Fig. 7From: Modeling spatial patterns of longleaf pine needle dispersal using long-term dataComparison of regressions for predicted needle litterfall vs. observed litterfall of the external validation data. Observed data are of three different longleaf pine forest sites varying along an edaphic gradient (xeric, intermediate, and mesic) in southwestern Georgia, USA from years 2019–2021.
