PUBLIC TALK: The Value of Seagrasses in the Restoration and Recovery of Oceans
|The Value of Seagrasses in the Restoration and Recovery of Oceans
A public lecture by Professor Gary Kendrick and Dr John Statton, UWA Oceans Institute.
Seagrass meadows are among the most highly valued ecosystems on earth, worth $34 000 ha-1 yr-1 as they protect our coastlines, clean our polluted waters, capture atmospheric carbon are habitat for fish and feed many coastal communities of the world. We are losing seagrass meadows at rates comparable to those for coral reefs globally. An estimated one quarter of the world’s seagrass meadows is already lost. How do we turn about this loss? The main tools of an applied scientist are removing the drivers of loss and to enhance recovery through rehabilitation and restoration.
At the UWA Oceans Institute, and in collaboration with industry partners, we are developing large scale restoration techniques that can be used to both restore seagrasses and to enhance existing seagrass meadows for sustainability. To achieve large-scale restoration of degraded seagrass meadows, we take a lessons learnt approach from terrestrial restoration practices and apply this within a marine setting. Our research focuses on four key areas: seed harvesting and seed sowing, seed dormancy and germination, seedling growth and survival, and genetics to assess adaptability to environmental change. In this lecture we will present our gardening secrets for growing seagrasses for restoration.
About this Series: All at Sea - Restoration and Recovery
Our oceans and coasts provide us with food, energy, livelihoods, cultural and recreational opportunities, yet they are coming under increasing pressure. This UWA Institute of Advanced Studies Oceans Institute Lecture Series explores the wonders of our seas, the challenges they face and how research at UWA - in a diverse range of fields including marine science, ocean engineering, health, humanities and social sciences are contributing to ensure sustainability.
