It's not very convincing when the very first sentence is
"There is a lack of consensus among some conservation NGOs and African governments concerning the acceptability and effectiveness of trophy hunting as a conservation tool"
Better?

According to a recent study, in the 23 African countries that allow sport hunting, 18,500 tourists pay over $200 million (U.S.) a year to hunt lions, leopards, elephants, warthogs, water buffalo, impala, and rhinos.
Private hunting operations in these countries control more than 540,000 square miles (1.4 million square kilometers) of land, the study also found. That's 22 percent more land than is protected by national parks.
As demand for land increases with swelling human populations, some conservationists are arguing that they can garner more effective results by working with hunters and taking a hand in regulating the industry.
Sport hunting can be sustainable if carefully managed, said Peter Lindsey, a conservation biologist with the University of Zimbabwe in Harare, who led the recent study.
"Trophy hunting is of key importance to conservation in Africa by creating [financial] incentives to promote and retain wildlife as a land use over vast areas," he said.

The southern white rhinoceros grew from just 50 animals a century ago to over 11,000 wild individuals today, because hunts gave game ranchers a financial incentive to reintroduce the animal, the authors write.
Trophy hunting has also driven the reintroduction of cape mountain zebra and black wildebeest in South Africa, Lindsey said.
Hunters typically take just 2 to 5 percent of males annually from hunted animal populations, he added, which has a negligible effect on the populations' reproductive health.
