Abstract

Tuškanac Forest Park has been floristically studied over the past 15 years, but most extensively and systematically during the year 2021. Tuškanac Forest Park is a natural treasure in the center of Zagreb City. This oblong 150-year-old stand of oak, common beech, and hornbeam is a natural extension of the vegetation of Mount Medvednica and descends almost to Zagreb's main street (Ilica). A total of 173 vascular plant taxa were recorded (62 families and 131 genera). The largest part of the flora consists of Angiospermae (163 taxa; 94.2 %), followed by Monilophyta (6 taxa; 3.5%) and Gymnospermae (4 taxa; 2.3%). Rosaceae is the richest family with 14 taxa (8.1%), followed by Asteraceae sensu lato (13 taxa; 7.5%), Poaceae (11 taxa; 6.4%), Lamiaceae (9 taxa; 5.2%) and Fabaceae (8 taxa; 4.6%). The highest percentage of recorded plants are hemicryptophytes (41.0%) and phanerophytes (27.7%). The analysis of chorotypes shows that the Eurasian floral elements dominate (50.9%), followed by European (18.5%) and Mediterranean elements (8.1%). Urbanophobic (45.3%) significantly outnumber urbanophilic taxa (8.7%). A “close to nature“ environmental condition is additionally confirmed by the low values calculated for indicators of anthropogenisation and by the low share of alien flora (27 taxa; 15.6%). The following invasive alien taxa grow in the study site: Ailanthus altissima, Duchesnea indica, Erigeron annuus, Parthenocissus quinquefolia, Phytolacca americana, Robinia pseudoacacia and Veronica persica. According to IUCN categories, only two taxa belong to threatened categories: Taxus baccata and Lilium martagon are vulnerable (VU) and both taxa are strictly protected in Croatia.

Tuškanac森林公园(萨格勒布，克罗地亚)的维管植物区系

Tuškanac森林公园在过去15年中进行了植物区系研究，但在2021年进行了最广泛和系统的研究。Tuškanac森林公园是萨格勒布市中心的一处天然宝藏。这片有150年历史的长方形橡树、普通山毛榉和角木林是梅德维尼察山植被的自然延伸，几乎一直延伸到萨格勒布的主要街道（伊利卡）。共记录了173个维管植物分类群（62科131属）。植物群中最大的部分由被子植物科（163个分类群；94.2%）组成，其次是Monilophyta（6个分类群，3.5%）和Gymnospermae（4个分类群：2.3%）。Rosaceae是最丰富的科，有14个分类群（8.1%），其次是Asteraceae senso-lato（13个分类群），7.5%，Lamiaceae（9个分类群；5.2%）和Fabeae（8个分类群，4.6%）。记录的植物百分比最高的是半隐生植物（41.0%）和显生植物（27.7%）。合唱类型分析表明，欧亚花元素占主导地位（50.9%），其次是欧洲元素（18.5%）和地中海元素（8.1%）。城市恐惧症（45.3%）的数量明显超过城市嗜热分类群（8.7%）。人类化指标计算的低值和外来植物群的低份额（27个分类群；15.6%）进一步证实了“接近自然”的环境条件以下入侵外来类群生长在研究地点：臭椿、印度杜香、灯盏花、西洋爬山虎、美洲商陆、刺槐和波斯Veronica persica。根据国际自然保护联盟的分类，只有两个分类群属于受威胁的分类群：红豆杉和马齿百合是脆弱的（VU），这两个分类组在克罗地亚都受到严格保护。
