Just lately I have made a few visits to an Adder (Vipera
berus) hibernation site I have known about for many years. They are a breeding population and I have
kept a few occasional, but not particularly scientific records in this time. Mainly about when they first
emerge from hibernation, population numbers and whether I spot any of the young. In many ways it has become a part of my spring routine.
The first trip was at the beginning of March, but conditions
for seeing them was borderline in that it was cloudy and cold, so it was hardly
a surprise when I did not spot any. On
a second trip it was sunny but still cool and I only spotted one, which was
highly aggressive and began hissing and striking before I got anywhere
near. It is possible to identify
individuals by their head markings, but even so I knew from his reaction this
was Mr Grumpy (AKA number 2). I grabbed
a couple of shots using distraction to avoid getting bitten and left him in peace.
Number 2 (Mr Grumpy) basking with body flattened to absorb the maximum heat from the spring sunshine |
A couple of weeks later with the weather now much warmer I
headed back. No Mr Grumpy this time,
but instead Number 4 who is a rather more passive character, who along a smaller
snake I could not identify were happily basking in the sunshine. I was a bit too impatient in getting a pic and they soon
disappeared. I knew if I waited they would soon reappear and within a few minutes number 4, tongue flicking to
taste the air, slowly emerged from his hiding place.
Personalities aside, close up it is possible to tell individual apart by their head markings |
He knew I was there, but by keeping myself still he seemed
happy to emerge fully and then flatten his body to get the maximum heat from
the sun. I watched him for perhaps 15
minutes or so and then suddenly, without any apparent reason, he became tense and with
tongue flicking coiled up in the familiar posture they adopt when they feel
threatened. Looking around I could see
nothing, but a few seconds later the strong smell of burning heather reached us.
Now clearly it could have a bird, or perhaps some vibration
from the numerous helicopters that were flying around at the time, but it did
get me thinking about what the effect would be if this patch of heather was
burned when they were basking. Would
they simply head below ground and avoid the heat, and if so would they
suffocate from the smoke instead? What
if they were too far from their hibernation hole to get out of the way?
I know heather burning is highly controversial and I have
listened to, and read up on the various sides of the argument relating to
pollution, vegetation damage, habitat loss and the effect on wildlife. That said I had not paid a great deal of
attention to the impact of such activities on reptiles such as snakes and it
was with thoughts like this rattling around in my head that I headed across to
the far hillside to see the burning up close.
I never know how people will react to me taking pics,
especially if they feel I may be there to present them in a bad light, which I
am not, I simply want to record what I see.
So far I have not had any issues and have had several friendly
conversations with various estate gamekeepers.
So much so that despite the fact I don't support any activities that
kill animals as a form of entertainment, I do try to take a balanced view and
avoid tarring all shooting estates with the same brush.
Either way it's not an easy thing to do when I see the level
of persecution of birds of prey, along with other predators such as stoats and
of course none predators such as the mountain hare, I can tell you.
Arriving at the fire, the closest gamekeeper who was setting
light to the heather gave me a friendly nod and hello so I grabbed a few shots.
This guy did not seem bothered by my presence either. |
After a few minutes a bloke with a soot covered face turned up on another tractor and asked me what I was doing taking pictures as the lads might not
want me too. At this point it's
probably not worth going into much detail, other than to say he did not want me
taking pics and wanted to know where I was from and what I would be doing with
the pics.
Despite the fact I showed him the shots I had taken and that
they did not show any faces he was still very unhappy about it. In the end I couldn't be bothered to argue,
and having got a few shots anyway headed off in the direction I had come
from.
On the way back I discovered some remnants of what these
moors should really be like in the form of some large old tree stumps that had
eroded out of the peat. How long ago
these trees last watched over this landscape I don't know. It could I suppose be as recent as a few hundred years ago, but then again preserved in the peat we
could be talking thousands of years. Either way you can bet humans had a hand in it.
We often talk about re-wilding the landscape and to do so here would mean the return of the trees. |
There are lots of trees like this on the moor. The altitude here is around 1,200 ft |
Despite my experience today this is not meant to be an anti
grouse shooting article and as I said I try to take a balanced view, because
lets face it, wind turbines in upland areas also destroy vegetation and peat
habitat with their concrete bases, miles of roads and other infrastructure such
as pylons and substations. You can also
add a large number of bird fatalities caused by cables and blade strikes to
this as well. Not to mention the visual
intrusion and the pollution created by making them.
With regard to heather burning, I don't have any answers, but considering that adders are active at this early stage in the year and given I do actually have records and images of them
captured as early as the 24th February,
the potential burning season of between ***1st October to 15th April (see edit below), does seem
far too long as far as adders go.
All in all, today was a day that really made me think about
our impact on the landscape and its wildlife, but most of all it did make me
wonder just where will it end?
