Population Sampling
Measuring Population Size
• Census (count EVERYTHING?!?!)
• Sampling
  – Lincoln Index (capture, tag, recapture)
  – Quadrat (count in a small sample area,
    apply to entire area)
Lincoln Index

population size = (n1 X n2)/n3



where . . .
• n1= number of individuals initially caught, marked and
  released
• n2 = total number of individuals caught in the second
  sample
• n3 = number of marked individuals in the second sample
Quadrat Method
• Random sampling of plant species
  usually involves counting numbers
  in small, randomly located, squares
  within the total area.
• These squares are usually marked
  with frames called quadrats.
Quadrat Method
•  Mark out gridlines
   along two edges of
   the area
• Use a calculator or
   tables to generate
   two random
   numbers to be used
   as coordinates.
   Place a quadrat at
   the coordinates
Example: 14, 31
Quadrat Method
1. Count how
   many
   individuals
   are inside
   the quadrat.
2. Repeat steps
   2 and 3 as
   many times
   as possible.
Quadrat Method
1. Measure the total
   size of the area
   occupied by the
   population, in
   square meters
Quadrat Method
1. calculate the mean number of
   plants per quadrat. Then calculate
   the population size using the
   following equation:

   Population = (quadrat mean X total area)
                     quadrat area

Sampling

  • 2. Measuring Population Size • Census (count EVERYTHING?!?!) • Sampling – Lincoln Index (capture, tag, recapture) – Quadrat (count in a small sample area, apply to entire area)
  • 3. Lincoln Index population size = (n1 X n2)/n3 where . . . • n1= number of individuals initially caught, marked and released • n2 = total number of individuals caught in the second sample • n3 = number of marked individuals in the second sample
  • 4. Quadrat Method • Random sampling of plant species usually involves counting numbers in small, randomly located, squares within the total area. • These squares are usually marked with frames called quadrats.
  • 5. Quadrat Method • Mark out gridlines along two edges of the area • Use a calculator or tables to generate two random numbers to be used as coordinates. Place a quadrat at the coordinates Example: 14, 31
  • 6. Quadrat Method 1. Count how many individuals are inside the quadrat. 2. Repeat steps 2 and 3 as many times as possible.
  • 7. Quadrat Method 1. Measure the total size of the area occupied by the population, in square meters
  • 8. Quadrat Method 1. calculate the mean number of plants per quadrat. Then calculate the population size using the following equation: Population = (quadrat mean X total area) quadrat area
