“…The increased community AGB might result in positive impacts on the impaired ecosystem because the vegetation plays a key role in maintaining the soils in which they grow (Liu et al 2010). The increased litter falls resulting from increased community AGB can improve the soil chemical properties and physical structure, and increase the biological activities within the soil (Mishra et al 2003, Liu et al 2010.…”

In order to restore the impaired forest ecosystem in China, great efforts including the banning of the animal grazing and cutting woods for fuel, and implementation of the ‘Grain for Green’ program have been made by the central and local government of China. The objective of this research was to investigate the changes in above-ground biomass and species diversity after 22 years of vegetation recovery efforts in the lower Taihang Mountain of China. The results indicated that over the natural restoration process shrubs became the dominant species in 2008, while herbs were the dominant species back in 1986. Community coverage, height and above-ground biomass showed significant increases in 2008 compared to 1986. Shrubs showed significant increases in coverage, height, and above-ground biomass, whereas herbs significantly increased in height, but decreased in above-ground biomass. Over the 22-year natural restoration process, the species richness index and the Shannon-Wiener’s index had been significantly decreased, whereas the Simpson’s predominance index and the Pielou’s evenness index had been significantly increased. Long-term vegetation recovery efforts improved the impaired forest ecosystem in lower Taihang Mountain to some extent: significant increases in both community coverage and above-ground biomass. The significant increase in community coverage can reduce the soil loss by wind and water erosion, and increase in the above-ground biomass will improve the soil chemical properties and physical structure. A comprehensive assessment of the success of vegetation recovery should include the evaluation of the changes in ecological process such as soil biological activities in the future research.

“…This is attributed to the degree of neutralisation of the soil exchange complex (Rhoades and Binkley, 1996). Biological soil acidification under forest ecosystems has been previously reported in the tropics: in Argentina (Jobbagy and Jackson, 2003), in India (Misra et al, 2003) and in Brazil (Lilienfein et al, 2000). Comparing a natural forest and five common plantation species including a eucalypt and a pine, Michelsen et al (1996) revealed a higher nutrient content under natural forest and attribute this to the loss of organic matter during conversion of natural forest to plantations, increased leaching in young plantations, and low nutrient demand by natural forest trees as compared with fast growing exotics.…”

“…Plantations' establishment on former pastures may also have prevented the regeneration of more environmentally valuable natural forests, although regeneration would have depended on several factors such as distance to sources of propagules or intensity of site degradation. By contrast, plantations may have favored or accelerated the regeneration or afforestation of native species in some places, notably by attracting agents of seed dispersal and improving local soil and microclimatic conditions [92][93][94]. It has been estimated that 10% of total natural regeneration in Costa Rica has occurred on previous plantations over 1987-2013 [88].…”

International market forces have played an increasingly important role in shaping land use dynamics through complex supply chains. In Costa Rica, the shift from a net loss to a net gain in forest cover was facilitated by forest plantations and the replacement of extensive cropland and pastures by export-oriented, high-yielding crops. However, agricultural intensification generated several feedbacks affecting forests. We analyzed the interactions between Costa Rica's agricultural and forestry sectors associated with the use of wood pallets for commodity exports over 1985-2013. Wood pallets for growing agricultural exports created a demand for domestic tree plantations. The annual land demand for tree plantations to produce these wood pallets increased by 669%, reaching 17,606 ha in 2013 and representing 28% of the increase in demand for cropland for agricultural exports over 1994-2013. Wood supplied from plantations failed to fully substitute for wood from natural forests, only allowing for a relative substitution and preventing a major sparing of these forests. The dominant use of wood from plantations for production of low-value pallets de-incentivized investments in sustainable plantations. We showed that, beyond the typical interactions between agriculture and forestry through direct competition for land, international trade generated unexpected feedback where agricultural activities and supply chains affected forestry by triggering new demand and profound changes in forestry management. Land systems behave as complex systems, calling for integrated approaches to study the outcomes of forest conservation, reforestation programs, and development of land-based businesses.
