1. An area in Kanata is known for having a high number of four leaf clovers, which is
believed to be due to a mutation that has occurred in the clovers. You want to be able to
estimate the number of four leaf clovers there are to decide how many of your campers
you will assign to get a four leaf clover in a scavenger hunt. How would you go about
estimating the number of four leaf clovers there are
a. Using the quadrat method
b. Percent Cover
c. Point/Line
d. Point/Pins
2. S
potted leopards are known for being difficult to spot in jungles due to how their fur
camouflages with the shadows for the vines and leaves. This is an example of which
difficulty in counting in ecology
a. Mobility
b. Visibility
c. Defining an Individual
d. None of the Above
3. T
he following image is of only one species. What can
you assume is true of the species below:
a. It is representative of the difficulty in defining
an individual in counting
b. This plant will be able to easily count via the
quadrat method
c. This plant is likely easily countable using the
unbound (distance) method since they can’t
grow two right next to each other
d. It is representative of the difficulty in visibility
when it comes to counting

efore starting a dive Joe marks a series of spots on his tape measure for him to use
when he counts the local seaweed population, by identifying how far the closest member
is from the point, then the second closest from the closest. What kind of equation should
be used after he counts the seaweed?

6. P retty much all mammals can not be counted using a bound method since they move
around. Birds have this same problem. In order to count them the mark and recapture
method is used. What kind of equation should be used if the population recaptured is
larger than 7?

7. U sing the mark and recapture makes several assumptions about the population. Which
of the following is an example of the ideal population for the mark and recapture
method?
a. A group of birds that join up with another population while immigrating and have
some migrate into the population as mates
b. A species where individuals are territorial and not often found in others territories
c. An isolated species of bird that live on an island all visit the capture site at similar
rates
d. A species of parrots who really like to collect scraps of plastic who regularly pull
off the their markers
. If you were asked to try and count the

following population of coral. Which method would
you choose
a. Percent cover
b. Quadrats
c. Mark and Recapture
d. Plotless
