ArticleEstablishment of seed zones based on native plant species
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Since forest ecosystems constitute a complex ecosystem, the health of the ecosystem must be maintained. Seed zones are areas of relative climatic similarity, and movement of seeds within them should help minimize maladaptation. This study intends to build Korean seed zones by applying the US seed zone construction method.In the United States, winter minimum temperature and annual heat: moisture index (AH:M; aridity) were used to construct seed zones. Climate data for the entire Korean Peninsula was provided by Worldclim. Winter minimum temperature was determined as the minimum value per cell from December through February and was classified into 5°F (2.2°C) bands ranging from <-15° to >35°F (-26.1 to 1.6°C). The AH:M data is average temperature (°C) plus 15°C (to obtain positive values) divided by precipitation in meters. The AH:M map was divided into six discrete classes (<–16, 16–19, 19–21, 21–24, 24–27, >27). Korean provisional seed zones of 65 climatic zones were formed by overlapping both maps. Five native plant species were selected to test correspondence with the provisional seed zones. For Pine(Pinus Densiflora), Oak(Quercus acutissima), Oyster oak(Quercus variabilis), the winter minimum temperature of 15– 20°F and the AH:M of 19–21 and 21–24°C/m accounted for 37%, 43%, and 34%, respectively. Due to the latent habitat area of fern wood(Acer pictum subsp. mono), the Maxent AUC was 0.844, showing a high fit. The winter minimum temperature of 20–25°F and AH:M of 16–19°C/m accounted for 42%. Due to the latent habitat of hornbeam(Carpinus tschonoskii), Maxent AUC was 0.930, showing high accuracy. The winter minimum temperature of 25–30°F and AH:M of <16°C/m occupied 33%. In this study, provisional Korean seed zones were established and their association with five native plant species was identified. This study will be used to define initial seed zones and identify seed zones inhabiting similar climatic zones.

ArticleNetwork of seed collectors in the Paraíba Valley-Brazil: Collective action for local restoration and development 2022
Also available in:
No results found.The Direct Seeding method based on large quantities of seeds, increased the demand for seeds, is a virtuous process of cooperation between actors in the restoration chain, generating jobs and income for local communities (ANTONIAZZI et al., 2021). The objective of this article is to present the Vale do Paraíba Seed Collectors Network as an emerging action of environmental governance and its contributions to ecological restoration in degraded areas of the Paraíba Valley, in the State of São Paulo, Brazil. The Vale do Paraíba region is located in the Paraíba Sul River basin. The region has 2,26 thousand inhabitants and the water produced supplies two metropolitan regions: São Paulo and Rio de Janeiro. The current remaining vegetation of the Atlantic Forest shows a lot of alteration with few extensive conserved areas, which limits faunal activity (DEVIDE et al, 2014). In the region, extensive cattle raising occupies about 50% of the productive areas in most municipalities. Direct seeding is strongly recommended for pasture areas with little or no natural regeneration. Due to the characteristics of the region, the sloping land, like a sea of hills, requires the non-use of heavy agricultural implements. It is a labor intensive activity, with great opportunities to generate work and income for the community (ROCHA et al., 2020). In recent years, the network of native seed collectors in the Paraíba Valley was initiated in partnership with the Caminhos da Semente Initiative and local organizations. Only in 2020-2021 was there a restoration of 24.49 ha in four different municipalities in the Valley, using direct seeding with part of the seeds collected locally. More than 2,253 kg of seeds were collected and processed, involving 43 collectors from 12 municipalities. About 31,210 dollars were paid to collectors. At the same time, the project fostered the establishment of agroforestry systems in the collectors' family units, ensuring food security and the sustainability of the chain (REDE AGROFLORESTAL DO VALE DO PARAÍBA, 2021).

DocumentThe value of utilization and prospect of forest healing ingredients for native plants in Korea
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The perception of forests in Korea has changed with the times. In the past the perception of pursuing primary products such as wood was strong, but recently it has been changed to a way to pursue public interest values including recreation and healing. As the perspective of forest is changed, this study has purpose to examine the value and prospect of native plants, one of forest resources, as a resource for forest healing by linking them with food closely related to life. In Korea, a total of 205 Family, 1,157 Genus, 4,940 species of native plants are distributed. This is significantly higher than the UK (2,000species) or Denmark (1,500species), and when compared to the number of species per unit area, it is more valuable because it has a variety of species than of Japan or China. Antioxidant activity search is the most commonly used method to measure the functionality of native plants, and various studies are being conducted in this regard. Various native plants in Korea are used not only for medicinal purposes but also for edible purposes, and 71 family, 547 species edible plants are known. However, there are about 70 kinds of native plants that are actually distributed and edible in the market, which is only about 12.8% of the total. However, as interest in healthy food has increased recently, food ingredients using native plants are attracting attention again. Therefore, it is necessary to study for the application of food ingredients and the verification of the effect of native plants. The effects of native plants in Korea are being verified effects not only for antioxidant but also for health functionality. In the future, more diverse studies are needed to re-examine the edible value of native plants from a forest healing perspective and to spread them widely.
