资源简介：
The tree is in the early spring growth stage. A small number of leaves have unfolded, but they appear on fewer than three branches and make up less than 5% of the canopy. Yellowish-green catkins are visible, showing early flowering, but pollen is not yet being released on multiple branches. There are no fruits or acorns present, and the tree shows no autumn color change or leaf dropping, confirming that it is not in the fall season.
