Digging up peat to sell as garden compost is bad for bumblebees, it releases centuries of stored COβ‚‚ and destroys habitats – and more than 16,700 people have shown they care. Time for the Government to deliver on its promise and #endpeatsales, once and for all.

Congratulations to @victoriamallinson.bsky.social for winning The Olivia Norfolk Prize for her research on the impact of spring cold snaps on bumblebee colonies.

In 2026, Victoria, a Trust-supported PhD student, hopes to examine the impact of real cold snaps using the BeeWalk dataset.

β€˜I rarely get outside’: scientists ditch fieldwork in the age of AI Nature - In the race to embrace new technologies, some ecologists fear their field is losing touch with nature.

Can you identify UK bumblebees and/or butterflies to a species level in the field?

Or do you have strong botanical survey skills (equivalent to FISC Level 4 or higher) with the ability to recognise broad and priority habitats?

See great opportunity below & please share!

Trump officials set to approve β€˜forever chemical’ as pesticide ingredient Critics say that fifth Pfas Trump’s EPA has proposed for approval this year would put food and water supply at risk

During his campaign, Trump (& RFK) promised to rein in the use of dangerous pesticides, but the EPA has loosened oversight and is accelerating pesticide approvals.

Notably, the top 4 positions in the new Trump EPA’s chemical safety office are held by former pesticide and chemical industry lobbyists
