The lynx from original population are few, they are 8 to 10 in the Jura, 10 in the Vosges and 15 in the Alps. All lynx today are descendants from those few lynx. This could cause more or less long term problems of inbreeding.

Territorial and solitary, the lynx is a predator of medium size (between 50 and 75 cm at the withers) and a length of 80 to 110 cm without tail (15 to 25 cm).
Its weight is 20 to 25 kg for males and 17 to 20 kg for a female..
It has characteristic brushes of 3 cm above each ear.
Very leggy, which are themselves by their impressive size. The footprints on the ground are those of a cat but bigger. Its coat is reddish brown flecked with black, it takes a white grey much less spotted with black in winter.
Its senses are highly developed specially hearing and smell. His longevity is estimated at liberty to 10 to 15 years.
The female gives birth after 70 days of gestation for a range of 1 to 4 kids. They remain with their mother until 10 months. They occupy the territory mother some time before finding theirs.

The lynx is an animal very enduring but it has no resistance to the race.
It is able to sprint but only on a short distance because it has low cardiac capacity. Its stamina allows him to travel long distances of serveral tens of kilometers.
It is gereallly nocturnal and crepuscular. However, it can be active during the day during the rut, of if the place gives it condidence.
It lives rather in mountainous and forest between 400 and 2000 meters altitude. Its vital extent varies with the prey abundance. It is a great specialist in hunting medium game (deer, chamois); smaller prey are usually obtained by the females or young lynx (wild boar, hare, fox marmots and birds). The lynx is not a scavenger. Its hunting technic is the surprise, leaping on its prey.
