This 24×36 inch poster, suitable for framing, explains how non-native invasive animals can alter the natural ecosystem, leading to the demise of native animals “Unwelcome Visitors” features photos and information on four such species – including the zerbra mussel – and explains the environmental and economic threats posed by these species.
The poster also provides ways boaters, fishermen and others can help prevent the spread of these animals – such as emptying the bait bucket in a garbage can, not in a waterway – and provides a list of web sites for more information. The poster’s development was funded by a grant from the CALFED Bay-Delta Program.
