River Red Gum Litter and Woody Debris Data

These data were collected as part of the [River Red Gum Ecological Thinning Trial](https://datasets.seed.nsw.gov.au/dataset/river-red-gum-ecological-thinning). \r\n\r\nLitter depth, litter cover and woody debris were recorded. The following methods were employed:\r\n\r\n__Litter Cover and Litter Depth__: Litter cover and litter depth data were collected within three 20 m x 20 m subplots within each 9 ha plot. Litter was defined as any disconnected dead plant material from 1-99 mm in diameter. Average litter depth within each subplot was estimated by measuring litter depth at 10 locations using a metal ruler and cardboard disk. Litter cover was visually estimated as percentage within each subplot. Litter data was collected six times across seven years. \r\n\r\n__Coarse Woody Debris__: Coarse woody debris (CWD) data was collected within two 0.1 ha subplots within each plot. CWD was defined as dead plant material (log) with a diameter of 100 mm or more and at least 0.5 m in length. The midpoint diameter and length of each log was recorded. CWD was measured three times across seven years.\r\n\r\nFurther information is provided in the reference guide for each dataset.\r\n\r\nData for coarse woody debris is not publicly available.

本数据集采集自**河岸赤桉生态疏伐试验（River Red Gum Ecological Thinning Trial）**（数据集来源链接：https://datasets.seed.nsw.gov.au/dataset/river-red-gum-ecological-thinning）。

本研究记录了枯落物厚度、枯落物盖度及木质残体相关数据，具体采集方法如下：

**枯落物盖度与枯落物厚度**：在每个9公顷样地内的3个20米×20米小样方中采集枯落物盖度与厚度数据。枯落物定义为直径1~99毫米的离散死亡植物残体。通过使用金属直尺与硬纸板圆盘，在每个小样方内的10个测点测量枯落物厚度，以此估算该小样方内的平均枯落物厚度。采用目视估算法记录每个小样方内的枯落物盖度百分比。该枯落物数据在7年间累计采集6次。

**粗木质残体（Coarse Woody Debris, CWD）**：在每个样地内的2个0.1公顷小样方中采集粗木质残体数据。粗木质残体定义为直径≥100毫米、长度≥0.5米的死亡植物残体（伐倒木）。需记录每根伐倒木的中点直径与长度。该粗木质残体数据在7年间累计采集3次。
