Aerial dispersal of Lygodium microphyllum spores within Arthur R. Marshall Loxahatchee National Wildlife Refuge

May 1, 2022

Native across the Old World tropics from Africa to Southeast Asia and Australia, Lygodium microphyllum (Cav.) R. Br. (Old World Climbing Fern) is one of the most invasive plant species threatening South Florida ecosystems (Rodgers et al. 2014). This invasive fern was first collected as a naturalized plant in South Florida in the late 1960s (Beckner 1968). Subsequent populations were observed in the late 1970s in both Martin and Palm Beach Counties (Nauman and Austin 1978). In 1989 L. microphyllum was observed by the South Florida Water Management District (SFWMD) in the Arthur R. Marshall Loxahatchee National Wildlife Refuge (LNWR). In 1995, a survey by SFWMD indicated that 12% of LNWR was colonized by L. microphyllum. By 1997 this had increased to 36% (Ferriter 2001). Ten years later, Systematic Reconnaissance Flights conducted over LNWR estimated that 44% of LNWR had sparse (> a single individual tree, shrub or stem to <50%) or dense (>50%) infestations of L. microphyllum
