    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….
