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. Full details about this dataset can be found at https://doi.org/10.5285/f1fd1790-0cc0-45ea-8dda-8258d23e88b1
