Effects of wetland restoration on the amphibian community in the Narew River Valley (Northeast Poland). pp. 50-58.
Abstract. Habitat restoration is a mitigation tool often proposed in conservation biology, however, our knowledge about its effectiveness is still limited. Here we evaluate the effects of a large-scale drainage and habitat restoration project on the amphibian community in the Narew River Valley, Poland. We used visual encounter surveys, manual calling surveys, and dip-netting to record species presence/absence and breeding status. Data were then compared with a previous study that was conducted during the restoration process. We found a general increase in breeding activity and three species were found for the first time in the study area. Amphibians bred most frequently in ephemeral ponds on wetland meadows. Anthropogenic water bodies contained a similar number of species as natural sites did. Our results suggest that the increase in the amount of water in the river valley has had a positive effect on the local amphibian community.
Key words. Amphibia, wetland, habitat restoration, breeding success.
