Duties and Responsibilities
Trees are everywhere and provide people with many benefits. They offer shade, produce oxygen, and provide food. They keep streets and cities cool and prevent soil erosion. And just like a person, trees need proper care and nutrients to stay healthy. An arborist provides this kind of care. Their duties and responsibilities typically include:

  • Tree Care and Maintenance: Arborists assess the health, structure, and condition of trees to identify any issues or potential hazards. They perform various tree care tasks such as pruning, trimming, and shaping to promote healthy growth, improve aesthetics, and enhance safety. Arborists also provide recommendations for fertilization, watering, and pest management to maintain the vitality of trees.
  • Tree Planting and Transplanting: Arborists select appropriate tree species for specific sites based on factors such as soil conditions, climate, and space availability. They oversee tree planting projects, ensuring proper techniques are used to promote successful establishment and growth. Arborists may also transplant trees from one location to another, taking care to minimize stress and damage to the tree's root system.
  • Diagnosis and Treatment of Tree Diseases and Pests: Arborists diagnose and treat tree diseases, insect infestations, and other health issues that may affect tree health and vitality. They identify symptoms of common tree ailments, such as fungal infections, insect damage, or nutrient deficiencies, and recommend appropriate treatment options, such as pruning, spraying, or soil amendments, to mitigate the problem.
  • Tree Removal and Hazard Assessment: Arborists assess the structural integrity and stability of trees to determine if they pose a safety risk to people or property. They may recommend tree removal in cases where trees are dead, diseased, or structurally unsound and cannot be safely preserved. Arborists use specialized equipment and techniques to safely fell and remove trees, minimizing damage to surrounding vegetation and structures.
  • Consultation and Risk Assessment: Arborists provide expert advice and consultation to property owners, developers, municipalities, and other stakeholders regarding tree management, preservation, and risk mitigation strategies. They conduct tree risk assessments to evaluate the likelihood of tree failure or property damage and recommend measures to reduce risks and liabilities associated with trees.
  • Tree Preservation and Conservation: Arborists advocate for the preservation and conservation of trees and natural landscapes by promoting sustainable tree care practices, advocating for tree protection ordinances, and participating in community tree planting and conservation initiatives. They may also collaborate with environmental organizations, government agencies, and community groups to promote tree stewardship and urban forestry efforts.

The workplace of an arborist is predominantly outdoors, where they spend the majority of their time working among trees and natural landscapes. Arborists may work in a variety of settings, including urban areas, suburban neighborhoods, parks, forests, and commercial properties. Depending on their specific role and responsibilities, arborists may also work in remote or rural areas with expansive forests or natural habitats.

Arborists often work in diverse weather conditions, ranging from hot and sunny days to cold and rainy weather.
