Wet meadows are the greatest treasure of the Ljubljansko barje and the cradle of rare and endangered species. Their extent is rapidly shrinking here, just as it is elsewhere in Europe. Meadows were once intended for the production of bedding, but today for the production of fodder, which is why they are also fertilized more often. Earlier and more frequent mowing, which, on top of everything, is carried out on a large area at the same time, impoverishes the diversity of the plant world, and indirectly also affects the diversity of animal species.
On the meadows of the Ljubljansko barje, it is increasingly rare to find the bluish spikes of Purple moor-grass, mixed with colourful flowers. By losing the wealth of plant species, we are also losing the diversity of other living beings. Among other things, wet meadows are home to a buzzing multitude of insects and other invertebrates. These creatures are not only important pollinators but also serve as food for many animal species, including birds and amphibians. Furthermore, birds and amphibians themselves play a crucial role in the food web.
Apart from that, the meadows are threatened by overgrowing species brought from distant areas. With their rapid growth and impassable stands, some of them turn variegated meadows into green deserts. Such species are also called invasive alien species.
