Dataset of "Vegetation cover estimation in semi-arid shrublands after pre-scribed burning. Field-ground and UAV comparison"

This dataset belongs to the experiment carried out in Sierra Filabres (Almería) to explore the effects of prescribed burns and pyric herbiroy on Mediterranean shrubland communities. <br> This dataset contains data relative to the comparison between the estimation of plant coverage using a multispectral camera on a Remotely Piloted Aircraft System (RPAS), and the plant coverage estimated using ground-truth methods (traditional way). The dataset includes the total coverage for 96 plots within two areas (two treatments) usging the RPAS and using the traditional method. For each of the 96 several fields are included: date: date of the field and RPAS measures quadrat_name: id of the quadrat. cover_type_infoca: an internal classification of the covert type (not used) plant_coverage_field: the estimated plant coverage by traditional methods. plant_coverage_rpas: the estimated plant coverage by RPAS. shannon: the Shannon-Wiener index (plant diversity) richness: number of total plant species per quadrat slope: the terrain slope (in percentage) treatment: the treatmen where the plots were set. cover_type: the cover type considered in the study. This experiment belong to the LivingLabs developed in this area to explore the role of pastoralism in the conservation of the biodiversity. <br>

本数据集源自西班牙阿尔梅里亚省锡拉弗拉布雷斯（Sierra Filabres）开展的野外控制实验，旨在探究计划火烧（prescribed burn）与火调控牧食（pyric herbivory）对地中海灌丛群落的影响。
本数据集包含两类植物覆盖度估算结果的对比数据：一是通过遥控无人机系统（Remotely Piloted Aircraft System, RPAS）搭载多光谱相机（multispectral camera）获取的估算值，二是采用地面实况调查法（传统手段）得到的估算值。数据集涵盖了两个试验区域（两种处理组）内共96个样地的相关数据，分别记录了无人机法与传统方法下的总植被覆盖度。针对每个样地，每条数据记录包含以下字段：
- date：野外调查与无人机航测的日期
- quadrat_name：样方编号
- cover_type_infoca：植被覆盖类型内部分类（本研究未使用该字段）
- plant_coverage_field：传统地面调查法估算的植物覆盖度
- plant_coverage_rpas：无人机系统法估算的植物覆盖度
- shannon：香农-威纳多样性指数（Shannon-Wiener index），用于表征样方植物多样性水平
- richness：样方内植物物种丰富度，即样方中总植物物种数
- slope：地形坡度（单位：百分比）
- treatment：样地所属的试验处理组
- cover_type：本研究中考量的植被覆盖类型
本实验隶属于该区域实施的LivingLabs研究计划，旨在探究牧食作用在生物多样性保护中的作用。
