Field sheet
: Explanation note: Field sheet to be compiled during each survey, for each transect. Each sighting is registered with a code, in the exact point of detection along the transect (path). Codes are reported on the right column of the field-sheet. Examples of codes: male in flight over 2 m – M2; female walk on the ground – F0; L. cervus with uncertain sex-determination, in flight below 2 m – U1.
