Huge 100-pound African tortoise found roaming Arizona desert
The tortoise had been living in the Arizona wild long enough to establish two burrows and was likely released there when it grew too large to contain.

Tortoises native to the Arizona desert rarely grow in excess of about 15 pounds, so officials with the Arizona Game and Fish Department were quite surprised when they recently came across a huge 100-pound tortoise living comfortably in the Sonoran Desert.
 
Probably kept as an exotic pet and released into the Arizona wild by its careless handler, the behemoth reptile was an African spurred tortoise, according to Wildlife Extra News.
 
"Finding an exotic tortoise this size inhabiting the Sonoran Desert is a reminder of how important it is not to release any exotic species into the wild," said Cristina Jones of the Arizona Game and Fish Department.
 
Because they are native to the southern edge of the Sahara desert, these giant tortoises are right at home in the similar environment of the Arizona desert. But like many invasive species, their introduction can pose a serious threat to native species.
 
"Due to their immense size, while defending its territory, an African spurred tortoise could easily injure a native desert tortoise," said Jones.
 
The African spurred tortoise can grow to 150 pounds, which makes it the largest mainland tortoise species in the world. By comparison, Arizona's principal native species only grows to about 15 pounds — the native species wouldn't stand a chance in a battle over territory. The African tortoise also can radically alter the landscape. This tortoise had already established itself long enough to build two burrows, including one that was 9 feet deep.
 
"When people purchase these tortoises, they are about the size of a silver dollar, yet they can grow to more than 150 pounds," Jones said. "These exotic tortoises are long-lived and because of their propensity to dig long, deep burrows, they can be extremely difficult to contain."
 
Finding just one African spurred tortoise in the Arizona wild might be strange enough, but this was the second one found this year. Officials urge that pet owners understand what they are getting themselves into when they purchase an exotic pet, and to always avoid releasing any exotic animal into a non-native habitat.

We found an African Tortoise in the street and have tried to find its owner. No luck. He's a great little guy- maybe 18" across but we really arent around alot and would love to find a home. We live in Redlands, ca. Anyone interested? 909 583 3391

We found an african tortoise behind our fence today. We are checking with neighbors to see if it belongs to them.

I'm betting non-native tortoises will have to be relocated to rescue or zoo habitats. Remaining in the desert is a really BAD idea. The quickest way to destroy the desert's natural balance is to introduce creatures like these. They are suited to the environment, yes, but they evolved somewhere else. As a result, they may be hyper-specialized. I've seen footage of a small lake that was completely overrun because some people released their unwanted goldfish. They bred so fast, they outcompeted
.... More
every other species in the lake. Soon, there wasn't enough food for them and, having no natural predators in the area, they starved to death started dying off beacuse the lake was overcrowded. Sure, we could argue that evolution is evolution. If this African tortoise is more fit, it should be the species to survive. I'd like to see that evolution at the hands of the desert itself rather than at the hands of irresponsible pet owners, thanks. I happen to LIKE our desert tortoises! I'd like to see them continue to be a successful species. They serve an ecological purpose in our food chain here. Introducing the African tortoise can only send the system farther out of whack than it already is.

If this were 1798 and you had been reading Malthus, you'd have an excuse for passing this nonsense off as analysis but anytime after the 19th century, it's just embarrassing. Goldfish being so successful that they starved to death? Is that like Yogi Berra's lament about Elaine's: "It's so crowded that no one goes there any more" ? Every predator (even herbivorous predators) becomes more populous until it reaches the limits of its food source; the mathematics of this have been understood since about 1910.
.... More
It's possible even to endanger the local population of predators this way, but it's unlikely and it's certainly not going to happen with feral pets. And did you get this notion of "the desert" being "natural" and people living near the desert being "unnatural" from Rousseau? Or is your preference for American desert tortoises over African desert tortoises just some weird displaced racism? Finally, you have the definition of "hyper-specialized" reversed. A specialize organism is *less* likely to survive in a new environment, not more likely. There might be a good reason we need to keep spurred tortoises out of our deserts, but the ones you suggest make as much sense as "they're taking our jerbs!"

must be why we see so many buffalo, wolves, and bears running around EVERYWHERE before the europeans settled here. People turn this into an "immigration" problem for animals/insects, maybe we should enclose every major city in series of domes, to keep all the "non-native" species out

Technically speaking there never were buffalo in in the United States. Only Bison. And there are lots of Bison in South Dakota and Washington/Oregon. Just sayin...

Right. They are there because the invasive species (people) brought them back from the brink of extinction.

Just the opposite: it's a reminder how if you release any exotic species, you get cool things like gigantic turtles, walking catfish, and Northern snakeheads wandering about. Life is that much more interesting.

Ok, brainchild, what part about invasive species don't you understand? Non-native invasions are never good for the local inhabitants. Just ask the Native Americans.

did you forget we migrated here too! we are an invasive species. go back far enough and nearly everything is. the earth was barren and all life began in the seas and spread. Invade is what life does. yes it causes problems but has any one ever considered that if something horrific and unspeakable were to happen. some great disaster that these new invasives would be the key to returning life to something normal. The Creator does things for a purpose including toss new life into places. Imagine how
.... More
many islands would be barren if that did not happen. imagine where you would be if Humanity never migrated for good or ill. and some of us have learned to live in the now and deal with now and not the past so kindly do not use us as a argument

Mother nature consistently creates climax ecosystems by bludgeoning the land with biological diversity. Humans, on the other hand, at least recently, create monoculture and desert by bludgeoning the land by killing all the biology. In this current Mass Extinction, perhaps the future biological diversity of the land will come from the invasives that mankind introduces to places that have been killed by mankind? Or, to put it another way, the More, the Merrier! Please introduce "invasive species" wherever
.... More
and whenever you can. A million years from now, they'll thank you.

Reading between the lines, it sounds like the future of this tortoise may be something other than the Arizona desert? Do we know his fate?

Yes, the question is what is going to be happening to him/her(?) and where is the other one found? They may have been roommates at the same place and released together. Do they have enough food where they are?
