Adequately storing exceptional species requires specialized expertise, infrastructure, and greater resources than conventional seed storage....
    • Conservation assessment of Guaiacum sanctum and Guaiacum coulteri: Historic distribution and future trends in Mexico

      López-Toledo, Leonel; Gonzalez-Salazar, C.; Burslem, D.F.R.P.; Martinez-Ramos, M. (2011)
      Guaiacum sanctum and Guaiacum coulteri are long‐lived Mesoamerican timber tree species heavily exploited throughout their range and considered to be at risk of extinction. Both species are included on the IUCN Red List and on CITES Appendix II, but there has been no formal assessment of the conservation status of either species. We used ecological niche modeling and rapid assessments of local density and population size structure to provide such evaluations....
    • Ecological and socio-economic factors influencing aguaje (Mauritia flexuosa) resource management in two indigenous communities in the Peruvian Amazon

      Horn, Christa M.; Gilmore, Michael P.; Endress, Bryan A. (2012)
      In this study, we sought to better understand the social, economic, and ecological factors influencing the development of sustainable management practices for Mauritia flexuosa (aguaje) in two Maijuna indigenous communities. Focus groups, semi-structured interviews and household surveys were conducted to document current and historical patterns of aguaje harvest and management, the importance of aguaje to household income, and to identify current harvesting strategies and key perceptions regarding management….

      Give your reintroduced population a good chance for survival by starting with adequate numbers of plants or seeds at the beginning. Determine the source of the plants or seeds. Determine whether the source should consist of seeds or plants from a single population or from mixed populations.
