1 Key Features of Early Seral Habitats for Wildlife Joan Hagar USGS-FRESC Matt Lee

3 Following Natural Disturbance... Structure –Legacy trees and snags –Open (low tree density) –Large wood Composition –Herbs and Grasses –Shrubs –Deciduous hardwoods Bob Altman

4 Species associated with closed canopy forest also use early seral habitats… IF appropriate habitat elements are available

5 Species that specialize on conifers Red Tree Vole Hemlock Looper Red Crossbill

6 Many conifer forest associates rely on diversity of plants Spruce Grouse

7 Elements of Quality Early Seral Habitat

8 Residual trees and snags Matt Lee D. Vesely

9 Cavity-nesters in burned forests Fire-killed snags are important resource for foraging and nesting Many species respond negatively to salvage logging

10 Bob Altman

11 D. Vesely Early Seral Habitat for Reptiles Basking Prey

12 Dead Wood as Refugia D. Vesely

13 Plant Diversity = Food Resources Foliage Nectar Fruits Seeds

14 Plant Diversity: foundation of food webs

15 Matt Lee

16 Arthropods Insect diversity correlated with plant diversity Deciduous species support more insects Influence of deciduous litter on soil food webs?

17 Peter LaTourrette

18 Importance of Early Seral Broadleaf Communities to Avian Biodiversity

19 30 Year Trend for Swainsons Thrush from Tillamook S.F. BBS Route

20 Creating Early Seral Habitat?

24 Effects of Conifer-centric Forest Management on Early Seral Habitat Fewer residual structures Altered vegetation composition –Alters patterns of food abundance –Reduces diversity of food resources –Alters food webs Reduced temporal span

25 Consequences of reduced temporal span of early seral habitats Limit on shrub size and age Shortens duration of shrubby habitat Reduced persistence of shrubs into mid- aged forests

26 Restoration of Late Seral Forest Emphasizes large trees Size limit on harvest area on federal lands What will understory look like?

27 Keep all the pieces
