Nitrogen is typically the most limiting macronutrient in boreal and temperate forests because slow decomposition rates limit nitrogen mineralization from organic matter.

In the Greater Yellowstone Ecosystem, while wolves do prey on bison, elk are by far the majority of their prey items. Bison are large and formidable, making them a more challenging target for wolves compared to elk. The other statements about bison in Yellowstone are generally true, including their brucellosis concerns, population growth after natural fluctuation, and the legality of killing them outside the park.

Air-drying uses natural air circulation around stickered lumber stacks outdoors or in open sheds to slowly reduce moisture content without mechanical drying.

Bounties, while historically used, are generally considered an ineffective and often counterproductive wildlife management strategy. Instead of effectively controlling populations, they frequently lead to fraud, indiscriminate killing, and the removal of only the "annual surplus" that would naturally be lost, rather than significantly reducing the breeding population. Modern wildlife management focuses on more targeted and ecologically sound approaches.

The overstory is the uppermost canopy layer composed of the tallest dominant and codominant trees that intercept most of the incoming solar radiation.

A forest stand is a contiguous group of trees that possesses sufficient uniformity in species composition, age class, structure, and spatial arrangement to be distinguishable from adjacent groups. This consistency allows foresters to manage it as a single unit for silvicultural treatments, harvesting, and inventory purposes. It is a fundamental unit of forest management.
