Rat eradication has become a common conservation intervention in island ecosystems and its effectiveness in protecting native vertebrates is increasingly well documented. Yet, the impacts of rat eradication on plant communities remain poorly understood. Here we compare native and non-native tree and palm seedling abundance before and after eradication of invasive rats (Rattus Rattus) from Palmyra Atoll, Line Islands, Central Pacific Ocean. Overall, seedling recruitment increased for five of the six native trees species examined. While pre-eradication monitoring found no seedlings of Pisonia grandis, a dominant tree species that is important throughout the Pacific region, post-eradication monitoring documented a notable recruitment event immediately following eradication, with up to 688 individual P. grandis seedlings per 100m2 recorded one month post-eradication. Two other locally rare native trees with no observed recruitment in pre-eradication surveys had recruitment post-rat eradication. However, we also found, by five years post-eradication, a 13-fold increase in recruitment of the naturalized and range-expanding coconut palm Cocos nucifera. Our results emphasize the strong effects that a rat eradication can have on tree recruitment with expected long-term effects on canopy composition. Rat eradication released nonnative C. nucifera, likely with long-term implications for community composition, potentially necessitating future management interventions. Eradication, nevertheless, greatly benefited recruitment of native tree species. If this pattern persists over time, we expect long-term benefits for flora and fauna dependent on these native species.

This Climate Change Implementation Plan (CCIP) for the Pacific Regional Department (PARD) of the Asian Development Bank (ADB) describes the areas of focus for PARD's operations and identifies key gaps between country and ADB actions, as well as opportunities for scaling up ADB's assistance related to mitigation, adaptation and associated cross-cutting needs. This gap analysis points to recommended interventions in regional and country programs for additional technical assistance (TA) and financial assistance, including access to new climate funds and adoption of new financing mechanisms. These include multi-donor Climate Investment Funds (Clean Technology Fund and Strategic Climate Fund), ADB's Future Carbon Fund, and possibly a new Sustainable Fuel Credits mechanism to promote reduced petroleum consumption. The CCIP will evolve through periodic updates in order to effectively guide ongoing and future programs and TA and project design. Going forward, specific climate change interventions will continue to be incorporated into the Country Partnership Strategy (CPS) and Country Operations Business Plan (COBP) for each Pacific Developing Member Country (PDMC) and into the Regional Operations Business Plan (ROBP) for the Pacific region as a whole. TA and investment projects will be designed, taking into consideration regional and country variations in governance, institutional capacity, and geographic and local environmental conditions.
