The nature reserve situated between the villages of Ig and Podpeč at Ljubljana Marshes is dedicated to conserving the unique natural environment of the wetland area known as Iški Morost. The reserve is crossed by a 1.3-kilometre nature trail called Koščeva pot (Corn Crake Trail). The trail, called after a rare and endangered bird species, offers a unique insight into the wetland wildlife and animal species.
Ljubljana Marshes' biodiversity
The wetlands of Ljubljana Marshes are inhabited by as many as 89 butterfly species and are the nesting habitat of a hundred different bird species, a half of all bird species living in Slovenia. Even larger is the number of different birds spending the winter at Ljubljana Marshes or stopping over on their migration route to warmer climates.
Ljubljana Marshes provide habitat for several bird species endangered across Europe and the world, such as the corn crake (Crex crex), the Eurasian curlew (Numenius arquata), the common quail (Coturnix coturnix), the Eurasian woodcock (Scolopax rusticola), the Eurasian scops-owl (Otus scops), the whinchat (Saxicola rubetra), the grasshopper warbler (Locustella naevia), and the northern harrier (Circus cyaneus).
