Reptile conservation efforts address the loss of natural habitat and declining numbers of certain species. Conservation groups work to bring attention to the issue through education, protection or restoration of habitat, and legislation that supports reptile conservation. These groups typically use scientific research to identify how certain reptiles become endangered or threatened and look for solutions to protect turtles and tortoises, snakes and lizards, and crocodiles and alligators.

The declining numbers of sea turtles prompted international treaties to protect survival of these creatures. Pollution, especially from plastic waste, and capture for commercial use pose threats to sea turtles worldwide. Some sea turtles die when they become accidentally trapped in commercial fishing nets. Conservation programs also address human destruction of beach nesting sites.

Reptile Conservation International, a nonprofit organization, promotes the application of synthetic hormones to turtle eggs to produce more females. Researchers discovered topical applications of estrogen could override the natural process that determines the sex of turtles during the incubation period. The temperature of eggs in the late stage of development determines the sex, and manipulation of this process might replenish endangered species.

Experiments on two kinds of sea turtles, freshwater turtles, farmed crocodiles, and geckos showed this patented method created no adverse effects on a female’s ability to reproduce at maturity. The reptile conservation group considers hormone application a cost-effective way to address endangered reptiles, reporting $20 US Dollars (USD) can treat approximately 250,000 eggs. This method might replace the task of digging up turtle eggs and moving them to an offsite incubation facility, a process that typically produces a higher number of males and poses difficulty in remote areas.

Habitat protection represents another goal of reptile conservation programs. Natural habitats might become contaminated by pollution or destroyed by urban growth. The desert tortoise might be affected by off-road vehicles, ranching or agricultural expansion, and development of alternative energy sources. Conservation groups commonly work with private land owners and public agencies to protect and restore these areas.

Educational components of reptile conservation typically include information to dispel myths about certain species, especially crocodiles, alligators, and snakes. Conservation groups commonly explain the importance of each species to the ecosystem and urge citizens to support preservation efforts. These groups might also work with landowners to preserve threatened habitat.

Reptile conservation might involve ecotourism, one of the fastest-growing industries worldwide. It addresses the fine balance between preserving the economic benefits of tourism with potential harm to the environment. Many ecotourism activities incorporate educational campaigns into the overall experience of viewing reptiles in the wild.

@pastanaga - The sad thing is that turtles are keystone species that affect many other sea creatures we rely on for food. If they disappear, so will a lot of other species.

And that's true for a lot of reptiles. They are such quiet and shy creatures most of the time we don't even notice them, but if snakes, for example, were to disappear, we'd quickly notice the difference in the numbers of rodents in our houses.

@irontoenail - One of the advantages of this is that scientists can artificially affect incubation to manipulate the gender ratio, as it says in the article, so there is hope yet for endangered reptile species. One of the things that is more difficult to overcome in the wild is the fact that young reptiles are so vulnerable and often take years to come to maturity.

Sea turtles are a classic example. They can take decades to reach the point where they will mate and lay eggs and very few will live to the point where they can do that. Even though it's becoming more common for them to be protected after they hatch, they still have to spend years in the ocean where they could be eaten at any moment. And that's not even getting into the fact that adult turtles are often victims of pollution or illegal hunting.

I remember hearing about how the lack of females is a big problem in a lot of reptile species. Komodo dragons, for example, are thought to only have a few hundred breeding females left in the wild, even though there are several thousand adults in general.

And since male and female numbers are affected by the environment during egg incubation for a lot of reptiles, this is probably going to become more and more of an issue as climate change becomes more severe.
