Santa Cruz – Tortoises and Tortuga Bay

Last time, we did some adventuring around Santa Cruz Island. We visited some spots downtown and checked out Las Grietas (aka the best snorkeling spot), Los Gemelos lava craters, and the lava tubes of El Chato Tortoise Reserve.

There are a few tortoise reserves on Santa Cruz, and I told our taxi driver, Fredy, to take his pick and that we’d be happy as long as there were lava tubes and tortoises. So, we ended up at El Chato. These reserves are different from the conservation centers because they’re privately owned, and the tortoises are technically wild! They’re there because it’s a good habitat, not because they can’t leave. It was weird to see them in the “wild”… we even saw a tortoise crossing the main road! (That sounds like the beginning of a bad joke.) It was a strange sight after only seeing them in captivity to that point. At least with tortoises, unlike with deer, you don’t have to worry about them speedily darting out in front of your car!

Anyway, El Chato used to be a cattle ranch, but around 20 years ago, the owners started working to return the land from farmland to a natural habitat for tortoises, changing the farmland vegetation to native vegetation. This transition naturally brought tortoises back to the land. Now, it’s a lush, green forest and is really beautiful! Besides the vegetation, there are also a bunch of muddy pools that tortoises love. They sometimes spend multiple days hanging out in them, likely to help regulate their body temperatures and maybe to also kill ticks and protect from mosquitos.

I’ve talked a little bit about tortoises in previous posts, but later in our trip, my aunt and I visited the Charles Darwin Research Center, also on Santa Cruz, and learned a lot about the Galapagos tortoises in general. There were originally fifteen distinct Galapagos tortoise species from ten different islands. Now, unfortunately, only eleven species remain, due mostly to human interference and the thousands and thousands of tortoises that were killed for food and oil back in the whaling days.

The Darwin Center is a research hub that monitors the wildlife of the islands and works to minimize damage and neutralize threats. The Center is involved with all sorts of conservation projects, and as part of their tortoise research, they’ve identified genes from two of the extinct species, the Pinta and Floreana, in some living tortoises! The hope is that it may be possible to essentially recreate those species through careful breeding. It sounds insane but also kind of amazing!

The tortoise species fit into two major categories: dome-shell tortoises, and saddleback tortoises. The Santa Cruz tortoises have dome shells. These are typical of tortoises that live in wet zones and where food is plentiful close to the ground. As you’ve seen from the pictures, that’s definitely true of the Santa Cruz highlands! In drier places with less vegetation, the tortoises had to adapt to survive. Saddleback tortoises have shells that allow a wider range of vertical motion which allows them to reach food higher off the ground. It’s so cool to see such a clear example of how different habitats impact how species develop!

I was surprised to learn that most Santa Cruz tortoises are migratory. It seems crazy for that to be the case for such a slow-moving animal! They move anywhere from about 65-2,300 ft (20-700 m) each day, and they travel up to 6mi (10km) from the coastal areas to the highlands during the rainy season. Tracking has shown that while most migrate (and move back and forth between two general areas), some of them seem almost nomadic, wandering here and there without any clear rhyme or reason. One aspect of the tortoise conservation work in Santa Cruz has been educating the locals about these migrations and asking farmers to use raised barbed wire fences so that tortoises can freely move about.

In case you’re wondering how quickly that distance is covered…

The answer is, “Not very.”

This balance between allowing people to live their lives vs. conserving wildlife is complicated. Some people think no humans should live in the Galapagos or even visit. Others think that people should be able to do whatever they want. Neither of these extremes is likely, so the question then becomes, “How can we best serve both interests?” It’s like a case study in compromise, and I think it’s something we can all probably learn from. Don’t get me wrong, the situation is far from resolved. But people are paying attention and trying to figure it out, and I think that’s worth something!

The tortoise reserve was our last stop for the day, so we headed back into town when we were finished. Everyone was pretty exhausted!

The next day, we had time for one more adventure before we had to catch our ferry to Isabela Island. We decided to check out Tortuga Bay, aka the MOST BEAUTIFUL BEACH IN THE WORLD. Yes, another one of those. Like I’ve said, I’m not a great judge of beaches, but this one was definitely memorable.

We walked from our hotel all the way to the beach, first walking about seven blocks to the start of the trail, and then walking another half hour/45 minutes on a shade-less trail to get to the bay.

The scenery along the way isn’t especially exciting, but I was fascinated by these cactuses with trunks that look like cartoon tree trunks. They’re in the opuntia cactus family, or “prickly pear”, and while many varieties exist, the Galapagos opuntias are endemic (they only exist there) and are the only ones that grow like trees! The tallest opuntia are found on Santa Cruz where they can grow up to 40ft (12m) tall! That’s crazy, in case you didn’t know.
