Predation by introduced stoats is now considered a major threat to the population viability of several New Zealand endemic bird species. Historically stoat research and management has focused on beech forests and little is known about the ecology of stoats in the alpine grasslands occurring above the natural altitudinal limit of beech forest. Several stoat control operations in beech forest val...

Leaves from 145-year-old and 44-year-old beech trees were harvested during 1991-1993. Chlorophyll (Chi) and redox components of the thylakoid membrane, including P-700, cytochrome / (C yt/) and D, protein, were determined with the following results. Chi a + b, P-700 and C y t/p er unit of fresh weight (FW), dry weight (DW ) and leaf area (LA ) increase significantly during leaf development. Thi...

Determining the productivity of forest sites through various classification techniques is important for making appropriate forest management decisions. Forest sites were classified using direct and indirect (site index) and remote sensing (Landsat 7 ETM and Quickbird satellite image) methods. In the direct method, forest site classifications were assigned according to edafic (soil properties), ...

There are few data on fine root biomass and morphology change in relation to stand age. Based on chronosequences for beech (9-140 years old), oak (11-140 years) and alder (4-76 years old) we aimed to examine how stand age affects fine root biomass and morphology. Soil cores from depths of 0-15 cm and 16-30 cm were used for the study. In contrast to previously published studies that suggested th...

Aim of study: Information about the diameter distribution a stand is key resource to determine planning strategies, silvicultural treatment options and product variety. In this study, distributions Fagus orientalis Libsky stands located in Karabük region were researched, relationship between parameters Weibull function variables was investigated.
 Area Data used study obtained from pure Or...

To identify why tree growth differs by afforestation type is a matter of prime concern in forestry. A study was conducted to determine why oriental arborvitae (Platycladus orientalis) grows better in the presence of black locust (Robinia pseudoacacia) than in monoculture. Different types of stands (i.e., monocultures and mixture of black locust and oriental arborvitae, and native grassland as a...

knowledge of the stand condition and the gradual replacement of tree species in different development stages and phases provide appropriate information related to the close to nature treatments. stem exclusion phase is one of the important development phases in the forest stands development. the aim of study was to analyze the characteristics of dead trees in the stem exclusion phase in the les...

Recently, the beech forests of southern Central Europe (including large parts of the Illyrian region) have been syntaxonomically revised, using a TURBOVEG database containing more than 5800 relevés, mainly from Austria, Switzerland, Germany, the Czech Republic, Hungary, Slovenia and Croatia. The same TURBOVEG database was used to calculate patterns of alpha and beta diversity within beech fores...
