In the novel entering the forest "Entering the Forest", the two main characters, Nell and Eva live together. They grew up at the same place away from the same parent, but they formed a unique personality and a view of life. In the early stages of the novel, there are two small things that are different from the two girls. For example, Nell wants to save, save and save things, Eva is ready to use something to accomplish something.
Collecting data on forest health is an amazingly big job. ForestGEO monitors 65 forests in 28 countries, of which more than 6 million forests represent about 10,000 species, each forest monitoring plot ranges from 50 acres to 100 acres. In each figure, scientists physically interact with each tree. "It requires a lot of work and forestry and botany skills," Anderson-Teixeira says. "In each plot, each tree that exceeds 1 centimeter in diameter (finger size) is drawn on the grid, identified, measured, given a permanent marker, usually re-examined every 5 years "
ForestGEO was a grass-roots association of scientists who were originally interested in the health of the forest. Today it is the only research forest network that standardizes these protocols in all kinds of forests around the world. "This makes us a unique position to compare.We are studying larger plots and smaller tree sizes than most typical forest plots.The data and types of problems we can ask for Anderson - Tesila said they are learning about the poor health patterns that are beginning to emerge in the world's forests because they experience drought, wildfires, permafrost melting, diseases and pests And it is a product of climate change or aggravating factors.However they also show that some species and some forests are more resistant to these changes than others I saw a certain thing.
Due to similar soil, moisture, climate, topography and past history, certain species of forests grow together. These tree species communities are called forest types and can be divided into forest type groups. Broadleaf forest types (hardwood deciduous species such as oak, poplar and maple) are the most common in Michigan forests. They account for about 75% of the forest area. The rest is a group of cork forest types (consisting of pine, spruce, cedar tree). The two largest forest type groups in Michigan State are Maple Eucalyptus (commonly known as Northern Hardwood), with an area of 6.7 million acres and a White Ash Birch area of 3.4 million acres (Figure 2).
