Biomass equations for Brazilian semiarid caatinga plants

Abstract: RESUMO -(Equações para estimar a biomassa de plantas da caatinga do semi-árido brasileiro). Equações alométricas foram desenvolvidas para estimar a biomassa aérea viva (B) e a área de projeção da copa (C) de dez espécies da caatinga, com base na altura da planta (H) e/ou do diâmetro do caule ao nível do solo (DNS) ou à altura do peito (DAP). Trinta plantas de cada espécie, cobrindo a faixa usual de diâmetros (3 a 50 cm), foram medidas (C, H, DNS, DAP), cortadas na base, separadas em partes, pesadas e subamostr… Show more

“…As for the estimates of aboveground biomass (Figure 3), it was observed that the validation was consistent when using the equations of Návar-Cháidez (2009a) and the local equation of Sampaio and Silva (2005) for all species. The equation of Abreu et al (2016), although local, was not indicated to validate the biomass estimates.…”

“…According to forestry experts, an assumed average rate of growth of DGL of 4 mm per year from age 12 on could then yield a 20 yr value for DGL of 412 mm. We then used an allometric equation of Sampaio and Silva (2005) for Jatropha mollissima in Brazil to calculate the most likely biomass at 20 yr. This equation predicted that the average dry biomass would be 140 kg per tree above ground and 55 kg below ground.…”

“…No Brasil os modelos preditores de fitomassa florestal, a partir de métodos destrutivos, concentraramse nas Florestas Amazônicas (Klinge et al 1975, Uhl & Jordan 1984, McWillian et al 1993, Kauffman et al 1994, Santos 1996, Higuchi et al 1998, Nelson et al 1999, Nogueira et al 2007, Nogueira et al 2008. Em menor número, encontram-se os modelos desenvolvidos para outros ecossistemas, tais como: Cerrados (Delitti & Meguro 1984, Castro & Kauffman 1998, Abdala et al 1998, Delitti et al 2006, Caatinga (Sampaio & Silva 2005), Mata Mesófila Semidecídua Ciliar (Moreira- Burger & Delitti 1999), Manguezal (Soares & Novelli 2005) e Mata Atlântica (Burger & Delitti, 2008).…”
