Introduction 
In 2001, the 1. Congress of Conservation of Biological and Cultural Diversity in the Andes and the Amazon Basin in Cusco, Peru, attempted to provide a platform to bridge the existing gap between Scientists, Non Governmental Organizations, Indigenous Populations and Governmental Agencies. This was followed by a 2. Congress in 2003, held in Loja, Ecuador together with the IV Ecuadorian Botanical Congress. The most important results of these conferences were published in Lyonia 6 (1/2) and 7 (1/2) 2004.

Since then, the "Andes and Amazon" Biodiversity Congress has become a respected institution, and is being held every two years in Loja, Ecuador, where it has found a permanent home at the Universidad Tecnica Particular.

In 2005, the 3. Congres on Biological and Cultural Diversity of the Andes and Amazon Basin joined efforts with the 2. Dry Forest Congress and the 5. Ecuadorian Botanical Congress, to provide an even broader venue.

The Tropical Dry Forests of Latin America as well as the Andes and the Amazon Basin represent one of the most important Biodiversity-Hotspots on Earth. At the same time, both systems face imminent dangers due to unsustainable use.
Attempts of sustainable management and conservation must integrate local communities and their traditional knowledge. Management decisions need to include the high importance of natural resources in providing building materials, food and medicines for rural as well as urbanized communities. The traditional use of forest resources, particularly of non-timber products like medicinal plants, has deep roots not only in indigenous communities, but is practiced in a wide section of society. The use of medicinal herbs is often an economically inevitable alternative to expensive western medicine. The base knowledge of this traditional use is passed from one generation to the next. Especially the medical use represents a highly dynamic, always evolving process, where new knowledge is constantly being obtained, and linked to traditional practices.
An increased emphasis is being placed en possible economic benefits especially of the medicinal use of tropical forest products instead of pure timber harvesting, an approach particularly appealing to countries with difficult economic conditions. Most research efforts, due to lack of manpower, time end resources, focus only on either biodiversity assessments or ethnobotanical inventories, or try to implement management and use measures without having a sound scientific base to do so. Often the needs of the local populations, e.g. their dependency on plant resources for health care are entirely ignored.

Lyonia presents the most important papers of these three conferences in parts of its 2005 and 2006 issues.

Resumen  Cinchona pubescens (cascarilla) posee una corteza rica en alcaloides (quinina). Fue introducida a Galápagos, específicamente en la Isla Santa Cruz en 1946. El propósito es determinar la diferencia de la cantidad de hojarasca debajo y afuera de los árboles de Cinchona, identificar la diferencia del coeficiente de descomposición debajo y determinar la línea base en la zona de Miconia para predecir un probable impacto de la Cinchona. El estudio se lo realiza desde julio del 2004 hasta octubre de 2005 en la zona húmeda de la isla Santa Cruz, a través de la recolección de la hojarasca y biomasa en trampas colocadas debajo y afuera de los árboles de cascarilla, arbustos de Miconia...

Resumen 
El presente proyecto se desarrolla en vista de la crítica situación en la que se encuentran algunas plantas endémicas de las Islas Galápagos, como es el caso de Galvezia leucantha, que esta en Peligro Crítico de Extinción de acuerdo a criterios de la Unión Internacional para la Conservación de la Naturaleza (UICN).
La obtención de protocolos de micropropagación se convierte en una herramienta para la conservación de especies en peligro crítico de extinción, ayudando así a mantener la biodiversidad única existente en las Islas Galápagos.
Se ha partido de dos tipos de explantes: yemas y segmentos de hoja sembrados en medio Murashige... [Read Entire Article]


Resumen  De las 175 especies vegetales endémicas de las Islas Galápagos 23 se encuentran en peligro crítico de extinción de acuerdo a los criterios de la UICN. Frente a esta realidad, el Parque Nacional Galápagos ha optado por la micropropagación vegetal como una estrategia para la conservación de especies endémicas. Para este trabajo se han escogido dos especies de la familia Asteracea en peligro crítico de extinción: Darwiniothamnus alternifolius y Scalesia affinis. Para el análisis estadístico se está utilizando un diseño completamente al azar (DCA) con tres observaciones. La unidad experimental para cada observación está constituida por cuatro...

Resumen 
En el Perú mediante el Decreto Supremo Nº 045-2001-PCM, se declaró de interés nacional el ordenamiento territorial ambiental en todo el país. Una de las políticas de Estado sobre la gobernabilidad está relacionada con el ordenamiento territorial, y últimamente, la Ley General del Ambiente (Nº 28611) define: "que el Ordenamiento Territorial es un proceso que contribuye al desarrollo sostenible y equilibrado del país".
Asimismo, la Comisión de la Verdad y Reconciliación para adecuar el Plan de Paz y Desarrollo, con el propósito de reconciliar el Estado con la sociedad tras veinte años de violencia, recomienda la realización de planes de ordenamiento territorial... [Read Entire Article]


Resumen  El conocimiento preciso de la cobertura vegetal de una región tiene una gran importancia no sólo en la conservación y gestión de este recurso, sino también en su utilidad como bioindicador del equilibrio ambiental de los ecosistemas. No obstante, la sobre valoración que se hace frecuentemente de su capacidad de carga y de regerenación ha generado una explotación y uso irracional, produciendo grandes impactos ambientales a nivel local y regional. En este sentido, la Teledetección ha demostrado ser una técnica especialmente adecuada para suministrar información sobre cambios producidos en la situación de ecosistemas forestales. Esto hace de dicha tecnología una herramienta con gran capacidad... [Read Entire Article]


Abstract  Restoration projects should follow four steps: identify and understand the threat; remove or reduce the threat; monitor the effect; intervene further when necessary. "Restoration" is sometimes thought of as the last of these four, but restoration may often be achieved by the first three alone. The last step implies a repeat cycle of the first three, identifying and dealing with additional threats. A first cycle usually has a community focus (for monitoring and ecological studies), whereas subsequent cycles usually imply a species focus. The Dry Zone is the most widely distributed of the Galapagos vegetation zones. It has been damaged on several islands, mainly by introduced herbivores and plants. Restoration following damage by introduced species (on which this paper focuses)... [Read Entire Article]
