Opportunities to Improve Plant Performance

Lee Gilman & Associates, LLC provides a powerful interdisciplinary approach considering both the plant and the ecosystem in which it is found. By first prioritizing opportunities to optimize a site’s fulfillment of plant growth requirements, innate potential can be maximized. By next recommending a prioritized range of integrated pest management techniques, we can see where synergies exist and develop a prognosis. When we relate these potentialities to our client’s goals and resources, an action threshold and service level offering the best value for efficient management becomes clear.

Vegetation Surveys

Understanding Your Assets

Knowledge about significant plants in your landscape supports sound decision-making and the development of a management plan. We can catalog items such as: species, size, location, condition, value, health concerns, maintenance priorities, and quantified risk. Inventory results may be reported, plotted, managed with specialized software systems and even integrated with GPS/GIS mapping layers. Maintenance efficiencies improve with better planning and tracking.

  1. Homebuyers Reports
  2. Tree Inventories
    • Reporting
    • Software Systems
    • Mapping
    • GPS/GIS Data


Quantified Tree Risk Assessment

Due Diligence

Increasingly accurate methodologies are available to assess and quantify tree risks. Minimum standards dictate a property owner’s duty of common prudence to inspect and discover possible defects in landscape and urban trees. Advanced techniques may achieve cutting-edge risk reductions. Either way, you reduce exposure to negligence claims.

  1. Structural Evaluation
  2. Site Evaluation
  3. Risk Mitigation Planning


Tree Management Plans

Helping Trees Achieve Their Potential

The genetic potential of most trees to outlive us is compromised when they are taken out of the forest and put in our built environments. Understanding and managing these compromises allows for optimal decision-making, predictable results and efficient use of resources. Inattentiveness often results in reactive efforts, limited potential and triage.
