Pyrenean brown bears: how many are there?

It is very difficult and expensive to count the members of such a discreet species living on a large steep wooded territory over the Pyrenees. It’s the reason why, apart from direct observations (animal, tracks or droppings), some indirect counting techniques have been set up. The most frequently used are:

  • Paw prints report:  any paw prints left by a bear are plaster moulded and compared to a list of paw prints reference. This can allow, in some cases, to identify an animal.
  • Photographic trapping: bears are lured with food such as meat, fish, treacle or anise in order to get in the camera field of view. This camera, which has got a sensor, starts triggering when the bear appears.
  • Hair trapping: a few devices, among them brushes, are tied to the trunk of some strategic trees. Most of the time these trunks have been coated with lure and the bear, which will rub on it, will leave a sample of hair. And as the video shows it, it works! These samples will be examined and a genetics study will allow not only to identify the animal but also to find is family tree.

Currently, there are around thirty bears in the Pyrenees.

Cantabrian brown bears: how many are there?

The Cantabrian Mountains, in the north of Spain, stretches over Castilla y Leon, Cantabria and Asturias regions. After passing through a difficult situation at the end of the 90’s, the Cantabrian bear population is slowly getting better, thanks to the work and willing of a few men and particularly to the FOP team (Brown Bear Foundation). 

“The brown bear’s genetics study in the corridor between the populations and in the western Cantabrian subpopulation”, completed in 2014, highlights that the two kernels separated from each other for more than a century (western massif and eastern massif) are again in contact and protected from the genetic drift they were suffering.

A recent estimate indicates that the Cantabrian bear population counts up to 230 animals, scattered over a surface area of 4900 km2. So, as the following video shows, it is now possible to watch them. This video has kindly been lent by our colleagues from FOP.
