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.

This dataset contains measurements of greenhouse gas exchange (carbon dioxide and methane) over a plantation forest on peat, in the Flow Country, Caithness and Sutherland. It contains eddy-covariance and associated meteorological and pedological measurements from 2016/01/01 to 2017/12/31 at half hourly intervals. The time series has been gap filled to allow the calculation of annual budgets for carbon exchange.

Here we collate a database of all known birds, bryophytes, fungi, invertebrates, lichens and mammals that use Sitka spruce (Picea sitchensis) in the UK. Sitka spruce is the most commonly planted commercial tree species in the UK. In total 564 species are listed in the database. For each species we provide a level of association with Sitka spruce, ranging from obligate (only found on Sitka spruce) to cosmopolitan (found on a wide range of other tree species). Data on the ecology of each Sitka spruce associated species were collated: part of tree used, and use made of tree (feeding, roosting, breeding). Data on use or otherwise of 34 other tree species were also collated for each of the 564 species.

This dataset contains 13C and 15N data for organic soil profiles (organic horizons to top of E horizon) at two of the MOORCO experimental tree planting sites in North East Scotland (Glensaugh and Ballogie). Data also includes total soil carbon and nitrogen stocks and bulk density. Full details about this dataset can be found at https://doi.org/10.5285/00acbdb2-1eba-4016-9e50-e3126933a541

The dataset looks at Fungal hyphal in-growth into sandbags at two of the MOORCO experimental tree planting sites in North East Scotland (Glensaugh and Ballogie). The MOORCO experiment is an experimental tree planting project established on heather moorland in North East Scotland in 2005 to study the impact of woodland expansion on heather-dominated moorland. MOORCO is managed by the James Hutton Institute. The data in this file relate to fenced experimental plots (part of the MOORCO-BIG experiment) planted with Birch (Betula pubescens) and Pine (Pinus sylvestris) trees at 1m spacing, as well as unplanted heather controls. The treatment replication level is n = 4 at Glensaugh and n = 3 at Ballogie. Full details about this dataset can be found at https://doi.org/10.5285/ef1fb0e7-0c61-4d06-bbde-719f586cb1be

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).
