Burning and grazing in a bunchgrass paramo ecosystem: Vegetation dynamics described by a tranisition model
A simulation model is proposed, describing vegetation dynamics in a bunchgrass paramo ecosystem, in relation to cattle grazing and burning. Field-work was conducted in Parque Nacional Natural Los Nevados, Colombia, at elevations of 3900-4200m. Three successive stages of vegetation development are recognised in relation to grazing: an opening phase of the bunchgrass layer, conditionally followed...
Aspects of human influence on upper-Andean forest line vegetation
A dense Andean forest at 3400-3750m elevation, dominated by Weinmannia mariquitae and Miconia spp. in the Colombia Parque Nacional Natural Los Nevados was studied with aerial photographs and vegetation releves. Five main land use types were distinguished: intact upper-Andean forest, upper-Andean forest with selective cutting, the "socola" system, pasture with scattered trees, and total clearings...
Return to the heart of the world
This is an account of a flying expedition in the Colombian mountains of the Sierra Nevada De Santa Marta.
Spiritual significance and environmental effects of offerings amongst the indigenous people of the Sierra Nevada de Santa Maria
The Sierra Nevada de Santa Marta is the highest coastal mountain range in the world and covers an area of 17,000 square kilometres. Its population includes some 32,000 members of the Kogi, Arhuaco, Wiwa and Kankuarno indigenous groups, descendants of the Tayronas and preservers of their ancient traditions. There are also approximately 150,000 peasants, and 1.5 million urban dwellers in the...
Proceso para cuantificar e interpretar las características físicas y químicas del suelo que reglan su función en relación con el agua, el almacenamiento de nutrientes y la infiltración (Caso de la cuenca de la laguna de Fúquene)

Process to measure and interpret physical and chemical characteristics that regulate soil behaviour in relation to water, nutrient storage and infiltration: Case of the Fuquene Lake.

The Fúquene river basin is located in the central part of Colombia near the city of Bogotá and has an area of 187,000 hectares. This watershed was selected because the lake is suffering...

Protecting the 'Heart of the World'

To the Kogi Indians of the Sierra Nevada de Santa Marta, in Colombia, the Sierra is 'the heart of the world'. One man is at the centre of effort to restore that heart to good health.

The Kogi Indians believe the Sierra moves between good and evil, between day and night, between south and north, searching for equilibrium, says Juan Mayr, founder and director of the...

Paramos: A checklist of plant diversity, geographical distribution and botanical literature

A comprehensive work on the páramo plant diversity is now available in a checklist form. The need of this type of publication is increasingly acknowledged by the growing number of professionals interested in biodiversity. Despite its clearly aligned botanical audience, the book can serve to a greater readership because it touches the páramos from different aspects....

Networking and rural development through sustainable forest management: Frameworks for pluralistic approaches

The sustainability of rural development initiatives (including forestry) depends greatly on the capacities of the institutions involved, the relationships among them and their relative power. Therefore a strategy to foster pluralistic approaches to rural development should focus on building the capacities of those who have typically been marginalized by development strategies and discussions...
