English Ivy (Hedera helix) is an aggressive invasive plant that threatens the health of Pacific Northwest ecosystems. Originally introduced as an ornamental groundcover, it spreads rapidly, forming dense mats that smother native wildflowers, ferns, and young trees. As it climbs, ivy adds weight to trees, increases wind resistance, and can contribute to tree failure. Its thick foliage also prevents sunlight from reaching the forest floor, reducing biodiversity and disrupting habitat for native wildlife. Birds spread its seeds into natural areas, allowing infestations to expand far beyond landscaped yards. Removing English Ivy helps restore native plant communities, protect trees, and create healthier habitats for pollinators, birds, and other wildlife.

Butterfly Bush (Buddleja davidii) may attract butterflies with its colorful, nectar-rich flowers, but it is an invasive species that threatens native ecosystems throughout the Pacific Northwest. Originally introduced as an ornamental shrub, it produces large quantities of seeds that spread into forests, riverbanks, and disturbed habitats, where it can outcompete native vegetation. Although Butterfly Bush provides nectar for adult butterflies, it does not serve as a host plant for most native caterpillars, making it far less beneficial to butterfly populations than native alternatives. Its spread reduces biodiversity and displaces plants that provide essential food and habitat for native insects, birds, and other wildlife. Removing fertile Butterfly Bush and replacing it with native flowering shrubs helps restore ecological balance and supports pollinators throughout their entire life cycles.

English Laurel (Prunus laurocerasus), also known as Cherry Laurel, is an invasive evergreen shrub commonly planted as a privacy hedge throughout the Pacific Northwest. Although valued for its dense foliage and rapid growth, it readily escapes cultivated landscapes when birds disperse its seeds into nearby forests and natural areas. Once established, English Laurel forms dense thickets that shade out native wildflowers, shrubs, and young trees, preventing natural forest regeneration and reducing biodiversity. Its evergreen foliage allows it to compete for sunlight year-round, while its aggressive growth displaces native plants that provide essential food and habitat for pollinators, birds, and other wildlife. Removing English Laurel and replacing it with native shrubs helps protect forest ecosystems, restore biodiversity, and create healthier, more sustainable landscapes.

Running Bamboo (Phyllostachys spp.) is an aggressive, non-native plant that can quickly overtake gardens, neighboring properties, and natural areas throughout the Pacific Northwest. Often planted for privacy screening or its ornamental appearance, running bamboo spreads through extensive underground rhizomes that can travel well beyond the original planting area, making it extremely difficult to contain or remove. Its rapid growth creates dense stands that crowd out native vegetation, compete for water and nutrients, and reduce plant diversity. Unlike native shrubs and trees, running bamboo provides limited food and habitat for many native pollinators, birds, and other wildlife. Its spreading roots can also invade garden beds and damage landscaping. Removing running bamboo and replacing it with native trees and shrubs helps restore ecological balance, protect neighboring landscapes, and create healthier habitats that support local biodiversity.
