Characterizing the suitability of new ponds for amphibians Anton H.P.

Newly constructed ponds in the Netherlands were sampled for the presence of amphibians. Nine species were found. Relationships were established with pond characteristics and effects were found of fac- tors such as pond age, topography of the surroundings, vegetation cover of water and bank, and electrical conductivity of the water. A total of 16 pond characteristics were screened for their explanatory power to discern ponds that are or are not inhabited by a certain amphibian species. Also interactions between pond characteristics were screened, and were often found to be significant. For example, electrical conductivity was strongly related (negatively) with Rana temporaria presence in the older but not in the younger ponds. The greatest number of effects were found for Triturus vulgaris and the least for T. cristatus. The effects give indications as to the specific requirements to be considered when constructing ponds.
