US has tightened African elephant trophy import rules but stops short of banning

Elephants hunting used to be a common activity. This was banned in Kenya in 1973 and in Botswana in 2014. The trade in Elephant parts was banned in 1989.

For many years, however, conservationists have called for rich countries to ban imports of hunting trophies on a country by country basis. This is for a simple reason – a reserve like the Kruger, has a real issue with a growing elephant population, yet at the same time Nigeria has only 400 elephants left. Tanzania has seen a reduction of elephants of 63%, while Mozambique has seen a reduction of 34%.

This new ruling suggests that imports are only allowed from populations which are large enough to support the loss. Now, I would be interested as to how this is worked out. For instance, could I buy a tiny parcel of land, on the edge of a large reserve, and allow any elephants that step on my land to be hunted?

  • Somewhere like the Selous game reserve, would in theory be acceptable for elephant hunting. If we go back to the 1976 there were approaching 109,000 elephants. However that population is now thought to be around 13,000 – hunting should be banned until the population has recovered. If a hunting reserve cannot afford to police well enough to eliminate poaching, it should not be allowed to hunt (the number of poached and hunted elephants must be below safety levels.
  • The Serengeti ecosystem also does not have a large elephant populatino so cannot allow hunting
  • The African forest elephant is considered critically endangered, so none of these elephants should be hunted

Could Bison allow the land to reduce air pollution? – Yes

A small herd of 170 bison, released into a 20 square miles area of Tarcu mountains in Romania, are estimated to allow the land to capture 59,000 tones of carbon each year.

Big animals like this, stimulate the soil and plant growth, allowing the soil and plant growth to take up far more carbon than without them. Although Romania is one of the wildest countries in Europe, the European Bison was lost around 200 years ago. Between 2014 and 2021, 100 bison were reintroduced into the area, and that population has naturally grown such that there are now 170.

Scientists estimate that the lands carbon storing potential is as much as 10 times greater with the bison (they suggest that it is between 5 and 15 times more carbon.

Analysis has found that 1/3 of land set aside for restoration is worse than before in Australia

Large parts of Australia look like the above photo, beautiful in a rugged way, but quite useless for the survival of many of Australia species. Australia has a wide range of habitats, which means that there are many areas which need to be protected.

The problem is, according to this study, declaring an area protected appears to be having little change on what is happened.

1/3 of all land that is set aside for restoration and conservation, has got worse rather than better. Given the fact that so many species are just hanging on to existence, this could be very bad news.

In one area that was studied, the majority of the area was cleared paddock – a serious problem for the koala and grey-headed flying fox which called the area home.

In particular, the idea of this scheme is so called biodiversity offsetting – if you are to clear wildlife habitat, you protect a similar sized area elsewhere.

Deforestation in Columbia has fallen 36% in a year

Rainforest is essential if we are to combat climate change. Therefore every fall in deforestation is fantastic news.

Of course, it should be noticed, that this is still a loss of 792 square km of forest from the year before – we need to reach zero forest lost per year, but every step towards this target is positive.

The former higher rate of deforestation has its roots in the chaos caused by the fall of the largest guerrilla group the Farc, which disbanded in 2017.

Columbia is considered the second most biodiverse, is fighting to be a leader in the fight against climate change. Of course, this needs to continue to fall, and indeed have large areas replanted, if we are to avoid much of the climate change, but one step at a time

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.

Might the solution to deforestation be education? probably not everywhere, but clearly here in Sumatra

Camp Granit – Sumatran rainforest (not the same place)

There is a variety of different causes for deforestation. However, the majority of the work is usually done by individuals – often for subsistence farming, though often the land is only fertile for a short period of time, requiring more rainforest to be cut down.

However, if people on the ground know that cutting down the rainforest will make life worse, then they will not do it.

Efron Simanjuntak (click here to see a photo in a new window) was once a successful logger (illegally) in Sumatra. In 2017 he was caught, and in 2018 he was imprisoned for 2 years. In these two years, he had a lot of time to think, and realized the damage that he was doing.

Currently, in the Amazon rainforest, 5 times more carbon is released from degradation than from deforestation – and still what remains continues to burn

A study, using detailed 3d surveys, found that road building, and other degradation is causing 5 times as much carbon to be released into the air, than deforestation of the Amazon.

From road building, to selective logging, fires and natural disasters, all these activities are combining to having a greater impact on carbon stocks in the Brazillian Amazon than deforestation. This huge discrepancy is not taken into account by the numbers.

This is also a problem to the world, as this carbon is being radically underestimated, which means that large quantities of our remaining carbon budget are being used up. This new survey used lidar, which gives a more accurate idea of what is left in terms of forest cover.

With the addition of lidar sensors on the ISS, it is possible to scan the worlds forests more often – and given the ISS regular passing over 90% of the earths surface (in each 24 period – as while it orbits on a set path, the earth turns below it) this can be a good tool to keep an eye on the forests of the earth.

Another confirmation (as if it was needed) has been supplied by this study, showing that Indigenous territories and conservation units are both more efficient ways to protect the forest. These cover only 47.5% of the land, but contain just 9.1% of the forest clearing 2.6% of the logging and 9.6% of the fires.

Talking of fires

Fires continue to burn in the Amazon, with over 13,400 having been recorded in 2024. President Lula has called for general mobilization and Brazil has pledged to end deforestation by 2030. This is higher than during Bolsonaro’s time in office, though current cause is a drought, not human mismanagement.

Climate change is causing an increasing change in weather patterns, and reduced rainfall is changing the forests behaviour ( it should be noted, that the forest produces a not -insignificant portion of its rainfallm

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.

Older trees are more capable of increasing growth and carbon dioxide use than young ones

Whether tropical or not, old growth forests absorb far more carbon than new trees, and can increase this

Old growth trees, have the capacity to greatly increase their growing rate, when there is a lot of carbon dioxide in the air. This has been found, in a study by the University of Birmingham. This is important, as in many places around the world, an area of destroyed natural forest, is considered to be replaceable by a similar area of planted trees, but what is clear, is that in order to merely keep up with the absorption of the original trees, several multiples more of trees need planting. What is worse, is that this is not worrying about the huge amount of carbon that is stored in the trees that are cut down, or within its roots system and the surrounding soil.

To put this in perspective, at the current time, it is estimated that a football pitch of primary forest is lost every 6 seconds.

This experiment was done, by piping extra carbon dioxide into a forest area and monitoring its growth. Unfortunately, this does reinforce the conservationist point of view, that simply planting a similar area of woodland for each bit lost, is not good enough.

Dublin zoo has to get breastfeeding women to educate an orangutan

A female orangutan, who had failed to bond with either of her first two offspring (and as a result had both died), found 30 volunteer human mothers, to come in to breastfeed their babies in front of the orangutan.

The exhibit was shut, so that the mothers could breastfeed topless – allowing Mujur the 19 year old mother to be, to see what was happening. As can be seen from the image, the orangutan showed a great deal of interest in the breastfeeding – and as well, Mujur was shown videos of orangutans feeding their babies.
