Debreczy, Zsolt; Rácz, István: A re-assessment of the new taxa of firs (Abies Mill.) reported from Mexico in 1995
gional foresters based in Tulancingo in cooperation with the Division de Ciencias Forestales, Universidad Autonoma Chapingo (Enrique Guízar, pers. comm.). They found this fir in several locations in the vicinity of Metepec and Agua Bianca and are working on its in situ conservation. The habitat of Abies zapotekensis (along with the new Douglas fir population we discovered in 1994) has been protected by the local community of Santa Catarina Ixtepeji. The recently established Ecoturism Center at La Cumbre (Fig. 33) is another good sign of the conservation activity. * # * Acknowledgements - The authors are grateful for the assistance received from the local forestry and conservation authorities in Mexico including Consejo Nacional Ciencia y Tecnologia (CONACYT), Instituto Nacional de Investigaciones Forestales y Agropecuarias (INIFAP), Secretaria de Agricultura y Recursos Hidraulicos (SARH), Secretaria de Desarollo Urbana y Ecologia (SEDUE/ SEDESOL), Unidad de Conservacion y Desarollo Forestal (UCODEFO).
