What should I find on my plot today but... well, the clue's in the title! Luckily my bonfire was all in bought-in material, so the wee hog wasn't involved, but I think it was a bit startled to see us as it rolled up, and got itself snagged between the bars of the pallets making up my compost bin, before it eventually worked its way out and set off across the allotments at a steady pace.
I was worried, but the mother-out-law is a small mammal ecologist and she assures me that at even this time of the year if it's warm they are likely to be about - they may even move hibernation dens several times in a winter. A really nice surprise as I haven't seen a 3D, as opposed to 2D, hedgehog in over a year, and have never seen one on the plots in 15+ years out there.
