“…This rather small area includes various types of forest soils from infertile to very nutrient-rich. Boreal very rich forests are characterized by mixtures of broad-leaved and coniferous trees, and by soils with structural complexity and values of pH indicating near neutrality [40]. Their understorey vegetation is therefore denser both vertically and horizontally than in less fertile soils.…”

Abstract:In Finland, forest site types are used to assess the need of silvicultural operations and the growth potential of the forests and, therefore, provide important inventory information. This study introduces airborne laser scanner (ALS) data and the k-NN classifier data analysis technique applicable to the site quality assessment of mature forests. Both the echo height and the intensity value percentiles of different echo types of ALS data were used in the analysis. The data are of 274 mature forest stands of different sizes, belonging to five forest site types, varying from very fertile to poor forests, in Koli National Park, eastern Finland. The k-NN classifier was applied with values of k varying from 1 to 5. The best overall classification accuracy achieved for all the forest site types and for a single type, were 58% and 73%, respectively. The conclusion is that when conducting large-scale forest inventories ALS-data based analysis would be a useful technology for the identification of mature boreal site types. However, the technique could still be improved and further studies are needed to ensure its applicability under different local conditions and with data representing earlier stages of stand development.

“…Therefore the small and spare herb-rich patches are quite often missed. However, small scale herb-rich stand inventories by using permanent sample plots (1 are) with detailed vegetation analysis squares (1m 2 ) have been conducted in Koli National Park (Koli NP) to quantitatively assess their floristics composition and site type classification (Hokkanen 2006). …”

“…This relatively narrow area displays a wide range of site type classes from infertile to very nutrient-rich (herb-rich) soils with values of pH indicating near neutrality (Hokkanen 2006). In addition, the number of vascular plants and moss species are much higher than in other parts of the region (Hokkanen et al 2003).…”
