[PCA] Eelgrass propagation and restoration planting in the Pacific NW

[Russ Cohen]

Fyi just in case you haven't already seen this and it might interest you
and/or others you know (see

Here's an excerpt from the article: 

 

This [Eelgrass restoration] process involves harvesting flowering shoots
from nearby areas and using two methods to reseed the restoration site. The
first method involves placing flowering shoots in nets suspended above the
sediment. When seeds ripen, they fall to the bottom and germinate. For the
second method, scientists collect flowering shoots, culture them in flowing
seawater, and then collect ripe seeds. They then broadcast the seeds by
hand. Our partners anticipate that these methods will be more efficient than
the conventional practice of transplanting adult plants and could be scaled
up to restore larger areas.
