Autecology and ex situ growth of Leontopodium nivale subsp. nivale (Asteraceae) from North Pirin marbles (SW Bulgaria)
Kozuharova, E., Panayotov, M. & Spadaro, V.: Autecology and ex situ growth of Leontopodium nivale subsp. nivale (Asteraceae) from North Pirin marbles (SW Bulgaria). — Fl. Medit. 28: 187-206. 2018. — ISSN: 1120-4052 printed, 2240-4538 online. Leontopodium nivale subsp. nivale is a local and disjunct endemic of the central Apennines in Italy and the Pirin Mountains in Bulgaria. The aim of this study is to investigate in situ microhabitat specifics and ex situ ontogenesis regarding the possible future cultivation and to evaluate hazards for wild populations in conditions of human impact and climate change. Leontopodium nivale subsp. nivale is stenobiont which is difficult to grow ex situ and t…
Old-growth forests in Bulgaria: distribution, characteristics and conservation issues
Natural diversity of relief, climate variability, geographical as well as historical reasons contribute to the presence of old-growth forest patches in various forest types in Bulgaria. For reasons of biodiversity protection, scientific studies and forest certification several projects aimed at locating and collecting data for old-growth forests in Bulgaria. Our aim is to summarize the available findings and contribute for a general map of these forests. The sources of data combine inventory data, including fieldwork collection of forest structure data by members of our team, and verification of satellite and aerial images. Most widely distributed old-growth forests in the country are Fagus…
