Using RIC Dataforms:

See Table 1 to determine what forms are necessary for the survey type chosen.

Ensure forms are filled out correctly by checking the coding instructions provided with each form (it will also indicate which fields are mandatory and which are optional). Dataforms and codes that are generic to all surveys are found in the Species Inventory Fundamentals No. 1 [Forms] (previously referred to as the Dataform Appendix) .

Some forms have more than one part (e.g. A and B). All sections of a form must be filled out. In many cases, forms will be double-sided and both sides will be the same.

Computer Buttons that appear next to groups of fields correlate to the Data Form Hierarchy and are used to assist Digital Data Entry.

Comments

Indicate that a territory for a particular bird is present within the plot area by recording a '1'. For territories that occur along the edges of the plot, estimate the proportion of the territory enclosed within the plot and record it as a fraction. There is a minimum number of detections required before a territory can be accepted and this relates to the number of plot visits as follows (Arbib, 1970): Number of valid visits: 10 : 9 : 8 : 7 : 6 : 5. Number of corresponding detections: 3 : 3 : 3 : 2 : 2 : 2.
