The species of Toothbrushe (Salvadora persica L.) is one of the most valuable forests tree in the southern part of the Iran Which has very scattered and limited habitats from Bandar Abbas to Balochistan. This plant has different Pharmaceutical and Non-Pharmaceutical applications. This research was investigated to evaluate some individual ecological characteristics of this species in Chabahar province in three locations of Ramin, Nobandian and Negor in the province Sistan and Balochistan at 2017. To design a distribution map and also to study the features of the Geological vegetative area have used from 1:10000 maps of Geology organization. To determine the soil characteristics (acidity, Conductivity Electric, Lime, Sodium, Calcium, Magnesium, Potassium, Phosphorus, Nitrogen, Organic matter, Clay, Silt, Sand) in the habitats, the desired profile was digested and sampled. To record the qualitative and quantitative characteristics of the species, first in each habitat, 3 key areas were identified. Then within each region, a Transect was selected and the forestry features of trees such as Collar diameter, Diameter of breast, Trunk length, Crown cover, Height and the and distance between trees were measured. In order to Data analysis between regions difference and SPSS software used and mean comparisons were performed by Duncan test. During the research some Phonological stages such as Leaf emergence, Flower emergence, Full flowering, Emergence of fruit, Fruit arrival, Seedlings, and Deformities were recorded. The results of this study showed that between all characters of Toothbrush (diameter of collar, diameter of breast, trunk length, crown cover, tree height and distance between tree), the density per hectare and height from sea level were Significated. The density per hectare in the Negor region with the number of 19 per ha was greater than Ramin and Novbandian. In terms of altitude above sea level, the highest elevation belongs to the Ramin region with 31 meters and the lowest elevation is from the Nobandian region with 17 meters. Among the soil parameters only Soil sodium factor was significant and other soil parameters were not significant. The highest amount of sodium (5.27 ppm) belonged to Negor and its lowest value (3.74 ppm) was for the Novbandian. In terms of Electrical conductivity, Phosphorus, Potassium, Magnesium and Organic matter belonged to Negor region had the highest amount, but there was no significant with other areas. In terms of Soil depths, Soil pH and Potassium had a significant difference with other parameters, and the highest pH (8.402) belong to depth 60-90 and lowest (8.216) was belong to depth 30-60. The highest Potassium (116.6 mg/kg) belong to depth 30and lowest (80.72 mg/kg ) was belong to depth 60-90. In relation to phenology of this plant, it was observed two stages, and the best seed harvesting season was from May to July. The emergence of leaves began late of November and eventually the oval leaves of the second half of the month began to grow.
