The status of the Italian autochtonous batrachofauna has been analysed taking into consideration a set of 13 variables, ranging
from natural history traits (e.g. type of reproduction, number of eggs, frequented habitat), to distribution and areal fragmentation,
taxonomic uniqueness and insularity. Each variable was categorized into four ranks (0±3) of increasing risk for survival. Urodeles
and anurans were treated separately for both univariate and multivariate analyses. The results con®rm a general sensitivity of
urodeles, although in many cases newts and salamanders may react more promptly to habitat alteration and human disturbance.
On the other hand, the anurans, except for three species that are widely distributed and largely euryecious (Bufo bufo, Rana tem-
