AEST Natural Resource Specialist Study
Guide with 100% Correct Answers
Chytridiomycosis
A disease that effect amphibian species, early signs are anorexia and lethargy. common signs are red
skin, lack of reflexes, and abnormal feeding behavior
Coppice Cutting
Similar to seed tree cutting concept. Rather than providing seed, the remaining trees develop root
suckers to produce new trees.
central broad-leaved forest
Mostly east of the Mississippi River and south of the North Hardwood forest. High quality wood
produced here. Abitrary grouping of several distinct forest subgroups. Farming region, most land
cleared to cultivate crops
Tropical Forest
The forest located at the southern most tip of Florida and Texas. Has little economic usage but very
important ecologically.
Southern Forest
runs from the coast of Virginia to eastern Texas and North to Missouri
A horizon
Soil Horizon that has the highest amount of organic matter
Learned Behavior
What type of behavior is a duckling learning how to swim
adaptive behavior
What type of behavior is a deer camouflaging itself from predators
Entisols
Which soil order has little to no horizon development except the A horizon
Alfisols
Soil order with lots of clay accumulation and a base saturation of 35% and up
Andisols
developed from volcanic material, particularly ash
Aridisols
dry soils found in most desert areas; salinization common
Gelisols
, cold & frozen soils subject to crytoturbation (frost churning); found in high latitudes & elevations, has
permafrost in soil
Histolsols
Soil order high in organic matter
Inceptisols
soil order with weakly developed horizons but also my have other characteristics of other soil orders
Mollisols
Soil order with a base saturation of at 50% or above and thick and dark surface horizon
Oxisols
Soil order with low cation exchange capacity rich in Iron and Aluminum minerals
Spodosols
Soil order that has sandy soil but has a thick spodic layer/organic matter/Humus
Ultisols
Soil order with a base saturation below 35% and clay accumulation
Vertisols
clayey soils with high shrink/swell capacity
clear-cutting
a method of harvesting trees that involves removing all or almost all of the trees within an area
Selective Cutting
Cutting down individual trees for harvesting based on maturity, size, species, growth rate, or other
factors. Allows for annual reproduction and income for harvesting.
Seed-tree cutting
Cutting almost the entire stand and leave a few trees standing based on their quality and seed bearing
ability
Thinning
The timber-harvesting practice of selectively removing only smaller or poorly formed trees to make
way for
Salvage cutting
When enough trees are affected of damaged that harvesting them would have and economic impact.
Damaged trees are harvested for wood
bottomland hardwood forest
