Novel ecosystems - where biotic and/or abiotic changes have led to systems that have no-analog in the present or past - are a worldwide phenomenon. Myriad interacting environmental changes and thresholds to restoration prevent return to some
historical state. What should restoration ecologists do when confronted by such systems? One answer may be to restore function to them. In this seminar, Mike will introduce the concept of novel ecosystems and show their global importance in the
21st Century. He will argue that they are a necessary consideration for restoration ecology. He will then introduce the Ridgefield Multiple Ecosystem Services Experiment, which shows a potential path for restoration management in novel ecosystems while also providing a valuable test of ecological theory. Ridgefield, in the
highly fragmented agricultural landscape of south-west Western Australia, investigates how species composition and diversity (through variation in the plant traits within the system) influence the provision of multiple valued ecosystem functions including carbon sequestration, nutrient cycling and resistance to non-native invaders. He will share some early results from this recently planted long-term experiment, showing how differences in survival may affect the long-term provision of, and trade-offs among, ecosystem services.
