Ardilla Gris Oriental

Native to eastern North America but successfully introduced to Europe and other regions, the eastern gray squirrel is a medium-sized arboreal rodent weighing up to 600 g. Highly adaptable, thriving in forests, parks, and urban gardens, gray squirrels cache thousands of nuts and seeds each autumn, inadvertently planting trees through forgotten caches. In Britain, they have largely displaced the native red squirrel by outcompeting them for food.

Common Spruce

<em>Picea abies</em>, commonly known as the common spruce or Norway spruce, is a large coniferous tree in the family Pinaceae, native to the mountains and boreal forests of Europe. This species typically inhabits montane and subalpine forests, as well as lowland boreal zones, growing on well-drained, acidic, cool and moist soils. Its geographic range extends from Scandinavia and the Baltic states across central Europe and the Alps to the Carpathians and Balkans, with widespread plantation cultivation throughout the temperate Northern Hemisphere. Classified as Least Concern on the IUCN Red List, <em>Picea abies</em> is one of the most economically important forest trees in Europe, widely grown for timber, pulpwood, and as Christmas trees. Individual trees can reach heights of 50 metres or more and live for several centuries, with some specimens exceeding 500 years. The species produces characteristic pendulous cones up to approximately 16 cm in length, the largest of any European spruce. As a plant, dietary traits in the zoological sense are not applicable. Biological traits such as average lifespan are highly variable and well-documented for managed plantations, though precise natural lifespan data across unmanaged stands remains incomplete. The species provides essential habitat and food for numerous forest invertebrates, birds, and mammals.
