- Abstract
Extensive knowledge has accumulated on the subject of invasive plant species in Israel in recent years; however, management experience in treating current invasions is scarce, and in many cases has only had partial success. We believe that the absence of a structured plan for decision-making and implementation is one of the main weaknesses that prevents a more efficient and successful treatment of invasive plant species. This paper reviews the project established to contain the spread of Acacia saligna in the Judean Mountains National Park and, for the first time, presents a plan for long-term active management to treat invasive plants on a large regional scale. In the current project, the main objective is to protect local natural resources, landscape and heritage from invasion and domination by the invasive plant A. saligna. In order to bridge knowledge gaps in the lead-up to active management, the region was mapped to characterize the distribution and density of A. saligna. At the same time, a pilot study was conducted to determine the cost and efficacy of different management options and field conditions for implementation. The basis for implementation was that the action plan be practical and feasible. Implementation began in January 2018 and consisted of two stages: cutting down mature trees and treating the stumps in the frst year, followed by regular treatment of regenerating shoots, rootstocks and seedlings. The project was monitored and results demonstrated the significant effectiveness of cutting down trees and treating the stumps, for killing the mature trees and regenerating vegetation in the treated plots. To examine the effectiveness of the project in containing the invasive species, monitoring was conducted on isolated groups of trees in the area that served as an untreated control. Preliminary results demonstrated that in the absence of treatment, A. saligna continued to spread, probably due to pine thinning treatment. Regeneration measurements in treated plots compared to control plots indicated that the project was highly effective in containing the spread of the invasive species – the main objective of this project. Collaboration between the bodies that set policy and those that manage open landscapes proved to be a catalyst for achieving the target. The project has demonstrated that an action plan based on ecological knowledge and professional understanding, forms the basis for success in the battle against invasive plants.
