How do animals bring about soil erosion?

Answer 1

There has been some total clearing of the rainforest.

There has been some logging.

There are roads put in that:

help weeds to invade,

open up the canopy increasing light that changes what can live there,

open up the canopy causing water loss that changes what can live there,

cause a lot of erosion that damages the fringing reef.

Spread a lot of pollutants

Fed themselves to the crocodiles / got angry and killed the crocodiles

Caused rapid climate change which threatens immediately greater storm damage and then . . . who knows?

Answer 2

People and animals cause erosion simply by moving soil.

Animals might cause erosion by over grazing or burrowing, but humans cause much more through construction, farming, and other large displacements.

Answer 3

Animals can bring about soil erosion in the following ways:

• Stock animals such as sheep and cattle can over-graze an area, leading to plants being completely eaten, roots and all, or their roots exposed to the point where they no longer hold the soil.
• Burrowing animals such as rabbits can cause soil erosion through their digging activities.
• The hooves of large animals such as horses, cattle and camels can impact and weather the ground. the evidence of this can be seen in cattle pads (tracks) winding up grassy slopes, where they follow the same track whenever they return to or leave their home paddocks. These pads are always denuded of any vegetation, and so are more easily subject to weathering.
• Where reforestation attempts are made, some animals may nibble off the tender tops and new shoots of young trees, preventing their growth. This, in turn, prevents the trees putting down strong roots that will help hold the soil in place.

Answer 4

They can create erosion by building bridges.

Answer 5

By digging burrows in the ground. the digging will make rocks and roots break apart and causing soft soil.

Answer 6

They walk over the soil and pack it down.

Answer 7

running around on the dirt.
