80% of Australia’s land area is managed by farmers, indigenous communities, and other private land managers. As a result, effectively protecting Australia's environmental resources requires managing environmental assets on private land, and engaging land owners in this effort. Australian dairy farmers have taken the lead in environmental self-assessments and restoration and preservation of the land and water resources.
Efforts have been made in the last several decades to preserve and restore Australian lands by dairy farmers. Efforts have included all but one the following techniques. Identify the technique that does not help with restoration or preservation.
A) Irrigating pasture land during times of water stress and drought.
B) Planting trees, shrubs and grasses to increase river bank stability.
C) Fertilizer use on an as-needed basis to reduce nitrous oxide emissions.
D) Diverting murky run-off from farms into settling ponds to let nature clean it.
