Native know-how

Cuivre Island off the Mississippi River was once full of soybeans. Now it’s home to more than a dozen species of native trees from Forrest Keeling Nursery. The site boasts a more than 95 percent survival rate.Photo by Bill sawalich, Barlow productionsNative species are long-lived and durable—traits Wayne Lovelace and Kim Lovelace-Young require from their plant material and their business, Forrest Keeling Nursery in Elsberry, Mo. The father-and-daughter team recognized the potential of the native market years ago, and now that sector makes up more than half the nursery’s total annual volume.

“We saw an opportunity to grow natives, especially ones being used in the environmental field,” said Wayne, owner of Forrest Keeling Nursery (FKN). “We specialize in native oaks and members of the hickory family. There are 21 varieties of oaks native to Missouri, and we grow them all.”

FKN grows 250 varieties of native species for restoration and conservation projects, for specimen tree growers and for retail garden centers. Many of the nursery’s seedlings are planted in wetland restoration and reforestation projects.

“The restoration market has held up well during the last few years, in part because many of these projects are funded far in advance and they maintain themselves,” Wayne said.

Thousands of trees from FKN are now in their 14th year at Cuivre Island Conservation Area, a bottomland forest restoration project near St. Louis along the Mississippi River. The project’s goal was to establish hard mast trees, such as oaks and pecans, said Kim, vice president and general manager at FKN. Prior to the planting, the site had been in soybeans for 40 years, she said. Some of the species planted at the island include swamp white oak (Quercus bicolor), pin oak (Q. palustris), nuttall oak (Q. texana), native pecan (Carya illinoensis) and Kentucky coffeetree (Gymnocladus diocus).

The site has flooded every spring except for three years since installation and experienced prolonged inundation during the flood of 2008. The survival rate of the FKN trees is 95 percent, Kim said. She attributes the transplant success to the nursery’s Root Production Method (RPM), a system Wayne developed and patented.


A system for survival
Kim Lovelace-Young said she still learns something new every day from her father Wayne Lovelace. They get a lot of satisfaction from providing a product for restoration projects and being able to see the results.
RPM is a system that starts with a superior seed, Wayne said.

“We select the heaviest seed. The size of an acorn is not that important. It’s the density or weight,” he said.

Seeds are germinated on raised beds at different depths. The depths vary, and the depth details are proprietary. At the first stage of germination, all seedlings are graded where up to 40 percent of the seedlings are discarded. Seedlings are shifted up and air pruned, then planted into a squat container designed by FKN. The process is used for trees, shrubs, grasses and perennials.
