These Technical Guidelines are intended to assist those who cherish the valuable service tree genepool and its inheritance, through conserving valuable seed sources or use in practical forestry. The focus is on conserving the genetic diversity of the species at the European scale. The recommendations provided in this module should be regarded as a commonly agreed basis to be complemented and further developed in local, national or regional conditions. The Guidelines are based on the available knowledge of the species and on widely accepted methods for the conservation of forest genetic resources. The Slovenian annex provides brief insight into current status and perspectives of gene conservation and production of forest reproductive material of service tree in Slovenia.

COBISS.SI-ID: 3132326These technical guidelines are intended to assist those who cherish the valuable black alder genepool and its inheritance, through conserving valuable seed sources or use in practical forestry. The focus is on conserving the genetic diversity of the species at the European scale. The recommendations provided in this module should be regarded as a common agreed basis to be complemented and further developed in local, national or regional conditions. The Guidelines are based on available knowledge of the species and on widely accepted methods for the conservation of forest genetic resources. The Slovenian annex provides descriptions of the black, grey and green alder, an overview of their natural distributions in Slovenia; their management, nature conservation and use of forest reproductive material. A special emphasis is on the role of multiple root symbioses of alder with actinomycete nitrogen fixing bacteria in root nodules, and with mycorrhizal fungi, which in combination enable the use of alders for rhizoremediation of contaminated substrates, and of bare, unstable slopes, defficient in nutrients, especially nitrogen.

COBISS.SI-ID: 3288486Planting is the most established and common way of regeneration of oak stands in forestry practices. Problems with planting are high costs, a lot of tendingis needed, high losses are frequent and the final quality may be poor. In this project efficiency of planting in 12 and 11-year-old pole stands have been analysed. Those have been compared with the same age pole stands, which were regenerated naturally. According to the results, the losses did not depend on different year of planting, but they were more likely caused by the site and its specific conditions. Expansion and proliferation of false acacia and clearcuts affected plantation success negatively. Clearcutting caused swamping and overgrowing of the site with weed. Losses of plants from 1998 and 1999 amounted 78 % and 83 %, respectively. Natural regeneration was more successful than planting. Tree density was higher (9 550 trees/ha), with high share of pedunculate oak (75 %) and the quality was better - average hight of branch-clear stem was 4.4 m. Suggestion about the future forestry practice in Slovenia is to introduce new approaches of planting in Slovenia, e.g. partial-surface (cluster) planting. This concept offers costs reduction and a better success. On vulnerable pedunculate oak forest sites it would be better to cut trees progressively than using clearcutting.
