Tracking Lion Recovery in
Gorongosa National Park
Scientists at Work
Student Worksheet
OVERVIEW
This worksheet complements the short video “Tracking Lion Recovery in Gorongosa National Park” from the
Scientists at Work series.
PROCEDURE
1. Prior to watching the film, read the questions below.
2. Watch the film.
3. If working with a partner or in a small group, discuss and answer the questions below. If working alone,
think about and answer the questions below.
QUESTIONS
1. Technology has changed the way scientists conduct their research. Provide two pieces of evidence from
the film to support this claim: “Technology is crucial for lion research in Gorongosa National Park;”
2. Two of the researchers in the film, Celina and Domingas, are from Mozambique, the country where
Gorongosa National Park is located. For global restoration and conservation initiatives, list two reasons
why it is important for the park to employ local people.
3. The lion researchers in the film have studied 20% of the park and identified 41 lions. (Show your
work/justify your answer for each section.)
a. The entire Gorongosa Park is 4,000 km
2
. Approximately how large (in km
2
) is the portion of the park
that has been studied?
b. What is the density of lions (in lions/km
2
) in the portion of the park that has been studied?
c. Assuming that the density of lions is the same throughout the entire park, about how many lions are
there total in Gorongosa National Park?
d. The 20% of the park that has been studied has roads, so it is accessible by vehicle. Based on this
information, do you think it is more likely that your estimate from part (c) is too high or too low?
Explain your answer.

4. Figure 1 is an example of a food web that includes lions. Use the food web and any information from the
film to answer the following questions:
Figure 1. A food web in Gorongosa National Park.
a. On average, 10% of the energy from one trophic level is available to the next level. Approximately
what percentage of energy is available to the lions (secondary consumers) in the ecosystem
represented in Figure 1 (assuming the primary producer level represents 100% of the energy)? Show
your work to justify your answer.
b. Use scientific reasoning and the food web to explain why, in general, it makes sense that the lion
population is taking longer to recover than the herbivore populations.

5. Researchers use two rows, the reference row and the identification spots:
The reference row is the top complete row of whisker spots
The identification spots form an incomplete row above the reference row. There may be up to 5 spots.

Student Worksheet
Use this information to draw the reference row and identification spots for the lion below, which was in
the video. In the space to the right, write a description of the identification spots in relation to the
reference row.
6. Researchers have discovered that the pride territory defended by a male lion can extend 330 km
2
. Explain
how the scientists used GPS collars, satellites, and computers to determine the size and geographic
distribution (shape) of a lion pride’s territory.
7. If you joined the research team shown in the film, what new scientific question would you like to try to
answer?
