Background: The tropical rain forest (TRF) has been transformed by the land use change. Coffee plantations are part of the landscape, and their abandonment can favor the original vegetation regeneration. Hypothesis: The abandoned coffee plantations protection in TRF favors natural regeneration, allowing the development of secondary forests in diffe...
Aim of the study: To evaluate how middle-aged active restoration plantations of native tree species contribute to the recovery of the tropical cloud forest in terms of vegetation structure, tree richness, species composition, and to shade-tolerance and seed dispersal mode functional groups.
Area of the study: We studied two 19-year-old active rest...
El trabajo se enfoca en la revisión bibliografía de estudios recopilados sobre huertos familiares, solares o traspatios realizados en el estado de Veracruz
que registran la biodiversidad, su manejo y el conocimiento que los propietarios tienen particularmente sobre las especies y el agroecosistema
huerto. Interesa conocer qué tanto se sabe sobre lo...
El enriquecimiento de los bosques manejados es una práctica que implica la inserción de especies de valor cultural, económico y ecológico. Son sistemas que han sido históricamente modificados y manejados por el hombre para favorecer una sola especie. Ejemplo de ello son los cachichinales, bosquecillos típicos de la región Sierra de Misantla, en el...
Los huertos familiares han sido y todavía son ampliamente estudiados, tanto en México como en otras regiones del mundo. Sin embargo, los huertos son aún poco entendidos en su complejidad. Si bien disciplinas como la agroecología, la agroforestería, la etnobotánica e incluso la adopción de métodos de la antropología han contribuido favorablemente a...
Se presenta el trabajo realizado por el Cuerpo Académico “Ecología Aplicada al Manejo de Ecosistemas Forestales” (CA-UVER 246) en torno al tema de la degradación forestal. Se exponen los fundamentos teóricos, métodos y aplicaciones partir de una selección de casos de estudio realizados en colaboración con nuestros estudiantes de la Universidad Vera...
An important part of ecological restoration is the periodic evaluation of its success.
The objective was to evaluate restoration success in the short and medium term of
cloud forest restoration trails established since 1998 around Xalapa, Veracruz. Plantings
of native tree species with pioneer, intermediate and late successional tree species
were e...
Restoration practices assist in the reversal of ecological degradation of forest remnants and deforested areas. The enormous biodiversity in the cloud forests of central Veracruz, Mexico, poses a challenge to its restoration. The objectives of this study were to determine the ecological restoration potential of native tree species, and to define cr...
This chapter presents results of a scenario-building exercise, designed to explore future trends in forest biodiversity in four forest areas, and the potential implications for policy develop-ment and implementation. An expert consultation conducted in a workshop environment identified 11 principal pressures responsible for biodiversity loss in Lat...
Temperate and tropical montane forests in Latin America represent a major natural resource at both regional and national levels for a number of reasons – biological, climatic, economic, cultural. Native tree species in these forests share conservation problems because of deforestation, habitat degradation, overall biodiversity loss and integrity of...

Las plantaciones mixtas de Carpinus caroliniana y Liquidambar styraciflua son apropiadas para rehabilitar áreas deforestadas en la región del bosque de niebla en Veracruz, México. Para determinar si la siembra directa de semilla puede usarse en actividades de restauración ecológica, se estudiaron algunas condiciones abióticas y bióticas para la ger...
Four native tree species (Liquidambar styraciflua, Juglans pyriformis, Podocarpus matudae, and Carpinus caroliniana) were evaluated for their suitability in rehabilitating degraded areas of Mexican cloud forest. Plant survival and growth in height and diameter were determined in three mixed-experimental plantations with different land use histories...
This work succinctly revises the role of the dead wood in the conservation of the biodiversity and the performance of the ecosystem, especially to nutrients and water cycling. Likewise, some factors that decrease the amount of dead wood in the forest ecosystems, the steps to minimize the impact of these factors and some agreements and rules on this...
