Characterizing the growth of Pinus palustris and the relationship with cone production at the individual tree level

Dendrobiology
Regenerating longleaf pine (LP) (Pinus palustris Mill.) is essential for sustaining the production of high-value wood products and ecological benefits. Understanding the relationship between LP growth and cone production is critical for this effort, as both processes contribute to natural regeneration.
