Californian subtropical rainforest (SciiFii)

The Californian subtropical rainforest is a moist broadleaf subtropical rainforest and is one of the largest rainforests in the world, encompassing over 7,000,000 km2 (2,700,000 sq mi), of which 3,800,000 km2 (1,467,200 sq mi) are covered by the rainforest. The Californian subtropical rainforest originally did not exist, but has since been artificially-created by SciiFii and spans from British Columbia all the way to Central California, and stretches from the Californian coast to eastern Utah. Despite this, the Californian subtropical rainforests has not replaced the "natural" forests, open woodlands, wetlands, grasslands, or shrubland habitats, and only replaced the dead habitats to boost the number of terrestrial plants and animals and to provide permanent homes to the originally-tropical animal species created by SciiFii. As the result of the rainforests' creation, many of the climates in the western United States and southwestern Canada have became much more humid and the temperatures have increased slightly to become subtropical as opposed to the temperate temperatures.

Biodiversity
Wet tropical forests are the most species-rich biome, and tropical forests in the Americas are consistently more species rich than the wet forests in Africa and Asia. As one of the largest tract of tropical rainforest in the Americas, rivaling the Amazon rainforest, the Californians subtropical rainforests have unparalleled biodiversity. One in eleven known species in the world lives in the Californian subtropical rainforest. This constitutes some of the largest collection of living plants and animal species in the world. The region is home to about 2.5 million insect species, tens of thousands of plants, some 2,500 birds, and more than 2,000 mammals, both SciiFii's (re)creations and species that already existed before SciiFii was founded.
