Associations, magazines and podcasts for tree workers

This page lists real organisations and publications. None of them has any link to ArboNation. ArboNation is a preview site and has no members, partners or sponsors. Each entry says what the organisation's own page says it offers.

United States

ISA, the International Society of Arboriculture

ISA sells membership to individuals and runs education and credentials. The ISA benefits page lists print subscriptions to Arborist News or the research journal Arboriculture & Urban Forestry, discounts on education, conferences and credentials, extra members-only CEU quizzes, a job listing option in the ISA Career Center, and a member directory.

The prices below are from ISA's membership types page:

Type	Price	Who it is for
Professional	US$135	Anyone working in arboriculture, or anyone interested in planting or preserving trees
Student	Free through a local chapter, or US$30	School and college students who meet the page's rules
Senior	US$70	Retired professional members aged 62 or older with at least 10 years in good standing
Associate	US$70	People living where English is not the official language

Most climbers join through a local ISA chapter as well. ISA's chapters page lists one body for each of these US states: Florida, Illinois, Indiana, Iowa, Kentucky, Michigan, Minnesota, New Jersey, New York, Ohio, Texas, Utah and Wisconsin. Others cover several states:

Chapter	States it covers
Rocky Mountain	Colorado, Montana, New Mexico, Wyoming
Midwest	Kansas, Missouri, Nebraska, Oklahoma
Mid-Atlantic	Washington, D.C., Maryland, Virginia, West Virginia
Western	Arizona, California, Hawaii, Nevada
New England	Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, Vermont
Penn-Del	Pennsylvania, Delaware
Southern	Alabama, Arkansas, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, Puerto Rico, Virgin Islands
Pacific Northwest	Alaska, Idaho, Oregon, Washington, and British Columbia in Canada

The Dakotas and Georgia are listed as associate organizations rather than chapters. Fees below are what each body's own page shows, and they change:

Illinois: US$55 a year, or US$190 combined with ISA. See the Illinois tiers page. Students US$25.
Wisconsin: US$50 for professionals, apprentices included, and US$15 for students with free ISA membership, on the 2026 application form.

Mid-Atlantic: US$65, or US$55 if you already hold ISA membership, on the Mid-Atlantic page.
New England: US$35 a year, on the New England page. It lists students at US$15 with ISA and also announces free student memberships for 2026.
New Jersey: US$45, and US$25 for students with a free year of ISA, on the New Jersey page.
Penn-Del: US$55 a year, on the Penn-Del page.

Some chapters run climbing events. The Kentucky Arborists Association lists its Kentucky Tree Climbing Championship on October 23 and 24, 2026.

ISA professional affiliates

ISA's chapters page also lists four affiliates for particular kinds of work: AREA for scientists and educators, the Society of Commercial Arboriculture, the Urban and Community Forestry Society (formerly the Society of Municipal Arborists) and the Utility Arborist Association. The Urban and Community Forestry Society lists its Municipal Forestry Institute on Jekyll Island, Georgia, from February 21 to 26, 2027, on its home page.

Tree Care Industry Association (TCIA)

TCIA calls itself the largest and longest running non-profit trade association for the tree care industry, advancing tree care businesses since 1938, so it is aimed more at companies than at individual climbers. It runs the TCI EXPO and publishes Tree Care Industry Magazine.

Membership is by company. TCIA's membership page sets yearly dues by tree care revenue, from US$450 for companies under US$100,000 up to US$8,000 over US$100 million. That table says it was valid from September 1, 2025 to August 21, 2026, so the amounts may have changed. The page says a company's membership covers all its employees, and that members save up to 44% on online training courses and 25% on TCI EXPO registration. TCI EXPO is listed at the Broward County Convention Center in Fort Lauderdale, with the trade show on November 12 to 14, 2026 and a pre-conference on November 11, on the TCI EXPO page.

Utility Arborist Association (UAA)

The UAA calls itself the voice of the right-of-way vegetation management industry, so it is for people in utility vegetation management. Its join page lists the Newsline publication, webinars, CEU quizzes, a directory, and discounts on summits and meetings. Individual membership is US$75 a year, with an auto-renew option. Students enrolled in school are free with yearly proof of enrolment. Companies can buy memberships for several employees at discounted rates.

Society of Commercial Arboriculture (SCA)

The SCA describes itself as connecting a global group of commercial tree workers to talk about the business side of the trade. Its home page listed a Field Day in Detroit on August 9, 2026, and its events page says it holds a RakeMaster Challenge every year at the International Tree Climbing Championship. No price is shown there.

Canada

ISA is the main body in Canada too, through local chapters. ISA's chapter list says joining both ISA and your local chapter gets you local contacts, and that regional memberships support local programs and regional tree climbing competitions. It lists four Canadian chapters:

In Ontario, the ISA Ontario Chapter
Quebec: the Quebec society, SIAQ
Atlantic, covering New Brunswick, Nova Scotia, Prince Edward Island and Newfoundland: ISA Atlantic Chapter
Prairie, covering Alberta, Manitoba and Saskatchewan: ISA Prairie Chapter

British Columbia is not a chapter of its own. ISA's list puts it with the Pacific Northwest chapter, which also covers Alaska, Idaho, Oregon and Washington. Fees from the chapters' own pages:

Chapter	Fee	Notes
Ontario	CA$110 a year	CA$297 with ISA. Students CA$75 with ISA
Prairie	CA$130 a year	Senior CA$80, student CA$20. ISA not included

On the ISA Ontario membership page it says members get the printed Ontario Arborist magazine every two months. The Prairie membership page says the quarterly Prairie Arborist newsletter and a member list of ISA Certified Arborists are included, and that ISA membership is bought separately.

United Kingdom
