Growth analysis of nine multipurpose woody legumes native from southern MexicoBackgroundDeforestation 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.

Direct Seeding to Restore Tropical Mature-Forest Species in Areas of Slash-and-Burn AgriculturebackgroundDirect seeding of three mature-forest species into areas of slash-and-burn agriculture was conducted to evaluate the germination and establishment of these species. Research Goals & MethodsDifferent fallow times were evaluated, less than 5 years, 8-15 years, and greater than 50 years. Germination, survival, and growth for 1-2 years was evaluated for 1800 seeds planted per species (200 on each of three replicate sites per forest age). Open access copy available |
Restoration of former grazing lands in the highlands of Laos using direct seeding of four native tree species: Seedling establishment and growth performanceBackgroundDirect seeding has recently regained favor as a lower-cost alternative to planting seedlings for restoration of degraded or abandoned sites. This study reports the establishment and growth performance of 2 pioneer (Pinus kesiya and Schima wallichii) and 2 later-successional (Keteleeria everlyniana and Quercus serrata) native trees broadcasted or buried on former grazing lands in Laos.

Natural History, Seed Predation, and Germination of Prosopis juliflora Relative to a Reforestation Project in Southwestern EcuadorbackgroundThis 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 & MethodsOver 200 sacks of pods (around 15-20 kg) of seeds were collected in March-May 1994 and examined at the seed bank. Open access copy available |

Dalbergia Sissoo Mortality in Bangladesh Plantations: Correlations with Environmental and Management ParametersbackgroundThis research seeks to correlate environmental and plantation conditions with the widespread mortality of Dalbergia sissoo trees planted in Bangladesh. Goals & MethodsIn order to understand the relationship between D. sissoo mortality and environmental and plantation characteristics, the authors examined 72 mixed plantations across five districts in Bangladesh.

Initial Performance and Reforestation Potential of 24 Tropical Tree Species Planted Across a Precipitation Gradient in the Republic of PanamabackgroundThe authors of this study planted trees from 22 native species and two exotic species to use in selection trials testing the growth and survivability of trees in plantations in three different sites. Research Goals & MethodsThe sites were chosen for their precipitation gradient from Soberania National Park (2226mm mean annual rainfall), Los Santos (1946mm rainfall), and Rio Hato (1107mm rainfall). Survival, basal diameter, height, crown diameter and wood volume index (VI) were calculated after two years of growth. Available with subscription or purchase |
Rehabilitating Degraded Forest Land in Central Vietnam with Mixed Native Species PlantingsBackgroundThis study considers the imepdiments to reforestation presented by grasses such as Imperata cylindrica. It specifically examined the use of Acacia as a nurse crop to overcome some of the ecological and economic impediments to reforestation of degraded areas dominated by grasses.
