Forest biodiversity of the Czech National Parks: How to fulfil the primary purpose of the NPs in the present situation
Hédl, Radim; Svátek, M.
2008 - Czech
Biodiversity conservation is one of the primary purposes of the existence of the National Parks, following the IUCN criteria. Management of the Czech NPs faces two main challenges: changing concepts of protected areas and global climatic change. The former concerns an active management on the one hand, and designation of relatively large areas for the wilderness on the other hand. Both approaches must co-exist. The paper then summarizes common and distinct features of the biodiversity in the Czech NPs and stresses the international obligation to halt the biodiversity loss. Ochrana biodiverzity je podle kritérií IUCN jedním z primárních účelů existence národních parků. Management našich NP stojí aktuálně před dvěma hlavními výzvami: změnou pojetí chráněných území a globální klimatickou změnou. V prvním případě jde na jednu stranu o zavedení aktivního managementu, na druhou stranu o ponechání relativně velkých území samovolnému vývoji. Oba tyto přístupy musí koexistovat. Článek dále shrnuje společné i odlišné rysy biodiverzity našich NP a zdůrazňuje, že v kontextu mezinárodních závazků je zastavení úbytku biodiverzity nejdůležitějším tématem současnosti.

Motivation differences of visitation castle ruins and views in Českomoravská vrchovina
Navrátil, J.; Mrňová, M.; Navrátilová, Jana
2007 - Czech
The differences in motivation to visit between castle ruins and views have been studied using statistical analysis of questionnaire survey. According to the result in can be said, that the views are visited especially by introverted visitors. On the other hand the visitors of castle ruins were motivated by more extroverted push and pull effects. However, as the differences among tourist have been found, the result may be influenced by visitor sampling method. Pomocí dotazníkového šetření byly sledovány rozdíly v motivacích mezi návštěvníky zřícenin a výhledů. Ze statistické analýzy plyne, že výhledy jsou navštěvovány návštěvníky introvertně orientovanými. Naopak návštěvníci zřícenin byli motivováni především extrovertně laděnými prvky. Výsledky mohou být ovlivněny strukturou respondentů.

Palaeogenesis of the raised bogs of the Bohemian Forest
Svitavská-Svobodová, Helena
2007 - Czech
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. Prezentace vývoje šumavských rašelinišť podle pylových analýz od období dryasu před 13 tis. lety od formování mělkých jezer; allerod, mladší dryas, preboreál formování rašelinišť s mechy a ostřicemi; boreální keříčkovitá vegetace s Vaccinium, Ericaceae a Calluna vulgaris pokrývá centrální části šumavských rašelinišť; v atlantiku se přeměňuje ostřicová rašelina v rašelinu s Scheuchzeria palustris a v rašelinu s Eriophorum vaginatum; až k subboreálu a k subatlantiku, kdy dochází k rozvoji rašelinišť se Sphagnum sp. i s keříčkovitými formacemi s Vaccinium, Ericaceae a Calluna vulgaris. Vývoj strukturovaných rašelinišť začíná až v subatlantiku a Pinus rotundata dominuje na některých rašeliništích teprve v subrecentu.

Pollen monitoring of the Bohemian Forest in the years 1996 - 2006
Svitavská-Svobodová, Helena; Frantík, Tomáš; Wild, Jan; Melichar, V.
2007 - Czech
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. Cílem dlouhodobého výzkumu pylového monitoringu je stanovit dolet pylových zrn z nižších nebo vzdálenějších poloh, a zjistit tak zastoupení lokální, regionální anebo extra-regionální vegetace. Zjišťuje se kvantativní obsah opadu rostlinného pylu dřevin a bylin za období jednoho roku čili pylový influx/ Pollen Accumulation Rate. Celkém 19 pylových pastí je na Šumavě rozestavěno ve třech vybraných výškových transektech (1)Trojmezenská hornatina a Vltavský luh, (2) na Modravě a na Kvilských pláních a (3) v Královském hvozdu a na Hartmanicku. Vybraná území odpovídají oblastem, z nichž se mohl usazovat pyl na řašeliništích (cathment area), s již známou vegetační paleorekonstrukcí.
