Tree Services Glossary

1. Arborist: A trained and certified professional specializing in tree care and maintenance. Arborists are skilled in tree health assessment, Pruning, and tree removal techniques.

2. Tree Pruning: The selectively trimming branches and limbs from a tree to enhance its health, appearance, and safety. Pruning aims to remove dead, diseased, or damaged components while promoting proper growth and structure.

3. Tree Removal: The complete tree extraction from its location. Tree removal is usually done when a tree is dead, hazardous, diseased, or inappropriately situated.

4. Tree Trimming: Similar to Pruning, tree trimming involves the removal of specific branches or foliage to improve the tree’s shape and overall aesthetics.

5. Tree Cutting: A general term used to describe any form of tree removal, whether partial (trimming/pruning) or complete removal.

6. Stump Grinding: The process of mechanically grinding down a tree stump after tree removal, leaving the area ready for replanting or other landscaping activities.

7. Tree Cabling and Bracing: Techniques are used to support weak or structurally compromised trees. Cables and braces are installed to reduce the risk of branches or the entire tree falling.

8. Tree Health Assessment: An evaluation carried out by an arborist to determine the overall health of a tree. It involves inspecting for signs of diseases, pests, and structural issues that may affect the tree’s vitality.

9. Tree Preservation: Protecting and maintaining trees, especially during construction or development projects, to ensure their long-term survival and well-being.

10. Tree Risk Assessment: An evaluation performed to identify potential risks and hazards associated with a tree. It helps determine whether a tree needs removal or other management practices to mitigate risks.

11. Crown Thinning: A pruning technique that selectively removes some inner branches of the tree’s crown to increase light penetration and air circulation, reducing the risk of wind damage.

12. Crown Lifting (Raising): Pruning the lower branches of a tree to create clearance beneath the crown, often for pedestrian access, vehicles, or to improve visibility.

13. Crown Reduction: The process of reducing the overall size of a tree’s crown by selectively cutting back branches. This is often done to balance the tree’s shape or to prevent interference with utility lines or structures.

14. Root Pruning: The practice of trimming or cutting roots, usually done during transplanting or to prevent damage to nearby structures or pavements.

15. Tree Fertilization: The application of nutrients, such as nitrogen, phosphorus, and potassium, to the soil around a tree to improve its health and growth.

16. Tree Planting: The process of carefully installing a young tree in a designated area, ensuring proper depth and root ball preparation for optimal growth.

17. Emergency Tree Services: Immediate tree services are provided in response to storm damage, fallen trees, or other urgent tree-related incidents.

18. Wood Chipping: The process of converting tree branches and limbs into wood chips, which can be used for mulch, erosion control, or other landscaping purposes.

19. Tree Canopy: The upper branches and foliage of a tree that forms its outermost layer, often referred to as the “crown” of the tree.

20. Tree Climbing: The skillful practice of ascending and working within a tree using specialized climbing equipment, commonly done by arborists for Pruning and other services.

21. Deadwooding: Removing dead or dying branches from a tree. Deadwooding not only improves the tree’s appearance but also eliminates potential hazards.

22. Pollarding: A severe pruning technique where the upper branches of a tree are cut back to the trunk, promoting new growth and maintaining the tree at a specific height.

23. Coppicing: A traditional tree management method where the tree is cut back to ground level, encouraging the growth of new shoots for various purposes, such as fuel, fencing, or crafting.

24. Crown Cleaning: Pruning to remove dead, dying, or diseased branches and any other undesirable materials from the crown of a tree.

25. Transplanting: The process of relocating a mature tree from one location to another. This delicate operation requires proper planning and care to ensure the tree’s survival.

26. Tree Watering: Providing sufficient water to a tree, especially during dry periods, to maintain its health and promote proper growth.

27. Tree Health Care Plan: A comprehensive plan developed by an arborist to address the specific needs of a tree or group of trees, outlining ongoing care, treatments, and maintenance schedules.

28. Soil Aeration: A process that involves perforating the soil to allow better air, water, and nutrient penetration to the tree’s root zone.

29. Mulching: Covering the soil around a tree with organic materials, such as wood chips or leaves, to retain moisture, regulate temperature, and improve soil fertility.

30. Canopy Pruning: Selective Pruning of the outer edges of a tree’s crown to shape it and remove branches that extend beyond the desired silhouette.

31. EAB (Emerald Ash Borer): A highly destructive invasive beetle species that targets ash trees, causing significant damage and often leading to tree mortality.

32. Tree Injection: A method of delivering pesticides, fertilizers, or other treatments directly into a tree’s vascular system to address specific issues like pests or nutrient deficiencies.

33. Girdling Roots: When roots grow in a circular pattern around the base of a tree’s trunk, potentially restricting water and nutrient flow, leading to health issues.

34. Root Collar Excavation: The process of uncovering the root collar (where the roots meet the trunk) to inspect and correct any issues affecting the tree’s health.

35. Air Spading: Using compressed air to safely excavate the soil around tree roots without causing damage, often used during construction projects.

36. Crown Restoration: Pruning to restore the shape and structure of a tree that has been damaged or improperly pruned.

37. Hazard Tree Assessment: An evaluation is carried out to identify trees that threaten people, property, or infrastructure and require immediate action.

38. Deciduous Trees: Trees that shed their leaves seasonally in response to changes in temperature and daylight.

39. Evergreen Trees: Trees that retain their leaves or needles throughout the year, providing greenery even in winter.

40. Drought Stress: The negative impact of prolonged dry periods on a tree’s health, leading to reduced growth and increased vulnerability to pests and diseases.

41. Arboriculture: The study and practice of cultivating and managing trees, including tree care, planting, and maintenance.

42. Canopy Cover: The area covered by a tree’s branches and foliage when viewed from above.

43. Endangered Species: Tree species at risk of extinction, often due to habitat loss or human activities.

44. Grafting: A horticultural technique where tissues from one tree (scion) are inserted into another tree (rootstock) to create a new plant with desired characteristics.

45. Lopping: A non-professional and potentially harmful method of tree pruning that involves cutting branches without considering the tree’s health or structure.

46. Suckers: Fast-growing shoots that emerge from the base of a tree or its roots, often considered undesirable and requiring removal.

47. Topiary: The art of shaping trees or shrubs into ornamental and artistic forms by carefully Pruning and training the plant’s growth.

48. Windbreak: A row of trees or shrubs planted to reduce wind speed and protect against wind erosion and damage.

49. Xylem and Phloem: Vascular tissues in trees responsible for transporting water and nutrients (xylem) and sugars (phloem) throughout the plant.

50. Crown Dieback: A condition where the upper portion of a tree’s canopy gradually declines and dies due to various stress factors.

51. Bonsai: A Japanese art form that involves cultivating small trees in containers and shaping them through careful Pruning and training.

52. Mycorrhizae: Symbiotic fungi that form a beneficial relationship with tree roots, assisting in nutrient uptake and enhancing the tree’s overall health.

53. Transpiration: The process by which trees release water vapor through their leaves, contributing to water movement from roots to leaves.
