ǂa ǂdraft history, mapping and nature-conservancy evaluation

Abstract

A draft history of the artificial Stjuža coastal lagoon was reconstructed on the basis of old maps (1804 and 1873); and compared with the present-day situation using GIS. The current data were simplified to obtain comparable caregories (landscape units) with old maps. The following major landscape units were distinguished: lagoon, salt marshes, mainland, brackish rivers and estuaries, ditches and canals, salt-pans, embankment, villages and roads. On current map, a total of 47 habitat types according to PHYSIS typology occurring in 206 polygons, which cover an area of 41.6 ha, were identified and described. Habitats with greater nature-conservancy value cover 26.7 ha of the total research area and constitute 40% of the polygons described. 55.6% of these belong to halophilous scrubs - Sarcocornetea fruticosi (= Arthrocnemetea fruticosi) - and 25.9% to annual salt pioneer sward communities, dominated by Salicornia europaea. Mediterranean salt swamps (Juncion maritimi) are present to a small extent only. It could be concluded that the artificial Stjuža lagoon, constructed for fish farming purposes, developed in habitat diverse coastal wetland area after partial abandonment.

Secondary title: Vegetacija obalne lagune Stjuža v krajinskem parku Strunjan (Slovenija): zgodovinski oris, kartiranje in naravovarstveno ovrednotenje
Secondary abstract: Avtorja sta na osnovi starih zemljevidov (1804 in 1873) napravila rekonstrukcijo lagune Stjuža v Strunjanu in jo ob pomoči GIS (geografskega informacijskega sistema) primerjala z današnjo. Z namenom, da bi dobila s starimi zemljevidi primerljive kategorije (krajinske enote), sta poenostavila današnje podatke in določila naslednje poglavitne krajinske enote: laguno, slanišča, kopno, brakične reke in ustja, jarke in kanale, soline, nasip, vasi in ceste. Na današnjem zemljevidu sta identificirala in opisala skupaj 47 habitatnih tipov glede na tipologijo PHYSIS, ki se pojavljajo na 206 poligonih na površini 41,6 ha. Naravovarstveno pomembnejši habitati se raztezajo na 26,7 ha celotne raziskane površine in sestavljajo 40% opisanih poligonov. 55,6% od teh pripadajo slanoljubemu grmišču Sarcocornetea fruticosi (= Arthrocnemetea fruticosi) - 25,9% pa enoletnim slanim pionirskim združbam, v katerih prevladuje navadni osočnik Salicornia europaea Značilnih sredozemskih slanih močvirij (Juncion maritimi) je tu malo. Avtorja zaključujeta, da se je laguna Stjuža po delni opustitvi rabe razvila v pestre habitate obmorskih mokrišč.
