Title: PRRP Songbird
1PRRP Songbird Monitoring Proposal
Travis Crane, Chandler Mundy, Travis Mote, and
Morgan Mendenhall
2Objective
Develop a monitoring plan to be used with habitat
management in order to double the number of bird
species on the ten-mile Provo River restoration
project.

13Characteristics of the indicator species
1. Species must be relatively easy and
inexpensive to monitor. 2. Indicators should
be sensitive to the environment and will
fluctuate in the same manner as their guild. 3.
Species have direct relationship to target
population. 4. Most importantly, indicators
should meet managements objectives of being
adequate predictors of the target population.

23Statistical Software
Computer programs will be heavily used to
calculate and interpret data using statistical
tools.
24Chi-Square Test (?2)
?2observed-expected expected
25Paired T-test
- Compare 2 or more years
- Sampling units permanent
- Measurement Data
- Data grouped in transects or clusters
26Paired T-test
- Is there a statistically significant result?
- What is the likelihood that no true change
occurred and that any observed difference is the
result of random sampling error? -
- Does the observed change have any biological
significance?
27Does the observed change have any biological
significance?
The power value uses the sample size, sample
standard deviation, threshold significance level
(a) and an effect size considered biologically
important. The minimum detectable change is
another calculation to judge biological
significance. It uses the power value to
calculate what minimum level of change could be
detected.
28Species diversity and richness
Species richness is analyzed as a total number of
species detected. Evenness, or the relative
abundance of a species, is incorporated with
species richness into a diversity index. Many
indices exist we will use the Shannon-Weaver
index
29Sampling Design
Detect a minimum change of 20 with a 95
confidence level
- Ensure capture of population variation
- Ensure narrow confidence interval
- ? Low bias, no 0s
- ? Increased precision
- Determine number of samples and plot size
