Terms 2 Flashcards
Hypoxylon canckers
Weakened point that breaks 10-15ft up. White trunk rot - fruiting bodies on trunk, happens on mature trees, rotation harvest more frequently and change species as it lives in soil.
Oak wilt
Exotic fungus. Red and Black oak more susceptible than whites. Orange leaves earlier, goes from leaf edge inward on reds, white top down color change
Fungal mat under bark, cross section is black streaks and black dots on xylem. Spread by insects and root graphing. Cut 2 chains further than visible
Climax forest
Tolerant species need to be able to reproduce under a canopy of mature trees
Mycology
Study of fungi
Fungi spread by spores, different spore types and during different life cycle points
Hyphae
underground or on root tissue. Stringy feed and grow underground
Armillaria
Pines, weaken trees, more susceptible from bugs, drought, etc. Base of tree has rot and white under bark. Decomposes in soil until in finds a host (Saprophyte). Root rot, keep trees vigorous. Mycelial fan (white tendrils) and Rhizomorphs black strings
Mychorrhizae
Fungi are symbiotic with plant roots. Feeds off of energy from plant and creates more root surface area to help with absorption of water and nutrients.
Rust fungi
Jack pine, oak-pine rust or pine-pine gall rust
Deciduous growing conditions
Long, warm, humid. More nutrient availability, better sites
Sugar Maple (hard maple)
Sinus and samaras U shaped
Sun vs Shade leaf
Shade leaf is broader with more surface area
Sun leaf has deeper sinuses, a little smaller
Eastern deciduous forest
Not fire adapted, main disturbance is wind. Suppressed trees waiting for sun/disturbance. Oak, Maple, Beech, yellow birch
American Chestnut
Largest DBH, 25% of all stems before FHP. Nuts for livestock, rot resistant. Chestnut blight from Asia, spread 24 miles a year. Red/orange canker spread by wind, bird, rain, insects. Rarely large trees mostly sprouts. Cross bread with Asian chestnut. Hypovirulent fungus to heal and take up space of blight
Evapotranspiration
Water transferred to atmosphere by evaporation from soil and other surfaces and by transpiration or release of water vapor from plants.
Swamping out
Loss of trees in wetland. Cannot replant due to elevated water table. Water table stays low due to trees using water and evaporating from stomata.
Silvics
Knowledge about specific species characteristics. Especially life history and environment
Silviculture
Art and science of managing the growth of forests to meet out needs in a suitable way
