We have established two nation-wide databases on nature reserves and species distribution, documented nearly 380,000 entries of 1,985 species, carried out 3,156 monitoring activities, recruited and trained more than 200 volunteers, and have uploaded simulated habitat maps for 4 species as well as of 474 national nature reserves. The “Nature Watch” website (chinanaturewatch.org) and mobile phone app enable the public to view biodiversity data and make individual contributions. At present, the system has 4,282 registered users and 107 free downloadable datasets and sources of literature.
