Abstract
Objective: The aimed of this study to provide resources to pasture restoration studies for sustainable pasture areas, to obtain data on the impact of plants in pasture areas and to create suggestions for the management of these impacts.
Materials and Methods: Survey studies were carried out in 2019-2020 to determine plant species in pasture areas within the central district of Düzce province. The studies were carried out at 82 points in 12 areas, taking into account the East, West, North and South directions, not less than 1% of the total pasture area of the city centre district.
Results: As a result of the survey carried out in the pastures in the centre district of Düzce, 133 taxa belonging to 31 families were identified. The families with the most taxa were Asteraceae with 25 taxa, followed by Poaceae (15 taxa) and Fabaceae (11), respectively. Perennial plants (56 taxa) take the first place in the distribution of taxa by life forms, followed by one-year (45) and two-year (7) plants. In addition, 25 taxa have multiple life forms. In pasture areas, Cynodon dactylon (26.6 bitki/m2 - %90.0), Lamium purpureum (22.6 bitki/m2 - % 82.5), Plantago lanceolata (21.8 bitki/m2 - %90.5) and Lolium perenne (21.5 bitki/m2 - % 94.7) were the most common taxa. In addition, it was determined that 72 taxa have in different directions impacts in pasture areas. According to these impacts, 29 taxa is toxic, although they have feed value, 25 taxa are high toxic, 10 taxa have injury + wool quality and 8 taxa have injury + toxic impacts.
Conclusion: The pasture areas of the central district of Düzce province have a rich plant composition. However, a significant number of taxa with different adverse impacts have been identified in each rangeland area. In order to prevent risks arising from anthropogenic factors in pasture areas, it will be beneficial to increase legal regulations and pasture controls, as well as to carry out awareness studies on the impact of plants and potential plant invasions. The data also provides resources for the studies that can be done on pasture restoration in the relevant area.
