Are there just about enough elephants? What is the right number of rhinos? Is there such a thing as an appropriate population of polar bears?

As we continue to monitor coronavirus numbers amidst the current round of hotspot whack-a-mole, conservation scientists are paying close attention to another important set of planetary health figures—rising extinction rates among the estimated 2 million documented species that make up the natural world. From the littlest lemur to the biggest tusker elephant, regardless of size, the unique genetic make-up of every species contributes to the diversity of life. And it’s that biological diversity that keeps our ecosystems stable and functioning, which is a really good and necessary thing for the well-being of all of Earth’s inhabitants.

Protecting and preserving the interdependent members of interconnected ecosystems is a massive, multi-faceted challenge. Is there a single target number that we should aim for that can be applied across millions of species to ensure that we can all keep on keeping on? Like the web of life, it’s complicated. Every species loss reduces diversity and weakens the web to varying degrees.

Scientists calculating how many species we can afford to lose have come up with a clear numerical goal to raise public awareness so that biodiversity conservation can be front and center as we make plans to protect nature better post-pandemic. According to their June 2020 report, the current rate of extinction is estimated to be up to 2,000 species a year—much higher than it should be so that Earth can continue to function as we like it. To help reduce extinctions everywhere on the globe, and to ensure that there is a place for everything and everything is in its place for proper planetary functioning scientists are recommending that we don’t exceed 20 extinctions a year across all species and ecosystems. From 2,000 to just 20.

Can we do it? To quote the stoic’s stoic, Marcus Aurelius, “…if a thing is humanly possible, consider it to be within your reach.” Through international cooperation, conservationists believe it is within our reach to reduce the number of species extinctions globally. As a case in point, despite a very turbulent year that has all but eliminated the tourism that provides critical support to conservation groups in biodiversity hotspots, Big Life Foundation continues to crush the megafauna extinction curve in Kenya. One of the most effective conservation organizations in Africa, Big Life protects and secures wildlife in 1.6 million acres of some of the most important natural habitat left in the world. And through the development of programs that benefit local communities, including critical health and education initiatives, Big Life also supports the people who will support conservation into the future. Winning hearts and minds through clever community-based conservation for healthy people on a healthy planet—most definitely humanly possible.

You can find out what’s currently happening on the ground in Kenya from Big Life’s conservation scientist Jeremy Goss and head of security Craig Millar here. If you would like to explore the strikingly evocative wildlife photography of Big Life co-founder Nick Brandt you can do that here. And if you’ve got any headspace left to monitor non-COVID-19 numbers, you can keep tabs on 95% of species known to science at the Catalogue of Life.

Before we go, we’d like to bid farewell to the smooth handfish. The last of its fish-fingered kind has officially departed the planet—the first modern-day marine fish to be declared extinct. We just got to know you, but we miss you already.

Dolphin See, Dolphin Do

2-minute read

While imitation may be the sincerest form of flattery amongst humans, for dolphins, believed to be the second most intelligent creatures on Earth, copying the behavior of finned friends is very much a practical matter—it’s all about upgrading fish acquisition skills.

According to new research from scientists working with the Dolphin Innovation Project at Australia’s Shark Bay Marine Reserve, the clever cetaceans are making the most of their ability to absorb and apply knowledge by forming alliances outside of their families and learning specialized tool-using techniques to increase the day’s catch.

Like many young in the animal kingdom, bottlenose dolphin calves typically pick up foraging know-how from their mothers. However, the Shark Bay study revealed that the cognitively advanced animals recognize a good idea when they see one—even if it doesn’t come from mom. The dolphins are also motivated to learn tool-based foraging innovations from social interactions with non-parental adults. This marine life mentoring has resulted in the spread of an ingenious prey capture strategy known as shelling.

By observing and imitating others, a small group of dolphins in Shark Bay have learned how to trap prey in large gastropod shells, lift the shells above water, and shake them to dislodge and devour the fishy contents. This is how they do it.

Researchers believe the dolphins may have developed the trap and shake method of foraging to adapt to environmental change. For two years following a 2011 heatwave that caused a reduction in food supply impacting their reproduction and survival, the dolphins’ shelling behavior increased by 50%. By taking advantage of opportunities to interact and learn from other adults, the Shark Bay dolphins increased their resilience to life-threatening ecosystem stressors. Who’s a super-smart, social-networking aquatic mammal!

By the way, the Shark Bay Marine Reserve is located in Useless Loop. Is there a better town name? Well, there might be, but we haven’t come across it!

If you’d like to help ensure bottlenose dolphins can keep on being their big-brained, tool-using selves, you can contribute to the mission-critical conservation of marine habitats by participating in Plastic Free July, a global movement to give up the indestructible stuff and return our oceans to their prior state of pristine. Feeling motivated to reduce your use of plastic at home, school, and work? You can get all sorts of inspiring ideas about how to cut it out from the good people at the Plastic Free Foundation.

As a powerful visual reminder of how much plastic ends up in our oceans (8 million metric tons a year!), the talented artists at Oregon’s Washed Ashore Project have created a menagerie of 80 beautiful and thought-provoking wildlife sculptures constructed from debris collected from local beaches. If you’ve ever wondered what a shark, seal, or sea turtle built from bottles, buckets, and gumboots might look like, wonder no more. You can take a peek at Washed Ashore’s current art to save the sea exhibits here.

Calling All Tree Lovers

1.5-minute read

We thought we’d start off this unusually unusual July with a celebration of something cool and comforting and lovely and leafy—trees—ahhh! We write about trees and plant trees and tend to trees because well, we’re tree people and because they’re the unsung green heroes of the planet. We believe in giving nature credit where credit is due, and so do our planting partners at American Forests, which is why since 1940, they’ve sponsored a national hunt to locate and crown the most colossal of America’s trees.

So if you’re looking for a perfect activity to help you keep your social distance during the dog days of summer, it’s officially tree-tracking season, time to hit the lonesome trails, and keep your eyes peeled for a massive marvel in your local field, forest or national park. Your mission, should you choose to accept it, and we hope that you will, is to locate, measure and nominate the largest tree you can find to American Forests’ National Register of Champion Trees. Learn how to propose a potential champion, then gather your tree’s photos, facts and figures and submit your awe-inspiring specimen for consideration beginning October 1, 2020. Not only will you be contributing to forest heritage, you’ll also be helping scientists learn more about how large, old-growth trees capture and store carbon and filter water.

If wandering in one of 419 U.S. national parks in pursuit of gargantuan trees is on your safely-able-to-do list, you can also share your unique photographic point of view in the federal recreation lands photo contest. Check out rules, recent snaps, and previous winners here.

And if you’d like to find out which trees were the 2020 favorites of our nature-loving friends in Europe, you can read the winning stories of the Guardian of the Flooded Village, the Gingko from Daruvar, and the Lonely Poplar at the aptly named European Tree of the Year.

To borrow from EU environmental expert Ladislav Miko, we celebrate trees and get to know their stories to learn why they are important for us as humans. Tree lovers and tree admirers create a good society of people.

We always knew being a citizen of nature would come in handy.
