Mammals as BioContol Essays -- Environment Farming Agriculture Essays

Mammals as BioContol Biological chasteness is a method of decreasing the nation of pests that compete with vegetation. There be different methods of bio-control. Farmers use parasites, diseases, and predators as forms of bio-control in their fields. Sheep, goats, dotty, cats, and mice are among the different mammals used for pest control. Sheep are used to control silvery-leafed spurge on many rangelands, and bats for controlling insects. We testament demonstrate the benefits and downfalls of sheep and goats controlling unwanted weeds, and how a study has been done to prove that bats chip in made a huge difference in the community of insects that harm agricultural crops. Sheep and goats have both been used to control leafy spurge. Leafy spurge is very unpalatable for most animals, and therefore is barely consumed by sheep and goats. This weed produces a large amount of seeds and reproduces quickly. Since it is a noxious we ed, and isnt profitable for the production of crops, this becomes a problem that needs to be controlled. Sheep and goats will graze leafy spurge to decrease the spread of the plant, but wont completely rid the population. The seeds can live through the digestive process and return to the soil in the form of feces. Not all seeds returned to the install will germinate, but some will. Sheep are more effective than goats only because the seeds can travel through the goats system faster. Since the seeds have the potential to germinate after they have been eaten, the sheep and goats should be kept from areas that are free of leafy spurge for about five days to ensure they wont be spreading it. Studies have also shown that lambs are useful in minimizing... ...Burning on Aristida ramosa and Sheep Productivity in Northern New entropy Wales.
