No results found.The relevance of research on biodiversity conservation corresponds to the trends of ideas of the last century, summarized in the Rio Convention (1992) and subsequent international acts. The greatest problem is the preservation of intraspecific diversity. According to the chromosomal inheritance theory of Sutton and Boveri, the number of possible phenotypes of two parents is expressed as 2n,and genotypes as 3n, where n is the haploid number of chromosomes in the parents. In particular, for poplars this is ≈ 500 thousand different descendants, and the number of genotypes can be ≈ 4.6 billion. Taking into account the decoding of genome data, these values can be increased many times. In forest tree breeding researchers try to identify the most useful organisms or their aggregates from the existing varieties. Since its Foundation in 1971 the All-Russian Research Institute of Forest Genetics, Breeding and Biotechnology has been working to create an ex situ field collection fund of practically valuable clones, hybrids and varieties of poplars. The collections were created over the next 50 years, taking into account the recommendations of the field experience methodology. In different regions of the country the collections of hundreds clones and new hybrids in 5 locations; the variety testing sites in 15 locations; and root cutting plantations in 19 locations were created. Totally, 54.04 ha of poplar experimental objects were created in the South-Eastern part of the European territory of Russia. As a result of many years research, new varieties of poplars have been developed for plantation, protective and reclamation afforestation, as well as for landscaping in the forest-steppe and steppe zones of European Russia.

ArticleConditions for successful local collective action in mangrove forest management: Some evidence from the Eastern coastal area of south Sulawesi, Indonesia
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Resource management characterized by Common Pool Resources (CPRs) requires collective action for its sustainable management. CPRs with “rivalry” and “non-excludable” features face overexploitation problems because unlike the nature of pure public goods, the use of CPRs by one user will reduce the chances of other users taking advantage of it. This study aims to analyze the most appropriate local institutions and tenure arrangements for sustainable mangrove management in Eastern coast area of South Sulawesi, Indonesia. Data and information were collected through in-depth interviews involving key informants selected by using snow- ball method and continued by Focus Group Discussion. Design principles for sustainable management of common pool resources from Ostrom has been used in this study as an analytical framework which illustrate the structure of rules established and imposed by the local CPR’s institutions. The findings show that collective action in sustainable mangrove management can be achieved through accepted rules and agreements that are participatory formulated. The agreed norms and rules have enacted as a benchmark for collective action in maintaining mangrove and to enforce sanctions for violators. The success of the community in sustainable mangrove resources management is mainly supported by the existence of several prerequisites that facilitate collective action. It is necessary to strengthen regulations both at the local and higher level through socialization to the community along with the development of incentive and disincentives system.
