Data deficient Sternbergia colchiciflora Waldst. & Kit. (Amaryllidaceae) in Croatian flora – removing the veil of mist

Abstract

Sternbergia colchiciflora is a rare species in Croatia, estimated as data deficient (DD), and therefore every new finding represents a valuable contribution to the knowledge of its distribution, with implications for its conservation status in the future. In this paper we describe newly found localities, and provide observations on its current distribution and IUCN status, based on all known sites and population trends. So far, this taxon has been recorded only at a few localities along the Eastern Adriatic coast. Here, we report Mt Velebit and Krka National Park as new localities for S. colchiciflora, and confirm its occurrence on Mt Biokovo and on the island of Brač. The species typically occupies dry calcareous grasslands within eu-and sub-Mediterranean vegetation in different stages of vegetation succession. Sternbergia colchiciflora je u Hrvatskoj rijetka vrsta, procijenjena kao nedovoljno poznata (DD), stoga svaki novi nalaz predstavlja značajan doprinos poznavanju njezine rasprostranjenosti te može imati implikacije na očuvanje ove vrste u budućnosti. U ovom radu opisujemo nove lokalitete, te prilažemo opažanja o trenutnoj rasprostranjenosti i IUCN statusu, temeljem svih dosadašnjih poznatih nalaza i opaženog populacijskog trenda. Ova svojta je do sada bila zabilježena na svega nekoliko lokaliteta duž istočno jadranske obale. U ovom radu prilažemo dva nova lokaliteta (Velebit i NP "Krka"), te potvrđujemo njezino pojavljivanje na Biokovu i Braču. Ova vrsta tipično nastanjuje suhe, vapnenačke kamenjarske travnjake eu-i submediteranske vegetacije, u različitim stadijima vegetacijske sukcesije.

“…It flowers for a short period of time during the second half of September. It is considered a rare species in the Balkans (Šilić 1966;Stevanović et al 1991;Šilić & Šolić 1999;Vuković et al 2017;Mala & Maxhuni 2020). In Bosnia and Herzegovina, four localities have been reported so far (Šilić 1966;Bjelčić & Šilić 1971).…”

“…Although not endangered globally (Király et al 2011), its regional assessment category is endangered (Vuković et al 2017;Mala & Maxhuni 2020). It is listed as Data Deficient in Bosnia and Herzegovina (Anonymous 2014).…”

“…It is a rare species in Croatian flora growing on open dry Mediterranean grasslands. In the last 50 years, its populations were confirmed on five locations along the Croatian coast, including one from Šibenik surroundings and one from Krka National Park (Vuković et al 2017).Given the new knowledge on its distribution and habitat trends,Vuković et al (2017) re-evaluated its Data Deficient (DD) status into Endangered (EN).…”
