Cím:	Nonlinear height-diameter models for three woody, understory species in a temperate oak forest in Hungary / Tamás Misik, Károly Antal, Imre Kárász, Béla Tóthmérész

Megjegyzések:	Information about the diameter and the height of woody species is fundamental to developing growth and yield models inforest stands. Ten nonlinear height?diameter functions were fitted and evaluated for the site. The dataset consisted of 957 selected individuals of three dominant woody species (Acer campestre L., Acer tataricum L., and Cornus mas L.) and represented a wide range of woody species sizes. Changes in these equations following dieback of oak canopies were analysed. Residual standard error (RSE) results of the two-parameter functions showed that the "Wykoff et al. 1982" and "Bates and Watts 1980 ? Ratkowsky 1990" functions had lower RSE values in 1972. After oak decline the "Larson 1986" and "Bates and Watts 1980?Ratkowsky 1990" functions had lower values. The RSE data for the three-parameter functions showed that the "Pearl and Reed 1920" function had fitted RSE values at the start of thelong-term study. After the canopy decline function, the "Ratkowsky 1990" function RSE value was lowest for A. campestre and C. mas. "Pearl and Reed 1920" was the best-fitted function for A. tataricum. Height?diameter equations increase our knowledge about the growth of these species, which will enable us to improve management planning in oak forests.

Cím:	Short-term changes in height-diameter relation of two maple species and European cornel of understory in an oak forest in Hungary on the basis of two-parameters model / Tamás Misik, Károly Antal
Dátum:	2016

Megjegyzések:	Forest understory species such as shrub and herbaceous layer, have received little attention in long-term studies. Knowledge of the diameter and the height of trees are fundamental for developing growth and yield models in forest stands. Overstory composition of the Síkfőkút Project site was dominated by sessile oak?Turkey-oak forest (Quercetum petraeae-cerris Soó 1963). Similarly to other European countries an oak decline occurred in Hungary oak woodlands at the end of 1970's and about 63% of the oak trees perished in our site. The potential for oak species regeneration was a very low over the period of 1982-2012. Four nonlinear height-diameter functions were fitted and evaluated for Síkfőkút site based on a data set consisting of 2025 individuals for three dominant woody species (Acer campestre L., Acer tataricum L. and Cornus mas L.) and detected any short-term changes in these equations following dieback of oak canopies. These height?diameter equations increase our knowledge of the growth of these species; therefore will enable us to improve management planning in oak forests.
