Interesting Tidbits
Green Mountain Maidenhair Fern arose as an allotetraploid cross (that is, it retains four instead of two sets of chromosomes) between Common Woodland Maidenhair (Adiantum pedantum) and Aleutian Maidenhair (Adiantum aleuticum). It is only found in dry, rocky, nutrient-poor areas known as ""serpentine"" habitat in southeastern Quebec and northern Vermont. Although uncommon, populations of this fern seem to be extremely stable. Human interference is rare, for the soil quality is too poor for farming or forestry. Mining activities and horticultural collecting, however, remain potential threats. (New England Wildflower Society document: http://www.newfs.org/pdf/Adiantumviridimontanum.pdf) As of August, 2005, this plant is a candidate for inclusion on the endangered species list of COSEWIC (Committee on the Status of Endangered Wildlife in Canada). Road construction has lately become another threat to this species. Few animals have been noticed to browse on this species most likely attributed to the fact that the leaves contain high levels of secondary compounds, including tannins and phenols.
