Is their success sustainable?
The land on the Padres Mesa Demonstration Ranch, in northeastern Arizona, stretched so vast and wild that it could be perspective-skewing, easy to get lost in. But Bill Inman effortlessly navigated his truck through a sea of blue grama grass, broom weed and sage. When he spotted a herd of cows, he hit the brakes.
“She’s a box of chocolates,” Kimberly Yazzie said as she pointed at a stately heifer.
About a dozen cows with week-old calves were bedded down in late winter forage, all muted greens and gold. Continue reading
Although we’ve highlighted citizen science so many times on these pages, it never occurred to me that some of these projects have spanned nearly 9 decades.This particular project’s device is called a continuous plankton recorder (CPR). An apt acronym, indeed.
Since 1931 ‘citizen scientists’ on ships have enabled data collection on the tiny building blocks of the sea. Now this research could shape how we tackle the climate crisis
On a clear day, from their small, unassuming warehouse on the south Devon coast, Lance Gregory and Dave Wilson can see right across Plymouth Sound to the Eddystone lighthouse. Today, they’re watching a ferry from Brittany, the Armorique, pull into dock.
Behind it, the ferry is towing a one-metre-long device shaped like a torpedo. It doesn’t look like much, but it’s part of the planet’s longest-running global marine survey.
The device is called a continuous plankton recorder (CPR), and it’s one of 53 such devices that Gregory and Wilson manoeuvre using forklifts in their warehouse, surrounded by racks of distinctive yellow boxes and clipboards covered in spreadsheets.
They dispatch these CPRs in bright yellow boxes to “ships of opportunity” – ferries, cargo or container vessels that have agreed to volunteer for the mission. Once a ship leaves port, the crew attach the device to the stern using steel wire, then toss it overboard.
Trailing along behind the ship, it collects data for the CPR survey. The mission is vast but the subject is minuscule: plankton, the tiny organisms that drift in the ocean. Every marine ecosystem relies on plankton for its basic food source, and it generates half the oxygen we breathe. Perhaps more than any other organism, it is crucial to all life on our planet.
The CPR survey is the longest-running marine science project of its kind. It began in 1931 when the scientist Sir Alister Hardy investigated how herring were influenced by plankton in the North Sea. This month the distance surveyed will reach an impressive 7m nautical miles, equivalent to 320 circumnavigations of the Earth.
Since that first tow from Hull to Germany 89 years ago, the equipment has hardly changed. So far a quarter of a million samples have been analysed, representing a vast geographical spread over the course of the past century. The immense scope has allowed scientists to see dramatic patterns in ocean health, across both time and space, building a much clearer picture of how our marine environments are changing.
It is also, says Gregory, “one of the oldest citizen science projects in the world”. Continue reading
Migration, an ageless natural phenomenon, can be all the more spectacular when we remove its constraints:
Along central Maine’s Sebasticook River, the first thing you’ll notice are the birds. Eagles are everywhere, wading on gravel bars and chattering from the trees.
“A whole bunch of birds, they’re bald eagles, those are all bald eagles!” says conservationist Steve Brooke.
It’s a dramatic sight, as the bald eagles swoop to catch fish from the river. And it’s a sight that Brooke predicted for this region, more than 20 years ago. That’s when he began advocating for the removal of a large hydroelectric dam downstream, on the Kennebec River. The Edwards Dam came down in 1999 after the federal government ordered its removal, saying the ecological costs outweighed the benefit of the power it provided. Continue reading
For some time now green has been the new thing and we live in one of its showcases, with access to all kinds of tropical nature within easy driving distance. But it has been where we live that, for the last few months, has had us greening our own living patterns. There will be a fuller post on that soon, but for now I just smile at my friends across the Atlantic, on a day when our rooster woke me as usual well before the sunrise. And opening the gallinero (chicken coop) on my way to the lower land we are planting, I was sensitive to the smell that I had otherwise stopped noticing until I read this short piece. I appreciate the imaginative approach, probably unique to France, to protecting heritage that some at best take for granted and others find a nuisance:
Townies v tractors
Some second-home owners have sued over loud livestock and church bells
France’s sense of itself has long been rooted in the land, even though three-quarters of French people live in towns. Now, however, having locked down in small airless spaces, many city-dwellers feel the call of the wild. Estate agents report an uptick in searches for homes with gardens. Diehard urbanites talk wistfully of a bucolic existence in la France profonde. In a poll, 61% of the French think confinement will encourage people to move to the country or buy a second home. But do today’s townsfolk know what rural life really entails?
The question arose late last year, when Pierre Morel-À-L’Huissier, a deputy from the Lozère, a remote rural area, introduced a bill to protect France’s “sensory heritage”. By this, he meant “the crowing of the cockerel, the noise of cicadas, the odour of manure”, and other rural sounds and smells. Continue reading
You’ve seen the news: vegetable seeds are selling out. All that quarantine ennui has combined with anxiety about the gaps on supermarket shelves to create a whole new population of city farmers in backyards and windowsills across America. And everyone from the Los Angeles Times to Forbes to CBS has dubbed these brand new beds of beets and broccoli “COVID-19 Victory Gardens.” Continue reading
When we started this platform, from a base in south India, we were surrounded by charismatic mega-fauna. Even the squirrels were unusually beautiful and large. The purpose of the platform being to highlight stories of creative, entrepreneurial approaches to conservation as much as to raise awareness of environmental issues more broadly, there is a new form of mega charisma worth noting today. It may make a difference to the issues we have been pointing to since the first post nine years ago:
Exclusive: project will store renewable energy and reduce climate-heating emissions
Construction is beginning on the world’s largest liquid air battery, which will store renewable electricity and reduce carbon emissions from fossil-fuel power plants.
The project near Manchester, UK, will use spare green energy to compress air into a liquid and store it. When demand is higher, the liquid air is released back into a gas, powering a turbine that puts the green energy back into the grid.
A big expansion of wind and solar energy is vital to tackle the climate emergency but they are not always available. Storage is therefore key and the new project will be the largest in the world outside of pumped hydro schemes, which require a mountain reservoir to store water. Continue reading
Birders, in general, tend to be an enthusiastic bunch – and the constraints of the current circumstances actually added extra incentive to find creative problem solving solutions, in finding new birding locations or ways to be safely be in familiar ones.
The BirdsCaribbean Global Big Day video compilation provides proof positive. Enjoy!
Of all the ways to transition to vegetarianism, which I am on snail’s pace doing, I just realized that the one form of animal protein that I have completely eliminated without thinking about it is fish. I cannot remember planning on doing this, but at this moment I cannot remember the last time I ate fish. It may have been 2016. But I have been conscious of the sensation every time I am grocery shopping that I avoid the fish.
Sushi was my favorite treat of a meal years ago, and while living in India we were as much pescatarian as vegetarian. But that changed with a growing awareness of the challenges related to regulating the world’s seas. So I quit eating things from it. Jennifer E. Telesca, writing in Yale e360, does not make me feel any better about this–as a data point I am exactly of zero relevance compared to the total market size–but I am gratified to see a book on a topic that will help me better quantify the reasons why exiting the market for fish is a priority:
The international commission responsible for managing Atlantic bluefin — prized for high-quality sushi — is failing to protect this magnificent fish. The regulators’ focus on fishing industry profits points up the need to change the way we view, and value, the lives of wild creatures.
In 2010, after years of global headlines highlighting the runaway harvest of bluefin tuna in the Mediterranean Sea and eastern Atlantic Ocean, the international regulatory agency managing this endangered fish capitulated. It cut the total allowable annual catch to 12,900 metric tons, the lowest level recorded. For the world’s most valuable fish, coveted as the most succulent sushi on the planet, a return to plenty looked promising. Continue reading
At first glance, it looks like art. As most great nature photography, whether amateur or taken by professionals, often does. But this is tech-driven professional science. Thanks to the Great Barrier Reef Foundation for this primer:
So how do you count more than 64,000 turtles at once?
With drones – and now we have the science to prove it.
Our Raine Island Recovery Project researchers are investigating the best way to count all the turtles at the world’s largest green turtle nesting area. The highly respected PLOS ONE journal has just published their findings (see the paper). Continue reading
Friday, one of the hotels where we operate Authentica re-opened. With not much exaggeration I can say that for hotel staff, for Amie and me, and for the Costa Rican guests we interacted with, seeing tourism start up again after three months felt emotionally kind of like this, only with serious social distancing.
Yesterday, day 2 of this experiment in moving forward, before going to greet guests at the shops we began on the land. Above is the first of what we expect to be a larger set of honey bee colonies that will pollinate our coffee and fruit trees. Amie is in beekeeping tutorial mode and after a few weeks in place it seems to my untrained eye that the bees are happy with her progress. The land surrounding the hive, and other parts of the property, have been planted with beans common to the Costa Rica diet–mostly black and red–and some special varieties that we favor, such as white and butter varieties. Those we planted first, as you can see below, are already sprouting.
While we look forward to their eventual edible state, the primary purpose of these legumes is to fix nitrogen in the soil in advance of planting when our coffee seedlings are ready. Regeneration of the nutrients will allow the soil to host the coffee we are preparing for the microlot restoration project, planned long before current crises and to bear fruit some time after we have figured out how to move on with life. For now, seeing guests again, having beans sprout and bees buzzing is good enough.
