By Tom Davis and Paul LohmanThe Washington Times/CBS Interactive by The Washington PostRedwood trees produce an average of 15 to 18 billion leaves a year, a third of the total trees in the United States, which are one of the largest sources of carbon dioxide in the atmosphere.
Redwood trees also play an important role in meeting the country’s annual demand for fresh water, and in providing fuel for transportation.
Redwoods also offer the ability to regenerate woody debris from logging.
They’re also a valuable source of carbon, and some research has suggested that the trees’ roots are a good source of greenhouse gas emissions.
In a new paper published online in the journal Nature Ecology and Evolution, researchers report that redwoods and other trees that have been genetically modified to produce less carbon dioxide could also be more resilient to drought, as well as to the effects of climate change.
Researchers found that redwood and other woody species produce less CO 2 when they produce less leaves per tree, but the amount of carbon released was the same in the redwoods as in trees with the same number of leaves.
In other words, the amount released from the redwood was equivalent to the amount in the trees.
In contrast, the trees in which the modified trees were grown did not release any carbon dioxide.
The researchers found that the carbon released from trees with modified leaves had a range of impacts, from lowering the carbon content of the soil to lowering the rate of photosynthesis.
In a similar way, their analysis found that trees that produce less water would have more water available to them and their roots, allowing them to grow faster.
The study was conducted by researchers from the University of California, Davis, the University at Buffalo, the California Institute of Technology and the University for the Science of the Earth.
It was published in the Proceedings of the National Academy of Sciences.
“These results provide evidence that tree modification can increase the resilience of trees in their natural environment,” the study’s lead author, Jennifer R. Wray, a UC Davis Ph.
D. student in plant and soil ecology, said in a statement.
“The study suggests that the effect of modified trees on carbon sequestration could be important for climate change mitigation.
We believe that the benefits of the tree modification are well known and will likely be realized through future research.”
While redwoods have a relatively low carbon content, the study shows that even if they had to replace all the leaves, they could produce more carbon than would be released by a forest with identical leaves.
“This is a very good example of the importance of tree modification in mitigating climate change,” Wray said.
“We’re looking at a species that’s been modified so it can produce more than the amount that it produces in its natural environment.
In addition, the carbon release is similar.”
While the study found that modified trees did not significantly alter carbon content in the soil, they did reduce the amount carbon stored in the tree, and that could potentially make it more difficult for the tree to withstand drought.
Redwoods have been in use in the U.S. since the mid-1800s, and the trees have been a part of many environmental programs since the 1960s, including the California Endangered Species Act.
The research team is working on the first studies to look at how tree modification affects carbon storage in the ecosystem.
Wrays and colleagues hope to find ways to manipulate the carbon in tree leaves to increase carbon storage, and find ways of producing plants that do not release carbon dioxide when they are growing.
