TERN Alice Mulga SuperSite Five Photopoint Image Collection

High quality digital site reference images are captured for the core 1 hectare vegetation plot of the site on an annual basis to provide context for researchers to understand the general layout and vegetation of the study site, and as a visual reference to monitor any changes over time. Photopoints will be taken annually using the five point photopoint method. The set of images for each year usually consists of twenty images: four images taken at each corner of the plot facing each of the four cardinal points, and four images taken from the centre of the plot facing each corner.

The Alice Mulga SuperSite was established in 2010 at Pine Hill Cattle Station with research plots located in low open woodland Mulga (Acacia aneura) and non-Acacia, hummock grassland, and river red gum forest. The core 1 ha plot is located in a dense Mulga woodland (cover 70–80%). For additional site information, see https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/alice-mulga-supersite/ .

Other images collected at the site include digital cover photography, phenocam time-lapse images taken from fixed under and overstorey cameras, panoramic landscape and ancillary images of fauna and flora.

本数据集每年为研究样地的核心1公顷植被样地采集高质量数字化基准参考影像，旨在为研究人员明晰研究样地的整体布局与植被特征提供背景参照，同时作为可视化素材用于长期监测样地的时序变化。研究采用五点摄影点法（five point photopoint method）每年开展拍摄工作：年度影像集通常包含20张影像，分别在样地四个角点各拍摄4张，对应东、南、西、北四个方位基点；另在样地中心拍摄4张，分别朝向四个角点。

爱丽丝Mulga超级监测样地于2010年在派恩希尔畜牧站设立，其研究样地分布于多枝相思（Mulga，Acacia aneura）低矮开阔林地、非金合欢属丘状草原以及河岸赤桉林生境中。本次描述的核心1公顷样地位于盖度70%~80%的密集多枝相思林地内。如需获取该样地更多详细信息，请访问：https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/alice-mulga-supersite/

该站点采集的其他影像类型还包括数字化植被盖度摄影影像、由固定林下层与林上层相机获取的物候相机（phenocam）延时影像、全景景观影像以及动植物配套辅助影像。
