O Mongo

(Swietenia macrofylla Kin

Conhecido também como aguano, cedrorana, araputanga. cedroí e mogno-brasileiro, o mogno é certamente uma das espécies brasileiras mais val iosas, devido a beleza de sua madeira e a facilidade com que pode ser trabalhada na fabricação de móveis. Estas características aumentam sua cotação no mercado internacional, e conseqüentemente sua exploração nas florestas onde ocorre. Esta exploração em grande escala acabou colocando em perigo de extinção a espécie no nosso território (Portaria IBAMA no 37/N de 13 de abril de 1992).

O mogno ocorre desde o México, passando pela América Central, Venezuela, Colômbia, Peru e Brasil. No Brasil é uma espécie amazônica, ocorrendo no Acre, Amazonas, Pará, em Mato Grosso e Goiás.

A árvore possui uma folhagem densa, com uma ampla copa, que confere a esta espécie valor ornamental. A árvore adulta possui altura entre 25 e 40 metros, podendo algumas vezes atingir 50 metros de altura e mais de 1 ,5 metro de diâmetro. O tronco é retilíneo, podendo apresentar sapopemas. A casca é espessa, de coloração cinza externamente e avermelhada na parte interna,apresentando-se bastante sulcada. As folhas são alternas, pinadas, paripinadas, de 6 a 12 pinas, e glabras. Suas flores são pequenas, esverdeadas e escondidas entre os ramos. Os frutos são grandes, ovóides e destacam-se sobre a copa. Quando maduros, abrem-se em 5 partes, liberando as sementes aladas, que são dispersas a grandes distâncias.

O mogno floresce de outubro a dezembro, logo após brotação intensa de folhas novas, e frutifica de agosto a novembro.

Após a frutificação, a copa reveste-se de folhas novas.

O maior problema para o cultivo desta espécie em plantios homogênios éo ataque de Hypsipyla grandella, uma mariposa que deposita seus ovos na gema apical da planta. Os ovos eclodem e as larvas causam broca e conseqüente morte do ponteiro. Quando a planta consegue sobreviver, produz vários ramos laterais, o que torna a sua madeira inadequada para a indústria.

Also known as "aguano", "cedrorana", "araputanga", "cedror' and "mogno-brasileiro", the mahogany is certainly one of the most valuable Brazilian species, due to the beauty of its wood and how easily it can be handled in the making of furniture. Such features increased its price in the international market and, consequently, its exploration in the forests where it appears. This large scale exploration has turned the mahogany into an endangered species in our territory. The mahogany appears in Mexico, some areas of Central America, Venezuela, Colombia, Bolivia, Peru and Brazil. In Brazil, it is considered an Amazon species, appearing in the States of Acre, Amazonas, Pará, Mato Grosso and Goiás. The mature tree is around 25 to 40 meter high, although it may reach 50 meter high and 1.5 meter of diameter. Its flowers are small, greenish and hidden among the branches. The fruits are big, ovoid and, the ripe ones open in five parts, spreading far-reaching seeds. The mahogany flowers from October to December, right after its intense leafing, and fruits from August to November. After fructifying, the foliage is renewed. The biggest problem for the homogeneous raising of such species is the attack of Hypsipyla grande/Ia, a moth which lays its eggs on the plant's apical gemma. These eggs brake into larvae of a bug which causes the death of the leading twig. Whenever the plant manages to survive, it produces several lateral branches, which makes the wood improper for industry.
