Of the vital rates that determine recruitment, breeding propensity (i.e., the proportion of females that lay at least one egg) and nest success appear to have the greatest influence, but breeding propensity remains poorly studied. The few studies that have been conducted reveal it to be highly variable among years (15–77%), likely in response to environmental conditions (e.g., precipitation and wetland availability), and lower than estimates from other dabbling ducks. Thus, quantifying breeding propensity across the mottled duck range in the WGC and identifying factors responsible for its variation remain high priorities for future investigation. Breeding propensity is also among the most difficult vital rates to...

Coastal zone managers and researchers often require detailed information regarding emergent marsh vegetation types (that is, fresh, intermediate, brackish, and saline) for modeling habitat capacities and needs of marsh dependent taxa (such as waterfowl and alligator). Detailed information on the extent and distribution of emergent marsh vegetation types throughout the northern Gulf of Mexico coast has been historically unavailable. In response, the U.S. Geological Survey, in collaboration with the Gulf Coast Joint Venture, the University of Louisiana at Lafayette, Ducks Unlimited, Inc., and the Texas A&M University-Kingsville, produced a classification of emergent marsh vegetation types from Corpus Christi Bay,...

Habitat loss and degradation due to urban expansion and other human activities have raised concerns for the Western Gulf Coast Mottled Duck population. This species relies on tidal, palustrine, and agricultural wetlands as well as grasslands for all of its life cycle needs. The disappearance of suitable nesting and brood-rearing habitat is believed to be the primary factor associated with long-term population decline of the mottled duck. One of the first science projects initiated by the GCP LCC was development of a spatially-explicit Decision Support Tool (DST) to help guide conservation and management of habitat for breeding Mottled Ducks in coastal Louisiana and Texas. An important next step is evaluating the...
