西ドローニングモードランドにあるスウェーデンの3つの基地(ヴェストフェラのワサ基地と野外基地, ハイムフロントフェラのスベア野外基地)は人為的な環境変化に影響を受けやすい蘚苔・地衣類が豊富に生育している地域に設置されている。基地活動による環境評価のプロジェクトの一環として, 蘚苔・地衣類を用いた長期的モニタリングが計画された。120の永久方形区からなる11のライントランセクトが3つの基地に設置された。トランセクト上と方形区内の植物が記載され, 記録方法が示された。方形区内で記録された種は将来の比較を容易にするように考慮され, その地域に代表して出現する地衣類だけを記録した。ハイムフロントフェラでは1293地点で18種の地衣類が記録され, ベストフェラでは704調査点で13種が記録された。 Results from a biological investigation reveal that all three Swedish Antarctic Stations in western Dronning Maud Land (i. e. the main station Wasa at Basen in Vestfjella, a small field station at Fossilryggen in Vestfjella, and the field station Svea at Haldorsentoppen in Heimefrontfjella) are located in areas having a rich and vulnerable lichen and moss vegetation. As part of a project to monitor local human environmental impacts associated with activities at the Swedish stations, a long-term monitoring study using lichens and mosses was designed. Eleven transects consisting of 120 permanent plots (and 3000 subplots) were established at different distances from the three stations. The transects and plots are described and the principles used in recording them are given. All records made within the plots are presented to facilitate future comparisons. The transects were not intended to be representative for all habitats at the nunataks. The species recorded in the plots thus represent only a selection of the lichens present within the study area. Eighteen lichen species were recorded within the plots in Heimefrontfjella from a total of 1293 observations, and in Vestfjella thirteen species were recorded from a total of 704 observations.
