Shortly after World War II, The British began planting Genuine Mahogany (Swietenia macrophylla) in plantations. Over the last 60 years the plantation owners have been shocked with how fast the stock grows and more importantly how aggressive the natural replanting spread is. Today there are 3 and even 4 generations of Mahogany trees growing in Fijian plantations that are very healthy and managed in a sustainable way. These plantations are firm believers in low impact forestry and strategic thinning to produce strong primary stock. Strict replanting guidelines are in place but more often than not are not necessary because of Mahogany’s penchant for spreading.
