Local ecological knowledge of trees on farms, constraints and opportunities for further integratino in Tigray Region, northern Ethiopia: A Case Study of smallholder farmers in Abreha Wa Atsbeha and Adi GudomBackgroundThe paper compared two Ethiopian sites with differing levels of on-farm tree adoption: Abreha we Atsbeha (high adoption) and Adi Gudom (low adoption). The author used a knowledge-based systems approach involving participatory rural appraisal, focus group discussions, and semi-structured interviews. In both sites, farmers planted trees on their holdings for income generation, user rights, and direct benefits, and they planted trees on communal lands to comply with government policies, improve soil fertility and water harvesting, improve land for redistribution, and improve aesthetics.

Direct seeding to restore rainforest species: Microsite effects on the early establishment and growth of rainforest tree seedlings on degraded land in the wet tropics of AustraliaBackgroundIn Queensland, Australia, three degraded sites (a high elevation site, mid elevation site and low elevation site) that were dominated by non-native grass were studied. The study looked at how six different methods of sowing affected the establishment and growth of small and large seeds, as well as how it affected weeds growth and re-establishment. Before the sowing treatments were conducted, the weeds, since it often outcompetes seeds/seedlings, were removed using herbicides. The sowing treatments created microsites that either consisted of the seeds being buried beneath the soil or placed above the soil. Available with subscription or purchase |

China’s Conversion of Cropland to Forest Program for Household Delivery of Ecosystem Services: How Important is a Local Implementation Regime to Survival Rate Outcomes?BackgroundIn response to catastrophic droughts in the lat 1990s, China launched one of the largest afforestation-based Payments for Ecosystem Services (PES) progrms. Much research around this program has focused on the impact on rural welfare. This study, on the other hand, examines the tree survival rates during the “Grain for Green” Program based on socio-economic data of the single households. Open access copy available |

Forest and landscape restoration severely constrained by a lack of attention to the quantity and quality of tree seed: Insights from a global surveybackgroundThis review article focuses on tree seed supply in the context of forest and landscape restoration (FLR). The article asserts that large-scale FLR commitments will require billions of tree seeds and seedlings, and that this supply is extremely inadequate in terms of not only quantity but also genetic diversity and quality. The article reviews 139 FLR projects worldwide and identifies widespread problems in the availability and diversity of tree seed supply. Open access copy available |
