River Red Gum Fauna 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\nData were collected for four fauna components, as described below:\r\n\r\n__Bat Activity__: Bat activity was surveyed within each 9 ha plot using ultrasonic recordings of bat calls over three consecutive nights, around the time of a new moon, in summer. Surveys were undertaken annually over seven years. Recordings were processed through Anascheme to identify bat activity by species.\r\n\r\n__Bird Abundance__: Birds were surveyed in a 2 ha subplot within each 9 ha plot, six times over seven years. In each survey year, visual and auditory observations were recorded by an experienced observer during four separate 20 minute periods. \r\n\r\n__Fox Scats__: Fox scat data were collected in three 20 m x 20 m subplots within each 9 ha plot, six times over seven years. The number of fox scats was counted, with any uncertain specimens subsequently confirmed by a scat analysis expert.\r\n\r\n__Glider Feed Trees__: Glider feed trees were surveyed visually by traversing each 9 ha plot and recording the number of trees with distinctive glider feeding notches. Data were collected twice over seven years. \r\n\r\nFurther information is provided in the reference guide for each dataset.\r\n

本数据集采集自**河红桉生态疏伐试验（River Red Gum Ecological Thinning Trial）**，数据集详情可参见：https://datasets.seed.nsw.gov.au/dataset/river-red-gum-ecological-thinning。

本次采集的数据涵盖四类动物类群，详情如下：

**蝙蝠活动（Bat Activity）**：于夏季新月前后的连续三晚，在每个9公顷（ha）样地内通过超声录制蝙蝠叫声的方式开展蝙蝠活动调查。该调查每年开展一次，持续七年。录制的音频经Anascheme软件处理，以按物种识别蝙蝠活动情况。

**鸟类丰度（Bird Abundance）**：在每个9公顷（ha）样地内选取2公顷（ha）的副样地开展鸟类调查，七年期间共开展六次调查。每个调查年度内，由经验丰富的观测者分四段独立的20分钟时段，记录鸟类的视觉与听觉观测数据。

**狐狸粪便（Fox Scats）**：在每个9公顷（ha）样地内设置三个20米×20米的副样地收集狐狸粪便数据，七年期间共开展六次调查。调查人员计数狐狸粪便的数量，对存在鉴定疑问的样本，后续将由粪便分析专家进行确认。

**滑翔类有袋类取食树木（Glider Feed Trees）**：通过遍历每个9公顷（ha）样地的方式开展目视调查，记录带有特征性滑翔类有袋类取食刻痕的树木数量。该数据采集工作在七年期间共开展两次。
