    Opis:
    Ecotourism is widely accepted as the most effective type of sustainable development. For monitoring ecotourism sustainability in the Northern forest of Iran, a study was designed to help identifying criteria and indicators (C&I) with the principle goal to ensure the objectives of forest management, and at the same time – maintain processes in a sustainable manner. Indicators act as an instrument which can be used for monitoring sustainability. Hence indicators should be multidisciplinary, and cover all aspect of social, ecological, cultural, economic and institutional factors affecting sustainability of ecotourism. In this study, C&I were identified by using the Delphi approach through multidisciplinary panel team. Three rounds of meetings were held for discussions and dissemination of research to a panel of local experts. At the end of the second round we reached a consensus on 9 criteria and 61 indicators, which include 21 indicators related to ecological aspects, 8 to economic aspects, 21 to social aspects, 6 to cultural aspects and 5 to institutional aspects. The selected indicators would be applied by the Iranian Cultural, Heritage, Handicrafts and Tourism Organization for monitoring ecotourism sustainability in the Northern forest of Iran.

    Opis:
    Red osier dogwood Cornus sericea L. is a species native to North America, but spreading in Europe. It has been classified a kenophyte in Poland and is considered invasive. However, knowledge on its distribution is insufficient and lacking entirely for many parts of the country. Therefore, the aims of this study were to document stands of C. sericea in the buffer zone of the Skarpa Ursynowska nature reserve in Warsaw, to provide new information on morphological features that were inconsistently reported in the literature, and to summarise the known distribution of this species in the mazovian voivodeship. Field studies were carried out in 2021 within six new stands of C. sericea located in the buffer zone of Skarpa Ursynowska. The work included phytosociological relevés and measurement of the following parameters: length of leaves (blade and petiole) and the maximum height of plants. Based on the herb layer species found in the phytosociological relevés, ecological indicator values were calculated in order to determine habitat conditions. The distribution of the species in the mazovian voivodeship was then mapped by means of the ATPOL cartogram method. In the vicinity of the Skarpa Ursynowska, C. sericea occurred in scrub communities and at the early successional stages of forest development that is in habitats with favourable light conditions, sufficient humidity and fertility. The presence of a number of additional alien species was also a characteristic feature of the stands. C. sericea individuals identified in this survey were tall and showed almost no tendency to creep, most likely due to the favourable light conditions. Their leaves were larger (average length 189.2 mm) compared to published data, but the shape of the seeds was characteristic for the species. This is the first re- port of spontaneous occurrence of this species in Warsaw. The largest known concentration of C. sericea stands in the mazovian voivodeship was documented west of Warsaw and includes the Kampinos National Park. However, the small number of existing reports indicates that documentation of this species’ distribution in the region is still insufficient.

    Opis:
    The aim of the research presented here was to determine and compare the habitat conditions of the two adjacent dune areas in the Narew River Valley. For the comparative studies we used the ecological indicator value method and the index of forest soil trophism (ITGL), both of which revealed differences between the investigated habitats. Values of ITGL indicate that in the case of the Uroczysko Serwańce dune, which is covered by a mixed coniferous forest (Serratulo-Piceetum), the habitat is oligotrophic, while the habitat on the Ławki Małe dune is dominated by a not yet fully developed Tilio-Carpinetum plant community which displays a mesotrophic character. Similar differences were observed using ecological indicator values. Soil indices calculated for the oak-hornbeam stand on the Ławki Małe dune indicate the presence of fresh, mesotrophic, humus-mineral soils made of sandy loam or silt substrate with a near-neutral pH. From these results we can deduce that climatic conditions, affected by peatlands, have a greater impact on the development of vegetation on inpeatland dunes than relatively poor soils.
