By way of a summary of all the data collected by the mapping teams, I will review what is entered on each of the data sheets. The map sheet was already de scribed in some detail (Fig. 2.2.1A), and includes a circle or a point for the location of each tree and the tree's tag number (the last three or four digits) written next to it. The range of tag numbers used in the quadrat should be written at the top of the sheet. The main data sheet is where most other information about each individual is recorded (Fig. 2.2.1B). As for all sheets, the quadrat number, the first date a quadrat is censused, and the mappers' names are recorded at the top. For each plant, there are blanks for the following information: subquadrat number, tag number, species name, dbh, codes, and problems. Subquadrat number and tag number are straight forward. Size in millimeters is entered in the dbh column, except for multiple stemmed plants or big trees, which get a blank dbh on the main data sheet. Species identification will be handled by separate taxonomy teams (chapter 2.3), but map pers should enter a species name if they know it.

The book provides a detailed overview of data collection methods used by mapping teams, focusing on the organization of information on data sheets. It describes how each tree's location is marked with a circle or point, accompanied by its tag number. The main data sheet captures essential details for each plant, including subquadrat number, species name, and diameter at breast height (dbh). Specific instructions are given for recording data, with taxonomy handled by separate teams, ensuring a comprehensive approach to ecological mapping.
