There’s a growing demand for timber in the U.S. — and grazing landowners may be able to take advantage of this opportunity — with a little foresight and planning.

The concept of silvopasture is gaining more and more traction in the South, where managing acres for timber, nuts or fruit production is routine. Rocky Lemus, Mississippi State University Extension plant and soil sciences expert, explains that integrating livestock into a forest stand that is being managed for timber production or pecan production means a farmer can get a yearly return while they’re waiting for that forest to mature. Lemus spoke at the 2023 Cattlemen’s College in New Orleans in February.

Why trees?

According to Justin Baker, North Carolina State University associate professor of forestry and environmental resources, there is a growing demand for timber products from the construction and energy sectors, of course. But now there are carbon price incentives on the table to grow more forests and increase the global forest carbon sink.

From their modeling, “Low greenhouse gas emissions, high demand for wood products and government policies that paid landowners high prices for storing carbon in their trees drove gains in the amount of land area devoted to forest,” according to NCSU.

Adding trees to grazing lands sounds great in theory, of course. But there are a lot of moving parts to the complex silvopasture system, Lemus warns.

He says you’re not just managing the grassland in a silvopasture — you’re managing the trees for their end harvest, accounting for animal production goals and improving wildlife habitat. All of this changes depending on your soil type, and what trees and forages grow best in your region.

“Know why you want to do this,” he advises. Do you want to manage for peak animal performance and consider the timber as a side benefit? Do you want to provide wildlife habitat for a side hunting enterprise? Or, are you considering the trees as a lucrative cash crop, in the case of pecan or other nut-bearing trees?

Get started

In a silvopasture system, you can either introduce trees into your pasture system, or you can introduce forages into a thinned forest stand. In the south, Lemus explained, it’s more common for cattle producers to introduce forages into established timber. The first critical step is to work with a forestry expert or logger who understands your goals.

The key is to manage the canopy so that enough sunlight reaches the floor to grow your forage, while accounting for valuable mature trees. That may mean thinning existing stands. Or, if you’re planting trees, planting them with enough room between to be able to drive equipment and implements through, Lemus said.

Lemus said the next step is to consider what forages you want to establish and to make sure you apply enough soil amendments to combat acidic soils, especially if you choose legumes as your forage.

“If you’re going into areas with a lot of brush, maybe use a small ruminant to clean up the area before you start your forage production,” Lemus said.

If you are planting trees and planning to graze livestock at the same time, you’re going to need to plan to protect those saplings from the livestock, he added.

“Livestock will tend to eat trees, and clip that terminal bud at the top,” Lemus warned. So, either purchase more mature saplings, plan to fence them off from grazing livestock, or just manage that pasture for hay production until they are more mature.

Forage selection

When you’re choosing your forage species, you need to consider those that are matched to your climate, of course — but you also need a forage that does well in shade and will meet the nutritional needs of your livestock, Lemus said.

“In the south we can use Bahia grass, bermudagrass and Dallis grass,” he said. “Bahia grass is especially shade-tolerant.” The farther north into the transition zone, he says orchardgrass, tall fescue and other cool-season grasses work well under 50% shade.

Small grains like ryegrass, cereal rye, triticale, oats and wheat are another option for grazing, he said.

Cattle producers might prefer to plant legumes; or white clover, red clover and alfalfa work well in the silvopasture system. Just remember to select a legume that tolerates shade and acidic soils.

Tree selection

Lemus advised matching your tree selection to your zone, and making sure you purchase large, healthy seedlings grown locally from an adapted seed source.

In the South, they can grow loblolly pine, pecan and longleaf. In the transition zone, honey locust, willow or poplar are ideal, depending on your location.

As you plan your system, you need to leave enough space for the forest to grow, and for equipment like balers and manure spreaders to maneuver. “We recommend you target a tree density of no more than 200 trees per acre, with a forage lane of 30 to 40 feet wide,” he said.

Livestock benefits

You can run cattle, sheep, goats, or a mix of livestock in a silvopasture, Lemus said. The livestock will provide you with diversification of income until that timber is matured. But the timber also provides shade and windbreaks for livestock, which improves their performance. They’ve seen weight gain by as much as 10% in a silvopasture system, while reducing their supplemental feed by 50%. And in the case of dairy cattle, milk production increased by 8% to 20%.

“Windbreaks reduce or eliminate the loss of newborns from windchills,” Lemus said.

And the reduced evapotranspiration from the shade actually lengthens the feed production cycle, Lemus said. A Virginia Tech study showed silvopastures can grow up to 55% more forage. When managed for livestock production, they can be 42% more productive.

Overall, Lemus advised patience, flexibility, and to start small and be willing to adapt as you plan your silvopasture for the long term.

Through all her travels, Jennifer M. Latzke knows that there is no place like Kansas.

Jennifer grew up on her family’s multigenerational registered Angus seedstock ranch and diversified farm just north of Woodbine, Kan., about 30 minutes south of Junction City on the edge of the Kansas Flint Hills. Rock Springs Ranch State 4-H Center was in her family’s backyard.

While at Kansas State University, Jennifer was a member of the Sigma Kappa Sorority and a national officer for the Agricultural Communicators of Tomorrow. She graduated in May 2000 with a bachelor’s degree in agricultural communications and a minor in animal science. In August 2000 Jennifer started her 20-year agricultural writing career in Dodge City, Kan., on the far southwest corner of the state.

She’s traveled across the U.S. writing on wheat, sorghum, corn, cotton, dairy and beef stories as well as breaking news and policy at the local, state and national levels. Latzke has traveled across Mexico and South America with the U.S. Wheat Associates and toured Vietnam as a member of KARL Class X. She’s traveled to Argentina as one of 10 IFAJ-Alltech Young Leaders in Agricultural Journalism. And she was part of a delegation of AAEA: The Ag Communicators Network members invited to Cuba.

Jennifer’s an award-winning writer, columnist, and podcaster, recognized by the Kansas Professional Communicators, Kansas Press Association, the National Federation of Presswomen, Livestock Publications Council, and AAEA. In 2019, Jennifer reached the pinnacle of achievements, earning the title of “Writer of Merit” from AAEA.

Trips and accolades are lovely, but Jennifer says she is happiest on the road talking to farmers and ranchers and gathering stories and photos to share with readers.

“It’s an honor and a great responsibility to be able to tell someone’s story and bring them recognition for their work on the land,” Jennifer says. “But my role is also evolving to help our more urban neighbors understand the issues our Kansas farmers face in bringing the food and fiber to their store shelves.”

She spends her time gardening, crafting, watching K-State football, and cheering on her nephews and niece in their 4-H projects. She can be found on Twitter at @Latzke.
