carbon storage

Trees do plenty of work to sequester carbon on their own, but many forests are not as healthy as they should be due to fire suppression and climate change. This can leave trees vulnerable to large scale insect damage, fire or drought, and much of the carbon stored by forests is lost to the atmosphere as trees die.

The U.S. Forest Service is committed to the storage of carbon using wood products through the green building and wood products strategy. This strategy involves putting people to work in rural communities, enhancing resiliency of our ecosystems, and sequestering carbon by promoting the use of wood products in large building construction.

Staff from USDA’s Natural Resources Conservation Service (NRCS) from Washington, D.C. and Portland, Oregon visited California recently to meet with state officials and farmers and ranchers to discuss how farms and ranches can store carbon, reduce greenhouse gas emissions and potentially benefit financially by providing greenhouse gas offsets under California’s cap-and-trade program.

Also along for the trip were researchers from Colorado State University, who partnered with NRCS to develop USDA’s greenhouse gas accounting tool called COMET-FARM. The tool enables producers and technical specialists to estimate the beneficial impacts of implementing conservation practices that store carbon or reduce greenhouse gas emissions.

For the past 3 years, I have worked with a team of experts and scores of reviewers on a report published today, Quantifying Greenhouse Gas Fluxes in Agriculture and Forestry: Methods for Entity-Scale Inventory.

If you are a landowner, scientist, or conservationist looking for new tools to estimate carbon storage and greenhouse gas (GHG) fluxes, you will want to take a look at this report.  It provides the scientific basis and methodology to assess the GHG benefits of conservation practices and farm, ranch and forest management. This information will help producers gauge progress in building healthy, carbon-rich soils and, ultimately, more resilient production of food, fiber and fuel.

The Prairie Pothole Region of North Dakota, South Dakota and Montana provides sanctuary to millions of nesting waterfowl each summer. With an innovative partnership led by Ducks Unlimited (DU), USDA is helping to provide new opportunities for agricultural producers in the region to sequester carbon while cultivating new revenue streams.

With the help of a grant from USDA’s Natural Resources Conservation Service, these partners have created a carbon credit system for private landowners in North Dakota who agree to avoid tillage of grasslands. Grasslands store carbon dioxide, one of the leading greenhouse gases contributing to climate change.

The North Dakota Prairie Pothole project, funded by a USDA Conservation Innovation Grant (CIG) of $161,000, provides potential new revenue streams for landowners while avoiding greenhouse gas emissions and increasing carbon sequestration.

Whether they are ringed by wrought iron or suspending a swing, urban trees are first and foremost trees. In fact, they are all working trees.

Consider, for example, carbon storage. From New York City’s Central Park to Golden Gate Park in San Francisco, America’s urban trees store an estimated 708 million tons of carbon, valued at $50 billion. Annually, these trees absorb an estimated 21 million tons of carbon, a value of $1.5 billion.
