The TERFS method was created and tested in New Hampshire, and it has been used successfully in many locations around the world.

This method has been used to plant small areas at a relatively low cost in an attempt to determine if a site is suitable for seagrass growth before spending considerable time and money on a large-scale restoration. This method is also used when water is contaminated by environmental pollutants which are harmful to swimmers or divers but not necessarily to the plants. Using TERFS, seagrass can be restored without risking the health of divers that would otherwise be used to transplant adult plants to these small areas. Finally in areas of high disturabnce, these frames protect the plants from being ripped out before they are well rooted in the sediment.

On a large scale, this method takes much of time and money. Each frame has four bricks attached, so it is quite heavy and bulky. Large boats and a lot of person power must be used to deploy many of these frames. Since the frames are relatively small (1/2 m2), many frames must be used to plant a large area.
