Modelling dominant height growth and site index curves for rebollo oak (Quercus pyrenaicaWilld.)

Abstract: -A dominant height growth model and a site index model were developed for rebollo oak (Quercus pyrenaica Willd.) in northwest Spain. Data from 147 stem analysis in 90 permanent plots, where rebollo oak was the main species, were used for modelling. The plots were selected from the National Forest Inventory at random in proportion to four biogeoclimatic stratums. Different traditional and generalized algebraic difference equations were tested. The evaluation criteria included qualitative and quantitative examin… Show more

“…SD = Standard Deviation the guide curve method, 2) the parameter prediction method, and 3) the Algebraic Difference Equation Method. Although the three methods are not mutually exclusive, the difference equation method has been the preferred form and widely used by numerous authors in order to develop site index curves (BAILEY and CLUTTER, 1974;CIESZEWSKI, 2003;CARVALHO and PARRESOL, 2005;DIÉGUEZ-ARANDA et al, 2005a, 2005bADAME et al, 2006;DIÉGUEZ-ARANDA et al, 2006).…”

“…Taking into account that the average height of the stand may be affected by certain types of thinning, but that within a wide range of stand densities the height growth does not seem to be affected -especially when the comparison is restricted to dominant trees (BAILEY and CLUTTER, 1974;CLUTTER et al, 1983) -, the most common approach in determining site productivity involves the use of a site index. This may be defined as the dominant height of the stand at a specific base age (BARRIO and DIÉGUEZ-ARANDA, 2005;ADAME et al, 2006).…”

“…After clear-cutting a subsequent shoot or root regeneration occurred. Over the last 50 years this activity was progressively abandoned because of rural emigration to the cities and the introduction of fuel heating in household [7]. The budget for forest administration is insufficient to perform an alternative forest management in high density coppices needed to avoid diseases, reduce forest fire risk or promote the health and growth of stands.…”
