Plant diversity of front gardens in city district Trnje

Područje gradske četvrti Trnje nastanjeno je još od rimskih vremena, a najveći porast stanovništva bilježi početkom 20. stoljeća u vrijeme industrijalizacije kad se iz ruralnog prostora pretvara u radničku četvrt ilegalno podignutih objekata loše kvalitete. Zelenilo u gradovima ima veliku važnost za biološku raznolikost, a odabir biljnih vrsta i njihovo održavanje usklađeno je s klimom i reljefom određenog područja; te s potrebama, vremenom i financijskim mogućnostima vlasnika vrtova. Premda uređenjem predvrtova znatno utječu na sliku grada, ne postoje nikakvi propisi kojima bi se odredio njihov izgled. Cilj ovog rada bio je pomoću Geoportala izmjeriti površine parcela i postotak izgrađenosti i popločanosti, inventarizirati biljne vrste koje se nalaze u predvrtovima gradske četvrti Trnje, te odrediti njihovu taksonomsku pripadnost, razvrstati biljne vrste prema prisutnosti u zonama, ocijeniti uređenost vrtova, te procijeniti prisutnost vrtnih elemenata. Tijekom mjeseca ožujka do kraja lipnja 2019. provedeno je terensko istraživanje na 34 predvrta na području gradske četvrti Trnje. Ulice koje su bile obuhvaćene istraživanjem: Križna cesta, Drinska ulica i Ulica II. Trnjanski nasip. Analizom je otkriveno kako je najveći vrt bio u Drinskoj ulici veličine 656,83 m2, a najmanji u Križnoj cesti veličine 4,89 m2. Najveći postotak pokrivenosti bio je u Križnoj cesti u iznosu od 63%. Najzastupljenija zona u kojoj su smještene biljne vrste je središnja zona. Najzastupljenija vrsta je Rosa hybrida L. Najčešći tip ograde u svim istraživanim vrtovima je metalni, a nalazi se u 30 predvrtova, od ostalih vrtnih elemenata prisutne su bile kante za otpad, skulpture te posude za cvijeće.The area of the city district Trnje has been inhabited since Roman times, and the largest increase in population was recorded at the beginning of the 20th century at the time of industrialization when it was transformed from a rural into a working district of illegally erected buildings. Greenery in cities is of great importance for biodiversity, and the selection of plant species and their maintenance is in line with the climate and relief of a particular area; and with the needs, time, and financial capabilities of garden owners. Although landscaping significantly affects the image of the city, there are no regulations to determine their appearance. The aim of this work was to use Geoportal to measure plot areas, their percentage of development and paving, create inventory of plant species found in the front gardens of the city district of Trnje, determine their taxonimic affiliation, classify plant species according to their presence in the zones, evaluate the arrangement of gardens, and assess the presence of garden elements. During the month of March to the end of June 2019, a field research was conducted on 34 front gardens in the area of the city district of Trnje. Streets covered by the survery: Križna cesta, Drinska ulica and Ulica II. Trnjanski nasip. The analysis revealed that the largest garden was at Drinska ulica with size of 656,83 m2, and the smallest was at Križna cesta with size of 4,89 m2. The highest percentage of coverage was at Križna cesta in the amount of 63%. The most common zone in which plant species are located is the central zone. The most common species is Rosa hybrida L. The most common type of fence in all surveyed gardens is metal, and it is located in 30 front gardens, among other gardenelements there were waste bins, sculptures and flower pots
