The balkan endemics Moehringia Jankae Griseb. ex Janka and Moehringia Grisebachii Janka in Sinite Kamani Natural Park, Bulgaria

The aim of the study is to establish the current distribution оf Moehringia jankae Griseb. ex Janka and Moehringia grisebachii Janka in Sinite Kamani Natural Park and to assess the state of its populations. Nine populations of M. jankae and fourteen populations of M. grisebachii were registered. It has been established that the Balkan endemic M. jankae inhabits quartz porphyry rock formations, conglomerates and limestones in Karandila, Haidushka pateka, Kaloyanovi kuli, Kamilata areas at an altitude of 590 to 972 m. Its populations number from 10 to 72 specimens at an area of 0.5 to 796 m 2 . The Balkan endemic M. grisebachii inhabits quartz porphyry rock formations and conglomerates in Haidushka pateka, Mollova kuria, Kaloyanovi kuli, Karandila, Gornaka, Karakyutyuk, Kamilata and Golyama Chatalka at an altitude from 641 to 1049 m. Its populations number from 11 to about 347 specimens on an area of 1.7 to 1720 m 2 . Main threats to the populations of both species in the Natural Park are anthropogenic impact and adverse weather conditions during fruiting.
