good way, and the forest coverage hits 57.3% at present.

Urban "green rate" reaches 33.7%, with 7.14 m2 open green land per person. Cities including Shenzhen, Zhuhai, Zhongshan and Huizhou and dozens of townships have been awarded national medals for their excellent performance in afforestation.
