Conservation on National Forests

USFS PNW Region
Goods & Services:
• Water
• Carbon sequestration
National Forest System
193 million acres
155 national forests
20 national grasslands
422 T&E species (31% of U.S. total)
156 plants
92 fish
57 clams
32 mammals
30 birds, etc.
Current Major Stressors
• Drought
• Altered fire regimes
• Invasive plants
• Insects & disease
But what to do here, now?
• What climate are we managing for? 2030,
2060, 2090?
• Which GCM & emission models to use?
• What species & ecosystems to protect?
• What species to emphasize in
reforestation/restoration activities?
• What species combinations?
• What seed sources?
Constraints
• “206” Effect

–
Inadequate resources (funding, people)
Administrative burdens
Travel restrictions
Lack of support
• Regulatory/policy/process issues
• Land allocations
• Public opposition

Adaptation Priorities:
Resiliency & Protection
1) Expand efforts to develop native seed
supplies & production capabilities
2) Develop solutions for seed deployment
– Seed zones
– Assisted migration
3) Expand gene conservation efforts
1a) Seed Supplies: Conifer spp.
• Existing supplies are aging &
losing viability
• Wildfires & other disturbances
are depleting supplies
• Many spp. & sources are absent
or poorly represented
• Inadequate
funding
Seed Orchards
• 3773 acres, 50 species
• high value seed sources
• irreplaceable genetic
repositories
Needs:
• maintenance & protection
• consolidated maps &
databases
• additional facilities?

What to do in
the meanwhile?
• Increase accessibility
and usability of climate
data
• Delineate areas of similar
climate for use as
surrogate seed zones
What to plant for future climates?

Tree Species of Concern
Western regions:
Eastern regions:
• butternut
• oak spp. (>50)
• ash
• eastern hemlock
• 5-needle pines: white pine, sugar pine,
whitebark, bristlecone, limber, pinyon,
foxtail
• Port-orford cedar
• Western red cedar
• Subalpine fir
• Mountain & western hemlock
• Englemann spruce
• Tanoak
• Monterey pine, knobcone pine
• Cupressus spp.
• Torrey pine
• Brewer spruce
• Coast redwood
• Alder spp., cottonwood, aspen, birch
In situ Protection May be Inadequate
• Many populations are in decline
and at high risk of loss
Hemlock wooly adelgid
 Beetle epidemic
 Expanding blister rust
 Root & stem diseases
 Wildfire, drought, cc related stress
• Spp. may not be suited to future
climates
Butternut canker
Sudden oak death
Blister rust
Pitch canker
Re-thinking In situ Conservation
Active Risk Management :
• Reduce disturbance probability
• Reduce disturbance intensity
• Mitigate loss
 fuels reduction, thinning
 stimulate natural regeneration
 individual tree protection
 resistance breeding
 population augmentation or
translocation
 greater emphasis on ex situ
Ecosystems in Peril: Whitebark Pine
• Keystone spp in alpine ecosystems
• Vital food source for grizzlies, Clark’s Nutcracker
• Threatened by WPBR, mountain pine beetle, fire suppression
and climate change
• Petitioned for federal listing in 2008
PNW Whitebark Pine Conservation Strategy
Carol Aubry, Don Goheen, Robin Shoal
Priority Actions:
• Continue inventory, monitoring,
& assessment work
• Collect seed, fast!!!
• Expand efforts to develop rust
resistant planting stock
• Increase active restoration:
(planting, thinning, pruning)
• widespread cone crop
in 2009
• cone caging is ongoing
• operational & ex situ
collections in priority
areas, fall 2009

Seed Zone Benefits
• Improved adaptability
• Increased efficiency
- reduced # of management units
- Zones cross administrative
boundaries
- Creates opportunities to
pool funds
- Facilitates sharing and exchange
of seed
• Reduced costs
- larger seed needs per zone
- agronomic efficiencies
• Improved seed supplies
“Workhorse Species”
• Broad ecological amplitude
• Establish/grow/compete well on
disturbed sites
• Easily collected and propagated
• Diverse array (functional group
diversity)
“Workhorse” Species:
Grasses:
• Blue wildrye
• Bluebunch wheatgrass
• Mountain brome
• Sandberg’s bluegrass
• Great basin wildrye
• Idaho fescue
• Squirreltail
• Prairie junegrass
• Stipa spp.
• Slender hairgrass
Forbs:
• Yarrow
• Pearly everlasting
• Buckwheat
• Blue flax
• Lupinus spp.
• Penstemon spp.
• Aster spp.
3 - year priorities
• Western White Pine
– Continue existing program
– Increase outplanting opportunities
– Reexamine seed zones under climate
changes scenarios
– Increase survival and natural regeneration in
existing stands
• Pruning to increase survival
3 - year priorities
Limber, Whitebark, GB Bristlecone, RM
Bristlecone, Foxtail, Southwestern White Pines
– Initiate/continue rangewide seed collections
– Resistance screening / ID resistance mechanisms
– Define geographic patterns of adaptive traits, and define
seed zones under climate changes scenarios
– Increase survival and natural regeneration in existing
stands
• Understanding colonization dynamics
• Stimulate natural regeneration
• Individual tree protection
