KRKONOŠE MTS.

• National park (1963)
• Krkonoše/Karkonosze Biosphere reserve (1992)
• Weak subalpine nature vs. tourism
• grassland, peat-bogs, corries, Swiss Mountain
  Pine stands,
• trails roads, chalets, viewpoints, tourists, ...

Indicators individuals vs. communities

• expansion invasion - pictures of individuals
• summarising research - mapping of communities
  (all or only several types)

18
Area of interest

• Krkonoše Mts. - high tourism exploatation and
  outstanding nature
• alpine nature - little visible influence on
  vegetation
• mountain veg. belt - giant impact of forestry
• subalpine communities - effect of trails best
  visible

19
Area of interest II

• 6.8 km2 on Czech side until 1999
• ca 10 km2 on both Czech and Polish sides since
  1999

22

• target 1 Find out the extent of non-natural
  growths
• GPS - position info (database)
• GIS - maintenance and evaluation of data

23

• target 2 Find out main reasons for
  distribution/extinction
• GIS - combination of GPS data (e.g. average width
  of TMV vs. trail stabilising material)
• other sampling methods (counting tourists,
  botany, water, soil etc.)

24

• target 3 Propose improving activities
• complex analysis of all data, field observations
  and experience

• how many idividuals are 1 point?
• roads/trails/paths (area/line)
• community (area/0) - comm. width lt GPS accuracy
