What is a common guideline to aim for to maintain species diversity in an urban forest?

1. Composting

2. Economic, environmental, social

3. The process of decomposition of organic matter by microorganisms

4. What 4 types of data are typically collected in a tree inventory?

The correct answer is: Composting

Maintaining species diversity in an urban forest is essential for promoting ecological balance, improving resilience to pests and diseases, and providing a variety of habitats for wildlife. A common guideline in this context emphasizes incorporating various tree species rather than relying on a few. This approach helps ensure that if one species becomes susceptible to a disease, others will thrive, thus sustaining the overall health of the urban forest ecosystem. Composting, while beneficial for enhancing soil health and providing nutrients to trees, does not directly relate to the strategic planning and management practices aimed at preserving species diversity. Instead, guidelines for species diversity would focus on selecting a wide range of tree species, considering factors such as the environment, site conditions, and the ecological needs of the area. Other options listed, while relevant to urban forestry in different contexts, do not specifically address the goal of maintaining species diversity in an urban forest setting. Thus, promoting a variety of tree species is critical for achieving that diversity, making it a foundational guideline for urban forest management.
