ARMENTANO. T.V.; DOREN, R.F.; PLATT, W.J., and MULLINS, T., 1995. Effects of Hurricane Andrew on coastal and interior forests of southern Florida: Overview and synthesis. Journal of Coastal Research, SI No. 21, pp. 111-144. Fort Lauderdale (Florida), ISSN 0749-0208. The effects of Hurrican Andrew upn the forests of south Florida as of early 1994 are summarized from studies conducted at sites located within the track of the storm as it passed across the peninsula. Updated information on the storm's track and eyewall configuration also is provided. Effects on slash pine savannas, hardwood hammocks, cypress domes and mangroves varied markedly but with some trends apparent. Severe damage and mortality of trees was greatest in mangrove forests where 59 to 85% of trees were killed, but vigorous seedling recruitment of red mangrove and sprouting of surviving black and white mangroves is now well underway. Severe effects in cypress domes was quite low, with only 4% mortality. In slash pine stands, over 80% of the trees were damaged, and mortality pattern was related to prior condition of the stands. Mortality in large, vigorous stands ranged from 17 to 24% but approached 100% in small remnant Miami rockridge pinelands located in developed eastern coastal areas. Tropical hardwood hammocks suffered extensive damage but only averaged 11.5% mortality and regrowth has been vigorous but not necessarily of the same species characterizing the pre-storm community. Overall mortality and damage increased with tree size except in hammocks where small trees were damaged or killed by limbs and crowns of larger trees. The extensive stands of exotic tree species were damaged but recovered quickly and vigorously. The potential of the expansion into hurricane-damaged habitats is one of several long-term concerns under investigation.
Beyond Kapiti - A decade of invasive rodent eradications from New Zealand islands

New Zealand, an archipelago of more than 2000 islands, has a terrestrial fauna especially depauperate in native land mammals. Kiore (Rattus exulans) was the first of four rodent species introduced by people. A project to eradicate invasive rats from Kapiti Island in 1996, represented a turning point in the technology, complexity and scale at which managers of natural heritage on New Zealand islands could operate. This paper includes case studies of some significant projects targeting rodents, sometimes with other introduced mammals, undertaken in the 12 years following Kapiti. Details of the methods, costs, results and outcomes are provided for Kapiti, Whenua Hou, Tuhua, Campbell, Raoul, Hauturu, Taukihepa, and Pomona islands, collectively representing a total of over 23,000 ha of habitat cleared of introduced mammals. Research and trials undertaken in the Kapiti project provided the basis for future environmental risk assessments, allowing other projects to focus on knowledge gaps. New trends in invasive species eradication in New Zealand include more challenging multi-species eradication projects, some of which are undertaken by self- funded community groups. To summarise the lessons of the New Zealand experience: a programmatic approach is recommended which will fit each eradication within a context or framework of goals for those islands; address biosecurity issues at the outset; build capability to attempt the most challenging and rewarding projects; facilitate investment in monitoring and manage expectations of stakeholders to ensure their ongoing support. Success breeds success but is never guaranteed.
