Nanorana parkeri is endemic and widespread in the Qinghai-Tibet Plateau. Oviposition sites selection by N.parkeri was studied in four marshlands in Sejila Mountain, Tibet, during the breeding period in 2011 and 2012. Habitats were surveyed with respect to oviposition (n=37) and random (n=37) sites by measuring 10 factors that might influence the choice of an oviposition site. There were significant differences in the substrate, pH value, water temperature, water depth, vegetation coverage, and fish present between oviposition sites and random sites. Logistic regression analysis indicated that substrate and water pH were the most important factors influencing the choice of female N.parkeri. It is suggested that protecting water bodies with mud substrate and water pH value close to 7 in the marshes is important to the conservation of N.parkeri.
