Overview
The angonoka tortoise is a critically endangered species of tortoise severely threatened by poaching for the illegal pet trade. It is endemic to Madagascar. It is also known as the angonoka, ploughshare tortoise, Madagascar tortoise, or Madagascar angulated tortoise.
There may be fewer than 400 of these tortoises left in the wild. It is found only in the dry forests of the Baly Bay area of northwestern Madagascar, near the town of Soalala. A captive-breeding facility was established in 1986 by the Jersey Wildlife Preservation Trust in collaboration with the Water and Forests Department.
In 1996, 75 tortoises were stolen, which later appeared for sale in the Netherlands. The project was ultimately successful, achieving 224 captive-bred juveniles out of 17 adults in 2004. Project Angonoka developed conservation plans that involved local communities making firebreaks, along with the creation of a park to protect the tortoise and the forests.
Monitoring of the angonoka tortoise in the global pet trade has also continued to be advocated.
The Angonoka tortoise faces severe population decline primarily due to illegal collection for the international pet trade, with individuals selling for thousands of dollars on black markets. Habitat destruction from slash-and-burn agriculture, charcoal production, and livestock grazing has fragmented the remaining dry deciduous forests of northwestern Madagascar. Introduced pigs destroy nests and compete for food resources, while fires set for cattle pasture eliminate critical vegetation cover.
