Responsible Landscaping

Many invasive plants were originally introduced as ornamentals. The horticultural industry, recognizing this threat to native habitats, joined conservation biologists at a national workshop in 2001 entitled "Linking Ecology and Horticulture to Prevent Plant Invasions." This workshop resulted in the "Saint Louis Declaration on Invasive Plant Species," describing voluntary codes of conduct for professionals and the gardening public. In 2002, Cal-IPC began developing its ability to educate the California horticultural community about invasive plants.

Cal-IPC developed "Don't Plant a Pest!" brochures to help homeowners and landscaping professionals select non-invasive plants. These brochures and associated webpages provide suggested alternatives to invasive plants. More info...

Cal-HIP partnership

In 2004, Cal-IPC joined with other NGOs, agencies, universities and industry trade organizations to form the California Horticultural Invasive Prevention (Cal-HIP) partnership. The partnership includes broad representation from nursery and landscaping communities, and develops voluntary measures to reduce the number of invasive plant species sold in California and prevent further invasions from horticulture.

PlantRight campaign

Cal-HIP partners developed the PlantRight campaign in 2007, including the PlantRight website. Cal-IPC is joining other partners in getting the message out to nurseries, landscape professionals and consumers. Weed workers can play a strong role in supporting this campaign! More info...
