APFISN Workshop on Transboundary Cases of Forest Invasive Species Management

APFISN Workshop on

Transboundary Cases of Forest Invasive Species Management 

22 -24 February

During

Asia-Pacific Forestry Week

Clark Freeport Zone, Pampanga, Philippines


Background

The management of forest invasive species (FIS) can be challenging due to the following factors:

  1. difficulties and delays with their detection (especially at early stages of introductions),
  2. the diversity of organisms from microbes to trees that become invasive,
  3. the inability to forecast invasion and to mount timely intervention strategies and
  4. the limited resources available for the task at hand.

Inter-country collaborative efforts in pest monitoring and surveillance are paramount for the successful management of transboundary invasive species. Furthermore sharing of information on efforts to manage FIS is of prime importance to avoid repeating mistakes and to implement the appropriate measures in a timely fashion. The management of an FIS also requires an understanding of the species behaviour in its original habitats and the natural enemy complex associated with the species there. A practical approach to facilitate such collaboration is to initiate invasive species research and management programmes involving multiple countries to aid seamless sharing of experiences and adoption of successful workable practices.

The proposed workshop to be conducted in conjunction with the Asia-Pacific Forestry Week in the Philippines in February 2016 will focus on facilitating capacity building in implementation of inexpensive pest monitoring systems, enhancing collaboration among FIS researchers and practitioners from multiple countries (by sharing information on ongoing and past efforts to manage FIS) and identifying common transboundary issues. The workshop will involve practical application of ground based insect pest monitoring methods, detailed deliberations on the lessons learned from the ongoing transboundary projects on surveillance and management of FIS and identification of implementable small scale FIS projects based on the ground activities.

Objectives

  1. Sharing experiences from the transboundary project on Polyphagous Shot Hole Borer (PSHB).
  2. Transfer of knowledge and capacity building for foresters on inexpensive pest trapping and ground based monitoring methods
  3. Sharing of experiences from the FAO Technical Cooperation Programme (TCP) project on the management of tropical FIS with special reference to invasive trees and preparation of guidelines for management
  4. Identification of common FIS problems of interest and prospective small scale and regional projects on transboundary FIS

Project brief

1. Transboundary project on Polyphagous Shot Hole Borer (PSHB)

The Polyphagous Shot Hole Borer (PSHB), Euwallacea sp., became a major concern in California during 2012 when the fungus it vectors started to cause die-back of the Avocado. . Polyphagous Shot Hole Borer has impacted ornamental trees and avocado production areas in Israel and Acacia sp. trees in Viet Nam. In China, the PSHB has impacted the critically listed species, Acer buergerianum, but little information is known about the impact of this species in these areas.

APFISN, Beijing Office organized a China-Vietnam-United States Cross Border Field Study on PSHB, supported by USDA Forest Service, Food and Agricultural Organization (FAO), State Forestry Administration of China (SFA), Vietnamese Academy of Forest Sciences and the Institute of Zoology, Chinese Academy of Sciences in April 2015. The main objectives of this work is to determine the beetle’s life cycle, to contribute to taxonomic studies for PSHB and its fungal complex, survey for biological control candidates, and assess the impact of PSHB-FD on tree species and current management options.

2. TCP project on Control & Management of destructive tropical FIS

The TCP project simultaneously implemented in India and Maldives has established model sites in both countries to assess the economic and ecological impact of FIS, development of species specific and landscape specific management methods and to devise modes of ensuring community participation in FIS management. The targeted invasive species in India were Senna spectabilis, Mikania micarantha and Acacia mearnsii and in Maldives, the focus was on control of Lanatana camara and mikania micarantha. In India, the project developed strategies to prevent flowering of senna trees to arrest its reproduction to prevent its further spread. The methods were implemented successfully at the landscape level paving way for the restoration of indigenous flora, in an area where the displacement of the native herbivore population had disrupted the natural food web leading to increased human-wildlife conflicts.

Expected Outputs

  1. Documentation of State-of-Art of the current status of knowledge on Polyphagous Shot Hole Borer in the Asia-Pacific region.
  2. List of areas for capacity building for implementation of inexpensive ground based surveillance for detection of transboundary FIS.
  3. Documentation of key Tree invasions in the Asia-Pacific region and protocols for management.
  4. List of prospective regional multi-country projects and key FIS of common interest.
  5. Action plan for APFISN for the year 2016-17.
