One potential hyperaccumulator plant in Papua New Guinea that could be used for mine rehabilitation to remediate polluted water and land is the Alyxia buxifolia, also known as the Sea Boxwood.
This plant has been found to have a high tolerance for heavy metals and can absorb and accumulate these pollutants in its tissues, making it an effective natural remediation tool for contaminated environments. Alyxia buxifolia has been used successfully in other countries for phytoremediation purposes and could potentially be a viable option for mine rehabilitation in Papua New Guinea.
What are other plants grass type used in highland region mining area that will grow for 5years or more
1. Guinea grass (Panicum maximum): Guinea grass is a popular choice for mine rehabilitation in highland regions due to its ability to grow in diverse soil conditions and its tolerance to heavy metals. It can also provide erosion control and stabilize soil in mining areas.
2. Rhodes grass (Chloris ana): Rhodes grass is a perennial grass species that is well-suited for highland mining areas due to its drought tolerance and ability to thrive in poor soil conditions. It can help improve soil fertility and prevent soil erosion in degraded landscapes.
3. Bahia grass (Paspalum notatum): Bahia grass is a tough and resilient grass species that can tolerate acidic soils and high levels of heavy metals. It is known for its ability to establish quickly and provide ground cover in mining areas.
4. Kikuyu grass (etum clandestinum): Kikuyu grass is a fast-growing and vigorous grass species that can spread rapidly and form a dense ground cover in highland mining areas. It is drought-tolerant and can help stabilize soil and prevent erosion.
5. Ruzizi grass (Andropogon distachyos): Ruzizi grass is a perennial grass species that is well-adapted to highland regions and can thrive in disturbed environments such as mining areas. It has a strong root system that can help improve soil structure and prevent soil erosion over time.
