In March, 2007 Robert Wilson and Vaughn Seward started a series of linked haiku on subject of Nature haiku on the simply_haiku Yahoo haiku group. The concept is that whenever some one in the group replies to a nature-related haiku, it will be added to the archive. Others can add to this mini-series and it can grow as long as there is interest. As long as the "echoes" are nature-related and somehow relate back to the original posted haiku it will be added to the archive. Echoed haiku can also relate to any of the other echoes in the same mini-nature series and one can post more the once.
The following is the archives of this series (maintained by Vaughn Seward).
