This research is made to estimate live stock and biotopical distribution of Cervidae family animals in northern part of Aukstaitija National park and in Zemaitija National park’s Ploksitne forest during winter seasons of 2006 – 2009. Also in Dzukija National park’s Zervynu forest and in Raseiniai County’s two forests. These animals are important part of hunting economy. They are effecting their environment simply through nourishment and the result of this relation comes back. These animals are a great part of forest’s ecosystem also they are affected by anthropological factors, such as hunt ant poach. There were made accountings of these animals according to selected tracks, these stock takings were made according to MacCain’s method. Later the results were extrapolated to show proportional amount of these animals during three year’s winter seasons and to know the results of biotopical distribution of these animals. It was estimated, that moose density in Aukstaitija National park was decreasing and in County of Raseiniai was increasing, while in Zematija and Dzukija National parks stayed stable. Red deer density in Aukstaitija, Zemaitija National parks and County of Raseiniai was increasing all the time, while in Dzukija national park stayed stable. Roe deer density fluctuated narrowly in all experimented areas except in County of Raseiniai notably increased. Biotopical distribution of Cervidae family animals in all experimented areas is further: moose mostly likes swamps...

Šio darbo tikslas buvo nustatyti elninių žvėrių tankumą 4 tirtuose miškuose, o taip pat rasti stirninų kaukolių ir ragų morfometrinius skirtumus, kurie buvo sumedžioti skirtingos medžioklėtvarkos miškuose. Tyrimai parodė, kad tauriųjų elnių ir stirnų gausumas sumažėjo profesionaliuosiuose medžioklės plotuose, tuo tarpu mėgėjiškuose medžioklės plotuose sumažėjo elnių, o stirnų priešingai- padaugėjo. Briedžių tyrimų laikotarpiu buvo labai negausu, o per paskutiniuosiuss dvejus metus tirtuose miškuose jie išnyko visiškai. Kaip bebūtų, buvo rasti patikimi statistiniai skirtumai tiek tarp tauriųjų elnių tankumų, tiek tarp stirnų tankumų tirtuose skirtingos medžioklėtvarkos miškuose. Briedžių tankumas patikimai statitiškai nesiskiria, nes visuose tirtuose miškuose jų gausumas labai nedidelis. Tiriant elninių žvėrių pasiskirtymą skirtinguose biotopuose, statistiškai patikimų skirtumų nerasta. Tačiau buvo rasti labiausiai mėgstami stirnų biotopai. Tauriųjų elnių pasiskirstymas biotopuose skirtingais metais labai įvairuoja be konkrečios tendencijos. Ištyrus kraniometrinius stirninų parametrus, paaiškėjo, kad pagal daugelį požymių šiaurės Lietuvos stirninų kaukolės ir ragų parametrai yra mažesni ir statistiškai patikimai skiriasi nuo vidurio Lietuvos stirninų. Nors ir statistiškai nepatikimai, tačiau skiriasi stirninų parametrai ir dvejuose vidurio Lietuvos skirtingos medžioklėtvarkos miškuose dėl komercnionio stirninų išmedžiojimo profesionaliuosiuose medžioklės plotuose (didžiausi...

The long study showed that the amount of red deers and roe deers decreased in professional hunting area whereas in club hunting area decreased only the amount of red deers while the amount of roe deers increased. The density of mooses felt into decline and finally during the last two years of study disappeared. Still and all there was found the significant differences in the red deer and in the roe deer densities in forests of different management. However in mentioned forests the densities of mooses were not significantly different. The significant differences of distributions of cervids in different biotopes were not found. There was found the most liked biotopes of roe deers during the non-vegetation period. Whereas red deer distribution in different biotopes has no regularity. The study of craniometric data showed that the parameter sizes of roebucks in the North Lithuania region are the smallest although not all are significantly different from parameters of craniometric data of roebucks in Middle Lithuania region. However the means of parameter show the same declining tendency. The craniometric data of roebucks in Middle Lithuania region in 2 different management hunting areas are lightly different. This difference was caused by commercial hunting in... [to full text]
