Alnus rubra (red alder) is a deciduous broadleaf tree in the Betulaceae (Birch) family native to western North America. Red Alder is the largest species of alder in North America and one of the largest in the world, reaching heights of 20-30 meters. The official tallest red alder (1979) stands 32 meters tall in Clatsop County, Oregon (USA). The name derives from the bright rusty red color that develops in bruised or scraped bark. The bark is mottled, ashy-gray and smooth, often draped with moss. Large trees are often unbranched for a considerable distance from the ground. Description from Calscape

The plants, animals, fungi, microbes, and other natural features that make up “urban habitat” are important to the character, function, and livability of cities.
Take a virtual tour of Capitol hill with naturalist and author David B. Williams and gain a new appreciation of the nature of the city and its wild side.
Get involved by sharing and mapping the birds, animals and nature around you to help the community understand the biodiversity in our neighborhood.
Learn about the diversity in pigeon populations in the United States and the implications of this variability on the species.
Learn about container gardening with shrubs, trees, herbs, veggies, perennials, and annuals. A special focus will be on plantings that provide pollinators with food and that encourage bird habitat.
Some introduced plant species can diminish biodiversity. Other plants produce poisons that can harm wildlife. Learn what plants to avoid when figuring out what to plant or remove in your outdoor space.
Nature of Your Neighborhood is a collaboration between Birds Connect Seattle, the Capitol Hill EcoDistrict, and the Seattle Bird Conservation Partnership. Our goal is to foster relationships between the people and the nature of their neighborhoods.
