I’ve been away for a while with work, so I’m late catching up with my correspondence.  Sheila, Rick and Mrs B – thank you for your comments and apologies for being so slow in replying.  I always enjoy hearing about other people’s experiences, so please keep them coming.

Somewhat accidentally, I now have an international perspective to the blog.  Steve has been kind enough to send pictures from the New York/New Jersey border.  He found the tracks after sighting a fox near his house.

Mystery Snow Tracks

The problem is, they don’t look like fox tracks to me, at least not the familiar British fox tracks.   Fox tracks are small and neat and diamond-shaped.  These are hand-shaped.

I’m not an expert on North American wildlife, but the closest match I can find in the guidebooks is Raccoon tracks.  Does this make sense?  Do you get Raccoons in northern New Jersey?  Do they walk around people’s houses?

This is just my best guess.  If anyone has any other ideas, please do let me know.

For the past week the country has been gripped in a little ice age.  An area of high pressure has settled over Britain, trapping cold air and snow, blocking out the prevailing warm south-westerly winds.  Temperatures as low as -20c have been recorded (my family in Cheshire experienced -14c) coupled with up to a foot of snow.  Predictably, the whole country has ground to a frozen halt.

Personally, the only problem I have with the snow is that I haven’t had enough time to go out and play in it.  Unlike this time last year (see Fieldnotes: 4th-10th January 2009), I’m limited by work and family commitments.  It’s one thing to go out and freeze myself following badger tracks in the snow.  It’s another thing entirely to do it while carrying a five month old baby!  Back in the old days I’d have packed up a tent and sleeping bag and headed out into the woods, just for the challenge of it.  Can’t really justify that now.

Nevertheless, today I drew upon Mid-Bedfordshire’s tradition of polar exploration (there is one, honestly) and went out into the snow to see what is happening.

Here’s some new tracks to have a look at.  These are squirrel tracks.  I watched the squirrel as it bobbed around in our garden and then went out to look at the tracks.  The pattern is similar to that of a rabbit – the same bounding gait – but smaller.

I walked on up to the pasture field to look for evidence of the badgers.  The snow last year was a priceless help in deepening my understanding of badger habits and how the local territories interacted.  This year the picture was much more confused.  There was almost a weeks worth of tracks, of animals and humans, and recent falls of snow have complicated matters still further.  Nevertheless, it was possible to trace the movements of individual badgers.  Clearly visible were the patches where they had dug through the snow into the soil.  I couldn’t see any dung, so I assume it was for food.  Badgers don’t hibernate, but they do slow down.  It’s a useful thing to know that badgers will still come out and forage, even in these extreme weather conditions.

Inside the wood there was more evidence of badger activity.  I didn’t get to visit the sett itself (like I said, there is a limit to how far I’ll take my daughter in these conditions – sturdy girl though she is) but I did add a few more snippets to my badger map of the area.  The wood is criss-crossed by paths, but it is difficult to know for sure that they are badger paths. Very often the only tracks you’ll find on them are for deer.  Today, however, there were clear badger tracks, showing that these are indeed badger paths.  I’ve tried to follow them in the past, as I suspect they lead to the almost mythical ‘third sett’ in the area, but I’ve always lost the paths among the trees.  If the snow persists I’ll have the perfect chance to follow them to their source.

The snow told other stories too.  There were plenty of fox tracks in the field.  They all converged on a post where the foxes had obviously scent-marked.  Just like dogs, I guess.  It’s all part of the territory marking.  Foxes will tend to leave dung in exposed places such as tufts of grass for the same reason.  It’s a nice little insight into fox behaviour.

Lastly, here’s a bit of a mystery.  These tracks were in the middle of the field.  It’s a bounding gait again, with the tracks in groups of four like a rabbit or squirrel, but only a few centimetres across.  The individual prints were not visible in the snow, but the gait can be more revealing.  Something the size of a mouse would surely have burrowed under the snow, not bounded over it.  I’ll need to look this one up, but in the meantime any ideas are welcome.

Snowy landscape in BedfordshireLast year I had the opportunity to visit Toronto, in Canada, on a fleeting business trip.  I must say, it’s a very nice city and the people were wonderful.  But one thing puzzled me.  The whole downtown area was connected by miles of subways.  It was possible to walk from one side of the city to other, to shop, to eat, to sit and drink coffee – all underground. It’s a strange subterranean world.  When I commented on this architectural oddity to a local resident she just gave me a knowing look. “When you have six feet of snow for six months of the year, why would you want to walk outside?”

This seems to me to be a very sensible way of dealing with a harsh climate. Unfortunately in Britain we have neither the common sense nor the fortitude of the people of Toronto.  The South East of England received 10-20cm of snow this week and, predictably, everything ground to a halt.  I don’t know whether all the stressed-out workers are looking for any excuse to take a day off or whether we’ve lost any sort of self-reliance,  but either way it’s a pretty poor show.

And me? I love snow.  I like nothing better than getting out and exploring after a decent fall of snow, and since I became interested in tracking I like it even more.  Tracks in the snow offer a real window into what’s been happening, what animals have been out and what they have been doing.  Naturalists have used all sorts of techniques to record the movements of wild animals, from radio transmitters to long pieces of string.  A couple of inches of snow will do the same job in a much more interesting way.

On Saturday I wrapped Scarlett in her warmest clothes and headed out.  I couldn’t take her too far, but we had a nice walk around the fields.  Long enough for me to show her the common tracks in the area.

Here’s the most common – rabbit tracks.  Every now and then I come across someone who says they’ve found strange and enormous paw prints, but what they’ve seen is not the marks of giant toes but the tracks of all four feet of a rabbit.

Rabbit tracks in snowRabbit tracks

Which way was the rabbit travelling?  That’s right – left to right.

There seemed to be a lot of fox tracks around.  We live in an area where there is a lot of rearing (and shooting) of game birds, so foxes are not exactly popular.  We used to see far more of them when we lived in London.

Fox tracks are small, neat and diamond-shaped, with four toes and a heel pad.  Notice how the small heel pad forms a straight line at the back of the track, almost like a straight bar.

Fox track in snow

It can be easy to confuse fox tracks with those of dogs.  Most dog tracks are broader than fox’s, with the toes more widely-spread.  The heel pad is usually larger too.

Dog track in snow

Dog track - note the wider shape and the spread of the toes

However, dogs come in all shapes and sizes.  Some dogs are bigger than others.  The tracks of small, terrier-like dogs can look very similar in shape to fox tracks.   The way to tell them apart is the spacing between the front and rear toes.  Look at the fox track again.  The front toes are forward of a line drawn across the ends of the rear toes.  In a dog, the front toes overlap with this line.

Fox track - key features

Fox track - front toes forward of rear ones

Another quick way of telling fox and dog tracks apart is to look at the trail – the series of tracks.  Fox trails always seem to be very purposeful.  Foxes seem to walk in a straight line, one track in front of another.  The tracks have a direct register, in other words the fox puts its hind feet into the tracks of its front feet.  To the novice, it can look as if the fox is walking on its hind feet like a human.

Dog tracks, on the other hand, don’t quite register, so you’ll get front and rear tracks close to each other but not quite overlapping.  Dogs don’t seem to have the same sense of purpose as foxes – dog tracks will often meander around as the dog wanders this way and that.  With a bit of practice you can tell dog tracks from fox tracks without having to look closely at the individual prints.

The temperature hasn’t risen much above freezing all weekend, so hopefully the snow will last for a while yet.  That suits me fine.  Tracking in snow is absolutely fascinating.  Put it this way, if I lived in Toronto I’d happily venture above ground to spend months tracking the local wildlife.

Things have been a little quiet around here since we’ve got the new addition to the family.  Scarlett and I have been out for a few walks already, but I’ll wait until she’s settled into more of a routine before I get back to any serious badgerology.  In the meantime, here’s a post from the vaults.

This is a short essay on setting up a track trap in my garden.  This is a simple and fun thing that anyone can do to try tracking in any small space.  The originally appeared as a discussion on the Tracking Group of the Woodlife Network, but if you’re not a member of the network (and it’s highly recommended to anyone interested in the subject) hen you may be interested in seeing it here.

I’m quite fond of hedgehogs, but we rarely get them around here. When I found some hedgehog poo in the garden in June this year I was quite pleased. It would be good to get a resident hedgehog around the place.

Hedgehog poo

I bought myself some hedgehog food to try and entice the urchin to stay, but the problem is that it might get eaten by birds (or by my cat – she does things like that). How would I know that the hedgehogs had been eating it and not some other animal?

Hedgehog food

I decided to set up a track trap – in other words I would place the food so that whatever eats it will have to leave their tracks. I’m going to make them work for their supper by leaving me tracks in return.  This is an established technique for unobtrusively identifying and monitoring animals.

First I took an 18″ square plastic tray. We use these trays in the greenhouse to put plants in.

18 inch tray

I added a 2″ deep layer of moist sand. I used silver sand from the garden centre because I’m lazy, but I could have just dug some sand or soil out of the ground. If you want really high definition you could use damp clay, but I was happy with sand. It’s cleaner too.

Add the sand

I smoothed the sand off with a piece of wood.

Smooth the sand

This will make sure that any tracks show up.

Nice and smooth

And finally I placed bowls of food and water in the centre of the tray.

Track trap baited with food and water

And there it was – a completed track trap. Any animal or bird that eats the food would leave its prints in the soft sand. The only drawback of using the tray is that it may prevent very small animals from reaching the food, but that suits me since the aim was to feed the hedgehogs.

The next morning I rushed out to see if there were any hedgehog tracks.  It was actually quite exciting – there was a real sense of anticipation.

The track trap had worked perfectly, but sadly there was no sign of a hedgehog.  The only tracks were from my own cat.

Cat tracks 1

Cat tracks 2

The fact that the cat tracks showed up so clearly did at least demonstrate that the trap was an effective way to identify the animal that had eaten the food.  I consoled myself with the fact that at least the cat hadn’t used it as a litter tray!

There was no sign of the hedgehog the next day either.  Nor the day after that.  In fact, after three weeks, the only tracks I found in the trap were from the cat, blackbirds, slugs and a squirrel.  No hedgehogs.

It seems that the hedgehog had left my garden.  Apparently, hedgehogs can walk for up to two miles in a single night, so it is quite possible that it was covering a large area.

Not discouraged, I continued to put the hedgehog food down.  Eventually, after two months, my patience was rewarded.  I finally got hedgehog tracks in my hedgehog track trap!

Hedgehog Track 2

OK, so it was a long wait to get tracks from what is, after all, quite a common animal.  But that’s not the point.  I set out to deliberately target a particular species based on its tracks, and in the end it worked.  The trap was fun to make, and it gave me the chance to collect and study animal tracks in the comfort of my own garden.  It’s a simple technique that anyone can use, and one that can be applied in the field too.

I haven’t had the chance to get out badger watching this week.  I’ve been continuing work on my shelves (and very nice they look too) and we had a dinner party last night, so the badgers have taken a bit of a back seat.

It was a bit of an effort to get out of bed at 6.15am on a Sunday morning, but worth it.  We had rain of biblical deluge proportions here yesterday so the ground is nice and soft – ideal for checking out tracks and seeing what’s been happening around the area.

The soft ground meant that I was able to follow the trail of the local badger for longer than ever before.  This time I stopped being lazy and did what I should have done ages ago – I measured the tracks.

The idea behind measuring the tracks is to see if I can recognise individuals by their footprints.  If you had a badger with a noticeable injury to its foot, or a strange walking pattern, then you could recognise it easily.  With a normal badger it is more difficult to tell their tracks apart.  My approach is to measure print size and stride and use these measurements to try to recognise individuals.

Measuring the stride length of a badger

Measuring the stride length of a badger

Of course, print size and stride length are not constant – they vary with ground conditions and terrain, as well as the gait and speed of the animal.  It is a maxim that a footprint is not a record of the animal’s foot.  It is a record of the interaction between the animal’s foot and the ground.  On soft ground the foot will sink in deeper and the print will be larger, plus the animal’s toes may splay out and increase the size further.  On harder ground the print will be smaller.  For this reason a single measurement would be an inaccurate guide to the identity of the animal.  A better approach must be to take a number of measurements and take an average.

In the photo below, the badger tracks are almost registered (rear foot on top of front foot) which shows the badger was walking at normal speed.  This helps to keep the measurements consistent, since I can look for this track pattern in the future and know the speed of the badger.

Measuring the width of badger tracks

Measuring the width of badger tracks

I took my width measurements across the four largest toes.  These are the most easily distinguishable part of a badger track so it’ll be easy to measure this again in the future.

For the record, I measured the width and stride length of seven consecutive prints today.  The average width was 5.2cm (front and rear feet the same) and the average stride length was 39.25cm.

This isn’t a huge sample by any means, but it should be a reasonable accurate baseline measurement for this individual badger.  I’ll take more measurements each time I go out, and see how consistent it is.  Over time I should be able to recognise this individual and also spot any different badgers in the area.

This may sound like a lot of effort to go to.  It probably is.  But then again, it is a way of using tracking to build up detailed and accurate information about the badgers in my area.

Badger tracking

Badger tracks

Badger tracks

You may recall that I dealt with a roadkill badger a couple of weeks ago.  I was concerned that the badger had been killed next to a field that forms part of my usual Sunday morning tracking/ birdwatching walk, and I hoped that the dead badger wasn’t the one that I had become accustomed to tracking.

Well, I went for my usual Sunday walk this morning, and I’m pleased to say that the badger is alive and well and still making tracks.

Tracking really is a fascinating activity.  I spent an hour totally absorbed by the animal tracks in a hundred yards of footpath up one single field.  Over the last 24 hours a badger, a fox, several Chinese Water Deer and a small herd of fallow deer had all walked up this path.  It was a tracker’s heaven!

We’ve had a combination of rain showers and sunshine recently, so the normally hard-packed clay in this field is soft in places, but still firm in others.  Many of the tracks showed up only as smudges in the fine silt on top of the clay.  In a strange way it is more satisfying to find and follow these faint images.

Here’s another set of badger tracks.  Note the claws on the front paw on the right.

Badger tracks 1

Here’s where the fox and badger walked side by side (actually, the fox was there first – on the next set of prints I found that the badger’s track overlay the fox’s)

Badger and fox tracks

The badger’s front paw print is on the top left, its rear paw on the bottom left and the fox on the right.

Who would have thought that a short stretch of path could prove so interesting – and so informative.  If you’ve never tried tracking then give it a go next time you’re out and about.  It really does add an extra dimension to your knowledge of the wildlife in your area.  And it’s great fun too!

Winter Oak

Winter Oak

On Monday it snowed.  We had about 4-6 inches of snow, but it was enough to paralyse the whole of the UK.  Everything ground to a halt – the roads jammed up or closed, the trains were cancelled, and even the London buses stopped running for the first time ever.

I woke up at 5.30am as usual, saw the snow and decided to work from home, which I’m luckily able to do.  But once again my thoughts were on tracking, with visions of following badger trails across the pristine fields of snow.  By 9.30 in the evening I’d got dressed up and slipped out into the freezing night.

You may think that I’m eccentric for going out in the middle of the night during the worst snow the UK has seen for 18 years.  You may find it difficult to understand my excitement and wonder why I didn’t sit by the fire in the warm like everyone else.

Let me explain.  I’ve been watching badgers for three years now, and I’ve got closer to them than most people ever do.  I’ve sat by their setts and watched them come out in the evening, and I’m starting to understand their behaviour.

But there’s a whole big part of the badgers’ life that I know very little about.  Every evening they leave the sett and spend the night foraging.  I’ve caught brief glimpses of them as they range about their territory, but the truth is that it’s still a mystery to me.

Tracking has helped me fill in some of the blanks.  An animal’s tracks are an enduring record of its movements, so they help you to piece together its activities.  As well as being a fascinating pastime in its own right, tracking adds to my overall picture of badger behaviour.

But if tracking is like reading a book, then it’s a book with only one or two legible words on each page and most of the pages missing.  You can only track in areas of soft ground, so most of the picture remains hidden.

But snow, now!  Snow gives you the chance to see the whole picture, if only for a night.   Imagine spending months and years trying to understand a book from a few isolated words, and then imagine having the chance to see the whole story, page after glorious page.  Given the chance, wouldn’t you want to get out there for a look?  Isn’t that worth a walk on a snowy night?

So – out into the cold night I went.  Actually, it wasn’t too bad.  Because of the snow it was light enough to see without a torch, and it was exhilarating to be out when the rest of the world was tucked up in bed.

When I got to the pasture field, it was everything I had hoped for.  There were tracks of rabbits, and a fox, and some people with a sledge; but there amongst them were the clear tracks of badgers, no more than an hour or two old.

Thinking about it afterwards, Monday night reflected my development as a tracker.  When I first started tracking, I was excited to find tracks and identify the animals that made them.  So it was on Monday, and I was delighted to find clear badger tracks in the snow.

Here’s a badger forepaw – note the claws, the big pad and the toes like peas in a pod:

Here’s a badger track as you often find them, showing the rear foot superimposed on the front one:

But recognising tracks is only the first part of learning to track.  The interesting thing is using the tracks to tell you about the behaviour of the animal.  I spent two hours in the field, following the tracks of four different badgers.  This was a priceless experience – for the first time I was able to get a real understanding of their movements.  I could see where they had dug into the snow for food:

Following the badger as it foraged

I could even see where they relieved themselves:

Badger urine (makes a change from pictures of dung!)

Mind you, with badgers nothing is simple.  This is just as likely to be scent marking as anything else (see my post on why badgers use paths for more details).

The next level of tracking is not just understanding the individual animals, but understanding how they interact with each other and with their environment.  I followed the tracks of each badger as they meandered across the field, but where the tracks crossed an interesting thing happened.  You could clearly see where the second badger had come across the tracks of the first – it would double back or walk in parallel for a short distance.  This happened on every occasion the tracks crossed, so the badgers were obviously aware of each other, presumably by scent, and checked out each others’ tracks.

Badger tracks interacting

It was absolutely fascinating to see how the different trails interacted.  At one point in the field the tracks of four different badgers converged.  One of these trails came out of the wood, went to this very spot, turned round and went back again.  This cannot be coincidence – this was obviously an illustration of some badger behaviour I don’t yet understand.

Four badger trails converging

Wandering around a snow-covered field in the middle of the night with a torch is probably not everyone’s idea of a good time, but I thoroughly enjoyed myself.  I learnt more about the foraging activities of my badgers than I have done in years.  I learnt about the routes they took and the way in which they interact.  By following the tracks I’ve revised my ideas about the size of their territory (bigger than I suspected) and the boundary markers they use.

Two hours went by quickly, and then it was time for bed.  While the rest of the country ground to a halt, I had a wonderful evening of tracking.  Like I always say, this sort of thing is out there for anyone willing to take a look.

Have a go at tracking a badger

This Sunday I found a lovely clear set of badger tracks from the field behind my house.  It seems this badger has a longer route than I thought, and it’s making me think about where its sett could be located.

If you want to have a go at tracking a badger, have a look at the photo below.  It may just seem like a patch of mud, but there’s a lot of detail in there.

See how many badger tracks you can find!

Frosty fields

Frosty fields

Well, we’re ten days into 2009, and so far the only way to describe the year is ‘cold’.

The temperatures have not been much above freezing for two weeks, with night-time temperatures as low as -10 degrees Celsius.

I spent the New Year on the North Wales coast.  Normally this part of the country is quite mild, as the sea acts as a huge storage heater and keeps the temperatures up.  This year, however, the sand on the beach was frozen solid, and even the rock pools had a thick layer of ice.   It was really cold.

Chinese Water Deer in a frosty paddock

Back in Bedfordshire, the weather has been even colder.  Since most of our house has no heating we’re regularly having to scrape the ice from the inside of the windows in the morning.  We go out each day with a kettle of hot water to defrost the water in the chicken’s drinker, as it freezes solid overnight.

I’m not complaining,
mind you.  It’s quite fun to dress up in warm clothes and get outside, and I’d much rather have this sort of cold, clear weather than the murky drizzle we get so often.

Tracking is almost impossible at the moment, as the ground is like stone.  I came across a fresh fox track on December 27th, just before the frost started.  It is still there today, and looking almost as fresh, fossilised in the hard, icy ground.

The best thing that happened this week was on Monday, when it snowed.  It was only a couple of inches or so, but it got me more excited than you can imagine.  This is the first snow since I started learning tracking, and I was itching for the opportunity to go out and look at the tracks.  I had visions of being able to follow perfect crisp tracks for mile after mile, and to see the full pattern of animal movements written across the snowy ground.

I was working for a long day on Monday, but on Tuesday I managed to get out for an hour or so in the early morning before work.  There were already thousands of tracks from the previous 24 hours.

Here’s an easy one to start with.  Here’s the tracks of our cat, Mayfield.  She was originally a farm cat, and she’s not at all put off by cold weather.  Here you can see the print of her back legs as she sat in the snow.

The cat sat on the... snow

Our local fox has been quite active lately.  As long as he keeps away from my chickens then I’m happy to have him around.  Since the chickens have a de-luxe high security run (which they still escape from every now and then), there isn’t much danger to them.

Here’s the fox’s tracks.  Note that the fox, unlike the dog, has an almost perfect register.  This means that the rear feet go into the tracks left by the front feet, so the track looks like they have two feet rather than four.  You can see here that there is only slight overlap to show that there are two prints on top of each other.

Fox tracks

Fox tracks

The vast majority of tracks were from rabbits.  In fact, there were so many rabbit tracks that they obscured almost all the others.  Here is a classic rabbit track.

Rabbit track

Rabbit track

The direction of travel in this case is from left to right.  The two small prints close together on the left are the front paws, and the larger tracks on the right are the rear paws.  When hopping, the rear paws ‘overtake’ the front paws, leaving a track that seems backwards.

Some of these rabbit tracks are quite impressive.  Look at the tracks immediately above the stick.  There are two sets of rabbit tracks – one at either end of the stick – representing a single bound.  Ignore the trail going from bottom left to top left, and the one across the top of the picture.

Bounding rabbit tracks

Bounding rabbit tracks

The direction of travel is from right to left, with the rear paws quite far ahead of the front ones. This rabbit was obviously bounding along at a fast pace.  The stride length was 120cm, which is a big distance for a rabbit to travel in mid-air.  Actually, the guidebooks give a stride length of 80cm for a rabbit, so this one must have been really sprinting.  It may even have been a hare, as hares have strides of up to 250cm, but the tracks themselves looked like the other rabbit tracks, so perhaps I’ve got a record-breaking rabbit on my hands.

Frustratingly, there were no badger tracks in the area.  I was longing for the chance to trail a badger through the snow, and to try and build up a picture of it’s nightly movements, but it was not to be.  Perhaps badgers don’t like snow.  The hard frost would mean that even a badger would find it difficult to dig up food.

I decided to have one last try at finding badger tracks before the snow melted, and after work I set off for the wood where the main badger sett is.  I had an idea that I might be able to find tracks in the pasture field, as I know they forage there and I’ve seen them in that area before.

I walked up to the wood at about 10.00pm (I worked late!).  The half-moon and the snow on the ground made it quite possible to wander around without a torch.  Unfortunately, by the time I arrived, the pasture field had been trodden over by the resident sheep, countless rabbits, and a solitary human.  Finding individual tracks was almost impossible.

On the borders of the wood though, I came across a trail that looked right for a badger, and I was able to follow it into the wood itself.  There, on the undisturbed snow, were two lines of badger tracks – one going away from the wood and one going back into it.

Badger track in snow

And there they were – a little distorted, but unmistakeably badger tracks.  It seems that only a single badger had been out foraging – the others probably had more sense and stayed warm underground.

I didn’t get the chance to follow badger trails as they wandered across a pristine field of snow, but it was fun to go out and look for them.  I hope that we get more snow this winter – ideally at the weekend – so I can go out and spend hours literally following in the footsteps of the wildlife.  In the meantime, may the Protector of All Small Beasts look after the animals and birds and see them safely through the cold spell.

I’ve always wanted to try plaster casting animal tracks.  I don’t know why, it just seems like an interesting thing to do.  I suppose it would be a useful skill if I ever come across a really rare track of say, a bigfoot or puma.  Neither is very likely in Bedfordshire, but you never know.  Anyway, today I gave it a go.

There isn’t much information on the internet on how to make plaster casts, so here’s a guide if you want to try it yourself.

Firstly, be prepared.  I used plaster of paris (available from the Hobbycraft chain of stores) but I’ve heard of people using decorating filler instead.  You’ll need plaster, water, a bowl to mix it in, and something to stir it with.  You’ll also need some way of making a dam around the track to contain the plaster.  For this I used strips of cardboard and rings cut from a plastic bottle.

Plaster casting kit

A lot of these things could be improvised in the field, but I wanted to be sure that I had everything I needed, and I wanted it to be clean, so I took it with me.

The next step is to mix the plaster.  I feel that this is a bit of an art and may take some practice.  Put the plaster in the bowl first.  It is best to add a little bit more than you think you’ll need.

Plaster first...

Now add the water and stir slowly.

...then add water

...then add water

The aim is to get a smooth and even consistency.  Add enough water to make it slightly runny.  You’ll need to stir it to get all the lumps out, but don’t stir it too vigorously or you’ll introduce air bubbles that may spoil the cast.

Stir carefully

Next, put a dam around your track.  Here’s one made from a strip of cardboard clipped together around a deer track.  Push it into the ground slightly, but be careful not to distort your track.

Then add the plaster.  This dam is made from a section of plastic bottle and is around a badger track.

Pour the plaster in carefully so it runs into all the little nooks and crannies of the track, and don’t pour it in from a height in case you damage the track.

Leave for 30 minutes or so until the plaster is hard, and then it should be ready to carefully lift out.  It’ll bring some soil with it.  Leave this soil in place for the moment.

Lifting off the cast

Wrap the cast carefully and bring it home.  You’ll need to remember to bring a lot of plastic bags, as you’ll need to wrap up your messy bowl too.  If you’ve used a plastic bowl you can easily clean this when the plaster has dried by flexing it to break off the plaster.
