Offered Papers Theme A: Efficient Production from Grassland

Description

Grazing shapes the botanical composition of vegetation at the landscape level (Oksanen et al., 1995). Sheep seek spatially scattered plants of nearly constant and high nutritional value. There is strong interaction between the grazing behaviour of the sheep and the structure of the plant community that it grazes (Squires, 1981). This paper examines the situation in a grassland vegetation grazed by free-ranging sheep in a semi arid region of North Eastern Iran.

The Impact of Continuous Grazing by Free Ranging Sheep on the Structure and Botanical Composition of Grassland as Determined by Multivariate Analysis

Grazing shapes the botanical composition of vegetation at the landscape level (Oksanen et al., 1995). Sheep seek spatially scattered plants of nearly constant and high nutritional value. There is strong interaction between the grazing behaviour of the sheep and the structure of the plant community that it grazes (Squires, 1981). This paper examines the situation in a grassland vegetation grazed by free-ranging sheep in a semi arid region of North Eastern Iran.
