  2. Wood density

  3. Nitrogen fixation ability

  4. Pollination efficiency
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pollination efficiency is not typically measured as a functional trait in forestry, as it is more relevant to ecological studies of plant-pollinator interactions.

Multiple choice

Which of the following is NOT an example of a functional trait that can be used in functional trait-based forestry?

  1. Leaf area index

  2. Wood density

  3. Nitrogen fixation ability

  4. Tree height
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Tree height is a structural trait rather than a functional trait. Functional traits are those that directly influence an organism's ecological role or function.
