Secures Landscape Plant Plugs, Preventing Displacement Due to Environmental Forces
This vegetation anchoring device secures plants used for coastal restoration projects. Coastal wetlands and shorelines provide important ecological services, including storm protection, improved water quality, and habitat for wildlife. However, erosion, storm activity, and rising sea levels are degrading many of these environments, increasing the need for effective coastal restoration strategies. The global coastal protection systems market size reached $18 billion USD in 2024 and is expected to reach $46 billion USD by 2033, with a compound aggregate growth rate of 12.60%. Coastal restoration projects often involve planting vegetation using landscape plugs, which are small, containerized plants with established roots that are easy to transport and plant in large quantities. Existing erosion control methods can help stabilize shorelines, but they are not designed to hold individual plant plugs. Additionally, currents and sediment movement can dislodge newly planted vegetation in coastal environments before roots have fully developed. There is a need for anchoring devices specifically designed to withstand harsh coastal environmental conditions.
Researchers at the University of Florida are developing a carrier for plants to help secure and anchor vegetation used in coastal restoration. The device is designed specifically to hold landscape plant plugs in place in coastal substrates where traditional stakes or containers are ineffective due to soft sediments and harsh environmental conditions.
Application
Anchors plant plugs in place, reducing the risk of displacing newly planted vegetation used in coastal restoration and shoreline stabilization projects
Advantages
- Keeps newly planted vegetation in place, enabling root systems to establish themselves in the surrounding substrate
- Includes openings for water circulation, supporting root growth into the surrounding sediment
- Designed for installation without specialized equipment, enabling manual deployment in restoration sites
- Manufactured using biodegradable material, ensuring the anchors do not persist in the aquatic environment
Technology
The system uses three primary components—a perforated basket, a thread cap, and an insertion spike—function together to secure a landscape plant plug in coastal substrates. The perforated basket holds the plant plug and its growing medium while allowing water movement and root growth through the surrounding openings. The threaded cap then attaches to the basket and secures the plug in position, enabling it to remain stable during environmental exposure. Finally, extending from the bottom of the basket is an insertion spike that penetrates the coastal substrate and anchors the device in place. The anchor is required only during the time the plant establishes a root system; therefore, the anchors are produced using biodegradable materials to ensure they do not persist in the aquatic environment. The device gradually breaks down after the vegetation becomes established.
