Investigation on some Ecological and Morphological Factor of Lagochilus macracanthus Fisch. & C. A. Mey in Yazd Province

Ecological study of behavior as essential elements of their ecosystems and habitat characteristics in order to find appropriate solutions to maintain, revise and revitalize this important part of the renewable natural resources. This present research is about autecology of Lagochilus macracanthus Fisch. & C. A. Mey. Study area is located in near of Nodooshan, Yazd, Iran. Selected sites were within three different elevations; 2300, 2375 and 2450 meters. Sampling was done in a random-systematic way in these elevations. In the site, the studies were climatically characteristic, co-dominant plant, and vegetation variation, physical and chemical analyses of the soil. Results showed that this species is distributed in rangelands with 7.7-7.9 pH, 0.13-0.19 EC ds/m in 2300-2450 meters elevation. According to 10-year statistics, the average rate of rain falls and annual temperature in this habitat is 98.54 millimeters and 14.56 centigrade, respectively. This plant grows as a shrub with the height of 45-60 centimeters. Vegetative growth begins at late-March, flowering occurs in late-May. Seeding happens in mid-July.
