To assess the status of lynx we analysed lynx signs of presence within the range of the Italian Alps from 2005 to 2009. A total of 268 signs have been
collected, compared to 411 signs during the previous pentad. The distribution of the
confirmed signs of lynx presence is confined to three concise areas: the North-eastern
Alps of Friuli VG, the Trentino province and the Ossola valley in the Piedmont region. Occupancy modelling revealed a decrease of the lynx range by one third: The
estimated number of occupied 100 km2
cells decreased from 34 (pentad: 2000–2004)
to 21 (pentad: 2005–2009). Less than 10% of the Italian Alps are colonized. We estimated the number of lynx present in all the Italian Alps at less than 15 individuals.
Therefore, the persistence of lynx in the Italian Alps highly depends on immigration
from neighbouring countries.
