Eurasian lynx in Spain

December 15th, 2016

A couple of interesting recent developments on the old presence of the Eurasian lynx in Spain and its hopeful reintroduction. It is thought the animal would have co-existed with the very edge of the Iberian lynxes range in northern Spain and the Pyrenees.

The possible presence well into the 20th century of the so-called gatillop in the Catalan Pyrenees as the animal is known in Catalan has long been discussed. There is now a Catalan government plan, as yet to be carried out, to release Eurasian lynxes in the Vall D’Aran in the Pyrenees. More here (2016)

Evidence now shows that the Eurasian lynx existed in Northern Spain in the Cantabrian mountains until at least 400 years ago. (2015 RTVE)

Lynx controls predators

Wolves expanding in Catalonia

April 5th, 2011

The wolf appears to have firmly returned to Catalonia after an absence of more than 70 years. In the last few years a dozen  or so animals have been gradually arriving from France (see below) and settled in the Pyrenees, and have even reached as far south as the Vallés Oriental. The news  was released in the latest issue of the Spanish wildlife journal Quercus which reports the presence of up to 13 different individuals, some identified only once and others that appear and disappear depending on the  year.  However, so far all animals have been males, except for a female detected in 2008. This  is a common pattern, as young males tend to be the first to disperse, which explains in part why so far there is no evidence of breeding in Catalonia.The wolves have been detected in across an area of some 1,400 square kilometers in the Cadi mountains and other surrounding mountain ranges in Alt Urgell, Cerdanya, Alt Solsonès, and Berguedà. Unsurprisingly, the animal’s return has revived the traditional conflict with farmers and in the early years there was an average annual loss of about 80 head of livestock, although in some years more than 200 were lost. These attacks on livestock, for which farmers are compensated, have declined dramatically following various protective measures: just 3 sheep were lost in 2009 and 10 in 2010. ABC + Photo from here

 

How long before they reach Barcelona’s Collserola I wonder.

I wrote this last year

Tests have shown that this new influx of wolves in Catalonia is genetically Italian in origin, forming part of an expansion over a number generations out from the Apennines. The Apennine population began to expand in several directions from the early 1990’s. It moved north into the Italian and Swiss Alps; north-east into the French Alps and Lyon, and east towards the Pyrenees, reaching the Maritime Alps near Nice by 1996, Saboya by 1998. An individual was detected between Areja and French Cerdenya by August 1998 in the Madres Massif, just to the north of Canigó, and finally by 2004 into the Cadí range. The last Catalan wolf was shot in Horta de Sant Joan, in Tarragona in 1929, though the animal is thought to have disappeared from the Sierra de Cadí more than 100 years ago

March news

March 29th, 2011

I’ve been woefully neglecting this section of iberianature recently. Here are a couple of recent wildlife stories in the English press.

The Missing Lynx (The Guardian) Good article. “Ten years ago, there were barely 100 Iberian lynx left. But an innovative Spanish conservation programme is rescuing them from the edge of extinction”

And this story about ancient giant bunnies from Menorca reported in The Scientist

The skeletal remains of a 26-pound rabbit was found on an island off the coast of Spain. Dubbed the Minorcan King of the Rabbits, this ancient rabbit lived approximately three to five million years ago and now adds evidence to a curious rule concerning the evolution of animals in islands. The so-called “island rule” states that big animals will get smaller and small animals (such as rabbits) will get bigger when the population is isolated on an island, perhaps due to the lack of mainland predators. In this case, the King is a whopping six-times larger than living European rabbits, but due to a rigid spine and short legs, it was also unable to hop.

Wildlife trip report to Extramadura

December 13th, 2010

otters_running

My friend Lisa has posted this excellent wildlife watching report to Extremadura. I love reports like this that don’t just focus on the birds. Lots of interesting stuff on insects, amphibians and as you can see, she chanced upon these otters at a “a small, reed-fringed reservoir” somewhere near Torrejon el Rubio. “Gambolling along the spit they chased away a competing Little egret before returning to the water and swimming towards the main body of the reservoir, followed by a very excited otter-watcher.”   Read more here
