Fig. 3.

The relative frequency with which landscapes containing different proportions of urban landcover were sampled in 2020 compared to 2019. In red (or the darkest shade of grey in greyscale reproduction) are the proportions of urbanization that were more frequently sampled in 2020, relative to 2019. In the data from Portugal, Spain and California, more urbanized landscapes were sample at higher frequency in 2020 than 2019. Qualitatively similar results were found when the data from 2020 were compared to data from years prior to 2019.
