Is Every Rotten Tree in the Forest Really Out to Get You?

The modern world has noticeably changed. We all have rights now; should a tree fall upon us somebody else will almost certainly be  responsible, and if an appropriate scapegoat can’t be found we can at least expect to sue our local authority. There is very little left in the developed world for which we are responsible – becoming fat, having too many children, getting run over when jogging across a busy intersection whilst listening to a stereo system plugged into our ears; even spilling hot coffee over ourselves in a public place clearly has nothing to do with us. Read the warning on the cup: ‘The beverage you are about to enjoy is extremely hot’. Personally, I wouldn’t risk it – a juice perhaps – but wait… there’s no diabetes warning – how irresponsible is that?

Whatever stupid thing we might choose to do is done with the understanding that when things go wrong it will always be somebody else’s fault – it falls to the authorities to protect us from every idiocy we care to perpetrate on ourselves; but as we pass on our personal responsibilities, inevitably a lot else goes with them, not least our personal freedom. And if you think that natural selection is no longer operating at the human level with our now near total control of the environment, you’d be wrong, because we are now maintaining all the stupidest genes within the pool by a process of litigation. Who’s really responsible when a tree falls on us? And shouldn’t it be up to us on occasions to see a potential problem before it arises?

This sort of thing isn't impossible, but it's rare - in this case I'm feeling better than appearances might suggest... and photographing fungi.

My family and I now live in Surrey, British Columbia – we arrived around five years ago and it was then perhaps even greener than its leafy name sake in England. Both Surreys are well known for their tree filled suburbs – but something is very wrong with the one we now live in. According to a local report, the Surrey in B.C. has lost almost one fifth of its tree canopy in just over a decade and that isn’t very Canadian – most people here favour trees, which might seem a bit odd for a nation that not so long ago built an entire economy by cutting them down. Presently, it is the suburbs that are at the sharp end of the chop, and a large number of trees have been felled in recent years. Maybe fewer of us are bothered than was once the case, or it might just be that not enough people live in the same place for long enough to notice the changes.

Not long after arriving, I was photographing birds in a local wood when a passing local stopped to talk. I told him that I had seldom seen such a diversity of birdlife in a suburban area, and he responded by saying that if I thought that this was diversity, then I should have been here twenty years ago.

In some Surrey woodlands bird diversity and numbers have decreased in recent years.

That’s just the way things go; we move in, then move on and hardly notice the change. Or could it be that we just allow our brains to slip into a happy state of mind. If so, this rosy thinking may have long term consequences because decreasing wildlife diversity is a clear indication that we are heading for trouble. I’ve noticed an obvious decline in woodland birds during the five years I have lived here – it’s a sad situation, but I’ve seen it happen before.

Getting older provides plenty of time for bad dreams to repeat themselves, but it clearly isn’t up to me to decide which woodlands should be protected from development, although it is obvious that this kind of destruction can’t continue at the present rate forever. Every local should be entitled to a view, but unfortunately most prefer to moan after the event, and many Canadians are so pleasant, they hardly complain at all. Fortunately, I’m not so good natured, and will comment even if it’s a little late to make a difference, but perhaps by doing so I’ll help to change the future… and we could argue for days as to whether that’s remotely possible.

Some people say we have a natural fear of the forest, and that may be so, but inn general the woods are a safer place than the suburbs or the city where people tend to be a good deal more dangerous than vegetables.

So, I’m away from the area for a week and return to discover a great many of the trees in Fleetwood Park woods have been felled along the main pathway, and on almost every occasion I return there, more trees that have been cut down. To me this seems a travesty, but I’m not sure that others share my view – I feel like the character in a 1960’s horror movie who has walked into that lonely pub on the moor thinking something is wrong, but the locals don’t want to talk about it.

The forest isn't full of werewolves and spirit bears and at least somebody in these parts thinks we should 'be happy' out in the woods - and I am. It is only red dots on trees that get me down.

What is certain is that along the path a great many trees were marked with red paint and not long after, they were, and still are being cut down, probably due to a concern that one might fall onto the path, which occasionally happens, but usually this has happened at night during storms when the chance that somebody might be walking by is very low. Branches that fall directly from above in windy weather would certainly present a hazard, but there are none over the paths here, and a tree that topples directly onto somebody is unlikely in the extreme.

It is surprising how long a rotten tree will stand before it goes over and when it does, you have to be as rooted to the spot as the tree once was to get hit. A tree falling takes time and is a noisy process. There is a little sign along the nature walk to make us feel good – it reads ‘Nature at Work’, and that’s exactly what this is – so the best thing you can do is step out of the way – unless you’re one of those litigious people just waiting for the right opportunity to bolster family fortunes.

There can be no complaints about cutting this one - clearly a rotter and close by the path it needed to come down for safety reasons. In praise of the local authority, the felled timber is left to rot, which is essential to the long term well being of the forest.

The real concern is that many of the cut trees are not  dangerously rotten and there are a great many of them. It can take a hundred years and more for some trees to grow to a decent size, but only a few seconds to daub a blob of red paint on a trunk, with only a few more required to fell it.

This one probably could have stayed upright. When the edge of a woodland is cut, the tree line becomes irregular and there is good scientific evidence to show that the remaining trees become more vulnerable to an increase in swirling wind movement.

Until recently we were lucky enough to own a small wood; and from an upper window I could watch the effect of storms on a tree line close by the house. When a large tree was blown over, disturbance to trees further into the forest was clearly noticeable and sealing the forest border produced a marked improvement in tree survival. Shrubs and trees allowed to grow naturally along the margin will substantially stabilise a forest and it is surprising how effective even a five to ten year old natural windbreak can be in sustaining the interior.

Why cut these trees? It just opens things up and makes the wood more susceptable to wind damage.

I asked local people passing through the wood what they thought and most seemed unconcerned, and quite a few hadn’t even noticed – I can’t imagine how this is possible because it looks as if a battalion of tanks has driven through – apart from the obvious sharply cut tree bases, which didn’t seem at all odd to the man who thought the problem might have been caused by the wind. Another couple had other views: the man said cottonwoods didn’t grow nicely and  he’d like to see them replaced with conifers which he much preferred, and no matter how many trees came down the parks people would certainly replace them by planting more. His partner said she didn’t like the increasing development in the local area but the tree felling didn’t bother her at all, and in any case it wasn’t a major concern for them because they would be moving from the area. My response to this didn’t go down well.

I believe we should all engage in our local area while we are living there – otherwise almost anything goes…. and usually, quite literally, it does. I have to admit that this makes me think about what people rely want – maybe some just want different things than I do, or perhaps they don’t see the subject as important, and if this is the case, there can be little doubt that they are wrong. I accept that sometimes it is necessary to remove a tree that is in the wrong place, especially if it presents an obvious danger. Invasive species sometimes need dealing with and species that have been lost may need reintroducing: salmon berry has been re-established in some places here and its return is very welcome, but for the most part, a natural woodland that is re-generating successfully should be left alone – nature knows far better than we do where a tree should grow.

Some woodlands become waterlogged through fall and winter and there is no clear way of knowing which trees will be torn out at the roots.

A tree that comes down in the interior may create a useful glade and increase plant diversity, but along the borders such an event can be destabilising and the incidence of ‘tearing out’ will usually increase in exposed locations; and a small woodland suffers from having a more exposed perimeter in relation to its area that a large forest.

I was sorry to see this old conifer come down. At the cut point it had a circumference of 14 feet and was 4 feet in diameter. About a hundred years old, the rot had set in further up the trunk,as indicated by bracket fungi, but a little rot shouldn't immediately result in a death sentence - the tree was still providing a source of nourishment for a great many species.

The same tree a month before it was felled was beautiful. Old trees with little or no top are unlikely to fall until they are very rotten and this one hadn't reached that stage. Sadly, the old trunk had been viewed with a garden rather than a forest mentality.

A recent addition to the forest has been the introduction of information posts and these  really do need felling. There is plenty enough information that we have to absorb outside of the park; in urban environments this kind of thing is everywhere and we should be able to come to a woodland haven to get away from all of that. If there is a need to have an information board, then it should be at the entrance to the woodland walk with interior areas left free of clutter, which otherwise ruin both views and photographic opportunities.

These signs do have their uses in cold weather - I know exactly how cold it is at the point when the snow begins to slide off the top board - to reveal rhyming details for a woodland dweller, presumably with the intention of engaging children.
These signs do have their uses in winter – I know exactly how cold it is at the point when the snow begins to slide off the top board, but my preference is the snowy cover – beneath there is a picture of a woodland dweller with an accompanying description in rhyme, presumably to engage the minds of children. Sadly, the poetry leaves me feeling even colder than the snow.

Ironically the most recent information post to go up beside the path provides a description for pileated woodpecker, which is odd, because every tree along the way with even a little rot has been felled, leaving very few places for woodpeckers to feed or nest where they might easily be seen.

I didn't get the opportunity to observe pileted woodpeckers so easily before coming to Canada - these birds are a joy to observe as they hammer away at an old tree trunk, and there is a certain sadness in that I shall no longer be able to watch them so regularly in the local area.

If it doesn't work out, I guess I'll just have to rely upon memories of my English childhood when I would sit and watch Woody Woodpecker cartoons on T.V. and dream one day of coming to North America to see the real thing.

We need to be safe, but not ridiculously so. Cutting down a tree in the adjoining Fleetwood Park Garden is an altogether different consideration – a carefully laid out garden is a discipline that doesn’t pretend to emulate the wild. The woodland on the other hand isn’t just a place for joggers and people emptying their dogs, it also has a role to play in conserving nature, much to the delight of those who care about such things. When people lack transport or the necessary mobility to travel so extensively, natural parks in urban localities become an increasingly important amenity, especially as the natural world is pushed increasingly further away by development.  There is very little woodland left in most suburban areas and the last thing we need is overzealous tree cutting. A favourite mantra is that it is happening everywhere now, but that isn’t a good enough excuse to ignore the problem, we need to react.  So, when you see too much tree felling in your area – make a fuss; and remember… take a picture – and who knows, maybe one day this might help to save the Planet.

The Plight of the Eagle – Urban Development.

After I wrote my first blog my daughter told me that I would need to write new ones quite regularly, because, as Punch said to Judy, ‘That’s the way to do it …’ This was quite a shock, although it has nothing to do with Punch sounding loud and shrill, and everything to do with ‘quite regularly’ sounding like a job. The blog started over concerns about an environmental issue and rather stupidly I hadn’t thought much beyond that. There are a couple of other concerns as well, and my friend Colin put his finger on one of them straight away, ‘the trouble with you,’ he said, ‘is that you usually say what other people are just thinking’… and in these politically correct times that could be a problem. Assuming that I do have readers, I will eventually upset them all and end up writing for myself, which begins to sound less like writing and more like therapy; and that brings me to my second problem… I’m not sure I’m bothered.

The Canadian fish eagle – sometimes known as the bald eagle – is quite something. When living in England I lived at the wrong end of the U.K. to see Britain’s, or more properly, Scotland’s national equivalent, the golden eagle. You’re best chance of seeing one of these would be to travel to the Western Highlands and get well organised for a photo opportunity. There are around 440 pairs nesting in the U.K. and I have only viewed single birds in flight, none of them near a nest.

Then, I moved with my family to New Zealand where you can forget about seeing eagles altogether; most of the interesting native avians are either extinct or moving down that rocky road to oblivion; although New Zealand has been a land of birds and so it is no surprise to discover that there was once an eagle in the mix – Haasts’s eagle, the most impressive tick for a birder that can be imagined – and I don’t mean that in the parasitic sense, although the bird may well have had species specific ticks that disappeared when the bird did. The great thing about this eagles is that it was the largest predatory bird ever known to exist. Sadly, Haast’s eagle disappeared about the same time as nine species of flightless moa which were all hunted to extinction by Maori around A.D.1400. With their prey gone, the eagles quickly climbed the stairs to stuffed, or more precisely, to ossification. Imagine if you can, 35 lbs (15 kg) of bird in flight, the estimated upper limits for a large female… extraordinary, and I missed the picture by around 600 years, but it wasn’t personal, so did everybody else. And right now you’re probably Googling the bird’s name to see if I’m fibbing.

Over the years I’ve made many trips to the United States but it was a long time before I saw my first bald eagle. To avoid confusion I use the bird’s American name although I don’t feel obliged to do so, vultures are bald but eagles for the most part are not. In the middle ages ‘bald’ would refer to a patch on a stock animal, but an entire bird’s head is something else. I love America, but let’s face, it, Americans are none to precise with words – in reality a bathroom isn’t a lavatory, and if an herbivore is an herbivore, how can an herb be an ‘erb’ What’s that about? And ‘The World Series’???… Let’s not go there.

Sorry I digress, we all know what a bald eagle is, but they were certainly less frequently seen during the 1980s than they are today in every state in America, but the bird did manage to cling on and breed in a few of them, including Florida which is where I had my first encounter with this wonderful eagle in the Everglades. Startled from its resting place in a tree, the poor creature almost fell on top of me as I quickly tried for a picture with the 200mm lens that was attached to the sharper end of my camera. Unfortunately the eagle was far too close for a long lens and by the time its feathers came into focus the bird was moving away and quickly hidden by foliage. If I had failed so completely and missed the photo in almost any other state my story might have been doubted, but in Florida seeing a bald eagle was very believable and nobody had reason to question it. I had nevertheless missed the shot – photographers see things differently, they freeze away packets of light while others have life experiences; they store away little capsules of time to be viewed at a later date, although any picture that has been recorded successfully is soon forgotten. It is the ones that get away that are remembered forever, or more correctly… remembered until you die.  A photograph on the other hand need not suffer oblivion, but it is as well to consider that there are as many bad photographs in the world as bad memories; and by that I mean memories are unreliable, while photos – if we exclude photoshop – pin down a certain kind of truth… I know, we could argue that one all day.

In British Columbia, where I now live, people can be complacent about their Canadian fish eagles, because the birds are so frequently seen, but that could easily change as habitats become degraded or destroyed. In the United States the birds have survived in part because they have a wide distribution. Early in the 20th Century they were hunted mercilessly because of the fear that as predators they might eat young stock animals, in particular lambs. Nobody at the time had heard of trophic cascade and many still haven’t. The term describes the important role that top predators play in shaping ecosystems or even landscapes as they work the top end of the food chain and the results tumble down through the system. Only recently has this process become more clearly understood and eagles are certainly up there amongst the top carnivores when it comes to ripping at the tapestry of existence.

Having survived an initial assault with guns the eagles would plummet in numbers again around the middle of the 20th Century with the widespread use of the pesticide D.D.T. which would accumulate in the bodies of many predatory birds and cause eggs to suffer from a thinning of their shells which were easily broken before the embryos inside had a chance to develop fully. Many raptors would totter precariously on the edge of existence until D.D.T. was banned in 1972; it takes about 15 years for the pesticide to break down in the natural environment, and so it was a while before fortunes changed and eagle numbers began to climb.

In the United States the bald eagle appears on just about everything from national seals to custom paint jobs on Harley Davidson motorcycles – a perfect example of the power of visual imagery, but you have to wonder how the bird might have faired had it not been politically expedient to save it. More generic eagles with less literal forms show up on the coats of arms of more than twenty five countries, but there has never been a closer association with a single bird species than the United States has with the bald eagle, except perhaps the relationship that New Zealanders have with their namesake the kiwi.

In British Columbia and Alaska, this fish eagle might be described as common, which is perhaps why it is taken for granted. During the salmon run, the fish move some distance inland along the rivers of the North West coast of North America to spawn and the eagles, congregating in numbers, rely heavily upon them for food. When the salmon stop running the birds behaviour changes and in late winter an early spring they move off to their traditional nesting sites, many of which are now threatened by development, especially when bordering urban areas, which in lower mainland B.C. is becoming increasingly difficult to avoid. Urban eagles can cope with some human disturbance, but increasingly there are fewer places for them to hunt while they are tied to the nest feeding young.

I have been fortunate to record eaglet rearing activity at my local nest over the last few years, which will attest to their presence should they finally run out of prey and are forced to move away; certainly things appear to be moving in that direction. In 2012 two eaglets fledged successfully on the local nest; last year there was only one eaglet and this year one again, after the adults were forced to rebuild when the old nest fell during a winter storm.

Under exceptional circumstances a pair of Bald, or Canadian fish eagles  might rear four youngsters; three is hopeful, but two is more usual, or rather the laying of two eggs is more usual. The rearing of only one offspring is common enough, but doing so season after season suggest a lack of available prey – perhaps they could do better under more favourable circumstances. At least two other nests in the area also managed only one youngster during the 2014 season.

Nobody it seems can remember a time when there weren’t eagles nesting here; people have become so used to seeing them and may be unaware that the birds could be lost to the urban developments spreading across the surrounding woods and farmland. Close to the park’s borders this process has been startlingly rapid over the last couple of years, which is unsettling and casts doubts over the longterm viability of the nest and I really hope the adults manage the increasing distances they will need to travel to hunt down prey. Whatever happens, it has been a privilege to have spent time watching and photographing these wonderful birds.

If planning departments are prepared to give over land designated for agriculture, along with natural areas in and around urban locations, then many native plants and animals will inevitably disappear from the landscape and our lives will be the poorer for it. Only a few people will gain financially from intensive house building, whilst the majority will see little benefit. Living closer to nature has been demonstrated to be of great benefit to our health and this is increasingly denied to a great many people. Essentially, we will move past the point where there are teachable class sizes at local schools, or reasonable waiting times in the emergency rooms of hospitals. It is of no great benefit to the majority to push urban density to the levels we expect to find in cities, but few of us are allowed any part in the decision making. As a neighbour recently pointed out, ‘When it comes to development, money talks and b/s walks.’ And that pretty much sums it up. Urban development programmes should not be ruled by a minority who are turning a buck at the expense of the majority, and above all else financial gain should not be allowed to push intelligent urban planning into second place.
