Table 3 Literature that discussed the influence of various climate metrics on tree regeneration following wildfires. Study, region, significant climate metric evaluated, the time period over which climate was considered, and the relationship of said climate variable and tree regeneration along with additional information on major findings. A plus sign (+) indicates a positive relationship between climate metric and tree regeneration, a minus sign (−) indicates a negative relationship, and a zero (0) indicates no relationship. Specific species-level information is described when individual papers analyzed climate variables against individual species
