The Changing Conversation Around Invasive Species

Recently, the debate about invasive species has become more polarized than ever, with a degree of defensiveness and anger not seen previously. The reasons for this are many, some difficult to admit to.

Chinese Clematis may be invasive, but it deserves a less bigoted name.

I attended a webinar a few weeks ago in which the presenter asserted that “invasive species” is a “militarized term.” My instinctive reaction was that this was accusatory, bordering on defamation of science, when there is clear evidence that the introduction of a species to a new ecosystem can have devastating consequences.

Spongy Moth is still a bonafide forest pest, but now has a more appropriate moniker.

Pondering his comment further, it occurred to me that most of the animals, and plants, we label as invasive have some sort of obvious and negative economic impact. We have, as a consumer culture, become conditioned to frame everything in terms of business and monetary interests rather than ecological concerns. This has become more complicated by angst over climate change, and the resulting vulnerability of humanity to emerging threats, be they viruses or “murder hornets.”

The sudden, and/or overwhelming appearance of a novel organism is going to cause alarm, and the public seldom has comprehensive, appropriate knowledge for interpretation of potential impacts. We are at the mercy of what news outlets tell us. Because traditional print, radio, and television media now compete with social media, sensationalism is the order of the day. “Click bait” banners prevail over more accurate but less provocative headlines.

Initial forecasts can also be premature. The jury is still out on whether some recently-introduced species will become problematic. They may not. The Joro Spider is a case in point. It is locally abundant in some parts of the southeast U.S., but whether this translates to a displacement of native spiders remains an unanswered question.

We collectively have a fascination with heroes and villains, too, and there are no more menacing villains than alien-looking insects, spiders, and other arthropods. Fantasy melds with reality and it becomes difficult to separate the two if you are not scientifically literate, or have a business model that demands public hatred of a particular creature.

In opposition to nativism is the idea that there is no such thing as invasive species. After all, man is part of nature, and therefore our actions are natural processes. The outcomes of those activities are circumstances to which we, and other species, will adapt.

It may be no coincidence that a backlash against the idea of invasive species is more evident now that we are recognizing, and attempting to mitigate, a history of colonialism. A convincing argument could be made that White settlers are the original invasive species. Here, in North America, we annihilated and displaced Indigenous members of our own species. We enslaved others. To this day we continue missionary work and other forms of colonialism. Therefore, the idea of invasive species becomes one of self-loathing, certainly an eventual threat to White supremacy and privilege. White people do not want to see themselves as villains.

Meanwhile, we demonize human immigrants and refugees as criminals and threats to domestic labor pools. We clamor for the closure of borders to our fellow humans, but allow our boundaries to be permeated by everything else. Not that human-imposed boundaries reflect natural ones.

The Cross Orbweaver, Araneus diadematus, is an example of a naturalized arachnid in North America.

Scientists have an uphill battle in resolving these opposing perspectives and initiating constructive dialogue. Looking to the past we see how some species from foreign lands have become “naturalized” over time, becoming innocuous additions to our flora and fauna. The average citizen may be shocked to learn that dandelions are not native to the U.S. They have become a fixture in our lawnscapes, even if we are instructed to use weed-killers against them.

Myrtle Spurge, aka "Donkeytail," Euphorbia myrsinites, is classified as a noxious weed in some jurisdictions, but not everywhere.

What is lost in all of this is attribution of the modern problem of invasive species to global consumer culture. Historically, human colonists brought other species with them as a guarantee of food and other necessary resources when venturing into unknown territory. Soon after, those species and their products became valuable in trade, a way to establish meaningful and positive relationships with Indigenous peoples, or other settlers. The pace of travel was slow, and the scale of enterprise miniscule compared to twenty-first century business.

Today, we mostly covet plants and animals of far-off lands. Plants, especially, can harbor potential insect pests. The containers used to transport international commerce are frequently occupied by insects, rodents, and other organisms. We seldom make that connection between our consumer habits and the state of ecosystems around the world.

Captive Reticulated Python. Release of unwanted Burmese Pythons into the Everglades by irresponsible pet owners has been....problematic.

We cannot turn the clock back, but we should make more informed and conscientious individual choices in the marketplace. We should promote the welfare of Indigenous peoples, and actively seek their counsel and leadership in crafting a world better able to withstand climate change. A permanent end to colonialism would not be a bad thing, either.

Why I am Reviewing The Trayvon Generation in a “Bug Blog”

I have been accused of being “political” even in some of the entomology posts in this blog, but there is nothing political about human rights. It is my opinion that there will be no abatement of the “insect apocalypse,” no permanent success in the conservation of endangered species of any kind, until we save our own species from racism and other forms of bigotry afflicting people of color, women, agender persons, the LGBTQ population, the disabled, the neurodivergent…..

The list of persecuted Homo sapiens continues to grow thanks to colonialism, patriarchy, white supremacy, religious extremism, extreme capitalism, ableism, and the inertia of assumptions. Because of this, what is inappropriate is to exclude discussions on these urgent matters from any forum, no matter how “off topic” it might appear at first glance. It is relevant to every facet of our lives, every profession, and every pursuit.

Elizabeth Alexander is a critically-acclaimed author, poet, educator, and scholar. Her book, The Trayvon Generation (Grand Central Publishing, 2022), is a must read. It is short, at only 130 pages, so there is no excuse for even the slowest reader like me to not get through it in a timely manner. It is not a rehashing of the Black history that whites already think they know. It is deeply personal, and highly illuminating.

Alexander draws on the works of other Black scholars, writers, and artists to literally and figuratively illustrate her points throughout the three-part text. The images of these creators, and the images created by Alexander’s eloquent prose, are moving, haunting, and indelible.

One chapter is entitled “whether the negro sheds tears.” The question, asked of the Black scholar W.E.B. Du Bois in 1905 by a (presumably white) researcher, parallels another query I addressed here previously: “Do Insects Feel Pain?” The implication of the question is similar to what Alexander concludes about questions of Black emotional expression:

”Are Black people human? Do Black people do what people do. Are Black people people. If Black people are not people and do not cry, then they do not experience pain, or grief, or trauma, or shock, or sorrow. If Black people do not experience pain, or grief, or trauma, or shock , or sorrow, are they human? And if they are not human, can their continued violation be justified?”

The artifice of race cannot stand, but Alexander allows for you to come to that conclusion. She demonstrates how even she herself once experienced the “shock of delayed comprehension” at the normality of white supremacy and expectation of Black servitude in the form of a painting of Elihu Yale with this Servant, hung prominently in the Corporation Room at that Ivy League university where she worked. She had failed to previously notice the servant in the painting, or mentally censored the offensive nature of the portrait.

Many such examples abound in our daily lives but we have been conditioned to accept them as normal, as acceptable. Recognition of artworks depicting white supremacy, hostile government and business policies, mass incarceration, wage gaps, and other obscene transgressions against people of color is what is met with anger and outrage by people who stand to lose power.

I care not one whit if I lose “followers” as a result of urging you to pick up The Trayvon Generation and begin a journey toward true humanity that embraces all beings, and takes action to make it so. Imagine the heights to which our species could climb were we to extend white privilege to all ends of the human spectrum.

J. Drew Lanham is Why I Will Still Write This Blog

On February 4 I was prepared to sacrifice this blog in protest of the desecration about to take place at the National Butterfly Center, Bentsen-Rio Grande Valley State Park, and all the refuges, sanctuaries, places of worship, private properties, sacred lands, historical lands, and current livelihoods in the Lower Rio Grande Valley.

I was about to engage in an indefinite "blog-out" as my own hunger strike against the current U.S. presidential administration, the newly-elected (if democracy even applies) leaders of Brazil and Madagascar, and the announcement of a new highway that will likely spell the end of rainforests on the island of New Guinea.

When I feel like I am being punished, pummeled....bullied, as I do now watching everything I hold dear being dismantled and destroyed by our current government and those who support it, my impulse is to hit back. My desire is to make tangible the psychological anguish I feel. It is the same behavior seen in toddlers and entirely too many men who throw things, break things, inflict violence on the innocent. They want you to feel physically the emotional pain they suffer from, but their methods of doing so simply compound our collective societal problems.

So, my warped reasoning was that if I cannot have nice things like wildlife refuges, the right to the opportunity to experience wild places abroad, etc, then I will deprive you of my knowledge of entomology, my skills as a writer, and my thought-provoking ideas and opinions. You do not deserve them if you are silent about things that matter more than money.

Then I read the following post on Facebook, by a writer, conservationist, historian, and activist who I have come to consider a mentor. Dr. J. Drew Lanham (pictured above) is an Alumni Distinguished Professor of Wildlife Ecology at Clemson University, and an award-winning author. He penned this on Facebook before turning in for the night:

Insomniac's Lament

For far too many in these times, the hours fall by as joyless days. We worry and fret over everything. EVERY. THING. Each word is a transgression every thought a crime waiting to be committed. I try hardest to be my best but I know at some point soon I will fail. Isn't it inevitable? What if in my earnest attempts to be human, my imperfectionz somehow mar the perfect person I never was? Who will report my wrongs and send me to ruin? Will I show up here or on the six o'clock news? We are overwrought and wrung out with angst waiting for the worst to happen because we'll be better off in some other end. It all has my head hurting and my heart sore. Is there some cure?

Hate has found its way into my soul for people I don't even know beyond what they "tweet, or what the headlines tell me to believe -- and I cannot find the switch to flip and make it stop. Perhaps if I could only learn to somehow ignore-- but then I cannot deny or turn a blind eye to so much going wrong. There are far too many "ist's" and "isms" still with us. Fighting them all at once is like an eternal career in uphill stone rolling. Just call me Sisyphus. The stress keeps me up late into the night and makes me want to sleep midday even more. Withdrawing seems the easy answer -- just closest family and a few treasured friends --sometimes; and always wildness and birds. Wildness. and Birds.

I guess tomorrow (which has just become. now) is another day.

I'll be okay. If I just read the right books and watch the right things. Somewhere some thought police will allow me clearance. Won't they?

Anyway, sleep mercifully calls. I'll wake soon from a brief nap to wren chatter and roll the rock upslope again. I'll just think of it as job security. Sanity slips in the witching hour but for a few moments soon after the sun comes up, I'll steal away --out there, where joy comes in the form of feathers -- and I can be a movement of one before the hamster wheel spins again-- for just a few moments I'll be hashtagged to a singular cause. Just Being.

Thank you, Drew, for expressing exactly how I feel, and compelling me to soldier on, resisting not just injustice and greed and arrogance and ignorance, but my own compulsions to pull the plug on what I do best.
