Much talk all the time of freshwater wetlands being great filters & cleaning water. We must remember that sending dirty water into wetlands destroys them. There is nothing more certain in science than that. Make wetlands clean!!! @ramsar.org @freshwaterbio.bsky.social

How do you get a 120% increase in wetland plants in the farmed landscape & massively increase water beetle diversity too? The answer is restore farm ponds by scrub & sediment removal - key is to go in hard & make a big impact. See new paper: share.google/VVowsJzqHdPT...

Cley-Salthouse marshes. A land full of birds & birdwatchers. But this area is so important for European eel which is critically endangered & declining in North Norfolk. Let's focus on eels too please. Eels are more than just bittern food!

A dry resurrected ghost pingo at Watering Farm, next to Thompson Common. Home to 50+ different wetland plants including water-dropwort & Various-leaved pondweed. But would rather see them with water. Especially for the fish & amphibians!

Cathedral like hedges. Not cut for many a year. As thick as guts & heaving with pollinators & insects of all kinds enclosing a valuable meadow. Hedge management is good when you don't need to manage!

Is there an old country name for the blackberries that ripen first at the start of the season at the end of the floricane? @bramblebotanist.bsky.social

Incredible structurally complex butterfly habitat at Sayers Old Meadow. 100s of Common Blues, & good numbers of Small Copper as well as Brown Argus. All on land that was arable 18 years ago. Natural regeneration. Some ground mowed annually & some left to develop naturally. No seeds introduced.

Deep clear mysterious waters of a restored farm pond. Deep down there are stoneworts & endless invertebrates that lift populations of bats & birds. All in the middle of an arable field.

A week surveying satellite lakes in the Upper Lough Erne system, Ireland. The best shallow lakes left in Europe but hugely under threat from eutrophication. Like going back 100 years in the Norfolk & Suffolk Broads. It is easier to stop lakes from degrading than to restore completely degraded lakes

A great day out with Norfolk Flora Group at a Norfolk Ponds Project restored pond landscape. Wonderful people who eat cakes & then find rare things. They then assess the quality of pubs. Very important work @ians4ad.bsky.social @jo-the-botanist.bsky.social @bramblebotanist.bsky.social

A lense of freshwater out in the fields. Restored by Norfolk Ponds Project in 2015. Managed again in winter 2024. FULL of aquatic species & as the summer draws on this will be the waterhole which keeps every critter alive. Ponds are the most important farmland habitat. Not to be ignored...
