In addition , a marshalling yard is to be constructed in the Lug Field nearby Drež nica . This is disastrous option since the Lug Field is an intact natural oasis and a habitat to many rare and endangered flora and fauna species ( not only subterranean ) . Moreover , any damage might affect the springs at the foot of Kapela ( Mountain Range ) , which are hydrologically connected with the sinkholes in Drež nič ko polje ( Field ) . These sinkholes are used as a source of drinking water for the entire Ogulin region .
Takva je opcija katastrofalna ne samo zato jer je polje Lug netaknuta oaza prirode i stanište mnogih rijetkih i ugroženih biljnih i životinjskih vrsta ( ne samo podzemnih ) , nego i stoga što bi , ukoliko dođe do havarije , mogli stradati izvori u podnožju Kapele koji su hidrološki vezani s ponorima u Drežničkom polju , a iz kojih se crpi pitka voda za čitav ogulinski kraj .
