Final answer:
Certified Arborists is the category that only holds a reserved title and does not include reserved practice rights. Reserved titles are protected but do not limit the practice to holders, unlike reserved practices which are regulated activities for title holders only.
Step-by-step explanation:
The category that only holds a reserved title (non-reserved practice) among the options provided is Certified Arborists. Reserved titles are typically used in professions where regulatory bodies protect the use of certain titles to individuals who have met specific educational and professional criteria, but do not restrict the actual practice of the profession solely to titleholders. In contrast, reserved practice is a regulatory term meaning that only individuals licensed or registered with the profession\'s regulatory body are legally permitted to perform certain activities or tasks.
For example, anyone may practice certain forestry-related tasks but only those who have met the criteria can call themselves Certified Arborists. Meanwhile, professions with reserved practice might include Professional Foresters or Master Foresters, where the title protection likely goes hand-in-hand with a legal restriction on the work they are allowed to perform. Forest Technicians may or may not have a reserved title or practice depending on regional regulations.
