I'm assuming you are asking how long it will take a forest to grow back from destruction, and by first stage I'm assuming there is already saplings planted. It takes the trees up to five years to reach the second stage, established growth, and up to 50 years for the trees to fully mature. For the forest to reach its original state, however, it can take hundreds of years for everything to grow back and the trees to be as massive.
Old growth forest
This kind of weed growth actually represents secondary succession.
The stage of succession that supports the growth of trees is the mid-succession stage. In this stage, the soil has developed enough nutrients and organic matter to support the growth of taller plants, such as shrubs and small trees. These early trees help create shade, retain moisture in the soil, and provide habitats for other plant and animal species.
The other name for the first growth phase is called the G1 phase.
Products in the growth stage could be Plasma TVs or Net PCs.Samuel us currently in its growth stage.

Growth
Hair growth occurs in three main stages: anagen (active growth phase lasting 2-7 years), catagen (transitional phase lasting 2-3 weeks), and telogen (resting phase lasting 2-4 months). During anagen, the hair follicles are actively producing hair; in catagen, hair growth stops and the follicles shrink; and in telogen, old hairs are shed to make way for new growth.
Growth stage
Organisms show the most growth during the first stage of their life. During this time the cells are changing and coming together.
Go through the forest and on the left side in the middle of the forest is a tube that takes you to the first stage in bubble lake.
There are three stages in the annealing process. The first stage is when a metal is heated up and it is called the recovery stage. The second stage is called recrystallization and the third stage is called gain growth. Each stage represents a higher temperature in the annealing process.
