Vascular plant species diversity was studied in relation to landscape variables and to threat (Slovenian red-listed species). Our results show that fragment size does not affect plant species diversity. In addition, fragment shape index is not related to Alpha diversity. Higher Alpha diversity was observed for abandoned grassland fragments. The lowest Alpha diversity was perceived on more mesic fragments, where habitat specialists are much scarcer. It was confirmed that the highest diversity of specialists are in the driest fragments, both still mowed and abandoned. With an increase in the number of distinctly different bordering habitat types, the total number of species per fragment generally does not increase, except in the case of those fragments that are already in different succession ...

For Slovenia and the neighboring regions, this species was already mentioned by Fleischmann (1844), Marchesetti (1896) and Pospichal (1897). Since the species discovery in the 20 century (1975 by prof. T. Wraber), this orchid species was observed on few locations in Istria and Vipavska dolina. Two new localities are presented, the fi rst near the settlement of Sv. Anton in Istria on fl ysch, and the second in the continental, NE Slovenia in the Goričko region okovci). According to the available data, the locality in Goričko is the northernmost point in the species distribution range. The Goričko area has the lowest precipitation rate in Slovenia with hot summers. Bedrock consists mainly
sand
and sandstone. The following thermophilous plant species were already recorded for Goričko: Verbascum phoeniceum, Muscari comosum, Petrorhagia prolifera, Papaver argemone, Rosa galica, Geranium purpureum.
Anacamptis papilionacea, typical Mediterranean species that seem to be spreading northward, into continental areas
due to change of different gradients (climate etc.). Suitable microclimate and dry, sandy substratum together with
th the climate changes may have pushed the species far into continental Slovenia. In Slovenia the species remains rare; the orchid is present with only a few plants per each locality and usually growing in the vicinity of Green winged orchid specimens (Anacamptis morio) which enable hybridization of two species.
