How has cattle farming damaged watersheds and harmed the environment?

Negative impacts of Cattle Farming: Cattle farming (aka “ranching”) can have negative impacts on watersheds and the environment in Hawaii and other areas. Cattle grazing can lead to soil erosion, which can contribute to the sedimentation of streams and rivers and negatively impact water quality. Cattle manure and urine can also contribute to water pollution, as these substances can contain nutrients such as nitrogen and phosphorus that can stimulate the growth of algae and other aquatic plants, leading to eutrophication and other problems.

Cattle grazing in Hawaii has been shown to have negative impacts on forests and watersheds. Heavy browsing by feral cattle and pigs severely limits the regeneration of native tree species in the Hawaiian forest. This limits the ability of these forests to provide ecosystem services such as erosion control, nutrient cycling, and habitat for native wildlife.

Feral cattle and pigs in Hawaii can have significant impacts on stream ecosystems by trampling stream banks, altering water flow patterns, and spreading invasive plant species. This can lead to increased sedimentation, decreased water clarity, and changes in the composition of aquatic plant and animal communities. Cattle grazing can also harm stream ecosystems by increasing sediment runoff, altering water chemistry, and reducing the cover of native vegetation along the stream banks, which can lead to the loss of fish and other aquatic life.

Wild cattle, also known as feral cattle, have been shown to have negative impacts on the forests and ecosystems on Maui.

In East Maui, feral cattle have a significant negative impact on the native forest birds by overgrazing and trampling on the native vegetation, which reduces the availability of food and nesting habitat for these birds. This can lead to declines in the populations of native forest birds.
