Investigation on relationship between ecological factors and natural distribution and density of Salvia mirzayanii Rech. & Esfand. medicinal species in Hormozgan province

This research was carried out for investigation on relationship between ecological factors and natural distribution and density of Salvia mirzayanii since 2001 for two years. Salvia mirzayanii is one of the important species of Hormozgan Province that is used for diarrhea, stomachache, headache, wound, sugar and high blood cholesterol from ancient times by natives of Hormozgan. In this investigation, distribution map, climate, soil and geologic characters, natural flora of habitats and land uses were provided and also vegetative parameters as height, aerial cover density and aerial cover percentage per hectare were measured. This species located in mountainous region on Miocene limestones and marnes and asmari-jahrom limestones formations from 600–2100 m above sea level. Habitat soil was sandy loam with EC= 0.31-0.71 mm/cm and pH= 8.21–8.46. The minimum and maximum of absolute temperature of habitat were zero and 50 centigrade.
