Abstract:
Subtropical forest degradation induced by unreasonable disturbance is closely related to human activities in Southeast China, frequent small-scale logging by local people was the dominated disturbance regime in the forest over the past decades. The objective of this research is to evaluate the demographic consequences of logging for Pinus massoniana, a pioneer species, at the individual scales (survival, growth and fecundity) and the population scales (population growth rate and size distribution) in short-term period. Individual's size was combined with vital rates using various modeling approaches based on demographic data from three annual censuses (2011-2013). Integral projection model (IPM) was constructed and used to conduct comparative demographic analyses.
The study was performed at Changting County (25°18′40″-26°02′05′N, 116°00′45′-116°39′20′E) located in the southern Wuyi Mountain in Southeast China. In 2011, one permanent plot (25°36′48″N, 116°26′18′E) approximately 30 × 30 m size was established, in which P. massoniana was the main dominant tree species. To ease data collection, the plot was subdivided into 36 subplots of 5 × 5 m. Measurements took place in the entire plot in July 2011, 2012 and 2013. For each individuals of P. massoniana, basal diameter, total height were measured and labelled during the first census. For those individuals with heights more than 1.5m, diameter at breast height (DBH) was also measured and recorded. In subsequent years, all labelled individuals were checked and re-measured, new recruits (seedlings that germination and establishment between census periods) within the plot were searched, labelled and measured. The number of produced pinecones over the studied periods were also recorded. For each individual, plant growth was calculated via subtracting the plant size in current year by the plant size in the previous year. The sample plot was logged in October 2012 after the second census. The meteorological data of Changting County (measurement site 58911 located in 25°38′20″N，116°27′28″E) was also recorded.
