Producing new varieties of trees can be challenging due to their long generation times, which can take several years or even decades to produce viable offspring. Additionally, trees often have complex genetics, making it difficult to predict and manipulate traits in breeding programs. Furthermore, ensuring the new tree variety has desired characteristics, such as disease resistance or improved growth, requires extensive testing and evaluation before it can be released to the market.

The produce seeds so tht new pine trees can be born.
There is no exact number. The reason behind this is each year there is always new hybrid trees being grown.

Producing new varieties is important to keep up with changing consumer preferences, increase crop productivity, enhance disease and pest resistance, and adapt to evolving environmental conditions such as climate change. Developing new varieties can also help improve food security by providing farmers with more sustainable and resilient options.
In the spring, trees start to grow new leaves as the weather becomes warmer and the days get longer. This process is called leaf-out, and it helps the trees photosynthesize and produce energy. Additionally, in the spring, some trees may also start to bloom and produce flowers for reproduction.
By using vegetative propogation i.e. cuttings you will produce a clone of the parent.
Redwood trees often grow in a circle due to a phenomenon known as "clone" growth. When a mature redwood tree falls or is damaged, its root system can produce new shoots, which grow into new trees. Over time, these new trees form a circular pattern around the original tree, creating a "fairy ring" effect. This formation helps the trees share resources and thrive in their environment.
