Section 04
Returns
One species removed, or added. Each entry names the species or the process and says what is actually observed, separating what is measured from what is inferred.

Medium entry
Grazing pressure
How much is eaten, by what, and how often.
Short entry

Short entry
Invasive arrivals
A species with no local checks, and how the term is defined and disputed.
