Geographic Variation in Tree Growth and Wood Density of Guazuma crinita Mart. in the Peruvian Amazon

background

This research addresses intra-specific variation in the native Peruvian tree species Guazuma crinita, a fast-growing pioneer species and priority timber tree used in reforestation and agroforestry systems. It also evaluates the tree growth and wood density of G. crinita varieties from 11 provenances in the Peruvian Amazon.

Responses of 20 Native Tree Species to Reforestation Strategies for Abandoned Farmland in Panama

Background

In the tropics, deforestation often leads to unproductive agriculture and results in degraded grasslands. This study seeks to understand why forests fail to regenerate naturally in these ecosystems.

Soil organic matter dynamics during 80 years of reforestation of tropical pastures

Background

Land disturbance affects soil physical and chemical properties. Some properties may be recovered over long periods of reforestation. Mosaic-pattern landscapes with shifting usages over time, common in the mountainous tropics, can reveal dynamic soil properties. This study reports on changes in soil carbon over 80 years of secondary forest growth on abandoned pasture over a chronosequence in Puerto Rico.
