Quadrat+Math

=**A run down on determining population sizes from a quadrat sample.**=


 * 1. Determine the area of the whole quadrat (18' x 18'; or whatever the dimensions are). This will be "A"**
 * 2. Start with one species (you will do the following to each species type). What were the numbers listed for each of the smaller (in this case circular) quadrat? (for example: 2,4,7,6)**
 * 3. Determine the average for this species. {(2+ 4+ 7+ 6) / 4} = 4.75 of this species in the whole quadrat.This number will be "B"**
 * 4. B x A = the number of individuals in the whole quadrat.**
 * 5. You will repeat steps 2-4 for each species.**

So, for example: 1. 25' x 16' = 400' (you should NOT leave this as feet, you should convert to meters) 2. We are going to look at the pink ant population. 8, 2, 4, 6 were counted 3. {(8+2+4+6) / 4} = 5 is the average 4. 400' x 5 = 2,000 pink ants in this quadrat.
 * example:**
 * In a quadrat that is 25' by 16' the following organisms were counted:**
 * ~ Species ||~ Quad 1 ||~ Quad 2 ||~ Quad 3 ||~ Quad 4 ||
 * Pink ant || 8 || 2 || 4 || 6 ||
 * orange grape-eater || 2 || 1 || 0 || 8 ||
 * golden fern || 3 || 4 || 2 || 1 ||
