According to the study results, the educational status of hunters was the following: the group with the primary school level made 7.8%, with the secondary school level made 4.5%, with the high school level made 9.9%, with the associate level made 0.6%, with the undergraduate level made 3.9%, with the master level made 2.7%, and with the unknown educational status were determined to be 70.06%. Considering the professional status, it was determined that 79,3% were of unknown status, 1.6% were retired persons, 3.4% were tradesmen, 1.6% were workers, 2.9% were public sector employees, 0.8% were students, 2.0% were employees from the private sector and 8.4% were self-employed persons. It was revealed that for gaming the hunters visited Aksu State Hunt, Serik State Hunt, and Gebiz State Hunt (3.29%) most frequently. The least preferred gaming areas were Gazipaşa Sıvastı Çığlık State Hunt and Kaş Asas Hunt (1.41%). Usually, hunters prefer to gun for common blackbird (Turdus merula L.) foremost (9.69%) and coot (Fulica atra L.) least of all (1.07%). As is evident from this study, socio-demographic profiles of hunters in Antalya province, Türkiye, and in Europe appears to be similar. However, a significant difference was observed in the number of women hunters registered. While the average number of women hunters in some European countries reached 10.5%, no women hunters were registered in Türkiye.\u0000Keywords: game management, information system, hunter, game animals, wildlife, profile ","PeriodicalId":55404,"journal":{"name":"Baltic Forestry","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47828565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To tackle the threat, many countries have designated surveys that are typically conducted at the probable ports of entry. For Finland, the most north-eastern region of the European Union (EU), such site is the border with Russia and the imports of coniferous roundwood and wood chips. In this paper, we describe the monitoring systems based on pheromone-trapping for three EU-wide quarantine pests: Dendrolimus sibiricus, Polygraphus proximus and Bursaphelenchus xylophilus. We also list the non-target species caught in an exploratory survey using pheromone traps. During the three years of survey, no quarantine pests were detected, but 30 other species of insects were caught. Therefore, the monitoring – despite not detecting the target pests – provided information about the abundance of other species. As insect diversity reflects the status of the surrounding environment, the value of such data should be increased via co-operation among research institutes.\u0000Keywords: wood import, invasive alien species, monitoring, pest, forest damage, insect ","PeriodicalId":55404,"journal":{"name":"Baltic Forestry","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46911461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to increasing forest protections, more deciduous stands will reach the old-growth stage. Thus, data on the carbon storage potential in such areas are essential. We aimed to establish a benchmark for carbon stocks of the main carbon pools in old-growth deciduous hemiboreal stands. Carbon pools were calculated from measurements in forty old-growth (104–148 years-old) deciduous stands in forests on fertile mineral soil. The carbon stock in these stands is distributed across tree biomass (~ 60%), mineral soil (~ 30%), the forest floor (~ 5%), and deadwood (~ 4%). Living tree biomass and deadwood carbon pools were closely associated with stand parameters: dominant tree species, standing volume and stand density. As the stand ages and tree dieback occurs, the significance of individual large trees to maintain high density and standing volume, thus also the carbon stock of the stand, rises. Reliance on a small number of large trees makes the carbon storage in old-growth stands fragile and easily affected by natural disturbances. It happens at an earlier age for species with a relatively short life span, like birch and aspen. Our data from stands with the limited recent influence of such disturbances provide a benchmark for carbon storage potential in old deciduous stands.\u0000Keywords: carbon pools, tree biomass, deadwood, forest floor, soil, birch, European aspen","PeriodicalId":55404,"journal":{"name":"Baltic Forestry","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43854567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the eight years, the total poplar biomass production was significantly different (P ≤ 0.05) in poplar-based configurations and ranged from 9.1 to 13.4 mg ha–1. The highest carbon storage of 6.5 mg ha–1 was observed in configuration E. Crop production of canola and wheat in configurations B, C, D, and E, did not show a significant difference with pure crop cultivation, while configuration A was significantly lower. Our result indicated that configuration E, with the highest total biomass production but no significant difference in crop production, is the optimum system of poplar-based agroforestry in regions with similar temperate climate conditions of Northern Iran.

This research seeks to fill the knowledge gaps to some extent. The paper describes the population variability of vegetative organs of Larix gmelinii growing in Eastern Transbaikalia, Russia. The problem is approached by studying a complex of morphological characters of natural Larix gmelinii populations along the Transbaikalian rivers. Also, the habitat conditions of Dahurian larch coenopopulations were recorded for further analysis of the connection between the morphological characters and the habitat parameters. The study established the values of morphological characters and their variability limits and traced the localization patterns of the morphological forms of Dahurian larch in the river basins. Moreover, the morphological characters of larch vegetative organs were found to relate to the location and the habitat conditions of the coenopopulations. The research materials can be useful for correcting the larch seeding zones in Transbaikalia, establishing larch genetic reserves, and introducing new morphological forms into the selection for urban beautification and protective plantations.

For this purpose, the study was carried out in a Scots pine plantation with an average of 2,160 m altitude in the forest edge rangeland area between 2012 and 2015. The study area was divided into 12 plots in total, with each plot 0.2 ha in size. The experiment was laid out in a randomized complete block design with three replications in a split plot arrangement keeping Scots pine sapling height (0–60 cm, 61–90 cm and > 90 cm) and four grazing treatments (Ungrazed, grazed in June, grazed in July, grazed in August). The relative diameter and height increments were determined along with the survival percentages for the saplings. According to the results; overall, less than 1% of saplings were found to be damaged as a result of the treatments. In all the grazing plots, the Scots pine saplings had more diameter and height increment than the ungrazed plots on average. In conclusion, controlled cattle grazing in July and August can provide both good quality forage for regional livestock and positive contributions to the growth of saplings, provided that saplings have more than 60 cm in height.\u0000Keywords: Scots pine, plantation, sapling, growing, forest, grazing","PeriodicalId":55404,"journal":{"name":"Baltic Forestry","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49574037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to determine whether the nest site characteristics of the Common Buzzard Buteo buteo – a generalist raptor – have changed over time due to ongoing changes in forests and agricultural areas that are highly important for its breeding. A comparison of Common Buzzard nest sites occupied in 2002–2004 with nest sites occupied in 2017–2018 in commercially managed forests indicated certain changes. Common Buzzards preferred to nest in more mature stands with the higher proportion of deciduous trees in composition of the first tree layer. The location of stands in regard to agricultural areas did not shape habitat choice. The oak was most important nests tree. The nest sites of the Common Buzzard remained similar in terms of location within the landscape, however, age of stands used for nest significantly increased. In summary, these results suggest that Common Buzzard nest site selection pattern was driven by stand level decisions, but were not shaped by the landscape features. These findings indicate that behavioural plasticity typically assumed for this ubiquitous raptor may not necessarily act at the all levels of nest site selection process, which may further indicate species potential sensitivity to the changes in forest utilisation intensity.\u0000Keywords: habitat selection, raptor, forestry impact","PeriodicalId":55404,"journal":{"name":"Baltic Forestry","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48713086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As European policies turn into Green Deal, ecological forestry systems, which aim to increase or at least not reduce biodiversity while maintaining high forest productivity, are becoming particularly relevant. This study examines distribution regularities of the lower storeys of main tree species in fertile not wet habitats of forest communities composed of pioneer deciduous tree species, the understanding of which will allow the development of forestry systems that exploit the natural forest regeneration potential. We used stand-wise forest inventory data on Betula spp., Populus tremula, Alnus incana mature and overmatured stands. We analysed how lower storeys are distributed in the stands of different tree species according to soil conditions, the age, stocking level and mixture. We found that most of stands are not in the second story and understory, from which new stands can be formed. Betula forests have the greatest potential for regeneration, and Alnus incana forests have the lowest one. The most important species of the second story and understory is Picea abies, rarer Fraxinus excelsior and Tilia cordata, other species are more random. With an increasing forest mixture, the second story and understory are found more often. To reduce clear-cutting in the fertile forests of pioneer tree species in forestry, we need to focus on measures to allow the development of lower storeys of the major climax tree species.
