Current Issue: B2_Forest Health Issues Facing the Boreal Forest Flashcards
(24 cards)
What is the Asian Longhorned Beetle?
An invasive forest pest native to China and the Korean peninsula that primarily attacks maple and other hardwood tree species.
What is the Spongy Moth?
An invasive pest that defoliates trees by eating their leaves, with a wide range of host trees. Known for its distinctive larvae with blue and red tubercles.
What is the Emerald Ash Borer?
A highly destructive invasive beetle native to eastern Asia that attacks and kills ash trees by tunneling through the cambium layer.
What is the Satin Moth?
An invasive moth whose larvae feed on poplar and willow species, causing defoliation that can lead to reduced growth and tree mortality.
What is the Mountain Pine Beetle?
A native bark beetle that is a significant pest of pine trees, particularly lodgepole pine. Its spread and impact are being influenced by climate change.
What are Invasive Species?
Organisms introduced to an area outside of their native range that cause ecological or economic harm.
What is Defoliation?
The loss of leaves from a tree or plant, often caused by insect feeding.
What is the Cambium Layer?
A layer of actively dividing cells between the xylem and phloem vascular tissues of a plant, responsible for secondary growth (increasing in width).
What is Girdling?
The complete removal of a strip of bark around a tree, which interrupts the flow of nutrients and water, leading to the death of the tree above the girdle.
What is Frass?
The excrement of insect larvae, often visible as sawdust-like material beneath infested trees.
What are Hibernacula?
Silken coverings spun by insect larvae to overwinter.
What are Pheromones?
Airborne chemical signals used by insects for communication, including for mating.
What are Saprophytic Fungi?
Fungi that obtain nutrients from dead organic matter.
What are Bioclimatic Zones?
Geographic areas characterized by similar climate conditions that support specific types of ecosystems and species.
What is Timber Supply?
The amount of wood available for harvesting from a forest.
What is Salvage Material?
Timber from trees that have been killed by natural disturbances such as insects or fire, which can still be harvested for value.
What are Disturbance Regimes?
The frequency, intensity, and spatial distribution of natural disturbances such as fires, insect outbreaks, and droughts in an ecosystem.
What is Permafrost?
Ground that remains frozen for at least two consecutive years.
What is Nature-based Recreation?
Recreational activities that take place in natural settings, such as hiking, camping, and wildlife viewing.
What is Recreation Ecology?
The scientific study of the environmental impacts of recreation and tourism activities.
What is Trampling Disturbance?
The impact on vegetation and soil caused by foot traffic or other forms of movement.
What are Ruderal Species?
Plant species that are able to colonize disturbed habitats quickly.
What are Vectors for invasive species?
Agents, such as humans or vehicles, that transport invasive species to new locations.
What are Adaptation Strategies for Climate Change?
Actions taken to adjust to current or expected future effects of climate change.
