Lipovo polje is a karstic field in Lika region (Croatia), located north of the village of Gornji Kosinj and accumulation “Kruščica” on Lika River. It is situated at the mean elevation of 485 m a.s.l., covering area of almost 1500 ha with Lika river flowing through it. Currently, there is no available floristic and habitat data for Lipovo polje, according to the Flora Croatica Database. The field work was carried out during one vegetation season in 2012, with 67 sampled localities. A total number of 189 taxa have been identified belonging to 56 families, with Poaceae, Asteraceae and Cyperaceae having the highest number of recorded taxa. Alongside the floristic research, a habitat map of Lipovo polje (in scale 1:5.000) has been created containing 19 habitat types classified according to the National Habitat Classification. The most dominant habitats are mesophilous grasslands, cultivated fields and oak woodlands. High floristic and habitat diversity of Lipovo polje could be attributed to the variations in microtopography and land use features present in the research area. The presented results represent the data from only one year study and therefore a more detailed survey is needed for mapping the complete floristic and habitat diversity.
