Pine marten roundup

For any readers who do not know what a pine marten is, the above will give you an idea. It is an arboreal predator (that is, it hunts in the trees). There are a total of 8 species of marten across the world. Historically, this was the second most common predator in the UK, with only the fox being more common.

Unfortunately, its habit of taking chickens lead to it being hunted ruthlessly. At the current time, it hangs on in Wales, and has a significant population in Scotland. In Ireland, the recovery is far further along.

In the UK, one of the reasons that we miss this little predator, is its impact on grey squirrels. Unlike the pine marten, the grey squirrel is not native to the UK, and its presence does much damage, from its impact on trees, and other plants, to the fact that it carries a disease which wipes out the reds rapidly (so they are incapable of living alongside each other). This is a species which I have followed closely, and while other matters have stopped me blogging on this species as often as I would like, it has not stopped me from reading about it, so you will find summaries of a variety of stories below.

 

 

Reintroduction project in Dartmoor: 15 pine martens were released in secret locations within Dartmoor in September. A total of 7 conservation organisations have been involved in this translocation. It is a total of around 150 years since pine martens were last in the area, but the translocated individuals are settling and slowly dispersing across the landscape.

To the right you will find a tiktok video which will give you details on this reintroduction.

While there is no idea where the pine martens came from, they appear to be doing well, and as the video shows, are breeding. While they have not been there long, so there is little evidence yet, it is highly likely that the pine marten arrival will be bad for local grey squirrel populations (a non-native squirrel which does much damage to UK woodland). This is an area of excitment and should be followed closely.

Pine marten spotted on Longleat estate

Pine marten caught on camera trap in Longleat estate in Wiltshire. It is unclear where this individual came from, lying half way between the forest of dean and the new forest (but far from both), but it is thought it has arrived naturally. While red squirrels would not be able to reappear in this part of the country, without help, as all surrounding areas have grey squirrels, should the pine marten survive, it is likley to greatly impact the local popualtion, and create an island, into which red squirrels could eventually return.

Pine marten in the forest of dean

Pine marten were translocated from Scotland into the forest of dean, beginning in autumn of 2019, when 19 were introduced, and a further 35 joined them in the next 2 years. Last summer, there was an estimate of 60 living in the forest, which while not a big increase, it has not fallen.

While the forest of dean covers just over 200 square miles, it is thought that 60 is roughly the carrying capacity. That suggests that the pine martens in the forest of dean need roughly twice as much space as elsewhere, so time will tell if the population can grow beyond this level. Still, it seems likely that this number of pine martens should be able to eradicate the grey squirrel, or at least greatly reduce its number in the area.

The below video shows 3 cubs from around 4 years ago.

 

Pine marten in the forest of dean

Research is being done on whether pine martens can live in timber forests – which account for a lot of forest in Scotland

Some simple changes may well allow timber and pine martens to flourish alongside each other. Across 1 woodland, a number of nest boxes have been added, which appears to be helping. The plantations are also looking at letting some older trees stay standing, as these are where cavities appear, which is the pine martens natural home. This research is being carried out in the forest of Ae and around Castle O’er.

Pine martens have turned up in a London cemetery, in area of England where they have not been seen for 150 years 

The Zoological Society of London ZSL (London Zoo)  already had a project in the area with remote cameras, as it is a stronghold for the hedgehog (unfortunately, another species with a horrific decline in the last 20-30 years). It was just one (and this was in 2022, so may well be gone), but it is exciting that such a small area can house an animal like this.

The Forest of dean, is 80 miles away, which is the nearest population, so it is thought that this might have to be the result of an illegal translocation (they are being translocated, but should be done by professionals, with checks and more.

Pine marten recovery is further along, and helps understand how it will work in England, particularly in cities (not the safe zone once thought)

 Once almost extinct, for similar reasons in the UK (habitat destruction, and persecution) in 1976 they were given legal protection, and at the same time, forestry started to expand once again. The pine marten is how living in around 45% of Ireland.

The red squirrel is recovering as a result. There was a fear that grey squirrels would survive within cities, as pine martens are generally to shy to venture into even large parks within cities. However, what has been found, is that the abundance of squirrels in cities is a mirage – there are only sustained by populations outside the city, therefore, should places like the green belt around London get settled by pine martens, it is likely that the London squirrels would disappear within a few years.

Similar to elsewhere, pine martens have now also been introduced to the Lake district.

Just how endangered is the Vanuatu dugong? First survey since 1988 underway

The quiet bays in the Melanesian archipelago are perfect for the sea grass meadows, which in turn means that it is fantastic for dugongs – animals also known as sea cows. Just a few years ago, these animals were a regular sight. Growing up to 4m long and 400kg, just a few years ago, it would not be an unusual day when you would see one of these animals in both the morning and afternoon. Now they are rarely seen.

Officially, they are only classed as vulnerable (one of the lowest forms of endangered), but given how long it has been, it is unclear how the population is doing. However, unfortunately, given fishermen (and other people on the wate), are encountering them so rarely, it is likely to have got worse. Dogongs in this area behave differently to Australia where they have huge seagrass meadows, so this full survey is certainly required.

It would be another area, where a growth in the ecotourism industry (ethical – not damaging the animals or stressing them) could be fantastic. Many surveys done on sea mammals, take on tourists to reduce their cost. Personally, I will always look for a research boat, as they want to be there, and will not go out if there is no chance of sightings.

The next-door population of New Caledonia was recently downgraded to endagered, and the east African population is classed as critically endangered.

Globally, the threats to these animals include gill-net fishing, boat traffic, coastal development and even hunting. Unfortunately, climate change is also a threat – rainstorms are becoming far more common, and these are damaging the seagrass, alongside cyclones.

Currently, it is estimated that the world looses 7% of its seagrass meadows each year. This should be concerning, as sea grass has a roughly equal ability to draw down carbon dioxide to land rainforests – so the more we loose the harder it will become to halt global warming. It should also be noted, seagrasses grow more healthily with dugongs present – help keep seagrass beds healthy by grazing on them, which controls their growth and disperses their seeds. This process is called “cultivation grazing”. The benefits on seagrasses include growth control (rapid growth can be bad for the long-term survival of the seagrass), disperse seeds (often with some ‘fertilizer’, which can help the seeds grow particularly well- and like various plants and elephants, seeds that have gone through a dugongs digestive tract is more likely to grow than those that do not), Improve genetic diversity (dugongs move between areas of the meadow, and take seeds with them) and help recovery after cyclones (by connecting areas of the meadow, reseeding meadows in danger from elsewhere where they are doing alright).

Unfortunately, this makes the dugong a keystone species – therefore, its loss would have a very negative impact on the whole ecosystem. Other species that rely on seagrass including sea turtles, manatees, a wide array of fish, many sharks are born in the seagrass, including lemon sharks nurse sharks, and bull sharks. A wide array of birds are similarly reliant.

EJC has ruled against Austria on wolf hunting

Wolves have only recently returned to Austria, with an estimated 80 wolves spread throughout the country. It is perhaps not surprising therefore, that animal welfare activists, took the government to court, when it set cull numbers at 20, or 25% of the population a year.

The Austrian government had pointed to a condition in the 1992 EU directive on protecting wildlife, which states that wolf hunting to prevent financial damage can only be done if the population is in a favourable conservation status – something certainly not true in Austria. This condition can only apply to a wolf population which is stable.

I would also suggest that plans to kill 25% of the population each year, should also damage this, but this is a discussion for another day – when the population is far larger than it currently is. Other countries like Holland have similar sized wolf populations, and so this ruling could be applied in a variety of places.

Regional governments have absurdly argued that the wolf is no longer endangered in Austria, and that therefore its protection should be reduced. had the government listened would a ruling similar to the USA have come forward? Such that open season could be declared?

It is a good thing that wolves are so good at holding on, as we have spent much of our time attacking.

It is funny to think, that it is estimated our relationship with wolves (in the form of domesticating them as dogs) likely goes back to a similar point to the advent of growing crops, and well before the time that we started to keep livestock.

Given our fondness of dogs has deeper roots than our fear of wolves, it seems odd, that wolf persecution ever really got underway. It is true that wolf populations do need handling, but their existence is more good than bad. Places like the UK where they are missing, show this (when looked at the situation rationally)

Australias environment could be fixed for 0.3% of GDP

Wentworth Group of concerned Scientists estimate that for just $7.3 billion a year for 30 years, most extinctions could be avoided as well as repairing soil and restoring rivers. That sounds like quite a lot? Well, invasive species cost the Australian government $24.3 billion a year now.

Recovery of some of the endangered species, could well save more than they cost to save, in reducing this invasive species bill. This would also improve agricultural output, as a result of improved soil health.

Near-extinct Siamese crocodile making a recovery

The Siamese crocodile is recovering in Cambodia, with 60 hatched babies this year – more than at any time this century. Five nests were found by locals at the end of June with the eggs that resulted in these crocodilians. Thought extinct, until being rediscovered in Cambodia they have made an impressive recovery since 2012 when the project started, with 196 of this species returned to the wild in the last dozen years.

Local community wardens regularly cross the mountainous area, to check on them. In recent times, they have been observed in new territory, suggesting that their population is growing again naturally.

Hundreds of giant tortoises have returned to the wild across the Galapagos

It is thought that the Galapagos housed a population of roughly 200,000-300,000 giant tortoises, before humans arrived. This compares to a population of around 15,000 at the current time. Rangers have been trying to boost the rate of recovery, by taking eggs from the wild, raising the tortoises in captivity and releasing them, when their survival is more likely – with 560 animals returned to the wild in 2023 (it should be noted, that wild this is an impressive number, at that rate, it would take several centuries for the population to fully recover).

The project (Iniciativa Galapagos) aims to rewild 15 species across the range, including the giant tortoise, iguana and wandering tortoise.

America is following in Europe’s footsteps, with their recovering brown bears – now they are moving into human areas

This is a video of one of the clashes that I am talking about. The Grizzley bear population in 1975 ( in the lower 48 states) was just 700-800 (this excludes Alaska, where the current figure is 30,000) . The lower 48 states population has grown to around 1000 or an almost 50% increase.

There is a problem with this. Both in and out of Alaska (as well as Canada) these bears need space, and so are colonizing land that they previously roamed. Unfortunately, people rapidly forget how to live with animals like grizzly bears, so it is taking some significant work to live alongside these large animals once again.

The problem is, that when those encounters spike, generally authorities panic, and this generally leads to them looking to allow hunting once again. THIS IS DESPITE THE FACT THAT THE POPULATION IS NO-WHERE NEAR RECOVERED AT THE CURRENT TIME.

Could the recovery of the Goshawk save the red squirrel?

European Goshawks were extinct in Britain at the end of the 19th century (and remained rare for over half a century) but in the last 50 years have made an incredible comeback. In the new forest, in the south of England, there are thought to be hundreds of pairs living wild.

In Thetford forest in Norfolk, an estimated 52% of the goshawks diet was grey squirrel. While it is true that they will also take red squirrels, these are generally better at escaping. More importantly, it is thought that Goshawks could be used to stop the grey squirrels population from growing any further.

As I have written before, the pine marten is also important for the recovery of the red squirrel, as it is far more successful at hunting grey squirrels, and they generally do not cohabit in any part of the country.

This will likely not eliminate the direct need for grey squirrel population to be culled by humans, far from it, but may well help towards the idea of giving red squirrels breathing room.

4 new cheetah cubs born in Saudi Arabia, 40 years after extinction

The cheetah cubs of Suadi Arabia

While cheetah are now thought of as an African species, this has not always been the case. Within the lives of living people (admittedly, now quite old), the cheetah was lost from India. This occurred back in 1952. The last cheetah was seen in Israel was 1959. There are a range of countries which the cheetah was lost from in the 20th century. Further back, cheetah lived in the USA and other far flung countries.

Now, it is true, that the Asiatic cheetah is on the verge of extinction in its only home of Iran, with just 12 estimated in the wild in 2022, down from 100 in 2010.

While at times, the government of their only home have made positive noises about saving the Asiatic cheetah, they have also bothered those working to save them, including lengthy prison terms for those working in the field.

Should wolves in Europe have their conservation downgraded? Are they really stable enough to be hunted again

The European commision has proposed downgrading the protection of wolves from their current strictly protected, but it has been suggested that this is not based on any science.

A total of 9 countries (The call for a re-evaluation of the annexes of the EU Habitats Directive is included in a note put forward by Finland with the support of Austria, Czechia, Greece, Italy, Latvia, Romania, Slovakia and Sweden, ahead of the EU Agriculture Council meeting of 23 January).

The problem with this move, is that while in some countries like Romania, there is a large and healthy wolf population, in other countries like France it is a very different matter. If there is a change in their status, it needs to be assessed country by country, and the European Union must really require minimum levels, otherwise, this move is highly likely to lead to the extinction of the wolf across much of Europe once again.

While living alongside wolves is not always simple, it is essential to have predators to control populations of prey, such as deer. This is not something that is easily replaced by culling, and in the UK, the likely reduction in car collisions with deer would save far more than the cost of compensation for the occasional livestock that might be lost (of course, the wolf is not currently wild in the UK and the current government sees no reason to change this).

While complicated, the interest in the wolf is high, and it is highly likely that farmers would be able to supplement their farming income by money they could be paid through ecotourism and allowing people to try to see the wolves from their land. Wolves as with many other species are still slowly recovering from centuries of persecution, they are needed for our ecosystem to flourish, and can be good for everyone, with adjustments and compensation for loss of livestock.
