Other less well known species make their homes at Safari West, and many of these are on the list as well. Did you know for instance, that every lemur species on the planet has made the list? The famous ring-tailed lemurs (Lemur catta) qualify as “Endangered”. While both our black and white ruffed lemur (Varecia variegata) and red ruffed lemurs (Varecia rubra) sit in the “Critically Endangered” category. You’d never know it as you watch them frolic at the preserve, but these lemurs’ wild cousins are in crisis.

Bird Numbers in Decline

Alongside our big mammals, Safari West houses a large number of endangered birds as well. The hooded vulture (Necrosyrtes monachus), like so many vulture species, teeters on the edge of extinction. “Critically Endangered”, hooded vultures have suffered from a variety of modern issues, ranging from expanding agriculture and its overuse of pesticides to inadvertent poisoning. The incredibly strong stomach acids of vultures can actually digest the lead ammunition left in the carcasses of many human-hunted animals. This very thing accounts in part for the decline of the magnificent California condor as well.

The Waldrapp ibis (Geronticus eremita)—which also looks a bit like a vulture though it isn’t—was until very recently classified as “Critically Endangered” as well. Ominous looking birds, they once ranged across much of Europe, North Africa, and the Middle East. Over time, their numbers dwindled until only few widely scattered colonies remained. Enormous effort and energy has been expended trying to conserve this species and it appears to have paid off. Migratory by nature, Waldrapp ibises have begun to revisit some of their ancestral ground, showing up in places like Saudi Arabia, Yemen, and Turkey.

While Waldrapp numbers are still vanishingly small (only 200-250 mature individuals) the population has mostly stabilized, leading to reclassification in the fall of 2018 from “Critically Endangered” back up to “Endangered”. A small victory to be sure but in the fight for wildlife conservation, we treasure victories of any sort.

Struggles in the Sahara

Alongside the Waldrapp ibis many North African species face an uncertain future. Many of our most endangered mammals hail from the same arid region. The Sahara desert is among the most inhospitable regions on the planet. Species that thrive there are by their very nature, desert specialists. Specialists tend to have a tough time adapting to rapid change. Things like urban sprawl, oil exploration, expanding roadways, and war have all had a major impact on these desert species.

The beautiful scimitar-horned oryx (Oryx dammah) falls under the direst of classifications: “Extinct in the Wild*”. Wild scimitars have not been seen since the late 1980’s and the species survives solely in human-managed care. It’s worth pointing out that classification nearly always lags behind the reality on the ground. Counting animals in the wild is hard and proving extinction even harder. Although the last wild scimitar disappeared around 1989, the “Critically Endangered” classification persisted for a decade before they were finally recognized as “Extinct in the Wild*”.

The addax (Addax nasomaculatus), a spiral-horned antelope from the same Saharan region falls under the “Critically Endangered” classification. While the official estimate puts their population at around 100 individuals, some suspect that like the scimitar, the addax may already have gone extinct in the wild as well.

Reason to Hope

Extinct means extinct and extinct is forever. But “Extinct in the Wild” means we still have a chance. Thanks to places like Safari West, conservation facilities that care for and propagate human-managed populations, sometimes we can come back. In the decades since the scimitar-horned oryx disappeared from North Africa, herds of these animals have thrived in zoos, wildlife parks, and conservation breeding facilities across the globe. Just within the last few years, a massive cooperative program has begun to slowly reintroduce these animals to their ancestral home. This reintroduction program gives us reason to hope. While we may have lost the dodo, the stellar sea cow, and the passenger pigeon, perhaps we don’t have to lose these species.

We should be encouraged by the scimitar reintroduction program, by the upgraded classification of the Waldrapp. We should continue to work to find ways to live less impactful lives. To pursue balance with our environment. To give as much as we take. On Endangered Species Day, we want to take a moment to look honestly at the situation faced by so many species and ecosystems. But we don’t want to let it discourage us. There are still ways to conserve what’s left. Still ways to build a better tomorrow.

Thank you for supporting Safari West and all the other facilities and programs like us. And thank you for joining us and commemorating this Endangered Species Day.

*as of 2023, the status of the scimitar-horned oryx is now Endangered, which is a huge victory for the conservation and survival of this species!

Taxonomy, in its purest form, is simply a system of naming. It’s a scientific card catalog that says what everything is from the blue whale to the bumblebee. It begins with the broadest of categories—whether a thing is a plant, an animal, or something else—and narrows it down from there.

The trouble with taxonomy is that it’s a very complex concept dressed as a very simple idea. The simple idea is as follows: humans like to name things. We’re very good at it, so good in fact that we do it without even realizing. We do it to make sense of our world and organize our experiences. In doing so, we typically create hierarchies of complexity.

According to my high school biology textbook, we use 7 categories to describe a living thing. They start with the very general and proceed down to the very specific: Kingdom, Phylum, Class, Order, Family, Genus, and Species. Those final two, the genus and species, make what we call a binomial, or the scientific name for an organism.

You’re probably familiar with a few of these even if you don’t know it. The most famous is the binomial we use to describe ourselves, Homo sapiens. We can often get away with referring solely to the binomial because so many of the higher categories are broad enough to be assumed. Thus instead of saying that human beings are-

Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Primates
Family: Hominidae
Genus: Homo
Species: sapiens

We get away with simply, Homo sapiens (this is similar to how you can say “the point guard for the Warriors” rather than, “the point guard for the Golden State Warriors, Western Conference Pacific Division, National Basketball Association”).

Taxonomy in Evolution. Evolution in Taxonomy

The problem of taxonomy comes about because nature doesn’t work in categories but in continuums. Over the centuries, we have developed numerous methods to categorize species; each with their individual strengths and weaknesses.

In earlier times, humans would rely on what we could see to classify one species from another. If a group of plants looked like one another and distinct from all the rest, they would be described, named, and categorized as a distinct species.

This would later evolve into the most well-known of our many classifying schemes; the biological species concept. This concept operates on the idea that it’s not necessary for the members of a species to look the same, so long as they can interbreed successfully. If you take a rattlesnake and place it in a habitat with a cobra, they will not breed, and what’s more, even if they did, they couldn’t produce little rattle-cobras as a result.

This system, popular and functional though it is, has its share of problems. Not all species that don’t interbreed, can’t. Lions and tigers, for instance, don’t interbreed under natural conditions, yet they can produce a viable hybrid. Does this make them the same species? Most biologists would argue no. And what about asexually producing life? It doesn’t breed at all, so how do we go about defining it?

Enter DNA

In recent years, advances in genomic sequencing have added further complications to the field. It’s become more and more common to come across headlines about genetics demonstrating that what we thought was a singular species is actually two or more in disguise. How are we doing this? What does the genetics actually tell us?

Simply put, genetics tell us whether or not different populations are interbreeding. Consider the giraffe. Giraffes have long been considered a monolithic species. They can be found scattered across Africa and whether in Namibia or Niger, Zimbabwe or Zambia, the animals are relatively indistinguishable. We can isolate some general differences in coat color and patterning but overall, they appear highly similar and are more than capable of interbreeding.

But do they?

Giraffe Fracas

Recent research into giraffe genetics indicates that the total population is not only geographically fragmented but reproductively so as well. According to research conducted in partnership with the Giraffe Conservation Foundation, there appear to be four distinct groups of giraffe that haven’t interbred for a good long while. This has led to a push to have the giraffe reclassified from one species to four.

But debate continues. The populations may not be interbreeding, and apparently not for generations, but does that really make them separate species? If they weren’t living so far from one another, would they interbreed? Are they breeding at all where populations overlap? These are but a few of the questions demanding answers.

A Conspiracy of Lemurs

The possible re-categorization of giraffe sounds revolutionary, but in truth, this kind of thing happens all the time. Safari West recently became home to three red ruffed lemurs (Varecia rubra) and has long been home to black-and-white ruffed lemurs (Varecia variegata). These two species are closely related, occupy similar and geographically overlapping habitats, and differ only in physical appearance and vocalization.

Until very recently, both black-and-white ruffed and red ruffed lemurs were considered to be the same species. A recent study determined that the two lemur types don’t regularly hybridize. Further, it appears that a large river in Northeastern Madagascar completely separates reds from black-and-whites restricting them from possible interbreeding. Thus, they have been reclassified as distinct species (and the only living examples of the genus Varecia).

Let’s Get Political

What on Earth does this nuanced and complex branch of science have to do with conservation?

Two primary forces granting legal protection to many vulnerable and endangered species are the Convention on International Trade in Endangered Species (CITES) and of course, the Endangered Species Act (ESA). Both the CITES treaty and the ESA have proven immensely valuable in conservation work not only here at home but across the globe. These twin policies have had broad reach and deep impact but their success has also led to a sometimes problematic focus on the species.

You see, if a species is in danger of extinction across its range it then becomes relatively easy to achieve protective measures. If however, it’s only endangered in some places, that becomes less true.

The recent downgrading of giraffes from a species of least concern to one vulnerable to extinction came about because of data showing a decrease in their population of over 40%. However, if the scientific community agrees that there are in fact four distinct species of giraffe, then the numbers change. The reticulated giraffe population, for example, has plummeted by over 80% making them far more endangered than the current classification implies.

A Newer (Better?) Way of Thinking

If this has inspired in you a deep curiosity about the convoluted happenings in the world of taxonomy, great. There’s a whole, wide world of life out there that we need to better understand and identification is a huge first step. If you’re just wondering what my point might be, here it is: our reliance on identifying endangered species when planning conservation strategies is problematic.

Not only are species little more than cogs in the overall clockwork of an ecosystem, but on occasion, they’re not even clearly-defined cogs. It may be less important how any one categorized species is doing on a global scale and more important to consider ecological stability on a local level.

If we had all the giraffe we ever needed in South Africa, but they were to disappear from all the other countries in their current range, that would be a problem. The ecosystems in Kenya, or Botswana, or Zambia, would suffer major changes with the loss of such a large and charismatic species. And like falling dominos, those shifting ecosystems would impact neighboring systems.

The lines between species are vague and malleable just like the lines between ecosystems and they’re all interconnected. The trouble with taxonomy is that it encourages categorical thinking. We can plan conservation tactics categorically, but conservation in action must be holistic.
