Barriers to Forest Regeneration of Deforested and Abandoned Land in Panama

Background

This article presents research findings on the effect of four limiting factors on tree regeneration: competition with the exotic grass Saccharum spontanaeum, seed dispersal limitation, fire, and soil nutrient deficiency.

Research Goals & Methods

Treatments included prescribed grass cutting and burning, as well as the placement of plots at different distances from adjacent forest.

Natural History, Seed Predation, and Germination of Prosopis juliflora Relative to a Reforestation Project in Southwestern Ecuador

background

This article provides information on the natural history of Prosopis juliflora in Ecuador and describes the efforts to use this native species in reforestation of tropical dry forest in the Proyecto Eduardo Aspiazu Estrata project.

Research Goals & Methods

Over 200 sacks of pods (around 15-20 kg) of seeds were collected in March-May 1994 and examined at the seed bank.

Propagating Framework Trees to Restore Seasonally Dry Tropical Forest in Northern Thailand

background

One issue of concern in native species reforestation is the lack of information on propagation and nursery practices of native seeds and seedlings.

Research Goals & Methods

This research presents data on the germination and performance of ten native species that were formerly classified as possible "framework" species to be used in reforestation in northern Thailand.

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.

Enrichment Planting of Dipterocarps in Logged-Over Secondary Forests: Effect of Width, Direction and Maintenance Method of Planting Line on Selected Shorea Species

background

In this study, three different planting design experiements were conducted using three Dipterocarp tree species planted in a heavily logged area of South Kalimantan. The area was logged in 1979 and used for shifting cultivation until 1988.

Reforestation of Abandoned Pastures: Seed Ecology of Native Species and Production of Indigenous Plant Material

background

This book chapter provides important considerations for sustainable native species reforestation efforts. The authors suggest that although using native species is more prevalent than ever before, there has been little attention to the provenance of the trees used and the genetic diversity within species.

Growth analysis of nine multipurpose woody legumes native from southern Mexico

Background

Deforestation in Mexico has produced significant soil degradation. Reforestation with native leguminous shrubs and trees can contribute to restoration of soil properties. This study evaluates early growth of nine leguminous tree and shrub species in nursery conditions in an ejido (communal agricultural land) in southern Mexico.

Tropical Forest Restoration: Tree Islands As Recruitment Foci In Degraded Lands Of Honduras

Background

Methods to accelerate forest recovery must address a number of impediments including limits on seed dispersal and microclimactic extremes. This study evaluates the ability of tree islands to serve as recruitment foci for additional seeds in a two-year study in northern Honduras.
