Description

Velika raznovrstnost rastlinstva na Krasu je predpogoj za veliko raznovrstnost živalstva, predvsem žuželk. Vzroke za oboje pa lahko iščemo
(1) v apnenčasti kamninski podlagi in tanki prsti nad njo, ki otežujeta intenzivno kmetijstvo,
(2) razmeroma toplem submediteranskem podnebju, ki omogoča preživetje toploljubnim vrstam,
(3) močni burji, ki zavira zaraščanje z gozdom vsaj na vršnih grebenih in morda tudi
(4) občasnim požarom, ki v sušnih letih vračajo rastje v zgodnejše stopnje zaraščanja.
