This past week in invasive species blogging:
- Walking the Berkshires posts about finding Japanese barberry in an unusual place: a painting depicting the Civil War. There's also a follow-up post called "Barberrians at Gettysburg."
- bootstrap analysis does some indoor cat blogging about feral cats.
- far outliers notices the irony in the fact that American fish are invasive in Asia while Asian fish are causing problems in America.
