#conservation and ecology

[great-and-small]

When I was in vet school I went to this one lecture that I will never forget. Various clubs would have different guest lecturers come in to talk about relevant topics and since I was in the Wildlife Disease Association club I naturally attended all the wildlife and conservation discussions. Well on this particular occasion, the speakers started off telling us they had been working on a project involving the conservation of lemurs in Madagascar. Lemurs exist only in Madagascar, and they are in real trouble; they’re considered the most endangered group of mammals on Earth. This team of veterinarians was initially assembled to address threats to lemur health and work on conservation solutions to try and save as many lemur species from extinction as possible. As they explored the most present dangers to lemurs they found that although habitat loss was the primary problem for these vulnerable animals, predation by humans was a significant cause of losses as well. The vets realized it was crucial for the hunting of lemurs by native people to stop, but of course this is not so simple a problem.

The local Malagasy people are dealing with extreme poverty and food insecurity, with nearly half of children under five years old suffering from chronic malnutrition. The local people have always subsisted on hunting wildlife for food, and as Madagascar’s wildlife population declines, the people who rely on so-called bushmeat to survive are struggling more and more. People are literally starving.

Our conservation team thought about this a lot. They had initially intended to focus efforts on education but came to understand that this is not an issue arising from a lack of knowledge. For these people it is a question of survival. It doesn’t matter how many times a foreigner tells you not to eat an animal you’ve hunted your entire life, if your child is starving you are going to do everything in your power to keep your family alive.

So the vets changed course. Rather than focus efforts on simply teaching people about lemurs, they decided to try and use veterinary medicine to reduce the underlying issue of food insecurity. They supposed that if a reliable protein source could be introduced for the people who needed it, the dependence on meat from wildlife would greatly decrease. So they got to work establishing new flocks of chickens in the most at-risk communities, and also initiated an aggressive vaccination program for Newcastle disease (an infectious illness of poultry that is of particular concern in this area). They worked with over 600 households to ensure appropriate husbandry and vaccination for every flock, and soon found these communities were being transformed by the introduction of a steady protein source. Families with a healthy flock of chickens were far less likely to hunt wild animals like lemurs, and fewer kids went hungry. Thats what we call a win-win situation.

This chicken vaccine program became just one small part of an amazing conservation outreach initiative in Madagascar that puts local people at the center of everything they do. Helping these vulnerable communities of people helps similarly vulnerable wildlife, always. If we go into a country guns-blazing with that fire for conservation in our hearts and a plan to save native animals, we simply cannot ignore the humans who live around them. Doing so is counterintuitive to creating an effective plan because whether we recognize it or not, humans and animals are inextricably linked in many ways. A true conservation success story is one that doesn’t leave needy humans in its wake, and that is why I think this particular story has stuck with me for so long.

If you aren't following the news here in the Pacific Northwest, this is a very, very big deal. Our native salmon numbers have been plummeting over the past century and change. First it was due to overfishing by commercial canneries, then the dams went in and slowed the rivers down and blocked the salmons' migratory paths. More recently climate change is warming the water even more than the slower river flows have, and salmon can easily die of overheating in temperatures we would consider comfortable.

Removing the dams will allow the Klamath River and its tributaries to return to their natural states, making them more hospitable to salmon and other native wildlife (the reservoirs created by the dams were full of non-native fish stocked there over the years.) Not only will this help the salmon thrive, but it makes the entire ecosystem in the region more resilient. The nutrients that salmon bring back from their years in the ocean, stored within their flesh and bones, works its way through the surrounding forest and can be traced in plants several miles from the river.

This is also a victory for the Yurok, Karuk, and other indigenous people who have relied on the Klamath for many generations. The salmon aren't just a crucial source of food, but also deeply ingrained in indigenous cultures. It's a small step toward righting one of the many wrongs that indigenous people in the Americas have suffered for centuries.

"England is celebrating the first pair of beaver kits born in the country since they were reintroduced back into the country’s north last year.

Landscape managers in England are beside themselves with surprise over the changes brought about by a single year of beaver residency at the Wallington Estate in Northumberland—with dams, mudflats, and ponds just appearing out of nowhere across the landscape.

Released into a 25-acre habitat on the estate last year, the four beavers at Wallington are part of a series of beaver returns that took place across the UK starting in 2021 in Dorset. Last year, GNN reported that Hasel and Chompy were released into the 925-acre Ewhurst Estate in Hampshire in January 2023, and the beavers that have now reproduced established their home in Wallington in July.

“Beavers are changing the landscape all the time, you don’t really know what is coming next and that probably freaks some people out,” said Paul Hewitt, the countryside manager for the trust at Wallington. “They are basically river anarchists.”

“This time last year I don’t think I fully knew what beavers did. Now I understand a lot more and it is a massive lightbulb moment. It is such a magical animal in terms of what it does.”

It’s believed that the only animal which alters the natural environment to the same extent as humans is the beaver. Their constant felling of trees to construct dams causes creeks to build up into pools that spill out during rainfall across the land, cutting numerous other small channels into the soil that distribute water in multiple directions.

Hewitt says that in Wallington this has translated to a frantic return of glorious wildlife like kingfishers, herons, and bats.

Recently the mature pair of beavers mated and produced a kit, though its sex is not yet known because beavers don’t have external genitalia.

These beaver reintroductions have led to a raft of beaver sightings around the country. Those at the National Trust working to rewild the beaver back into Great Britain hope the recovery of the landscape will convince authorities to permit further reintroductions to bigger areas."

“I loathe that word ‘pristine.’ There have been no pristine systems on this planet for thousands of years,” says Kawika Winter, an Indigenous biocultural ecologist at the University of Hawaiʻi at Mānoa. “Humans and nature can co-exist, and both can thrive.” For example, in the Proceedings of the National Academy of Sciences (PNAS) in April, a team of researchers from over a dozen institutions reported that humans have been reshaping at least three-quarters of the planet’s land for as long as 12,000 years. In fact, they found, many landscapes with high biodiversity considered to be “wild” today are more strongly linked to past human land use than to contemporary practices that emphasize leaving land untouched. This insight contradicts the idea that humans can only have a neutral or negative effect on the landscape. Anthropologists and other scholars have critiqued the idea of pristine wilderness for over half a century. Today new findings are driving a second wave of research into how humans have shaped the planet, propelled by increasingly powerful scientific techniques, as well as the compounding crises of climate change and biodiversity loss. The conclusions have added to ongoing debates in the conservation world—though not without controversy. In particular, many discussions hinge on whether Indigenous and preindustrial approaches to the natural world could contribute to a more sustainable future, if applied more widely.

(May 12, 2023) We are raising money for a crowd funded research project investigating the cause of blueberry hermit crabs in Okinawa, Japan using trash found on the beach as “homes” instead of natural shells. These hermit crabs are endemic to the southern islands of Japan, and they act as coastal environmental engineers. They are endangered on several islands, and we want to try and understand why they are resorting to beach trash for shells. Please consider sharing this post and donating to the project. The fundraising will be active for the next 45 days (until June 26). 

You can find all project details here: https://experiment.com/projects/blueberry-hermit-crabs-with-beach-trash-homes

We suspect that areas with high rates of tourism lead to beach combers collecting natural shells leaving nothing for the hermit crabs to use. It’s possible that overfishing of turbo snails which would naturally provide shells for the crabs may also be a factor. We will survey many sites across several islands in Okinawa to try and determine a cause of this behavior. 

We will be working closely with national geographic photographer Shawn Miller (photo credits above) and several researchers in Japan. Additionally, we will complete extensive beach clean ups in the areas we study. Thank you so much for reading!

If you learn and put into practice a SINGLE thing from my blog, it should be this: the most important work YOU can do to prevent mass extinction is not "Buy Different Product" or "Buy Product Differently."

Instead, it involves going outside and looking at the land immediately surrounding you physically and understanding that you have been appointed its protector, and then learning working contacting messaging organizing planting teaching informing organizing organizing organizing to take care of it.

There are old ladies with no email address in your community that are handing out more native plants than you knew existed, there are nature preserves and wildlife parks literally like on their knees begging for volunteers, you have neighbors and friends and acquaintances and family that you can teach and inform, there is at this very moment someone else in your community that would LOVE to start a community garden.

Learn to grow native plants and you can literally just hand them out to strangers for free and everyone loves it

I started volunteering at a nature center and now I have more contacts than I know what to do with. literally just look up anyone working in ecology or conservation in your area and email the crap outta them.

you can organize with members of your community to protect a vacant lot or a random pond or to put in foot paths or get rid of invasive species in a park or anything

A study that just came out demonstrates that outdoor cats are known to prey on over two thousands species of wild animal, from mammals to birds to insects. That includes 347 species that are endangered, threatened or otherwise of concern, and they've been a key factor of the permanent extinction of over 60 species. And while cats may not always bring home what they catch, chances are if your cat is allowed to roam unsupervised outside, they're killing your local wildlife.

Why is this so important? Worldwide, wild animal populations have decreased in number by 69% in the past fifty years; that means that in my lifetime (born in 1978), the sheer number of wild animals in the world has been decreased by over half. Even "common" wild species are less numerous than before. While habitat population is the single biggest cause of species endangerment and extinction overall, outdoor and indoor/outdoor cats are a significant cause as well. In fact, they are the single biggest cause of human-caused mortality in wild birds.

Most importantly, it's very, very simple to fix this problem: keep your cats indoors, and spay and neuter them. If your cat is bored, they need more enrichment, and there are plenty of ways to make your home more exciting for them, from bringing home cardboard boxes for them to explore, to playing with them more often. If you want your cat to get some outdoor enrichment, leash train them (yes, it can be done!) If you have the space and resources, build them a catio where they can be safe from outdoor dangers like predators and cars, while also keeping local wildlife safe from them.

If you just give into their whining and pawing at the door, then they know that that's what they have to do to get their way; I know it's a tough transition, but it's worth it in the end for everyone involved. Cats are domesticated, which means they are not native anywhere in the world; there are exactly zero ecosystems in which they belong, save for the safety of your home. It is your responsibility to give them an enriching environment without taking the shortcut of letting them go wreak havoc outside.

Do you live in Illinois? Please read <3

The Kirtland's Snake (Clonophis kirtlandii) is a Midwestern snake that lives in wetlands and grasslands. It is threatened, endangered, or extirpated (locally extinct) throughout its range. The species was rejected from "endangered species" status but will be reconsidered in the next two years.

Photo credit x

The Kirtland's Snake has been found in a preserve in Will County, Illinois (just south of Chicago), but a permit filed by the County indicates they plan to pave a trail straight through its critical wetland habitat.

Figure 2 from here showing untouched habitat they will be paving through. This is from the Incidental Take permit.

The "Incidental Take" refers to the individuals that will die as a result of this plan. The "Incidental take" in this case is estimated to be 3 snakes because they found 3 in the planned construction zone, but this does not consider 1. the small gene pool/population size 2. the loss of prey from damage to the wetlands (from wetland pollution and soil compression) and 3. overall habitat decreasing and 4. direct injury from human persons ie being run over by bikes or stepped on.

If you are a nature lover please consider emailing DNR.ITACoordinator@Illinois.gov , the Department of Natural Resources Incidental Take Authorization coordinator, and ask them to reconsider and strengthen protections for threatened species like this!

"The coral reefs of south Sulawesi are some of the most diverse, colorful and vibrant in the world. At least, they used to be, until they were decimated by dynamite fishing in the 1990s.

As part of a team of coral reef ecologists based in Indonesia and the UK, we study the reefs around Pulau Bontosua, a small Indonesian island in south Sulawesi...

In many places around the world, damage like this might be described as irreparable. But at Pulau Bontosua, the story is different. Here, efforts by the Mars coral restoration program have brought back the coral and important ecosystem functions, as outlined by our new study, published in Current Biology. We found that within just four years, restored reefs grow at the same rate as nearby healthy reefs.

Speedy recovery

The transplanted corals grow remarkably quickly. Within a year, fragments have developed into proper colonies. After two years, they interlock branches with their neighbors. After just four years, they completely overgrow the reef star structures and restoration sites are barely distinguishable from nearby healthy reefs.

The combined growth of many corals generates a complex limestone (calcium carbonate) framework. This provides a habitat for marine life and protects nearby shorelines from storm damage by absorbing up to 97% of coastal wave energy.

We measured the overall growth of the reef framework by calculating its carbonate budget. That's the balance between limestone production (by calcifying corals and coralline algae) and erosion (by grazing sea urchins and fishes, for example). A healthy reef produces up to 20kg of reef structure per square meter per year, while a degraded reef is shrinking rather than growing as erosion exceeds limestone production. Therefore, overall reef growth gives an indication of reef health.

At Pulau Bontosua, our survey data shows that in the years following restoration, coral cover, coral colony sizes, and carbonate production rates tripled. Within four years, restored reefs were growing at the same speed as healthy reefs, and thereby provided the same important ecosystem functions...

Outcomes of any reef restoration project will depend on environmental conditions, natural coral larvae supply, restoration techniques and the effort invested in maintaining the project. This Indonesian project shows that when conditions are right and efforts are well placed, success is possible. Hopefully, this inspires further global efforts to restore functioning coral reefs and to recreate a climate in which they can thrive."
