Structure, development and growth of selection forests at the Granata research site
Matej Reščič, Andrej Bončina, 2007

Povzetek: The Granata research site was established for the study of structure, growth and regeneration of silver fir-European beech single stem selection forest. Three phytocoenological relevés were carried out, all trees ?5 cm diameter at breast height (d.b.h.) were measured by full callipering, tree growth was analysed for sample trees, regeneration of tree species was registered on 63 sampling plots. In addition, historical data from past forest inventories werestudied. In the period from 1952 to 2003, the share of silver fir has decreased from 86% to 26%, the share of Norway spruce increased significantly,whereas the share of beech and sycamore has slightly increased. The current growing stock amounts to 350 m3 ha-1, with large-size diameter trees (d.b.h. ?50 cm) representing 51% of total growing stock. The site is divided into 16 stand patches with significant differences in tree species composition and diameter distribution. Regeneration is sufficient with silver fir prevailing in total number of seedlings (42%). 23% of all seedlings are damaged as a result of game browsing.

Možnosti zaznavanja drevesnih vrst v okviru Monitoringa gozdov in gozdnih ekosistemov
Mitja Skudnik, Robert Brus, Anže Martin Pintar, 2020

Povzetek: Analizirali smo možnosti zaznavanja drevesnih vrst v okviru Monitoringa gozdov in gozdnih ekosistemov (MGGE) s poudarkom na manjšinskih in tujerodnih drevesnih vrstah ter možnosti zaznavanja razlik v pestrosti drevesnih vrst med posameznimi ekološkimi regijami. Zaznavanje minoritetnih in tujerodnih drevesnih vrst bi lahko izboljšali z obsežnejšim šifrantom drevesnih vrst, katerega dopolnitve smo predlagali. Take drevesne vrste bi zajeli z večjo verjetnostjo pri gostejši vzorčni mreži od obstoječe (4 km % 4 km). Opozorili smo tudi na pomen pravilne determinacije drevesne vrste na vzorčni ploskvi. V okviru MGGE smo ugotovili razlike v pestrosti drevesnih vrst med ekološkimi regijami; kot najpestrejša se je pokazala submediteranska ekološka regija.

Using citizen science to monitor the spread of tree pests and diseases : outcomes of two projects in Slovenia and the UK
Peter Crow, Ana Pérez-Sierra, Andreja Kavčič, Kate Lewthwaite, Marija Kolšek, Nikica Ogris, Barbara Piškur, Jana Kus Veenvliet, Simon Zidar, Suzanne Sancisi-Frey, Maarten De Groot, 2020

Povzetek: The trees and forests of Europe are increasingly under threat from new pests and diseases that have originated in other parts of the world. Early detection of alien species when they first appear in European countries allows rapid response and offers the best chance to mitigate against their establishment and spread. Citizen science initiatives such as LIFE ARTEMIS in Slovenia, and Observatree in the UK, provide members of the public with the necessary training and educational resource to identify these tree pests and diseases and report them to the appropriate authorities, thereby increasing the level of surveillance and the capacity of the early warning system. This paper summarises some of the outcomes of these two projects and how they have both become integral parts of the official forest and tree health monitoring systems within their respective countries of Slovenia and the United Kingdom.
