Autecology of Ferula ovina Boiss in Kerman Province

Ecological study of Ferula ovina characteristics were carried out to find the applicable information in rangeland improvement and development programs. Habitat map was firstly provided by vegetation map and field visiting. Three different stations including Sirch, Modym and Hatkan were selected in these habitats and sampling was done by random-systematic method in every station with 30 plots (4 m²) along transect. In this study, the ecological characteristics (climatic, topographic, edaphic), canopy cover, density, frequency were investigated. Root system, phenology, preference value of the plant and pests were measured. The results showed that habitat elevation for this species was 2600 to 3200 meters above sea level and slopes 30-60%. Besides, average annual precipitation of the habitats was around 130 mm while mean annual temperature ranged between 10 to 16 ºC. The sandy-loamy texture was preferable to this plant. Electrical conductivity of soil and pH were 0.38-0.49 ds/m and 8.0-8.2, respectively. The percent canopy cover, frequency, and density were 9.9%, 93% and 4300 plants per hectare, respectively. Its root system included a main root and a few distributed roots. Stages of plant growth began late March and continued to August. Vegetative growth of plants started from midMarch. Flowering stage of the F. ovina started from the second half of April. This plant can be propagated only by seed with the best seed planting depth of 1 cm. Sheep and goats eat these flowers and leaves. The preference value of F. ovina was 59% higher than other species. Local farmers use this plant for winter forage.
