“Doc” Ehrhart wasn’t afraid to get his arms soiled — or bitten — or stung — or wrapped round an ornery rattlesnake.
He’d usually joke: “ “I’m not any good with computer systems, however should you ever want somebody to free-hand a rattlesnake, or pores and skin a skunk with out puncturing the scent gland… I’m your man.’ “
But it surely was the mysterious, large mild turtles nesting close to NASA’s Cape Canaveral launch pads that almost all peaked Llew “Doc” Ehrhart’s curious nature and captured his creativeness as a younger scientist within the Nineteen Seventies.
Identified internationally for his long-term sea turtle analysis and advocacy, Llewellyn (Llew) Ehrhart Jr., “Doc” as most knew him, died at his Oviedo dwelling on March 3. He was 79.
He was preceded in loss of life by his beloved spouse of 53 years, Carol. He’s survived by his twin daughters, Ashley Ehrhart, of Oviedo, and Samantha “Mandy” Silver (husband Andrew), of Winter Springs.
In a life spent digging in the dunes, the eggs that Ehrhart unearthed revealed deeper truths in regards to the threatened and endangered sea turtles that start their journeys right here, extra so than anyplace else on Earth. They had been his ardour, his life’s journey, and his mission to save lots of.
The professor emeritus at College of Central Florida would have turned 80 on April 22 — Earth Day, a becoming birthday in accordance those that knew him and see his legacy as unparalleled in sea turtle conservation biology.
A naturalist of the old-school selection, Ehrhart’s unprecedented information proved that sea turtles nest on the House Coast like nowhere else. He pieced collectively groundbreaking analysis into what number of sea turtles nest alongside the Brevard County and Indian River County shoreline and why, laying the scientific groundwork that led to institution of the Archie Carr Nationwide Wildlife Refuge in 1991.
Many take into account the refuge, which spans 20.5 miles from Melbourne Seaside to Wabasso Seaside alongside Florida’s east coast, as his biggest achievement. But it surely was the scholars he mentored who rose the ranks of sea turtle conservation biology that “Doc” and numerous others take into account his biggest legacy.
His footprints stretched far and broad alongside japanese Florida’s seashores, however the imprint on these he mentored went a lot deeper and wider.
“Dad was so proud, he actually thought-about amongst his biggest accomplishments all of the individuals he taught,” his daughter, Ashley Ehrhart, of Oviedo, mentioned. “He wasn’t like a giant political man, however he was instrumental,” she mentioned of his function in establishing the Carr refuge.
Small-town Pennsylvania boy turns into big-time biologist
Born April 22, 1942 in Dallastown, a central Pennsylvania city with a inhabitants of about 3,000.
A son of small-town grocery retailer house owners, Doc met Carol at church camp after they had been 13 years previous, and so they married upon his commencement from Franklin & Marshall Faculty in Central Pennsylvania.
They then moved to Ithaca, New York, the place Doc pursued his PhD in zoology at Cornell College.
He’d make quite a few journeys to Florida. His dissertation centered on Florida mice. Doc would carry mice again to Ithaca in shoe containers for his research, as was frequent within the ’60s.
As he neared commencement, a buddy known as to see if he was able as a mammologist at a brand new college in Orlando. He took the job at Florida Technological College, which might grow to be UCF, a 12 months after it opened its doorways in 1968.
However Doc’s conservation journey started in earnest within the early Nineteen Seventies at NASA’s Kennedy House Heart, trying to find skunks, shrews, mice and different small mammals the place the house company had deliberate to pave the House Shuttle touchdown strip. In 1972, he acquired NASA funding to check vertebrate ecology at KSC. He lured a fellow graduate scholar from Cornell, Franklin “Buck” Snelson, whose doctoral analysis centered on fish, to hitch him on the school at FTU and on the KSC analysis.
No creature was too small, no activity too small, or too large.
Whereas his most important job was live-trapping rats and different vermin close to KSC’s two most important launch pads, the unusual huge-shelled creatures on the seaside quickly caught his curious eye. Sooner or later in 1973, whereas on the headquarters of the Merritt Island Nationwide Wildlife Refuge, the refuge biologist, Jim Baker, instructed Doc he’d seen sea turtles nesting out on KSC’s seaside.
To Ehrhart’s shock, nobody was learning sea turtle nesting on NASA’s property. Nearly nothing was recognized about their behaviors.
So he and his college students started gathering information about sea turtle nesting habits, monitoring nests late at night time and on the daybreak to keep away from the most popular elements of summer time days in Brevard, identical to nesting and hatching turtles do.
“It is onerous work,” Ann Marie Lauritsen, a biologist with U.S. Fish and Wildlife Service in Falls Church, Virginia, recollects of her days as Ehrhart’s college students within the late Nineteen Nineties and early 2000s. She’d later grow to be southeast sea turtle coordinator for USFWS, and now’s within the company’s division of worldwide affairs.
“It was not straightforward, but it surely was simply immersing ourselves within the biology of turtles and really understanding the species and creating a way of awe,” Lauritsen recollects of Ehrhart infectious enthusiasm. ” ‘Doc’ was pivotal when it comes to inspiring curiosity in regards to the species and an curiosity in studying extra. He did that for all of his college students that labored for him.”
That enthusiasm by no means waned. He was going out netting turtles proper earlier than COVID, she added.
“It was about getting on the market and seeing the species,” Lauritsen mentioned. “He actually reached everybody the place they had been. His footprints prolonged extensively.”
Doc’s information would show that feminine sea turtles return to their their natal seashores to nest, highlighting the urgency of defending these seashores.
His staff tagged one leatherback sea turtle named “China Lady” in 1994, for instance, and the turtle returned each two to 3 years to nest within the Archie Carr Refuge for greater than 20 years.
Doc was additionally the primary to web juvenile inexperienced sea turtles within the Indian River Lagoon, for long-term catch-release analysis. These research found inexperienced turtles within the lagoon weighing as much as 130 kilos and lots of with odd tumors attributable to viral infections.
From Canaveral Nationwide Seashore to Melbourne Seaside
Ehrhart’s analysis started to shift southward, to the realm that is now the Carr refuge, after an bold graduate scholar in his group, Paul Raymond, discovered a strategy to fund his Grasp’s diploma analysis by shifting south to Brevard County the place officers needed to perceive the affect of seaside renourishment on sea turtle nesting.
Raymond was seeing extra turtles there in a single night time than in a month within the space round KSC.
The long-term analysis Ehrhart’s group would show the 20-mile stretch of seaside South Brevard had the densest sea turtle nesting for inexperienced turtles within the western hemisphere.
He and his college students would additionally make clear how seaside lights disoriented numerous sea turtle hatchlings, resulting in Brevard County in 1985 enacting the state’s first ordinance to restrict seaside lighting throughout turtle nesting season.
His science quickly confirmed the inexperienced sea turtle was to date gone in Florida, he feared they’d by no means bounce again. He knew it was doable, although, and in the end helped make it occur. Greens grew again like compound curiosity.
“He known as that among the many biggest conservation success tales ever,” Ashley Ehrhart mentioned.
Piecing collectively Carr refuge
As a younger director of Brevard’s new Environmentally Endangered Lands Program within the early Nineteen Nineties, Duane DeFreese labored with Doc to piece collectively the lands that authorities would purchase for the Carr refuge.
Doc’s enthusiasm for scientific discipline work was infectious, mentioned DeFreese, now government director of the Indian River Lagoon Nationwide Estuary Program. “I feel that’s the reason so lots of his college students stayed within the profession path.”
Blair Witherington was amongst these college students.
As an undergrad at UCF, Witherington was extra concerned with fish, however he quickly would catch Doc’s infectious enthusiasm for turtles. Witherington would go on to earn a PhD, work for the Florida Fish and Wildlife Analysis Institute and grow to be an adjunct assistant professor on the College of Florida.
“‘Doc had the large image in thoughts,” Witherington mentioned of his turtle analysis. “He instructed their story. They’re fascinating animals. They had been obscure to some extent. It is onerous to like them until you already know them.”
Doc’s analysis helped show that sea turtle nesting on the Carr refuge mirrored nesting statewide, Witherington mentioned.
Barbara Schroeder, nationwide sea turtle coordinator for NOAA Fisheries, is among the many many college students impressed by Ehrhart’s enthusiasm for “every part round us within the pure world.”
“I feel that legacy will stay on,” Schroeder mentioned. “He was simply such a pleasure to be out within the discipline with. Anytime you are working within the discipline you are topic to no matter comes your manner. He by no means panicked about something. He was very measured and calm. Regardless that he was an enormous in the ocean turtle world, he at all times had time for any scholar.”
“He was a unprecedented man and a unprecedented buddy,” DeFreese mentioned. “His sneakers won’t ever be stuffed.”
End up your seaside lights
Beachside properties and companies should end up or shade their lights throughout sea turtle nesting season, which runs from Sea turtle nesting season formally begins March 1 for the Atlantic coast of Florida. Brevard County has a “lights-out” ordinance efficient Might 1 to Oct. 31 that requires all lights seen from the seaside to be both coated, blocked, moved, or turned off from 9 p.m. to five a.m. This contains flashlights, cellphones, and crimson lights. Though sea turtles are much less affected by crimson mild, they do nonetheless see it.
