| This two-year-old (and 60 cm tall) mahogany sapling (Sweitenia macrophylla, Meliaceae) has seeded into a mahogany grass pasture about 200 m downwind from its mother, a mother that today 15 years later has all of her wind-dispersed seeds knocked out of the air by much younger nearby trees. The grass appears to offer little competitive problem for this tree seedling, but offers huge problems if human-set fires are allowed to burn through it. The rootstock of a sapling of this young age and size generally does not survive a severe grass fire, and certainly would not have survived a fire following its first year of life. | ||
