Drivers of natural regeneration seedling dynamics in a Larix gmelinii var. principis-rupprechtii artificial forest.

ABSTRACT: Seedling dynamics are crucial for forest regeneration and species coexistence. Understanding the factors influencing seedling survival rate provides insights into improving natural regeneration. This study evaluated the effects of biotic and habitat factors on Larix gmelinii var. principis-rupprechtii seedling survival rate over 2 years on Guandi Mountain, North China, using a generalized linear mixed-effects model. Our results did not provide strong evidence of negative density dependence at the community level during the seedling stage. For seedlings < 2 cm in diameter and < 8 years old, survival rate was primarily influenced by conspecific seedling density. As seedlings grew, the impact of biotic factors declined, whereas soil and light conditions became more important. Elevation strong
