Post-fire resprouting capacity of seasonally dry forest species: two quantitative indices

The study introduces two quantitative indices, RCI 1 (ECRD/ECTD) and RCI 2 (MRD/MTD), to assess post-fire resprouting capacity in the arid Chaco of Argentina. Testing 1,046 plants across 20 species, the researchers found that both indices correlate strongly with resprouting vigour and provide more detail than survival-only assessments. Results indicate that resprouting capacity decreases as the estimated composite diameter of trunks (ECTD) increases, and that growth form influences RCI 2 values, with tree/shrubs and trees generally showing higher RCI 1 values than shrubs.

• The study proposes two quantitative Resprouting Capacity Indices: RCI 1, calculated as the ratio of estimated composite diameter of resprouts to trunks (ECRD/ECTD), and RCI 2, calculated as the ratio of main resprout diameter to main burned trunk diameter (MRD/MTD).
• Both proposed indices (RCI 1 and RCI 2) showed a high relationship with Resprouting Vigour (RV) at both the species and growth form levels, and this relationship was not significantly affected by fire severity.
• Analysis of 20 dominant species revealed that all were capable of resprouting, though capacity varied by species and size; specifically, resprouting capacity decreased as the estimated composite diameter of trunks (ECTD) increased.
