Results of Habitat Study
• Forest stands at unoccupied sites were taller had less structural diversity and were less dense than stands at occupied sites.
• Occupied sites had more earlier successional species than unoccupied sites.
• Occupied sites were larger than unoccupied sites (198 vs. 181 ha).
• Occupied sites were closer to one another than unoccupied sites were to occupied sites (x = 3.2 km versus 11.8 km). Photo: Glenn Johnson

Goal:
Translocate spruce grouse into areas of their NY range to help lead to the population’s recovery
Hypotheses
Translocated and resident spruce grouse will have similar annual survivorship rates, home range sizes, and productivity
Sample sizes needed:
• 51 spruce grouse home ranges
• 41 spruce grouse mortality rates
• 11 nests
(with 95% confidence)

1. Document historic trend in
otter population within
recovery zone
2. Assess current status of river
otter in areas closed to
harvest
3. Provide robust, efficient and
non-harvest based plan for
monitoring changes in otter
populations
• Site occupancy design
• Winter bridge-based
surveys
• Alternative methods?
General approach

Hunter fell from the stand when a ratchet strap
securing the stand to the tree broke.
Victim had just entered his stand when the wooden
platform collapsed. Victim was attempting to attach his safety harness at the time.
While sitting in tree stand, one of the nylon straps for the suspended seats failed, causing the individual to list
to one side and fall approximately twenty feet
to the ground.
Victim was in his stand when the entire stand broke away from the tree and collapsed.
Victim was climbing the tree when the top part of the
stand broke at approx 16ft. The stand was old and
rusted. A metal loop which held the stand to the tree
broke due to rust.

Current Forest Conditions
• Land use favors younger forests and reduced species diversity
• Stressors include: land use change, parcelization, fire, invasive alien species, diseases and pests, overbrowsing and extreme weather events
• 90% of the forest is suitable for wood production
• annual harvests are less than growth
![Page 84: Spruce Grouse Update · Home ranges of translocated grouse were of similar size to those of resident grouse: Translocated CI n Resident CI n P ♀ 27.10 22.32-32.90 33 57.68 44.95-74.01](https://reader036.vdocuments.us/reader036/viewer/2022062508/605ee5ab0de97b2ced6795ac/html5/thumbnails/84.jpg)
Observed Climate Change
• Precipitation patterns have changed across the region
• Greater annual precipitation, increase in extreme precipitation events, decrease in snowfall amounts
• Substantial sea-level rise (12 inches or more)
• Reduction in lake ice, increased growing season length, plant and animal shifts
![Page 85: Spruce Grouse Update · Home ranges of translocated grouse were of similar size to those of resident grouse: Translocated CI n Resident CI n P ♀ 27.10 22.32-32.90 33 57.68 44.95-74.01](https://reader036.vdocuments.us/reader036/viewer/2022062508/605ee5ab0de97b2ced6795ac/html5/thumbnails/85.jpg)
“Projected” changes in climate and physical processes.
• Continued temperature increases in winter.
• Increased winter/spring precipitation. Summer/Fall precipitation events are more variable. More intense precipitation events.
• Shorter and milder winters, continued declines in snowfall but more winter rains.
• Shorter periods where soils are frozen
![Page 86: Spruce Grouse Update · Home ranges of translocated grouse were of similar size to those of resident grouse: Translocated CI n Resident CI n P ♀ 27.10 22.32-32.90 33 57.68 44.95-74.01](https://reader036.vdocuments.us/reader036/viewer/2022062508/605ee5ab0de97b2ced6795ac/html5/thumbnails/86.jpg)
“Future” Climate Change Impacts on Forests
• Reductions in Boreal species such as spruce and fir
• Increases in species with ranges to the south such as red maple, red oak and cherry
• Hotter dryer summers may cause common species to decline especially in the south
• Forest productivity will be influenced by factors such as Carbon Dioxide and moisture
![Page 87: Spruce Grouse Update · Home ranges of translocated grouse were of similar size to those of resident grouse: Translocated CI n Resident CI n P ♀ 27.10 22.32-32.90 33 57.68 44.95-74.01](https://reader036.vdocuments.us/reader036/viewer/2022062508/605ee5ab0de97b2ced6795ac/html5/thumbnails/87.jpg)
“Potential” Impacts on Drivers and Stressors
• Temperatures will increase• Growing seasons will lengthen• Winter processes will change• Sea levels continue to rise• Amount and timing of precipitation will change• Intense Precipitation events will be more frequent• Soil moisture patterns will change• Increased risk of drought during the growing season• Insect pests will increase in occurrence and be more
damaging• Invasives will increase in extent or abundance
![Page 88: Spruce Grouse Update · Home ranges of translocated grouse were of similar size to those of resident grouse: Translocated CI n Resident CI n P ♀ 27.10 22.32-32.90 33 57.68 44.95-74.01](https://reader036.vdocuments.us/reader036/viewer/2022062508/605ee5ab0de97b2ced6795ac/html5/thumbnails/88.jpg)
“Potential” Impacts on Forests
• Boreal tree species will face increasing stress
• Habitat will favor southern species
• Forest composition will change across the region
• These changes will take decades or longer to occur absent major disturbance
• Tree regeneration and recruitment conditions will change
• Forest productivity will increase over the next several decades
![Page 89: Spruce Grouse Update · Home ranges of translocated grouse were of similar size to those of resident grouse: Translocated CI n Resident CI n P ♀ 27.10 22.32-32.90 33 57.68 44.95-74.01](https://reader036.vdocuments.us/reader036/viewer/2022062508/605ee5ab0de97b2ced6795ac/html5/thumbnails/89.jpg)
Adaptive Capacity Factors
• Low-diversity systems are at greater risk
• Fragmented landscapes will have reduced ability to migrate in response to climate change
• Species or systems with narrow habitat requirements will have less opportunity to migrate
• Ecosystems that have greater tolerance to disturbance have less risk of declining on the landscape
![Page 90: Spruce Grouse Update · Home ranges of translocated grouse were of similar size to those of resident grouse: Translocated CI n Resident CI n P ♀ 27.10 22.32-32.90 33 57.68 44.95-74.01](https://reader036.vdocuments.us/reader036/viewer/2022062508/605ee5ab0de97b2ced6795ac/html5/thumbnails/90.jpg)
Management Implications
• Plants, animals and people that depend on forests may face additional challenges as the climate shifts
• Greater financial investments may be required to manage forests and infrastructure and to prepare for severe weather events
• Activities such as wildfire suppression or recreational activities (snowmobiling, skiing etc) may need to be altered as temperature and precipitation patterns change
• Climate change may present opportunities for forest products industry, recreation and other sectors if changing conditions are anticipated

Reducing Atmospheric GHGsWood Substitution
1. The use of wood products avoids the omissions from substituted products and forest carbon remains in storage
2. Wood from sustainably managed forests can be replenished continually while providing services like clean water and air
3. Life cycles reveal that forest products store more carbon, emit less GHGs and use less fossil fuel than steel, concrete and other products.
4. Wood Product substitution doesn’t permanently eliminate carbon from the atmosphere

Reducing Atmospheric GHGsBiomass Substitution
• Harvest residue for power generation
• Biomass can be substituted for coal, natural gas, gasoline and fuel oil.
• Direct burning, hydrolysis and fermentation, pryolysis, gasification and other processes are used to turn wood into energy or fuel
• We will need to build 1,200 power plants in the next 25years to keep up with energy demands
• Every BTU of gasoline that is replaced with cellulosic ethanol reduces GHGs by 91% according to life cycle analysis.

Reducing Atmospheric GHGsWildfire Behavior Modification
• In Lake Tahoe, 2007, a 3,100 acre fire released 141,000 tons of CO2 into the atmosphere
• Future wildfire emissions are likely to exceed current levels.
– Pretreatment for fuel reduction
– Schedule low-severity prescribed burns
– Harvest small wood for energy

Reducing Atmospheric GHGsAvoided Land-use Change
• Forests store more carbon than agricultural lands or developed lands
• Between 1850 and 1998-forest land conversions released more carbon to the atmosphere than any other human activity besides energy production
• Forest land returns are less than those for development
• Corn ethanol production encourages forest to agriculture LU change

Reducing Atmospheric GHGsSequestration in Forests
• Hardwoods and evergreens absorb about the same amount of carbon
• Mixed species, mixed –age stands have higher capacities for carbon uptake and storage
• Management to ensure full stocking, health and less soil disturbance means greater uptake
![Page 97: Spruce Grouse Update · Home ranges of translocated grouse were of similar size to those of resident grouse: Translocated CI n Resident CI n P ♀ 27.10 22.32-32.90 33 57.68 44.95-74.01](https://reader036.vdocuments.us/reader036/viewer/2022062508/605ee5ab0de97b2ced6795ac/html5/thumbnails/97.jpg)
Reducing Atmospheric GHGsStorage in Wood Products
• Harvesting reduces forest carbon storage by removing organic matter and disturbing soil
• Carbon in wood removed is stored in forest products
• Products can store carbon for long periods and reduce emissions through product substitution

Some Problems Not in the Studies
• Bad news for forests: Beeches booming as climate changes - A scientific paper shows environmental changes are squeezing out important tree species.
• New York Petitions U.S. EPA to Protect State's Air Quality - Petition Seeks Emissions Reductions from Power Plants and Industrial Sources in Nine States that Jeopardize New York's Ability to Meet Ozone Standards

Some Conclusions
• Society’s current reluctance to embrace forest management as a partial way of addressing climate change is surprising
• The health and welfare of 7.5 billion humans depends on the health and welfare of forests
• Never say never or always – Forest Pre(re)serve.• Anti-harvest groups and urban populations• Wind Turbines and Solar panels vs. trees• Balloon Theory• Climate is Complex!! Retain Flexibility!!
