| Abstract |
|
Testudo graeca More than 300,000 tortoises are exported every year from Morocco to Britain for pets. To find out the effect of this trade on the populations in the wild, the author, aided by a grant from the FPS/WWF Revolving Fund, searched the known tortoise areas in Morocco, weighing and measuring all he found. In his six weeks in the field he found only 23 tortoises. For the country as a whole he estimates numbers to be of the order of five million, a very thin spread over a large area of ground. But the trade may have a more serious effect than just reducing numbers. Because only tortoises of 4–6 inches (under-shell measurement) are wanted, the collectors concentrate on these, which often leaves small mature males to mate with very large mature females. If they are unable to do so it could seriously affect reproduction rates. Added by: Admin Last edited by: Beate Pfau |
