Why the brown bear is in danger of extinction

One of the problems that the brown bear has presented in recent decades is that it has a presence in Europe, Asia and North America . This, a priori, can make us think that it is a species that enjoys a good situation in the face of the possibility of its extinction, since its presence in the wild extends up to three different continents. However, the problem that must be taken into account is that, despite occupying large areas, the number of specimens in each of them is, on many occasions, less than 50 mature specimens (that is, of reproductive age) . Which foresees a complicated situation as far as its survival is concerned.

In the case of the Iberian Peninsula , today there are two population centers of brown bears that also represent almost the only ones located in the westernmost Europe, which are the Cantabrian Mountains and the Pyrenees. In addition to these two nuclei, in Europe we can also find brown bears in the region of the Balkan Peninsula and in part of the Scandinavian Peninsula, as well as in part of the Baltic States and Russia. However, with the exception of Russia, where the population areas are more extensive, the rest of the European regions are completely isolated from each other, which does not allow the different populations of brown bears to be related to each other, greatly limiting the possibility for populations to prosper.

First, the already mentioned isolated and disconnected populations make genetic exchange difficult and severely limit the possibility of reproductive success. Despite this, the threats facing this large mammal are many more, and go beyond a problem merely related to the geographic distribution of populations. These are the main causes of the danger of extinction of the brown bear :

Slow reproductive period

Keep in mind that the gestation period of bears lasts twelve months. From him, between one and three young will be born, which will remain with the mother for about a year and a half. In this way, the interval between calving would be, in the best conditions, every two years, which makes the reproduction of the brown bear slow, so that populations cannot grow rapidly in short periods of time.

Destruction of brown bear habitat

In addition to its slow reproductive process, another of the difficulties that brown bear survival presents is the destruction of its natural habitat as a result of human activity, for example indiscriminate felling of forests . The brown bear lives mainly in forests, areas that are increasingly difficult to find due to deforestation and building resulting from human activity. In fact, there are more and more cases in which bears descend from the mountains, where forested areas are still more abundant, to rural areas in search of food that they cannot find in the wild.

Human infrastructures

Another problem that occurs in some areas where the areas of presence of brown bears are more extensive than in Europe are the infrastructures that limit their ability to move. In this sense, a road or a highway can become a real impediment for the populations of brown bears to become related to each other. However, this problem can be solved with some ease, since it is enough with the construction of steps for large animals, something that is already being done in countries like Canada.

Brown bear hunt

Although it is true that it is becoming a lesser problem due to the laws that prohibit its practice in many countries and territories, the reality is that, even today, we can find different areas of the planet where hunting constitutes a real threat to animals. brown bear populations.

Currently, the most effective way to protect this animal is in the hands of governments and public administrations, as well as their ability to delimit protected areas where the habitat of the brown bear is preserved. In addition, it is also important to allocate financial resources that allow effective monitoring of the remaining brown bear populations, as well as taking the appropriate measures to guarantee their reproductive success , such as the construction of animal passages or the introduction of new ones. specimens in the most deteriorated populations.

An example that has been carried out in this line of support for brown bear populations is found in the Pyrenees population, where, in 2016, a new male brown bear was released from Slovenia. This bear, baptized as Goiat, represented the introduction of new genetic material to a particularly damaged brown bear population, where it is estimated that only about 20 individuals of mature age and with reproductive capacity remain, so the introduction of Goiat represented a new hope for this threatened brown bear population.
