  • Sampling: Transect method to see effect of an abiotic Factor
    1. Set a Transect between area that is being investigated, with a Tape Measure
    2. Place Quadrats at Equal intervals along Transect Line
    3. Record Number of Plant Species in each Quadrat
    4. Record abiotic factor at each Quadrat
    5. Repeat Transect 2 more times
  • Sampling: Quadrat Method to find Population
    1. Use a random number generator to obtain 2 numbers, which are to be used as coordinates to find a location on the 2 tape measures set up.
    2. Set down the quadrat at the coordinates.
    3. Count and record the number of the required plant species in the quadrat.
    4. Repeat steps 1-3 to take 9 more samples.
    5. Estimate the population size using this formula: area sampled / total area x number of plant species counted
