Trees in tropical deciduous forests lose their leaves in the dry season and regrow them in the rainy season. In temperate deciduous forests, trees lose their leaves in the fall and regrow them in the spring.During the dry season in a deciduous forest, trees shed their leaves to conserve water, they do not die off, but rather become dormant and regrow new foliage during the next suitable growing season.  the forest canopy becomes less dense,the plants under the canopy may experience increased sunlight exposure, and the ground becomes drier and potentially more susceptible to wildfires.
