“…In 2000, in the Amazon state of Brazil, about 75% of the timber for the plywood and veneer industry originated from floodplain forests (Lima et al, 2005). Timber species in the vá rzea are classified using a threshold of about 0.60 g cm À3 , into low-density and highdensity trees .…”

“…In Central and Western Amazonia 60-90% of the timber originates from floodplain forests (Kvist and Nebel 2001;Worbes et al 2001;Lima et al 2005), due to the easy access and the low costs for harvesting, skidding and transport of the logs (Higuchi et al 1994;Barros and Uhl 1995). However, such timber extraction concentrates on a few tree species such as Cedrela odorata, Calophyllum brasiliense, Ceiba pentandra, Virola surinamensis and Platymicium ulei.…”

Tree growth is a fundamental indicator for conservation plans of Amazonian floodplain forests. In this study we use dendrochronology to analyze wood growth patterns of Tabebuia barbata and Vatairea guianensis, two tree species occurring in nutrient-rich white-water (várzea, Mamirauá Sustainable Development Reserve, MSDR) and nutrient-poor black-water (igapó, Amanã Sustainable Development Reserve, ASDR) floodplain forests of Central Amazonia. From 20 trees per species and floodplain system (total of 80 trees) growing under a similar flooding regime with a mean inundation height of about 4 m we measured diameter at breast height (dbh). We sampled two cores per tree with an increment corer at the height of dbh to determine wood density (WD), tree age and mean radial increment (MRI) rates. The wood samples were macroscopically analyzed. Both tree species show distinct annual tree rings characterized by marginal parenchyma tissues. MRI was measured by a digital measuring device and WD was determined by the ratio dry mass/fresh volume. MRI of both tree species was significantly higher in the várzea than in the igapó, which can be traced back to the contrasting nutrient status. WD showed no difference comparing both floodplain forest types. Tree ages of a species for the same diameter are more than twofold higher in the igapó than in the várzea. To insure a sustainable harvest, felling cycles in these forests should be adjusted according to rates of growth.

“…A matéria-prima oriunda de desmatamentos, autorizados ou não, é a forma de mais fácil acesso e de menor preço, assim estimulando as empresas madeireiras a adquirirem madeira de corte raso ao invés da madeira proveniente de plano de manejo sustentável. Alguns autores acreditam que aliado a este fato, existe a ineficiência dos instrumentos de controle e fiscalização ambiental para detectar a atividade ilegal, o que favorece a extração predatória de madeira, diminuindo a competitividade dos produtos de planos de manejo florestal sustentável (ASNER et al, 2005;LIMA et al, 2005 (CUNHA et al, 2009). -VEIRA et al, 2013).…”

RESUMO Buscou-se realizar um diagnóstico do setor madeireiro de Rorainópolis (Roraima) visando gerar informações que subsidiem o desenvolvimento de políticas públicas voltadas para a gestão florestal no Estado. Foi aplicado um questionário em nove serrarias com o intuito de obter informações sobre localização atual e anterior, tempo de atuação; espécie, volume de madeira serrada e origem da matéria prima; o destino da madeira processada; o tipo de armazenamento e de secagem. As serrarias eram empreendimentos novos com no máximo 5 anos de atuação no município. Os empresários abordaram que as dificuldades são a burocratização do licenciamento ambiental e o alto custo das taxas de licenciamento. Dentre as espécies comerciais processadas pelas empresas entrevistadas destacam-se: Manilkara huberi (9.860 m³), Dinizia excelsa (9.235 m³), Hymenolobium excelsum (4.440 m³), Goupia glabra (3.880 m³), Erisma fuscum (2.170 m³), Qualea paraensis (1.350 m³), Protium sp. (1.000 m³), Clarisia racemosa (1.000 m³), Couratari stellata (320 m³), Bagassa guianensis (280 m³) e Handroanthus sp. (77 m³). A principal fonte de obtenção de matéria-prima foram os projetos de corte raso em propriedades rurais do sul do Estado. Os estados brasileiros aos quais foi destinada a maior parte da madeira processada de Rorainópolis foram Bahia, Ceará, Goiás e Amazonas, e observou-se a Venezuela como destino internacional mais relevante. Para secagem da madeira, quando realizada, o método utilizado é ao ar livre. Recomenda-se que é necessário criar mecanismos para desestimular a extração seletiva e predatória de madeira, legal ou ilegal, desenvolver meios para incentivar a prática do manejo florestal sustentável.

Characterization of the timber sector of Rorainópolis, south of Roraima ABSTRACT A diagnosis was made of the timber sector of Rorainópolis (Roraima) aiming to generate information that would support the development of public policies aimed at forest management in the State. The questionnaire was applied to nine sawmills in order to obtain information about current and previous location, time of operation; species, lumber volume and origin of the raw material; the destination of processed wood; the type of storage and drying. The sawmills were new enterprises with a maximum of 5 years of operation in the municipality. The businessmen said that the difficulties are the bureaucratization of environmental licensing and the high cost of licensing fees. The main commercial species processed by the companies interviewed were: Manilkara huberi (9.860 m³), Dinizia excelsa (9.235 m³), Hymenolobium excelsum (4.440 m³), Goupia glabra (3.880 m³), Erisma fuscum (2.170 m³), Qualea paraensis (1.350 m³), Protium sp. (1.000 m³), Clarisia racemosa (1.000 m³), Couratari stellata (320 m³), Bagassa guianensis (280 m³) e Handroanthus sp. (77 m³). The main source of getting raw materials were clearcut projects in rural properties in the south of the state. The main Brazilian states who buy the pro...
