Mangroves play an essential role in maintaining healthy life on earth, and we’ve been privileged to work in many locations where we’ve seen their impact on biodiversity levels first-hand, including India.
Frequently these ecosystems are under threat of habitat loss, whether for agricultural or land development. Thanks again to Anthropocene for adding up the facts in such clear terms.
Conservationists frequently say that ecosystems are worth more when they’re left untouched. But to whom? Local communities who could potentially farm the land might wonder, what’s the real benefit of leaving wild areas intact?
In the Bhitarkanika mangrove in Odisha, India, a group of Indian researchers grappling with this question have arrived at a surprising answer. By leaving the mangrove intact, they say, Bhitarkanika’s surrounding communities can in fact reap almost double the economic benefits they’d get from simply converting the mangrove to crops.

We have lots of reasons to believe in biodiversity, and here is one more important case in point. Thanks to Madeline K. Sofia at National Public Radio (USA) for this:
If you’re standing in the blazing sun struggling to read this on your cellphone, there may be some relief in sight.

The Cultural Heritage Center is an $8 million investment in the community. Elissa Nadworny/NPR
It is not a question I have had to ponder (the opening line of the story below) for myself, but I get it. Losing the land, through battle, through treaties that are not honored, or otherwise, is an obvious existential threat for any community, and has been since the dawn of civilization. Invisible assets such as language, like any cultural heritage, also called intangible patrimony, are less obviously existentially important. But anyone who ponders it realizes that the loss of a language or another intangible component of cultural heritage matters to all of us, not only those who are at immediate and direct risk of its extinction. In the same way biodiversity matters, so does this.
And it is an underlying logic and motivator of our initiative with Ramon tree and its role in Mayan foodways. In earlier posts on the subject that I emphasized the environmental wonder of Ramon, but it is really a cultural heritage story, still to be told at Chan Chich Lodge. Meanwhile thanks to Melissa Block at National Public Radio (USA) for this story about one communities efforts along a related path:
What does it mean to lose your land, your language, and your heritage?
For Alaska Natives, these are existential threats.
On a trip to Southeast Alaska, I traveled to one village that is finding new ways to survive: Klukwan, ancestral home of the Tlingit tribe. Continue reading

Thanks to National Public Radio (USA) and Kat Lonsdorf for a brief look into the deep work of Tim O’Hara:
Far below the surface of the ocean, off the coast of eastern Australia is an area simply known as “the abyss.” The largest and deepest habitat on the planet, the abyssal zone stretches well beyond Australia’s waters and spans half the world’s oceans — but it remains largely unexplored.

Tadarida brasiliensis by Texas Co-op Power
Chan Chich is home to an array of wildlife, and coming from Arizona, many of the tropical mammals, birds, and insects are new to me. It isn’t surprising that this lodge attracts environment-enthused guests, currently two professors who study bats. Doctors Patricia Brown and Bill Rainey were kind enough to put together a miniature lecture about their bat research for the other guests and students last night.
Throughout their research, the Doctors’ goal is to change the human perspective on the creature from Dracula-esque to eco-systemically vital. This talk couldn’t have had better timing; Emily and I found two bats near our cottage the night before and knew next to nothing about them.
Even though there are 28 species of bats in Arizona, prior to the lecture, the extent of my bat knowledge was that young Bruce Wayne developed a phobia of them after falling into a well. My understanding of the creature has now expanded to the non-fictitious. Continue reading

Thanks to Ted Williams at Cool Green Science for this story:
Stunned but delighted is how Dr. Robert McDowell, Director of Wildlife at the University of Connecticut, sounded when I arrived at his office to learn about New England cottontail rabbits.
Finally someone other than himself was interested in these vanishing natives. We pored over skulls and skins and vainly patrolled early successional woods for live specimens. McDowell seethed about the mindset of state fish and game bureaucrats: we can’t waste time on a few native rabbits when we have so many look-a-like non-natives and when license buyers want more pheasants, ducks and deer.

In our book, lost and found is normally half glass full (versus half empty) new that we enjoy sharing, and this one counts as more than half full due to the intrigue of the history and the odd charisma of the creature:
By Marguerite Holloway
On June 27, 1824, a trading vessel en route from Mauritius to England was caught in a powerful gale. For ten days, winds pounded the King George IV until it could no longer hold together. In three perilous traverses, a small rescue boat shuttled those aboard to a beach near the Cape of Good Hope. “Neither myself nor the passengers have saved a single article,” the captain later wrote. “Probably they may cast up in time.” Amid the lost cargo—mostly sugar, cotton, and cloves—were three cases of scientific specimens.

I listened to this interview while walking the trails at Chan Chich Lodge this morning, so had no photos to look at. And yet, it was vivid. And highly relevant to what we do here. I will let you listen to get what I mean.
Six photos accompany this story on the Fresh Air website, and those are curated for the podcast. If you only have time for photos click over to Paul Nicklin’s website, but the interview with him is worth every one of the 48 minutes. If you only have ten minutes to listen, go to 22:30 and if you do not find yourself bursting into a mix of laughter and other unidentified emotions, let me know; it means one of us may need some professional help:
Conservation photographer Paul Nicklen has spent more than two decades documenting the ice and wildlife in some of the most inhospitable places on Earth — the Arctic and the Antarctic. Continue reading
The United Nations Ocean Conference is underway to support the implementation of Sustainable Development Goal 14: Conserve and sustainably use the oceans, seas and marine resources for sustainable development.
The importance of collaboration between public and private sectors to brainstorm innovative solutions to environmental issues is becoming increasingly clear, as is the reality that states and local governments will be the stronger voices for climate activism.
The health of the planet and our oceans are interchangeable, and Sylvia Earle has been the spokesperson for that truth for decades.
Take the extra 18+ minutes to listen to her 2009 TED Prize Talk here.
It has been a long while since our last link to Sea Shepherd news, shame on us, but today we rectify it with news from Seth and Jocelyn’s neighborhood–actually on the Pacific side of Mexico’s Baja California Sur but as close as most people get:
Sea Shepherd’s research vessel the R/V Martin Sheen returned to Mexico’s Guadalupe Island to continue its study of Cuvier’s beaked whales, capturing never before seen drone footage of these rare and elusive cetaceans.
During the two-week expedition, Mexican lead-scientist Gustavo Cardenas Hinojosa and American collaborator Jenny Trickey, deployed various acoustic devices to compare their effectiveness. The scientists will return and leave these devices for a longer period of time. Continue reading
Market-based approaches to controlling invasive lionfish populations were highlighted at a recent GEF event in Grenada.
La Paz Group contributor Phil Karp has long been our guide into marine ecosystems, with both citizen science and social entrepreneurship posts on his work with groups in Belize and other parts of the Caribbean focused on these goals.
This collaboration with Sarah Wyatt, a colleague from the Global Environment Facility, illustrates the on-going market-based approaches to managing the invasive species while creating new cottage industry opportunities.
Seeing a lionfish while diving in the Caribbean is a cause for mixed emotions. On the one hand, one marvels at the exquisite beauty of the fishes’ flowery fins and its amazing adaptability to a range of habitats, from shallow estuaries with low salinity to deep reef environments. But then you remember that these fish don’t belong in the Caribbean, and that the very versatility noted above makes them an invasive menace. Indeed, if the fish you are looking at is a female, she may be carrying up to 30,000 eggs, and may have thirty or more native fish or crustaceans in her stomach.
One of the many impacts of the Anthropocene era on global biodiversity is the increased spread of invasive species, like the lionfish, due to rapid globalization. With the United Nations Ocean Conference taking place in New York next week, the conservation and sustainable use of the oceans and marine resources is high on the international agenda. While long recognized as an environmental and biodiversity threat, invasive species also pose a threat to livelihoods, particularly in developing countries where incomes may be heavily dependent upon a single sector or product.
Traditionally, efforts to eradicate or control invasive species have been focused on public sector interventions. But control efforts are often expensive and are either out of reach, or pose severe strains on limited budgets of developing countries. Hence there has been growing attention to identification of market-based control approaches which create commercial incentives for removing the invaders, providing a financially sustainable means of control… Continue reading
For evolutionary biology, on this platform we have favored E.O. Wilson because of his biophilia ideas (about which, plenty). For ornithology, we have leaned heavily on the Lab at Cornell and its many wonderful folks. Now, a scientist at Yale combines both of those fields and takes on the topic of beauty in a challenging manner–I am looking forward to this.
Click the book image at the left to go Indie Bound, a community of independent local bookstores, or if you need more convincing, read the beautifully illustrated Challenging Mainstream Thought About Beauty’s Big Hand in Evolution by James Gorman in the Science section of the New York Times. It is as much profile as review and asks:
Are aesthetic judgments about mates invariably tied to traits we see as adaptive and worth passing on Or, does beauty just ‘happen’?
Not long ago, a physicist at Stanford posed a rhetorical question that took me by surprise.
“Why is there so much beauty?” he asked.
Beauty was not what I was thinking the world was full of when he brought it up. The physicist, Manu Prakash, was captivated by the patterns in seawater made as starfish larvae swam about. But he did put his finger on quite a puzzle: Why is there beauty? Why is there any beauty at all? Continue reading
As Florida panthers have begun to multiply, they’ve been forced to search for new home ranges. PHOTOGRAPH COURTESY FLORIDA FISH AND WILDLIFE / FLICKR
Rewilding is a topic I started linking to as a matter of solidarity. While based in south India, I had plenty of exposure to residual evidence of the complicated–sometimes resplendently beautiful and other times brutally tragic–relationship between mankind and wild animals as played out over millennia, and still evolving. So I have kept an eye open for these stories, and have posted so many times on the topic that it might give the impression that it is a thing. As if it is happening more or better than it is really happening. But it is happening so I will keep the links coming.
Now I am in Belize most of the year, where the man-cat relationship is also millennia old, and as constant challenge as ever. But I am seeing it from well within the confines of Chan Chich Lodge and its surrounding hundreds of thousands of acres of healthy cat habitat. I know there are big cats in the USA, but not enough. That is why this story is a thrill. Dexter Filkins, never yet cited in these pages but whose reporting I depend on for other kinds of stories, was not a byline I expected to see on this story, but thanks to him for it:
For years, the Florida panther, a majestic creature that lurks in and around the forests of the ovbnm,./, has teetered on the edge of permanent disappearance. Closely related to the mountain lion, the panther once roamed across much of the South, but the ever-advancing modern world pushed it into a tiny corner of Southwest Florida. By the late nineteen-seventies, fewer than thirty survived.
Since then, the panther has been coming back, helped by a government- and privately backed expansion of its habitat. Florida panthers are now thought to number around two hundred. Indeed, there are so many big cats in the Everglades that they are venturing out in search of new territory. Continue reading
This other post today reminds me of the value of geeking out from time to time. Most of my attention to coral reef comes from Phil Karp’s posts on this platform and I admit to preferring stories featuring real people and their entrepreneurial approaches to conservation. But science is the other best friend of conservation. Today my attention is turning to coffee, in advance of the arrival this week of an intern coming from Cornell University’s College of Agriculture and Life Sciences.
Just one of the many topics for an intern, with science and research on her side, to help us tackle over the next ten weeks, bird-friendly coffee has been on been on my mind in the last year but I have been waiting for the perfect moment to focus. Nothing like the arrival of an intern to focus your mind. And so today in my task-oriented wanderings I came across this website (click the banner above), which I loved immediately for sharing this news on capsules, but the rest of the site is a great resource for present purposes as well:
A short round-up of coffee news.
Economic value of coral reefs for tourism (A). This figure summarises the combined dollar values of expenditures for on-reef and reef-adjacent tourism. Reefs without assigned tourism value are grey; all other reefs present values binned into quintiles. Lower panels show Kenya and Tanzania (B), South-central Indonesia (C), and Northern Caribbean, with part of Florida, Cuba and the Bahamas (D). (Further maps can be seen in Appendix A and online at maps.oceanwealth.org
A country that depends on its coral reef to attract visitors, as Belize does, has every reason to pay attention to the various sciences paying attention to those reefs. Mostly marine biologists, perhaps, but also economists. Geeks and wonks are heroically gathering information, processing it, publishing it and if not for The Nature Conservancy’s efforts some of us might not ever see it.
The August, 2017 issue of Marine Policy, an academic journal, carries the article “Mapping the global value and distribution of coral reef tourism” by the scientists Mark Spalding, Lauretta Burke, Spencer A. Wood, Joscelyne Ashpole, James Hutchison, and Philine zu Ermgassen and TNC’s Cool Green Science has a summary in common language. Also they complement the academic illustration above with one of their own:
If it’s true that people reveal their true values by how they spend their money, coral reefs are very valuable indeed. In fact, according to a new study in the Journal Marine Policy coral reef tourism generates $36 billion (U.S) in global value every year. Continue reading

Sometimes, sitting in a glass house, reading the news makes me want to throw a stone. The glass house where I live includes a farm in an extremely biodiverse area. It is surrounded by nearly half a million acres where logging happens. But there is farming, as you can read about in the news below, and there are plenty of better ways of farming; there are loggers like those in the news below, and there are forests where extraction happens according to standards such as those set and enforced by the Forest Stewardship Council.
Instead of throwing a stone, I get up every day and make sure the glass around here is as transparent as possible, because we can demonstrate a better way of supplying food, of harvesting wood, and doing so with the protection of wildlife in constant view. Meanwhile, I do read the news from elsewhere and continue to share it here (thanks to the Guardian’s Jonathan Watts in Vila Bela da Santíssima Trindade for this one):
