With an ever-growing global demand for food, the increased livestock pressures on natural habitats has become particularly damaging. Cattle grazing in traditional forest management systems is practiced in many parts of the world where conifers are a natural forest component.
Negative effects on the forests include selective browsing, soil erosion, depletion of nutrients and compaction of the topsoil. Forest grazing frequently causes slow or no regeneration, poor forest conditions and, in extreme cases, potential ecological disasters. With their ability to climb through trees, goats have a particularly damaging effect on conifers; not only do they browse the foliage but they also strip off the bark. In Mediterranean areas forest restoration of former grazed areas is somewhat complicated in that the ecologist is often faced with the dilema of having to control the biuld up of combustible materials which can become a severe fire risk.
There are 146 taxa in the category – Agriculture and Forestry, Livestock farming/grazing:
Abies delavayi subsp. fansipanensis
This subspecies, described in 1997, is restricted to a single mountain in Northern Việt Nam. The main threats are its small population size and restricted distribution which make it potentially susceptible to stochastic events. … Read full species entry >
