Development of tools to estimate the contribution of young sweet chestnut plantations to climate-change mitigation

Investigations of the spatial and climate characteristics of natural pure chestnut (Castanea sativa Mill.) forests: A case of Zonguldak Regional Directorate of Forestry

“…In addition, the increase in chestnut forests and afforestation also provides benefits in terms of slowing down global climate change. Menéndez-Miguélez et al, (2023) in a study they conducted, aimed to calculate the above-and belowground biomass of chestnut plantations. Thus, they aimed to calculate the carbon sequestration role of young chestnut areas using the models they developed.…”

Effects of the Abandonment of Traditional Cultural Practices on Epiphytic Bryolichenic Communities in Chestnut Orchards in North-West Spain

“…(2) temperature (1 for bryophytes in cold conditions found in high mountains, 3 for cool conditions, 5 for fairly warm conditions, 7 for warm conditions, 9 for extremely warm conditions, and Ind for indifferent bryophytes); (3) moisture (1 for bryophytes of extremely dry sites, 3 for bryophytes found more often in dry sites than moist sites, 5 for those of moist sites, 7 for moist sites, 9 for wet sites, and Ind for indifferent bryophytes); (4) pH of the substratum (1 for bryophytes on extremely acid substrata, 3 for those on acid substrata, 5 for those on moderately acid substrata, 7 for those on weakly acid to weakly basic substrata, 9 for those on basic substrata, and Ind for bryophytes indifferent to pH); ( 5) eutrophication (1 for bryophytes of sites with very weak eutrophication, 3 for those of weak eutrophication, 5 for those of medium eutrophication, 7 for those of high eutrophication, and 9 for where no bryophytes occur); (6) human influence (1 absent, 3 weak, 5 moderate, 7 strong, and 9 very strong); (7) forest type (1 for bryophytes largely restricted to closed forest, 1.2 for bryophytes that prefer forest edges, 2.1 for bryophytes that occur both in forest and open land, and 2.2 for bryophytes that may occur in forest but prefer open land) (Table S4). For ecological requirements (1) to (6), intermediate states between those previously described received intermediate (even) numbers.…”

“…Chestnut forests are concentrated in countries close to the Mediterranean Basin, occupying large areas in Italy, France, Spain, Portugal, Greece, and Turkey [3,4]. In Spain, the chestnut is distributed over an area of 272,400 ha, of which 154,500 ha are pure [7]. In Galicia (NW Spain), chestnut trees cover more than 49,300 ha [8].…”

“…Traditional sweet chestnut management involves the organisation of grafted trees in two types of monospecific systems with different stand densities: orchards or open stands, where the main product is the fruit, and coppiced forests regenerated from adventitious or dormant buds, where the main product is the wood [11]. Both systems are interesting examples of socio-ecological production landscapes [13,14] as they are an important source of timber, firewood, and chestnut fruit, but also of other goods and services, such as honey, agroforestry pasture, litter for fertilisation or mulching [12,15], climate regulation through carbon storage [7], erosion control and water purification, and high biodiversity [16][17][18][19][20].…”
