Ornithological information An important area for raptors and forest birds.
Site description A range of low mountains situated between the Danube bend and Ipoly river.

Management considerations The abandonment of pasture management may lead to scrub encroachment, with a consequent loss of feeding areas for raptors (the nest sites of which are protected). Intensified forest management causes problems of changing age structure and disturbance to birds. Large-scale tourism results in disturbance to birds and habitat degradation, and necessitates road construction.
