The Northwestern Coniferous Forest is located in the Pacific Northwest of America. It ranges from the northern border of California to the southern border of Alaska. has harsh cold winters and warm summers, but stays cool year round. As a result of cool temperature and low evapotranspiration rates, the soil moisture is high. Mineral soils here are very thin. The diversity in this biome is very low. It has firs, pines, cone bearing softwoods, giant redwoods, and spruces. The biome is too cold and too dry to support deciduous trees. The Northern part of this biome is covered in lakes, which eventually fill with with mineral and organic matter to form bogs. This region gets around 50 inches per year in the southern part of the biome. In the mountainous areas it gets around 200 inches.
