    Using a replicated trial format the stakeholders compared the effectiveness of individual and combined methods of controlling invasive species in timber by using goat browsing and prescribed burning protocol. The project determined a multi-year and combined controlled methods will achieve a higher level of long-term effectiveness of invasive species in timber stands. However, even combined approaches of control will require a multi-year strategy to achieve desirable levels of control.



    The project incorporated the USDA approved methods of goat browsing and prescribed burns to maximize control of invasive species and invigorate native savanna re-growth in multi-use timber stands. An on-farm research/demonstration plot was established for comparing the effectiveness of individual and combined control methods for invasive species in timber.


    Project objectives:

    The project had 2 primary areas of targeted focus:

    1. Effective control of invasive species through use of combined control methods.
    2. Establish quality regrowth of the Oak Savanna plants and hardwoods.
