Forest structure, composition and bird counts in windblown and control sites in Kielder Forest, Northumberland, UK, May-July 2022

Data containing information on a study of the impact of Storm Arwen on biodiversity and forest structure of Kielder Forest (Northumberland), May-July 2022. The following are included: (i) fallen timber found along 100 m transects (species, tree circumference, and whether it was flat on the ground); (ii) trees found inside 10x10-m plots (species; diameter at breast height [DAP]; status [alive vs dead]; and whether the tree was still standing); (iii) plant cover and richness in 2x2 m quadrats (Braun-Blanquet cover and plant species present); (iv) spatial data (GIS layers and buffers around survey and sampling sites); and (v) bird point counts (species detected and distances to each individual recorded) Surveys were conducted at twelve control-impact pairs (24 sites in total), whereby impact sites were those severely affected by Storm Arwen. Within each site, we carried out one 100 m transect, three 10x10 m plots, three 2x2 m quadrats, and two to four bird point counts depending on the size of the site

本数据集包含对2022年5月至7月期间凯尔德森林（诺森伯兰郡）遭受阿文风暴影响的生物多样性和森林结构的研究数据。具体内容包括：（i）在100米样带上发现的倒木（树种、树围以及是否平坦地躺在地上）；（ii）在10x10米样方内发现的树木（树种、胸径[DBH]、状态[存活或死亡]以及树木是否仍站立）；（iii）2x2米样方内的植被覆盖度和物种丰富度（ Braun-Blanquet 覆盖度和存在的植物物种）；（iv）空间数据（GIS图层和调查及采样点周围的缓冲区）；以及（v）鸟类点计数（检测到的物种及每个个体的距离记录）。调查在12对控制-影响样本（总计24个地点）中进行，其中影响样本是指遭受风暴阿文严重影响的地区。在每个地点内，我们进行了一次100米样带、三个10x10米样方、三个2x2米样方，以及根据地点大小进行两个至四个鸟类点计数。
