Background
In this lab, we are going to explore elephants, their current status, and
discuss why it is so important to survey them. This ties in to the scientific
method:
Ask A Question
Do Background Research
Construct A Hypothesis
Test with an Experiment
Analyze Data and Draw Conclusions
Communicate Results

Survey Methods for African Elephants
Read the “Why Study Elephants” page and answer the following
questions:
1.
What is the question that scientists are trying to address with this
study?
2.
What is a potential hypothesis for an experiment involving these
elephants?

how many remain, where they live, and how the populations
are changing
Is habitat loss one of the main reasons that the elephant
population is declining ?

3.
Elephants are considered to be a keystone species. What does that
mean?
4.
Name three elephant activities or functions that justify the term
“keystone species” and describe how the activity changes African
ecosystems.
Elephant Activity
Change in Ecosystem
dig water holes
Produce areas for other animals to
drink
Knock down trees
Provide space for new growth
knocking down trees
Maintain open grasslands
5.
Why have elephant populations been declining for the past several
decades?
Click on the Species Range
6.

7.
Review the Methods, Advantages and Disadvantages of the
Species Range data collection; add your thoughts in the table on
the last page of this packet.
Click on Individual Range.
8.
Take the time to watch the video! In general, why to elephants
move across the land?
9.
Why do we only have to collar one mature female to get a lot of
data of movement of a group and not all individuals?
10. Review the Methods, Advantages and Disadvantages of the
Individual Range; add your thoughts in the table on the last page of
this packet.

to find suitable habitat
because they roam in groups

Review the methods in the How Many section.
11.Discuss the methods, sample type, advantages and disadvantages
of each in the table at the end of this packet.
Click on the Population Change. Review the video, and read the
introductory material.
12.Turn on both the 1979 and 2007 range for the elephants on the
map. How did the range change? Did it increase, decrease or stay
the same?
13.
Turn off the 1979 and 2007 range layers, and turn on the 2016 trends
layer. What types of changes do you notice? Are there specific

you think this is?

the higher human population areas have less
elephant populations.
It is caused by the humans removing healthy
habitat that the elephants need to survive
