This project is a collaborative effort involving coastal enthusiasts, researchers, and organizations to promote healthier and more resilient coastlines across Britain.

At a glance

Investigate kelp along your stretch of coastline

Type of activity: Outdoor sampling of kelp and an online survey

Who can take part? Anyone who has access to a beach with kelp on it

When? Ongoing

Where? We would love you to survey any beach or rocky shoreline that has kelp on it. If you’re unsure where to go, please email [email protected] for suggestions.

How long will it take? 45 minutes to survey, then a 10-minute online form

By engaging with nature and participating in coastal activities, you can enhance your mental well-being while contributing valuable insights into the management and protection of coastal ecosystems.

The first strand of this project was the Underwater Forests survey.

We have also developed a Coastal Health Toolkit that helps people design, deliver and improve coastal community science projects around UK shores. View the toolkit.

The Underwater Forests survey

This survey is recording kelp forests along the British coastline. Kelp forests are one of Earth's most productive habitats: they support a wide variety of marine life by providing habitat, shelter and nursery grounds for species such as seabream, bass, cuttlefish, lobsters and a wide range of marine invertebrates.

Kelp forests also alter the movement of water on the coastline and can provide a buffer against storm damage by reducing wave energy onto the land.

Taking part

Participants survey the kelp every month at a given location on the lowest tide of the month.

The survey consists of:

  1. Taking photographs of the kelp patch from a distance.
  2. Heading down to the kelp patch and completing three surveys at different points within the patch by counting kelp within a 1m x 1m quadrat.
  3. Submitting the data you collect to an online form.

You can download the instructions to print at home (PDF 23MB), or email [email protected] and we will send you a booklet.

Making a quadrat for your survey

You will also need a quadrat, a square frame used to identify a survey area for scientific study. The Underwater Forest survey uses a 1m x 1m quadrat. A quadrat can be bought online or you can make your own with bamboo or string:

  • Cut 4 x 110cm lengths of bamboo, lay out in a square so there is a 5cm overlap at each corner, and secure with tape.
  • Cut a 4m length of string and tie knots at 1m intervals, to mark the corners. Hold the corners to arrange into a square on the ground.

The Underwater Forests project is part of the UK government’s HM Treasury funded Coastal Health, Livelihoods and Environment Shared Outcomes Fund. This aims to provide a data and analytical framework to understand and monitor health status of coastal marine organisms and their ecosystems.
