Today I went for a short hike around an area just over the Yorkshire border not too far from where I live. This area mostly consists of open heather moorland and the Viviparous lizard (Zootoca vivipara) can be found throughout this area, although usually in small densities. In a bracken covered, humid valley I found 10 or so lizards in half an hour, include tiny neonates, to adult gravid females. This is probably the highest number of lizards I have seen during one visit in my local area.
