### Section 2. Early Years: 1903–1920 (Part 1)

- 10 elephants were found around the Letaba and Oliphant river in 1905
- Elephant numbers began increasing

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 ** r _{max} = 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

The elephant population was growing unhindered, because they were in essence “invading” this new, protected habitat. There was plenty of food and space for reproduction and survival.

It is likely that Colonel Stevenson-Hamilton witnessed an increase of 2 elephants, because the population was so small then.
