We already have the final results of the habitat quality assessment for amphibians! First we identified 75 water bodies (i.e. suitable habitats for frogs, toads and newts) in the gravel pit and its surroundings. Then, we characterized 27 attributes in each water body, grouped by categories: (1) physical features (slope, maximum depth…), (2) hydrological features (regime, stream speed…), (3) water quality (pH, nitrate…), (4) vegetation (shadow, floating vegetation…), (5) surroundings (refugees, percentage of forest…), and (6) relationships with other animals (red crayfish, fishes…)..
We assessed these attributes depending on amphibians’ preferences according to specific literature, and finally we represented these results in maps of habitat suitability for each amphibian species (Pelophylax perezi, Pelobates cultripes, Pelodytes punctatus and Triturus marmoratus). The natterjack toad (Epidalea calamita) is not included in this analysis, because it breeds in any ephemeral puddle, that change in every rain event, so it would be inaccurate to define suitable water bodies for this specie.
