What are typical materials used in tree support systems?

Tree support systems are designed to provide stability to trees that may be structurally compromised or require additional support due to environmental factors, growth patterns, or other circumstances. The correct answer highlights that cables and bolts are commonly used materials in these systems.

Cables are typically employed to help stabilize branches and trunks, offering support to prevent splitting or breaking during strong winds or heavy loads, such as ice or snow accumulation. They can help redistribute forces acting on the tree and reduce the risk of failure. Bolts may be used to connect different parts of the tree or to attach support devices securely, ensuring that the system remains rigid and effective.

Using cables and bolts provides a versatile and adjustable solution for various tree species and growth conditions, allowing for custom support tailored to the specific needs of each tree. This technique is critical for maintaining the health and durability of trees while minimizing potential hazards to nearby structures and people.

The other options include materials that do not serve the primary function of support in this context. Wood and concrete, while potentially useful in certain construction contexts, do not typically constitute the flexible and dynamic solutions needed for tree support. Plastic and metal only limits the discussion to materials that might not adequately provide the necessary strength and adjustability found with cables and bolts. Lastly,
