Mayotte: Psidium guayava is an exotic species, often cultivated for its fruits and widely naturalized in degraded dry vegetation.
New Caledonia: Currently, Psidium guayava is most often found in isolated shrub formations. When it is not controlled, it ends up forming thick groves. With a high ecological plasticity, the shrub thrives in almost all types of soil (except mining grounds) up to 1500 m altitude. It resists drought thanks to its very deep root system.

Global harmfulness
Psidium guayava is one of 300 major invasive species of tropical Australia and Oceania including New Caledonia.
It should be noted that Psidium guayava is a host plant for several insects harmful to fruit crops (fruit flies).
Local harmfulness
Mayotte: Psidium guayava is a frequent weed, it is present in 15% of cultivated plots. It develops especially in pineapple and ylang plantations. It is mainly present in the center of the island, but it can be found in the north and the south.
New Caledonia: Psidium guayava was introduced as a fruit tree in 1863; it has become a plague on pastures.
South Africa: Psidium guayava competes with and replaces native species. Dense stands along watercourses and the edges of wetlands are likely to consume large quantities of water.
