There are two kinds of elephants in Africa: the forest elephant and the savanna elephant (above), photographed this past spring in Liwonde National Park in Malawi.

The Shire River is the largest river in Malawi. A 17-mile section of the palm-tree-lined waterway runs through the heart of Liwonde National Park.

Liwonde field operations manager Lawrence Munro uses the EarthRanger program, which gives enforcement officials a visual representation of snares found in the park over the past month.

Paul Chidyera, head of law enforcement at Liwonde, is surrounded by some of the snares his team picks up in the park.

Zione Mzakwacha, a parks and wildlife assistant at Liwonde, receives information from rangers via radio.

Elephants approach a road at Liwonde. Reid says the park hasn't lost a single high-value animal in 30 months.
