Marshes and mangroves as nature-based coastal storm buffers

Tidal marshes and mangroves are increasingly valued for nature-based mitigation of coastal storm impacts, such as flooding and shoreline erosion hazards, which are growing due to global change. As this review highlights, however, hazard mitigation by tidal wetlands is limited to certain conditions, and not all hazards are equally reduced. Tidal wetlands are effective in attenuating short-period st

Sixty years of channel adjustments to dams in the two segments of the Missouri National Recreational River, South Dakota and Nebraska

The Missouri National Recreational River (MNRR) consists of two Missouri River segments managed by the National Park Service on the border of South Dakota and Nebraska. Both river segments are unchannelized and maintain much of their pre-dam channel form, but upstream dams have caused reductions in peak flow magnitudes and sediment supply. The 39-mile segment is located between Fort Randall and Ga

Manatee population traits elucidated through photo-identification

Data on the demography and distribution of wildlife populations are important for informing conservation and management decisions; however, determination of life history traits and population trends often are elusive. All four extant species in the order Sirenia are deemed vulnerable to extinction; therefore, determining the demography and distribution for populations worldwide is crucial. Aerial

Mapping Avian Habitat for the Gulf Coast Joint Venture

The Gulf Coast Joint Venture (GCJV) was established in 1988 as a result of the North American Waterfowl Management Plan, which espouses the restoration of continental waterfowl populations through conservation partnerships in priority habitat regions. Since that time GCJV partners have expanded their mission and purpose to include the provision of habitat to support other priority bird species...

CarpDAT Invasive Carp Data Catalog

Four types of invasive carp fish species are currently found in the United States: black, grass, silver, and bighead carps. These species are fast growing, prolific feeders that out-compete native fish species and drastically alter the natural ecosystems they invade.
