I’ve been very fortunate in having spent many years working with Crocodilians in both captivity and the wild while remaining (more or less!) intact in the process.  Today I’d like to introduce the Marsh Crocodile (Crocodylus palustris) and highlight a unique population that thrives in a most unexpected locale.

Threats

Marsh Crocodiles, also known as Muggars, are equipped with immensely broad snouts (the croc world’s widest) and may reach 16 feet in length.  Their large size and propensity to colonize canals and other man-made water bodies renders them a threat to people in some areas. Attacks are not unknown – this, along with a fondness for livestock and commercially important fish, has doomed several populations to extinction.  Read More »

The term “Asian Turtle Crisis” was coined in 1997, when photos of thousands of rare turtles being slaughtered in a Guangzhou, China food market propelled the tragic plight of Asia’s freshwater turtles into the conservation spotlight.  The private turtle-keeping and zoo communities were quick to take action, and a number of fine organizations and programs resulted.  In 2001, I traveled to south Florida to help rehabilitate and place 7,500-10,000 turtles that had been confiscated in China.

Hard Work Pays Off

In south Florida I worked day and night alongside dedicated folks from the New York Turtle and Tortoise Society and other herp-oriented organizations, internationally-known turtle biologists, private turtle fanciers and zoo colleagues.  The marathon effort was a grand success, with more turtles saved and placed in good homes than anyone would have dared hope upon first seeing their wretched condition.  Given the passion, funds and other support that the situation aroused, the future looked promising.  Unfortunately, 9 years later, the situation remains very bleak.

90+ Species Face Extinction

Recent studies by Conservation International (please see this article) reveal that at least 1/3 of the world’s 280 turtle species, including most of those found in Southeast Asia, are in imminent danger of extinction.  Two photos on the homepage of the NY Turtle and Tortoise Society, taken 12 years apart in Guangzhou, China food markets, illustrate, graphically and tragically, that little has changed.

Several turtle species are represented by single populations numbering 12-50 individuals; only 4 specimens of the Red River Giant Softshell (Rafetus swinhoei, please see photo) are known to exist, the status of many Asian Box Turtles (Cuora spp., please see photo) can not even be determined, but several species have not been seen in years…the list goes on.

In Part 2 of this article we’ll take a look at the causes of the recent catastrophic declines in turtle populations and what is being done to reverse the trend.

I have belonged to local herpetological societies since childhood, and continue to be involved with several today.  A few, such as the NY Turtle and Tortoise Society, nicely serve both professional herpetologists and lay people…but whatever their leanings, all are of immense value.  Today I’d like to highlight some professional groups and journals that are open to everyone.

The Bronx Zoo’s Reptile House has copies of the “Big Three” – The Journal of Herpetology, Copeia and Herpetologica – dating back to the first issues of each, and in my 21 years working there I think I went through most of them!  Membership tends to be expensive (student rates are often available), so I summarize research notes from current issues and post them here on occasion (please see articles below).  Read More »

Studies in several countries recently hinted that snakes may be declining worldwide, in much the same manner as has been shown for scores of amphibian species (please see article below).  This month (October, 2010), scientists at the University of Arizona have documented massive declines in both snakes and lizards in a well-protected reserve, adding to fears that major extinctions lie ahead.

Frightening Similarity to Earlier Studies

Populations of 8 snake and 6 lizard species in Arizona’s Organ Pipe National Park were found to have declined by 50% between 1998 and 2002, and have not recovered.  The reptiles in question had been monitored carefully for 22 years, so accurate baseline numbers were available.  The species that showed significant declines included Regal Horned, Zebra-Tailed and Red-Back Whiptail Lizards, Mojave and Western Diamondback Rattlesnakes, Gopher Snakes and King Snakes.
