Abstract

Na širšem obmocju Polhograjske Grmade je bilo narejenih 34 fitocenoloških popisov vegetacije po standardni srednjeevropski fitocenološki metodi. Doloceni so bili naslednji sintaksoni gozdne vegetacije: Genisto januensis-Pinetum sylvestris Tomažic 1940, Querco ostryetum-carpinifoliae Horvat 1938, Ostryo-Fagetum M. Wraber ex. Trinajstic 1972, Hacquetio-Fagetum Ž. Košir ex. Horvat et al. 1974, Arunco-Fagetum Ž. Košir ex. Horvat et al. 1974 in Blechno-Fagetum sylvaticae (Tüxen & Oberd. 1958) Rivas-Martinez 1962. Gozdna vegetacija na raziskovalnem obmocju je bila podrobneje opisana in kartirana. Izvedena je bila primerjava rastišcnih dejavnikov na podlagi Landoltovih fitoindikacijskih vrednosti, ki je pokazala opazen gradient pri svetlobi, kontinentalnosti, vsebnosti hranil in vlažnosti tal. Najvecji vpliv na te ekološke dejavnike imata ekspozicija in strmina, predvsem na osoncenost in tlotvorne procese. Na popisnih ploskvah je bilo popisanih 222 vrst semenk in praprotnic, štiri vrste so na Rdecem seznamu, 15 vrst pa je na seznamu zavarovanih domorodnih rastlinskih vrst. Zaradi opustitve kmetijske rabe je širši vrh Grmade v zarašcanju. Veliko sestojev je v sukcesiji, ki zaradi zaostrenih razmer poteka pocasi.

Secondary title:	Forest vegetation of Polhograjska Grmada in dependence of natural conditions and land use
Secondary abstract:	Thirty four relevés were made in the wider area of Polhograjska Grmada and the standard Central-European phytocoenological method has been applied. The following syntaxa of forest vegetation were determined: Genisto januensis-Pinetum sylvestris Tomažic 1940, Querco ostryetum-carpinifoliae Horvat 1938, Ostryo-Fagetum M. Wraber ex. Trinajstic 1972, Hacquetio-Fagetum Ž. Košir ex. Horvat et al. 1974, Arunco-Fagetum Ž. Košir ex. Horvat et al. 1974 in Blechno-Fagetum sylvaticae (Tüxen & Oberd. 1958) Rivas-Martinez 1962. Forest vegetation in the research area has been described and mapped. A comparison of site factors was made on the basis of Landolt's phytoindicatior values, which showed significant gradient of the following ecological parameters: light, continentality, nutrients and humidity. The biggest impacts on these ecological parameters are exposition and slope, especially on the sun exposure and soil forming processes. On relevés 222 taxa were recorded, four taxa are on the red list of threatened species and 15 taxa are on the protected native plant species list of Slovenia. The area around the peak of Grmada is in overgrowth because the agricultural use has been terminated. Many stands are in succession, which is progressing slowly due to harsh conditions.
