Space Invaders

This 24×36 inch poster, suitable for framing, explains how non-native invasive plants can alter the natural ecosystem, leading to the demise of native plants and animals. “Space Invaders” features photos and information on six non-native plants that have caused widespread problems in the Bay-Delta Estuary and elsewhere.

The poster also provides ways boaters, fishermen and others can help prevent the spread of these plants – such as landscaping with native plants – and provides a list of websites for more information. The poster’s development was funded by a grant from the CALFED Bay-Delta Program. Look for the Space Invaders and Unwelcome Visitors posters set in this section and get both posters for $8!

Discounts also are available on orders of 10 or more. Contact the Foundation at 916-444-6240 for more information.

It’s Not Just Nutria — Sacramento-San Joaquin Delta has 185 Invasive Species, But Tracking Them is Uneven
WESTERN WATER NOTEBOOK: Delta science panel urges greater coordination, funding of invasive species monitoring

Water hyacinth choke a channel in the Sacramento-San Joaquin Delta.For more than 100 years, invasive species have made the Sacramento-San Joaquin Delta their home, disrupting the ecosystem and costing millions of dollars annually in remediation.

The latest invader is the nutria, a large rodent native to South America that causes concern because of its propensity to devour every bit of vegetation in sight and destabilize levees by burrowing into them. Wildlife officials are trapping the animal and trying to learn the extent of its infestation.
