Tourism and recreation in selected area of Šumava mountains
HANULOVÁ, Hana
This work will deal with tourism and recreation in selected areas of Šumava. The aim of the work will assess the current state of tourism in selected areas. Further assessment of the expected structure of tourism development in the designated area, evaluate the structure of current visitors and identify topics suitable for optimizing the field of tourism and recreation.
\kur{In-situ} available phosphorus in forest soils of Bohemian forest lakes watersheds
ČAPEK, Petr
The aim of the study was to test ion exchange resin (IER) bag method for measurement of forest soil phosphorus availability. P-PO4 sorption and elution efficiencies of ion exchange resin AsenXnp (Purolite) were tested. The results showed nearly 100% efficiency of P-PO4 sorption. Average elution efficiency after repeated elution on a glass column was 87 % (each elution step 50 ml 2 % NaOH, 300 ml in total). The amount of available phosphorus was determined in-situ using IER bag method in the litter and organic soil layers of Plešné and Čertovo lakes watersheds. Amount of available phosphorus was 3.6 times greater in soils of Plešné watershed compared to Čertovo watershed.
Structural changes of macrozoobenthic communities in longitudinal profiles of acidified streams in the Bohemian Forest (Czech Republic)
PELTANOVÁ, Jana
Structural changes in macrozoobenthic communities and changes in chemistry in longitudinal profiles of two acidified streams in the Bohemian Forest (Czech Republic) were investigated in 2007. The progress in chemical recovery was evident in both streams, whereas zoobenthos recovery was obvious only in less acidified stream.
Synergy under plants, soil and climate in the Liz catchment in Bohemian Forest in vegetation seasons of 1998 – 2000
Tesař, Miroslav ; Šír, Miloslav ; Polívka, J.
The aim of this study is to quantify the synergy between the vegetation cover, solar radiation, air temperature and soil moisture. Heat balance, potential and actual transpiration, and net entropy exchange is studied in order to determine crucial factors limiting phytomass productivity in dry and warm seasons in Bohemian Forest. Conclusions are crucial factor limiting phytomass productivity in dry and warm seasons in cold climatic conditions is water retention capacity of the soil cover, the phytomass productivity can be quantified by the entropy exchange associated with the latent heat flux.
Pollen monitoring of the Bohemian Forest in the years 1996 - 2006
Svitavská-Svobodová, Helena ; Frantík, Tomáš ; Wild, Jan ; Melichar, V.
The results of the secular pollen monitoring research is focused on the Bohemian Forest where 19 pollen traps were installed on the vertical transects on strategy places gradually covering the areas from natural forest zones to forested-free ones. Three areas were selected in Bohemian Forest (1) the Massif of Trojmezný – Vltavský luh Upper Moldau river valley, (2) Železnohorská hornatina Uplands – Hartmanice region, and (3) Modrava - Kvilda pláně Uplands. The pollen traps were situated in the immediate vicinity of the sampling mire with a known vegetation history, next one on meso-distance at timber-line and the other on the highest peak of the selected transect zone.
Palaeogenesis of the raised bogs of the Bohemian Forest
Svitavská-Svobodová, Helena
The Bohemian Forest landscape is characterized by the montane oligo-ombrotrophic peatbogs. The palaeogenesis of them began from the shallow lakes in the Dryas 13 thousand years ago. In the Allerod, Younger Dryas, and in the Preboreal a forming of the peatbogs with mosses, and sedges was observed. In the Boreal the vegetation of shrubs composed of Vaccinium, Ericaceae, and Calluna vulgaris covered the Central plains of the Bohemian Forest, in the Atlantic the changement of Carex peat to the peat of Scheuchzeria palustris, and Eriophorum vaginatum is mentioned. In the Subboreal and Subatlantic a development of Sphagnum peat followed. The development of pattern raised bogs began in the Subatlantic.
Bottom soils in the rhizospheres of quillworts in the Czech Republic Bohemian Forest
Husák, Štěpán
The bottom soil from the rhizosphere of both quillwort species (Isoëtes lacustris and I. echinospera) was sampled in the Plešné and Černé lakes in the Bohemian Forest by C. Weilner and his collaborators (1996, 1998) and by M. Böhm (2002), and analysed in the chemical laboratory of the Institute of Botany, Czech Academy of Sciences, Průhonice (see Tab. 1.). The results of chemical analyses from the three years are comparable with smoothly increasing values. Only the potassium concentrations decreased from 116.25 mg.kg-1in 1996 to 5.75 mg.kg-1 in 2002 in Plešné Lake. This decrease can be explained by greater flushing of the sediments from the cirque walls into the stands of Isoëtes echinospora, in 1996. From 2004 to 2006 the bottom soils from Isoëtes stands will be analysed twice per year, with more samples from the Isoëtes stands. Nutrients will also be assessed on the radient between the Isoëtes stands and the shores of both lakes.
Algae of Černé Lake in the Bohemian Forest
Lukavský, Jaromír
Algae and Cyanobacteria of Bohemian Forest are presented, as an important part of plant communities. Streams, bogs, arophytic ans subaerophytic standorts, phytoplankton of lakes and cryoseston are discussed and presented in tables and microphotographs.Bohemian Forest is an important refugium of oligotrophic species and a classic locality for therir study.
Productivity of differently managed mountain meadows
Mašková, Z. ; Květ, Jan ; Zelený, D.
A mountain meadow (about 1160 asl) situated in the Šumava NP/BR was subjected to 3 treatments applied in mid-July in 4 succesive years: (i)mowing, (ii)mulching, (iii)no management. Seasonal courses of aboveground biomass varied between 0,35-0,5 kg.m-2 in all treatments and years while belowground biomass did between 6-9 kg.m-2. R/S ratio varied between 6-18, being mostly highest in the mown treatment. Litter dry weight varied mostly between 0,2-0,8 kg.m-2, being usually hightest in the unmanaged treatment. Seasonal courses of the above 3 production characteristics were highly variable. Estimated average annual aboveground net production was 0,6-0,7 kg.m-2 for all treatments and years.
Integrated tourism in the Bohemian Forest and its investigation in the European context
Bartoš, Michael ; Kušová, Drahomíra ; Těšitel, Jan
International project titled 'Supporting and promoting integrated tourism in EuropeŽs lagging regions (SPRITE)ö is aimed at comparing conditions to conduct such a type of tourism within six selected European countries ů Czech Republic, Greece, France, Ireland, Spain and United Kingdom. Šumava Mts. region was selected as one of model areas. By this project, tourism is analysed as a multifaceted phenomenon which can be described as interplay among six principal actors involved ů tourists themselves, host community, businesses, resource controllers, institutions and gatekeepers. Presentation of selected results and their comparison in the international scale is a main subject of discussion in this article.
