LBA-ECO LC-21 Foliar Nutrients, Logged Areas, Tapajos Forest, Para, Brazil: 2003

This data set provides measurements for foliar nutrients from logging blocks in the Tapajos National Forest, Para Western Santarem, Brazil. Data are included for calcium (Ca), phosphorus (P), magnesium (Mg), nitrogen (N), and potassium (K) concentrations. In March 2003 foliar samples were collected from the cover types remaining after selective logging in 2002: forest, tree-fall gaps, skids, roads, and deck areas. Fresh foliage was also collected in March 2003, from 192 upper canopy species at an intact forest site 17 km from the logging area.

There are two data files with this data set.

本数据集提供了巴西帕拉州桑塔雷姆西部塔帕约斯国家森林公园内伐木地块的叶面营养素测量数据。数据包括钙（Ca）、磷（P）、镁（Mg）、氮（N）和钾（K）浓度。2003年3月，从2002年选择性伐木后剩余的植被类型中采集了叶样，包括森林、树倒空地、伐木道、道路和甲板区域。此外，在同一年的3月，从距离伐木区17公里的完整森林地点采集了192种上层冠层物种的新鲜叶片样本。本数据集包含两个数据文件。
