Between 1999 and 2010, a total of 302 projects on biological invasions were supported by the National Natural Science Foundation (NNSF). There has been a trend of rapid increase in the projects funded and the expenditure budgeted, from 8 projects (total 0.9 millin RMB) in 1999 to 69 projects (18.4 million RMB) in 2010. The number of funded projects was unevenly distributed in different disciplines: most of them (123 projects) were in plant protection, followed by 82 projects in ecology, which account for 67.9% of the number of projects and 66.3% of the total budgets. The major focus of investigation included 22 species of microorganisms, 26 species of animals and 24 species of plants. The NNSFfunded projects in bioinvasions have been mainly implemented by the national research institutes and universities located in the northern, eastern, and southern provinces of China, which is interestingly associated with the geographical distribution of invasive alien species.
