Yasuní Forest Dynamics Plot, Ecuador

Yasuní National Park in eastern Ecuador appears to be one of the most biologically diverse sites in the Amazon Basin. The Pontificia Universidad Católica de Ecuador, the University of Aarhus in Denmark, and CTFS/STRI initiated a Forest Dynamics Plot along the Rio Tiputini in Yasuní, Napo Province in non-seasonal, old-growth lowland moist forest in 1996. Within one hectare at the Yasuní FDP, there are 644 species. Comparing this number with species counts in one hectare at other plots -- Panamanian plot has 168 species and plot on peninsular Malaysia has 497 species --the richness of this area becomes even more apparent. When the 50-ha plot is censused, we expect that there will be about 1,300 species in the plot. A socio-economic study on the local Waotani community was conducted near the site, and found that distance from large markets is inversely related to non-timber forest product use.

厄瓜多尔东部的亚苏尼国家公园（Yasuní National Park）堪称亚马孙流域生物多样性最为丰富的区域之一。1996年，厄瓜多尔天主教大学（Pontificia Universidad Católica de Ecuador）、丹麦奥胡斯大学（University of Aarhus）以及CTFS/STRI，在纳波省亚苏尼地区提提尼河沿岸的一片非季节性原始低地湿润森林中，设立了森林动态样地（Forest Dynamics Plot，FDP）。在该亚苏尼FDP的1公顷样方内，共记录有644个物种。将这一物种数量与其他样地的公顷物种数进行对比：巴拿马样地仅含168个物种，马来西亚半岛样地则有497个物种，该区域的物种丰富度优势由此愈发凸显。待这片50公顷的样地完成普查后，预计样地内的物种总数将达到约1300种。此外，研究团队还在样地附近针对当地瓦奥达尼社区（Waotani）开展了社会经济学调查，结果显示：与大型集市的距离与非木材林产品的利用程度呈负相关关系。
