…the Volkswagen beetle that is. You might have if you were in Ohio the last few weeks. 

As part of the efforts to raise awareness about the invasive Asian longhorned beetle (ALB), a non-native insect originating from Asia that is attacking and killing out native U.S. trees, the USDA’s Animal and Plant Health Inspection Service (APHIS) wrapped a Volkswagen beetle to look like Asian longhorned beetle.  The moving advertisement was part of a campaign meant to help inform residents about the beetle infestation in Ohio.

Living memorials serve as a reminder of fathers and mothers, sons and daughters, brothers and sisters, neighbors and friends—but also of the power of community to reflect, rebuild and renew. Our research suggests that living memorials demonstrate the role of nature in contemporary times not only as a symbol, but as an innate and purposeful response to loss that calls forth a common humanity and compassion for others.

In other words, they demonstrate how people use nature to be resilient to loss.

Standing in a disturbed patch of forest, Menominee forester Jeff Grignon looks around and explains, “My role is to regenerate the forest, maintain the forest, create diversity, and look toward the future.” This task is becoming increasingly challenging as growing forest health issues intersect with additional stressors brought about by climate change in the forests of the Menominee Nation and elsewhere.

As a leader in forestry and natural resource conservation, USDA has a long history of working with tribes to address their management issues and concerns. Climate change is an active part of that discussion, and has been increasing through development of the new USDA Regional Climate Hubs. The network of Hubs deliver science-based knowledge, practical information, and program support to help natural resource managers, producers, and landowners make climate-informed decisions and then implement those decisions.

Do you have a citrus tree in your backyard? From afar it may look fine, but when was the last time you took a close look? Your tree could be hiding all kinds of clues about its health. Here are a few resources to hone your citrus sleuth skills!

Checking your citrus tree regularly is extremely important to prevent the spread of citrus disease. Four serious citrus diseases found in the United States include: Huanglongbing (also known as citrus greening or HLB for short), citrus canker, citrus black spot and sweet orange scab. These diseases are a threat to the health of U.S. citrus, and finding them early is critical. That’s why we need your help!

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.

Bountiful harvests don’t magically appear on store shelves and supermarkets. USDA scientists strive to make sure that the variety of meats, fruits, vegetables and grains we enjoy are hardy enough to withstand insects, diseases, droughts and other natural threats familiar to anyone with a garden or farm.

David Fairchild, a USDA scientist, was a key part of that effort. Fairchild collected plants from all over the world so they could be studied and bred. He organized the USDA's Office of Foreign Seed and Plant Introduction and served as its chairman for more than 20 years. He is credited with introducing about 30,000 plant species and variations into the United States, and he was instrumental in establishing gardens throughout the United States to screen plants with potential for improving our diets, gardens and landscapes.

Following a wildfire, some might see dead trees. Woodpeckers see possibilities.

The black-backed woodpecker is one such bird—a burned forest specialist—who readily chooses fire-killed trees (snags) in which to drill cavities for nesting and roosting.

When the woodpecker moves on, its cavity turns into valuable habitat for other forest-dwelling species.

Do you grow fruits and vegetables in your backyard or community garden? Do some of them come from trees?

Breadfruit, or ‘ulu, is an easy-to-grow, productive, nutritious, and starchy staple crop grown in many Pacific Islands, including Hawaii. It can be roasted, baked, boiled, fried or pounded into poi. In the past, many people grew breadfruit at home and in community gardens. However, many breadfruit trees have been cut down, especially in urban areas. Products such as breadfruit can have a helpful impact on Pacific islands such as Hawaii, imports about 85 percent of its food.

Trees killed by bark beetles have, for years, been a source of fuel for forest fires.  Now, those very trees are being turned into biofuel and biobased products.

This vast bioenergy resource—approximately 46 million acres—requires no cultivation, circumvents food-versus-fuel concerns, and may have a highly favorable carbon balance compared other forestry feedstocks. The problem, however, is that beetle-killed biomass is typically located far from urban industrial centers in relatively inaccessible areas, which means transportation costs are a key barrier to widespread utilization of this vast resource.

We can achieve more when we voluntarily work together, and the decision today not to list the Bi-State sage-grouse under the Endangered Species Act proves the power of partnerships. In this case, collectively, we were able to proactively conserve and restore habitat for this geographically distinct sage-grouse.

USDA’s Natural Resources Conservation Service works with conservation partners and ranchers in Nevada and California to take steps to benefit sage-grouse habitat while also helping ranchers improve their ranching operations. Meanwhile, this work helps connect public lands like national forests, where U.S. Forest Service is working to restore habitat, too.
