56. Tree diseases determined by the reporting, prognostic and diagnostic service for forests in Slovenia 1982-2012Nikica Ogris, Dušan Jurc, 2013, review article Abstract: The Reporting, Prognostic and Diagnostic (RPD) service for forests is a legal forest protection organization in Slovenia and part of the public forest service. The aim of our study was to analyse RPD reports from 1982 to 2012. We analysed 120 reports that contained 992 records of tree diseases encompassing 189 species and genera. The most frequently recorded were foliage diseases (351 records, 42 species), needle diseases (162 records, 23 species), rots (111 records, 56 species), cankers (73 records, 9 species), and shoot diseases (72 records, 14 species). Ten most frequently recorded species were the following fungi: Erysiphe alphitoides, Lophodermium spp., Cryphonectria parasitica, Rhytisma acerinum, Sawadaea bicornis, Diplodia pinea, Hymenoscyphus pseudoalbidus, Mycosphaerella pini, Blumeriella jaapii, and Cronartium ribicola.

58. Ophiostomatoid fungi (Ascomycota: Ophiostomataceae) associated with bark beetles and their possible economic impact in forests and timber productionAndreja Nève Repe, Maja Jurc, 2010, original scientific article Abstract: Ophiostomatoid fungi are commercially and economically important group of fungi in forestry and timber production. This group is represented by several genera of Ascomycetes with common morphological characteristics, although withdistinct taxonomy and phylogeny. Several genera of ophiostomatoid fungi have been considered synonymous solely based on morphological similarities as a result of an adaptation to insect dispersal. Ophiostomatoid fungi cause considerable economic losses in the forestry and timber production due to sap stain and vascular wilt diseases. The threat of introduced ophiostomatoid fungi is increasing with the global timber trade and loose control measurements. An overview of the taxonomy, ecology, concept of association (mutualism/symbiosis) and the economic importance of ophiostomatoid fungi are provided.

60. Windthrow factors - a case study on PokljukaNikica Ogris, Sašo Džeroski, Maja Jurc, 2004, original scientific article Abstract: This paper presents a case study in windthrow. The case study area was 1.7 ha of two forest gaps on the Pokljuka plateau, Slovenia, where strong wind had blown down 44 trees. An additional 44 standing trees closest to the fallen trees were used as a control group for comparative purposes. The following variables were measured for fallen trees: breast diameter, height, crown diameter and height as well, the number and diameter of roots, the volume of the root system, and root rot. Standing trees were measured for breast diameter, height, crown diameter and height, and the number and diameter of roots. The data were analysed using the machine learning methods in the Weka computer program. The most important factors of windthrow in the case study area were: storm wind (speed above 17 m/s), wet shallow soil, and the edges ofthe forest gaps. The results of the case study show that breast diameter, tree height and the presence of root rot can be classified as windthrow factors.
Keywords: wind, windthrow, root rot, factors of windthrow
