Vascular flora of a part of the planned Hrvatsko zagorje Regional park (northwestern Croatia)

Abstract

The wild vascular flora of the area in the northwestern part of Croatia-Hrvatsko zagorje (near the settlements of Cerje Jesenjsko, Šaša, Pašnik, Vrbno and Ježovec, along with the related hamlets) was explored during the vegetation season of 2011. So far, no floristic data have been recorded for this area, planned to be a part of the future Hrvatsko zagorje Regional Park. On the area of about 4 km 2 , 389 vascular plant species (which belong to 77 families) were noticed. The most abundant families are Fabaceae (9.3%), Poaceae (7.7%), Asteraceae (7.5%), Lamiaceae (6.2%) and Rosaceae (5.1%). The spectrum of life forms indicates the dominance of hemicryptophytes (50.4%), and the most prominent chorological type is Eurasian (55.0%). The share of urbanophobic and invasive taxa as well as the values of indicators of anthropogenic changes in the researched flora indicate that the investigated area shows semi-natural character, with weak to moderate anthropogenic pressure. Although the share of endemic, endangered and protected taxa is low, the diversity of other native plants justifies protection of the researched area at the level of a regional park.

Vascular flora of Tuškanac Forest Park (Zagreb, Croatia)

“…In terms of percentages, urbanophobic plants (45.3%) significantly exceed the urbanophilic (8.7%), meaning that taxa that most often grow in natural habitats are more than five times as common in Tuškanac than plants that are often present in human-impacted or extensively managed vegetation. Although these values can be used as a simplified hemeroby index (Landolt et al, 2010) this is not often the case in analysis of Croatian flora, making it possible to compare our results only with provincial areas outside of Zagreb (Hruševar et al, 2018). The flora of Tuškanac shows a greater tendency to be "close to nature" vegetation than seminatural area of the planned Hrvatsko zagorje Regional Park (Hruševar et al, 2018), which additionally supports values given by IA analysis.…”

“…2) and its comparison with other study sites (Alegro et al, 2013, Hruševar et al, 2018 indicate much lower IA values for Tuškanac than are calculated for other areas of continental Croatia. An exception is observed in the Indicator of modernisation (IM) with a higher value than calculated for the seminatural area of Hrvatsko zagorje (Hruševar et al, 2018) and Indicator of fluctuation changes (IF), with a value higher than found in other study sites of Central Croatia (Alegro et al, 2013, Hruševar et al, 2018. The former is due the relatively high share of neophytes among the naturalised alien taxa, and the latter is due to the relatively high share of diaphytes in analysed flora.…”

Landolt Indicator Values in Modern Research: A Review

“…Four studies were carried out in both Germany and France. Croatian scientists used the Landolt indicator values in only two studies [38,39]. Single studies cover plant communities of Georgia, Slovakia, Hungary, Bosnia and Herzegovina and the Czech Republic [38,40].…”

Raznolikost biljnih svojti na južnim padinama Ivanščice pored grada Zlatara

“…Različite vrste iz porodice Lamiaceae zauzimaju različite ekološke niše, a različita staništa očigledno povećavaju njihovu brojnost. S druge strane, veća brojnost vrsta iz porodice Rosaceae vjerojatno je povezana s antropogenim utjecajem jer neke od njih često "pobjegnu" iz uzgoja kao primjerice vrste roda Prunus (Hruševar et al, 2018).…”
