These practices range from choosing a good site with adequate drainage to the having an appropriate tree per acer (TPA).
Trees approaching a diameter of 90 centimetres (3.0 ft) may be used to construct a dam, although the average is 10 to 30 centimetres (3.9 to 11.8 in). Log length depends on the diameter of the tree and the size of the beaver. There are recorded cases of beavers felling trees of 45 metres (148 ft) tall and 115 centimetres (45 in) in diameter.

The beavers are then put into a bunker where they wait until they're released into drought- and fire-prone areas with the hopes that they'll create their own colonies.
Wetlands also aid in water filtration by removing excess nutrients, slowing the water allowing particulates to settle out of the water which can then be absorbed into plant roots. Their vegetation and soil trap sediments and pollutants, while beneficial microbes in the wetland break down harmful substances. In this manner, these invertebrates ...
