This month USDA will be highlighting the value of conservation with a different focus each week.
Sometimes the benefits of conservation can be abstract. For example, think a minute about the dollar value of a single tree. Can you come up with a number?
Did you consider that the tree creates oxygen, captures carbon and provides wildlife habitat? Or that the tree serves as a windbreak, shades and cools the surrounding area, and improves water quality? Don’t forget, these benefits extend for many decades over the lifetime of a healthy tree.

With yet another busy fire season around the corner, the U.S. Forest Service, CAL FIRE and the U.S. Fire Administration decided to take to social media and talk about America’s PrepareAthon!, which is a nationwide, community-based campaign for action to increase emergency preparedness and resilience through hazard-specific drills, group discussions and exercises conducted at the national level every fall and spring. Wildfire experts will be ready to answer any questions that range from how to help protect your home from wildfire to what the wildfire season forecast looks like this year.
Drought conditions in the West, especially in California, combined with other factors portend a dangerous fire season that now could start at any time. Last year, 34 wildland firefighters died in the line of duty as fire ravaged 4.1 million acres and destroyed more than 1,000 homes around the Nation. This year the U.S. Forest Service has more than 10,000 firefighters who stand ready as well as aircraft and engines deployed around the country. Should that call be received, these firefighters and the tools that they use are ready to spring into action. Read more »
The U.S. Forest Service has burned more than 480 acres in the Flying J Project, an effort on the Kaibab National Forest in Arizona to protect the community of Tusayan. The project is outside the Grand Canyon National Park and represents a small part of a larger effort to use controlled burns on more than 4,500 acres of the forest. So far, nearly 1,900 acres have been treated. (U.S. Forest Service/Holly Krake)
The loss of property and firefighters during wildfires are a reminder of the challenges we face in reducing the risks associated with large, unpredictable wildfires. Climate change, drought, insect infestations, changing land-use patterns, and other factors have contributed to increases in the complexity and in the numbers of wildfires across the United States.
Over the past four decades, some states such as Arizona and Idaho have seen the number of large fires burning each year more than triple. In many other western states, including California, Colorado, New Mexico, Nevada, and Wyoming, the number of large fires has doubled, according to a report by Climate Central. Average spring and summer temperatures across 11 Western states have increased by more than 1.5 degrees Fahrenheit, contributing to higher wildfire risks. In Arizona, spring temperatures have warmed faster than any other state in the U.S., rising nearly 1 degree per decade since 1970, which likely played a role in the increasing number of fires in the state.

Those of us living and working in the Southwestern U.S. have recently experienced a prolonged, extreme drought persisting over several years. We have witnessed large, destructive and catastrophic wildfires that have taken both lives and property, observed expansive areas of forest tree death as a result of massive insect outbreaks, and seen our water supplies in reservoirs and dams across the region decline to previously unseen levels. Yet, what can we realistically do in the face of these climatically driven changes that will likely continue and intensify into the future?
Changing climatic conditions in the southwest that impact temperatures, alter growing seasons, increase plant moisture stress, and trigger extreme events directly contribute to these recent regional catastrophes and water scarcities. Recently, a highly respected, third generation public land cattle rancher in our region put it this way: “I believe that the climate is changing. But I can’t accept it. If I do I would just go out of business. I have to cope and go on.” So we are left to look around us and ask what information, tools, and technology can we reach for when it gets tough? Read more »

During World War II, a time when segregation was still a part of everyday life, a group of 17 brave men took the plunge to serve their country and become the first all African-American paratrooper unit known as the Triple Nickles.
The battalion’s original goal – to join the fight in Europe – was thwarted when military leaders in Europe feared racial tensions would disrupt operations. At about the same time, the U.S. Forest Service asked the military for help to minimize damage caused by balloon bombs launched by the Japanese across the Pacific Ocean with the intent to start forest fires in the western U.S. during World War II.
In the end, few of the incendiary devices reached U.S. soil, but the Triple Nickles were instrumental in helping the Forest Service fight naturally-caused fires. They became history’s first military smokejumpers who answered 36 fire calls and made more than 1,200 jumps that summer of 1945. Read more »

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from USDA’s rich science and research portfolio.
An award-winning watershed assessment tool, the Automated Geospatial Watershed Assessment (AGWA), was deployed to assess potential Rim Fire threats in Yosemite National Park in California. The park experienced a devastating fire that began on August 17, 2013, and took several months to contain. The fire burned more than 400 square miles in and around the park, cost $125.8 million to date, and is considered one of the largest wildfires in California’s history.
BAER (Burned Area Emergency Response) is a multi-agency group that includes USDA’s Forest Service and others, and is responsible for identifying potential threats such as downstream flooding and developing plans to rehabilitate and restore burned areas. BAER teams use AGWA to target immediate efforts to prevent threats to people, wildlife and the land. Using AGWA combined with the burn severity map produced by BAER teams, experts can rapidly pull together information on pre- and post-fire conditions. For example, knowing where to apply mulch after a fire can reduce runoff and erosion and can help minimize downstream risks from fire induced land cover and soil changes. Read more »
