The Appalachian temperate rainforest is located in the southern Appalachian Mountains of the eastern U S About 351 500 square kilometers (135 000 square miles) of forest land is spread across southwestern ia western North Carolina northern Georgia and eastern Tennessee

Species richness alone does not predict cultural

Sustaining biodiversity and ecosystem services are common conservation goals However understanding relationships between biodiversity and cultural ecosystem services (CES) and determining the best indicators to represent CES remain crucial challenges We combined ecological and social data to compare CES value of wildflower communities based on observed species richness versus revealed

Impacts Of The Invasive FourEyed Fir Bark Beetle

The emergence and spread of non-native invasive forest insects represent a major potential threat to global biodiversity The present study examines the current invasion of the far eastern four-eyed fir bark beetle Polygraphus proximus Blandf in southern Siberian fir (Abies sibirica Ledeb ) forests

Description Ground-layer plant communities in spruce-fir forests of the southern Appalachians have likely undergone significant change since the widespread death of canopy Fraser fir (Abies fraseri) caused by the exotic balsam woolly adelgid (Adelges piceae) Bryophytes comprise an important part of the ground-layer flora in the spruce-fir zone with an average cover of 26 percent and richness

Plant Phenotypic Plasticity in Response to

Plants are exposed to heterogeneity in the environment where new stress factors (i e climate change land use change and invasiveness) are introduced and where inter- and intraspecies differences may reflect resource limitation and/or environmental stress factors Phenotypic plasticity is considered one of the major means by which plants can cope with environmental factor variability

Forests

Anthropogenic emissions have impacted terrestrial forest ecosystem processes in North America since the industrial revolution With the passage of the Clean Air Act in 1970 in the United States atmospheric inputs of nitrogen (N) and sulfur (S) into forests in the Appalachian Mountains have declined which have potentially mitigated their effects on processes such as decomposition and

Inter Research ESR v18 n1 p17

The competitive advantage of Fraser fir over red spruce has resulted in an even-aged Fraser fir-dominant forest that occupies a relatively early stage of successional development This study provides a 130 yr environmental history to assist land managers in the southern Appalachian Mountains as they develop long-term restoration plans for this
