    Contrasting Restoration Efforts

    on the

    Fraser and Columbia Rivers The Fraser and Columbia are the two largest watersheds

    in the PNW, together draining 343,000 sq. miles. TheFraser is noted for its sockeye runs; the Columbia was

    noted for its chinook runs (historically producing morechinook, coho, and steelhead than any other river in theworld)

    Restoration efforts on the Fraser emphasized scientificresearch on migration routes, etc. while refining counting

    methods, but science was given low priority on theColumbia, where dams were built and money was putinto hatcheriesan example of American techno-optimism(Lichatowich, 1999)

    Results of Salmonid Restoration Efforts

    on theFraser and Columbia Rivers

    Fraser River sockeye runs increased (from 3.3 million in1949 to 22 million in 1990)

    Columbia River chinook crashed from historical runs of 8to 10 million to 450,000 in 1993 Hatchery production on the Columbia was ineffective in

    making up for changing ocean conditions (beginning in1976); hatchery fish are more vulnerable to unproductive

    ocean conditions Performance of salmon in the ocean is not independent

    of human manipulation of the fresh water phase of theirlives(Lichatowich, 1999)

    Changing Ocean Conditions

    Changes in ocean currents can reduce abundance of phytoplanktonthat support fish species that salmon prey on

    E.g., if springtime ocean currents change, the advantages of mixingof cold deeper waters with shallow warmer waters that provide coldwater nutrients to phytoplankton will be lost and salmon health will

    deteriorate

    Global warming/El Nio events can shift fish runs to the north, asmay have happened with the unusually high numbers of sockeye in2010 returning to the Fraser River (Canadian northern route) and

    bypassing US southern route

    The Missing Sockeye of 1994

    14 million sockeye returned to the Fraser River in 1988 and 22million in in 1990, but the 1994 run was nearly obliterated: 2 million

    sockeye (of 3.3 million estimated salmon) were lost and fisheries

    were closed down. Fishing quotas had been set at 80% and nearly

    caused zero reproduction

    Tribal poachers and logging were blamed. A complete ban ontribal fishing was proposed (although tribes accounted for < 5% of

    salmon taken annually). Sockeye runs in the late 90s and 2000s

    were well below the 1980s until 2010.

    Lesson: While Canadian fisheries practices were better managedmore holistic with an ecosystem management approach and with

    science guiding the processchanges in ocean conditions were not

    well understood and still are not

    Historical Eco-cultural Richness of the PNW

    Recent research suggests that the social andcultural richness of Pacific Northwest tribes wasthe result in part of sophisticated political and

    legal systems linked to sophisticated resourcemanagement and harvest technologies

    A stable food supply was ensured by thedeliberate spread of salmon and enhancedcomplexity of habitats by First Nations peoples-increasing salmon abundance, diversity, anddistribution(Nigel Haggan, UBC fisheries Centre, 2004)

    Native People Cared for Salmonid Freshwater Habitat

    Given the uncertainty of oceanic conditions, Nativepeople had to work hard at maintaining quality salmonstream habitat

    Spawning beds were cleaned and log jams removed followinglarge storms

    Sandspits blocking late summer/fall chinook runs were opened Trees were felled to divert stream water into side channels

    creating backeddies for overwintering coho or to flush sedimentfrom spawning beds

    Salmon spawn were transplanted in damp moss to streams withno or few salmon

    Salmon were flumed or carried around landslides or iceblockages (this happened most recently in 1914 following thehuge slide on the Fraser River at Hells Gate canyonsavingsockeye runs)

    Other conservation measures included:

    Complex stone fishtraps for a wide range of marinespecies (including herring, eulachon, and perch)which were species and size specific (Herring wasand still is farmed on submerged hemlock boughs)(Nigel Haggan, 2004)

    Use of weirs at river mouths to count and thencontrol harvestable fish before allowing them upriverto their natal spawning streams and other tribes

    Local Control Over Local Resources

    These and other conservation measures were sustainablymaintained by a land tenure system which divided fisheries andother marine resources (e.g. farmed clam beds) into units of localresponsibility and harvesting rights by individuals, families, andclans nested within a larger, collective tribal authority structurethrough which experienced knowledge specialists had the lastword on harvest regulation and rights during times of regional orseasonal shortages of particular runs

    Fishing at the mouths of rivers and streams allowed accurate fishcounts, with quotas for use based on the relative abundance of

    different fish runs

    Trading between families of different salmon species ensured adiverse food supply and good nutrition (Nigel Haggan, 2004)

    Adaptation to Climate Change

    Adaptation to climate change will depend in large part in

    the futureas it did for millennia with aboriginal fisheries

    on a wide range of practical aquatic and terrestrialrestoration and conservation measures which in sum

    enhance the genetic diversity of salmon by maintaining

    high enough population numbers of all 5 salmonid

    species to ensure genetic adaptability to warming

    oceans and rivers.

    [Those practical activities will be discussed in detail in the 2nd half of this

    presentation]

    Adapting the Indigenous ecosystem-based model to modern

    conditions in complementarity with Western science

    Adopt a holistic fisheries ecosystem managementstrategyinstead of single species population modeling

    addressing restoration in both upland terrestrial(watershed) and riverine and estuarine-marine habitat

    Work toward a site-specific local (community-based)regulatory structurelocal responsibility for localresourcesnested within larger tribal, regional, and state

    Use fishing gear which is species and size specific Favor natural regeneration of wild salmon stocks over hatchery fish where possible Find a balanced number of transferable license quotas and buy-backs of licenses by

    governments (e.g. Canada) to encourage local access and control of local resources and

    achieve distributive social justice while reducing fishing pressure on salmon. No open

    access, but some constraints on transferable quotas needed to reduce social disruption.

    (Coward et al, 2000; Berrill, 1997)

    Utilize both Western science and traditional ecological knowledge (TEK). Local knowledgeprovides important information on stock structure, spawning grounds, juvenile habitat,

    and seasonal and directional fish movements.

    Scrap maximum sustainable yield model in favor of whole ecosystem\multispeciesmanagement (Iceland and Norway are already doing so)feasible in relatively simplecold ocean systems

    No to No Net Loss salmon recoveryuse historically reconstructed baseline modelsinstead of just going with current population numbers as a baseline, e.g. target salmon

    numbers lost to habitat destruction and dams instead of comparing cost of hatcheries vs.

    income from fishing as a metric of sustainability

    Ecosystem Management at the Watershed

    Level and Climate Change Adaptation

    Broad Goals

    1. Maintain or restore key aquatic and riparian habitatstructure, composition, and processes (e.g. hydrologicfunction) affecting all organismsnot just fish (e.g.

    invertebrate species richness: 196 terrestrial vertebratespecies, besides fish, utilize streamside macro-invertebrates)

    2. Maintain or restore key upland forest structure,composition, and function with a broad range of light-shade conditions where possible by approachinghistorical tree stocking rates, landscape configuration,and composition to the extent possible given changedlandscape scale environmental conditions

    Ecocultural Restoration

    The process of recovering as much as is recoverable of the key

    historic precontact ecosystem structure, composition, processes,

    and function, along with traditional, time-tested, ecologically

    appropriate and sustainable Indigenous cultural practices that

    helped shape ecosystems, while simultaneously building-in

    resilience to future rapid climate disruptions and other

    environmental changes in order to maintain ecological integrity in

    a way that ensures the survival of both Indigenous ecosystems

    and cultures

    Mimicking Native American Fire Regimes in their

    Intensity, Frequency, Seasonality, Selectivity, and

    Landscape Scale Pattern

    The 100s of plant species utilized by First Nations

    required a watershed level fire regime based on

    periodic, low-intensity burns done rotationally at afrequency of from one to 10 or 15 years depending

    on the resource targeted and its phenologyapplied

    to a wide variety of plant communities rich in cultural

    resources, including forest herbaceous understories,

    montane meadows, prairie-savanna, wetlands,shrub-steppe, and riparian zones

    Erosion Mitigation Measures

    Minimize erosion by substituting mechanical thinning forfire in erodible soils (e.g. granitic soils) near streams

    Dont thin or burn on steep (over 60%) slopes nearstreamsbalance those kinds of closed areas withadjoining opens and gaps on less steep and erodibleslopes for overall watershed structural heterogeneity

    Phase out roads and recontour slopes\restore naturaldrainage patterns by using outsloped roads instead of

    inboard ditches and culverts to restore historic hydrology

    Aim High

    Avoid shifting baselines by referring climate

    adaptation and mitigation goals to historical

    conditions (Hardison and Williams, Tulalip Tribe, 2005; Haggan, 2004)

    as an initial guide for restorationthat will be

    modified by todays changed conditions but will alsoset a restoration trajectory that recovers the

    historical range of variability of forest landscape

    heterogeneity for sufficient microsite variability to

    ensure genetic variability (a diverse gene pool) for

    adaptation of populations and subspecies to rapidclimate destabilization and change

    Global Warming Induced Changed Weather and Oceanic

    Conditions in the Pacific Northwest

    Current Ecohydrologic Conditions

    Winter season reduced by roughly 2 months Longer warm fall rains and shorter spring snowmelt More precipitation falls as rain than snow, reducing snowpack Snow melts more rapidly and earlier in spring, resulting in higher peak

    flows

    Increased flows increase erosion and floods that deliver higher sedimentloads, nutrient loads, and contaminants in downstream receiving waters,

    causing scouring and sedimentation; reduces infiltration and capacity of

    wetlands and riparian vegetation to filter nutrients and toxins in runoff(Hardison and Williams, 2004)

    Earlier snow melts are causing water to be available up to ~ 2 months before thenormal times of salmon arrival

    Ocean acidification is reducing available calcium for shellfish and juvenile bonedevelopment of some fish species

    Temperature Alterations

    Loss of forest cover from clearcut logging has resulted inless stream shading and faster spring runoff; removal of

    large logs has resulted in poor stream structurewithfew or no deep pools for summer cooling

    Warm water induces whirly disease in salmon andincreases their susceptibility to other aquatic diseases(Hardison and Williams, 2004)

    Loss of groupings of tall old-growth trees has reducedhumidity in forests with increased drying of forestunderstories, overstocked smaller trees and ladder fuels

    resulting in increased fire hazard

    Species Range Shifts

    As oceans warm, salmon have no place to go but north,e.g. sockeye salmon may move to the Bering Sea.(Haggan, 2004)

    The extremely rapid rate of climate change could trapterrestrial species which may have a wide ecologicalamplitude but have genetically fixed times forreproduction and feeding resulting in population declinesand loss of tribal resources. (Hardison and Williams, 2004)

    Evolutionary opportunities will increase for invasivegeneralist species and decrease for more conservativespecies

    Balancing Carbon Sequestration with Restoration of

    Biodiversity and Fire Hazard Reduction

    Use variable density thinning model (Lindenmayer and Franklin, 2002)to create structural and compositional heterogeneity

    Thin to release permanent old-growth softwoods and hardwoodsforreducing fire hazard and for future understory moisture retention andcarbon sequestration both in trees and in soil organic matter/legacy

    charcoal, enhanced by forest openings which support rich perennial

    herbaceous and fern understories

    Structure longterm timber harvest rotations (120 years or longer) andfuture permanent old-growth trees in groupings which provide a widerange of light-shade conditions appropriate to the forest typefor

    biodiversity, species composition, and gene pool restoration (facilitated

    by enough spacing between tree groupings to allow good gene flow)

    Restoring Forest Hydrologic Function to Benefit

    Salmonid Aquatic Habitat

    Remove sufficient number of smaller treesespecially invasive shadetolerant conifers in interior coastal mountainsto reduce

    evapotranspiration and increase groundwater quantity

    Restore beavers for groundwater recharge and increased fish diversity,abundance, health and juvenile survival

    Increase soil infiltration capacity by creating openings and gapsandmaintaining montane meadowswhich support long-lived herbaceous

    perennials such as native bunchgrasses with extensive root systems

    which can loosen compacted soils in the appropriate plant

    communities. Native grasslands are a good underground carbon sink.
