From the longer time series (2009–2015) available from seven data loggers, five showed a positive trend in minimum soil temperature (1‐ALZ west, 3‐SIN south, 4‐ISA east, 4‐ISA south, 4‐ISA west, with R 2 = 0.6, 0.2, 0.3, 0.2, 0.5, respectively), whereby 1‐ALZ west was marginally significant ( p = 0.06), and four showed a positive trend in mean temperature (1‐ALZ south, 3‐SIN west, 3‐SIN south, 4‐ISA west, with R 2 > 0.2).
