April 16th, 2018 – David Polster: ‘Natural Processes for the Restoration of Drastically Disturbed Sites’

Join us for an evening with ecological restoration specialist David Polster. David will talk about his work using living plant material in reclamation techniques (such as wattle fencing) for unstable slopes – a highly relevant topic for those of use living in riparian and costal bluff areas. 
Wattle Fencing is one technique used on extremely steep, un-vegetated slopes. It is an alternative to concrete and rock retaining walls that encourages living plants to grow a bank stabilizing root mat. 
Presentation Title:
Natural Processes for the Restoration of Drastically Disturbed Sites.
Summary of the Session:
Natural processes have been restoring disturbed sites for millions of years.  By understanding how these processes operate, effective strategies for the treatment of human disturbances can be developed.  This talk will include information on how these systems can be used to treat local slumps and slides.
