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. In this study the authors analysed data with relation to the date of the census, climatic factors (cloud cover, air temperature, wind and precipitation) and the main two habitat types (closed mature forest and ecotone). The results of the study show that the numbers of dominant bird species change significantly during the particular census dates within one season, mainly with respect to bird detectability.

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 was calculated by structural indices according to Füldner (1995). Additionally, the following quantitative parameters were analysed: number of trees (tree density), basal area, standing volume, total yield production, total annual volume increment, total tree number decrease including thinning, self-thinning and abiotic injurious factors. The most suitable structure documented by the above-mentioned indices was found on the plots managed by free crown thinning. Similarly, from the quantitative aspect, the highest values (total production according to basal area) were reached on the plot tended by free crown thinning (thinning interval of 5 years). As for the total production according to merchantable volume, the highest values were obtained from the plot treated with heavy thinning from below.

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 A total of 254 units were analyzed, 195 of them harvested and 59 withdrawn from the auction at a limit price.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 2,045 CZK.m-3. Upon 91-100% coniferous ratio the winning prices ranged between 766 and 1,743 CZK.m-3. The results obtained indicated a statistically significant difference between the average winning prices in stands with more than 90% conifers and in stands with more than 90% broadleaved species.

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 located in the young spruce stands, and therefore the silvicolous species prevail. Neodineura arquata represents a new genus and species and Heptamelus dahlbomi a new species for the fauna of the Czech Republic. Nine species have been classified as endangered and twenty-one species have been classified as vulnerable. Pristiphora robusta has been deleted from the list.

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 were prepared from diseased tissues. All isolates were found pathogenic and identified as Gram-positive, rod-shaped and spore-forming. The isolates were identified as Bacillus pumilus, based on morphological and biochemical characteristics, and also on 16S rRNA gene sequence analysis. Pathogenicity studies of different B. pumilus isolates revealed that they have a potential to cause the soft rot disease in pine seedlings and symptoms of wetwood disorder in young Scots pine trees.

Title: Australia's transition to management of myrtle rust Abstract: 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 noneradicable pests, one of which was for the myrtle rust pathogen, with the goal of using the outcomes of the pilot programs to guide the ongoing development of formal transition arrangements.
