When developing or altering a property, protecting existing trees is often a critical component of the planning process. Many local governments require a Tree Protection Management Plan (TPMP) as part of the application for planning permits. These plans are essential for preserving trees, complying with regulations, and minimizing environmental impacts during construction or land development.
What is a Tree Protection Management Plan?
A TPMP is a detailed arboricultural report for planning that outlines measures to safeguard existing trees during development activities. It identifies the trees to be retained, details their condition, and specifies strategies to ensure their health and structural integrity are maintained throughout the project.
Key Components of a TPMP
Tree Survey and Assessment
- Identification of all trees on the site, including species, size, health, and significance
- Categorization of trees based on retention value
Tree Protection Zones (TPZ) and Structural Root Zones (SRZ)
- Definition of protected areas around retained trees to prevent damage to roots, trunks, and canopies
- Establishment of fencing or barriers to demarcate TPZ
Impact Assessment
- Analysis of construction or development activities that may impact trees (e.g., excavation, grading, or equipment movement)
- Recommendations for minimizing or mitigating these impacts
Protection Measures
- Installation of ground protection mats or mulching within TPZs
- Restrictions on the use of heavy machinery or storage of materials near trees
Maintenance and Monitoring
- Regular inspections by a certified project arborist to ensure compliance with protection measures
- Ongoing tree care, such as watering, fertilizing, and pruning, as necessary
Post-Development Tree Care
- Recommendations for the long-term health and maintenance of retained trees after project completion
Why Are TPMPs Important?
- Legal Compliance: Many planning permits mandate TPMPs to protect heritage, native, or significant trees
- Environmental Conservation: Preserving mature trees helps maintain biodiversity, improve air quality, and stabilize soil
- Aesthetic and Property Value: Retained trees enhance the visual appeal and increase the value of properties
Who Prepares a TPMP?
Tree Protection Management Plans should be prepared by an AQF certificate 5 consulting arborist with expertise in tree health and protection during construction. Their professional input ensures the plan is thorough, effective, and aligns with tree permit requirements.
Tips for Developers and Property Owners
- Engage Early: Consult with an arborist before submitting a planning application to integrate tree protection into your project design
- Stay Informed: Understand the local tree protection regulations and tree permit requirements
- Collaborate: Work closely with planners, arborists, and construction teams to ensure tree protection measures are practical and enforceable.
A well-prepared Tree Protection Management Plan not only satisfies legal requirements but also contributes to sustainable development and the long-term health of the environment.
