The routing method was used. All areas which the species inhabit according to literary sources were visited. Established were 12 populations of M. jankae and 32 populations of M. grisebachii. All established populations of M. jankae were from the Eastern Balkan Range on the territory of Sinite Kamani Natural Park. Three of the registered populations of M. grisebachii were from North-Eastern Bulgaria (Shumen region, near village Madara). Thirteen were from Sredna Gora Mts (nine on the territory of village Rozovets, two between village Rozovets and Bratan peak, two on peak Orlite and one between peak Orlite and the megalith Popova turla, rock formation along the road from village Rozovets to the rock formation Pravite kamani, the rock formation Pravite kamani, rock formations west of the megalith Pravite kamani, and one above village Pesnopoy in the area Usoykata). Nineteen were from the Eastern Balkan Range on the territory of Sinite Kamani Natural Park. Each population was assessed and the factors with negative influence were indicated.

The aim of the study is to establish the current Through the use of Methodology for distribution оf Moehringia jankae Griseb. Ex monitoring vascular plants in Bulgaria, we Janka and Moehringia grisebachii Janka in were able to determine the status of each Bulgaria. population. MATERIALS AND METHODS The formation in the rocks of the studied area The study was conducted during the vegetation was identified based on the Geological Map of periods of 2017 – 2018. The routing method Bulgaria scale 1:500000, Ministry of was applied to establish the distribution of the Environment and Waters National Geofund species. To determine the locations and status and Geology. of M. jankae and M. grisebachii in Bulgaria we visited and researched mainly on the territory The voucher specimens were deposited in the of: Eastern Balkan Range (Sinite Kamani herbarium of the Agricultural University in Natural Park), Sredna Gora Mts.

Rozovets – peak Bratan – village Svejen – RESULTS AND DISCUSSION village Pesnopoy); Thracian Plane (Haskovo – Moehringia jankae Simeonovgrad); Tundja Hilly Plain (village In the present study there were no discovered Matochina – village Mihalich – village populations of the species in North-Eastern Varnik); North-Eastern Bulgaria (Shumen – Bulgaria (Shumen region). village Kiylevcha – village Troica – village Madara). On the territory of Eastern Balkan Range - Sinite Kamani Natural Park were registered a A Global positioning system (GPS) was used total of 12 populations of Moehringia jankae – to determine the coordinates of the sampling 4 in Kamilata area, 3 along Haiduschka pateka points.

Two of the Haiduschka pateka area, east of Каmilata area, populations – from Karandilska polyana and north of Каmilata area, rocks between hotel Kaloyanovi kuli area have retained their area, complex Karandila and Каmilata area were while for the other seven populations is recorded described by Grozeva & al. (8) after field an increase in the area. This, according to studies during the vegetation periods 2013 – Grozeva et al. (8), is most probably due to the 2015. For the six-year period (2013-2018) they wetter spring and summer and the more abundant have increased in number while only the moisture allowed for the majority of mature population from Kaloyanovi kuli area has seeds that had fallen in rock crevices to develop experienced slight decrease in 2018 compared successfully. For the newly established three with 2015. A great increase in the numbers populations of the species from Каmilata area, was registered for the population along indicated under numbers 10 to 12 in Table 1, there were no recorded changes in the area and Haiduschka pateka area east of hotel complex numbers during the two-year period of study.
