Total percentage of carbon in the soil sample was determined using LECO furnace combustion CN analyses at the CSU Soil, Water, and Plant Testing Laboratory. Species richness was calculated as a count of all unique species, including native species, non-native species, and those not identified to the species level based on 2016 vegetation monitoring. Data represents the 07/17/20 version of the data set, with a sample size of 141. However, fast-growing plants tend not to live long and when a plant dies, all the carbon in the plant is broken down by insects, fungi and microbes and released as CO again. Source: Data was collected as part of the City of Boulder's Open Space and Mountain Parks grassland monitoring program and 2018-2019 externally funded soil monitoring. Vegetation and soil management can enhance natural carbon sequestrationthe process by which atmospheric carbon dioxide is taken up by trees, grasses, and other plants through photosynthesis and 4 Allen, J.G., et al. By that measure, bamboo might be the best at sucking up CO. Note that in grasslands where native species richness is higher, there is also higher soil organic carbon. Regardless of whether you have 1,000 or 100,000 square metres, this is what grass is doing in this analogy: it takes carbon from the atmosphere every year, but that carbon is going straight. This makes Miscanthus vital in maintaining soil stability and facilitating the long-term sequestration (carbon capture) and storage of atmospheric carbon. When wildfires cause trees to go up in flames, the burned carbon they formerly stored is released back to the atmosphere. Water infiltration could improve, meaning less surface runoff. (Joe Proudman/UC Davis) Carbon up in smoke Unlike forests, grasslands sequester most of their carbon underground, while forests store it mostly in woody biomass and leaves. The first is improved soil structure, with surface structure becoming more stable and less prone to crusting and erosion. As management changes, benefits might appear in several ways. and manure) to soil and the selection of high yielding grass species mixes for increasing carbon sequestration where this is possible to apply.
