Restoration of a Coastal Swamp Forest in Southeast Brazil

background

This study evaluates the potential for nine native tree and shrub species for use in the revegetation of degraded swamps in Rio de Janeiro, Brazil.

Research Goals & Methods

Invasive grasses and other vegetation, including the exotic tree Casuarina equisetifolia were removed from the site.

Conclusions & Takeaways

Taller seedlings resulted in higher survival rates for those species with higher survival rates. Myrsine rubra, Tabebuia cassinoides, andCalyptranthes brasiliensis showed high growth and survival rates, and are recommended for use in revegetation programs. A shorter duration of flooding was generally beneficial for seedling survival and this effect can be enhanced by planting in mounds. The addition of organic matter had a positive effect on growth for all species studied, but with less variation among species than the other factors. The authors suggest that by planting in mounds, adding organic matter, and planting mixtures of high performing species, the revegetation and ecosystem restoration of these swamp forests can be feasible.
