Cheryl Friesen - What are the components of high quality early seral forests? Cheryl Friesen - What are the components of high quality early seral forests? Presentation Transcript

  • What are the components of high quality early seral forests? Cheryl Friesen, Science Liaison, Willamette NF (presenter) and Brenda McComb, Professor, Univ of Mass.
  • The world view of forestry…
  • Notice the naked area in the lower left?
  • I would submit that the emperor has no clothes!
    • The “Emperor Has No Clothes Award” …presented to you and me for our lack of recognition of a biodiversity rich natural habitat type…
  • What is the best dressed early seral forest wearing these days? (to stretch the metaphor)
    • Snags
    • Large trees
    • Shrubs
    • Down logs
    • Tree Seedlings
    • Hardwoods
    • Grasses and forbs
  • Side-bar: WHAT DID I GOOGLE TO FIND PHOTOS OF COMPONENTS OF HIGH QUALITY EARLY SERAL FOREST ? OLD GROWTH FORESTS….
  • MORAL OF THE STORY…
    • Legacy

    • Managing for complexity in early successional forests is likely to be most successful if the preceding seral stage is also complex prior to a disturbance.
    • Managing for complexity through a rotation or sere helps to ensure the continuity in habitat elements over time.
  • This habitat is more popular than you might have thought….
    • Analysis of wildlife on the Willamette National Forest found
      • 14 species tied specifically to old growth
      • 0 species tied specifically to mid seral
      • 116 species generalists….use all stages
      • 71 species tied specifically to early seral
      • and edges, but….
    • All of the early seral or generalist species require one or more of the structural components listed previously…
      • For example,
        • 85% need dead wood at some life stage
  • Standard adornments that come quickly to mind…
    • Deer and elk
    • Red-tailed hawks
    • Mountain bluebirds
  • But there’s more! Early seral forest = Truly a rich community
  • Reptiles
    • Western skink
    • Western fence lizard
    • Gopher snake
    • Garter snake
    • Racer
  • Birds
    • Merlin
    • Dusky flycatcher
    • Brewer’s sparrow
    • Willow flycatcher
    • Mountain quail
    • Great Gray Owl
    • White-crowned sparrow
    • Wrentit
    • Calliope hummingbird
    • MacGillivray’s warbler
  • Mammals
    • California myotis
    • Pocket gopher
    • California ground squirrel
    • Townsend’s vole
    • Big Brown Bat
    • Badger
  • Elaboration to follow….
    • Is it more complicated than we’ve given it credit for?
    • Can it be “human made?”
    • Can we “allow it” naturally?
    • Is there a proxy?
          • Food for thought….
