Tree functional attributes related to forest succession after Hurricane Felix and their implications for sustainable management of forest resources in the North Atlantic Autonomous region of Nicaragua

Betwen February and August 2011, 3.5 years after Hurricane Felix hit the Atlantic coast of Nicaragua, a study was carried out to identify the response mechanisms of tree species in forests after the Hurricane. Five functional traits, that characterize tree response to disturbance caused by the Hurricane, were measured in a deciduous forests located in Santa Clara (RAAN). Soil properties were also measured for: landscape (landscape type, slope, topography, drainage); soil morphology (colour in humid conditions, texture, rock fragments, structure, consistency) and soil chemistry (pH, acidity, Ca, Mg, K, P and C). Soil samples were collected at 30cm depth in 12 plots distributed in the study area.

2011年2月至8月，即飓风费利克斯（Hurricane Felix）袭击尼加拉瓜大西洋沿岸后的3.5年，本研究开展调查以阐明森林中树木物种受飓风扰动后的响应机制。研究于坐落于圣克拉拉（RAAN）的一处落叶林内，测定了5种可表征树木对飓风扰动响应的功能性状（functional traits）。同时测定了如下土壤属性：景观因子（景观类型、坡度、地形、排水性）、土壤形态特征（湿润条件下颜色、质地、碎石含量、结构、紧实度）以及土壤化学性质（pH值、酸度、钙、镁、钾、磷及碳元素）。本研究在研究区域内布设的12个样地中，采集了深度为30cm的土壤样品。
