Counting
How any of this is actually known. Each entry names the species or the process and says what is actually observed, separating what is measured from what is inferred.
How any of this is known
Quadrats, transects and repeat visits. Most ecological claims rest on somebody counting the same square metre for years.
Medium entry
The quadrat
A square frame thrown down, and the discipline of where it lands.
Short entry
Transects
A fixed line walked repeatedly, and why the route must never change.
Short entry
Indicator species
Using one organism as a proxy for conditions, and the limits of that.
Short entry
Long runs
Datasets decades long, and why the old ones cannot be replaced.
