(Deinen abfälligen Äußerungen gegenüber der Germanischen Wissenschaft (da zähle ich mich in der Tat zu) zum Trotz) FYI:
" Boer goats are hardy, graze a wide spectrum of plants, grasses and shrubs, effectively combating bush encroachment, have low water turnover rates and low internal parasite infestation"

"Goats are often used to clear
weeds in forestry areas. They can also be used to combat bush encroachment,
especially in the Limpopo and Northwest Province."

"Under proper management, goats can improve and maintain grazing land and reduce bush encroachment (biological control) without causing harm to the environment."

"Browsing animals, such as goats, eland, kudu, bushbuck and black rhino, as well as mixed feeders such as elephants, impala and nyala are effective in controlling woody vegetation naturally.
But Frits warns that goats are usually the only browsers that can be found in the required numbers and can be managed effectively to assist with bush encroachment. He adds that overgrazing, particularly the lack of veld rest, weakens grasses."

"Goats browse much more than cattle and mixed grazing is probably less favourable to bush establishment than cattle alone; goats may be used to browse regrowth after fire. Herbicides are used in some commercial systems; they are favoured in South Africa and used to prepare land for over-seeding in the Campos."

"As an aftercare measure, goats can be introduced successfully to utilise and control regrowth as a follow-up to other methods like the application of herbicides, felling/stumping, and controlled or accidental fires."
"However, if seeds from invader species like Acacia mellifera, Dichrostachys cinerea and Prosopis are available in abundance, goats can play a major role in the distribution of seeds and subsequent seedling establishment.As a general rule, goats should be used in combination with cattle. The stocking rate will depend on the amount of bush and regrowth, as well as the grass yield."

"Using goats as a control for resprouting was found to be incredibly successful. After the bushes were initially killed using herbicides and mechanical means, the goats were allowed to graze in the recently cleared area to prevent the spread of any remaining invasive plants as well as any new sprouts."
"Animals, such as goats and cattle, have been used in Namibia in an attempt to control
bush encroachment (MET, 2008). It was found that goats alone decreased the bush by 70.1%,
and cattle alone decreased the bush by 62.8%. However, when goats and cattle are used
together, the quantity of bushes decreased by 77.8%. Since the cattle prefer to eat the
grasses, the goats are forced to eat more bushes due to competition for grasses. An
advantage to using only goats, however, is that grass species increase by 1.95-3.6%."
