The conservation of genetic diversity is crucial for the maintenance of the adaptability of forest tree populations. Main international and regional initiatives for the conservation of forest genetic resources are presented in this article. Key players at the international level are the FAO and the IUFRO, while at the European level MCPFE and EUFORGEN have been most active. During the last decades, conservation of forest genetic resources has changed its focus, from the maintenance of economically important species, provenances or genes, to the enhancement of the adaptability of forest populations towards future environmental changes. Thus, the conservation of forest genetic resources, besides the activities connected with ex situ collections of reproductive material and tree breeding programmes, involves forest management measures and guidelines and becomes a cross-cutting issue, not only for forestry, but for other economic activities influencing forests as well.

Despite the large number of scientific papers dealing with conservation of forest genetic resources, research about the attitudes and evaluation of representatives of key stakeholders in the forestry and nature protection sectors, towards this issue, have not been sufficiently represented so far in Serbia. The aim of this paper was to study the attitudes of representatives of key public institutions (administrative and professional), enterprises, educational and research organizations in the forestry and nature protection sectors, towards the factors that threaten biodiversity, conservation methods, state of seed sources in Serbia and proposals of measures to improve forest genetic resources. The methodology used in the paper is an approach to the research on conservation of forest genetic resources which is used in the social sciences. The survey included a total number of 32 respondents in the territory of the Republic of Serbia. According to the key stakeholders? opinion, urbanization and infrastructure construction (average score 4.1) have the greatest negative impact on biodiversity; conservation of forest genetic resources in natural populations through designation of seed stands is rated as the most important in situ method (average score 4.60), while establishment of seed orchards and provenance trials are rated as the most important ex situ conservation methods (average score 4.19). From the analysis of respondents' attitudes, it can be concluded that the conservation of forest genetic resources through designation of seed stands (72%) and conservation in protected areas (63%) are methods that gave the best results in Serbia. However, the majority of respondents (about 60%) stated that seed sources in Serbia do not have an appropriate structure and spatial coverage. In addition to the professional activities and support from the institutions, the majority of respondents believe that it is necessary to intensify activities to promote conservation of forest genetic resources.

The aim of the article is to generalize the information presented in the FAO report ‘The State of World Forest Genetic Resources (FGR) and in the reports on the state of forest genetic resources in Ukraine and other countries. Results and Discussion. To draw up the World Report, the information was provided by 86 countries which occupy 76% of the earth's surface and involve 85% of the total forest area. The countries’ reports cover 8,000 species of trees, palm trees and bamboo, among which about 2,400 are economically important; at that, information at the genetic level is only available for 500 to 600 species. The vast majority of important for environmental protection species (84%) are indigenous, in contrast to those economically important, 85% of which are introduced species. About 50 indigenous and non-native species of forest trees are used in the forestry of Ukraine. 26 of them are given as high-priority ones. They are used to produce wood, pulp, fuel, non-timber products, as well as to create protective plantations. The total number of species and subspecies in the world that are preserved in situ is almost 1,000, with about 500 of them – in Asia and almost 200 in both Europe and Africa. In Ukraine, there are about 30 of such species. In cases where in situ conservation is problematic, alternative methods are used, namely ex situ. The total number of species that are conserved ex situ is 1,800; at that, 1,025 of them grow in Africa, 401 – in Europe, 389 – in Asia, 372 – in Latin America and the Caribbean, 265 – in North America, 102 – in the Middle East and 57 species – in Oceania. In Ukraine, they make a stock of the seeds of more than 130 tree and shrub species, including decorative ones. Man-made forests are created with more than 20 species of trees annually. Non-native species of woody plants in the forestry of Ukraine make 39%. Methodological approaches to the study of genetic variability involve analysis of biometric, morphological and biochemical characteristics, as well as DNA markers. They analyze genetic variation as in field studies in provenance trail and progeny tests, so in laboratory studies. Conclusions. The basic tasks for the forest genetic resources conservation is to develop and implement national in situ and ex situ conservation strategies for sustainable use of FGR, to strengthen the role which forests and protective stands play in the in situ FGR conservation, and to identify first-priority measures at the species level. FGR conservation strategies should contribute to both ecosystem restoration using appropriate genetic material and adaptation to climate change along with mitigating its impacts.

In 1933, Joaquim Vieira Natividade established an experimental field with oaks and related genera at Mata Nacional do Vimeiro, Portugal. This experimental area includes the only Portuguese plots with the hybrid Quercus x hispanica hybrid ‘Lucombeana’ (Quercus cerris x suber) with seeds obtained from the Cambridge Botanic Gardens.In 1962-1965, their offspring were included in this area. Those plots integrate an ex situ forest genetic resources, representing a unique population for understanding the structure, function and evolution of the genome (genomics) and its gene expression (transcriptomics). In all progenies, with approximately 60 years, it is evident the segregation for several phenotypic characteristics, specifically in the cork formation and in the leaf shape. Based on that, two projects were developed with this plant material. The first was focused on finding out the molecular basis responsible for the variation in cork and the other on association genetic studies. The aim of this work is to allow access and sharing of knowledge about this genetic material in accordance with the established by FAO in the State of the World’s Forest Genetic Resources report. Information about these hybridsis available at PANGAEA repository.

This paper presents the results of an analysis of the existing seed sources managed by SE ?Srbijasume?. A proposal has been given for new seed sources to be designated in forest areas. This paper highlights the significance of seed sources as a form of in situ conservation, as well as the necessity of establishing seed orchards as a form of ex situ conservation of forest genetic resources, which improves the mass production of reproductive material of forest trees characterized by good genetic quality.

The present study was carried out to advance towards the conserving threatened forest tree species of Bangladesh under ex-situ conservation system. Four thousand plants of forty eight threatened forest tree species were conserved at three areas, namely Institute of Forestry and Environmental Sciences, Chittagong University; Radar Unit of Bangladesh Air Force, Cox‟s Bazar; and the Keochia research station of Bangladesh Forest Research Institute. The average 90-95% plants survived in each conservation site and the maximum average plant height was recorded as 4.0m after two years of plantation. It will provide a wider buffer for the protection of the forest gene resources. J. Biodivers. Conserv. Bioresour. Manag. 2018, 4(2): 89-98
