Espoirs, perspectives et propositions pour une reforestation en Haïti
… solutions pour engager le pays sur la voie de la reforestation doivent traiter le problème globalement et tenir compte des conditions de succès mises en lumière dans cet essai. La principale recommandation est de lancer un vaste chantier national de reforestation avec la participation de tous les …

Reforestation Management to Prevent Ecosystem Collapse in Stochastic Deforestation
… study is motivated by the need to understand the reforestation management in secondary forests to prevent irreversible ecosystem damage. We begin by setting the drift and volatility in stochastic primary forests. However, it is more manageable to take control of replantation. We employ a dynamic …

Investigating the efficiency of reforestation approaches in restoring rainforest biodiversity and function
Ecological restoration is being increasingly applied to reverse or mitigate biodiversity losses, re-instate ecological functions and increase the provision of ecosystem services in tropical forests. Effective assessment of the success of ecological restoration projects is critical in justifying the …

Herbaceous and woody plant establishment across hydrologic gradients in bottomland reforestation sites
Flooding is an important determinant of plant establishment, as well as planted tree survival and growth, in restored floodplain forests. Thus, community assembly in a restored floodplain and, ultimately, restoration outcomes are likely constrained by the site’s hydrologic regime, along with other …

Hydroseeding pine-grass-legume mixtures for erosion control and reforestation of mine spoils
Growth and mycorhizal colonization of surface-seeded pine (Pinus spp.) as affected by two mine-spoil types (siltstone and sandstone), two fertilizer levels (control and 100 kg/ha each of N, P, and K), and three mycorrhizal inoculation treatments (control, 56 kg/ha pine litter, and 250g/ha …

Appalachian Surface Mine Reforestation Techniques: Effects of Grading, Cultural Treatments and Species Selection
… Ha of mixed mesophytic forest. Successful reforestation would be beneficial, but questions remain concerning application of reclamation and reforestation methods on operational scales. Four experiments were performed testing these methods on newly reclaimed and previously reclaimed, but …

Patterns, Processes And Models Of Microbial Recovery In A Chronosequence Following Reforestation Of Reclaimed Mine Soils
… to changes or impairment of ecosystem functions. Reforestation procedures were designed to accelerate the reestablishment of plant community and the recovery of the forest ecosystem after reclamation. However, the microbial recovery during reforestation has not been well studied even though this …

Costs of Reclamation on Southern Appalachian Coal Mines: A cost-effectiveness analysis for reforestation versus hayland/pasture reclamation
The two most common options for post-mining land uses in the southern Appalachians are forestry or hayland/pasture. Hayland/pasture has become the predominant reclamation type due to ease of establishment and strict regulation standards requiring quick and dense erosion control by herbaceous cover. …

Improving domestic markets for the wood products of reforestation programs: a case study of eucalyptus in northwestern Senegal
There is a drastic need for reforestation in the Sahel region of Africa. International donors and local governments invest large sums of money for the purpose of planting trees. Unfortunately, the majority of reforestation efforts last only as long as the projects. Presently there is a push in the …

Human ecological analysis of land and forest use by the Hmong people for harmonising with the governmental reforestation program in Vietnam
… the Government of Vietnam has launched reforestation programs aiming to increase the forest cover of the country and to improve the living of local population. In this context, conflicts between the state and local people over land and forest have been entailed or even intensified. To be …

Mitigating Investment Risks in Nature-Based Solutions: A Strategic Approach Towards Sustainable Project Implementation
Reforestation plays a crucial role in combating global warming while promoting biodiversity conservation and restoring ecosystems. However, poorly planned reforestation efforts can lead to increased emissions and long-term damage to landscapes, biodiversity, and livelihoods. In addition, low carbon …

Socioeconomic processes of land degradation in Guadalajara province (Spain)
… of soil and water conservation projects through reforestation would be effected. The reforestation agencies of the Government could have improved the effectiveness of conservation by acknowledging and dealing with the need to study the socioeconomic processes of land degradation and involve …

Carbon storage during the regrowth and conversion of Virginia Piedmont forests
… upon amounts of erosional loss prior to reforestation. The forested land area in the southeastern United States has stabilized, and forest conversion is now the primary form of reforestation. Therefore, the region's ability to continue to store carbon has been questioned. Still, the …

Development of Ecosystem Structure and Function on Reforested Surface-Mined Lands
… coalfield disturbs landscapes. Post-mining reforestation efforts now achieve successful reestablishment and growth; however, it is unclear whether reforestation efforts also restore the native forest ecosystem functions. We quantified rates of return of key ecosystem functions and structural …

Restoring forest landscapes for nature conservation and human well-being: Advanced spatial decision support tools
… GIS-based multicriteria methodology to identify reforestation priorities, to design a number of landscape-scale reforestation options and to assess them according to their socio-ecological performance. The prioritisation was based on two main non-compensatory factors: the need for biodiversity …

Persistence potential of Great Basin high-elevation conifers under novel climates and disturbance regimes
… for ongoing natural regeneration and future reforestation interventions. Using observational and experimental approaches, I 1) characterized the natural regeneration niche for each species, 2) identified advantageous seedling traits and assessed evidence for local adaptation and plasticity …

Soil productivity model to assess forest site quality on reclaimed surface mines
… Presently, the standard for evaluating reforestation success is based solely on tree-seedling survival. This method is an estimator of stand density and not an indication of site productivity. There exists a need to evaluate mine soils based on their capability of growing merchantable …

Evaluation of forest site potential in the Northwest Department of the Republic of Haiti
In August, 1976 a cooperative reforestation program between Virginia Polytechnic Institute and State University and the Haitian-American Community Help Organization was initiated in the Northwest Department of the Republic of Haiti. A network of forest tree nurseries was established in the …
