Abstract

In this study, we present results of predictive habitat mapping for two rare woodpecker species – three-toed woodpecker (TTW) and white-backed woodpecker (WBW) – in the Polish Carpathians, based on recent bird surveys and the environmental data extracted from a forest inventory database. Models for both species proved useful for the identification of suitable habitats with high conservation value. The data used for preparing and testing of habitat prediction models for TTW and WBW was based on the Maxent algorithm (Phillips et al., 2006; Phillips and Dudík, 2008), which computes the predicted habitat suitability as a function of corresponding environmental variables. Based on this model we were able to predict not only the probable woodpecker locations, but also potential migration trails for studied Carpathians populations. Moreover, we tested the performance of the model for TTW while applying it to design a monitoring scheme for the species' population in Polish Carpathians. The monitoring scheme includes 130 sample plots (2 x 2 km), each plot containing at least one 25 ha habitat patch with the TTW occurrence probability (P) equal to or greater than 0,5. First inventory in 2011 revealed that 74 out of 80 in the Polish Carpathians contained breeding TTW pairs, therefore providing a good validation of the model in the field and confirming its practical applicability. Our results suggest the need for a holistic approach to forest management in order to reconcile woodpecker habitat requirements with regular forestry practices
