Crews at a nuclear plant south of Miami spend summer nights walking gravel berms with headlamps and mesh bags.<\/p>\n
They are picking up newborn crocodiles, weighing them, clipping a tag and putting them back in the water.<\/p>\n
This past season they handled 606 hatchlings<\/strong>, out of roughly thirty nests.<\/p>\n In 47 years of doing this, the count had never passed 600<\/strong>.<\/p>\n And the habitat producing them was designed for cooling water<\/strong>, by engineers who were not thinking about reptiles.<\/p>\n The work is unglamorous and it happens in the dark, because that is when hatchlings move.<\/p>\n A staff biologist at the plant leads the collection, and the animals are measured, marked and released back into the same canal system.<\/p>\n Roughly thirty nests produced the total, which works out to about twenty<\/strong> surviving hatchlings apiece at collection.<\/p>\n The program has run without a break since the first clutch was found on the property in 1978.<\/p>\n Nothing about the method has changed much either, because a hatchling still has to be picked up by hand to be counted.<\/p>\n Across those decades it has tagged more than 10,000<\/strong> young animals, which is the number that makes the record legible.<\/p>\n Without the earlier counts, 606 is just a figure. With them, it is the first time the site has cleared six hundred in almost half a century<\/strong>.<\/p>\n The American crocodile in the United States came close to disappearing entirely.<\/p>\n By the middle of the 1970s the estimate was around 200 animals<\/strong>, squeezed into the Florida Keys and the southern end of Biscayne Bay.<\/p>\n It went onto the federal endangered list in 1975, at a point when nobody was confident the species had a future in the country at all.<\/p>\n Shoreline building had taken most of the nesting ground, and what was left sat in exactly the places people wanted to be.<\/p>\n The recovery took three decades and it was slow the whole way<\/strong>.<\/p>\n The status was lowered from endangered to threatened in 2007, which is the formal marker that the trend had reversed.<\/p>\n State biologists now put the Florida population at at least 2,000<\/strong>, and that figure is a floor rather than a ceiling.<\/p>\n The canals were approved in 1971 and running by 1973, and the reason was heat.<\/p>\n Rather than send warm water out into the bay, the plant sends it into a closed loop<\/strong> that runs two miles wide and five miles long.<\/p>\n That is 32 canals flowing south, seven flowing back north, and about 5,900 acres<\/strong> of ground given over to the arrangement.<\/p>\n Digging them produced long berms of dry raised fill running for miles, which is exactly what a female crocodile looks for when she needs somewhere to nest.<\/p>\n She needs ground that stays above the water line through the whole incubation, and that is harder to find in south Florida than it sounds.<\/p>\n The water beside those berms is warm and salty, which is exactly what the hatchlings want.<\/p>\n And the whole site is fenced, patrolled and closed to boats, which removes the pressure that kept the numbers down<\/strong> everywhere else.<\/p>\n This is where the story usually gets stretched, so it is worth being exact.<\/p>\n The operator puts 300 to 400<\/strong> crocodiles in and around the canal system on an average day, as the utility<\/a> states.<\/p>\n Against a statewide floor of two thousand, that is roughly one animal in six, not the quarter that gets repeated.<\/p>\n What is genuinely exceptional is the concentration. The site holds the highest density<\/strong> of crocodiles anywhere in North America, as the account<\/a> of this season describes.<\/p>\n It is also one of only three primary nesting populations left in the country, which makes the site structurally important rather than simply crowded.<\/p>\n The same accidental logic shows up at an offshore array<\/a> and a fenced solar site<\/a>, where the fence itself<\/strong> does most of the conservation work.<\/p>\n None of this makes the canal system a nature reserve, and nobody involved describes it that way.<\/p>\n Water that sits and evaporates in a loop gets saltier than the sea<\/strong>, so salinity there is monitored continuously and has been for years.<\/p>\n The habitat is a byproduct. It was not planned, it is not permanent, and it depends on the plant continuing to operate.<\/p>\n What the record does prove is narrower and rather more useful than a feel good story about nature bouncing back.<\/p>\n An animal down to two hundred individuals did not need pristine wilderness<\/strong> to come back.<\/p>\n It needed warm water, dry ground to dig in, and nobody bothering it<\/strong> for fifty years.<\/p>\n","protected":false},"excerpt":{"rendered":" Crews at a nuclear plant south of Miami spend summer nights walking gravel berms with headlamps and mesh bags.
