The loss of large trees is a global problem due to the indiscriminate cutting of timber and the opening of new areas for various human uses. Brazil presents many tree species and extensive forest areas covering different biomes. The species nut brazil and kapok are the giant trees of the Amazon. The jequitiba tree and the brazilian pine are among the largest Brazilian trees in the Atlantic Forest. The decline scenario of the population of large trees can be compared with data from the National Forest Inventory (NFI) in comparison to specific surveys of each species in the regional and national scenario. Santa Catarina is the first state to finalize its forest inventory. Few large trees were sampled in the NFI by systematic sampling. Brazil has trees with diameters greater than 3 m and historical records of 5 m. Recognition of maximum tree growth is important for the ecological management and tourism potential of giant trees. New researches and public policies should be developed for the cataloging and management of these resources in order to avoid permanent loss.
