Write Back continuation, if not the increase, in population reduction of resident geese by US Department of Agriculture and US Fish and Wildlife Service officials. Resident â and now migratory â geese, as well as many other species of resident and migratory birds, continue to pose major threats to aircraft. Research on, and management of, these species must continue, to minimize the probability of bird collisions with aircraft in the future.

Can Field Nat 121: 313â20. doi:10.1890/09.WB.026 In response to Pauchard et al.âs review, Ainât no mountain high enough: plant invasions reaching new elevations (Front Ecol Environ; doi:10.1890/080072; published online on 31 Oct 2008 via Frontiers e-View, at www.frontiersinecology.org), mountain ecosystems throughout the world are undoubtedly facing an alarming and accelerating risk of plant invasions. The authors have correctly concluded that a cost-effective opportunity to study and manage such invasions simultaneously is now available. At present, most alien biota in these fragile ecosystems remain confined to lower elevations, but will most likely ascend to higher elevations with increasing human disturbance and global climate change. Thus, it would be advisable to initiate a research and policy framework on plant invasions in mountains, similar to that organized under the Mountain Invasive Research Network (MIREN). However, MIREN currently has no representative sites within Africa and Asia. We believe that the results generated from networks like MIREN can substantially contribute to global policy formulation only when there is genuine worldwide representation. Given the huge ecological and economic stakes involved with invasions (Pimental et al. 2005), there is an urgent need to study plant invasions in the montane ecosystems of the developing world. Montane ecosystems in China and India, Asiaâs two fastest globalizing economies, are facing a grave threat from bioinvasions (Khuroo et al. 2007; Lin et al. 2007). Recently in these countries, increasing human activities in montane landscapes (eg highway/railway construction, interlinking of rivers, tourism, and urbanization) have not only led to the destruction and degradation of natural ecosystems, but are also abetting the intentional and/or unintentional introduction, establishment, and spread of invasive alien species. With global warming, invasive species, which were previously restricted to the lower altitudes, are now ascending to the Himalayan highlands (Khuroo et al. 2007). With increasing international trade, China and India may also serve as potential recipients and donors of invasive alien species with their trading partners. Biological invasions do not recognize political borders. This is a global problem, and necessitates global research efforts and policy responses (Rashid et al. 2009). The perennial scarcity of scientific information in the developing world has been a major impediment when devising global environmental policy and management plans. Therefore, in the present globalized world, it will be highly cost effective to initiate invasion studies in montane ecosystems â in both the developed and developing world â at the same time.
