We would like to thank many people (colleagues, research assistants, techniques, reviewers etc.), as well as several private and public institutions for their help during our work in America.

First of all, to Spanish public institutions which have supported and funded our research in North America at different times: The Ministry of Science and Education (Madrid) through different research programs in US, and the Universidad Complutense (Madrid) through its "Gregorio del Amo" research fund program at the University of California; the Spanish "Phytosociological Research Center" (CIF, Madrid) also supported our research by making its considerable scientific resources available to us. We would also like to thank all our colleagues at the Departamento de Biología Vegetal II (Universidad Complutense) in Madrid for their help and understanding. Of the North American Institutions we are grateful to: The US Department of Interior (National Parks Service) and the US Department of Agriculture (USDA, Forest Service) for their assistance with our field works throughout the US territories and for their help with some technical publications; the Missouri Botanical Garden (Saint Louis) gave us technical and bibliographic assistance during our stays; University of California at Davis (Departments of Environmental Horticulture and Plant Biology) offered us their resources during our stays; the UC Davis Shields Library made all its great bibliographic collections, research assistance and resources available to us ; the Davis Herbaria Society and the University of California at Berkeley helped us by giving us access to their herbaria for our taxonomic studies in the Davis Herbaria and Jepson Herbarium collections.

We would also like to thank the following individuals: Those that shared with us the research on several field trips throughout North American Boreal and Temperate territories: A. Asensi, M.G. Barbour, F. Fernández-González, M. Grandtner, M. Ladero, L. Llorens, J. Molero, J.A. Molina, G. Navarro, A. Penas, C. Reynal, P. Rodríguez-Rojo, S. Sardinero, J. Thieret and F. Valle; B. Díez Garretas, A. Asensi and F. Fernández-González ordered the phytosociological data from Alaska; S. Sardinero transferred some data on Mount Washington (New Hampshire) forest vegetation to us (Sorbo americanae-Betuletum cordifoliae); A. Penas (North America), G. Navarro (South America) and J. Giménez de Azcárate (Mexico) have collaborated in the biogeographic proposals; E. Dean (Curator of the UC Davis Herbaria), J. Shepard (UC Davis Herbaria) and the Curator of the Jepson Herbarium (Berkeley) helped us with our taxonomic research; C. Ansseau (Québec), M. G. Barbour (Davis), M. Chýtrý (Pruhonice), C. García Navarro (Davis), R.G. Gavilán (Athens), M. Grandtner (Québec), P. Rodríguez-Rojo (Davis) and F.J. Rueda (Davis) helped us with bibliographic research; S. Rivas Sáenz, A. Penas and M.A. Luengo supplied some bioclimatic data and made the adequate computer bioclimatic programs; A. Penas, J. Cortizo and I. Prieto adapted and drew the biogeographic subsectorial map of North America; J.M. Pizarro drawing the distribution maps of the phytosociological orders as well as the bioclimatic and biogeographic maps; M.G. Barbour and M.L. López Fernández made some comments, suggestions and gave us some constructive criticism about our proposals; C. Hontana carried out the computer treatment and design of our handwritten texts; and, finally, M.L. López Fernández, F. Llamas and Pru Brooke-Turner assisted us in the English version. Everybody, once again, thanks.
