News about endangered species isn't always bad. In Uganda, anyway, the elephants are staging a baby boom.

Eric Edroma, director of Uganda's national parks, announced the other day that his elephant population doubled in a decade. So spectacular a rise - from 1,350 in 1980 to an estimated 3,000 this year - is bound to prompt calls for a recount and an explanation. It reverses the trend for all of Africa: a fall from 1.3 million 10 years ago to half that now.

Edroma attributes Uganda's success to better training of park rangers who fend off poachers. If he's right, every park director in Africa should go sit at his knee.

Meanwhile, the international ban on the ivory trade, instituted in 1989, has slashed the cash value of tusks - another break for elephants. Maybe conservation efforts are paying off, and these marvelous beasts will even be around in our great-grandchildren's day.
