Complementing seedling planting with nucleation techniques increases forest restoration potential in areas around bauxite mining
The soil seed bank is one of the most important ecological indicators to evaluate and monitor the ecological restoration process of plant communities. We aimed to analyze the influence of two different ecological restoration techniques on the diversity and floristic composition of the soil seed bank and of standing vegetation, in two 4-year-old areas under forest restoration around bauxite mining, Southeast Brazil. A total of 30 soil samples were collected in each area (SPN—forest restoration by seedling planting in rows and nucleation techniques between planting rows and SP—forest restoration by seedling planting in rows). The samples were transported to a shade house and evaluated for 6 months, where germinated individuals were counted and identified weekly. A floristic census of shrub/tree species was conducted to assess the diversity of standing vegetation. The results indicated that the soil seed banks of the two areas are floristically similar (predominance of pioneer, herbaceous, and native origin species). The two restoration techniques did not differ in their effects on the species composition of the soil seed bank, mainly due to the restoration age. However, when analyzing the standing vegetation, 38 species were recorded in SPN, while only 20 species were in SP. This result demonstrates that nucleation techniques contributed to the increase in species diversity in SPN. We conclude that combining seedling planting in rows with nucleation techniques (topsoil transposition, direct seeding, and artificial perches) can enhance species diversity in standing vegetation, improve forest functionality, and consequently enhance the potential for forest restoration.
期刊介绍:
Land Degradation & Development is an international journal which seeks to promote rational study of the recognition, monitoring, control and rehabilitation of degradation in terrestrial environments. The journal focuses on:
- what land degradation is;
- what causes land degradation;
- the impacts of land degradation
- the scale of land degradation;
- the history, current status or future trends of land degradation;
- avoidance, mitigation and control of land degradation;
- remedial actions to rehabilitate or restore degraded land;
- sustainable land management.
