Data Acquisition and Methods of Evaluation

Lithology & Soils
  Soil physical and -chemical Analysis on 431 Profiles (Drilling Stock- and Key Profiles)

e.g. Description and Determination of:

  • 'Properties' and 'phases' according to Definitions of FAO, Depth of Soils,
  • Intensity of Rooting in different Horizons,
  • Humus Fashion and Richness,
  • Field Capacity (FC), available FC,
  • Fine Ground (gravimetric) and Content of Grit, Texture of Fine Ground,
  • Compactness, Unit Weight (Skeleton and Fine Ground),
  • Pore Space (Volume) and Pore Space Distribution,
  • Total Mineral Content and total Clay Mineral Content,
  • pH Values and Electric Conductivities (EC),
  • Carbon Content (organic, non-organic),
  • Total Nitrogen Content,
  • Potential Content of Calcium (limestone) and Magnesium Carbonate (Dolomite),
  • Additionally, simulations and Risk Assessments of Erosion were carried out.

  Climate Data Acquisition from 1989-1992 with CM 10 (21X) 'automatic weather stations' manufactured by CAMPBELL SCIENTIFIC Ltd., from the hilly landscape above Dörtyol to the treeless subalpine belt (500, 950, 1.600 and 2.100 m a.s.l.)
The following parameters were measured:

  • Soil and Air Temperature (-20, -40, -80 cm below surface and 100/200 cm above ground)
  • Wind Direction and Velocity
  • Global Radiation
  • Amount of Precipitation, Frequency and Intensity
  • Soil Moisture in -40 and -80 cm depth

Flora & Vegetation
  [gif 8K: Doronicum spec.] Presentation of floristical-geobotanical and dynamic aspects of vegetation distribution, especially analysis of the causality of pattern and distribution of extrazonal vegetation.
The following documentation and measurements were carried out:

  • Documentation of the flora of the research area (a Herbarium with about 2.500 specimen has been established)
  • Recording of the Vegetation (251 relevees with data of dominance, abundance and phenology of 5 different strata)
  • Geobotanical Evaluation of documented species and comparison with areas of similar climatic conditions (e.g. Balkan Peninsula, Pontus Region)
  • Development of Life Form Spectra
  • Realisation of Synoptical Classification (with all relevees) and Numerical Ordination (with all variables measured)
  • Mapping of Vegetation and Presentation of Geobotanical Units
  • Development of well founded hypotheses regarding the 'potentially possible vegetation' under different degrees of human impact (stages of Hemeroby)

Discussion of vegetation dynamics in the future (especially the extrazonal vegetation, incl. endemics) under different economic pressure. This on the background of the unique climatic conditions of the westerly exposed slopes of the Amanus Mtn. range and different hypotheses of their origin.
