From a relatively numerous and exceptionally qualitative wolf population, consisting in

vigorous, healthy and wild specimens that have allowed Romania to break their own world record concerning “wolf fur” in 1997, the country runs the risk, due to such exaggerated protection, to end up with a numerically reduced population, but at the same time, one that is more detrimental for animal breeders and hunters and obviously, qualitatively spoiled, with smaller, diseased, scavenger and, according to the latest data, impure specimens due to mating with wild dogs.

The evolution of the wolf population

in Romania, for the past 66 years,

represents a classic example of

exaggerated protection, a complete

lack of professionalism and

pragmatism, in an attempt to

preserve overpopulations of large

carnivores, taking into consideration

the more artificialized habitat which

is currently becoming less favorable

for most of the hunting species.

Introduction

• The wolf habitat in Romania mainly overlaps with the afforested sites in the country in the high hills and mountain area, with a relatively reduced human density.

• Apart from this relatively continuous habitat, that extends on both sides of the Carpathian Mountains, the wolf may also be found in the Apuseni Mountains and, rarely, in Dobrogea and the Romanian Plain.

• It thus creates a habitat of around 100,000 km2 (10,000,000 ha), meaning almost half of the hunting surface of the country.

Dynamics of wolf numbers, graphically highlighted based on the statistical data gathered since 1950 and up to present times, has the following explanations: • during 1950 – 1970, wolf numbers have deliberately been diminished by shooting, entrapping and poisoning, in order to reduce the damage done to animal breeders and to enable the increase in the numbers of hunting prey species (mainly deer, buck, chamois and boar); • a 20-year period followed, between 1970 and 1990, when the wolf population was maintained, by using the same hunting means and methods, at the relatively constant level of around 2,000 specimens, in a consistently followed balance, with the populations of the hunting prey species; • for the period of over 20 years that followed, after putting the wolf under strict protection, its numbers started growing dramatically as a consequence of law restrictions and the drastic reduction of yielding quotas, up to 4,000 specimens, and after 2005, it decreased relatively abruptly to a level of around 2,000 specimens, due to the decrease in the numbers of hunting prey species (deer, buck, chamois). • one may also note that, along with the decrease in yield quotas, the natural growth of the wolf population also diminished, an absolutely normal action following the population self-regulation determined by the more difficult access of wolves to specific fare.

and natural wolf growth rates

•Within a period of 20 to 25 years, estimated between

1965 and 1991, when the wolf population was maintained

at a relatively constant level of around 2,000 specimens, a

level deemed to be in balance with the numbers of prey

populations, around 1,500 wolves have been annually

extracted;

•The wolf specimens in the reference period were

vigorous, healthy, wild and less damaging than they are

now for animal breeders, as a consequence of the

presence of abundant specific fare in the natural

environment; we may notice that this was the period when

the two world records for of Romania, for “wolf fur”, as

well as the national record for “wolf skull” were achieved;

•After 1990 and after the wolf went under strict

protection, the wolf population began to abruptly increase

to over 4,000 specimens (in 2004), and later on, to

steadily decrease due to the pressure exercised, including

by the wolf, on hunting prey populations (mainly deer,

buck, chamois and boar);

•The mechanisms of population self-regulation, in the

case of the wolf in our country, could not however prevent

the qualitative degradation of the population and the wolf

becoming less damaging to animal breeders and hunters;

•We notice lately more and more specimens of scavenger

wolves and, according to the latest data, impure

specimens due to mating with the domesticated dog;

One may also notice the increase in adversity of the rural

population, particularly animal breeders, towards the

wolf.

Conclusion

• Out of too much protection, the preservation of wolf populations, normal from a numeric point of view,

vigorous, healthy and wild, is endangered due to the increase in the damages done to animal breeders and hunters, which only increases the adversity of such social strata towards the species itself.

• Considering the aforementioned, the natural question arises about when we did operate a performing management for hunters and more favorable for the wolf species:

• during 1965 – 1990, when, for a number of around 2,000 wolves, approximately 1,500 wolves/year were annually extracted, or

• in the present, when, after diminishing the yield figures to around 300 – 350 wolves/year, the population self-regulation mechanism was triggered at approximately the same population level (of around 2,000 specimens) and not even a problematic or degenerate specimen is being shot?

• The future of the wolf population in Romania depends on the answer to this question, and not only on that!
