Changes Of Climate And Fire Regimes - 1132 Words

When both changes of climate and fire regimes were simultaneously accounted for, on average, the climate scenario RCP2.6 resulted in the highest values for NPV, size diversity and total carbon stock under all management intensities, and the highest species diversity under most intensities. In year 2100, in general, the 20-year cutting cycle led to higher total carbon stock and size diversity but lower NPV and species diversity. Low-intensity management caused the highest total carbon stock (10 years: 823 – 854 ton ha-1; 20 years: 864 – 888 ton ha-1) and size diversity (10 years: 1.93 – 2.11; 20 years: 1.95 – 2.10) but the lowest NPV (10 years: 9,318 – 9,955 $ ha-1; 20 years: 3,426 – 4,056 $ ha-1) and species diversity (10 years: 1.28 – 1.31; 20 years: 1.18 – 1.22). Lower total carbon stock (10 years: 778 – 814 ton ha-1; 20 years: 800 – 828 ton ha-1) were expected with medium intensity but satisfactory species diver sity (10 years: 1.50 – 1.53; 20 years: 1.36 – 1.39), size diversity (10 years: 1.47 – 1.59; 20 years: 1.91 – 2.02), and NPV (10 years: 18,721 – 19,812 $ ha-1; 20 years: 7,749 – 9,596 $ ha-1). High intensity resulted in the lowest total carbon stock (10 years: 740 – 775 ton ha-1; 20 years: 768 – 794 ton ha-1) and size diversity (10 years: 0.89 – 1.02; 20 years: 1.27 – 1.40), but the highest NPV (10 years: 26,749 – 27,440 $ ha-1; 20 years: 13,302 – 13,757 $ ha-1) and species diversity (10 years: 1.58 – 1.61; 20 years: 1.53 – 1.56) (Tables 2-4).

The scholars that are against these accusations argue that the change developed due to the effects of climate and low nutritional status of Australian soils. In addition, they also argue that the evidence provided by the scholars who think human affected environment are inconclusiveRead MorePine Forests Of The Colorado Plateau1222 Words   |  5 Pagesdisturbance regime known for this ecosystem (citations please) Since the 1930s fire ecology for ponderosa pine/bunchgrass forests has been extensively studied. As the single most important natural abiotic disturbance in ponderosa pine forests (Moir and Dieterich 1988; Moody et al. 1992; Covington and Moore 1994), fire establishes plant composition, succession, and forest structure. Frequent, low-intensity fires have been part of the ecology and evolutionary history, with crown fires seldom occurringRead MoreA Guide For Fire Regimes And Management Practices1737 Words   |  7 PagesIntroduction Fire is a natural part of most temperate forest ecosystems, and has a large influence on the productivity and biotic composition of the ecosystem. Prescribed fire has long been used as a tool for forest management throughout Australia, and elsewhere around the world, to maintain or restore species and habitat, to enhance post-logging recovery, and to reduce fuel loads and associated wildfire hazards (Bennett et al. 2013; Spies et al. 2012). While fire is commonly used for managementRead MoreEffects Of Soil Carbon Sequestration ( Scs )880 Words   |  4 Pagessources or sinks. About 46% of vegetative carbon and 33% of soil carbon is found in the tropical rain forest (Fisher and Binkley). SCS is affected by soil texture, soil moisture (drainage), soil temperature, pH, C: N ratio, vegetation cover, nutrient regime and climatic conditions. The importance of soil carbon sequestration.

While many of Australia’s native flora has adapted to live and reproduce under certain fire regimes, uncontrollable wild fires and changing fire regimes are detrimental to both the Fauna and flora or Currawinya (Queensland Government , 2001). Patchwork burning maintains community structure as a result of the variation in fire size, ages and distribution with the added benefits of preserving wildlife and impeding uncontrolled wildfires in which endanger parkRead MoreClimate Changes And Climate Change Essay1691 Words   |  7 Pages Climate is average patterns of temperature, precipitation, humidity, wind and seasons. Climate patterns play a significant role in shaping natural ecosystems, and human economies that depends on them. But the climate we have come to expect is not what it used to be. We know this from plenty of observation, documented in hundreds of journal papers and scientific research which has shown many evidence for rapid climate change.

Previous to suppression policies, ponderosa pine and dry mixed-conifer forests experienced a frequent, low- to mixed-severity fire regime (Agee 1996, Allen et al. 2002). As a result of a century of fire suppression, successional trajectories have been significantly altered, in that ponderosa pine and dry mixed-conifer forests have become increasingly dense with late successional, non-fire-adapted trees and excess accumulations
