It can reach heights of 200 feet and live 500 years, and occupies landscapes across the western United States. Some say its bark has an unforgettable smell resembling vanilla or even cinnamon, and this tree is one tough cookie. It grows in a variety of soils and climates and survives fires that consume other species. It is also an ecologically and economically valuable tree that provides food, habitat and ponderous (heavy) lumber.
It is the iconic ponderosa pine. But the world is changing, and ponderosa pine is vulnerable to climate shifts, high-intensity wildfires and bark beetles — as well as development that replaces trees. To keep the ponderosa pine standing tall, researchers are looking for answers in its genes. Read more »
People who suffer from peanut and wheat allergies may soon find relief thanks to USDA funded research.
The release of the USDA’s 2014 Technology Transfer Report highlights the groundbreaking discoveries made by USDA researchers, who continue to push the envelope and come up with new and exciting innovations. The scientific advancements in knowledge and the creation of new technologies directly impact Americans in that they create safer environments and provide efficient solutions for a wide range of issues. Here are just four of the transformative innovations that can be found in the USDA Tech Transfer Report: Read more »

This year I have had the pleasure of visiting a number of urban agriculture operations. From California to Cleveland, the ability of individuals to realize the multidimensional benefits of agricultural production and leverage them in an urban context has been nothing short of amazing.
This past week I visited a University that is heavily involved in both the research and extension aspect of urban agriculture — right in the backyard of the Department’s Washington, D.C. headquarters. The University of the District of Columbia’s (UDC) Muirkirk Agricultural Experimentation is located about 20 minutes north of the school’s D.C. campus. Upon arrival I found everything from activists passionate about learning how to best provide their neighbors with fresh produce, to researchers developing improved hydroponics systems; and even students working with community organizations on rice varieties suitable to be grown in urban areas.

On June 9, 2012, a lightning strike sparked a wildfire in the mountains west of Fort Collins, Colorado, burning into the Roosevelt National Forest. The High Park fire burned over 87,000 acres and remains the third largest fire in recorded Colorado history, with more than 250 homes destroyed.
Matt Champa, assistant prescribed fire specialist with the Canyon Lakes Ranger District of the Arapaho and Roosevelt National Forests, remembers clearly the two and a half weeks the High Park Fire burned. Matt was among the individuals actively working on the ground to suppress and contain the fire; at its height, more than 2,000 people were involved in the suppression effort. Read more »
As an ecosystem ecologist working for the U.S. Department of Agriculture, pollinators are near and dear to me. Not only are they vital to agricultural production, providing billions of dollars in pollination services for the fruits, nuts and vegetables that contribute to a healthy diet, they are also important members of natural ecosystems, pollinating the plants that many other organisms rely on for food and habitat. Yet pollinators have been having a rocky time, lately. Beekeepers have struggled to maintain their honey bee colonies, the primary pollinators for our crops in the United States. They are managing a suite of simultaneous and interacting stressors to bee health, including severe weather episodes, inadequate nutrition, exposure to pesticides, and numerous damaging pests and diseases. Native pollinators also seem to be struggling with some of these same stressors, as well as land use change and habitat loss. Because of the incredible diversity of native pollinators, we know much less about their individual populations and the factors affecting their health. Read more »

The U.S. Geological Survey estimates that several million earthquakes occur in the world each year. Some, such as the devastating earthquake in Nepal and the series of earthquakes that destroyed infrastructure, homes and communities in Christchurch, New Zealand in 2011, capture global attention.
After natural disasters such as these, rebuilding a city needs to be efficient and cost-effective, with an eye towards resilience in the face of future disasters. Engineered wood building systems like glulam and cross laminated timber, also known as CLT, are well suited to meet these needs as they are often prefabricated offsite and can be quickly installed. That helps communities bounce back from disaster in a shorter time frame while minimizing waste. Furthermore, just as trees flex in high winds, timber structures flex in earthquakes, placing wood construction systems at the forefront of seismic design for resilience. Read more »
