I am excited by an artistic theme I have been pursuing these past months. I have named the series ‘Flora-Persona.’

Using only natural materials, including plants, trees and associated leaves and seeds, and avoiding the use of any manmade materials during the creative process (such as paints, adhesives, and dyes), I purposefully manipulate plants and other flora in a zoomorphic or anthropomorphic manner.

Relying solely on Nature’s bounty is an artistic departure for me in some ways, yet a continuum of my focus on addressing the rising environmental damage, including climate-related disruptions, which our industrialized world has wrought.

Inspired by my research in support of my painting entitled ‘Wood-Wide Web’ (which I previously presented on ClimateCultures in my post with Eva Strautmann), I became acutely aware of the ability of various tree and plant species, along with fungi, to communicate and share resources with one another in a symbiotic manner.

‘Wood-Wide Web’ portrays a forest, field, or meadow not merely as a collection of competing individuals in a shared location, but rather as an interconnected community where resource sharing and communication play a significant role in the health and resilience of the entire ecosystem.

Mitakuye Oyasin: we are all related

My research led me to read about the Mother Tree Project. This large-scale, decade-long research effort led by Dr. Suzanne Simard at the University of British Columbia, revealed that neighboring trees and plants are in communication with one another via an underground network of fungi that resembles the neural networks in our brains.

I was astonished to learn that in one study, Simard documented that a Douglas fir tree that was injured by insects appeared to send chemical warning signals to a Ponderosa pine tree growing nearby. The pine tree then produced enzymes to protect itself against the nearby insect invasion.

To me, a form of collective consciousness was in play within the web of life, across at least two Kingdoms. In biological taxonomy, life forms are organized into hierarchical groups: Kingdoms are at the top, with phylum, class, order, family, genus, and species being progressively lower tiers.  Fungi are in a separate Kingdom from trees and plants, yet they support one another in a mutually beneficial way.

Not so with respect to humanity, the alpha species in the Kingdom of Animalia. I began to see more clearly that we don’t support the interconnected web of life, and in fact we continue to disrupt the very symbiotic fabric that the wood-wide web illustrates.

During my daily walk in the woods behind my home, I began to consider more thoughtfully how alienated we all are from the natural world, and I began to ponder how a conscious wood-wide web of interconnected life that surrounds me might view humankind. Yes, not a comforting thought.

A note on captions: I really hadn’t thought of specific captions for images of these works, seeing them more like an anthropological or archaeological ‘find’, where present-day humans have to surmise the intention of long-ago peoples when assessing disjointed remains of their social and cultural mores and beliefs.

The artistic concept of ‘Flora Persona’ formed slowly. My evolving viewpoint was also informed by a Lakota phrase, “Mitakuye Oyasin” (“We are all related”). The phrase expresses the idea that every living entity shares the same divine origin and life force, and that humanity is part of a complex reciprocal web of existence, rather than separate from, or superior to, nature.

My artistic interest was thus stimulated by both non-Western and ancient beliefs concerning the shared web of life and by my newfound understanding that plants and trees have some form of elementary consciousness, as demonstrated by their ability to communicate across species, genus, families, and all the way up the hierarchical groups, to include across the two noted Kingdoms.

Reaching back to our roots in art

Both climate and human culture, including artistic expression, have intersected in many ways throughout our species’ course of time. In this evolving series, I delve deeply into our ancient past for artistic inspiration. I suggest that we have been creating art across the various climate epochs we have inhabited, since times immemorial. I believe that both the flora and fauna available in long-ago times provided source materials used to create art, back into earlier hominin eras.

It is reasonable to assume that humans have been making art from biodegradable materials, including masks, figurines, and sculptures, for more than one hundred thousand years.

Masks and sculptures have been my primary focus to date. My artistic goal is to present man-manipulated natural elements in a manner that harkens back to our early ancestors.

With respect to cave paintings, the earliest known artistic expressions for both Homo sapiens and Neanderthals, consisting of non-figurative symbolic markings, are more than 70,000 years old. They are still in existence today, due to their isolation and protection from the weathering elements. Other art, made from natural materials and not contained within caves, clearly has not been preserved.

One of my flora-persona series interests is using burdock (Arctium lappa) seed heads to create extinct local animals that were plentiful in my region of Maryland, USA during the Woodland and Archaic Periods — such as the wooly mammoth and the cave bear. It is my contention that such natural materials were used to create art by these ancient native ancestors, and indeed perhaps as far back as our early hominin ancestors.

Burdock plant and collected seed heads, as well as a few examples of my ‘Burr Art ‘, are presented below:

Plant masks: viewing how our relatives might see us

With respect to making human-like faces from plant leaves, I was inspired to begin this Flora-Persona series when pondering the wood-wide web and, particularly, the nascent consciousness documented via chemical communication networks formed between fungi, plants, and trees.

These leaf masks are not necessarily made to be worn. Rather, they are meant to present these wonders of nature as a member of our distant family, aligned with the Lakota phrase “Mitakuye Oyasin”: we are all related.

I continue to experiment with different plants, seeds, leaves, and tree bark, all picked up along my daily walks in my neighboring Black Hill Park. I find myself drawn to creating leaf masks that present the viewer with an unsettled view of how we humans might be viewed by our distant plant relatives, such as displaying sorrow, shock, disappointment, and anger. These sentiments seem very proper to me, considering the continuing harm we cause to the interconnected web of life.

Below are three photos. The first shows how I applied juice to several of my leaf masks, a natural dye from ripe purple pokeweed berries that I had gathered.

Michael — “I used Gemini AI as a background search tool — looking for other examples of both my ‘burr art’ and ‘leaf art.’ Frankly, not much out there — at least from my initial research.”

Michael adds: “A young friend from Scotland, after looking at my burr art, brought to my attention the annual ancient event called the ‘Burryman,’ which happened to occur mid-August. The Burryman is a centuries-old Scottish folk tradition where a local man is covered head-to-toe in thousands of sticky burdock burrs and paraded through the area.” Find more at Wikipedia.

This piece for the Ecological Disciple by Lenore Three Stars, The Way Forward: Mitakuye Oyasi — A Worldview (11/6/26) explores the value of an approach to our shared world that starts from the position that “We are all related” (Mitakuye Oyasi can also mean “All my relations.”)

Protest Posters for the Earth!

Artist Michael Gresalfi explores the history of protest posters and their use for International Mother Earth Day (22nd April) through his own protest painting, “Replenish The Earth”. Michael invites fellow ClimateCultures members to share their Earth Month creations.

While Earth Month (and Earth Day) originated in the United States, it has become a massive global phenomenon. Today, it is recognized in over 193 countries, with approximately one billion people participating in environmental actions each April. In 2009, the UN officially designated April 22nd as ‘International Mother Earth Day.’ This solidified the April date as the primary global standard.

Earth Month needs artists like you

Artists of all mediums have engaged in this annual event through many different ways, including designing and then displaying ‘protest posters.’ From the broadsheets of the Reformation to the neon-soaked digital projections of today, protest posters have been used as a visual megaphone, and to get the message out in public forums to the people.

Legend says Martin Luther kicked things off by nailing his Ninety-Five Theses to a church door. Whether he used nails or glue, he effectively used the first ‘protest poster’ to challenge the most powerful institution in Europe, the Catholic Church and its Pope.

The Suffragettes were the first to master protest branding. They realized that for a movement to be taken seriously, it needed a cohesive look. They used purple (dignity), white (purity), and green (hope) on banners and sashes.

A golden age of protest posters

Perhaps the 1960s and 1970s might be considered the golden age of protest posters. Both the civil rights movement, and the anti-Vietnam war movement maximized the use of bold, artistic, and visceral protest posters and other forms of imagery for mass media consumption.

Here is a sample of those vintage environmental protest posters:

The advent of the so called ‘digital revolution’ had a major impact on the universal growth of protest posters. This phenomenon was kick-started by the accessibility of personal computers, affordable color printers, and the Internet.

“Replenish The Earth” – a call to creative action

So, my fellow ClimateCultures members, what are you creating to share during Earth Month? For me, I enjoy creating environmental protest paintings. They tend to look more like posters and typically each one reflects upon a single environmental issue, although I have presented up to a dozen such paintings within a solo gallery show, under the title “Our Changing Planet.” If interested, you can view one of my science-subtitled slide shows on my website.

So, here we are, only a month away from April, and the start of Earth Month. I am busy creating new environmental protest paintings (my painted posters) and looking for opportunities to both share my work and hopefully stimulate others to draw on their own creative muse and engage in this fight for the very survival of our Blue Jewel, planet Earth!

Will you join me and others around the world and create and share your personal protest against one or more of the environmental wounds we humans have caused to our home in the stars?

Here is an Earth Day protest poster that I just completed, entitled “Replenish The Earth.”

The Wood Wide Web – Fruitful Collaboration

Artists Michael Gresalfi and Eva Strautmann‘s collaboration responds to our emerging understanding of the Wood Wide Web that connects trees, fungi and soil: networked communities threatened by our ‘competitive’ view of life and by our industrial forestry practices.

An interspecies symbiosis driving biological innovation

Below, Michael discusses the role of the Wood Wide Web. First, he
picks up the story of his and Eva’s collaboration:

When Eva and I began to discuss the continuing degradation and disruption of Earth’s regulating systems, we talked about the loss of habitat, and the largely unseen yet growing damage to co-evolved symbiotic relationships between different species. This discussion, and our shared love of forests, led us to our decision to focus both our attention and our art on the so-called ‘Wood Wide Web’.

We both independently created art that represents our artistic visualisation of this incredible symbiotic relationship between fungus, plants and trees.

The scientific community has confirmed many examples in nature of symbiotic relationships between animals, plants, insects, bacteria and fungi. In fact, we can look inside ourselves and find somewhere between one and three pounds of bacteria within our own large intestine: a relationship that scientists have termed a ‘mutualistic symbiosis’.

The surprise to me, when thinking about the so-called Wood Wide Web is both the complexity and the elegance of this mutualistic symbiosis between such a wide range of disparate species. Over the past 500 million years, fungi have co-evolved, along with plants and trees, to the benefit of all in this mutually supportive network.

I would contend that interspecies symbiosis is not just a common evolutionary path; that it is arguably the dominant engine of biological innovation on Earth. Today, roughly 80% to 90% of all land plants rely on fungal symbioses to survive. Without this cross-kingdom partnership, our forests and agricultural systems would collapse and the web of life itself might not exist.

Unfortunately, humans continue to cause such cross-kingdom partnerships to collapse, including the wood wide web. In fact, we have caused many such interspecies relationships to become ‘dysbiotic’.

Conversation with trees

Eva shares her reflections on producing her series as part of the collaboration with Michael:

‘Conversation With Trees’ is a very personal and, at the same time, professional way of viewing my surroundings.

Living in the city, in the mountains of stone, is loud, noisy, exhausting and painful. I can not hear any Voice, just ‘Trash’ and ‘Crash!’

Outside, in the countryside, on the sea, and in the forest, you can listen to the silence, to the movement of water, of ice, of the wind and you can listen to the trees.

This is what I have been doing for years and years, this is actually my home and my inner garden.

The movement of one tree or two or three … is telling me about the day, about friends, who are coming or not, the trees tell me about myself. What I wish, why and why not.

And there is one favourite tree right here, next door to my house, he is a bit nervous about my work: Eva, you are working too much. He keeps on telling me what is better for me. Some more coloured trees tell me about my next steps, what I should do.

I do not want to say here and now what I am telling them, but I am always polite and friendly.

Soon my friend Jacob Strautmann from Boston (USA) will write poems to my paintings, maybe he can describe my works.

These three paintings are the beginning of a series ‘Conversation With Trees’, which started in the dialogue with Michael. Our Zoom session and emails were very inspiring and helpful. I am very thankful to Michael and Mark: Thank you!

Mutualism & communication: life as an interconnected community

The Wood Wide Web portrays a forest not merely as a collection of competing individuals, but as an interconnected community where cooperation, sharing, and communication play a significant role in the health and resilience of the entire ecosystem. Science has revealed that trees in a forest are linked to neighboring trees by an underground network of fungi that resembles the neural networks in the brain.

These fungi form a symbiotic relationship with plant roots. They extend tiny, thread-like filaments far into the soil, acting as an extension of both tree and plant roots and can link the root systems of multiple trees and plants, often across different species.

The network between fungi and trees acts as a conduit for transferring resources like carbon, water, and nitrogen between neighboring trees. Trees, through photosynthesis, produce sugars (carbohydrates) and transfer some of this essential carbon to the fungi. Plants and other producers convert carbon dioxide from the atmosphere and water into carbohydrates (like glucose) using light energy. This process fixes atmospheric carbon into an organic, usable form.

The core of the Wood Wide Web is a biological partnership called mycorrhiza, which means ‘fungus-root’. Mycorrhizal fungi form a symbiotic relationship with plant roots. They extend tiny, thread-like filaments called hyphae (collectively known as mycelium) far into the soil, acting as an extension of the tree’s root system.

These fungal filaments can link the root systems of multiple trees and plants, often across different species, creating what is known as a Common Mycorrhizal Network (CMN).

The mycorrhizal network is believed to enable several vital functions. Resource exchange (mutualism) is the foundation of the relationship:

    • From tree to fungi: Trees, through photosynthesis, produce sugars (carbohydrates) and transfer some of this essential carbon to the fungi.
    • From fungi to tree: The fungi, in return, use their extensive network of hyphae to scavenge for water and crucial soil nutrients (like phosphorus and nitrogen) that are often inaccessible to the tree’s main roots, and transfer them back to the tree.
    • From tree to tree: The network can act as a conduit for transferring resources like carbon, water, and nitrogen between neighboring trees. For instance, a large, well-lit ‘mother tree’ might transfer nutrients to shaded seedlings or stressed neighbors, including its own kin.

Communication is another feature of the web. Some research suggests that trees can send chemical or electrical distress signals as warnings through the network — for example, when under attack by insects or disease — prompting neighboring plants to increase their own defensive enzyme production.

In essence, the Wood Wide Web portrays a forest not merely as a collection of competing individuals, but as an interconnected community where cooperation, sharing, and communication play a significant role in the health and resilience of the entire ecosystem.

Wood Wide Web research — diversity & resilience

The Mother Tree Project is a large-scale, long-term research and outreach initiative led by Dr. Suzanne Simard at the University of British Columbia. It is essentially a real-world experiment in regenerative forestry, building directly upon her decades of research into the Wood Wide Web.

The project’s goal is to find new, sustainable forest management practices that maintain forest health and resilience in the face of accelerating climate change, wildfires, and other disturbances.

Dr. Simard’s research on the Wood Wide Web and Mother Trees has been one of the most significant forces challenging conventional, industrial forestry practices that were largely based on a Darwinian view of tree competition.

Her field studies revealed that trees are linked to neighboring trees by the underground network of fungi described above, which resembles the neural networks in the brain. In one study, Simard watched as a Douglas fir that had been injured by insects appeared to send chemical warning signals to a ponderosa pine growing nearby. The pine tree then produced defense enzymes to protect against the insect.

Simard’s work proved that our aggressive removal of ‘competitors’ actually harmed the desired trees, as the clearcut seedlings were disconnected from the vital mycorrhizal network and the resources provided by the Mother Trees and neighboring species.

Both plants and fungi associate with multiple symbiotic partners at once, and both plants and fungi are capable of preferentially allocating resources to one partner over another.

Her findings advocate for promoting diversity, keeping a mixed-species forest and protecting the oldest, most-connected trees to ensure the entire ecosystem remains resilient.

Mycorrhizal associations have profoundly impacted the evolution of plant life on Earth ever since the initial adaptation of plant life to land. In evolutionary biology, mycorrhizal symbiosis has prompted inquiries into the possibility that symbiosis, not competition, is the main driver of evolution.

To inform his and Eva’s collaboration, Michael compiled information on the Wood Wide Web from data extracted using AI (Genesis).

The Mother Tree Project was established in 2015 by internationally acclaimed author and University of British Columbia ecologist Dr. Suzanne Simard, to address the urgent need to steward and safeguard British Columbia’s forests amid intensifying climate threats.

Michael also highlights this paper by Lucette Flandroy & colleagues: The impact of human activities and lifestyles on the interlinked microbiota and health of humans and of ecosystems (Science of The Total Environment, Volume 627, 15 June 2018, pages 1018-1038).
