Life and other sharp things

It wasn't so long ago that we were celebrating the elimination of bramble from much of our garden and recovering from clambering around the steeper parts where the stems seemed to hide most successfully. Realistically 'elimination' was never going to be the correct word since, much like the cockroach which was one of the few creatures to survive the Late Permian Extinction Event, bramble is a tough plant to kill. So now that we are firmly into summer and everything in the garden is growing at full speed it is inevitable that the tough roots which still lie beneath the soil are sprouting new shoots wherever they can. And it is here we come across one of the plant's cleverest strategies. It likes to hide its new shoots within the stems of another shrub so that it becomes visible only when the shoots have acquired significant strength and toughness and are pretty much indestructible. But this is only part of it. The clever bramble will select a host plant in which to hide which has its own defensive strategies, be they sharp thorns or stinging leaves. From a human perspective this can be seen as a cunning plan on behalf of the bramble since most attempts to remove the plant will involve pain of one sort or another, enough to discourage most people. Nettles are one example of a favoured bramble companion but in our garden we also have gorse, holly, wild roses and strawberries and also blackthorn, the latter having long dangerously sharp thorns hidden amongst its innocent looking foliage, spikes that will penetrate even the toughest glove. In fact we hadn't realised just how hazardous our garden was until we started searching out those spiky little bramble shoots and we now live permanently with the consequential scratches on our arms and legs.

Having got all that out of the way it is now time for a short pond update.

So we'll start with The Mud, a technical term for material recovered from a discreet raid on the pond in the public wildlife area of our local castle. This pond is quite natural (indeed it may well have been there when Robert the Bruce was rebuilding the castle back in 1325) and the small container of mud that we liberated brought us a random collection of tangled roots which will almost certainly add to the diversity of vegetation living in and around our pond.

The mud is now spread out along the margin in such a way that those roots can extend into the water whilst keeping a footing on the bank. At first it simply looked like, well, just mud, but then gradually on my daily progress checkups I began to notice thin strands extending out into the pond beneath the water, roots seeking out nutrients to feed something living within the mud and then eventually tiny shoots rising from the mud itself. We have no clues as to what might be growing and nor do we care. It is life, in all its complexity, which is all that matters.

At this point our pond is less than six months old, a hole dug into sloping ground with a plastic liner and an overflow pipe to keep the water at a constant level. Two separate raids on the castle wildlife area have brought us a small sample of plant life, an insect menagerie (although most of this may have found its own way there, we assume by air), a small collection of tadpoles and a newt called Nigel. There are now countless water beetles and pond skaters, damselflies engaged in egg laying but sadly the tadpoles are gone and we think we now know the reason for this. Hidden amongst the imported weeds was a large nymph which has gone on to become the biggest dragonfly we have ever seen - the size of a small bird. The nymph's exoskeleton was left behind, floating about on the surface, a reminder of an early life spent gorging on amphibians who had nowhere to escape to. The adult dragonfly pays us occasional visits so maybe he/she has designs on making this a permanent home. Time will tell.

The pond will develop, becoming more natural looking as the mud and the surrounding vegetation matures to hide the exposed edges and we hope that by next year this will attract other amphibians who might just happen to be passing by and who might fancy spawning there. Perhaps even Nigel will return.
