Abstract:
1. An encasement device for planting mangrove seedlings or propagules comprising a transparent or translucent body having a generally cylindrical shape having transparent or translucent body wall with an upper end and a lower end; a single longitudinal slit through the body wall forming opposing slit wall edges contiguous to each other between the upper end and the lower end; two longitudinal grooves parallel to one another along an interior wall of the body wall, each of the longitudinal grooves and the longitudinal slit being approximately 120 degrees apart from one another, wherein an angular force due to plant growth and development directed outward against the interior wall by an increase in cross-sectional area of the developing plant causes a proportional outward movement of the body wall in a radial plane pivoting at the longitudinal grooves to affect an opening of the encasement device at the longitudinal slit and at the longitudinal grooves which results in an increase in displacement of the encasement.
