This Massachusetts Division of Ecological Restoration (DER) study evaluates the effectiveness of dam removal along waterways. Findings show that dam removal is less expensive than repairing and maintaining dams, reduces flood risk to surrounding properties, and creates better stream habitat.
This resource offers an extensive list of studies, papers, and articles on the economic benefits of river conservation, with summaries of their content.
Wetlands filter and clean water, which decreases the costs of drinking water treatment, and they reduce the frequency and intensity of floods. They support the life cycle of 75% of the fish and shellfish commercially harvested in the U.S., and up to 90% of the recreational fish catch. For example, in South Carolina it would require a $5 million treatment plant to remove the pollutants filtered by the Congaree Bottomland Hardwood Swamp.
Study shows that annual sport fishing activity in this Alaska municipality generates more than $63 million in spending on goods and services, accounting for over 900 jobs. Fishing also produces over $6 million in state and local taxes.
The destruction of mangroves has a strong economic impact on local fishing communities and on food production in the region. Mangrove-related fish and crab species account for 32% of the small-scale fisheries landings in the region. The annual economic median value of these fisheries is $37,500 per hectare of mangrove fringe, falling within the higher end of values previously calculated worldwide for all mangrove services together.
Groundbreaking study analyzes the potential of 21 natural solutions—such as growing taller trees, preserving grassland, and improve agricultural practices—to store carbon and reduce greenhouse-gas emissions.
There are 15 state fish hatcheries in Pennsylvania. Owned by the state and operated by the Fish and Boat Commission, these hatcheries are strategically located across the Commonwealth to take advantage of high-quality water supplies and to maximize fish stocking logistics. Pennsylvania's state fish hatcheries are engines for economic development. Eight hatcheries combine to produce some 4 million adult trout annually. Stocked into the waters of the Commonwealth, these trout support fishing activity that generates some $500 million in economic activity each year.
Study estimates that undeveloped floodplains and wetlands along Otter Creek saved Middlebury, Vermont $1.8 billion in flood damage during Tropical Storm Irene and reduced damage by 54–78% across nine other flood events. The annual value of the flood-mitigation provided by the open space is as high as $450,000 per year.
A first-ever analysis released by the Chesapeake Bay Foundation finds that the economic benefits provided by nature in the Chesapeake Bay watershed will total $130 billion annually when the Chesapeake Clean Water Blueprint, the regional plan to restore the Bay, is fully implemented. The Economic Benefits of Cleaning up the Chesapeake also reveals that in Pennsylvania, those annual benefits will approach $40 billion.
This report provides an in-depth look at the declining environmental health of the Jersey shore and an examination of the impact this has on New Jersey’s economy. New Jersey’s tourism, municipal water supplies and coastal fisheries depend on the health of the Jersey Shore. The declining health has caused a 20% decrease in total commercial fishery revenues and the need to install a $5 million desalination plant in Cape May.
Study shows that coastal wetlands reduce the damaging effects of hurricanes on coastal communities, saving lives and minimizing property damage.
This fact sheet on watershed services documents the significance of investing in forest conservation to protect our drinking water supplies. Private landowners are stewards of over 427 million acres of forest land and their management practices play a vital role in ensuring a sustainable supply of ecosystem services for the public.
