Foraging Seaweeds Guide

As an Island, we are surrounded by the ocean and as such, we’re also surrounded by a vast abundance of seaweeds. We’ve put together these Foraging Seaweed Guides to help with that,

Seaweeds are a safe place to begin foraging, edible & packed full of nutrients and minerals.

These guides can be used to help you develop and are best used alongside some hands-on learning which we can help you with on one of our wild food and foraging courses.

The information provided below is made to act as a guide, when foraging for yourself you are ultimately in control of what you do and eat. Remember to only eat what you’re 100% certain of.

If there are any extra guides you’d like to see made or updated then please let us know by getting in touch here.

If you'd like to learn more why not join us on a Foraging Course

We Cover Plants, Trees, Mushrooms and Seaweeds and run throughout the UK

Use the search bar below to search for something very specific you’re looking for and it will display everything we have linked to that. For example I’m looking for information of Douglas Fir – if I type it in below I’ll get identification guides, recipes and any other posts linked to it. or Scroll down to see our Foraging Seaweed Guides.
