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.

Data comprise flower abundance and diversity data and bee abundance, diversity and activity data collected during extensive surveys carried out on farms in Hampshire and West Sussex, southern England between 2013 and 2015. The pollen diets of wild solitary bees were quantified using direct observations and pollen load analysis. The purpose of the study was to provide valuable information to scientists, governments and land managers in designing more effective measures to conserve the broader wild bee community on agricultural land. The work was funded by the Natural Environment Research Council grant NE/J016802/1 and the Game and Wildlife Conservation Trust.

The data set contains fluxes of nitrous oxide (N2O) from Whim peatbog in central Scotland, measured using chamber methods. A nitrogen deposition experiment was carried out at the site, where nitrogen was applied in different forms (ammonium, nitrate, and ammonia) at doses from zero to ~100 kg N per ha per year. Flux measurements were made over a six month period starting at the end of March, 2012. The experiment was begun in 2002 under the NERC Global Nitrogen Enrichment (GaNE) programme, and continued under various funding sources. This work was supported by the Natural Environment Research Council award number NE/R016429/1 as part of the UK-SCAPE programme delivering National Capability.

Fungal community DNA was sequenced from soils in northern, subarctic Sweden. 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), 0, 1 and 2 years after the treatment was applied.
