Invasive Alien Species in Nova Scotia
MTRI ( Mersey Tobeatic Research Institute) Identification & Information Guide. 2012 Terrestrial species listed are Norway Maple (Acer platanoides), Oriental Bittersweet (Celastrus orbiculatus), Beech Bark Disease (Cryptococcus fagisuga, Neonectria spp.), Glossy Buckthorn (Frangula alnus), White Nose Syndrome (Geomyces destructans), Dutch Elm Disease (Hylurgopinus, Ophiostoma spp., & Scotylus spp.), Common Reed (Phragmites australis ssp. australis), Scots Pine (Pinus sylvestris), Rugosa Rose (Rosa rugosa). Glossy Buckthorn is prob the biggest threat to forests: “Tolerant of acidic conditions, this species is well adapted to invade a wide variety of natural habitats in Nova Scotia and may represent the greatest threat to plant communities in the province.”

Ten Years of Change in Beech Stand in North Central Maine Long Affected with Beech Bark Disease
MSC Thesis by Amada Farrar, University of Maine, 20013. American Beech was once an important component of our mixed Acadian forest but was severely impacted by beech bark disease incited by a scale insect that came to North America via Halifax. This study showed that clearcutting greatly increases mortality of seedlings from and spouts on disease-resistant trees and “demonstrates the importance of protecting resistant trees with uncut “islands” to insure their survival.

Spruce Budworm

Spruce Budworm on cue
Post on this website, August 18, 2016. The anticipated outbreak of spruce budworm is pretty well on cue (30-40 years between outbreaks), so one might wonder why such planning has not been integral to forest management policies since the end of the last outbreak (1983).
