摘要:
The extent of damage caused by elephant (Loxodonta africanaBlumenbach) in exotic pine plantations in Zambia was determined by survey. Elephants damaged pine trees by stripping the bark. In commercial plantations the number of injured trees was small, but in seed orchards and seed stands the damage was extensive, and is associated with wide espacement. In 1979, some 1000 pine seed trees were dead or dying following elephant damage which occurred during the last two or three years.Pinus kesiyawas worst affected, butP. oocarpaandP. caribaeaalso proved vulnerable, andP. merkusiiseems least susceptible.
