Apart fro areas of the Congo and Amazon rainforests, and areas of Siberia canada and the Sahara, virtually all other ecosystems have been adversely affected.
Many ecosystems look intact, until we realize that important members from these ecosystems are missing. It is unfortunately true that humans are almost always responsible for these holes in the food web.
The asiatic lion only continues to exist in the Gir national park. When this area was first protected, the lion population had fallen very low, some saying a matter of only a couple of dozen remaining members. In the 50 or so years since the population has multiplied well. Now are said to be around 400, spread across 1 contiguous protected area (under a number of different authorities – Gir Sanctuary, Gir National Park, Pania Sanctuary, Mitiyala Sanctuary, and Girnar Sanctuary. The first 3 form the core, with the others lying within dispersal range.
Indian Lions do look incredibly similar to African lions, however are different in important ways
The problem is at these three have a combined area of about 561 square miles, which is an incredibly high density for lions.
At the end of last year, the people of Colorado have voted to reintroduce wolves to the state by 2023. It should be noted that a wolf has been collared in the state in the last few months. It came from a neighbouring state, and therefore clearly wolves would return on their own eventually.
The proposal squeaked across the line with 50.4% of the vote. Now, this decision is complicated by Trumps foolish move to delist wolves throughout the USA, despite their current position. Estimates of the number of wolves in the USA when settlers arrived, range from 250,000 up to 2 million. Even if we assume the low end of the range, the current wolf population of the lower 48 states in the USA is just 6000, a number that we can safely say is at the most, roughly 2% of historical numbers.
Walrus are thought of as an arctic species, and indeed this is where they are found in their greatest numbers. However, they once had a greater range. Walrus have been extinct here for 3000 years, however the UK is part of their natural range, if an extreme southerly point.
Back in 2002 there were only 94 Iberian lynx left in the wild. This wild cat had declined for a number of reasons, unfortunately all down to humans.
Wild Iberian lynx: tourism visits to see these cats have increased over the years.
The main threat to Iberian lynx was the loss of their main prey. Back in 1952 a doctor, fed up of rabbits overrunning his garden, introduced Myxomatosis. Myxomatosis is an illness, which kills rabbits. Within 2 years this illness had spread across Spain, and eventually went on to reduce the population by 95%.
Rajasthan madlyya Pradesh and Gujarat are all looking at potential sites were cheetah could be reintroduced. Given the precarious state of the cheetah population in Iran (thought to only be 50-60 animals) the reintroductions would come from Africa.
Once common across the whole of the UK, they were hunted to extinction. Currently, just a handful remain in Scotland. While interbreeding between wildcats and feral domestic cats is normally rare, in the current situation feral cats outnumber wildcats 1000 to one, and as such the wildcat is essentially extinct.
Could wildcats roam an English county once again – as early as next year?
The farmer who is looking to reintroduce them, currently has 6 pairs, which he is hoping to increase to 150 individuals and to start reintroducing perhaps as early as next year.
Despite the fact that British citizens have done much good work towards to conservation of wildlife and wilderness in the world, we have been less successful in the UK. Having largely eradicated a small arboreal predator from much of the UK, we then decided to introduce the grey squirrel from the USA.
Bangor pine marten – 4 were reintroduced a year ago, and seem to be doing well
Spending more time on the ground, and being far less agile than their red smaller cousins, grey squirrels cannot coexist with pine martens.
The UK has been predator free (at least large predators that can threaten humans and have to regularly kill to survive) for roughly 300 years. Wolves disappeared around 300 years ago, bears are thought to have gone extinct around 1,000 years ago and lynx are thought that have gone extinct about 1,300 years ago.
Wild lynx can be incredibly impressive when seen, but most of the time they are not seen even by though whose job means they spend their time in the same habitat. Not that people don’t try, lynx are charismatic animals and people will spend much time trying to get a glimpseContinue reading “A second attempt to introduce lynx into Northumberland is being proposed”
The decline of the Asiatic lion occurred long before the decline of the African lion. Within the last 200 years lions were found across Asia into parts of eastern Europe. In ancient times they were even found in large parts of the Iberian peninsula, so from the furthest east of Asia to the furthest west of Europe. Continue reading “A second home for Asiatic Lions”
