Tree Internships information

What is a tree internship?

Tree internships are educational and hands-on training opportunities for individuals interested in arboriculture, forestry, environmental science, or related fields. These internships typically involve working with trees in urban or natural environments, assisting with tree planting, maintenance, research, and conservation projects. Interns gain practical experience and knowledge about tree care, ecosystem management, and sustainability practices, often working alongside professionals such as arborists or forest managers.

What kinds of hands-on experiences can I expect during a tree internship, and how do these prepare me for a career in arboriculture or forestry?

During a Tree Internship, you can expect to participate in a variety of fieldwork activities such as tree planting, pruning, disease identification, and data collection on tree health. You'll often work outdoors alongside experienced arborists, learning proper use of tools and safety protocols. These experiences provide valuable practical skills, a deeper understanding of urban forestry or conservation practices, and networking opportunities within the field. This groundwork is essential for pursuing advanced roles in arboriculture, forestry management, or environmental science after your internship.

What are the key skills and qualifications needed to thrive in a tree internship, and why are they important?

To thrive in a tree internship, you need a basic knowledge of arboriculture, plant biology, and environmental science, often supported by relevant coursework or training. Familiarity with field equipment such as chainsaws, pruning tools, and GIS mapping systems is typically required. Strong observational skills, teamwork, and a commitment to safety make candidates stand out in this role. These abilities are crucial for effectively supporting tree care operations, ensuring safety, and contributing to environmental stewardship.

What is the difference between Tree Internships vs Arborist?

AspectTree InternshipsArborist
Required CredentialsTypically no formal certification, but some may have basic safety or forestry trainingCertifications like ISA Certified Arborist often required
Work EnvironmentFieldwork involving planting, pruning, and maintenance of treesFieldwork focused on tree care, diagnosis, and removal
Employer & Industry UsageInternships offered by forestry departments, environmental organizations, and landscaping companiesProfessional role in landscaping, municipal services, and tree care companies

Tree Internships provide hands-on experience in tree care and forestry, often as entry-level positions or training opportunities. Arborists are certified professionals specializing in diagnosing and maintaining trees. While internships focus on learning and gaining experience, arborists perform advanced tree care tasks. Both roles are essential in the tree care industry, but internships are typically temporary and educational, whereas arborists are full-time specialists.

Job description

The Research Technician Fellowship is intended to welcome undergraduate students who are interested in learning about tree science. No experience is necessary. Fellows will be mentored and trained as they assist in laboratory and/or field operations under close supervision. 

To apply, individuals will complete the online application form; while encouraged, a resume and cover letter are not required. A brief true/false survey will be sent immediately to confirm interest, followed by a required questionnaire within one week to determine project interest and allow applicants an opportunity to provide additional details. Applications will be accepted until positions are filled.    

Project descriptions:

  • Herbarium and Forest Ecology Lab (part-time, September 2026 - May 2027): Trees at The Morton Arboretum record and preserve decades to centuries of information on growth responses to environmental conditions in their annual rings. As part of the Arboretum’s Herbarium, we have a formal archival collection of wood cross-sections of trees that have died at the Arboretum. Student interns will primarily focus on database migration to incorporate wood specimen information into the master Herbarium database (BRAHMS). Interns will also assist with the full cycle of collections development and curation, including specimen cataloging, sample preparation, and digitization.
    Special considerations: Interns must be able to lift 30+ pounds with assistance (15 pounds unassisted) and be comfortable using computers. May involve some use of power tools, including belt sanders and potentially saws (after training). Applicants do not need to know how to use these tools already, but must not be afraid to learn.
     
  • Plant Pathology Lab (part-time, September 2026 - May 2027): The Plant Pathology Laboratory offers hands-on experience with molecular, microbiological, and diagnostic techniques used to study plant diseases and soil organisms. Interns will contribute to research focused on the identification, characterization, and ecology of plant pathogens, fungi, oomycetes, nematodes, and other organisms that influence plant health.
    Responsibilities may include collecting plant and soil samples, isolating and culturing fungi and oomycetes, extracting and enumerating nematodes, preparing laboratory materials and culture media, using microscopes to observe and quantify organisms, maintaining accurate research records, and assisting with ongoing laboratory and field research projects. Through these activities, individuals have the opportunity to develop practical skills in plant pathology, microbiology, soil ecology, laboratory techniques, data collection, and scientific research methods.
  • Root Biology Lab (part-time, September 2026 - May 2027): The Root Biology Lab at The Morton Arboretum works to connect roots, fungi, and rhizosphere processes belowground to whole-plant and ecosystem science. We work in field, lab, and computational settings. This fellowship will expose the student to a mix of all three settings in an effort to build a breadth of experience, likely with emphasis on lab work analyzing enzyme activities from field collected soils. We seek a student with a desire to learn more about roots, fungi, and plants to join our supportive and passionate group.

Essential Functions may include: 

  • Provide support to a scientist for the implementation of research and related projects.

  • Assist with data and sample collection, sample processing, data analysis, and record keeping on research and related projects. 

  • Operate and maintain laboratory equipment, and perform routine lab maintenance by keeping laboratory and field equipment in good working order. 

  • May maintain living plants in the field and greenhouse. 

  • May voucher and assist with the curation of herbarium specimens. 

  • Demonstrate alignment with the Arboretum’s employee core values

  • Other duties as assigned.

Qualifications: Current enrollment in an Associate or Bachelor’s degree program, with an interest in studying biology, environmental sciences, or a related field. Must be over the age of 16. Organization and independent working skills preferred. Willingness and eagerness to learn necessary field, laboratory, and library research skills required. Experience with database, spreadsheet, and statistical/graphics computer programs, and Google applications beneficial. Depending on the position, may require possession of a valid driver’s license, which is subject to insurability and an annual Motor Vehicle Record (MVR) report.

Success Factors: Ability and willingness to work in laboratory and field environments. Good written and oral communication skills. Clear thought, visual acuity, and manual dexterity needed. 
Physical Demands and Work Environment for all positions: The physical demands and work environment characteristics described here are representative of those that must be met by an employee to successfully perform the essential functions of this job.
