\section{Study design}

\begin{frame}{Study design}
  \begin{itemize}
    \item 48 one-hectare plots across three concessions, logged between 2008 and 2015.
    \item Annual airborne lidar from 2016 to 2025 paired with ground inventories.
    \item Matched unlogged control plots within 2 km of each treatment plot.
    \item Mixed-effects models of canopy height with plot and year random effects.
  \end{itemize}

\section{Key findings}

    \begin{tabular}{lrr}
      \toprule
      Harvest intensity & Height recovery at 10 yr & Gap fraction \\
      \midrule
      Low (2 trees/ha) & 92\% & 4.1\% \\
      Medium (5 trees/ha) & 78\% & 7.9\% \\
      High (8 trees/ha) & 61\% & 13.6\% \\
      \bottomrule
    \end{tabular}
  \end{table}
  \vspace{0.5em}
  Recovery slows sharply above 5 trees per hectare, and skid trail layout
  explains more variance than harvest volume alone.
