Section 3. Growing Years: 1921–1940 (Part 1)
Calculate values for the “unused portion of K, [1-(N/K)]” (round up to the second decimal) and for the population growth rate (ΔN/Δt) (round up to the nearest highest whole number). The values of N used here are estimated from the model using rmax = 0.15 and K = 7500 (you will look at the actual recorded data for N later in this lesson). Click here if you need help.
In the park
Human populations were definitely growing larger at this time in South Africa, but so were the elephants in KNP. The national park system was doing a good job at preserving this threatened species.
