Beyond the marsh edge and onto higher ground is the maritime forest. This habitat type boasts a canopy of various trees that tower above the landscape and includes pines, live oaks, hickories, and other hardwoods. Lying underneath the canopy is a biodiverse plant community tolerant of the shady conditions produced because of the canopy. Below the canopy and above ground level is an understory comprised of small trees and shrubs. Vegetation in the understory are typically more tolerant of shady conditions and include woody plants such as magnolia, red bay, yaupon holly, wax myrtle, and dwarf palmetto. Below the understory is a range of hardy small shrubs, forbs, ferns, and grasses that dwell on the forest floor. These habitats vary across the Island, containing various combinations of plant species that make them unique. A vegetative survey of Kiawah Island conducted by Dr. Joel Gramling identified these various plant assemblages (2013). Following the study, he identified six types of maritime forests, six types of shrublands, three types of open dunes/ grasslands, and eight types of marshland/marsh edge habitat. Each habitat is unique, and the horizontal layers provide various benefits to wildlife. This lateral layering results in increased wildlife activity and species diversity in areas where habitat transitions occur. Raptors (for example, ospreys and hawks) like to nest in areas with high canopy and quick access to open areas. This is why osprey nests are typically in trees next to the marsh, and hawks nest near forest edges and open parks. Kiawah’s bobcats utilize the various shrub thickets for easy access to prey and cover for daytime nesting and resting. The niche habitats provided by by the various layers of vegetated WINTER/SPRING 2020 • VOLUME 42 communities on Kiawah Island allow wildlife to flourish. Because of residual development and the related creation of open spaces, natural areas have become fragmented across the Island, disconnecting and diminishing some of the nuances provided by large expanses of natural habitat. However, many wildlife species continue to thrive despite these circumstances. Adapting where they can, many species use corridors as their mainstay for moving and traversing across open spaces when necessary. Even small pockets of natural habitat can provide corridors for wildlife to move as well as other benefits provided by this type of vegetation. These pockets of habitat can include our residential landscapes—everything from the vegetative buffers between homes to plants around houses and forest edges. Incorporating these landscape elements effectively expands the habitat that wildlife can utilize. Including plants in our residential landscapes that mimic the layering effect of nearby habitat through groundcover, understory, and canopy vegetation enhances this utilization. The result is the increase in the quantity of habitat, which provide shelter, cover, and nesting and resting areas for Island wildlife. The quality of our human-created habitats is also an important aspect of this process. Playing a critical role in providing wildlife qualities in our landscapes are native plants. By including layers of vegetation that are comprised of native plants, these niche habitats for wildlife are essentially mimicked. Not only does this beautify the landscape, but it also provides a suite of benefits to the ecosystem and biodiverse wildlife found on Kiawah. NK 33
