What are the components of high quality early seral forests? Cheryl Friesen, Science Liaison, Willamette NF (presenter) and and Brenda McComb, Professor, Univ of Mass.
The Emperor Has No Clothes Award …presented to you and me for our lack of recognition of a biodiversity rich natural habitat type… 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 Snags Large trees Large trees Shrubs Shrubs Down logs Down logs Tree Seedlings Tree Seedlings Hardwoods Hardwoods Grasses and forbs 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… LegacyLegacyLegacy 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 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 85% need dead wood at some life stage
Standard adornments that come quickly to mind… Deer and elk Deer and elk Red-tailed hawks Red-tailed hawks Mountain bluebirds Mountain bluebirds
But theres more! Early seral forest = Truly a rich community
