Sustainable ranching and restoring forests in agricultural landscapes, PanamaBackgroundConventional cattle ranching in Panama has led to significant ecological issues, including loss of biodiversity, soil degradation, decreased ecosystem services, and more. This article highlights the experiences of Asociación de Productores Pecuarios y Agro-silvopastoriles de Pedasí (APASPE), a local cattle ranching association pioneering sustainable cattle ranching techniques, along with the capacity building and financial support provided by the Environmental Leadership and Training Initiatives (ELTI) based at Yale University.

Increasing local capacities in rural PanamaBackgroundWhile Panama continues to have high levels of biodiversity, the country loss large swaths of forest between 1950 to 2000 primarily due to the expansion and intensification of cattle ranching. Drawing from their work with local ranchers, the authors review the emergence of cattle ranching in Panama along with potential solutions and unique approaches to halting these trends.

Crecimiento Comparativo de Especies Nativas y Teca plantadas en parcelas puras y mixEspañolantecedentesEl interés por la reforestación como una alternativa a la deforestación se ha incrementado en los últimos años en Panamá. Sin embargo, en las iniciativas de reforestación las exigencias de las plantas no son usualmente consideradas y las mas utilizadas son especies introducidas. Open access copy available |
A tree-based approach to biomass estimation from remote sensing data in a tropical agricultural landscapebackgroundDue to increased global dominance of agricultural lands in the tropics, methods to establish biomass and carbon in agricultural areas are necessary for monitoring and modeling global C stocks. Since tropical agriculture often includes some tree cover, the study seeks to develop above ground biomass estimates using landscape-scale surveys with LiDAR in comparison to plot-level data.

Changing gears during succession: shifting functional strategies in young tropical secondary forestsBackgroundAdaptations toresource availability strongly shape patterns of community composition along successional gradients in environmental conditions. This study examines the extent to which variation in functional composition explains shifts in trait-based functional strategies in young tropical secondary forests during the most dynamic stage of succession (0–20 years).

Foliar herbivory and leaf traits of five native tree species in a young plantation of Central PanamaBackgroundTimber plantations often provide economic incentives for land owners to restore abandoned pastures or agricultural land to forest, yet the threat of insect herbivory can diminish these new plantations and compromise the efforts. This study seeks to understand the extent of these threats on tree plantations in Panama. Open access copy available |
Changes in vegetation structure and composition along a tropical forest chronosequence: implications for wildlifeBackgroundChanges in tropical forest structure and species composition that occur during regeneration following land abandonment may have important consequences for wildlife populations. Many animals rely on forest resources as sites for foraging, nesting, and protection that may vary in abundance in forests of different ages. This study examines aspects of forest composition and structure thought to be important to wildlife along a tropical moist forest chronosequence in the Barro Colorado Nature Monument of central Panama.

Neotropical Secondary Forest Succession: Changes in Structural and Functional CharacteristicsBackgroundThis paper reiviews the main biotic and abiotic factors that influence patterns of secondary forest succession in the Neotropics after complete forest clearance due to human activities. Research Goals & MethodsThe authors look at patterns of species replacement and various processes that occur during succession and suggest that the sequence of processes may be predictable even if species composition is not.

ANCON, ANARAP, CCIAP: PanamaEspañolAntecedentesPara el 2014, Panamá había perdido mas del 65% de sus áreas forestales, con una tasa anual de deforestación de mas de 20 mil hectáreas. Hasta el 2009, esfuerzos de restauración forestal solo habían logrado regenerar aproximadamente 75 mil hectáreas, correspondiendo a 14% de lo destruido. La economía de Panamá es altamente dependiente de bosques y servicios forestales por lo cual es imprescindible la restauración sostenible de las areas restantes. Open access copy available |
