What’s living in your hedge?
Take part in the OPAL biodiversity survey and uncover the diverse range of wildlife in our hedges. You’ll contribute to valuable research and learn more about the importance of hedges and how you can improve them.
Hedges support many animals by providing them with food and shelter. Berries and seeds are food for birds, while holes beneath the hedge are often home to small mammals. You’ll also discover caterpillars, shieldbugs and many other invertebrates living among the leaves.
By telling us what you find, we can instantly rate the condition of your hedge and offer suggestions on how to improve it.
How to take part
Step 1: Download the easy-to-follow instructions and guides below. You can skip this step if you've already received one of our biodiversity survey packs.
Step 2: Find a suitable hedge to carry out the survey and answer the questions in the workbook. Use our guide to help you identify the invertebrates you might find.
Step 3: Submit your results using our simple online form.
Please show care and respect to our environment.
Many animals rely on hedges for food and shelter.

Water survey - join in now
How healthy is your local lake or pond?
By taking part in the OPAL water survey, you’ll help scientists learn more about how polluted our lakes and ponds actually are – something we know surprisingly little about.
Good water quality is essential for the many animals and plants that live in and around our lakes, ponds and rivers. Unfortunately, water is easily affected by pollution from agriculture and industry, waste we throw away, and even pollutants in the air.
Look for clues in the water
Animals living in the water can tell us a great deal about how polluted the water may be. Some species struggle to survive in polluted waters, while others are more tolerant. By telling us what life you see in your local pond you’ll discover more about the water's health and contribute to valuable scientific research.
Please show care and respect to our environment.
Ponds and lakes are home to many important creatures.
Simple tests for water clarity and pH, will provide further clues to the water quality.

It's easy to join in. Start by downloading our free survey pack, which includes full instructions and identification guides.
Submit your results
Once you've completed the survey, please take the time to submit your results using our simple online form. Your results are important to us, even if you didn't manage to finish all the activities.

Wonderful world of worms
A few months ago I knew next to nothing about earthworms - not a great situation to be in considering part of my job is to help groups do the OPAL Soil and Earthworm survey!
So I decided I'd better swat up. Lucy, who works for OPAL at the NHM , kindly pointed me in the direction of UCLAN Earthworm Research Group - this website has some great photographs of earthworms and some fascinating wormy facts.
The UCLAN website whet my appetite for earthworms (not literally, I hasten to add), so I got a couple of books out of the library on worms, and learnt a bit more about these amazing creatures. Did you know that they have 5 hearts? I guess this is because they are very long in relation to their thickness, and it must be hard work pumping blood all the way to their back end.
Another interesting fact is that earthworms can live for 4-6 years! Sadly the common belief that an earthworm cut in half makes two earthworms isn't actually true, and unfortunately we've chopped quite a few in half whilst doing the OPAL survey! Sometimes the head end of the worm will survive, if it hasn't been too badly damaged, and they can actually regrow some of their segments, which I think is pretty impressive!
As the ground warms up, worms become more active, so if you've not already done your OPAL survey, now is the time to get out and discover these amazing creatures!

Chris Packham helps launch the soil and earthworm survey
Wildlife presenter Chris Packham helped launch the soil and earthworm survey this week in Kensington Gardens, London.
Chris joined children from St Albans School to take part in the study, the first of five OPAL surveys that ask the public to contribute to important scientific research.
Chris Packham said: “Earthworms are really undervalued and few people realise the important job they do keeping the soil under our feet nice and healthy. Surprisingly little is known about the different species or their habitats, so this research will be vital to help scientists understand how earthworms are affected by pollutants in the soil and by human activity.”
Anyone can take part in the soil and earthworm survey. All you need to do is download a survey workbook and field guide from the OPAL site. These contain everything you need to know to take part.
Once you’ve completed the survey, you can upload your results onto the OPAL website and see your contribution instantly on our interactive map.
Supporting information for groups
Group leader survey support pack
This pack provides a range of advice and ideas for carrying out the soil and earthworm survey with your group. This includes:

The survey begins!
The soil and earthworm survey has begun. You can now take part in one of the nation’s biggest public nature surveys and learn all about earthworms and the world they live in.
Your results will help scientists build a national record of earthworm populations and soil types across England.
Everything you need to take part, including full instructions and an earthworm identification key, can be found on the website.
Once you’ve completed the survey, upload your findings onto the OPAL website and you'll be able to view your contribution on our interactive map.
If you want to learn a bit more about earthworms before you head out into the field, check out our online earthworm guide, which includes profiles on all the earthworms being recorded in the survey.
We hope you enjoy taking part in this survey.
Survey events
Some of the OPAL regions are organising public events where you can take part in the survey and benefit from expert guidance and knowledge. Be sure to check your regional page to see what’s happening near you.
