Created this on September 26, 2006 for better understanding of invasives, especially how they affect California ecosystems. Pictures and further text to follow. --Roland303 18:05, 26 September 2006 (UTC) Pictures added, references too. Is it ok not to list a bibliography or literature cited at the end? Pleas let me know.--Roland303 19:53, 28 September 2006 (UTC)
