Cylindrical encasement devices and methods for planting mangrove propagules or seedlings along shorelines and non-native environments. The devices can use interior (or exterior) longitudinal grooves or thinned channels or lines of holes that hinge the device along the longitudinal axis to facilitate increases in displacement which results in acceleration of plant development and adaptation, improving survivability and reproductive maturity to establish self-sustaining mangrove trees and forests. A manufacturing enables control of the structure, color and opacity, to facilitate applications in habitat creation, restoration, shoreline stabilization, erosion control, and environmental remediation. Safe and easy removal of the device from the environment occurs without harm and damage.
