Invasive plants are another concern with maritime forests , as they compete with native vegetation for resources . This results in a decrease in native plants , which provide critical resources and nutrients to local wildlife and pollinators . Monarch butterflies , in particular , are fond of milkweeds which provide essential sources of nectar for butterflies and serve as suitable host plants during their larval stage . Swamp milkweed ( Asclepias incarnata ) is an important host species for monarch ’ s in Charleston County . Other native plants such as blue mistflower ( Conoclinium coelestinum ), spotted beebalm ( Monarda punctata ), and seaside goldenrod ( Solidago sempervirens ) are also important host species for a variety of local pollinators . Monitoring data from our annual Naturally Kiawah assessments show that over 750 residential areas contain instances of invasive plants species , primarily thorny elaeagnus , Chinese tallow tree , and / or exotic non-clumping bamboo . These non-native , invasive species out compete native plants , resulting in negative impacts to biodiversity and ecosystem integrity .
Chinese Tallow Tree : Spring and Summer Foilage Chinese Tallow Tree : Seed Pods Chinese Tallow Tree : Fall Foilage
The most widespread and aggressive invasive plant on Kiawah Island is the Chinese tallow tree ( Triadica sebifera ). Freshwater wetlands , which are often seasonal in nature , are highly vulnerable to the establishment and growth of these trees . These freshwater wetlands are important because they provide critical habitat for reptiles and amphibians – especially tree frogs , and also provide sources of freshwater to mammals . As tallow trees become entrenched and their density increases , freshwater wetlands begin to dry up , and native species diversity is diminished . Due to their detrimental effects , the Kiawah Conservancy advocates for management plans that treat or remove this invasive species
