Hakalau Forest National Wildlife Refuge Comprehensive Conservation Plan Immediate Threats to Hawaiian Forest Birds at Hakalau Forest NWR Feral Ungulates (24 votes) Lack of Habitat (21) Invasive Plants (12 votes) Predation (7 votes) Data Insufficient to meet Management Needs (8 votes) Parasites (2 votes) Interspecific Competition (1 vote) Avian Disease (no votes were received, so removed from list) The focus on October 9 was identifying and prioritizing major management actions and research necessary to recover the forest birds found at the Refuge. These management actions and research (collectively, activities) were also ranked using a multi-voting technique as follows: Management Actions (Priority Ranked by Voting) 1) *Grazers/browsers (Habitat destruction/mosquito production) – High (overall 24 votes) • Fence construction, maintenance, and removal of animals (combined total = 30 votes) • See Research Priorities 2) Habitat Restoration – High (21 votes) • Revegetation of pasture land (15 votes) • Improve ‘ohi‘a densities (7 votes) 3) Invasive plants – High (overall 12 votes) • Continue invasive species control (blackberry, banana poka, gorse) (11 votes) • Prevent and eliminate incipient weeds (2 votes) • See Research Priorities 4) Monitoring and Data Needs – High (overall 8 votes) • See Research priorities • Delivery of technical information (2 votes) 5) Predation – Medium (overall 7 votes) • See Research priorities 6) Parasites – Low (overall 2 votes) • Incipient invasive parasites, true population counts, de-louse birds (2 votes) 7) Interspecific competition – Low (overall 1 vote) • See Research priorities • Identify ectoparasites/mites E-6 Appendix E. Forest Bird Workshop Report
Hakalau Forest National Wildlife Refuge Comprehensive Conservation Plan Research Priorities (Priority Ranked by Voting) 1) Monitoring and Data: Expand point counts/banding data – 15 votes (combined primary counter training (8 votes), consider use of a B-Bird (Breeding Biology Research and Monitoring Database) system (http://www.umt.edu/bbird/info.htm) (7 votes), and threat surveillance (1 vote)) 2) Predation: Investigate effects of rats on forest birds (9 votes); rodent population index (2 votes) – 11 votes 3) Invasive Plants: Develop effective biocontrols – 8 votes 4)*Grazers/Browsers: Predator proof fencing – 7 votes 5) Invasive Plants: Develop more efficient control methods and registration of herbicides – 4 votes 5) Determine the effects of global climate change at the Refuge – 4 votes 6) Develop more effective cat control techniques – 2 votes 6) Determine effects of ectoparasites on non-endangered bird populations – 2 votes 7) Experimental control of Japanese white-eyes – 1 vote *Caveat: Activities to construct an ungulate proof fence and a predator-proof fence caused some confusion amongst the participants. Dr. Scott obtained consensus that these activities could be combined with a third separate but related activity of removing feral ungulates. Conclusion: A workshop evaluation was distributed to all participants on October 24, 2008. Of the 37 participants, 11 provided evaluations (= respondents). A number of Service employees, as organizers of the workshop and authors of this summary, did not provide written evaluations, so the response rate is actually higher than it initially appears. A summary of the evaluations is attached as Appendix A. In short, however, findings of the evaluations were: Overall the perception of the workshop organization and format was entirely positive. However, some respondents felt the workshop purpose and objectives fluctuated too much in advance of the workshop, were unclear, or were known but unstated. While this was in part a result of ‘adaptive management’ of the agenda and a deliberative process by the steering committee, more, earlier input from potential participants would help address this criticism for future workshops. The presentations themselves were largely felt to be very informative and address the workshop purpose and objectives, given the previously mentioned concerns about those objectives. The amount of time allotted to presentations was generally thought adequate, and the facilitation by Dr. J. Michael Scott very good. Appendix E. Forest Bird Workshop Report E-7
