Introduction

How I Got Here

I had been woken by a sudden downdraft of air that left my hammock gently swaying. Lying on my side, I stared in drowsy amazement at the huge prehistoric-looking bird that had just landed next to me. The two of us were two hundred feet off the ground in the top of a tree in Borneo, and I’d never seen a rhinoceros hornbill so close up before. It hadn’t noticed me yet and was using its long beak to preen its breast feathers. A huge colorful casque curled up from the top of its head like a flamboyant Turkish slipper—fiery reds and yellows glowing brightly in the half-light of dawn. I was entranced.

A few seconds later it froze, then raised its pterodactyl head to peer at me with a ruby-red eye before launching off the branch into space. Immense black wings unfurled to catch its weight and it was gone. Swallowed in an instant by the thick morning mist.

Rolling onto my back, I lay staring up into the giant branches above. It had been a long night. The sweat from yesterday’s climb had long since congealed into a clammy grime all over me. My clothes were dank, gritty, and torn, and my skin crawled with biting ants. I had a burning rash on my chest from who knows what, and I’d been stung twice on the face by a night wasp sometime around midnight. But it was worth it—all of it. Encountering a hornbill like that was what it was all about. I was immersed in my very own dreamworld of swirling mists and fairy-tale creatures. There was nowhere else I’d rather be.

The sun hadn’t yet risen and I was cold for the first time since arriving in Borneo, a welcome change from the usual stifling heat of the rainforest. Sunrise couldn’t be far off, but for now I was happy to lie back and watch the individual droplets of water drift past. They swirled in the visible currents of air, condensing as shiny beads on the metal of my climbing gear. I had slept in my safety harness attached to a rope, my only direct link to the other world far below.

 

YESTERDAY’S CLIMB had been nothing short of a mission. Borneo is home to the tallest tropical rainforest on the planet, and many of the hardwood trees here are well over 250 feet tall, frequently with no branches for at least the first 150 feet. Tall, straight columns of wood that support enormous parasols of branches high above. Just getting a rope up into them was often nearly impossible.

Experience had taught me that my catapult could propel a 200-gram throw-bag 170 feet into the air. But time and again the bag fell short of its target branch, the thin line it towed floating back down to tangle in the understory, slack and lifeless. The branch was clearly much higher than I had realized. In exasperation, I attached the catapult to the top of a ten-foot pole and used my body weight to pull the creaking elastic right down to the ground. My muscles shuddered as I crouched, taking aim at the branch high above me. As I let go, the catapult’s elastic cracked like a whip and tangled into a limp coil. Its job was done; I dropped it to the floor. The bag powered up through the gap in the dense understory to skim over the top of the target branch, with barely inches to spare. Then down it came, the line accelerating into a high-pitched whine as the bag finally embedded itself in the leaf litter with a dull thud. All was quiet again. I squinted up through my fogged binoculars, tracing the thin line against the bright tropical sky high above. It was a good shot, at last.

I used the line to thread my climbing rope up over the top branch and back down to the forest floor, where I anchored it securely around the base of a neighboring tree.

The start of a climb up into a monster like this is always a slow, laborious affair. Most of your energy is soaked up by the elasticity in such a long rope. There was around four hundred feet of it in the system, so I bounced erratically as the nylon stretched and contracted. It was impossible not to careen into the huge buttress roots, and it wasn’t until I was a good way up that I was finally able to brace both feet against the trunk and get stuck into it properly. I inchwormed my way upward, using two rope clamps, or jumars, to haul myself up the thin nylon line. Rhythm is key in climbing, and it always pays to synchronize yourself with the rope’s natural bounce. But it was going to be a long haul regardless. My arms were already knackered from the struggle to get a line up in the first place, so I used my legs to push myself up in an attempt to take the strain off my biceps.

The next challenge was to get up through the forest’s tangled understory. Vines grappled me like tentacles and leaves brushed across my sweaty face, depositing dust and algae in my eyes and ears. The sheer amount of organic debris hanging around in these lower levels beggars belief. Decades of accumulated dirt, dead branches, and rotting vegetation are hanging there, snagged in a web of foliage just waiting to be dislodged. This first fifty feet was a filthy fight. Debris rained down in mini avalanches to cling to my sweat-soaked clothes, and every twitch of my rope showered me with fine black compost from above. But there was no alternative route; all I had was the straight line of the rope above me. By the time I emerged into the open space above, I was caked in dirt.

Although it was late afternoon, I was hit by the full force of the tropical sun as soon as I poked my head above the understory. For the next hundred feet there was nothing except open space and the monolithic tree trunk next to me. This branchless region is a strange limbo world where climbers are fully exposed to the precariousness of dangling on a nylon thread high aboveground. Concentrating on the brown, flaky bark in front of me, I slowly pressed on toward the sanctuary of the canopy.

Ten stories aboveground I was halfway up and the tree trunk still measured five feet in diameter. These Borneo trees are on a different scale to any other hardwoods in the world. I spun around to take a look at the view. I had been saving this moment until I was way above the understory, in a place that would do it justice. But I had felt its presence lurking behind me the whole time as I climbed. An almost palpable, brooding watchfulness, as if a thousand pairs of hidden eyes were boring into me from the surrounding jungle.

As I twisted around, I was greeted by one of the most breathtaking views I’d ever seen. Dense rainforest swept away from me, cascading steeply down from the ridge to merge into an enticing landscape of giant trees far below. Many miles away on the horizon, the forest rose back up to swarm over a ridge of tall, rugged hills. A vast ocean of unexplored, virgin jungle. What hidden wonders lay out there in those trees?

I was now hanging in the full glare of the sun and could feel the sweat trickling down my spine between my shoulder blades. The air was heavy with humidity and I could hear thunder in the distance. By the time I raised my arms to take the next step, my shirt was soaked through and sticking like plastic wrap. I pushed on, up into the dappled shade of the canopy above. Soon I reached my branch two hundred feet above the ground, and panting as I slung myself over it, I removed my helmet to reduce excess body heat.

The next twenty minutes were spent rigging my hammock between two horizontal branches. By the time I rolled into it, slumping in an exhausted heap, the light was fading fast. The peals of thunder, distant at first, started rumbling louder and faster. Before long, the heavens opened, and sweet, heavy rain fell into my cupped hands as I washed the grime from my face. The water tasted metallic and zingy. Almost electric, it was so pure and fresh. The rain lasted only half an hour or so, but by the time it stopped there were several inches of water swilling around in my hammock with me. So I rolled to one side and tipped it glistening over the edge to the forest floor far below. Even before it was dark I had slipped into an exhausted deep sleep devoid of dreams.

Apart from the incident with the wasps at midnight I had slept well. The mist was thinning, and high above I could see the first hint of blue. It was going to be a clear sunrise. It felt decadent, lying back with nothing to do but wait for the slow arrival of the new day. Cocooned in my misty world, I found myself asking why I had felt the urge to sleep a night in this tree, of all places.

It certainly wasn’t for comfort. I’d slept in my climbing harness and eaten all my food ages ago, so was now ravenous. I’d also been bitten and stung by so many insects I felt like one big lump of histamine. And yet I was at peace. Completely at peace with myself and the world around me. But why? What was it about climbing trees that was so appealing and resonated so deeply? And how on earth had I managed to make a living from doing it?

 

THE REASON I was in Borneo was to teach scientists how to climb trees, showing them the ropes—literally—and going over the drills until they could climb safely under their own supervision. They were out here to study the relationship between our planet and its atmosphere, doing incredibly valuable work mining the forest for data to fight climate change. Their research was inspiring and important.

But although I enjoyed teaching them, it wasn’t really why I was here. I hadn’t needed a reason to come and climb. My own passion for climbing trees was harder to define, born from something I had felt the first time I’d climbed into the canopy of that oak in the New Forest as a boy. There’s just something about trees that enthralls me and keeps me coming back to spend time with them.

In many ways, I feel that they embody the very essence of nature. Providing us with a living connection to our planet, somehow bridging the gap between our own fleeting lives and the world around us. I feel I’m being offered a glimpse of a half-remembered ancestral world when I climb into them, and for some reason this makes me feel good. It helps me remember my place in the scheme of things.

But above all, my enjoyment flows from a deeply rooted belief that every tree has a unique personality that speaks to the climber who is willing to listen. Whether the soft shimmering glow of a beech canopy in springtime, or the vast sun-blasted canopy of a tropical giant, each tree has a unique character, and it is the privileged feeling of getting to know them a little better—of physically connecting with them, if only for a short while—that draws me back into their branches time and time again. I believe that as living ambassadors from the past, they deserve our deep, abiding respect, and I’m willing to bet that most of us have experienced an emotional connection to them at some point in our lives.

 

MY PASSION for tree climbing was also born of a keen desire to discover the wonderful things held in their branches. There are entire worlds within worlds hidden in even the smallest of trees, let alone the huge forest giants like the one in Borneo I was currently lying in. The canopy is home to myriad creatures that never touch the ground, spending their entire lives up here. Hunting, feeding, breeding, living, and dying in an unseen treetop realm. Immersed in an endless cycle of secret dramas that have played out over and over again for millions of years.

A face-to-face encounter with an orangutan twenty stories above the rainforest floor can be a humbling experience. But the branches of trees closer to home hold just as much fascination for me now as they ever did. I still vividly recall the delicate translucent green of the first bush cricket I saw in the canopy of the New Forest, marveling at the way it leapt off a leaf to float down through the void, with its impossibly long antennae spread like the arms of a tiny skydiver.

It was a desire to share these experiences and help reveal this unknown treetop world to others that led me into natural history filmmaking. Photography and tree climbing went hand in hand, and by the time I was sixteen I was determined to be a wildlife cameraman.

But when I eventually left college and university, it quickly became clear that a degree was no substitute for practical camera skills, and I still had a lot of learning to do. So I took whatever camera assistant jobs were offered, and worked for free in exchange for experience, doing night shifts in factories and anything else I could find to tide me over. There can be few jobs quite as demoralizing as collecting the wind-blown litter from fences around landfills, so I was extremely relieved to eventually be offered my first paid assistant role on a production in Morocco. A couple of years later I’d saved enough cash to make a tentative move to Bristol—home of the BBC Natural History Unit—where I began to find demand for my tree-rigging and assistant skills. My eventual transition from assistant to cameraman took a long time—about ten years—but it was an incredible journey, and I enjoyed every step of the way.

So even though I now struggle to figure out how on earth I ended up where I am, the bottom line is that I am profoundly grateful and simply can’t imagine doing anything else. And whenever I feel the inclination to grumble to myself while getting stung and bitten by insects as I film from a camera hide a hundred feet aboveground in the jungle, I consider it a duty to give myself a metaphorical slap around the face just in case I’m tempted to grow complacent and take things for granted.

As much as I love the camera work, beneath it all still lies my enduring passion for trees. Deep down I know that however I had chosen to make my living, I would still be out climbing trees in an effort to get as close to them as possible.

I climbed my first big tree with ropes when I was sixteen. The intervening years have raced past in a tangle of branches and foliage, and I must have climbed enough trees to fill an entire forest by now. But although many have blurred together, there are others that rise above the fog of memory. Special trees that I remember spending time in as if it were yesterday. The touch of their bark, the smell of their timber, and the shape of their branches, not to mention the wonderful animals and people I’ve encountered in their canopies.

 

BACK IN the Borneo canopy, the air had warmed with the coming of the sun, and in the space of a few short minutes the mist had been pushed down into the valley to pool in one vast ocean of white. To my right the sun had just risen above the hills to set the valley on fire. The mist instantly began to rise in tendrils, glowing pink, orange, and gold for a brief instant before evaporating altogether.

Within fifteen minutes the sun was high in a clear tropical sky, and swifts were trawling for insects over the canopy. The new day had begun and I prepared to descend back to earth, back down into the gloom of the forest floor where night still lingered.
