Successful afforestation has been practiced in South Africa for more than a century. Recently, however, problems with afforestation of pines have occurred in the northeastern part of the Eastern Cape Province. Rapid mortality of Pinus patula and P. elliottii have occurred when small container seedlings were planted on old-agricultural soils. Death would often occur within 5 months of planting. ...

Concentrations of cellulose, lignin and nutrients in the stemwood of four clones of 7-year-old hybrid aspen (Populus tremula L. x P. tremuloides Michx.) were studied on 50 permanent experimental plots established for the afforestation of abandoned agricultural lands in Estonia. Quantitative evaluation of hybrid aspen chemical components indicated a relatively high cellulose and low acid-insolub...

for the successful tree establishment, an evaluation of land suitability is necessary.in this paper, we demonstrate how to implement fuzzy classification of land suitability in agis environment for afforestation with juglans regia in gharnaveh watershed of golestanprovince in iran. juglans regia is one of the most important agro-forestry species in manyrural parts of iran. relevant criteria for...

Large-scale irrigated afforestation of sub-tropical deserts; reduced-impact logging (RIL) of fallen trees in ‘virgin’ tropical forests; and managed ocean macroalgal afforestation of ocean ‘deserts’ have been proposed [1, 2, 3] as techniques to sequester more CO2 than has been dumped into the atmosphere, by the burning of fossil fuels and by deforestation, since the beginning of the industrial r...

-To compare methods for bottomland hardwood reforestation on marginal farmlands in the Mississippi Alluvial Valley, four afforestation treatments (natural colonization, sown oak acorns, planted oak seedlings, cottonwood–oak interplant) were established in 1995 on former soybean cropland. Natural, sown, and planted-oak plots were not managed after establishment. Interplant plots received intensi...

In context of Bonn Challenge commitment, Pakistan (Khyber Pukhtunkhwa) has implemented forest restoration and afforestation on 0.35 million hectares between 2015–2017. Billion Tree Afforestation Project (BTAP) is an initiative mass to meet the commitment. The current study a pilot evaluate success plantation activities by assessment regeneration, growth performance survival rate plantations rai...

wild almond (amygdalus scoparia) is one of the most important species that provides a variety of ecological functions in the zagros forest ecosystem. in this study, we investigated the effects of some seed treatments on the survival and growth of amygdalus scoparia after seed planting at different aspects and elevations under natural conditions. the seed pretreatments consisted in soaking them ...
