Question

Q1) Based on the information in the unit, explain why the number of predators is declining in the

Appalachian region. What effects might this have on the forest?


Q2) Why is it important that diverse areas of the forest are monitored when counting trees? What
could happen if this wasn't done?

Q3) The unit discusses measuring growth in forests. Where else might it be important to measure
the growth of trees? Why?

Q4) If trees in a timber cruise were found to be of many different species, would that mean that the
forest could be used for timber? Explain your answer.

Q5) Why do you think that biodiversity is good for ecosystems?

Answer 1

Q1) The number of predators is declining in the Appalachian region due to factors such as habitat loss, hunting, and disease. This can have significant effects on the forest ecosystem, as the absence of predators can lead to an increase in the populations of their prey. This can, in turn, cause a decrease in the populations of other species that rely on those prey for food, and can also result in an overgrazing of certain plant species, leading to a disruption in the balance of the forest ecosystem.

Q2) It is important to monitor diverse areas of the forest when counting trees because different areas may have different types of trees or different densities of trees. Focusing on only one type of area or tree species could result in an inaccurate count and misrepresentation of the forest's overall health. If diverse areas of the forest are not monitored, it could lead to an incomplete understanding of the forest's ecosystem, and potentially lead to poor management decisions.

Q3) It is important to measure the growth of trees in other areas such as urban environments, parks, and nature reserves. This is because trees provide essential benefits such as shade, air purification, and carbon sequestration, and monitoring their growth can help determine their health and inform management decisions. In urban environments, for example, trees can help mitigate the effects of heat islands and improve air quality.

Q4) The presence of multiple species in a timber cruise does not necessarily mean that the forest can be used for timber. The species of trees, their size, and their density all play a role in determining the economic viability of a timber harvest. Additionally, other factors such as the terrain and accessibility of the forest also need to be considered.

Q5) Biodiversity is important for ecosystems because it provides stability and resilience. A diverse ecosystem can better withstand environmental stressors such as climate change, disease, and natural disasters, as different species may have different adaptations and roles within the ecosystem. Biodiversity can also provide important ecosystem services such as pollination, nutrient cycling, and pest control. Furthermore, a diverse ecosystem can be more aesthetically pleasing and provide recreational opportunities for people.
