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.

Cloning of erect, thornless, non-browsed nitrogen fixing trees of Haiti's principal fuelwood species (Prosopis juliflora)

Background

Prosopis juliflora (bayawon in Creole) is a spiny leguminous tree that is used throughout arid regions of Africa, Asia, and the Caribbean for fuelwood and fodder.  Due to its genetic diversity, pod protein and carbohydrate content varies widely, suggesting advantages of clonal reproduction. This Haiti-based study tests exotic and native varieties of Prosopis for growth rates.

Linking Multiple-Level Tree Traits with Biomass Accumulation in Native Tree Species used for Reforestation in Panama

background

This research presents the links between biomass accumulation, plant traits, and functional groups for five native species in abandoned pasture of central Panama.

Tropical Forestry Practices for Carbon Sequestration

Background

Carbon sequestration through forestry has the potential to play a significant role in ameliorating global environmental problems such as atmospheric accumulation of greenhouse gases and climate change. This chapter provides an overview of various aspects related to carbon sequestration through forestry.

Survival and Growth of Under-Planted Trees: A Meta-Analysis Across four Biomes

background

This article is a meta-analysis synthesizing the results of survival and growth of under-planted trees in forests in tropical, temperate coastal, boreal, and temperate deciduous forests. Additionally, the survival and growth of these underplanted trees are evaluated according to the silvicultural treatment affecting density of the overstory: uncut, dense shelterwood, intermediate density shelterwood, light density shelterwood, clear cut.

Root architecture and allocation patterns of eight native tropical species with different successional status used in open-grown mixed plantations in Panama

Background

While an increasing number of native tropical trees are under study for reforestation and commercial plantations, the majority of studies on trees in the tropics have concentrated on the aboveground aspects of tree growth. This study investigates biomass allocation and root architecture of eight tropical species with different successional status.

Species-Rich but Distinct Arbuscular Mycorrhizal Communities in Reforestation Plots on Degraded Pastures and in Neighboring Pristine Tropical Mountain Rain Forest

background

This study compares the arbuscular mycorrhizal fungi (AMF) of 4 native species saplings growing in three types of fire-degraded pasture (recently abandoned, bracken covered, and shrub covered pasture) to the AMF richness and composition of 30 adult tree species in neighboring primary forest.

Selecting framework tree species for restoring seasonally dry tropical forests in northern Thailand based on field performance

Background

Framework tree species are indigenous forest tree species, planted to complement and accelerate natural regeneration of forest ecosystems and encourage biodiversity recovery, on degraded sites. This study tests the extent to which 37 native forest tree species might act as framework tree species to accelerate recovery of evergreen, seasonal forest in a degraded upper watershed in Doi Suthep-Pui National Park in northern Thailand.

Seedling survival and growth of native tree species in pastures: Implications for dry tropical forest rehabilitation in central Panama

Background

Enrichment planting of tree seedlings is a method for accelerating reforestation of pastures in Central America. Persistent presence of cattle can be an impediment to the survival of unprotected seedlings, although cattle may also be a source of nutrients. Grasses can also cause competitive pressure on newly planted seedlings.

Forest Carbon Project in the Quirino Provience, Philippines

Background

Over a 7 year span from 2003 to 2010, Conservation International Phillipines and ICRAF have conducted studies and developed initiatives to address carbon sequestration in the Sierra Madre Biodiversity Corridor region, which is a 1.4 million hectare forested region that is critical for biodiversity, hydrology, and other ecosystem services.

Ulu Masen REDD+ initiative, Aceh, Indonesia

Background

The area of the Ulu Masen Conservation Area has been degraded due to an illegal logging boom after the tsunami as well as increasing agricultural expansion. The Ulu Masen REDD+ initiative was developed by the Government of Aceh (GoA) to address these issues.

Can Native Tree Species Plantations in Panama Compete with Teak Plantations? An Economic Estimation

background

Panama has high rates of primary forest conversion, resulting in depleted timber resources. In response, the timber plantation industry is growing to meet demand, often with non-native species. This study compares the economic feasibility of using native tree species vs non-native species for plantation forestry.

Seed germination of Loxopterygium guasango, a threatened tree of coastal Northwestern South America

background

Loxopterygium guasango is a tree native to Ecuador with threatened status as of 1993, despite its durable wood, history of timber use, and potential use in reforestation. This study reports on seed germination, a potential cause of its low regeneration rates.

Seedling survivorship, growth, and response to disturbance in Belizean mangal

Background

Species zonation patterns across tidal gradients in mangrove forests are formed by successful seedling establishment and maintained by replacement of adults by conspecific seedlings. These two processes have rarely been examined experimentally in neotropical mangrove. This study examines survivorship and growth of seedlings of Rhizopora mangle and Avicennia germinans across a tidal gradient in Belize.
