an adventure deep into ‘the living forest,’ with joan maloof (book giveaway)

I’VE BEEN ADVENTURING deep into the forest, with what feels like a fresh sensibility, a whole new set of eyes, I guess you could say, thanks to the collaborative effort by photographer Robert Llewellyn, and environmental scientist Joan Maloof. Their new book is called “The Living Forest: A Visual Journey into the Heart of the Woods.”

Coauthor Joan Maloof is founder of the Old Growth Forest Network, aimed to preserve, protect and promote the country’s few remaining stands of old growth forest, and she’s a professor emeritus at Salisbury University in Maryland. She joined me to talk about complex the organism that is the forest, and I learned how almost half of all our rain is dependent on the forest’s “exhale” of water, how the trees with all their light-detecting cells can “see” different colors and intensities of light and respond accordingly, and much more.

‘the living’ forest, with joan maloof

 

Q. What a productive year you’re having, Joan.

A. I know, it’s crazy. “Nature’s Temples” came out just exactly a year ago, and then already “The Living Forest.”

Q. How did this matchup between you and photographer Robert Llewellyn come to pass?

A. I had already met Robert Llewellyn, because we have a lot of tree people that support the Old Growth Forest Network in Charlottesville, Virginia, and Robert Llewellyn lives just outside of Charlottesville in this beautiful property surrounded by acres of forest. He has done books, such as “The Remarkable Trees of Virginia,” and “Seeing Trees,” and “Seeing Flowers”—these amazing photographic works.

With the Old Growth Forest Network, at one point we wanted to use one of his images, the one of a tiny oak seedling sprouting from an acorn with the roots there. It seemed like the perfect thing for our young little organization. We wanted to grow strong and mighty as an oak, but we were just getting started. I just gave him a call and he got the on the telephone and said yes, we were welcome to use that for no cost, so that was very nice.

The next time I was in Charlottesville giving talks, I went to visit him personally, and we talked about forests, and his photography, and I got to see his incredible studio, which is like a museum. We developed a relationship that way and a conversation about forests. I read his books, and he read my books. I was working on the book “Nature’s Temples,” which I call it my science-y book; we’ve talked about it before.

Q. Yes, we have talked about it, yes. [Read or listen to that interview on old-growth forests.]

A. It has the evidence for the biodiversity in old-growth forests, and I was awarded a writer’s retreat to live in Southern France for a month to work on that book, the draft of that book. That was a great experience, as you might imagine. One day I got a call from the States, and it was Robert Llewellyn, and he said that he was inviting me to be the writer on his next book, which was going to be an exploration of the Eastern deciduous forest ecosystem. Of course, I was thrilled, and immediately said yes, I will do it.

Q. Yes, yes!

A. Just as soon as this other one’s done, and it was almost done, so that’s how I ended up with two books back to back so quickly.

Q. We’ve spoken before, as we were just saying, when your previous book “Nature’s Temples” came out. The latest book, “The Living Forest,” is big. It’s big in size, it’s big in subject matter, but at the same time it’s sort of very intimate and full of these tiny little details like, there’s delicious pictures of millipedes [photo below] and salamanders and fungi, all kinds of things that most of us visiting forests might not have noticed, or at least not understood. What was the mission of the book, and how’s it different from the ones you’ve written previously?

A. With the previous books, when we looked at forests and how we’ve treated them in this country and in the world, there can be a lot almost sorrow or regret, or feel like we’ve made some mistakes, and the evidence shows that also.

But this book I wanted to be the opposite of that. I wanted this book to be the celebration for how the forest does work perfectly as this integrated ecosystem all on its own. In this book I stayed away from all the gloom and doom and just focused on the rightness of it. As you pointed out, the scale was very important in this book, because it goes from the largest of the large—these beautiful forested vista and the Smoky Mountains, and the Shenandoah—all the way down to the tiniest little thing in the soil.

It was quite a challenge in the beginning: How do we tell that complete story of a forest that’s connected in so many different dimensions, and scales, and even through time. That was part of the joy of crafting this holistic type story, and drawing attention to all these connections. Robert had the skills to be able to do that on every level, which was remarkable also, because often photographers will specialize in either the very large or the very small, or in the middle somewhere. He has the full range of talent and equipment to deal with it.

Q. That’s why I said I think it feels very big, because you’re seeing from the canopy, you’re looking down into herons’ rooks. Rooks, is that what they’re called?—nests of herons.

A. The rookery of the blue herons, yes.

Q. Then you’re crawling around down below with the little creatures I was mentioning before, and you’re at the roots. You’re all over the place.

A. Even at one point, because he had provided me … he’d been already photographing for two years by the time he invited me to write this. He gave me folders full of these amazing photographs. This is the raw material of it, which I drew from to put all this together, but still, there were certain places where I thought, oh, I want to talk more about the larval salamander, or I want to discuss the stomata, the pores and leaves.

I also gave Robert this list of things that we needed in addition. [Laughter.] He went on these, he called them treasure hunts, and he got people to help him, and then went on treasure hunts. For example, I said, “We need a closeup of a leaf, super-closeup of a leaf,” so he gave me a closeup of leaf. I said “We need it closer,” and he gave me a closer one. I said, “We need it even closer. Do you have a microscope?” He says, “I do!” For that one we finally got so close that we could see the pores on the leaf, and we used a microscope to do that, and ended up providing a beautiful image for that.

Q. When you said you wanted stomata, you meant you wanted them. [Photo below.]

A. Yes.

Q. You weren’t kidding around.

A. We had so much fun then, because Robert knew in theory that the leaves had pores that did all this work, but he had never seen it with his own eyes through the microscope, so there he was looking. He got to see things in a new way, and he was just amazed at how there were like little mouths that control so much of our atmosphere.

Q. One of the chapters in the book is called “A Deep Breath,” and you’re making me think of that chapter just as you’re speaking right now. Let’s talk a little bit about that, about how is the forest taking a deep breath? Or maybe it is a deep breath—the organism is a deep breath.

A. On so many different scales, right? Also, because it could be the deep breath of that individual little stomata that’s opened all the way going, “Oh conditions are just right, I’ve got plenty of water and the sun is shining, and I’m just going to go for it and open this pore all the way, and exchange as many materials as I can,”

To the deep breath of the whole forest. That would be things going in and out of those stomata all at once. The inhale of the forest during the daylight hours would be the inhale of Carbon dioxide, and those leaves are taking that in because the Carbon dioxide is the basis of those sugars that it builds with photosynthesis, and then stores in all of the wood that we see, all of the flowers, and all of the leaves that’s actually making the forest. The inhale of the Carbon dioxide, and if we could measure—well, we can measure the Carbon dioxide in the forest—and we could see that it drops down in the daytime when the forest is taking that inhale, and then it goes back up at night when the forest cells are continuing to work, but they’re not doing photosynthesis.

The other part of that forest breathing has to do with the water vapor. We know that those roots are taking in water, and drawing it all the way up the stem in those vessels, all the way out to every leaf cell. Only 10 percent of that water is used in the photosynthetic process. 90 percent is just lost out of those pores. We say lost, but I should say emitted. That water vapor enters the atmosphere and is carried aloft where it cools off and then will be carried on the prevailing winds, and turn into rain somewhere else for another forest.

Q. Yes.

A. It’s beautiful, I mean talk about large scale. Now, we’re on the global scale there. Almost half of all our rainfall is dependent on this forest exhale of water.

Q. I think the subhead of that chapter “A Deep Breath” is “Lungs of the Land.” Indeed, right, that’s what the forest is.

I live in a surrounded by this 7,000-acre state park, sort of a forest, adjacent to another one across the state line, just beyond my house, and lots other privately held large tracts of wooded land. I’m not a stranger to the woods, but when I was looking at it with you two, you and Robert as my guides, paging through this book and reading this book, it really felt different, as if it was much, more than the trees.

I mentioned some of the other creatures, but even just when I looked at the trees in the pictures, they just seem different to me. How do you describe the forest? We just said it’s the lungs of the land, it’s a deep breath, but what else, what are some of its other aspects?

A. One thing that I like to emphasize is that a forest is more than just trees, right? We’re talking about the trees, and we tend to think of the trees, but the trees are really more like the bones, the structure.

Yes, we need that structure of the forest, those big bones to give it the dimensional qualities, but there’s so much more happening than just the trees. There are the insects that feed on the trees, and the reptiles and amphibians that feed on the insects, and the fungi that’s growing underground and occasionally sending up a mushroom that then is eaten by a snail, or by a turtle. The lichens that are growing on the rocks that are shaded by the trees.

In this book, we try to include all of those dimensions of the forest. It’s one thing to just say that the forest includes all those dimensions, but then when we are able to capture in visual representation, like in the photographs, one of the parts of it—whether it’s the lichens or the snails or the turtles or the mushrooms—then that itself becomes a place where we can recognize the beauty of the forest, which is another whole layer as far as what it does to us emotionally.

When I walk through the forest, and I would suggest this to others; yes, appreciate the trees and the individual trees, but try to feel the whole. And also try to leave yourself open for those moments of surprise, whether it’s the pattern of a root across a rock, or the most perfect fall color pattern you’ve ever seen on a leaf, or whatever it is. Leave your spirit and energy open for appreciation.

Q. Speaking of little surprises that I found along the way, I learned so many things that I’ve wondered about and I’ve asked people about, and I couldn’t get a clear answer. I got the clear answer, so it was a happy surprise.

For instance, that you just mentioned fungi. Where I live there’s a lot of evidence, in the older trees especially, of the shelf fungi [photo above]. I had also, a million years ago, heard the word conk, and I didn’t know what was the difference between a conk and a shelf fungus. Sure enough you explained, the ones [photo below] that are sort of shaped like hooves, like an animal’s hoof that are sort of downward curved, those are the conks. It was little things like that, again, that was like that intimacy, that you were teaching me not just the look, but you were giving me the language.

Another thing I’m crazy about, moths. A lot of people don’t go into the forest at night, it might seem scary or whatever, but moths are one thing that you’ll see if you go out at night. I didn’t know how they escaped from being eaten by bats. I can’t hear bats, except for maybe some clicking occasionally in certain species I think you can hear. Bats with their echolocation, their sonar, whatever is, I guess the moths can hear that?

A. Yes, some moths can hear that. They can avoid the bats, and some can even jam the radar of the bats and trick them, and make their own little sounds that we can’t hear.

Q. Everybody’s trying to get a meal, everyone’s trying to survive until tomorrow, everybody’s feeding and also offering themselves as food in some way. It’s just this community of interdependence. I think that’s really what I got a lot of detail in the book. I want to ask you about another chapter, the chapter called “Eyes All Over.” Eyes, E-Y-E-S, if people are listening, not reading. Can we talk about your assertion that trees can see? [Laughter.]

A. Sure. [Laughter.]

Q. O.K. Joan, tell us about this now.

A. We’ll start with our eyes. We have these parts of our bodies that are sensitive to light, and how we see light? We have these cells in the back of our retinas that contain pigments, and when this light hits these pigments, then it causes a reaction, a change in another molecule that can send a message. In our case, to the neurons to our brain saying, “Oh, you saw something; you saw light.” Also, the light that we see can also affect our hormones. As we know, if people suffer from Seasonal Affective Disorder, SAD, some people this time of year are just starting to feel that perhaps coming on. That is the reaction to what is coming in through our retinas, or not coming in.

When you look at—we’ll talk about trees this time—a tree leaf, each of those cells in the leaf contains in this green leaf these pigments that are light-detecting. Light is so important to the plants, that’s how they make their food.

Q. Right.

A. These pigments, just like the pigments in our eyes, change structure depending on what type of light is hitting them, and that causes a reaction also in the plants, the same way we have a reaction. Instead of it going through their neurons and to their brain saying “You’ve just seen something,” instead it goes directly to the hormonal system of the plant. The plant will produce certain chemicals, hormone chemicals, depending on how much light they saw, how many hours in a day, or whether it was green light or blue light, because these photosynthetic cells can tell the difference in the wavelengths, the quality of light.

A leaf knows if it’s being shaded by another tree or by a building, depending on the wavelength that comes through. It also knows if it’s mid-day or early morning or late afternoon, depending on the quality of the wavelength.

I don’t want to get too geeky about this, but extrapolating in my mind—my mind says O.K., if these plants can sense these wavelengths, and they’ll do certain things depending on the wavelengths, like make berries or change colors or drop their leaves. That means if I wear a red jacket into the forest, that’s reflecting a different wavelength than if I wore a black jacket into the forest. In a way, although I haven’t read the scientific data on this specifically, I think the photosynthetic leaves can also sense the colors that we present to them. That’s how the forest is seeing us, too.

Q. Oh boy, so the plant knows the season of the year, and the time of day, and the intensity and so forth. Like you say, where the light fits into the spectrum, all the different qualities of light in the same way that we do.

A. Exactly. We can close the window shades, or open the door, or flip on a light switch. The trees can’t do any of that, but they do respond, they respond ever so slowly, and only by the process of growth. The response could be chemical that will cause a change in growth, it’ll cause the berries to form, the berries to ripen, the buds to form. Or, it will cause the branch to grow in this direction and not the other direction. It’s a response, but it’s a very slow and graceful response.

Q. I guess I want to ask you something about fall, because here we are. The leaves have been going and going and going. I’m in the North.

A. Going, going, gone. [Laughter.]

Q. Yes. Sometimes they don’t fall, all of them don’t fall. One of my favorite words is the word marcescent, I think that’s how you say it.

A. Yes.

Q. People might see in oak trees where the leaves are withered, they’re brown, but they stay up there. Tell me something about leaves falling—or not.

A. The usual pattern in a deciduous tree, those are trees that drop their leaves, are that the color changes, the green pigments get recycled the red is actually like a sunscreen pigment that’s made to protect the leaf. Eventually, and again this is a response to the trees seeing the light and knowing if fall’s coming, they will produce a layer, like a scar tissue, at the very base of the leaf. That will eventually cause the leaf to break off right at that point, at the base of the petiole.

Some trees as you know, like the oak, and also the beech, they don’t drop their leaves in the fall. They’ll hold onto their brown leaves, and usually drop them in the spring. We don’t really understand why there’s that difference, but we know that there is. Some people have speculated that with the beech trees, that the dry, dead leaves may make them less tasty to the deer that might want to browse them.

Q. Yes, I’ve read that.

A. I thought that was very interesting. Again, we can just appreciate it with our hearts and spirits, too, and see how beautiful they are. If you have a tree, like a maple that normally would drop its leaves in the fall, and that doesn’t happen, that’s a signal that something has gone wrong in that system, because that tree normally should have made that abscission zone that caused the leaf to drop off. Sometimes it’s what the plant normally does, but sometimes it’s unusual.

Q. Leaves fall, and sometimes they don’t.

  1. Peggy says:

    I am lucky to have a small woodlot in my backyard so get to walk through it everyday. My spirits always rise after walking in a forest. I have walked through many forests for my job throughout the USA. Now that I am retired I like to find new to me ones in foreign places.

  2. Pat McCorkle says:

    I live on about 30 acres in Wisconsin and I walk in the woods most days. Much of our land is wooded….many big oaks. I was chanting early one morning not long ago, facing west behind a glass wall when I witnessed a huge oak toppling. In slow motion, it fell, missing the house and taking down another tree or two. That was both the most majestic and the saddest thing I’ve seen in a long time.

  3. I grew up on a gorgeous piece of woodland In Killingworth, CT full of glacial stone, beech trees, wild ramps, ferns and more. However, My last walk in the woods was yesterday on a public trail thorough Hammonasset State Park inMadison, CT.

  4. Conrad Szablewski says:

    Where I live has plenty of wooded areas and are a pleasure to be walking in. The serenity they bring can not be equaled.

  5. Nona McQuay says:

    I last walked in the woods 3 years ago but my mobility is limited now. It was a magical tour as the 80 foot tall wild cherries suddenly dropped their blossom petals as I stood all alone at the end of the tour group. We were honoring the Land Conservancy for their purchase of forest on the Niagara Escarpment, a 750 mile land mass in the US and Canada. This woods will be there for others in the foreseeable future.

  6. Margo Greene says:

    Maine has wonderful forests that are easy to access. My last hike in the woods was at Fernald’s Neck
    Preserve. It takes you around part of Lake Megunticook with beautiful views. The woods are magical with their old growth pines and rocky outcrops. The peace and tranquility that comes from hiking these trails is priceless.

  7. Meg Ryan says:

    Just last weekend I walked through the forest to Shark’s Reef, here on remote Lopez Island, Wa. My husband, daughter, son-in-law and grand toddler joined me and we regaled at all the lichen, nursing logs, 6′ tall salal, ferns, conifers but with a scattering of alders, and a fistful of fungi we passed. My grandson, being a city boy, had never seen such beautiful nature.

  8. Kathy Paul says:

    I walk my own property, although maybe not a deep forest, does include about 3 acres of woods. I’m humbled with every walk, always seeing something new and uniquely beautiful.

  9. pj says:

    My sister took me to the woods in Rowley, Mass just last weekend. A typical old New England tract with moss covered stone walls where there likely used to be fields, now gone back to woods with some magnificent pine trees. It was so nice we lost track of the time and I almost missed my train. Thanks as always for your wonderful podcasts and interesting guests.

  10. Angie W says:

    The last time I walked through the woods was when we went on a hike a couple of months ago. However, I live in a very lush part of WA state so it feels like I’m always living in the woods.

  11. Doreen Tignanelli says:

    While we have old-growth trees on our property adjacent to a forested wetland, we lament the fact that our bouts with tick-borne diseases (Lyme and ehrlichiosis) keep us from enjoying the woods like we used to. It is so bad that our neighborhood in Dutchess County New York is part of a five-year study to determine whether neighborhood-based prevention can reduce tick-borne diseases. We do still enjoy the barred owls and pileated woodpeckers these large, old trees attract.

  12. Gloria Cunningham says:

    My most recent walk in the forest was yesterday at Assabet National Wildlife, which is very near my home. There are many pink lady’s slippers in late May. My husband and I have been wondering why so many leaves on the trees in our part of New England have just dried up on the trees and not fallen. I am assuming it is partially because of our drought last year and somewhat this Fall.
    I wonder if the author, Joan, is aware that there is old growth forest on one side of Mount Wachusett? Years ago I hiked that (straight up!) with a naturalist. I would love to win this book!

  13. Susan Clarkson says:

    I love camping in the Sierras. I adore the tall pines. It is my favorite place to walk, sit, sleep, etc. Unfortunally, due to the fires we’ve had of late & some health problems, it’s been 4 years since I was there & I’m really missing it.

  14. Sarah Donnelly says:

    The day before yesterday-Thanksgiving Day-I took a short walk in our woods. The leaves are going fast, but some dogwood trees still had red leaves, The oaks had their semi-permanent brown petticoats. The beeches had theirs, too. Love watching the beech leaves slowly bleach out over the winter and then drop as if the are spring snow.

  15. M Dittmer says:

    Last January I took a two mile walk in the woods before I started cancer treatment. Mother Nature helped put everything in perspective. Later,memories of the maple and oak trees, grasses and birds helped get me through some challenging times. I look forward to regular walks in the forest this coming spring.

  16. Nancy Geryk says:

    I really like that you can read about the forest in wonder and not be confronted with all the terrible things we are doing to our environment. You have to love the environment in order to save it.

  17. Marianne says:

    Thank you for this wonderful interview! We are fortunate to be surrounded by forests of the Berkshires! Hopefully more people are moved to preserve our natural resources.

  18. Audrey Hite says:

    Along the edge of Maidstone Lake in Maidstone VT, so much to see that I was there to pick wild blackberries and was overcome with the beauty and bounty of nature.

  19. Mike says:

    I’ll definitely be getting this book regardless. The pictures are fantastic. And, I love the perspective of the whole big picture. I try to take in all the great things big and small so the book will just give me better appreciation of those things.

    All we have are woods around us in Indiana. I opted outside all weekend long enjoying the many birds in city parks around Indianapolis.

  20. Andie says:

    We walk in the woods behind our house nearly daily. This environs helped us raise two happy health kids who have grown to happy, well adjusted adult
    Fresh air is vital for a good life. And Life is Good

  21. OOOO! Love this! We are working on putting the forest back together here in Ohio on just our small patch of land, but the life returning…so quickly is astounding and heartening. :) We took a hike on Black Friday at two special places in Indiana…Fox Island County Park and Lindenwood Nature Preserve (the location of my first naturalist job out of college – oh my heart!). We head to Mohican State Park and State Forest in Ohio on Tuesday of this week and somewhere else soon after that. We can’t get enough!

  22. Christa says:

    I’m visiting in Michigan now, and notice that the oaks have retained many more of their leaves here than near my home on the coast of Maine. I wonder what will happen to those oak branches if they must bear the weight of ice and snow… so many things to wonder about, and this book looks like it will spur more questions as well as answers!

  23. Jan Vallar-Gillette says:

    Played as a child in the woods in Maryland and learned to appreciate the beauty of every natural thing. Nowadays I spend time walking in Lincoln Memorial Gardens, a wildlife sanctuary near Springfield, IL This book has some of the most scrumptious images in its pages. It is a feast for the eyes!
