What are major threats to wetlands?

Some of the main activities that can negatively impact wetlands include: Dredging, draining, and/or filling wetland areas for conversion to agricultural, industrial or residential lands. Population growth and urban development. Sand and gravel mining and mineral extraction activities.

What causes wetland loss?

Human activities cause wetland degradation and loss by changing water quality, quantity, and flow rates; increasing pollutant inputs; and changing species composition as a result of disturbance and the introduction of nonnative species.

What does it mean to mitigate wetlands?

What Is Mitigation? Mitigation, a term that frequently occurs in discussions of restoration, “refers to the restoration, creation, or enhancement of wetlands to compensate for permitted wetland losses” (Lewis, 1989). This strategy should result in “no net loss” of wetlands.

What is the function of wetland mitigation banks?

Wetland mitigation banking is the restoration, creation or enhancement of wetlands for the purpose of compensating for unavoidable impacts to wetlands at another location. Wetland mitigation banking is commonly used to compensate for wetland impacts from development, but it also used for impacts from agriculture.

What is a mitigation area?

Mitigation area means any area or areas within the Conserved Lands designated as provided in the Ranch Agreement to satisfy a condition or requirement of any Project Approval (or any similar approval relating to a Potential Project) or required in connection with the Reserved Rights for Mitigation purposes.

How do wetlands credits work?

A wetland or stream mitigation credit is a unit of trade used to offset ecological losses that occur in waters of the U.S., which are regulated by the USACE and USEPA. Wetland and stream credits allow a client to satisfy their environmental mitigation permit needs prior to impacting wetlands or waters.

How do conservation banks work?

Conservation banks are permanently protected lands that contain natural resource values. In exchange for permanently protecting the land and managing it for these species, the U.S. Fish and Wildlife Service (FWS) approves a specifed number of habitat or species credits that bank owners may sell.

How are wetlands restored?

Generally marshes or swamps, with seasonal or permanent water, are most often restored. The simplest restoration, a “tile break,” involves removing a section of underground agricultural tile that is draining a wetland basin.

What is happening to our wetlands?

The world’s remaining wetlands are under threat due to water drainage, pollution, unsustainable use, invasive species, disrupted flows from dams and sediment dumping from deforestation and soil erosion upstream. Wetlands are critical to human and planet life.
