Ecological indicator values for Austrian vascular plants. Ecological indicator values of plants serve as indirect indicators for the status of ecological parameters in absence of physico-chemical measurements at place. Ellenberg introduced seven parameters which are namely light (L), temperature (T), continentality (K), moisture (F), reaction (R),...

The archaeological site of Aguntum is located near Lienz in East Tyrol. Around ten years ago, Aguntum was not attractive to visitors, had an inconsistent appearance, and no clear policy for future development. In 2014, this led to the initiation of a broad-based process to define a mission statement for Aguntum. The goal was to create a common, hom...

The presentation of the historical and recent distribution of Myricaria germanica in Austria is based upon an evaluation of historic and current literature, floristic databases and public herbaria complemented by authors’ surveys. The illustration follows the grid of the Austrian floristic mapping. The distribution map underlines historically frequ...

Floristic records of 320 interesting vascular plants are reported for Austria including the following taxa as new for the stated Austrian provinces (* new for Austria): Vienna: Allium christophii, Cynoglossum hungaricum; Lower Austria: Broussonetia papyrifera, Rhodotypos scandens*, Taraxacum panalpinum; Upper Austria: Bolboschoenus yagara, Epipacti...

In 2008, three new species of Insecta have reached the federal territory of Salzburg, Austria, which are regarded to be Neozoa. These are Andricus quercuscalicis (Burgsdorff, 1783) (Hymenoptera, Cynipidae), Stictocephala bisonia Kopp & Yonke, 1977 (Hemiptera, Membracidae) and Phyllonorycter issikii (Kumata, 1963) (Lepidoptera, Gracillariidae). Wher...

Endemic species are not a uniform group in terms of range size, habitat preferences, and ecological plasticity. Based on a recent inventory of endemic vascular plant species in Austria, we analysed distribution patterns, altitudinal distribution and habitat preferences of endemic species and analysed the correlation of range size and niche breadth....

In the City of Salzburg, Austria, 8,837 sites off neophytic vascular plants were documented by means of grid mapping between 2002 and 2008. In addition, literature and regional herbaria were analysed, thus presenting a monographic work about the alien plant flora of the region for the first time. Altogether 706 taxa were reported, including 597 fou...

During the gridmapping project of alien plant species in the city of Salzburg distribution samples of rare or not consistent non alien plants were made. From 14 of these Taxa {Amaranthus blitum subsp. blitum, Artemisia absinthium, Ballota nigra, Cannabis sativa, Cornus mas, Digitarla sanguinalis, Dipsacus fullonum, Erucastrum gallicum, Herniaria gl...

In the landscape immediately north of mount Untersberg, in the Federal Province of Salzburg (Austria), there were once extensive areas of litter meadows and moorland, of which today only small remnants are left. The biocoenoses of plants and animals of these litter meadows, which also contain a great number of endangered species, are optimally adap...

Im Jahre 2002 wurde mit einer Rasterkartierung der Adventivpflanzen in der Stadt Salzburg begonnen. Als erstes Ergebnis werden Verbreitungskarten von Cotoneaster divaricatus, Geranium purpureum, Iberis umbellata und Impatiens glandulifera gebracht. Bisher konnten rund 500 Adventivtaxa im Stadtgebiet von Salzburg nachgewiesen werden, wobei sich beso...

Von 26 Gefäßpflanzentaxa werden aktuelle Funde aus dem Bundesland Salzburg mitgeteilt. Dabei zeigt sich einmal mehr, dass trotz der regen botanischen Aktivitäten in jüngster Vergangenheit, die u. a. anhand zahlreicher Publikationen dokumen-tiert werden, noch immer beachtliche Pflanzennachweise in diesem Bundesland möglich sind und eine Weiterführun...

New floristic records of 300 taxa of vascular plants are listed concerning the provinces of Salzburg and Upper Austria and for 11 species new distribution grid maps are given. All records are discussed with literature and data of distribution, status, endangering and frequency are added. Callitriche platycarpa, Corylus maxima ,J?urpurea", Crocus to...

Records of remarkable vascular plant species in the Mollner Kalkvoralpen, the middle Steyr valley and upper Krems valley (Upper Austria) New records of 58 rare vascular plant species of the upper Krems valley, the middle Steyr valley and the adjacent Upper Austrian limestone Alps are presented. The majority of the records was made during biotope ma...

Erica tetralix L. and Lycopus europaeus L. ssp. mollis (KERNER) SKALICKY from the Kreuzerbauernmoor (Upper Austria). Erica tetralix, so far not published to the flora of Upper Austria, and Lycopus europaeus ssp. mollis were found in a fen in the district of Vöcklabruck. Besides of some other floristic data concerning this fen, remarks on the distri...

A b s t r a c t : In the year 2002, the official biotop-mapping was carried out in the municipality of Vorderstoder (district of Kirchdorf, Upper Austria). In the course of this project, several fioristic findings were made. Amongst them, Cotoneaster divaricatus, Dryopleris qffinis ssp. borreri var. robusta, Dryopteris qffinis ssp. cambrensis. Phlo...
