1. Short title This Act may be cited as the Habitat Enhancement Now Act . 2. Grant programs to sustain populations of species of migratory waterfowl (a) Findings Congress finds that— (1) the maintenance of healthy populations of migratory birds in North America is largely dependent on the protection, restoration, and management of wetland ecosystems and other habitats in Canada, as well as in the United States and Mexico, as identified in the Implementation Plans of Joint Ventures authorized under the North American Waterfowl Management Plan; (2) duck populations in North America are being threatened by the loss in the quantity and quality of breeding habitat, which leads to declining nest success; (3) low nest success has been widely documented to be the key annual driver in duck populations; (4) additional tools can be employed to increase nest success to complement the private, State, and Federal habitat conservation programs and efforts in order to sustain healthy waterfowl populations; (5) relatively modest investments in management can make meaningful impacts towards supplementing waterfowl production in areas where waterfowl production outcomes have not been fully met; (6) numerous studies have made it clear that nesting structures, in particular hen houses , are the most efficient and cost-effective tool for increasing nest success
