Abstract

Z diplomsko nalogo so želeli ugotoviti stanje dreves v mestu Idrija - popisali so urbano drevje na javnih površinah mesta Idrija, ugotovili njihovo število, vrstno sestavo, premer, višino, starost, prostor za korenine in krošnjo, stanje, poškodovanost ter predvideli ukrepe in stroške za izvedbo del. Drugi del naloge je bil namenjen izdelavi registra in katastra popisanih dreves. Vsakemu drevesu so določili zaporedno številko s pripadajočimi popisnimi parametri. Skupno so popisali 1358 dreves, od tega 21,8 % iglavcev in 78,2 % listavcev. Določili so 47 rodov in 70 vrst. Ugotovili so, da med rodovi prevladujejo lipe (Tilia), javorji (Acer) in smreke (Picea). Največji delež (25 %) zavzemajo drevesa, ki imajo prsni premer pod 10 cm. Glede na višino pade največ dreves v višinski razred od 11 do 15 m, kar predstavlja 26,9 % vseh dreves. Po starosti prevladujejo srednje stara drevesa s 37,5 %. Zdravih dreves je 54,7 %, lažje poškodovanih 30,3 %, močneje poškodovanih dreves je 14,6 %, hirajočih in odmrlih dreves pa manj kot 1 % osebkov. Ukrepe so določili 448 drevesom, za katere bi stroški izvedbe del znašali 47.437,63 eurov. Na podlagi primerjave s Čibejevim popisom leta 2000 so ugotovili, da jeprišlo do razlik v številu dreves in vrstni sestavi, kar je lahko posledica nekoliko različnega območja popisa, napak pri popisovanju in/ali sprememb (poseki/zasaditve) na območju mesta Idrija.

Secondary title:	Updating Idrija tree cadastre
Secondary abstract:	The aim of this graduation thesis was to list individual urban trees in publicareas of Idrija, define their number, species structure, diameter, height, age, roots and crown space, state, damage, and to determine measures to be taken along with the costs of their realization. The second part of the thesis includes register and cadastre of inventoried trees. All trees were assigned successive numbers and appropriate inventory parameters. In total, 1,358 trees have been listed - 21.8% conifers and 78.2% deciduous trees. 47 different genera and 70 species were defined. Predominating genera are lime trees (Tilia), maple trees (Acer) and pine trees (Picea). Most of the trees belong to the group of subjects with diameter that does not exceed 10 cm. Moreover, regarding height, the majority of trees belong to the group of 11 to 15 m tall subjects (26.9%), whereas regarding age, most trees can be assigned to the group of medium age trees (37.5%). It was established that 54.7 % of all trees are healthy, 30.3% are mildly damaged, 14.6% are heavily damaged, and there are less than 1% of dying or withered subjects. Appropriatemeasures have been assigned to 448 trees, the costs of all works would reach 47,437.63 euro. We compared our research to Čibej's inventory (2000), and found out that there are differences in tree number and species structure, which could be the result of slightly different inventory area, mistakes that were made during inventory taking, and/or various alterations (felling/planting) in the town of Idrija.
