An Autonomous Logging Machine Could Make Forestry Safer

Forestry is deadly. Could automating some logging tasks help?

By Susan Cosier

Michael Hall/Getty Images

The first autonomous logging machine rumbled down a Swedish forest path and scanned for stacked logs to transport. It then scooped them up with a crane and loaded them onto its trailer. A new study of the truck-size robot, called a forwarder, suggests it could help forest workers with at least some deadly jobs.

“It’s the first trial for us to see that the machine we built is perhaps capable of doing what we were dreaming it could do,” says Pedro La Hera, a roboticist at the Swedish University of Agricultural Sciences and lead author of the study, published in the Journal of Field Robotics .

Logging jobs are often demanding, requiring operators to multitask and endure nearly constant vibration while operating logging vehicles. Fatigued foresters don’t always pay attention to other foliage in the area, the researchers say, and can damage the ecosystems around them. Logging is also dangerous; in the U.S., it has one of the highest fatality rates of any industry.

Roboticists, software engineers and forestry scholars in Sweden set out to automate some onerous logging tasks. They used GPS to set a path in a clear-cut area and equipped the vehicle with a computer vision system to help it identify, pick up and release cut logs. The predetermined task sequence demonstrates how, in a controlled environment, a machine with little to no human oversight could operate.

“It’s definitely an advancement,” says Thomas Douglass, a logger who owns Thomas Logging and Forestry in Guilford, Maine. “I, along with other contractors in this area, have problems getting help working in the woods, so I can see why at least making the forwarder an automated process would be helpful.”

For now these vehicles’ use may be limited to Sweden, where nearly all forests are managed for commercial logging, paths are well identified, and satellites provide information on logged areas. Loggers in the U.S., in contrast, harvest trees both in plantations and in natural stands where self-piloted machinery would face more challenges.

Still, the research highlights aspects of autonomous machinery that are worth developing further, says Dalia Abbas, a forester who has investigated the effects of logging operations in environmentally sensitive areas. Eventually, Abbas says, she “would definitely hope that it takes into account the fuller range of where it’s operating, whether it includes wildlife, other contaminants or bugs that come with the logs to avoid any infestations, and its sensitivity to the terrain.”

Since the experiments took place, engineers have already improved the machine’s maneuvering capabilities. The researchers are also pursuing other autonomous efforts such as planting seedlings. Although logging may always need human oversight, automating certain steps could make the process safer and more efficient, benefiting both workers and the environment, La Hera says.

The final, formatted version of the article will be published soon.

The impact of climate warming on wetland ecosystem is a current focal point in ecological research. This study chose Napahai wetland, a typical plateau wetland in northwest Yunnan province as study site to understand the growth and survival strategies of emergent plants in plateau wetland under climate warming conditions. Using open-top chambers (OTCs) to simulate warming in three treatment (control group、(2.0±0.5) ℃ and (4.0±0.5) ℃ ), studying the response of functional traits of the dominant emergent plant Schoenoplectus tabernaemontani to simulated warming.The results showed that simulated warming significantly reduced the photosynthetic carbon assimilation capacity and biomass accumulation of Schoenoplectus tabernaemontani, and significantly decreased its nitrogen content and vascular bundle density, while significantly increased the vascular bundle size. Growing season accumulated temperature(AT)and the mean of hottest month(WT) were the main temperature factors influencing the functional traits of Schoenoplectus tabernaemontani. In summary, simulated warming significantly affected the functional traits of Schoenoplectus tabernaemontani, demonstrated its effective adaptation to warming conditions. As the temperature rises and the light and productivity decreases, Schoenoplectus tabernaemontani prioritizes the supply of limited resources to the underground part to ensure the biomass supply of the reproductive structure. This study provides a case for revealing the response patterns and ecological adaptation strategies of plateau wetland plants to climate warming.

Tropical forest landscapes are home to millions of Indigenous peoples and small-scale farmers . Just about every square meter of land is spoken for, even if claims are not formally recognized by governments .

These local landholders hold the key to a valuable solution as the world tries to slow climate change – restoring deforested tropical landscapes for a healthier future.

Tropical forests are vital to Earth’s climate and biodiversity , but a soccer field-size area of mature tropical forest is burned or cut down about every 5 seconds to clear space for crops and cattle today.

While those trees may be lost, the land still has potential. Tropical forests’ combination of year-round sunshine and high rainfall can lead to high growth rates, suggesting that areas where tropical forests once grew could be valuable sites for reforestation . In fact, a host of international agreements and declarations envision just this.

For reforestation projects to make a dent in climate change, however, they have to work with and for the people who live there.

As forest ecologists involved in tropical forest restoration, we have been studying effective ways to compensate people for the ecosystem services flowing from their land. In a new study , we show how compensation that also allows landholders to harvest and sell some of the trees could provide powerful incentives and ultimately benefit everyone.

The extraordinary value of ecosystem services

Tropical forests are celebrated for their extraordinary biodiversity, with their preservation seen as essential for protecting life on Earth . They are reservoirs of vast carbon stocks, slowing down climate change. However, when tropical forests are cleared and burned, they release copious amounts of carbon dioxide , a greenhouse gas that drives climate change.

Programs offering payments for ecosystem services are designed to help keep those forests and other ecosystems healthy by compensating landholders for goods and services produced by nature that are often taken for granted. For example, forests moderate stream flows and reduce flood risks , support bees and other pollinators that benefit neighboring croplands, and help regulate climate .

In recent years, a cottage industry has grown up around paying people to reforest land for the carbon it can hold. It has been driven in part by corporations and other institutions looking for ways to meet their commitments to cut greenhouse gas emissions by paying projects to reduce or prevent emissions elsewhere.

Early iterations of projects that pay landholders for ecosystem services have been criticized for focusing too much on economic efficiency, sometimes at the expense of social and environmental concerns .

Win-win solutions – where environmental and social concerns are both accounted for – may not be the most economically efficient in the short term, but they can lead to longer-term sustainability as participants feel a sense of pride and responsibility for the project’s success.

That longer-term sustainability is essential for trees’ carbon storage, because many decades of growth is required to build up stored carbon and combat climate change.

Why timber can be a triple win

In the study, we looked at ways to maximize all three priorities – environmental, economic and social benefits – in forest restoration, focusing on infertile land.

It may come as a surprise, but most soils in the tropics are extraordinarily infertile , with concentrations of phosphorus and other essential nutrients an order of magnitude or more lower than in crop-producing areas of the northern hemisphere. This makes restoring tropical forests through reforestation more complex than simply planting trees – these areas also require maintenance.

In our study we used some 1.4 million tree measurements taken over 15 years at the Smithsonian Tropical Research Institute ’s Agua Salud site in Panama to project carbon sequestration and potential timber revenues. We looked at naturally regrowing forests, native tree species plantations and an effort to rehabilitate a failed teak plantation by planting high-value native trees known to grow on low-fertility soils to test routes to profitability .

One set of solutions stood out: We found that giving landholders both payments for carbon storage and the ability to generate revenue through timber production on the land could lead to vibrant forests and financial gains for the landholder.

It may seem counterintuitive to suggest timber harvesting when the goal is to restore forests, but allowing landholders to generate timber revenue can give them an incentive to protect and manage planted forests over time.

Regrowing trees on a deforested landscape, whether natural regrowth or plantations, is a net win for climate change, as trees take vast amounts of carbon out of the atmosphere . New forests that are selectively logged or plantations that are harvested in 30 to 80 years can help slow climate change while the world cuts emissions and expands carbon capture technologies.

Reliable payments matter

The structure of the payments is also important. We found that reliable annual carbon payments to rural landlords to regrow forests could match or surpass the income they might otherwise get from clearing land for cattle, thus making the transition to raising trees possible.

When cash payments are based instead on measurements of tree growth, they can vary widely year to year and among planting strategies. With the costs involved, that can stand in the way of effective land management to combat climate change.

Using flat annual payments instead guarantees a stable income and will help encourage more landholders to enroll. We are now using that method in Panama’s Indigenous Ngäbe-Buglé Comarca . The project pays residents to plant and nurture native trees over 20 years.

Shifting risk to buyers of carbon offsets

From a practical perspective, flat annual carbon payments and other cost-sharing strategies to plant trees shift the burden of risk from participants to carbon buyers, often companies in wealthy countries.

The landholders get paid even if actual growth of the trees falls short, and everyone benefits from the ecosystem services provided.

While win-win solutions may not initially appear to be economically efficient, our work helps to illustrate a viable path forward – where environmental, social and economic objectives can be met.

Collection  19 December 2022

Forestry is the combined science and craft behind the plantation, management, restoration, and conservation of forests. From ancient woodlands rich in biodiversity, to intense monocultures for timber production, forests provide vital resources and ecosystem services for wildlife and people alike. Climate change, increased human pressures, and loss of biodiversity have led to a growing interest in active and sustainable forestry practices. Recent years have seen a push for the preservation of natural forests and plantation of new woodland areas, alongside better agricultural, industrial, and urban standards.

This Collection welcomes submissions from all fields of modern forestry and interdisciplinary research, providing new insights into sustainable forest creation, management, and conservation.

Research: Negotiating Is Unlikely to Jeopardize Your Job Offer

• Einav Hart,
• Julia Bear,
• Zhiying (Bella) Ren

A series of seven studies found that candidates have more power than they assume.

Job seekers worry about negotiating an offer for many reasons, including the worst-case scenario that the offer will be rescinded. Across a series of seven studies, researchers found that these fears are consistently exaggerated: Candidates think they are much more likely to jeopardize a deal than managers report they are. This fear can lead candidates to avoid negotiating altogether. The authors explore two reasons driving this fear and offer research-backed advice on how anxious candidates can approach job negotiations.

Imagine that you just received a job offer for a position you are excited about. Now what? You might consider negotiating for a higher salary, job flexibility, or other benefits , but you’re apprehensive. You can’t help thinking: What if I don’t get what I ask for? Or, in the worst-case scenario, what if the hiring manager decides to withdraw the offer?
