Item type:Publication, Policy Processes in the Institutionalisation of Private Forestry in the Republic of North Macedonia(MDPI AG, 2022-03-29)<jats:p>As a result of recent political changes in North Macedonia, economic practice in the country has moved away from the communist model that was dominated by state ownership. As a part of this movement, the National Association of Private Forest Owners was founded to support the sustainable management of private forests and as an instrument to help overcome the new challenges faced by this new interest group and government policy in local forestry. Therefore, the aim of this paper is to understand the enabling and constraining aspects of North Macedonian forest policy on the institutionalisation of private forestry. The findings show that some socialist structures and practices related to forest management activities on private forest land still exist. The attempts to strengthen private forestry by introducing more modern forms of institutionalisation can be seen in the country’s Law on Forests amendment from 2011 initiating the denationalisation of forest management activities on private forest land and introducing private licenced bodies for such. With further amendments in 2014, the policy largely returned to how it was when the country was a part of Yugoslavia, influencing the progress of the institutionalisation of private forestry to remain symbolic. Integrating solutions to private forestry problems and concerns into the broader forest policy domain requires a deep understanding of private forestry rational principles and a strong political will to do so. Effective national forest policy coordination is one of the solutions.</jats:p> - Some of the metrics are blocked by yourconsent settings

Item type:Publication, First Report of Verticillium Wilt on Ailanthus altissima (Tree-of-Heaven) in North Macedonia caused by Verticillium dahliae(American Phytopathological Society, 2025-03-17); Voglmayr, HermannTree-of-Heaven, a highly invasive species on all continents except Antarctica, is frequently found on the Balkan Peninsula. In 2019, Ailanthus altissima has been put on the "List of invasive alien species of Union concern"; thus, measures for eradication and control are mandatory in all EU member countries. Verticillium wilt of A. altissima, which has been reported in the USA (Schall and Davis 2009; Kasson et al. 2014; Rebbeck et al. 2013) and in Europe (Maschek and Halmschlager 2016; Moragrega et al. 2021) in the last decade, has already been successfully used for biological control of Ailanthus. In the course of an excursion of the international REUFIS meeting, young symptomatic A. altissima trees, exhibiting severe foliar wilt symptoms, brownish vascular discoloration, dieback, and premature death, were observed at two different sites in the southern part of Skopje, North Macedonia (Kluchka Sonchev: 41.973155N, 21.428846E; Vidikovec (Panorama): 41.977671N, 21.421135E) in June 2024. To identify the causal organism, 50-cm-long branch samples were taken from symptomatic A. altissima and cut into 5-cm pieces, surface sterilized by dipping into 96% ethanol for 1 min, and then breamed. After removing the bark, 23 (Kluchka Sonchev) and 8 (Vidikovec) tissue samples of about 5 mm in length were excised from discolored sapwood and placed onto 2% malt extract agar plates supplemented with 100 mg/l streptomycin sulphate. Plates were incubated at 22°C in the dark for 10 days. Fungal colonies emerged from all plated tissue samples of both sites, all of which were putatively identified as Verticillium dahliae Kleb. based on the abundant formation of microsclerotia and the hyaline, non-septate, cylindrical or ellipsoid conidia developing on verticillate conidiophores. Morphological identification was confirmed by DNA sequencing of two selected isolates (one from each site), using primers coding for ribosomal internal transcribed spacer (ITS1) and elongation factor 1-alpha (TEF) (Inderbitzin et al. 2011) and a BLAST search against the reference sequences of the type strain of V. dahliae PD322 (GenBank Accession No. NR_126124 (ITS) and HQ414624.1 (TEF)) at NCBI NLM, which revealed 100% homology (ITS1: 492 matching base pairs; TEF: 579 matching base pairs) between the type strain and the two North Macedonian isolates. Aligned sequences of both isolates (Vd-NM01, Vd-NM02) were deposited in GenBank (Accession Nos. PQ615325, PQ615358, PQ858706, PQ858707). To confirm pathogenicity, 10 two-year-old potted Ailanthus seedlings were stem-inoculated with a conidial suspension (1 x 107 spores/ml, 1 ml/tree) of V. dahliae isolate Vd-NM01 and 10 with isolate Vd-NM02 on September 12, 2024; 5 seedlings treated with sterile water and 3 untreated seedlings served as controls. Following maintenance in the greenhouse, all V. dahliae-inoculated trees developed wilting symptoms two to three weeks after inoculation and were completely defoliated or showed heavy wilting symptoms on October 31, 2024, whereas all 8 control trees remained asymptomatic or displayed minor wilting symptoms related to autumn senescence. V. dahliae was re-isolated from all treated trees, but no control tree, thus confirming Koch's postulates. Despite of the high disease severity on infected trees, natural V. dahliae infections will not allow efficient control of A. altissima without human intervention on these affected sites in North Macedonia, due to the low disease incidence (<5%) on both sites. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Relationship Between Some Structural Elements of Macedonian Pine (Pinus peuce Gris.) in Different Elevations in National Park Pelister in North Macedonia(Faculty of Forestry, University of Zagreb, 2023-05-24); Nestorovski, Ljupčo<jats:p>The influence of elevation on the forest development and also on more structural elements is evident. The aim of this paper is to research the impact of elevation on the relationship between diameter at breast height (DBH), tree height (H), crown length (L) and stem volume (V). In the area of the Pelister National Park in North Macedonia, 22 experimental plots (EPs) were established in the even-age Pinus peuce Gris. stands with an average age of 90 years. The EPs were of a circular form and covered an area of 500 m2 each; 6 of them were established at 1150 meter above sea level (m asl), 7 at 1350 m asl and 9 at 1550 m asl. DBH, tree height, and crown length of 481 trees were measured in all EPs. The DBH – H model was prepared in accordance with Prodan, as well as nonlinear (polynomial) regression for the relation between DBH and L and nonlinear (power) regression for the relation between DBH and V. The stem volume was calculated with a formula by Parishko for Pinus peuce Gris. The quadratic mean of DBH, average Loray height, average crown ratio, and the density of the stands were also calculated. The relationship between DBH and H, L, and V was examined with Pearson correlation and root mean square deviation (RMSE). The differences between averages of H, L, and V from the EPs were tested with analysis of variance (ANOVA) with an elevation class (1150, 1350 and 1550 m asl) as single factor. The density of stands was 490, 429 and 409 trees per ha on 1150 m, 1350 m and 1550 m asl, respectively. The average DBH was 39.8 cm, 46.5 cm and 45.5 cm, and Loray height was 23.9 m, 24.1 m and 22.6 m at 1150 m, 1350 m and 1550 m asl, respectively. Crown ratio (CR) pointed out different results on the different elevations, with the average value of 40.5%, 43.7%, and 39.3% at 1150 m, 1350 m, and 1550 m asl, respectively. Differences between average structural elements at different elevations can be confirmed with ANOVA with a significance of p<0.05 and F of 3.4 for H, the significance of p<0.05 and F 3.2 for L data and p<0.05 and F of 9.7 for the value of V. In that way, the regression model for H is higher at a lower elevation, the tree has a longer crown length at lower elevation and also has a bigger volume at lower elevation. From the results, it can be concluded that the elevation has an influence on the relationship between DBH on the one hand and H, L and V as structural elements on the other hand. It can be said that at higher elevation trees have a smaller average height, DBH, and volume and have longer crown length than trees at lower elevation.</jats:p> - Some of the metrics are blocked by yourconsent settings
