The King Alfred Dianella Caerulea “John 316” PBR protects against erosion.

Ozbreed erosion control

A recent study has shown that plantings of King Alfred Dianella Caerulea “John 316” PBR can be an effective solution to erosion problems. In the study, King Alfred strengthened soil a record 752% or 70 kPA. To put that in perspective, it is similar to two-dimensional biodegradable jute mats, except that King Alfred strengthens the soil five centimetres deep, providing three-dimensional soil protection.

King Alfred is a proven plant for use on slopes and stream banks. Research also showed that King Alfred has excellent tolerance to salt spray, wet conditions and drought. It tolerates grey water better than many other similar plants.
