Trees stand as the largest living organisms on Earth and also rank among its oldest residents. Seasonal forests, distinct from tropical rainforests, represent the most extensive land habitats. A significant portion of the world’s trees thrives in the sprawling taiga of the Arctic north. In North America, forests showcase the towering sequoias of California, recognized as the planet’s largest trees. These majestic giants contribute significantly to photosynthesis and provide shade, creating a dynamic seasonal ecosystem that supports an array of plant and animal life.
