The decline of the Red Squirrel in the British Isles

The gray squirrel is native to the United States and was introduced to parks in Britain and Ireland. They caused the local extinction.

The maps below show the ranges of Red Squirrel and Grey Squirell in 1945 and 2010 in Great Britain and Ireland.

The Grey Squirrel and the red squirrel are not directly opposing, and brutal conflict among these species is not a factor in the drop in red squirrel populations. But, the Grey Squirrel arrives to be capable of reducing the red squirrel population due to the following causes:

- Grey Squirrel transfers a disease, the squirrel parapoxvirus, that does not develop to influence their health but will frequently kill the red squirrel. In 2008, the number of red squirrels at Formby in England had decreased by 80% because of this disease, though the population is presently growing.

- Grey Squirrel can better digest acorns, while the red squirrel cannot efficiently obtain the proteins and fats in acorns.

- When the red squirrel is placed under pressure, it will not breed as frequently.


In the United Kingdom, the population has dropped to 160 thousand red squirrels or less (120 thousand are in Scotland). Outside the United Kingdom and Ireland, conflict from the Grey Squirrel has been witnessed in Italian Piedmont, where two pairs left from captivity in 1948. A notable decline in red squirrel populations in the area has been observed since 1970, and it is worried that the Grey Squirrel may extend into the rest of Europe.

Map of Fox Species Distribution

Foxes are small to medium-sized members of the Canidae family, which also includes wolves, dogs, and other related animals. There are about 37 species of foxes distributed around the world, and they inhabit a wide range of environments, from forests and grasslands to deserts and urban areas. Below is the map of fox species distribution  created by Reddit user isaacSW Here are some of the most well-known fox species and their distribution: Red Fox ( Vulpes vulpes ): The red fox is one of the most widely distributed fox species and is found in North America, Europe, Asia, and parts of North Africa. They are adaptable and can live in a variety of habitats, including forests, grasslands, and urban areas. Arctic Fox ( Vulpes lagopus ): The Arctic fox is found in the Arctic regions of North America, Europe, and Asia. They have adaptations that help them survive in cold climates, such as a thick coat that changes color with the seasons. Gray Fox ( Urocyon cinereoargenteus ): The gray fox

Moose population in North America

The moose ( Alces alces ) is the largest member of the deer family, characterized by its massive size, long legs, and distinctive broad, palmate antlers found in males. They have a dark brown or black coat and a humped shoulder. Moose are primarily found in the boreal and mixed deciduous forests of North America, Europe, and Asia. They are solitary animals, often found near bodies of water, and are herbivores that feed on leaves, bark, twigs, and aquatic vegetation. Despite their size, moose are strong swimmers and can run up to 35 miles per hour. The moose population in North America is shrinking swiftly. This decrease has been correlated to the opening of roadways and landscapes into this animal's north range.   In North America, the moose range includes almost all of Canada and Alaska, the northern part of New England and New York, the upper Rocky Mountains, northern Minnesota and Wisconsin, Michigan's Upper Peninsula, and Isle Royale.    In 2014-2015, the North American moo
