In order to overcome the deficiencies in existing replanting techniques, Encased Replanting was developed as a more productive and adaptable alternative to current techniques. The method focuses on isolating the seedling into a controlled environment at the actual replanting site. The encasement artificially creates an environment favorable to the seedling's initial development while protecting the plant long enough to become well established. The isolation physically separates the seedling from surrounding conditions that are unfavorable to early development of the tree.
The development of aerial roots is a crucial step that ensures viability of the developing tree. The aerial roots provide for the exchange of gases needed for respiration and will enable the tree to root even in mud lacking oxygen. Once aerial roots extend into the bottom they will provide adequate protection from displacement and ensure the continuing subsistence of the plant. Aerial or prop roots are a distinctive root structure of the Red Mangrove and a characteristic that makes the Encased method of planting an effective means of replenishment. 
The aerial root is the mechanism that will ultimately secure the plant making it resistant to environmental factors that would under normal conditions prohibit development at many potential replenishment sites. The support provided by the aerial roots will hold the trunk of mature trees above the mean high tide water level. Over time an intricate maze of roots will protrude from the stem and end the plant's dependence on the encasement for its survival.
