Shortleaf pine seedling production and seeding trends in Missouri (2007)Gwaze, D., Hoss, G., & Biram, D. (2007). Shortleaf pine seedling production and seeding trends in Missouri.

Seedlings and seed have been sold to landowners since 1935. Prior to 1981 most seed was locally collected wild seed, some was purchased from neighboring states. After 1981, most of the seed for artificial regeneration was improved orchard seed. The highest production of shortleaf pine seedlings occurred prior to 1987 with at least 2 million seedlings being produced annually. Today less than half a million seedlings are produced at the nursery. Before 1990 most of the seedlings were delivered to the Mark Twain National Forest, but now it is a minor player in artificial regeneration of shortleaf pine. Trends in seed distributed for direct seeding followed those of seedling production. This paper discusses factors that influenced the trends in shortleaf pine seed distribution and seedling production, and makes suggestions for future direction
