Knowledge of the structure and diversity of bird populations in forest ecosystems is important for the conservation of forest biodiversity. The results of bird population studies in forest ecosystems are influenced by the detectability of the subject birds. In spite of this fact, the detectability of birds in different forest habitats is often paid little attention. The aim of the present study is an assessment of the key factors which are important for the detectability of birds in floodplain forest ecosystems. The paper analyses the detectability of bird species in floodplain forests (Litovelské Pomoraví, Czech Republic) during the period 1998-2012....

The paper deals with assessment of a long-term experiment (45 and/or 53 years of investigation) in the 90-years-old European beech (Fagus sylvatica L.) stand in a selected region of East Slovakia. The research was performed from 1960 to 2013 on subplots managed by four different methods: (i) plot with heavy thinning from below (C grade according to the German forest research institutes from 1902), (ii) plot with free crown thinning (thinning interval of 5 years), (iii) plot with free crown thinning (thinning interval of 10 years) and (iv) control plot (with no thinning). The diameter and height structure...

The first competitive open tender called "Standing timber sale" was executed in 2010. The aim of the paper was to conduct complete collection of data from online tender catalogues and to analyze the data with respect to the coniferous/broadleaved ratio. A total of 254 units were analyzed, 195 of them harvested and 59 withdrawn from the auction at a limit price. Out of the harvested units, 125 units with a maximum 10% coniferous or broadleaved tree representation were selected, while the remaining 70 units showed a varying coniferous/broadleaved ratio ranging from 11% to 89%. Upon 0-10% coniferous ratio the average winning price ranged between 330 and...

Sawflies were collected in the northeast of the Czech Republic using Townes type Malaise traps. Traps were placed in eleven young Norway spruce (Picea abies) forests during the period from 1998 to 1999. Localities cover altitudes from 230 to 1,000 m a.s.l. In total, 285 species of Symphyta have been recently known from the study area (Xyelidae - 1, Pamphiliidae - 7, Argidae - 10, Cimbicidae - 3, Diprionidae - 5, Tenthredinidae - 252, Siricidae - 1, Xiphydriidae - 1, Cephidae - 5). The majority of the species have large distributional ranges and their host plants are forest tree species. Most of the sawflies were obtained from Malaise traps...

Large bleeding lesions on stem and branches of pine trees, wet black spots and depressed cancer wounds of different sizes at the base of knots, dying off the bark around knots and sapwood exposure over a large area, wilting, yellowing and shedding of needles on the individual branches and whole crown may indicate the presence of pathogenic bacteria. Monitoring the health of pine plantations in Lviv and Minsk regions showed the spread of diseases that can be caused by bacteria. In order to identify the pathogenic bacteria associated with pine vascular diseases, we collected needles, bark and sapwood from symptomatic trees. Ten potential pathogenic isolates...
Australia's transition to management of myrtle rustShort Communication

Puccinia psidii sensu lato was detected in Australia in 2010 causing myrtle rust. A nationally cost-shared eradication program was conducted based on well-established emergency response arrangements for incursions of emergency plant pests into Australia, but it was ultimately decided that the pest was not eradicable from Australia. At this time, no formal mechanisms existed to provide a clear path for decision making and cost-sharing when transitioning from an eradication focus to long-term management of a plant pest. In 2011, the Australian Government established and funded a set of pilot transition to management programs for a number of...
