In March, 2000, a group of four scientists from USA, Mexico, and Australia began planning for a trip to Guadalupe and Cedros Islands, Mexico with the goal of making genetic collections from the remaining native Monterey pines (Pinus radiata) on these islands for restoration, conservation, and research purposes. The situation on Guadalupe was particularly compelling, because only a small number of trees, mostly over mature, remain there. Goats were introduced to the island more than a century ago and any seedlings are quickly eaten by their numerous descendants.
