Human Control on Ecosystems
Physical Control
Confinement of animals & plants
Physical supports given to plants e.g. stakes, pruning, mowing
Killing of animals e.g. hunting
Performing routine operations on animals e.g. dehorning, castration
Removal of plants & animals for consumption e.g. cropping, harvesting
Chemical Control
Poisoning unwanted organisms e.g. fungus, bacteria
Stimulating growth using nutrients
Chemical induced changes to organisms e.g. colourants, hormones
Habitat Control
Modifying soil, earth & rock e.g. ploughing
Provision in certain environments e.g. greenhouses
Introduction & exclusion of fire
Habitat destruction e.g. deforestration
Biological Control
Spread of diseases to unwanted diseases e.g. myxomatosis in rabbits
Introduction of predators and parasites to remove unwanted species e.g. cactoblastis on prickly pear
Introduction of species for human benefit e.g. marram grass for sand dune stabilisation
Genetic Control
Regular importing of organisms with special characteristics
Importing genetic material e.g. artificial insemination
Control on plant & animal breading e.g. hybridisation, selective breeding
Genetic changes to control unwanted species
Behaviour Change
Subjugation e.g. 'breaking' horses
Training animals to respond to stimuli e.g. attack when identifying a sound
Stimulating inherent responses e.g. inducing 'spring' behaviour when removing organisms from the fridge
Water Cycle Control
Supply or removal of water
Weather Modification
