Mottled ducks (Anas fulvigula) are non-migratory residents of Gulf Coast marshes and adjacent coastal wetland and prairies, and are split into two genetically and geographically distinct populations. The Western Gulf Coast (WGC) population stretches east from the Laguna Madre, Mexico, to Alabama, while the Florida population is confined to the geographic extent of the state of Florida. The WGC population has been declining for the past 60 years with an accelerated decline over the past two decades. Compounding this decline is a continued gradual change in habitat structure, quality, quantity, and regional availability since the 1930s. The coastal prairies and marshes where mottled ducks reside are disturbance-driven ecosystems in which fire, hurricanes, tidal inundation, grazing, and other factors historically altered this dynamic landscape. In the last few decades, urbanization and human expansion have added additional stressors to landscape changes, that result in lesser quality and quantity of suitable mottled duck habitats through this landscape. To date, little research exists on how fire, either prescribed or wildland, impacts mottled duck habitat use and resource selection. We performed a meta-analysis using location data from five historical mottled duck telemetry data-sets (Rigby 2008, Wehland 2012, Davis 2012, Moon 2014, Bonczek 2022) to analyze mottled duck habitat use, and resource selection during the breeding and brooding season (1 January – 31 July), relative to habitat cover types (i.e. emergent wetland, non-habitat, herbaceous, dry scrub shrub, wet scrub shrub, high marsh, irregularly flooded marsh, and salt pannes/flats), salinity, crop type and extent, biomass, and several fire-related characteristics (e.g., fire frequency, time since last burn, and patchiness of burn) across the Texas and Louisiana coasts from 2006-2020. Using 8,962 locations from these aforementioned studies, in a used vs random framework, we created resource selection models to examine what combinations of habitat cover types, biomass, and fire management metrics influenced mottled duck resource selection over this large spatiotemporal scale. Of 8 candidate models, there was one clear top models based upon AIC model selection criteria. Of these, the top ranked resource selection model included the additive/interactive effects of fire frequency landcover classes (e.g. emergent wetland, non-habitat, herbaceous, dry scrub shrub, wet scrub shrub, high marsh, irregularly flooded marsh, and salt pannes/flats) and vegetative biomass, where neither salinity estimates nor crop presence, extent, or type were included in any top ranking models, indicating that mottled ducks select habitats during the breeding and brood rearing period based upon habitat cover type and fire frequency. Specifically, mottled ducks tended to select emergent wetlands instead of other cover types, with a positive relationship with ‘frequent’ fire (every 1-2 years). Regardless of habitat type, use and selection were driven by a short Fire Return Interval (FRI) of 1-2 years. Conservation and planning efforts for mottled ducks throughout their geographic range in Texas and Louisiana must incorporate protecting and managing emergent marshes, and similar habitat types, with intentional fire management and application at least every 2 years. By providing these matrices of habitat types and condition throughout a heterogeneous landscape, mottled ducks should be presented with adequate habitat to support successful nesting, breeding, and brood rearing activities. Future efforts should focus upon finer-scale nest site selection, nest success, and brood habitat selection in the context of prescribed (and wildland) fires to further advance specific management criteria for this regionally important, yet rapidly declining species.
