Final answer:
The ABCFP reserves the titles 'Professional Forester' and 'Forest Technician' for its registrants, who can use 'Registered Professional Forester (RPF)' and 'Registered Forest Technologist (RFT)' respectively. Titles such as 'Master Forester' and 'Certified Arborist' are not designated by the ABCFP.
Step-by-step explanation:
The titles reserved for ABCFP (Association of BC Forest Professionals) registrants are c) Professional Forester and d) Forest Technician. The title of Master Forester is not a designation used by the ABCFP, and Certified Arborist is a title designated by the International Society of Arboriculture (ISA). The ABCFP is the professional association responsible for registering and regulating forest professionals in British Columbia, Canada.
Individuals who earn the title of Professional Forester are entitled to use the title 'Registered Professional Forester (RPF)' and those who become Forest Technicians are entitled to use 'Registered Forest Technologist (RFT)'. These designations are a testament to the education, experience, and professional practice standards met by the individual in the field of forestry.
