[This dataset is embargoed until November 15, 2024]. 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 Full details about this dataset can be found at https://doi.org/10.5285/9f914e5b-958d-49a8-a5bf-86c35d865257

The dataset consists of solute concentrations (Potassium, Calcium, Magnesium, Iron, Sodium, Aluminium, Phosphate, Nitrate, Ammonium, Chlorine, Sulphate), also pH and suspended solids, in waters sampled from clear felled and standing Sitka spruce (Picea sitchensis) forest ecosystems in Kershope Forest, Cumbria, UK. Water samples were collected from the ecosystem of a Sitka spruce plantation at weekly intervals for six years. The drainage system of the site had been designed to divide the plantation into a series of artificial catchments, three of which were designated experimental plots and clearfelled in the second year of sampling while three others were the control plots which remained unfelled until the end of the study. This work formed part of a programme of field and laboratory work to determine the effects of felling plantation forest on soil processes. Samples were collected by staff from the Institute of Terrestrial Ecology (ITE) between 1981 and 1987.
