Wlanders are a race of Humans from the planet Wland in the Pegasus galaxy. A peaceful people, they usually trade with many cultures in the Pegasus galaxy. They used to live in a town, also known as Wland, but it was attacked by the Wraith some time around 2009, so people had to settle on land outside the old town.
The Atlantis expedition sent a medical team, consisting of Jennifer Keller and Carson Beckett, to help the people and to provide them with medical supplies. (SGA: "Legacy: Homecoming")
