During August and September 2018 we collected the macroinvertebrate fauna in the Leqinat Lake, Kosovo. The Leqinat lake (great lake) is a mountain lake found in the National Park “Bjeshkët e Nemuna” in western Kosovo, shared between Kosovo and Montenegro. Macrozoobenthos specimens were collected with D-frame net of 30×20 cm (600 cm2) diameter. Samples were taken from all available habitats represented with more than 5% of total habitat area on the sampling stretch (multi-habitat sampling procedure). Sampling in riffle section of the lake was done by identifying the riffle segments, disturbing the substratum with the feet while holding the net downstream with the mouth facing upstream. The macrozoobenthos structure during this investigation includes: 2 classes (Bivalvia and Gastropoda), 2 subclasses (Hirudinea and Oligochaeta), 6 orders (Ephemeroptera, Plecoptera, Trichoptera, Diptera, Coleoptera and Odonata), 15 families, 6 genera and 86 specimens. The larger numer of families and individuals belongs to the Odonata order (4 families and 47 specimens) followed by Tirchoptera (2 families and 10 specimens), Plecoptera (2 families and 6 specimens), Bivalvia (2 families with 5 specimens) Diptera (1 family with 12 specimens), Ephemeroptera and Hirudinea (1 family with 3 specimens) and Oligochaeta (1 family with only 1 specimens). This investigation is a contribution in knowing the macroinvertebrate fauna and their ecological patterns in alpine lakes in Kosovo.

During the spring of 2011, forty-five macrozoobenthos samples were taken from streams and rivers all over the Dragash Municipality in order to assess the impact of inhabited areas in these freshwater ecosystems, considering the fact that there is no sewage treatment and waste management is dysfunctional in many parts of this Municipality. On the basis of the habitat structure evaluation, basic physical and chemical analysis and Family Biotic Index according to Hilsenhoff and EPT Index (Ephemeroptera Plecoptera Trichoptera), this study shows that the freshwater ecosystems in the Dragash Municipality are heavily polluted and impacted by human activities in their midstream and downstream segments. The main sources that deteriorate their natural ecological conditions in these segments are: load of all kinds of waste directly into the rivers and streams, industrial discharge into the freshwater ecosystems and the direct sewage discharge into the rivers and streams all over the municipality. This study also shows that the freshwater ecosystems of the area in their upper reaches are home to very interesting and rare composition of aquatic fauna. Several species and many potential ones which live only in this area and nowhere in Kosovo or abroad, or their distribution elsewhere is very limited, have been found.

The municipal waste composition in three localities in southern Kosovo was analyzed in 2004 and 2017. The results show that most of the municipal waste is composed by biodegradable components and at a lesser degree by cardboard, glass, plastic, metals etc. The presence and increase of hazardous waste in municipal containers was observed in all investigated localities. This study showed that there was no significant change in the municipal waste composition in 2017 compared to 2004. This investigation through a case study in the Prizren Municipality is a contribution to the municipal waste management in Kosovo. It highlights the importance of including the registration of individual and organized cardboard, metal and plastic operators into the municipal waste management system, in order to know the exact amount of waste produced per capita. It also emphasizes the importance of organizing separate containers for hazardous waste due to the possible significant environmental and health problems.
