The 25 ha Baotianman Forest Dynamics Plot (BTM) was established in 2009 and located in Baotianman National Natural Reserve in Nanyang region of Henan Province, China. The Baotianman Reserve is one of few reserves to protect natural forests and wild animals in the transition zones between warm temperate zone and subtropical zone in Central China. The annual average temperature of Baotianman is 15.1°C. The mean annual rainfall is 885.6 mm. The Baotianman plot is dominated by the temperate deciduous broadleaved forest. The topography in the Baotianman plot was measured by the electronic total station. A total of 59,569 stems of tree and shrub with DBH (diameter at breast height) ≥1cm were tagged, mapped and identified to species, and the abundant species are Quercus aliena var. acutiserrata, Acer grosseri, Pinus armandii, etc. The 150 seed traps, 450 1m ×1m seedling plots, and 25 infrared cameras were set up to monitor the dynamics of seed rain, seedling, and animal in the Baotianman plot.
The Baotianman plot establishment was funded by National Science and Technology Support Plan (2008BAC39B02). Thanks to hundreds of college students, graduate students, local workers, and researchers for their hard works. Thanks to State Key Laboratory of Vegetation and Environmental Change, Institute of Botany, the Chinese Academy of Sciences, Chinese Forest Biodiversity Monitoring Network, Henan Agricultural University, Nanyang Normal University, China University of Mining & Technology (Beijing), Pingdingshan University, and Baotianman National Nature Reserve for their cooperation and kind support.
