Abstract:

Bituminaria bituminosa (L.) Stirton is an hemicryptophyte Mediterranean legume characterized by secondary compounds in its mature leaves and by resistance to heavy grazing. Its growing season extends from before the onset of the rains to the end of the spring, attaining primary production double to that of the common herbaceous species. In winter and early spring, when more palatable species are available to the cattle, it is grazed only under heavy stocking rates. Cattle start grazing it under moderate grazing pressures only in mid-spring, when the principal grasses become less palatable. In late spring, when the herbaceous species dry up, B. bituminosa becomes the only species with green leaves and cattle graze the whole plant intensively. B. biturninosa response to grazing was studied in a long-term grazing experiment in a Mediterranean herbaceous community from 1974 to 1990. Results showed that B. bituminosa cover significantly increased with intensity of grazing in both deferment and continuous grazing regimes. Our observations question one of the principles of range management, that perennial herbaceous plants, and legume species in particular, are most sensitive to grazing. This principle assumes that a perennial herbaceous legume shrub under long-term, continuous heavy grazing will be completely depleted. We suggest a model explaining resistance to grazing that involve release from competition with more palatable neighboring herbaceous vegetation and prevention of grazing at the start of the green season via secondary compounds.
