IPA ManMon Project - Monitoring of Dalmatian Scilla (Chouardia litardierei (Breistr.) Speta) in Croatia

Dalmatian Scilla or Amethyst Meadow Squill (Chouardia litardierei (Breistr.) Speta, syn. Scilla litardierei Breistr.) is an endemic Illyrian species and one of 20 Croatian Natura-plant species of interest to European union. It inhabits wet grasslands of many periodically flooded Croatian karst fields of the mainland, coastline and northern-Adriatic islands. Main vegetation that dominates these habitats belong to the Order Trifolio-Hordeetalia Horvatić 1963 (Molinio-Arrhenatheretea Tx. 1937), and less the Orders Molinio-Arrhenatheretea Tx. 1937 and Agrostidetalia stoloniferae Oberd. 1967. In the mainland, Scilla grows mostly in the As. Molinio-Lathyretum pannonici Horvatić 1963 and As. Scillo litarderei-Deschampsietum mediae ("Deschamsietum mediae illyricum (Zeidler) Horvatić 1963"), and less in the Alliance Caricion davallianae Klika 1934. In the coastal part (islands), Scilla grows in As. Peucedano-Molinietum litoralis Horvatić 1934 and As. Trifolio-Hordeetum secalini Horvatić (1934) 1958. According to the schemes of the Croatian State Institute for Nature Conservation (SINP), a representative number of Scilla-habitats were put under a standardized monitoring-procedure during two-year range. In 2013, we conducted a monitoring procedure alongside vegetation investigations, in Plitvička jezera National Park and Velebit Nature Park, than in the Gacko, Plaško and Ličko karst fields. In 2014 we expanded the investigations to Imotsko, Mućko, Vrličko, Cetinsko, Paško, Lapačko and Krbavsko karst fields in the mainland, as well as to Vlašićko, Povljansko and Kolansko karst fields on the island of Pag. Dalmatian Scilla is still fairly abundant in most of the investigated sites of 20 investigated karst fields in total, being under threat mostly because of the lack of traditional human activities (abandonment of agricultural fields, regular pasturing and mowing). Following the Permissions of Croatian Ministry of environment and nature protection, we collected an acceptable number of seeds from several Dalmatian Scilla habitats, to be preserved in the Botanical Garden seed bank. We also performed a series of standardized procedures to establish a rate of Dalmatian Scilla seed germination at various temperature and light regimes.
