Measurement of standing stock

Methods:

  • Classical full calipering using ÚLT tables and measuring the tree height with laser altimeter.
  • Volume equation used in the frame of statistical inventory on sample plots.
  • Local models of stem form proven in concrete stand (area).

Size of enquired unit:

  • Not limited, on larger area we use inventory enquiry on sample plots.

Output:

  • Timber volume under bark or over bark according single tree species on enquired units.

Calculation of the standing volume retroactively

Methods:

  • Finding the relationship between stump and breast height, modeling of the diameter distribution and the construction of height diagram. The volume is taken from ÚLT tables.
  • Variation with the calculation of the tree volume by a local model of stem form.

Size of enquired unit:

  • Not limited, on larger area we use inventory enquiry on sample plots.

Output:

  • Reconstructed timber volume under bark or over bark according single tree species on enquired units.

Valuation of the forest condition by a statistical forest inventory

Methods:

  • Valuation of the forest condition on the sample plots of statistical inventory. On concrete forest property we generate a net of sample plots and we make a measurement of monitored quantities according to clients demand by Field-Map technology. The calculation of monitored quantities is fully computerized.

Size of enquired unit:

  • Not limited, it is possible to use unit „forest stand“ or „forest compartment“ and higher.

Output:

  • Monitored quantities are fully in the competence of the client. At every quantity we mention a statistical error.

Game damage inventory on the forest properties of different size

Methods:

  • Game damage inventory is based on statistical enquiry in the net of accidentally generated sample plots, so that the level of subjectivity is suppressed by a maximum. On every sample plot we evaluate 10 individuals from regeneration as close to the centre of the plot as possible. The calculation of monitored quantities is fully computerized and is running under Field-Map software.

Size of enquired unit:

  • Not limited, it is possible to use unit „forest stand“ or „forest compartment“ and higher.

Output:

  • Height category of the regeneration
  • Crop of the side and terminal shoot
  • Age of the crop damage
  • Prevention against crop
  • Bark stripping and mechanical damage on the stem
  • Age of the bark stripping and mechanical damage
  • Protection against bark stripping/browsing

Operational survey on forestry objects of small size (sample plots, forest reserves etc.)

Methods:

  • By the help of Field-Map technology it is possible to make an operational polarization and mapping of the objects, that serves to forestry practice, research and nature protection. It could be sample plot, important tree, habitat of rare animals or plants, mapping vegetation cover or dead wood in forest reserves.

Size of enquired unit:

  • It is possible to work from the level of single spot to the the size of some hectares.

Output:

  • Available in standard GIS formats, according to clients requirement
