I was inspired by Mr.SamuraiSword's thread on why Sabal palmetto never seem to get really really tall on the shores on the beach. DCA_Palm_Fan suggestion that erosion may be a factor, so that makes me wonder, what is the best palm for erosion control? I heard they are used along riverbanks inland with Sabal minor, any other palms good for it?

Saw palmetto is about  as good as you can get. Allogoptera Arenaria does a great job too from what i hear.

I don't think of any palms as being good for erosion control.  After storms, the plants that persist, holding some sand with them are things like sea grapes, sea oats and maybe beach naupaka.  Of course this is at the beach.  Mangroves would seem to do a good job in bay and intracoastal areas.  Along riverbanks, not sure.  Maybe grasses would be amongst the best, followed by other vegetation which would have to be native to whatever area of the country the river is in?

Hmm.

Fascinating question.

Wouldn't have a clue about the beach, but away from it, it would seem that any "rooty" palm might be good. Queens, CIDP, Chamaerops. The only problem is you'd need a lot of them.

Cocos nucifera is very good at holding together beachfronts. Our local council chopped a number out from one of the local beaches and during the next tropical cyclone the beach was badly eroded.

I've heard that here in East Hawaii back when sugar cane was king, the plantation owners planted Archontophoenix alexandre

by the thousands to stabilize the steep slopes of the many gulches between cultivated areas providing drainage from the high rainfall. 

These slopes are now impenetrable forests of palms, both beautiful and invasive, and seedlings come up everywhere much like Washies do in Southern California. 

The small seeds can lodge themselves in the smallest of cracks and gaining a foothold is no problem.
