Brazil has a monitoring system to track annual forest conversion in the Amazon and most recently monitor Cerrado biome. However, there is still gap of land use cover (LULC) information all Brazilian biomes country. Existing countrywide efforts map lack regularly updates high spatial resolution time-series data better understand historical dynamics, subsequent impacts country biomes. In this study, we described novel approach results achieved by multi-disciplinary network called MapBiomas...
Mimosa tenuiflora is a native pioneer tree from the Caatinga used commercially as firewood due to its high calorific value. It deciduous, trunk does not reach large diameters and it has good regrowth capacity. This study intended determine annual increment in diameter of M. correlation with rainfall, basis for fuel wood management. Disks stem base trees were collected 2008 Sertânia Serra Talhada, Pernambuco State, coppiced 2003 Limoeiro do Norte, Ceará plantation established 2002. The have...
do povoamento, em uma área manejada após corte raso.
A demanda de uso energético da vegetação Caatinga tem gerado modificações nas paisagens e perda diversidade biológica por insuficiência informações sobre o manejo das espécies. Considerando fato estacionalidade climática ser um fator influência na sobrevivência, ritmo biológico, rebrota produtividade plantas, neste estudo objetivou-se avaliar a sazonalidade sobrevivência produção biomassa Caesalpinia pyramidalis Tul. (Caesalpiniaceae). Para tal, foram selecionados aleatoriamente 180...
Visa identificar a composição da renda e principalmente contribuição do manejo florestal sustentável. Estuda dois assentamentos no Município de Serra Talhada, sertão Pernambuco, sendo um com outro sem manejo. Tomando como base o ano 2008, levanta todos os custos benefícios das atividades produtivas junto cinco famílias em cada assentamento, bem outras fontes despesa. Demonsta rentabilidade negativa para as agrícolas pecuárias quase totalidade dos casos incapacidade remuneração trabalho...
There is a growing demand for wood products from forests located in dry regions, which includes the Caatinga, biome Northeast Brazil. This study evaluates relationship between volumetric production, energy potential, and rotation cycle. Information was collected forest stands different stages of regeneration an arid region Based on management plan, four fields were selected with post-logging ages 9, 11, 13, 16 years. inventory recorded circumference at chest height, base total volume, stored...
Abstract The steppic savanna term was originally employed to classify a single type of tropical vegetation in Africa, but it has been expanded by the pioneering RADAMBRASIL authors and is currently used Caatinga northeastern Brazil, other types with similar characteristics Amazon Chaco/Pantanal areas. Here, we propose that use name describe semantically structurally incorrect since its definitions conflict between main (steppic savanna) subclasses (e.g., forested savanna), rendering them...
The objective of this work was to determine the energy density in three different areas under sustainable forest management Rio Grande do Norte (RN).From access inventory each area, selection species with 70% representativity based on importance value index (IVI) carried out, as well knowledge about real volume wood.From species,
Background: Managed Caatinga forests in Northeast Brazil are an important source of wood products, however, successful regeneration and regrowth is to guarantee sustainability these forests. The main objective this study was evaluate the natural forest ability a under varying clear-cut treatments, as well estimate recovery time stand parameters. Results: An experiment set up Petrolina, Pernambuco state, Brazil, comparing five strip widths: 0, 40, 60, 80 100 meters. Forest inventory data...
Resumo -O objetivo deste trabalho foi avaliar diferentes comprimentos de transecto para determinação da necromassa florestal caída sobre o chão.Os dados são provenientes transectos 10 metros, medidos durante teste metodologia do Inventário
RESUMO: Na década de 60, em vários locais do país, foram instalados pequenos talhões experimentais espécies florestais nativas e exóticas, entre elas Paubrasilia echinata, com o objetivo avaliar comportamento das mesmas condições plantios homogêneos, sendo que anos depois grande número dessas parcelas ficou sem manutenção foi abandonada. Assim, deste trabalho resgatar informações silviculturais apresentar resultados da espécie homogêneos realizados na zona litorânea Região Nordeste,...
