Pulse of the Predator

SCHALLER – PredatorsCelebrating three decades of Pulse of the Planet, here’s a program from our archives.Ambience, Lions We’re listening to the sounds of one of nature’s master predators – the African lion. To know what the future holds in store for the lion and other predators, we need to understand their role in their ecosystem. I’m Jim Metzner and this is the Pulse of the Planet.(Schaller) “You’re not just studying one animal, you’re studying a whole spectrum of species, most of which then are eaten by the predator. “George Schaller is Director of Science at Wildlife Conservation International. He’s spent much of the past thirty years studying predators in the wild.(Schaller) “Part of the study is to see what impact do they really have on the livestock. Or for example, in the Serengeti, one wanted to know what effect do the lions have on these wonderful migratory herds of wildebeest and gazelle and zebra and so forth. Because if you’re going to manage an area, the predator’s an integral part of it.” “Humans encroach in one way or another, and they automatically become competitors with the predators. So you need to try to measure what effect do the cats, or the big canines like the wolf, have on the prey population. What effect do the humans have on it? How then can you manage the ecosystem, not just for the next few years, but for the centuries ahead. And so you get baseline information on the interaction between these animals.”This archival program is part of our thirtieth anniversary celebration.
