Abstract

Slivniško jezero je nastalo zaradi primarne funkcije zadrževanja vode in s tem zagotovilo varovanje okoliških krajev proti poplavam. Skozi leta se je ta funkcija začela spreminjati in kot primarne so prevladovale druge. Jezero je bogato naseljeno z ribami, raki, školjkami in tudi v okolici najdemo veliko živih organizmov, kot so ptice in zelo bujno in visoko rastlinje. Kot mnoge druge vode je tudi Slivniško jezero ogroženo oziroma so ogroženi organizmi, ki živijo tam. V diplomski nalogi smo se osredotočili na onesnaževanje in zastrupitev živali, ki se je zgodila v jezeru. Zastrupitev je bila ena sama, vendar ta zelo huda. Ob zastrupitvi je bil prizadet ribnik, kjer se ribe gojijo, ter potok, ki se izliva v jezero, zato je bila izguba še toliko hujša. Zastrupitev je bila namerna in storilec nikoli ni bil in tudi najbrž ne bo znan. Sanacija je potekala dolgo, ribiška družina je poslala veliko prošenj za pomoč, nekatere so bile odobrene, veliko je bilo zavrnjenih. Drugi problem okolice jezera so žabe, vendar je ta problem vedno bolj ozaveščen, ljudje so z njim seznanjeni in tudi veliko pomagajo. Problem so finančna sredstva. Cesta ob jezeru je zelo prometna, žabe pa je prečkajo na poti od svojih zimskih prebivališč do jezera. Zato so se domislili dobre rešitve, vendar vse temelji na prostovoljstvu. Vsakoletno se zbirajo in postavljajo ograje ob cesti, da bi rešili kakšno žabje življenje. Poleg ograje so pod zemljo speljani kanali, kjer lahko žabe nemoteno potujejo do jezera. Kljub vsemu trudu in postavitvami ograj, še vedno veliko žab konča svoje življenje na cesti. Lahko bi postavili daljše ograje ob cesti in še več podzemnih tunelov, saj so zdaj bolj redki. Ograjo bi bilo potrebno pregledovati dnevno, saj se pogosto trga in imajo žabe potem prosto pot na cesto.

Secondary title:	ENVIRONMENTAL ISSUES OF SLIVNICA LAKE
Secondary abstract:	The main purpose of damming Lake Slivnica was to maintain the water and thus protect the local area from flooding. Eventually the primary function of protecting the area has been replaced by some others. Today the lake is full of fish, crabs, shells and also other numerous living organisms such as birds and lush vegetation that is found in the nearby. Like elsewhere, also living organisms here are endangered, so in our thesis we focused on poisoning the lake. Even though it happened only once, the consequences were very serious. Tremendous poisoning affected the pond which fish are raised in, including the smaller stream pouring into the lake. Poisoning was intentional and the delinquent will probably never be found. Lake rehabilitation lasted for a long time, the Fishing family Voglajna involved itself a lot in sending requests for help, but were rejected many times. Another big problem concerning the surroundings of the lake, that people are much more aware of are the frogs. The frogs are endangered due to heavy traffic on the regional road, but have to cross it on the way from their living places to the lake. Since everything is connected to financial means, some volunteers came up with some other idea. To prevent frogs from dying they gather yearly in order to put up some fences by the road. Besides all there are also some canals under the road that are enable the frogs to reach their aim. Despite the effort, lots of frogs still end up their lives on the road. The solution of this problem could be placing in longer fences along the road and more canals under the road. Also these fences should be checked daily because of possibility tearing apart.
