Experts call for restrictions on pet flea treatments that harm UK songbirds Chemicals known to affect brains of common garden birds, and to kill unborn chicks, found in most feather samples Conservationists have called for restrictions on pet flea treatments after research found songbird feathers widely contaminated with substances that can damage the birds’ brains and kill unborn chicks. Almost every feather sample tested from five common species of UK garden birds contained either permethrin, imidacloprid or fipronil – all insecticides that are banned for agricultural use but still common in pet tick and flea treatments.

Stowaway raccoon put down after arriving at Southampton port A stowaway raccoon that managed to board a cargo ship which arrived in Southampton has been put down.

Bad news for the Raccoon, but this is a good example of the efficiency of the APHA rapid removal process for animals on the 'Species Alerts' list, to prevent those forming the greatest ecological/economic threats from getting established.

Massive devastation following the Israeli strikes across Lebanon.

Homes destroyed. Communities shattered. Many lives lost.

This Monks Wood #rewilding (natural colonisation) plot is 30 years old this year. It's taken that long for this single Bluebell to migrate 20m from adjacent ancient woodland to colonise the plot. But now it's here, joining the growing trees & shrubs: future ancient woodland in the making.
