Eurasian collared dove

Collared doves (Streptopelia decaocto) bred in Britain for the first time in 1955, in Norfolk. Within 20 years they had colonised every county in the British Isles, and had even reached Shetland and the Outer Hebrides.

More about Invasive Species Week

Invasive non-native species are one of the top five causes of biodiversity loss worldwide. Here in the UK they harm the environment, threaten some of our rarest species and cost our economy over £1.8 billion a year.

Invasion of the Spanish squill

On Friday we posted a gallery of grey squirrels, an invasive alien species that has almost completely replaced our native squirrel population. Unfortunately, our native bluebell (Hyacinthoides non-scripta) is also being threatened by the spread of an invasive alien: Spanish squill (Hyacinthoides hispanica), a similar bluebell species imported into our gardens from southern Europe during the 17th and 18th centuries.

Lesser Celandine

The lesser celandines (Ficaria verna) are in flower. Celandines are the floral equivalent of the swallow, they appear around the same time and mark the coming of spring. In fact the word celandine comes from the Greek name for swallow: chelidon. One of its local names is spring messenger; others are brighteye, butter and cheese, frog’s foot, golden guineas and, less romantically, pilewort because it was once used to treat haemorrhoids.

The Battle of The Spanish Squill

By Ian Bushell

For the last couple of Sundays, I have been looking for Spanish squill among the bluebells. I have gone early and used the allotment entrance to the park.

Grey squirrel invaders

The park’s grey squirrels are invasive aliens, brought here during the 19th Century, when the possession of rare and exotic species of plants and animals was the height of fashion. Grey squirrels, native to eastern North America, were first released into the wild in Britain, at Henbury Park, in Cheshire, in 1876.

Hogweed

This has been a year of astonishing growth: more grass than we have ever seen, nettles at head height, trees and shrubs sagging under the weight of blossom. Our common hogweed (Heracleum sphondylium) is standing seven feet tall in places with flower-heads the size of dinner plates.

Giant swarms of cannibalistic Harlequin ladybirds riddled with an STI are invading British homes: this is a headline in the Mail Online this week. No wonder our relationship with our environment is deteriorating when the country’s most-read news outlet uses such inflammatory language to describe a natural phenomenon. Swarm, cannibalistic, riddled, sexually transmitted infection, invade: could they have squeezed any more knee-jerk melodrama into a single sentence?

A red squirrel?

We received this, by email, from Simon Handley:

Dear FOSCP,

My good lady is convinced that she saw a red squirrel in the park the other day. I saw it too (a fleeting glimpse) and at first I thought it was a chipmunk (??!!) and then thought it seemed a lot redder than grey. Is this possible? It was along the path along the stream between Lambrok Meadow and the large pond. Be grateful for your thoughts. 

Kind regards 

Simon & Sarah Handley
