Abstract
This research was conducted on the Uluyayla Rangeland in Bartın Region. The aim of the study were todetermine botanical composition, canopy coverage, rangeland quality degree and some soil properties such astexture, bulk density, organic matter content, pH and CaCO3 content. In the event that the current grazingmanagement causes degradation in range vegetation of case area, the rehabilitation measures will be proposed tothe preserve their quality. The area is almost 150 ha with an altitude of 1060 m. According to Tornthwaitemethod, climate of the area is humid, mesothermal (B2B1rb4'). A total of 93 plant species was recorded (17grasses, 10 legumes, 66 other species). Some botanical characteristics and quantitative analysis of rangevegetation (frequency, botanical composition, and canopy coverage) were determined by using the transectmethod. Botanical composition was 34.17% grasses, 14.36% legumes and 51.47% other plant families. Therange condition score was determined for each range site using by the range quality degree methods. The rangecondition classes indicated that the range site were in “moderate class”. The degree of range quality, an indirectmeasurement of grazing intensity, was 4.30 in research area. The average soil texture of the rangeland areasclassified, as loam. Soil pH in whole area was slightly acidic. The rangeland soils were characterized by highorganic matter, low electrical conductivity and low lime content.
