British power plant burns old growth Canadian forest destroying wildlife habitat

The Drax power plant near Selby, North Yorkshire, UK has been receiving a couple of sets of government subsidies worth £6bn because it is claimed that the electricity produced by this powerplant comes from burning plant biomass - trees from ecologically unimportant areas in Canada. 


In this instance, biomass is renewable organic material from trees. It should also be carbon neutral with the carbon produced from burning wood being cancelled out by the carbon absorbed by trees growing.

But the problem with this process is that Drax is receiving subsidies in order to burn wood from old-growth forests which provide a unique habitat for ecosystems in Canada. It's probable, that these forests provide a habitat for the Canada lynx which is my connection to the cat in this article.

In the UK, in 2017, in a sustainability report, Drax promised not to take timber from no-go areas which means protected forests, primary forests, old-growth forests and forests classified as having a high biodiversity value.

Government support for Drax can only be justified because the wood that they use for their power stations has been sourced sustainably and I presume in compliance with good carbon neutral policies. And in compliance with wildlife conservation. That's not mentioned in The Times article: Power plant burns rare forest wood.

The wood comes from primary forests as mentioned and therefore Drax should not receive government subsidies which have amounted to £6 billion as I understand it in the past.

In a letter to The Times British Members of Parliament have said the following: 
"Continued wood burning biomass harms forests, communities and contributes huge amounts of carbon emissions to the atmosphere."
In response, Drax did not deny clearing old-growth forests for its power stations. However Drax said that its 2017 report was "not a policy and is now obsolete." It's been superseded by 2019 document they say. A spokesperson for Drax said: "We are confident our biomass is sustainable and legally harvest and meet the requirement of our 2019 sourcing policy."

Comment: the company is wriggling out of their responsibilities. Sorry by entirely typical of big business.

Secondly, it seems extraordinary to me that Drax and the UK government can even contemplate chopping down forests and burning them in power stations in the UK. How can that be a good policy? 

That would seem to go totally against the fundamental principles of being carbon neutral. In preserving nature. In preserving habitat for wildlife. In doing the right thing. In protecting the planet. How does this Drax policy in partnership with the UK possibly enhance sustainability, nature, and protect the planet?

The UK government should be as ashamed as Drax. Typical of double talking big business in league with unethical British politicians. I hate them all.

Andean Mountain Cat Ecology and Behavior

This cat is not well known. Of all the wild cats of South America it is one of the least known.

As mentioned in the description section this cat is found in the high Andes. This is a rocky and cold place. The cat lives at altitudes in the order of 3 to 5,000 meters above sea level. The vegetation is sparse and hardy. The temperatures are low.

The Andean mountain cat is believed to feed primarily on mountain viscachas (a type of rodent that looks like a rabbit - see photo below), rabbits, armadillos and rodents. It also feeds on birds, ducks, seed snipes and wading birds. In Peru a survey found that the sightings of Andean cats by villagers corresponded with the presence of viscachas.

The Andean cat has been observed hunting in the daytime but is believed to be crepuscular (dawn and dusk hunter).

It has been possible to get close to this wildcat when observing it. It appears not to have learned to fear humankind. The snow leopard is similar. This makes the cat vulnerable to being killed by local people.

African Golden Cat Ecology and Behavior

It should be said that not enough is known about this cat to describe its behavior with absolute certainty. The African golden cat shares habitat with the larger leopard. This dictates available prey to an extent.

Habitat

The African golden cat is a forest dwelling cat. This cat lives in a wide variety of forest habitats. It's short tail indicates that it is a ground dweller, however. This cat prefers forest habitat along rivers "including mangrove and alpine bamboo forests". It can be found in montane forest and at elevations of 3,000 meters above sea level.

Prey

The African golden cat hunts at dawn and dusk (crepuscular activity). In research studies its prey items normally include small mammals and birds.

Average weight of prey items: 1.4 kgs; of which birds represent 18% (plucked).

Examples of prey are as follows:

Ruwenzort Mountains (East Africa): groove tooth rats, swamp rats, hyraxes and duikers.

Ituri Forest, Congo: 6.7% of 60 samples showed dwarf or pygmy antelope. 25% of samples showed a diet of blue duiker and 1.7% of samples showed bay duiker. The duiker is a medium-sized antelope. Overall: small to medium sized rodents make up 70% of prey.

Dzanga-Ndoki National Park, Central African Republic: 23.5% of the diet was blue duiker from 17 samples.

Other prey of this wild cat are:
  • monkeys
  • birds
  • livestock including goats, chickens and sheep
  • guinea fowl
  • francolins (a bird)
Social Organization

Solitary cat. Little is known. All cats keep home ranges and protect it with scent marking and scraps. Feces are left uncovered as a scent mark. Vocalizations are unknown but will include the usual hiss, meow, growl and purr.

Reproduction

Study on reproduction is from observing captive cats:
  • Female came into estrus at aged 11 months.
  • Gestation: 75 days.
  • Two litters of two cubs observed.
  • Newborns weigh 180-235 grams while at 40 days old they are able to chew chicken flesh.
