One odd group of vining plants is the fern genus " Lygodium ", called climbing ferns.
2.
Some " Lygodium " species are now considered very problematic invasive weeds in the southeastern United States.
3.
Old World climbing fern ( " Lygodium microphyllum " ) infests cypress swamps and other hydric sites, forming a monoculture.
4.
The species that is causing the most impediment to restoration is the Old World climbing fern ( " Lygodium microphyllum " ), introduced in 1965.
5.
Invasive species, such as " Lygodium microphyllum " and " Bromus tectorum ", can grow rapidly in areas that were damaged by fires.
6.
Populations of " Lygodium " have increased more than 12-fold over the past decade, as noted by Florida's Institute of Food and Agricultural Sciences.
7.
Several ferns are noxious weeds or invasive species, including Japanese climbing fern ( " Lygodium japonicum " ), mosquito fern and sensitive fern ( " Onoclea sensibilis " ).
8.
The Old World climbing fern ( " Lygodium microphyllum " ) may be causing the most harm to restoration as it blankets areas thickly, making it impossible for animals to pass through.
9.
I fell for two other charmers there : a vining fern, Lygodium sandens, with little filigreed leaves, and Philodendron verrucosum, whose satiny leaves are emerald green, with violet-black shimmering between the veins.
10.
Japanese climbing fern ( " Lygodium japonicum " ) was added to the Florida Noxious Weed List in 1999 . It is also a major problem in pine plantations, causing contamination and harvesting problems for the pine straw industry.
