National Marine Week

National Marine Week

25th July - 9th August 2020

Cornwall Wildlife Trust

Dive in

National Marine Week is The Wildlife Trusts’ nationwide celebration of all things marine. Despite the name, it lasts 15 fun-filled days to allow for the variation in tide times around the country. This year is slightly different, due to the Covid-19 crisis, but there's still lots to get stuck into it! Dive in...

Report your sightings!

Want to be a citizen scientist? You can report your shoreline sightings to us!

We're particularly interested in sightings of Pacific oyster, wireweed, slipper limpet, Chinese mitten crab, oarweed, snakelocks anemone, stalked jellyfish, shore crab, beadlet anemone and common limpet, but feel free to report any other sightings as well.

Take a look

Be a champion for our seas!

Our seas need YOUR help! We're telling the Government that we need Highly Protected Marine Areas as soon as possible. These special areas would ban all damaging activities and give the wildlife there a chance to recover and thrive. 

Will you sign our letter? 

Try one of our awesome events!

Some of these events will take place face-to-face, in accordance with current Government guidance and ensuring social distancing is in place at all times, whereas other events will take place digitally, or will be self-led by participants. Take a look below!

From kayaking in Alderney, to meeting the dolphins of Wales, there's so much to explore!
