“…Rooting also affects microtopographic variation and soil moisture characteristics because soil is frequently mounded up in some areas while depressions are created in other areas. Variability in microtopography and soil-moisture characteristics influence plant community structure (Beatty 1984, Winchester et al 1985, Titus 1990, Smith and Capelle 1992 and contributed to increased microhabitat diversity in our hogrooted plots. Hog roofing also decreases plant cover and breaks up dense mats of dead vegetation, thereby decrea~ing potential competition and increasing light penetration to the soil surface, which can trigger seed germination (Merendino et al 1990).…”

Abstract:We evaluated effects of rooting by feral hogs (Sus scrofa) on total emergent vegetation cover, vegetation species richness, and diversity of plant-defined microhabitat types in an impounded floodplain marsh in central Florida. Data were collected in 6 split-plots (rooted and control) over 10 post-rooting, monthly sampling periods. Hog rooting led to reduced plant cover in broadleaf marsh habitats and to significantly higher microhabitat diversity and species richness. Although feral hogs can have detrimental effects on native biota and community structure, our data suggest that hog rooting is a disturbance that can enhance plant species richness and associated microhabitat diversity in wetland habitats.

“…Broadleaf marshes of the southeastern United States are defined by dominance of species with flag-like leaves, principally Sagittaria lancifolia, Pontederia cordata and Thalia geniculata (Davis 1943;Winchester et al 1985;Pezeshki et al 1987;Botts and Cowell 1988;Webb and Mendelssohn 1996). Broadleaf marshes are most commonly found in south and central Florida and southern Louisiana (Penfound 1952) in wetlands with prolonged annual inundation (i.e., hydroperiods >200 days per year) and wet season depths of 1 m or more (Kushlan 1990).…”

Restoration Response of Relict Broadleaf Marshes to Increased Water Depths

Broadleaf marsh once covered much of the wetland landscape along the Kissimmee River in central Florida, USA, but is currently restricted to remnant portions of the channelized floodplain that have been subjected to much shallower depths. The initial phase of Kissimmee River restoration, which began in 1999, and a prior (1984)(1985)(1986)(1987)(1988)(1989)(1990) demonstration project increased water depths in several relict broadleaf marshes on the floodplain. Effects of restored water depth regimes on characteristics of these altered broadleaf marsh communities were evaluated. As expected, plant species richness consistently declined in marshes with increased water depth, but cover of signature broadleaf species, Sagittaria lancifolia and Pontederia cordata, exhibited variable responses to restored hydrology. In one marsh mean cover of Sagittaria and Pontederia increased from 32 to 62% following a 37 cm increase in mean annual depths; however, in another relict marsh that underwent a similar increase in hydroperiods and depths, mean cover of these species remained below 30% and Panicum hemitomon persisted as a dominant species. Moreover, invasion of the exotic wetland shrub, Ludwigia peruviana, appears to pose a threat to successful restoration of broadleaf marshes on the Kissimmee floodplain.

“…Abiotic factors such as soil and water nutrients, dissolved oxygen levels, and soil moisture are distributed unevenly throughout the wetland environment, leading to patchy distributions of plant species (Winchester et al 1985, Patterson and Mendelssohn 1989, Scott et al 1989). Distributions of plant species, in turn, can affect invertebrate distributions.…”

We examined macroinvertebrate trophic relationships in stands of two emergent plants, pickleweed (Salicornia virginica) and alkali bulrush (Scirpus robustus), and in epiphytic and benthic habitats within pickleweed stands. Numbers of detritivores, predators, and herbivores were examined throughout the flooding season (October 1990-March 1991. Trophic structure of macroinvertebrate communities differed between epiphytic and benthic habitats; both herbivores and detritivores were abundant in epiphytic habitats, but detritivores alone were numerically dominant in benthic habitats. Macroinvertebrate communities also differed between pickleweed and alkali bulrush stands: (1) all trophic groups were abundant in pickleweed, but detritivores were numerically dominant in alkali bulrush; (2) pickleweed supported higher macroinvertebrate numbers than alkali bulrush. Species composition was similar in both vegetation types, and diversity decreased during the season. Macroinvertebrate trophic structure in the epiphytic habitats changed during the season; detritivores quickly colonized both vegetation types after flooding, and predator and herbivore numbers increased later. Herbivores were an important component of macroinvertebrate communities in these wetlands, indicating that algal herbivory may be more important than previously thought.
