Some trees are better at surviving drought, fire, pests, and diseases than others. By identifying the genes responsible for these adaptations, scientists can compile a scalable database that will aid resource managers as they plan long-term conservation strategies, particularly as the climate changes.
UC Davis, Johns Hopkins University and Save the Redwoods League are working together to protect this iconic tree.
Professor David Neale, UC Davis Department of Plant Sciences, showed in preliminary research that it is feasible to sequence the redwood, which has a genome 10 times larger than ours. Redwoods are “hexaploid” with six copies of each chromosome compared to humans’ two copies.
Under certain conditions, forests can grow in response to climate change

After a tip-off from nomadic herders, a team of scientists has confirmed reports of a forest expansion in eastern Tibet, a region dominated by ancient grasslands. The forest growth, unprecedented since 1760, is due to a combination of climatic changes: rising atmospheric carbon dioxide, increased water related to warming, and greater nutrient availability released by thawing permafrost.
