Black locust was introduced in Hungary between 1710 and 1720. The first large black locust forests were established at the beginning of the 18th century on the Great Hungarian Plain stabilizing the windblown sandy soil. In the country, black locust occupied 37.000 ha in 1885, 109.000 ha in 1911, 186.000 ha in 1938 and 415.000 ha in 2009. At present, it is the most widely planted species in Hung...

Fire, as a natural ecological disturbance factor in forest, this study located in the Marivan region, Northern Zagros forest, and western Iranian state of Kurdistan. In each burned and unburned area 30 circle sample plot (1000 m2) were collected by randomized–systematic method in the 100×200 m net (in total 60 plots). In every sample plot the kind of species, number of tree, the heig...

More than 1.5 M ha of eucalypt plantations have been established in south China, increasing by about 100,000 ha y. Productivity is uneven and low, only about 25-50% of the world average for eucalypt plantations. Most land available for eucalypts are degraded oxisols and utilsols which also are acidic, highly leached and deeply weathered. Phosphorus deficiency is very severe and its availability...

Measurements of the statistical characteristics of umbra and sunflecks at different depths inside a willow coppice — Salix viminalis and Salix dasyclados — were carried out at Tartu Observatory, Tõravere, Estonia, in 1997. A new instrument, the sunfleck indicator, constructed by M. Sulev, was used. This instrument, moving perpendicularly to rows in the horizontal direction, counts the number an...
