The Pacific Northwest (PNW) is renowned for its diverse and vibrant forest ecosystems, characterized by a unique interplay of climate, geology, and biology. Stretching from Northern California to British Columbia, this region encompasses temperate rainforests, coastal woodlands, and mountainous terrain. The climate, influenced by the Pacific Ocean, brings abundant rainfall and mild temperatures, fostering lush vegetation and rich biodiversity. Key species include towering Douglas firs, Sitka spruce, and western red cedars, which create dense canopies that support a myriad of understory plants, fungi, and wildlife. 

The ecological dynamics of PNW forests are shaped by a variety of factors, including soil composition, elevation, and human impact. The nutrient-rich soils, particularly in older forest stands, support complex plant communities and contribute to high levels of productivity. These forests are also home to a wide range of animal species, from large mammals like elk and black bears to countless bird species, amphibians, and invertebrates. Interactions among these organisms, including predator-prey relationships and mutualistic partnerships, create a balanced ecosystem that is resilient yet sensitive to environmental changes.
