My objective of my work is to develop prediction models for tree age
based on diameter at breast height (dbh). Study species: Abies borisii-regis, Fagus sylvatica, Pinus nigra, Quercus trojana, Quercus cerris.
I have looked at these papers:
(Dobrovolný, L. & Tesař, Vladimír. (2010). Growth and characteristics of old beech (Fagus sylvatica L.) trees individually dispersed in spruce monocultures. Journal of Forest Science
Loewenstein, Edward & Johnson, Paul & Garrett, Harold. (2000). Age and diameter structure of a managed uneven-aged oak forest. Canadian Journal of Forest Research-revue Canadienne De Recherche Forestiere - Canadian Journal of Forest Research 30(7):1060-1070
Łukaszkiewicz, Jan & Kosmala, Marek. (2008). Determining the Age of Streetside Trees with Diameter at Breast Height-based Multifactorial Model. Arboriculture and Urban Forestry.
Rohner, Brigitte & Bugmann, Harald & Bigler, Christof. (2013). Estimating the age–diameter relationship of oak species in Switzerland using nonlinear mixed-effects models. European Journal of Forest Research. 10.1007/s10342-013-0710-5. )
Cοuld anyone help me to find an accurate way to estimate tree age [Abies borisii-regis, Pinus nigra, Quercus trojana] using DBH?
Thank you.
Look out for species specific regression equations involving age and dbh.
Foresters typically use an increment borer, and count the annual rings.
Hope this demonstration will help.
