Thomas Lovejoy, a prominent biologist for major conservation groups who spent decades on an
expansive, ongoing project in Brazil to preserve the Amazon rain forest, died on Saturday at his
home in McLean, Va. He was 80.

The cause was pancreatic neuroendocrine tumors, his daughter Elizabeth Lovejoy said.

Dr. Lovejoy “was a historic figure,” said Russell Mittermeier, the chief conservation officer of
Re:wild, a conservation organization.

“He really put the Amazon, and in particular Amazonia, on the international conservation map,”
Dr. Mittermeier added, referring to the vast area of rain forests on South America. “When the
whole conservation business started in the ’60s and ’70s, there was little focus on South America.
But Tom changed that.”
Dr. Lovejoy’s field research in the Amazon was the centerpiece of a broad career dedicated to
ecology. He invented “debt for nature” swaps, which let countries trade forgiveness of a portion of
their foreign debt for their investments in conservation. He published an early projection of
extinction rates, was a creator of the public television series “Nature” and popularized the term
“biological diversity,” later shortened to biodiversity.

Dr. Lovejoy long ago called for the preservation of biologically diverse ecosystems that store
carbon to help fight climate change, but deforestation has continued to erode Amazonian rain
forests. In an essay last month in The New York Times, he and John Reid, an economist who helps
Indigenous peoples protect their territories, wrote: “Forests continue to disappear — cut and
burned into ever smaller patches. This failure challenges all of our climate efforts because unless
forests remain standing, the world will never contain global warming.”

Dr. Lovejoy spent more than 40 years on his ecological work in the Amazon. Since 1979, his
Biological Dynamics of Forest Fragments Project has tested whether birds, mammals, insects and
trees survive in patches of rain forest cut off by roads, development or agriculture. Dr. Lovejoy and
his team documented the species in parcels ranging in size from one to 100 hectares near Manaus,
Brazil, to see if they could survive being cut off from intact larger forests, and what happens to
those exposed to heat on the perimeters of the land.

Some rodents, certain frogs and light-loving butterflies were found to have survived well in the
fragments but mammals and some birds with large ranges suffered, according to an article in 2011
in Mongabay, a nonprofit environmental science and conservation news website.

“Fragments lose up to 30 percent of their biomass, essentially forever, because of the vulnerability
of big trees to windthrow,” Dr. Lovejoy told Mongabay, referring to the felling or breaking of trees
by wind. He added, “Hundred-hectare fragments lose half of the forest interior bird species in less
than 15 years.”

Dr. Lovejoy set up a research facility, Camp 41, near Manaus, for scientists attracted by the allure
of the immense tropical wilderness. Its tin-roofed structures are the base not only for working
ecologists but also for the prominent people Dr. Lovejoy invited to witness the deforestation and to
recruit as potential allies in preservation. They included donors, politicians (Senators John Heinz,
Tim Wirth and Bill Bradley), celebrities (Tom Cruise, Olivia Newton-John and the novelist Peter
Benchley) and media elite (the newsmen Tom Brokaw, Ben Bradlee and Walter Cronkite).

“We went to his site, clambered over miles of tree trunks, spent time in the forest with jaguars, ate
dry cheese and water for dinner and slept in hammocks,” Paul R. Ehrlich, professor emeritus of
population studies at Stanford University and the author of “The Population Bomb” (1968), said in
a phone interview.

In a statement after Dr. Lovejoy’s death, Mr. Wirth recalled exploring the rain forest by day and
sleeping to “the sounds of howler monkeys and the snoring of Al Gore, Jack Heinz, Ben Bradlee
and Peter Benchley, packed together side by side, bumping up against each other in swinging
hammocks.”

Dr. Lovejoy was known as a charming host and created a congenial atmosphere for his guests in
the Amazon, but his intentions were deadly serious. If more deforestation occurs, the impact on
the rain forest’s hydrological cycle — and the planet — would be dire, he warned.

“It’s really part of the continental climate system,” he told The Christian Science Monitor in 2018.
“And that’s not a very sensible thing to mess around with.”
 “Hundreds of thousands of species,” Dr. Lovejoy once
wrote, “will be irretrievably lost as their habitats
vanish, especially in tropical forests.”

Thomas Eugene Lovejoy III was born on Aug. 22, 1941, in Manhattan. His father, Thomas Jr., was
the president of the Manhattan Life Insurance Company (as was his grandfather, who in 1912 led a
group that acquired control of it), and his mother, Jeanne (Gillette) Lovejoy, was a homemaker.
(As an adult, Dr. Lovejoy would serve as a director and chairman of Manhattan Life.)

An only child, he loved the outdoors and reading (his family did not have a television). He attended
the Millbrook School in Dutchess County, N.Y., about 90 miles north of Manhattan, because it had
a zoo that nurtured what he called the “beautiful and intellectual attraction” of living things.

He studied biology at Yale, where he was a zoological assistant at the Peabody Museum of Natural
History. He took a year off to study in the Nile River region of Nubia, and graduated with a
bachelor’s degree in 1964. While working toward his Ph.D in biology at Yale, he spent a summer
studying migratory birds in the Amazon; his dissertation was on the diversity of birds in the rain
forest.

“The Amazon basin at the time was a mostly trackless virgin forest,” Dr. Lovejoy said in an
interview in 2012 when he received the Blue Planet Prize from the Asahi Glass Foundation for his
environmental research. “It was like a dream world for any biologist because there was only one
road in the entire area, which had a population of three million.”

Much of his research in the Amazon occurred while he held positions at four organizations, all of
which understood that he would need time for his research and would not be a full-time employee.
He spent 14 years at the World Wildlife Fund in the United States (he was its 13th employee),
rising to executive vice president from 1985 to 1987, and was the assistant secretary for
environmental and external affairs at the Smithsonian Institution from 1987 to 1994. He was a
senior scientist when he left the Smithsonian in 2001.

At the World Bank, he was the chief biodiversity officer from 1999 to 2002. At the H. John Heinz
III Center for Science, Economics and the Environment, he was president and, later, the
biodiversity chair, from 2002 to 2013.
During his time at the World Wildlife Fund, he wrote a section of a report commissioned by
President Jimmy Carter — “Global 2000: Entering the 21st Century,” released in 1980 — in which
he projected that 20 percent of all species on earth would be extinct by 2020.

“Hundreds of thousands of species,” he wrote, “will be irretrievably lost as their habitats vanish,
especially in tropical forests.” Looking back 32 years later in the Blue Planet interview, he said,
“My projection was not far from the mark.”

He later wrote two papers using a new term: “biological diversity.”

In 1984, he proposed the debt-for-nature swaps as a mechanism to keep developing countries from
having to slash their conservation budgets to pay off debt. Such swaps, he wrote in an opinion
column for The Times, “would be far more than a disinterested handout to mendicants: Left
untouched, the environmental problems of the third world inevitably will touch our lives by
generating social and political unrest.”

In addition to his field research and executive positions, Dr. Lovejoy served on scientific advisory
councils in the administrations of Presidents Ronald Reagan, George H.W. Bush and Bill Clinton.
In 2010, he became a professor in George Mason University’s department of environmental
science and policy, teaching a course in the challenge of biodiversity.

In addition to his daughter Elizabeth, known as Betsy, he is survived by two other daughters,
Katherine Petty and Anne Jenkins, and six grandchildren. His marriage to Charlotte Seymour
ended in divorce.

Camp 41 was not the only site that Dr. Lovejoy used to bring disparate people together; he also
hosted them at his home in McLean, a log cabin called Drover’s Rest, for dinners and fine wine.

“There was always an element of a higher purpose” at such gatherings, said Jane Lubchenco, a
marine ecologist who is deputy director for climate and environment in the White House’s office of
science and technology policy. “He brought people together to build connections in a way that
might lead to more conservation action.”
