The BIG Hedgehog Map A hub for mapping the UK’s hedgehogs, and pledging to make holes for them. Part of Hedgehog Street, a national campaign to save hedgehogs by PTES & BHPS.

Did you know that in the UK, hedgehog numbers have declined by between a third and three quarters over the last twenty years? 🤔

If you've seen one recently, log it on the Big Hedgehog Map 🦔

A small lizard is emerging from the bark of an old log. Its tail and feet aren't visible. It's facing right and pointing slightly down. It's looking up as though at the camera, and its right eye is visible. There are some old bits of dead reed stems resting on the bark as well as a couple of thin pieces of dead stalk. To the left there are a few green leaves.

The unseasonably warm weather brought our Common Lizards (Zootoca vivipara) out this morning. The first we've seen so far this year! 🦎 😍

🦦Local Wildlife Sites are crucial for habitat and species protection, aiding resilience against modern pressures and climate change. Waterstock Mill in Oxon, featured in BBC's "Secret Garden" with Sir David Attenborough, highlights this.

A thin pale shiny coloured reptile (actually a legless lizard) is emerging from the cover of some grass into a bare stony area. It's moving from left to right, and its small eye is clearly visible.

Despite the low temperatures, one of our volunteers counted 16 Slow worms (Anguis fragilis) sheltering under our reptile mats yesterday. Four adults and twelve juveniles. Seems like a good start to the year!

Over recent months we’ve been running our Local Wildlife Site (LWS) panels across Berks and Oxon, reviewing sites surveyed in 2025.

LWS are non‑statutory sites of local importance for biodiversity. They are selected against locally agreed criteria and play a vital role in planning and conservation.
