Operative temperature dataset in areas with native and invasive vegetation

Operative temperature data collected in both "native areas" (native renosterveld vegetation) and "invaded areas" (native renosterveld vegetation areas invaded by alien trees, mainly Acacia saligna). The data were collected using simplified operative temperature models (OTM) of Homopus areolatus tortoises, in four field sites in the Western Cape, South Africa, at an hourly temporal resolution and during one year. For each field site, the data are from between 40 and 45 OTMs placed above- and under-ground and covering a range of microsites that varied in substrate and exposure to the sun.
