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.

Deforestation and palm oil stories: Deforestation is not a desire, there is demand for what is done with the land

The problem with stopping deforestation, is that for the majority of the world we are far removed from rainforests (from where I sit in the UK, I would have to travel 3250km (over 2000 miles) to the nearest rainforest, which is an area on mainland India). Indeed, rainforest is generally something that only survives in developing countries.

This means that, for most people, they either live far removed from the rainforest, and so cant see it impacting them, or they live near a rainforest, but are struggling to provide for their family and those around them. It is quite true that many people in both the first and third world would like the rainforest to survive – indeed, should you talk to people in the west, many are very worried about the survival of the great apes, who are rapidly loosing land.

The problem is simple. Those living in the third world are living hand to mouth, so unless they work in tourism, the rainforest is often an inconvenience that makes life harder.

In 2023 a total of 6.4 hectares of forest were destroyed – more than 25,000 square miles. However, more concerning is the fact that 62.6 million hectares of forest (almost quarter of a million square miles) was degraded – for road building, logging, and forest fires. Degraded land is often less good for carbon storage, as well as conservation of the worlds wild species. It is often, then not long, before someone comes along a removes the rest of the plants so that the land can be used for something else.

And what was this deforestation for (other than logs)? Beef, soy, palm oil paper and nickel.

The Brazilian Amazon is one of the bright spots, where since the election of Luiz Inacio Lula da Silva, deforestation has fallen 62%. Unfortunately, in the same time period, Indonesia’s deforestation is up 57%

It seems hard to see how the world will meet its goal of cutting deforestation to zero by 2030 as most countries have pledged. Also, despite reductions in deforestation, the Amazon has had one of the hardest years in terms of forest fires – something that only gets more likely as rainforests are lost, and climate change increases the temperature in many parts of the world. It is a sad fact, that there is often not a great deal of temperature difference between a rainforest which is functioning, and one that dries out and becomes a fire hazard.

Having said all this… a study in Indonesia has found that controlled low-intensity logging doesn’t have to negatively impact a forest in terms of carbon storage or food availability – this in turn means that much wildlife can survive.

The problem often is that if the land is in private hands, then low- intensity logging is not going to happen. If the landowner has decided to deforest, they will raze the land. In national parks, in theory low intensive logging would be possible, but this would require people to control the logging, and this is the issue that we have in the first place. Unfortunately, despite the pledge by 140 countries, deforestation is coming back.

In a related subject, the Indonesian president Prabowo Subianto has stated that palm oil expansion won’t deforest because palm oil has leaves. There are many issues with this, but perhaps primarily amongst them, when forests are cut down, they are usually replaced with grass lands for grazing cattle – these are also covered in leaves. This is obviously stupid – it may well be a better thing, that the rainforest is going to be replaced with plantations, but it has been shown that palm oil plantations take up a tiny proportion of the carbon that rainforests take up.

In another article, there was a finding that macaques living in palm oil plantations have an alarming infant mortality. Unfortunately, these macaques are not unique in being threatened by palm oil, but others include orangutans, elephants, tigers, pangolins, bonobos, and Irrawaddy dolphins.

While palm oil may be a better vegetable oil than other crops, it still looks like it will lead to us loosing most of our rainforests, unless a grip on this is found.

Toyota was a climate hero in the 1990s, why is it now to exact opposite?

I have spent a great deal of time, recently, working on a variety of areas of the website that I hope to become important in the near future (including members areas). During this time, I miss writing on these subjects, so I would open tabs on news articles that had caught my eye – when I turned my attention back, there were more than 1000 tabs. Several hundred are wildlife news, which I will deal with in the near future, but the rest have been grouped. There is a long video embeded in the bottom of the page, which gives similar information but in more detail, if you would prefer (produced by the electric viking)

This grouping is stories about Toyota, and its various moves which appear to clearly show their moves to make the climate worse not better.

Wildcat kittens born outside captivity in Cairngorms

Wildcats are native to the UK, but have been pushed to the brink of extinction by hybridisation with native cats – which come from the wildcats from places like Israel in the middle east. As a result of this, as well as trying to remove the feral domestic cats, and their descendants, they are trying to create pockets of Scotland, which would allow these cats to recover.

The natural behaviour of a British wildcat when meeting a feral cat, is to kill it. However, as these animals become rarer, even rare breeding events, can threaten the survival of the whole species. This behaviour also means that with careful planning, we should be able to reintroduce them into other parts of the country. There are a range of other wild predators lost over the last couple of millennia – and I hope to see the others return, but it is thrilling to know that a wildcat is once again living and breeding in its native habitat of the Scottish mountains.

These wildcats are thought to be the first born wild in Scotland for 5 years, after 19 wildcats bred in the Highland wildlife park, were released into the Cairngorms national park.

Beavers have been returned to the South-down national park after a 600 year absense

Having been released near Petersfield in the South of England, they will be tracked by a team of academics, to make sure that they survive and thrive.

These beavers will help with the rejuvenation of a wetland area on the river Meon. Currently, the area consists of a straight section of the river, with a sort of duck pond beside it, however, once the beavers get to work, this will change dramatically – turning the pond into a series of ponds, and making it suitable to house a wide variety of British wildlife.

As found elsewhere in the UK, the beavers are likely to have a rapid impact on water quality (for the better). A second pair were introduced to an estate near Basingstoke just last year (they had their first kits in September this year).

As in other parts of the country, these beavers will spread out from where they have been reintroduced (if allowed) and are likely to link up with other populations, such as the Devon beavers, within a small number of years – it seems likely that without a sustained attempt to remove the beaver once again, it is only a matter of time, before they spread to all parts of the UK.

Apart from the joy of knowing they are there, there are many positive impacts of their presence: they will reduce flooding (areas that they do flood with their dams, are places which we likely should not have built anyway), clean water and create habitats for many other creatures. Perversely, they have also been shown to help forests recover (by creating a mosaic of different habitats) and therefore should be a positive for the forestry industry in the UK, despite fears to the contrary.

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)

The island where the feral species is an elephant

Around the world, there are invasive species – from grey squirrels in the UK, to Macaques on Gibraltar, however, all these pale on comparison to having to live with wild elephants.

The elephants were bought to the Andaman islands in the late 19th century, to work in the timber operation, which continued until the last few decades. Thankfully, much of the forest in the islands survives – with some islands retaining almost 90% forest cover. This means that the elephants might well be able to thrive into the future.

The islands lie 850 miles from the coast of India, which means that while elephants would not have existed natively on the islands, there are many species which would be found in the same area.

Interview Island and North Andaman hosts these elephants – though they need to be watched, as a population of 100 elephants is already small, but if split between 2 islands, humans may well have to be helped to remain genetically varied enough to survive long-term.

While some have suggested that the elephants have damaged biodiversity, with some species having become less common, this ignores the impact of the timber extraction – it is far more likely that this is an impact of the many decades of pulling specific trees out of the forest.

Given the endangered status of the Indian elephant, this population is precious, but whether it can be left where it is long-term is something we do not know. There are still roughly 30,000 elephants in India, but the Andaman island elephants are going to need to be watch, long-term, to make sure that they do not damage species only found in their new home.

The EU restoration plan was postponed in March, yet passed in August – what will it do, and will the UK do something similar?

There is still large areas of wildernesses in places like Romania, but this needs to spread across the continent.

What will it do?

  • Restore at least 20% of the EU’s land and sea areas by 2030 
  • Restore all ecosystems in need of restoration by 2050 
  • Set legally binding targets for nature restoration in terrestrial, marine, freshwater, and urban ecosystems 
  • Maintain and increase urban green space and urban tree canopy cover 
  • Restore at least 25,000 km of rivers into free-flowing rivers by 2030 
  • Plant at least three billion additional trees by 2030 

This plan was dropped in March as a result of Hungary blocking it, as well as Austria and a variety of other groups. It is unfortunate, that often in order to meet an agreement, the environmental rules are often watered down so much as to become meaningless. It was cleared, after Austria changed its mind (it should be noted that the Hungarian MEPs were in favour and it is only the Hungarian government that got in the way – as they often are; unfortunately the leader of Hungary Victor Orban is not helpful, and is often the block for the EU. Whether this will change in the near future is anyones guess.

Still this will have to be implemented across the continent to be useful. Having said this, should it be successful it is likely to have a big impact.

The UK clean energy targets will be missed without £48 billion

The UK has set a hard target of 100% green electricity by 2030, but unfortunately, at the current time, its investments are not keeping up with its targets.

It is estimated that the UK need £48 billion to get to this target in time. This target would require a doubling of the onshore wind capacity, a tripling of solar power and a quadrupling of offshore wind capacity.

The current thinking, is that the UK is just half way to the wind energy target in 2030, however with solar it is worse. Currently we have roughly 15GW installed capacity, but it is predicted that we need 70GW to meet our target. Current progress suggests that we will hit 44% renewable by then, which is far short of the 69% that would be required.

What is worse, is that at this rate, gas will still account for 29% of energy which would be more than the individual contribution of Solar, onshore wind or offshore wind. It should be noted, that it is thought that meeting this target on time, will be worth far more in savings, but there does not seem to be enough urgency from the UK government to push this forwards.

It should be noted, that we have just had a change of government, and if Labour continues as it has started, we should get back on track.

In the summer, a government report found that the policies put in place by Rishi Sunak were only good enough to meet roughly 1/3 of the carbon reduction that we had pledged to make in the Paris climate agreement of 68%.
