Count what was observed without claiming a complete inventory
Count observed kinds within a stated area and time.
A ten-minute look at one garden patch creates a bounded sample. Write down the area, time and method so readers can distinguish observed variety from a claim about every organism that might live there.
Agree on what counts as a distinguishable kind in this sample. A short visual survey is not a complete species inventory.
A sample has a boundary
Four observed kinds in ten minutes is a sample record.
Define the boundary. Record distinguishable kinds. Describe the limits.
What did the sample leave out? Use labelled photographs.
Unseen organisms have not been proven absent.
