Mean daily flow and water chemistry data collected from the Tarland Burn, recorded between 2000-2010. Water chemistry determinands measured include: total dissolved phosphorus (TDP), soluble reactive phosphorus (SRP), total phosphorous (TP), particulate phosphorus (PP), nitrate (NO3-N), ammonium (NH4-N) and suspended sediments (SS); water chemistry measurements are in units of mg l-1 for all determinands. Sampling for water chemistry took place at a weekly frequency between 2000 and the end of 2003, with some daily sampling during rainfall events. Daily samples were then collected between February 2004 and June 2005. After June 2005, infrequent irregular sampling took place, with fewer determinands. Mean daily flow, in m3s-1, was also recorded. The Tarland Burn is a tributary of the River Dee (northeast Scotland). The samples were collected at Coull (WGS84 57.111, -2.810; OSGB 351050, 802540).

The dataset contains information from 234 trees at six sites across the UK collected in 2018. The tree species studied were Acer pseudoplatanus (sycamore), Castanea sativa (sweet chestnut), Fagus sylvatica (beech), Fraxinus excelsior (common ash), Quercus cerris (Turkey oak), Q. petraea (sessile oak), Q. robur (pedunculate oak), Q. rubra (red oak) and Tilia x europaea (common lime). The presence of all lichens and bryophyte species on the trunk to a height of 1.75m were recorded in addition to the presence of the lichens on branches and twigs where these were accessible. The bark characteristics recorded were bark pH, ridge and furrow width, furrow depth, hardness, water holding capacity and the bark patterning. The soil variables studied were: nitrogen mineralization and decomposition rate, total soil carbon and nitrogen, loss on ignition, soil pH and soil temperature. Fourier-transform infrared (FTIR) spectroscopy data from the soil samples is also presented along with data on site location and the habitat characteristics surrounding the sampled trees.

Data comprises abundance measures of mites, collembola and plant biomass collected from a field experiment based at Sourhope. Experimental plots varied in nitrogen addition treatment and level of ground disturbance. The data were collected as a component of the NERC Soil Biodiversity Programme, established in 1999 and centred upon the intensive study of a large field experiment located at the Macaulay Land Use Research Institute (now the James Hutton Institute)'s farm at Sourhope in the Scottish Borders. During this time, the site was monitored to assess changes in aboveground biomass production (productivity), species composition and relative abundance (diversity).

Data comprise numbers of soil microarthorpods (mesofauna) extracted over 10 days from soils in northern, subarctic Sweden sampled on 29th July 2019. Soils were sampled from treeline mountain birch forest and stands of tundra willow that were wither 'girdled' (connection between leaves and roots cut by disrupting the phloem transport) or ‘control’ (no treatment), two years prior.

Woodland vegetation data from the UK Environmental Change Network (ECN) terrestrial sites. These data are collected at all of ECN's terrestrial sites using a standard protocol (see Supporting documentation). This survey is conducted when plots surveyed during the coarse-grain survey fall in woodland. Seedlings, diameter at breast height (dbh), height and species dominance are recorded within a surrounding 10m x 10m plot. ECN is the UK's long-term environmental monitoring programme.
