Some days will always be slow ones. There will be those days where a long week will catch up with you, and instead of heading out at 5 am, you will put your alarm on snooze, get up at 6:30, and have a decent breakfast, complete with a cappuccino. Driven as one might want to be to get out on the water, sometimes fishing days will turn out that way. The rigors of a business week will catch up with you, and your body will rebel and tell you to “chill”.
On Sunday, I obeyed. Egg, bacon, beans, toast, ended off with a good coffee and a resigned but satisfied sigh. The river would have to wait.
When we did get up to the Umgeni, it was off colour. We paused at the bridge where the tar road ends and inspected it. Unlike the slate grey of a mountain stream in spate, we got cheap weak instant coffee colour. As always, there was hope that further up it would be better.
Arriving on the farm we met Russell. “It was crystal clean yesterday” he said. There had been a storm. He didn’t get it, It happened up there. He gesticulated in the direction of the source.
We went down to the river anyway. We crawled under the electric fence and went down to the water’s edge. It was still cheap coffee coloured. Damn!
I always peer into dirty water, normally along a protruding stick or log, to try to get a sense of how far into the water I can see, and therefore what the visibility will be for the trout. This time the dark shades of a wet branch disappeared within a few centimetres. Not good. Often the Umgeni appears a little ginger beer like, but this was nothing like that. I always wonder how much muddy water a Brown Trout can tolerate through its gills in a season. There must be a red line somewhere.
We strolled down the river, looking into each pool as though we expected, against all odds, to suddenly find a clean one.
I pointed out the log jams of wattles, and explained how these and other alien trees were the major contributors to the water colour we were seeing. Not only do wattles (Acacia mearnsii) contribute tannins, which give the Umgeni its yellowy brown hue on the best days (see What makes rivers different colours), but on the worst ones like today, it is the clearfells and Allelopathy that give rise to erosion. Years of apathy have lead to widespread patches of wattle, and they are especially prevalent on the farms of absentee landlords, and in road reserves. They also predominate on farms where licensed commercial timber is grown, but where there has been scant effort to contain plantations within the approved plantation blocks. The farm opposite us that morning is one managed by a corporate poultry concern. Their lack of veld burning and the absence of cattle to devour small wattles has lead to a wasteland of weeds and increaser species (the precursors to afforestation which are associated with poor basal cover).
We walked back to the car, and drove up river, stopping at another spot higher up.
I pointed out a recent clear-fell on the hillside in the distance. The commercial timber plantation there had been felled. It is a very steep slope, and it could be argued that no timber should ever have been allowed to be planted there. But the deed is done, and now we should be looking at how to minimize the damage. When last I was up there in the clear-fell last year, I noticed that the timber trash had been laid in windrows lying straight up and down the hill. An opportunity to use that trash as a soil holding device, by laying it along the contours, had been missed. I shudder to think how many tons of topsoil this caused to wash into the Umgeni river!
The section of river we were looking at there within sight of the clear-fell was dirty too. No surprises there. The banks at that point are planted to pasture. The pasture land extends too close to the river bank, if one is to follow the law to the letter, but one has to be pragmatic about these things. The cows grazing in the field near us have devoured any small wattles. The ground is also secured by a mass of grass roots that bind it all together, and there is no sign of erosion on this well farmed commercial enterprise.
Driving further up the river we passed onto the tenement above. While it is now owned by the same farmer, its history is different. Maybe no cattle were around to eat the emerging wattles many years ago. Maybe a fenceline kept the cows from the river bank, which on the face of it is a good thing. I do know that this piece of land was not owned by a man whose elderly father was a fly-fisherman. On the farm below, where we had just been, this was the case. Derek used to run a tractor down near the river with a mower, so that his ageing dad would be able to fish it in the late summer without undue effort. Twenty years later, it shows! The farm below is relatively clear of wattle. The one we were looking at now has a ribbon of big wattles running up the river banks. They are big trees now. In my estimation the cost to remove them would run to about….let’s see: A conservative estimate: R500,000 ($50,000). That would be to remove them properly: cut, pull from the river, stack, burn, and do some follow up management. On second thoughts, my figure is way too low, and that is just for a few kms of river. There are many more kms above this farm with the same problem.
My mood turned. I became dejected. It was not because I was not getting to fish on Sunday. Sure, that was a pity, but it was bigger than that. It was about our apparent collective apathy in handling this conservation problem. The same type of apathy that had me ignore my 5 am alarm clock, is the very thing that is at play here.
In recent years I have witnessed wattle infestation high up berg rivers, and in other places, where no one has noticed, and no one is doing anything about it. In many places those trees are already large and the job of removing them seems insurmountable. In other places the trees are still small, but no one has noticed. The passage of time alone will surely multiply the extent of the problem to something beyond our grasp.
On the way out I witnessed freshly felled wattles along side streams, where a WWF initiative is underway. At other spots I saw an absolute mess where a contractor appears to have pillaged the useful timber and done a runner with the money, without finishing the tidy up job he was employed to do. It was an emotional see-saw in which I tried desperately to interpret the mixed results as an overall win. I am unsure if we are going backwards or forwards in this river valley at present.
We stopped for a beer and a pizza at il-Postino to cheer us up.
It worked. It was a relaxed Sunday, and it was pleasant to sit on the porch of what was our local trading store in my childhood. From there we pulled in at Steam Punk, a simply superb coffee shop in the most obscure of places, where I had a “Coppucino” ( a cappuccino made the Syrian way, with Cardamom, just the way I like it).
It is easy to just enjoy the beer and the coffee and forget about it all.
