What contributes to the huge increase in the pine tree's biomass?

The significant increase in pine tree biomass can be attributed to factors such as optimal growing conditions, including adequate sunlight, water, and nutrient availability. Additionally, advancements in forest management practices, selective breeding for faster-growing varieties, and the reduction of pests and diseases through improved forest health measures have all contributed to enhanced growth rates. Climate change may also play a role, as rising temperatures and increased carbon dioxide levels can accelerate photosynthesis and growth in certain pine species.
