Germinación de semillas de seis especies de Bursera del centro de México

Este artículo evaluó la influencia de la temperatura y el almacenamiento en la germinación de seis especies de Bursera nativas a México (B. bicolor, B. bipinnata, B. cipallifera, B. fagaroides, B. glabrifolia, B. grandifolia). Encontraron alta proporciones de semillas vanas en tres especies. Había un aumento en la germinación dentro de condiciones con una temperatura fluctuante (32-18 °C) en comparación con las semillas expuestos a una temperatura constante (25 °C). No hubo diferencias significativas en la germinación entre las especies con semillas almacenadas durante seis meses a temperatura ambiente y en refrigeración (25 °C). Después de cuatro meses, la germinación de Bursera glabrifolia, B. copallifera y B. bicolor fue del 30 a 60%.

Putting Participatory Domestication into Practice in West and Central Africa

backgroud

This article reviews the process of participatory community tree domestication in central Africa.

Research Goals & Methods

In case studies examined, nurseries were planned in coordination between the International Center for Agroforestry Research and local communities, and the two groups divided the funding and supply of nursery materials. No salaries were paid to the farmers working in the nursery. ICRAF staff trained community members in propagation techniques.

Feasibility of Farmer-Managed Vegetative Propagation Nurseries in Cameroon

background

This article reviews farmer-managed vegetative propagation nurseries in Cameroon. The authors summarize the division of costs required to establish and operate the nurseries.

Research Goals & Methods

Cuttings of Dacryodes edulis, Irvingia gabonensis and Ricinodendron heudelotti were studied. All had successful rates of propagation by cutting, but only Dacryodes edulis had success with air layering.

Reforestation in the Philippines, Proceedings from the Fourth Pacific Science Congress, Java

  • This Bureau of Forestry authored document describes reforestation efforts to recover areas degraded by shifting agriculture. A forest nursery was established in 1910 to determine best forest tree species for “artificial reforestation of cogon lands” and in areas of “second growth of no commercial importance”- 600 species were experimented with.

Annual report of the director of forestry of the Philippine Islands for the period 1907-1913

background

This report contains a number of sections relevant to early reforestation activities in the Philippines, including research on succession pathways, restoration experiments on degraded lands, tree nursery operations, and native species.

conclusion & takeaways

This report provides the rare opportunity to look at the history of forestry and ecological activities in the tropics. These activities and projects can now be analyzed in the full context of the past 100 years, wherein the arcs of their success, failure, and learnings can be more fully understood.

Reforestation project using native species in Maringa-Lopori-Wamba region (Democratic Republic of Congo): establishment of the Bonobo Peace Forest.CDM-AR-PDD

Background

Bonobos are endemic to the forests of the Democratic Republic of Congo and are at a high risk of extinction. Specifically, the UN has drawn attention to the speed at which infrustructure growth is infringing on bonobo habitat. Thus, it developed a program to halt these trends and conserve the bonobos.
