Worm Charming at Porthkerry
Published Monday 18 January 2016
Porthkerry Wildlife Rangers met on Saturday to have a go at worm charming. Despite the very cold weather the survey was a great success!
The group were taking part in an OPAL Soil and Earthworm Survey. The Open Air Laboratories (OPAL) network is a UK-wide citizen science initiative that allows you to get hands-on with nature, whatever your age, background or level of ability.
The survey improves our knowledge of earthworms and the soils they live in – something we know surprisingly little about.
The group found 25 worms in a 20cm square block, which Mark (the maths expert) used to work out that there were around 200million worms in the whole of the park!
Earthworms are extremely important and play a vital role in recycling plant nutrients and aerating the soil.
The group celebrated their successful survey by roasting some tasty marshmallows on the fire!
