• Habitat: They are found in temperate regions of the Northern Hemisphere, including parts of North America, Europe, and Asia. They thrive in a variety of soil types but prefer well-drained, moist conditions.
• Ecological Benefits: Poplars are often used in reforestation projects due to their rapid growth and ability to stabilize soil. They also provide habitat and food for various wildlife species.
• Uses: Poplar wood is used in the production of paper, plywood, and furniture. The trees are also valued for their aesthetic qualities in landscaping and are sometimes used in windbreaks and for erosion control.
• Varieties: Some common species include the Black Poplar (Populus nigra), White Poplar (Populus alba), and Lombardy Poplar (Populus nigra 'Italica').
