Abstract
The production of illegal charcoal, associated with other local human practices, is responsible for the degradation of native forests, especially in the Brazilian Amazon. The need for market control and charcoal production is accompanied by the lack of comparative charcoal materials from the Amazon. Here, we describe charcoal samples of 21 Brazilian species and provide SEM images that can facilitate the charcoal identification. It is possible to distinguish the species on the basis of anatomy. Features such as vessel groupings, vessel–ray pitting, perforation plates, axial parenchyma, ray cellular composition, storied structure and secretory elements were chosen as primary diagnostic features for the identification of species. We highlight vessel groupings, axial parenchyma type and in some cases even perforation plates, which were easily observed in low magnification SEM images and can assist in the supervision by government agents. From our descriptions, evaluations and photomicrographs, it will be possible to compare charcoal from commercial species from the Amazon.
期刊介绍:
The IAWA Journal is the only international periodical fully devoted to structure, function, identification and utilisation of wood and bark in trees, shrubs, lianas, palms, bamboo and herbs. Many papers are of a multidisciplinary nature, linking
