Question

15. Dam construction projects cause damage to forest and wetland habitats. When dams interfere with sediment flows and seasonal floods, they also cause erosion in coastal deltas. When coastal delta, forest, and wetland habitats are disrupted, this can have a negative effect on the biodiversity of the area.Which solution would decrease the impact of this construction on biodiversity?Evaluate the native wildlife in the area before dam construction to determine if any species are at risk of extinction from habitat disruption, and create plans to protect these species if necessary.Build roads that lead from the habitats to the dam construction area to provide a path for animal species to migrate into the region.Measure the biodiversity of the native wildlife in the area before the dam construction project to determine whether the coastal delta, forest, and wetland habitats are healthy.Introduce new species to the habitats that are disrupted by the dam construction project to keep competition and resource use high.

Answer 1

Dam construction will greatly affect biodiversity. It decreased the biomass of water fungal. It increased the microorganisms in the soil. To be able to decrease such effect, roads should be constructed that lead from the habitat to the dam construction. Since there will be an effect on the quality of water and soil on the site of the construction, there is a need for the wildlife somewhere to migrate on. This should be done in order for them to survive.
