“…The excess vegetation and litter made for super-heated fires when they did occur, damaging forest soils and even fire tolerant vegetation (Hodges 1995;Rauscher and Johnson, 2004). Upstream urban and agricultural water demand and climate change have combined to limit freshwater availability in the Apalachicola Region (Light et al, 1995;Leitman et al, 2016;Aavudai et al, 2018). Light et al (1995) estimates that there is approximately a 20 percent decline in discharge at low flow coming down to the Apalachicola River from upstream basins over the last 50 years.…”

Abstract. With a burgeoning world population that is expected to reach 10 billion by 2050, 30 % more than today, there is an urgent need to harness available water resources to support regions across the world. This study introduces a new method to identify, prioritize, and select areas for pine basal area reduction to maximize water yields in pine forests along the Northern Gulf of Mexico, USA. The method, demonstrated in the Apalachicola Region of Northwest Florida, an area covered by dense vegetation and pine plantation forests, has experienced freshwater loss due to increased upstream water demand, climate change, and past forest management practices. Potential initial water-yield gains were: 1) 469 m3 d−1 if all pine basal areas were reduced from current to a maximum of 18 m2 ha−1, and 53,400 m3 d−1 if pine basal areas were reduced from current to a maximum of 7 m2 ha−1 for the Apalachicola Region. The method identifies watersheds mainly along the Apalachicola and other rivers and near the Gulf coast that have the greatest potential to increase water yields. Increasing forest water yields translates to increased freshwater availability and improved forest and soil health, water quality, and ecosystem function, services, and resilience, as well as socioeconomic outcomes for communities and people who rely on ecotourism and fisheries for their livelihoods. This method will empower forest managers to focus scarce resources in targeted areas to maximize water-resource benefits per resource investment. Although demonstrated in the Apalachicola Region, the method is easily transferable throughout other pine forests of the Northern Gulf Coast Region. This scientifically sound method is repeatable, scalable, and easily upgraded and adapted as newer, higher resolution datasets become available and relationships between forest metrics, evapotranspiration, and water yields are improved.

The Apalachicola-Chattahoochee-Flint (ACF) River basin is an important ecological and economic component of a three-state region (Florida, Alabama and Georgia) in the southeastern U.S. Along the Apalachicola River in northwest Florida, the duration of floodplain inundation has decreased as a result of declining river levels. Spring and summer flows have diminished in volume because of water use, storage and evaporation in reservoirs, and other anthropogenic and climatic changes in the basin upstream. Channel erosion from dam construction and navigation improvements also caused river levels to decline in an earlier period. In this paper, we document trends in floodplain forest tree species composition for the interval spanning these influences. Historic tree inventories from the 1970s were compared to present-day forests through non-metric multidimensional scaling, indicator species analysis (ISA) and outlier detection. Forests are compositionally drier today than in the 1970s. Overstory to understory compositional differences within habitats (levees, high/low bottomland forest and backswamps) are as large as the species contrasts between habitats. Present-day forests are also compositionally noisier with fewer indicator species. The largest individual declines in species density and dominance were in backswamps, particularly for Fraxinus caroliniana Nyssa ogeche and Nyssa aquatica. We discuss how contrasts in the compositional change signal for levee and backswamp landform habitats reflect a complex biogeomorphic response to fluctuating river flows for alluvial rivers in humid climates.

The term forested wetland covers a variety of forest types including mangroves, cypress/tupelo swamps, bottomland hardwoods, pocosins and Carolina bays, flatwoods, and mountain fens. These forests are dominated by woody species that have morphological features, physiological adaptations, and/or reproductive strategies enabling them to achieve maturity and reproduce in an environment where the soils within the rooting zone may be inundated or saturated for various periods during the growing season. Although alluvial floodplains occur along most streams of the United States, they are most extensive in the Atlantic Coastal Plain, Gulf Coastal Plain, and Mississippi Alluvial Plain. Only about half of the original floodplain forests remained by the 1930s, and conversion to agriculture continued at an accelerated pace during the 1960s and 1970s. The purpose of this bibliography is to provide a detailed listing of references for students and researchers of the varied studies conducted in these forest types.
