Excerpt from Survey of Semiothisa Fraserata (Geometridae) And Gazoryctra Sciophanes (Hepialidae) In the Southern AppalaciansThe reason for this concern was that both species are southern Appalachian endemics confined to Fraser fir forests which has undergone dramatic decline due to defoliation by the introduced balsam woolly adelgid. Large areas of extensive dieback may be followed by regeneration, but many areas have been depleted of Fraser fir cover and associated ecology (see cover illustration).About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
