Therefore, introducing reproductive ecological analog giant tortoises is a viable restoration strategy for Pinta Island. Giant tortoises of the Galapagos Islands - all you need to know about these. Simulations of aggregated tortoise-vegetation interactions indicate that greater tortoise densities could reduce woody plant encroachment through herbivory and trampling. The last known living Pinta tortoise died in 2012 his name was Lonesome George. Habitat selection differed between phenotypes, with the saddlebacked type most closely replicating Pinta tortoise ecosystem services through selection of areas with high densities of adult Opuntia cactus.
#Pinta tortoises trial
A trial group of 39 adult, non-reproductive, mixed ancestry tortoises were introduced to Pinta Island in May 2010, and their behaviors and interactions with the plant community were monitored following release. He was the last surviving land tortoise from Pinta Island, one of the northern islands in the Galápagos. Ecological analog giant tortoises could replicate some lost services, but it is unclear whether they will be effective or how best to implement them. On June 24, 2012, the world-famous giant tortoise affectionately known as Lonesome George passed away. The semi-arid ecosystem on Pinta Island, Galápagos, has experienced woody plant encroachment, likely due to the loss of ecosystem services once provided by the Pinta tortoise and the effects of now eradicated invasive goats. Université de soutenance : State University of New York The tortoise found only on Pinta Island ( Chelonoidis abingdoni) went formally extinct in 2012, when its last representative, a male held in captivity and nicknamed Lonesome George, died.
