Hibernaculum

1. The site we chose - in the North West corner of the churchyard, on an open, sunny bank
2. Bob and Tom mark out the base and start digging. We leave the hole covered in branches as the rain pours down

3. Resume digging - as we reach 40 cm we hit sticky red clay

4. Ed and Norman digging down removing bramble roots

7. Once the hole was filled with rubble and wood we started to backfill - inserting two short drainpipes to give access to the interior.
8. All the soil which was dug out was put back on top of the stone and branches. We tapped it down firmly and then laid the turf we had removed on top.

9. Luckily the rain had kept the turf moist and with luck it will grow strongly, stabilising the Hibernaculum

10. The Hibernaculum blends well into the bank. Hopefully a lizard or two will overwinter here.
