      Leave Land Alone Following Natural Disasters, Say Researchers
      Despite responses to wildfires as being disasters that require human
      these natural disturbances are important ecosystem processes that
      be left alone-a move that will increase the area's recovery chances,
      a University of Alberta researcher.

      Following a forest fire, there is typically an attempt to recoup
      losses by salvage harvesting large volumes of timber in the affected
      but this philosophy needs to be reexamined, said Dr. Fiona
      who co-authored a paper just published in the prestigious journal

      Schmiegelow and Dr. David Lindenmayer from the Australian National
      University, found that salvage harvest operations after natural
      disturbances can threaten some organisms when large quantities of
      biological legacies are removed. "This may result in compounding,
      cumulative or magnified effects on ecosystem processes and elements of
      biota if an intense natural disturbance event is soon followed by an
      intensive human disturbance," said Schmiegelow, a professor in the
      Department of Renewable Resources.

      The research team argues that large areas need to be exempt from
      practices to maintain key ecological processes and facilitate recovery
      following the disturbance, but where these practices are done, strict
      policies need to be in place.

      Catastrophic events can aid ecosystem restoration by recreating some
      the structural complexity and landscape diversity lost through
      intense management of natural resources. For example, floods can
      areas and revitalize human-modified aquatic ecosystems while major
      wildfires generate significant volumes of dead snags and downed trees
      provide important habitat often depleted by certain forestry
      Although scientists now recognize the importance of natural
      and the biological legacies produced by them, policy makers and
      resources managers are lagging behind, say the authors. "Maintaining
      areas where the natural disturbance regime operates unimpaired by
      activities is an important component of any biological conservation
      strategy, and for ecological sustainability," said Schmiegelow.
