Shortleaf pine reproduction abundance and growth in pine-oak stands in the Missouri Ozarks (2007)Blizzard, E. M., Henken, D., Kabrick, J. M., Dey, D. C., Larsen, D. R., & Gwaze, D. (2007). Shortleaf pine reproduction abundance and growth in pine-oak stands in the Missouri Ozarks. Northern Research Station, General Technical Report NRS-P-15. Retrieved from http://www.fs.fed.us/nrs/pubs/gtr/gtr_nrs-P-15.pdf#page=145 We conducted an operational study to evaluate effect of site preparation treatments on pine reproduction density and the impact of overstory basal area and understory density on pine reproduction height and basal diameter in pine-oak stands in the Missouri Ozarks. Stands were harvested to or below B-level stocking, but patchiness of the oak decline lead to some plots having no overstory and some having over 200 ft2 /ac basal area at the end of the study. In all stands, the midstory and understory were chainsaw felled. If stands were inadequately stocked with pine reproduction, then mechanical scarifying or prescribed burning treatments were applied to increase the density of shortleaf pine reproduction. Pine reproduction basal diameter, height, and crown class within the understory were measured three to eight growing seasons later
