Abstract

In Australia, pastoralists, not-for-profit, and government organisations are managing stands of open woodland to conserve threatened species' habitats. These land areas are usually larger than a cropping field but smaller than many National Parks in Australia. In this age of broad-scale satellite remote sensing of Earth and its environment, the question is: can free, high-resolution satellite imagery provide as much efficacy for vegetation trend monitoring as commercial ultra-high spatial resolution imagery? We undertook a spatial analysis of several pairs of Maxar WorldView (WV) and European Space Agency (ESA) Sentinel-2 (S2) images and two ‘paddock scale’ properties with the budget-strapped threatened species' habitat manager in mind. We found moderate to strong correlations comparing image data sets for standard vegetation health indices (NDVI, NDRE and LAI). We conclude that the habitat manager can streamline their threatened species open-woodland monitoring budget using Sentinel-2 images for vegetation assemblage health trend monitoring.

考虑到动物栖息地管理者，评估植被健康的卫星监测

在澳大利亚，牧民、非营利组织和政府组织正在管理开放林地的林分，以保护受威胁物种的栖息地。这些土地面积通常比农田大，但比澳大利亚的许多国家公园小。在这个对地球及其环境进行大规模卫星遥感的时代，问题是：免费的高分辨率卫星图像是否能像商业超高空间分辨率图像那样有效地监测植被趋势？考虑到预算紧张的濒危物种栖息地管理人员，我们对Maxar WorldView （WV）和欧洲航天局（ESA） Sentinel-2 （S2）的几对图像和两个“围场尺度”属性进行了空间分析。通过比较标准植被健康指数（NDVI， NDRE和LAI）的图像数据集，我们发现了中等到强的相关性。研究结果表明，利用Sentinel-2遥感影像进行植被组合健康趋势监测，可以简化生境管理者对受威胁物种的监测预算。

期刊介绍： Ecological Management & Restoration is a peer-reviewed journal with the dual aims of (i) reporting the latest science to assist ecologically appropriate management and restoration actions and (ii) providing a forum for reporting on these actions. Guided by an editorial board made up of researchers and practitioners, EMR seeks features, topical opinion pieces, research reports, short notes and project summaries applicable to Australasian ecosystems to encourage more regionally-appropriate management. Where relevant, contributions should draw on international science and practice and highlight any relevance to the global challenge of integrating biodiversity conservation in a rapidly changing world. Topic areas: Improved management and restoration of plant communities, fauna and habitat; coastal, marine and riparian zones; restoration ethics and philosophy; planning; monitoring and assessment; policy and legislation; landscape pattern and design; integrated ecosystems management; socio-economic issues and solutions; techniques and methodology; threatened species; genetic issues; indigenous land management; weeds and feral animal control; landscape arts and aesthetics; education and communication; community involvement.
