Manage Terrestrial Species

Each geographic and ecological setting is unique and may require the use of different methods to ensure appropriate, effective, and permitted control measures. The information provided below lists eight general steps to guide terrestrial invasive plant management efforts in the Adirondack region. The Adirondack Park Invasive Plant Program (APIPP) developed guidelines for landowners on how to manage the most common terrestrial invasive plants. Additional management information is included in the profiles of each Species of Concern.

Step 1: Set Yourself Up for Success

Step 2: Determine if Herbicide Use is Necessary

  • Herbicide may be required to manage large infestations or species with an extensive rhizome system.
  • Research basic herbicide use information.
  • Landowners may only apply herbicides to their own property.
  • For all herbicide applications, the product label is the law and should be followed accordingly.
  • Wear the proper personal protective equipment (PPE) as specified on the product label.

Step 3: Determine Permitting Requirements

Step 4: Determine Project Feasibility & Set Realistic Goals or Outcomes

  • Early detection and rapid response is crucial for an invasive plant management project to be successful. As an invasive species infestation increases in size, it gets progressively more difficult and expensive to control. For large infestations, complete elimination is often impossible.
  • APIPP strongly recommends that large scale projects be run through The Nature Conservancy’s Invasive Plant Management Decision Analysis Tool (IPMDAT) before implementation.

Step 6: Monitor Your Results

  • For projects aimed at complete elimination, annual follow-up treatments of any regrowth is often required. Management sites should be visited annually for at least five years after the initial treatment or until no invasive plants have been documented at the site for at least three consecutive years
  • To document the effectiveness of your management, you can map the extent of the site each year to record declines in acreage or percent cover.
  • Photo documentation is also beneficial in showing invasive plant declines and native plant recovery over time.
  • Standard monitoring plots can be established to document invasive plant declines and native plant recovery over time.
  • Field Data Sheet for Invasive Species Monitoring

Step 7: Adapt As Necessary

  • In many instances you will need to adapt your management strategy or goals based on the results of your monitoring efforts. For example, you may need to adopt a stronger management tool such as an herbicide after manual management efforts have failed. Additionally,  you may need to switch from an elimination strategy, to containment or suppression strategy after several years of failed elimination efforts.
