Traditional Ecological Knowledge  “ A cumulative body of knowledge, practice, and belief, evolving by adaptive processes and handed down through generations by cultural transmission, about the relationship of living beings (including humans) with one another and with the environment…is both cumulative and dynamic, building on experience and adapting to changes ” (Berkes 1999:8 in Sacred Ecology).

Cultural Environmental Management Practices  “ Practices employed by Indigenous peoples often mimicking natural disturbance processes in the management and utilization of natural resources” – Lake (2003).  Also called: Indigenous land use practices, Native American land management, traditional resource management, etc.

Cultural Environmental Management Practices  Mimic natural physical and biological disturbance processes Fire (seasonality and location may differ) Animals (extent and duration may differ)

Cultural Environmental Management Practices  Buffer against extreme ranges of natural variability  Fosters biodiversity and productivity  Can be applied to research, management and restoration efforts today

Humans? Lertzman, Spies, and Swanson 1997

Indigenous/Cultural Fire Regimes  Alternate seasons of burning for different kinds of settings.  Frequencies with which fire are set and reset over varying periods of time.  Corresponding intensities with which fuels can be burned

Indigenous/Cultural Fire Regimes  Specific selection of sites fired and those that are not.  A range of natural and artificial controls that humans employ in limiting the spread of fire: time of day, winds, fuels, slope, relative humidity, and natural/human fire breaks – Lewis 1982

Fisheries  TEK and Western Science

Fisheries: Salmon  Traditional Fishing Practices  Scientific Monitoring  Collaborative Learning

TEK and Resource Management  Hydrology, Water Quantity and Quality Landscape level use of fire influenced vegetation communities affecting interception, infiltration, evapo-transpiration, and soil moisture retention levels in watersheds. Prescribed fires influenced water yield affecting the timing and amount of surface runoff and spring fed flows to the channel networks. Photo: Biswell 1989

TEK and Resource Management  Plant Community Ecology-Physical and Biological Interactions Historical or Reference Ecosystem Processes and Function Climatic or Natural Variability Management Needs to Restore or Maintain Threatened or Endangered Plant Species or Communities Plant, Soil, Wildlife/Insect Interactions Restoration or Conservation of Species Invasive species

What is missing and how do we return it back to being a functional part of the bigger systems again? Are there remnants of a once healthier more diverse and productive ecosystem?

What is our reference?  What do we compare our present condition to?  Is how it was… what we want now? Do we value what it was like and the services it provided? Are there things that we want now that were not desired in the past?

Questions? How might TEK and/or an Indigenous perspectives of land management or restoration practices be of value in your program or projects? What do you think are the advantages of incorporating TEK in to research or management?
