Description of Workshop:

Natural processes have been restoring natural disturbances since the beginning of time.  This full day workshop will explore how these natural processes can be applied to the restoration of sites that humans have disturbed.  It is clear that traditional reclamation treatments are failing to generate the ecological goods and services that were lost during the disturbance of the site.  This workshop will look at how disturbed sites can be re-integrated with the natural successional processes that operate to create productive, self-sustaining ecosystems.  We will look at common filters or constraints to recovery – erosion, compaction, low nutrients, lack of propagules, herbivory, etc. and how natural systems solve these problems.  We will explore methods of applying these solutions to anthropogenic disturbances often at a fraction of the cost of traditional reclamation treatments.  Soil bioengineering techniques for the treatment of steep and/or unstable sites as well as riparian areas will be presented.  The course will include a brief overview of monitoring and maintenance strategies.  A course manual is provided.
