Abstract

One of the influential factors to maintain and increase the per capita of green space and to achieve the global standard level is properly management of weeds in the green space. Thus, a study was conducted in District 10 parks of Tehran city in 2014 for evaluating and determining the diversity, density, abundance of weeds in a research grass. Sampling was carried out in the summer season. Then, weeds were identified and counted separately in terms of genus and species by using the systemic W method. Ultimately, frequency, uniformity, and mean density of plants and abundance index were calculated. In total, 17 weed species from 13 plant families were identified at the level of Tehran city. In terms of density of weeds, Rezvan Park with 11.28 plants per square meter and Etemad Park with 9.39 plants per square meter had the highest and lowest weed density, respectively. In this investigation, 17 weed species of 13 plant families were identified. Plant families of Poaceae, Asteraceae, Chenopodiaceae, and Amarantaaceae with 3, 2, 2, and 2 species had the highest species diversity, respectively. In total, they included 52.92% of the total weed species. In terms of life cycle, 7 perennial species (42%) and 10 annual species (58%) were identified in District 10 parks of Tehran city. Among the species identified in this study, 13 species had broad leaves (76%) and 4 species had narrow leaves (24%). In terms of abundance index (AI), weeds of Taraxacum officinale L., Polygonum patulum M. Bieb, and Cynodon dactylon (L.) Pers were identified as the most abundant weeds in Distract 10 in Tehran city, respectively.
