A commonly used set of methods for appraising trees was developed by:

  1. False

  2. Council of Tree and Landscape Appraisers (CTLA)

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

  4. Tree Ordinances

The correct answer is: Council of Tree and Landscape Appraisers (CTLA)

The correct answer is B: Council of Tree and Landscape Appraisers (CTLA). The CTLA has established widely recognized methods for appraising trees, including the Tree Appraisal Method (TAM) and the Guide for Plant Appraisal. These methods provide a systematic approach to assigning a dollar value to trees based on factors such as species, size, condition, location, and more. It is important for arborists and tree care professionals to be familiar with these methods when assessing the value of trees in various settings. Option A is irrelevant as it states 'False', which does not provide any relevant information related to the question. Option C is unrelated to the question as it asks about maintaining species diversity in an urban forest, which is a different topic from tree appraisal methods. Option D, Tree Ordinances, are regulations and laws related to trees, and while they are important for tree care and management, they are not specifically related to the methods for appraising trees developed by the Council of Tree and Landscape Appraisers.
