Tree Care Industry Overview
The US tree care industry encompasses the professional maintenance, removal, planting, and health management of trees in residential, commercial, municipal, and utility right-of-way settings. Generating approximately $25-30+ billion in annual revenue, the industry employs hundreds of thousands of workers across approximately 20,000-25,000+ tree care companies ranging from solo operators with a pickup truck and chainsaw to large regional and national firms operating fleets of bucket trucks, cranes, and chippers across multiple states. Tree care services include tree pruning and trimming (the most common service, representing the largest share of industry revenue), tree removal (including hazardous tree removal requiring specialized rigging, crane-assisted removal, and emergency storm damage response), tree planting and transplanting, tree health care (pest and disease management through integrated pest management/IPM programs, deep root fertilization, soil amendment, and growth regulator application), stump grinding and removal, cabling and bracing (structural support systems for trees with weak branch attachments or codominant stems), lightning protection, and consulting arboriculture (tree risk assessment, appraisal, preservation planning, and expert witness services).
The largest tree care companies in the US include Davey Tree Expert Company (one of the oldest and largest tree care companies, founded in 1880, employee-owned, operating across the US and Canada with approximately $1.5+ billion in annual revenue spanning residential/commercial tree care, utility vegetation management, and environmental services), Bartlett Tree Experts (a large national tree care company specializing in residential and commercial arboriculture, operating approximately 100+ offices across the US), The Davey Tree Expert Company's utility services division and Asplundh Tree Expert (now part of Asplundh, which is owned by Utility One Source; Asplundh is the largest utility vegetation management company in the world with approximately $4+ billion in annual revenue), ACRT Services (utility vegetation management consulting), and Wright Tree Service (utility line clearance). The residential and commercial tree care market, as distinct from utility vegetation management, is highly fragmented, with the vast majority of companies being small, locally operated businesses.
ISA Certification and TCIA Membership Databases
ISA (International Society of Arboriculture) is the global professional organization for arboriculture, headquartered in Atlanta, Georgia (relocated from Champaign, Illinois). ISA's Certified Arborist credential is the most widely recognized professional certification in the tree care industry, with approximately 38,000-40,000+ active ISA Certified Arborists in the US (approximately 50,000+ worldwide). The ISA Certified Arborist credential requires passing a comprehensive examination covering tree biology and identification, soil science, tree nutrition and fertilization, tree pruning and removal, tree risk assessment, pest and disease management, tree planting, urban forestry, and worker safety, along with a minimum of three years of full-time experience in arboriculture or a related field (or a combination of education and experience). ISA also offers advanced credentials including the ISA Board Certified Master Arborist (BCMA, the highest level of ISA certification, requiring additional examination and peer review), ISA Certified Arborist Utility Specialist, ISA Certified Arborist Municipal Specialist, and ISA Tree Risk Assessment Qualification (TRAQ).
The ISA website features a searchable "Find an Arborist" directory that allows consumers and businesses to search for ISA Certified Arborists by location (city, state, or ZIP code) and credential level. This directory provides the arborist's name, credentials held, company affiliation, city and state, and in many cases phone number and website. For scraping purposes, this directory is among the highest-quality data sources for the tree care industry because ISA certification serves as a reliable indicator of professional competence and active engagement in the industry.
TCIA (Tree Care Industry Association) is the primary trade association representing commercial tree care companies, with approximately 2,300+ member companies. TCIA provides business management resources (including the TCIA Accreditation program, which evaluates tree care companies against industry standards for safety, training, business practices, and consumer satisfaction), safety standards and training programs (TCIA develops ANSI standards for tree care operations, including ANSI Z133 -- Safety Requirements for Arboricultural Operations, the primary workplace safety standard for the tree care industry, and ANSI A300 -- Tree Care Operations Standards), and the annual TCI EXPO (the largest tree care industry trade show, approximately 3,000-4,000+ attendees). TCIA's member directory is searchable online and provides company name, location, contact information, services offered, and accreditation status.
Navigate to the ISA Certified Arborist directory (searchable online by location and credential), TCIA member directory and TCI EXPO conference databases, state arborist licensing databases (some states, including Connecticut, Louisiana, Maryland, and others, require arborist licensing; licensing databases provide licensee name, company, license number, and contact information), municipal tree contractor approved vendor lists (many cities maintain lists of approved or preferred tree care contractors for work on public property or within right-of-way areas), utility vegetation management contractor databases (electric utilities maintain lists of approved contractors for line clearance work), and tree care trade publication directories (Tree Care Industry Magazine/TCI, Arborist News/ISA). Save ISA directories, TCIA member data, state licensing records, and contractor lists as HTML or CSV. Upload to Email Extractor to extract arborist, tree care company owner, operations manager, safety director, and urban forestry manager email addresses from ISA, TCIA, state licensing, and industry databases for equipment, safety gear, software, training, and contractor outreach.
Tree Care Technology and Equipment Trends
The tree care industry, while traditionally labor-intensive and equipment-driven rather than software-driven, is experiencing increasing technology adoption in several areas. Tree care business management software (ArborGold, Arborgold, SingleOps, Service Autopilot, Jobber, and general field service management platforms like ServiceTitan and Housecall Pro adapted for tree care) provides customer relationship management, job estimating and proposal generation, scheduling and dispatch, crew management, GPS fleet tracking, invoicing, and financial reporting. Tree inventory and management software used by municipalities and institutional tree managers (TreePlotter by PlanIT Geo, Davey Resource Group/DRG i-Tree tools, ArborAccess, TreeManager) provides GIS-based tree inventory mapping, maintenance history tracking, work order management, and urban forest canopy analysis.
The tree care equipment market includes specialized vehicles and heavy equipment (aerial lift trucks/bucket trucks manufactured by Altec, Terex/Hi-Ranger, and Versalift; knuckleboom loader trucks; log trucks; skid steer and track loader attachments), tree chippers (Bandit Industries, Vermeer, Morbark, Rayco, and Woodsman, with chipper prices ranging from approximately $30,000-$150,000+ depending on capacity and features), stump grinders (Vermeer, Rayco, Bandit, Carlton, with prices from approximately $10,000 for walk-behind units to $100,000+ for large track-mounted machines), chainsaws and arborist climbing gear (Stihl and Husqvarna dominate the professional chainsaw market; rope and harness climbing systems from Teufelberger, Samson, Yale Cordage, and Buckingham; throwline systems from Notch Equipment and WesSpur), and plant health care equipment (spray rigs, soil injection systems, and trunk injection systems from Arborjet, Mauget, and Rainbow Treecare Scientific Advancements).
Drone technology is emerging as a useful tool in arboriculture for aerial tree assessment (photographing tree canopies from above to identify dieback, pest damage, structural defects, and decay that may not be visible from the ground), tree inventory and canopy mapping for municipal urban forestry programs, and seed bombing and reforestation applications. LiDAR-equipped drones and satellites can generate detailed 3D models of tree canopy structure for utility vegetation management planning and urban canopy assessment at landscape scale.
