Where tree work leads: crew lead, utility, urban forestry, consulting and more

The jobs a climber or groundie can move into, as the official career profiles in each country describe them, and what those profiles say employers ask for.

Checked against the sources at the bottom of this page on October 5, 2026. Rules, fees and pay change: the source has the last word.

This page lists roles that sit next to or above hands-on tree work. For each one it says what the government career profile for that job says it is and what qualifications the profile names. A profile describes a job group, not a particular employer. Some of the profiles cover wider groups than tree work, and the page says so where that matters. Pay and outlook numbers are on the career outlook page, and pay by country is on the pay page.

The starting point in each country

The profiles below start from different places, so the starting job has a different name in each country.

CountryProfileWhat it says about entry
United StatesTree trimmers and pruners (O*NET and BLS)No formal credential needed, trained on the job
CanadaArborists and tree service technicians (NOC 22114)College program, apprenticeship or supervisory experience

Crew leader or foreman

United States

The Bureau of Labor Statistics Occupational Outlook Handbook says on its grounds maintenance workers page that workers in this group typically do not need a formal educational credential and are trained on the job, and that some become crew leaders or move into other supervisory positions. The group includes tree trimmers and pruners. The O*NET profile for first-line supervisors of landscaping, lawn service and groundskeeping workers lists reported titles such as Grounds Foreman and Grounds Crew Supervisor. It puts the job in Job Zone 3, where most occupations call for vocational school, related experience or an associate degree. That profile is not specific to tree work.

Canada

The National Occupational Classification profile for contractors and supervisors in landscaping, grounds maintenance and horticulture services (NOC 82031) lists "tree service contractor" and "landscaping foreman" among its titles. It names tree service companies among employers. It says experience as a landscape or horticulture supervisor or technician is required, and that a college diploma, specialized courses or industry training are usually required.

United Kingdom

The National Careers Service tree surgeon profile lists becoming a supervisor or manager as one thing a tree surgeon could do with experience.

Australia and New Zealand

The Tahatu profile for a grounds maintenance supervisor says the job is managing, supervising and recruiting landscaping and grounds maintenance crews, and that supervisors may prepare quotes for customers. It is a grounds job, not a tree job. The Your Career arborist page for Australia did not name a supervisor step.

Utility line clearance

None of the official profiles linked here describes line clearance as a job of its own. The closest listings treat it as a part of arborist work or put the work in a separate line trade.

  • United States: the BLS says tree trimmers and pruners cut branches to clear utility lines, roads and sidewalks. O*NET lists the right-of-way for roads, sidewalks or utilities in its description of the job. O*NET has a different profile for electrical power-line installers and repairers, which installs and repairs cables and wires. That is a line trade, not tree work.
  • Canada: the Job Bank requirements page for arborists lists Arborist and Utility Arborist as regulated job titles in Ontario, with Skilled Trades Ontario as the regulatory body. Other provinces are listed with their own regulators. The list is on the Job Bank requirements page. The NOC profile for electrical power line and cable workers (72203) is a separate trade, with a three or four year lineman apprenticeship.
  • New Zealand: Tahatu lists "utility arborist" as another name for an arborist, and its qualification list for arborists includes a Level 3 certificate in electricity supply (utility arboriculture). Its line mechanic profile is a separate job that needs an apprenticeship and registration with the Electrical Workers Registration Board.

The guide on working near power lines covers what the law and standards say about working near lines.

Urban forestry and tree officer roles

United States

The BLS profile for conservation scientists and foresters describes urban foresters as people who work in cities and manage the trees, with a focus on air quality, shade and storm water runoff. It gives a bachelor's degree in forestry, natural resources or a related field as the typical entry education for the group. The conservation scientists and foresters page covers more than city trees.

United Kingdom

For council roles, the arboricultural officer profile (also called tree officer) says the job is managing and maintaining trees for local councils and arboricultural contractors. Its task list includes advising on tree preservation orders in planning applications, managing trees in parks, on housing estates and at the roadside, and assessing tree damage after storms. For a direct application it says employers usually want experience in a related job, such as arboricultural assistant or tree surgeon, and a nationally recognised arboricultural qualification such as the Level 4 Certificate in Arboriculture. It also lists an assistant officer post at a local authority or landscaping firm for people with some qualifications or experience.

The Institute for Apprenticeships and Technical Education publishes two standards on this ladder. The Arboriculturist standard (level 4) describes the job as tree inspections and surveys, with titles including tree officer and arborist sales representative. It says there are no statutory entry requirements, and that parts of the industry are likely to want a level 2 or 3 arboricultural qualification and practical experience. The Professional Arboriculturist standard (level 6) describes managing peri-urban and urban trees, with titles such as principal tree officer and urban tree manager.

Canada, Australia and New Zealand

No separate official profile for a municipal tree officer is listed for these countries. Tahatu lists "urban forester" and "arboriculture consultant" as other names for an arborist. The guide on tree protection laws covers what the law says about protected trees.

Plant health care technician

O*NET lists Plant Health Care Technician among the reported job titles for tree trimmers and pruners. The Australian Your Career profile says arborists treat trees with fertilisers and insecticides and spray and dust plants to control insects and disease. The Canadian NOC profile says arborists diagnose tree problems and disease and apply treatments such as pruning, spraying and injecting. Spraying can bring licence rules. The BLS says most states require licensing for workers who apply pesticides. The NOC profiles say a provincial licence to apply chemicals may be required. See pesticide licences by country for the rules each agency publishes.

Tree inspector or risk assessor

The UK tree surgeon profile lists working with clients to produce tree survey reports among a tree surgeon's tasks. The UK Arboriculturist standard above puts inspection at the centre of the level 4 job. Elsewhere, risk assessment is mostly named as a credential, not as a job profile. Tree risk assessment covers who runs those programs and what they say.

Consulting arborist

The UK arboricultural officer profile says an officer could, with experience, work as a consultant advising organisations on tree management, conservation and safety. The Tahatu arborist profile lists arboriculture consultant as another name for the job. The UK Arboriculturist standard lists arboricultural consultant among its titles. The credentials that consulting bodies describe are in becoming a consulting arborist.

Sales or estimator

  • United States: the O*NET supervisor profile says the work may involve reviewing contracts, answering customers' questions about methods, materials and price ranges, and preparing estimates according to labor, material and machine costs.
  • Canada: the NOC contractor and supervisor profile lists tendering bids on contracts among the duties.
  • United Kingdom: the Arboriculturist standard lists arborist sales representative as a job title.
  • New Zealand: the Tahatu arborist profile lists estimating costs for tree work among the tasks.

Trainer or assessor

The UK arboricultural officer profile says officers can find teaching opportunities with training providers that run arboriculture courses. The profiles for the other four countries do not name a trainer or assessor role. How courses and assessors are set up is covered in choosing a course.

Business owner

Several profiles name this step directly.

  • United States: the BLS says some grounds maintenance workers use their experience to start their own business.
  • Canada: the NOC profile says contractors may be self-employed and may manage the operations of their own company.
  • United Kingdom: the tree surgeon profile lists starting your own business among the things you could do with experience.

The profiles do not cover insurance, licences or tax. The guides on starting a tree business and insurance cover point to the agencies that do.
