Having driven the road between Aviemore and Perth so many
times over the past 10 years, I could not help notice, during this latest trip,
the number of Mountain, Blue/White Hare’s lying dead on the road.
The above reminded me of stories told to me by my father and
the older Ghillies at Knockando, stories about huge numbers of Hares present in
the 50s and 60s, before, it would seem, almost disappearing altogether, their
population shrinking to near extinction by the end of the 1970s. Much the same
could be said of the Brown Hare, very common and present in huge numbers at the
same time before suffering, it would seem, the same fate as their white cousins
and all around the same time. So what happened? How did something present in
such huge numbers go from being culled in huge numbers each year, to near
extinction? And, what has changed to see them make a recovery?
As someone who has grown up in the countryside, watched
those changes come about, I have always been interested in such questions and
the possible and probable answers.
My first and only experience of shooting/culling Brown Hares
was in 1977 when, as a 14 year old, I accompanied my father on an organised
shoot early in the spring. Two lines of guns, one walking, one standing, would
drive those toward one another over ploughed fields, shooting as many as
possible. This, I have to say, was also my first experience of feeling sadness for
my quarry whilst shooting; the reason being, the noise made by those wounded
Hares, as a soft hearted 14 years old, the cries [ like a child], was just too
much, and although I carried on shooting all my life, I never did shot hares
again. I remember we shot 38 hares that day, a number many of those older
people shooting that day could believe was so low. Their numbers, by this time,
were already in serious and many said, terminal decline. So what has caused
this comeback?
The answer to this could be fairly complex, or, by the same
token, fairly simple, it really depends on how your head works, or possibly
your agenda. To be very simple – We, or those organising the culling of those
animals, failed to recognise the speed of the decline, shooting them until not
enough remained to repopulate, during a time of naturally decreasing numbers
due to long term weather/environmental change, something very natural, but
unfortunately taking place over a period of more than one lifetime. To all
intent and purpose, this sentence answers the question! However, if you want to
be more complex about it all, you could also ask, why to this question too? Although
99% of the answer is obvious, there are always those who seek, or make a living
out of, seeking 100!
No matter what we are managing there are simple ways and
more complex ways of doing this. Looking at this in a simple way – If we are
managing Grouse, a “wild” bird that cannot be bred, then there are two
important things we can influence to help them, namely – Habitat and Predators.
Simplistically, if you have too much of one and not enough of the other, i.e.
if those are not properly managed, then, even if environmental conditions are naturally
suitable for the birds during this period, you will not have a sufficient
population to harvest. Period! The population of anything totally wild will
always fluctuate due to those factors above. Everyone who has a good Grouse
moor knows exactly what’s required to manage it properly and that this does not
happen naturally by itself!
Pheasants and Partridges on the other hand are very
different, in that both can be bred and as such their population controlled by
us, man, the world’s No 1 predator!
So, managing something wild over something that can be bred requires
very different strategies. The brown and white hare are good examples of this.
Because they are totally wild, the Brown and White Hare population will fluctuate
naturally, their population will grow and shrink depending largely on man and
how he manages their Habitat and potential Predators. Although a by-product,
indirectly and through change in farming practice in the 1940s [more intensive arable
farming, ploughed fields over the winter providing them with cover and good
food supply in the spring] perfect habitat was created for the brown hare.
Perfect that was, until their increasing numbers begun to be noticed by man who
did not relish the fact they were eating his crops and damaging their trees;
two simple things which ultimately led to their demise. Of course there will be
environmental factors involved too, but those are things we have no control
over either in the short, medium or long term and in actual fact have only a
small part to play in the overall demise of the Brown Hare in the late 1970s. The
fact of the matter is, much like the wild Atlantic salmon, they were culled to
almost extinction at a time when naturally the chances of recovery were slim.
So why after 40 years has the Brown and White hare begun to
make a slight, but never the less, visible recovery? The answer is again fairly
easy, we are not now culling them, and have not done for some time. Add to this,
more favourable environmental conditions and they have a chance. Compared to
those days of mass culling their number is still small, however, given
proper protection I’m sure they will
continue to recover as, other than man, they have very few large predators.
Just as long as environmental factors remain favourable the recovery should
continue.
Can we use the same analogy when looking at the Atlantic salmon?
Well, my feeling is yes and no. Yes, and for similar reasons as above [mass
culling and failing to understand the decline], the population is only a fraction
of what it once was! Looking at the above, because they are 100% wild and now cannot
be bred, then our only hope of managing them is to deal with Habitat and Predators.
Some rivers have seen serious loss of habitat whilst others very little. But
one common denominator is predators. To use the above as an example, what we
now have with the protection of Seals, Cormorants, Goosanders, Mergansers
Otters and every other predator, leaves the salmon with no chance of recovery, it
would be like having a Grouse Moor with a dozen fox dens and a dozen pairs of
Hen Harriers, no chance at all, well, certainly not in the short term.
The problem and answer is there and obvious but I’m afraid
people are overly busy creating a side show, leading those away from the real
issues and tackling this obvious decline head on. There are two choices –
- If we are to continue managing salmon as a “wild”
animal then. Like the Grouse, we simply must manage their natural predators. Period!
- If not, then we must farm enough to feed those
predators [Bad, but only other option].
There are no other options. Can anyone imagine managing a
Grouse Moor purely by creating the perfect habitat and not killing predators? I
think not, lots of work for no return! Wild salmon are exactly the same and
those promoting habitat improvements only as some sort of saving grace to our wild
salmon know this more than most!! To some this may seem a step in the right
direction, but in actual fact, on its own, just like on the grouse moor, or like
we saw with the brown hare, the decline will continue until their killing by predators is stopped.
