計畫資料

The BID-AF2015-0038-NAC project has gathered these data that come from vegetation assessment and forest dynamic study of various areas in Gabon from 2000 to 2018. These studies have been supported by Several fundings. First by the CARPE fund, started in 2004 to assess vegetation in the national parks of Gabon. A botanical team from diffrents institutions such as ForestsResources and People, Limbe Botanic Garden, l’Herbier National du Gabon,Smithsonian Institution, Wildlife Conservation society, and the Missouri Botanical Garden was involved in order to install permanent Biodiversity Plots (BDP’s) within the national parks of Monts de Cristal and Waka (Sunderland et al. 2004; Balinga et al. 2006). Others national projects relayed to study trees diversity and forest dynamic in Gabon across the Aires-Sud 7148 project that allowed IRET to install 3 perment plots in the north of Gabon. These data were used to model spatial distribution of trees and to develop growth modelling of commercial trees (Obiang et al. 2010; Engone Obiang et al. 2012; Obiang et al. 2013; Obiang et al. 2014). But the bigest plot (25 ha) in Gabon was installed by the Smithsonian in Rabi since 2010 (Memiaghe et al. 2016). Many non permanent plots were also been installed by IRET and Herbier National du Gabon between 2011 and 2018.

取樣方法

The presented data come from either permanent or non-permanent plots. • The 1 ha permanent plots from the National parks of Monts de Cristal and Waka were established according to the standardized methodology describe in Sunderland et al (2004) and Balinga et al (2006). • The 1 ha-plots of the IRET had been divided into 100 quadrats of 10m x 10m (see Picard and Gourlet-Fleury 2008). • The 25 ha-plot of Smithsonian in Rabi was subdivided into 625 quadrats of 20 m × 20 m, with elevation recorded at the 676 grid corners. Plot establishment followed the Smithsonian-ForestGEO standard methods (Condit 1998; Anderson-Teixeira et al. 2015; Memiaghe et al. 2016). • In the non-permanent rectangular or circular plots, trees were not tagged or located. Identification of trees were done directly on the trees with dbh ≥10 cm.
