A person who specializes in the science and practice of growing, managing, and caring for trees.
From arboriculture + -ist (suffix denoting a person who practices or specializes in something). The -ist suffix comes from Latin and Greek and is one of English's most productive professional designation patterns.
While 'arborist' is more common, 'arboriculturist' emphasizes the scientific and cultivation expertise—the difference is like 'doctor' (general) versus 'cardiologist' (specialized), both correct but different emphasis.
Arboriculture emerged as a professional field in 19th–20th century Europe and North America, professions historically gatekept as male-dominated. The -ist suffix became gendered when early practitioners were predominantly men, creating male-default assumptions about who studies and practices tree care.
Use in context of actual individuals without gender assumption. 'The arboriculturist examined the oak' works equally for any gender, but avoid 'he/the arboriculturist' unless referring to a specific male person.

Women have contributed to arboriculture since the early 20th century (e.g., landscape designers, conservation arborists), though early literature underrepresented them. Modern arboriculture actively recruits women into field and management roles.
