ABSTRACT

Resumen La cordillera del Kutukú está ubicada al sureste de Ecuador y se encuentra parcialmente aislada de la cordillera de los Andes. Realizamos cinco expediciones a este macizo, donde obtuvimos de manera directa información referente a la riqueza de aves. Además, con el fin de generar un listado más completo, realizamos una recopilación de registros publicados y revisamos colecciones de museos ecuatorianos. En total registramos 501 especies de aves, en un rango entre 500 - 2300 m de altitud. Encontramos trece especies con nuevas ampliaciones de distribución altitudinal y/o latitudinal. Veintiséis especies de aves (5.2%) están en alguna categoría de amenaza a su conservación, a nivel mundial y nacional. Las escasas vías de acceso, sumadas a las políticas de ingreso al territorio, por parte de la etnia Shuar, han favorecido la preservación de los bosques, especialmente aquellos por encima de los 1800 m. Es así que, el conocimiento biológico de esta área queda aún por descubrir. Esta zona remota protege una importante diversidad, así como poblaciones de aves amenazadas, recursos hídricos, además del territorio y cultura de las comunidades que la habitan. Desafortunadamente la totalidad de la cordillera se encuentra concesionada para exploraciones de proyectos mineros. Por tanto, se requiere la atención de las autoridades regionales y nacionales para aunar esfuerzos que aseguren su conservación y exploración biológica.


Abstract The cordillera del Kutukú is located in the southeastern Ecuador and is partially isolated from the Andes mountain range. We conducted five field expeditions to the region, where we directly obtained information regarding the richness of birds. In addition, we compile bird richness data from published records and Ecuadorian museum's collections in order to provide an updated list. A total of 501 bird species were registered, in an elevation range from 500 to 2.300 m a.s.l. We found 13 species with new latitudinal and/or longitudinal distribution extensions. Twenty-six species (5.2%) are in an elevated risk category nationally or globally. The region's limited roads, added to the Shuar ethnic group policies for entering to their territory has aided in the conservation of forests, especially those over 1800 m a.s.l. Thus, the biological knowledge of this area remains to be discovered. This remote area protects an important diversity, as well as threatened bird populations, water resources, territory and culture of the indigenous groups that inhabit it. However, unfortunately the entire mountain range is under concession for exploration of mining projects. Therefore, the attention of regional and national authorities is required to join efforts to ensure their conservation and biological exploration.

ABSTRACT

Understanding the trans-boundary deforestation history and patterns in protected areas along the Belize-Guatemala border is of regional and global importance. To assess deforestation history and patterns in our study area along a section of the Belize-Guatemala border, we incorporated multi-temporal deforestation rate analysis and spatial metrics with survey results. This multi-faceted approach provides spatial analysis with relevant insights from local stakeholders to better understand historic deforestation dynamics, spatial characteristics and human perspectives regarding the underlying causes thereof. During the study period 1991-2014, forest cover declined in Belize's protected areas: Vaca Forest Reserve 97.88%-87.62%, Chiquibul National Park 99.36%-92.12%, Caracol Archeological Reserve 99.47%-78.10% and Colombia River Forest Reserve 89.22%-78.38% respectively. A comparison of deforestation rates and spatial metrics indices indicated that between time periods 1991-1995 and 2012-2014 deforestation and fragmentation increased in protected areas. The major underlying causes, drivers, impacts, and barriers to bi-national collaboration and solutions of deforestation along the Belize-Guatemala border were identified by community leaders and stakeholders. The Mann-Whitney U test identified significant differences between leaders and stakeholders regarding the ranking of challenges faced by management organizations in the Maya Mountain Massif, except for the lack of assessment and quantification of deforestation (LD, SH: 18.67, 23.25, U = 148, p > 0.05). The survey results indicated that failure to integrate buffer communities, coordinate among managing organizations and establish strong bi-national collaboration has resulted in continued ecological and environmental degradation. The information provided by this research should aid managing organizations in their continued aim to implement effective deforestation mitigation strategies.
