Memorias del I Congreso Colombiano de Restauración Ecológica

Background

These proceedings summarize the 11 Master Conferences at the "I Congreso Colombiano de Restauración Ecológica y II Simposio de Nacional de Experiencias en Restauración" in 2009. It includes information from dozens of forest restoration projects in Colombia. Most projects are restoration experiements with native species forest restoration in the montane zone of Colombia, although some reports describe projects in lowland humid forest, dry forest, and high mountain páramo.

Efecto de la zona de vida y la altitud en la mortalidad y adaptabilidad al primer año de especies forestales en la Cordillera Volcánica Central de Costa Rica

Español

Antecedentes

El entendimiento comprensivo de la restauración de bosques requiere de la comprensión del fenómeno de la mortalidad incluyendo su magnitud y ubicación espacial. En Costa Rica, no existe suficiente información capturando los efectos de climas pluviales sobre la mortalidad de especies forestales, especialmente en zonas altas.

Evaluation of Native Tree Species for the Rehabilitation of Deforested Areas in a Mexican Cloud Forest

background

This study examines the survival of four native tree species used in mixed-experimental plantations in the tropical montane forest of Veracruz, Mexico (1300-1900m). Tropical montane covers only 1% of land surface in Mexico but contains ~ 10% of all flowering plants. In Veracruz, forest fragments occupy on 10% of the oringinal forest cover.

Dominant Species’ Resprout Biomass Dynamics After Cutting in the Sudanian Savanna-Woodlands of West Africa: Long Term Effects of Annual Early Fire and Grazing

BACKGROUND

This study examines the potential for forest regeneration after harvest in Burkina Faso, West Africa. The study area is a tropical dry forest of tree-shrub dominated by trees of Combretaceae and Mimosaceae (Fabeaceae). The area is part of the Sudanian savanna ecoregion, stretching across Africa , and receives approximately 700-1200 mm of rain, interspersed by a 6-7 month dry season. Firewood is the major source of home energy. It is estimated that 25-50% of the forest area naturally burns each year, and all areas burn every 2-3 years. Cattle browsing is also common in the region, especially on the grass that sprouts after burns.

The Role of Revegetation for Rehabilitation of Sodic soils in Semiarid Subtropical Forest, India

background

This study relies on a  case study evaluate the rehabilitation of barren land within a larger forest ecosystem. The article indicates that restoration opportunities exist even with severely degraded land where natural succession does not occur without management practices.
