The data include daily soil temperature, ground temperature, and ambient temperature in Celsius and soil volumetric moisture in percent between 2019 and 2022, collected from 15 plots across Wytham Woods, near Oxford in southern England. These cover three different habitat types representing different levels of ash dieback: ash dominated and girdled, ash dominated, and non-ash dominated. Soil and ground microclimate (temperature and volumetric moisture) were recorded at 15-minute intervals, and averaged to daily resolution. The data contributed to a project on the ecological impact of ash dieback.

Provenance & quality
Soil and ground microclimate (temperature and volumetric moisture) were recorded at 15-minute intervals between 2019 - 2022 using five TOMST TMS-4 loggers in each plot. The raw soil moisture counts were converted to volumetric moisture (%) using conversion factors provided by TOMST based on soil type (a link to the conversion pdf is provided). All data were averaged to the hour and then averaged again to the day. This provided daily temperature and moisture means which are reported here.
The temperatures are provided in Celsius and moisture in water content per unit volume in percent.
Limitations include logger breakage which sometimes limited the data available from each plot. Therefore, not all plots have consistent data from five intact loggers. The raw moisture count conversion is dependent on soil type. We analysed the soil's physical composition in each plot and used the model that most closely aligned with our site. Errors associated with model performance is likely to have over- or underestimated the values, however, overall, the high volume of data provides a robust understanding of hydrology across the plots.
