Brazil nut tree

Brazil nut trees (Bertollethia excelsa) are protected by law in Brazil, but it is very unlikely that trees left standing in cattle fields or soy beans plantations will remain safe or bearing fruit for long time. They are pollinated by Euglossine bees that remain in the forest for the flowers of certain species of orquid that male bees need in their reproductive system and dont grow on Brazil nut trees. On the top of that, big Amazon wind storms eventually drop the unprotected trees.
