Crown lands and the spirit of the treaties

this piece of Crown land has been sold and is slated for development
Christmas Bird Count, late December.

We stop the car beside a piece of Crown land southeast of Regina Beach, a 160 acre parcel that the Saskatchewan government has recently sold. It is pasture land so I step out of the car and over the fence to have a look and see if it is native grass. The withered stalks and seed heads poking through the thin cover of snow look native to me but in winter it can be tough to identify grassland plants so I snip a few samples and carry them home to figure them out. Later, and with the help of a botanist friend, I name them, all natives: Slender wheatgrass, June Grass, Gumweed, Long-fruited anenome, and prairie coneflower.

The pasture is not in perfect condition. There are some non-natives too, but even the best grasslands have a few weeds these days. As we drive on we watch a sharp-tailed grouse perched on the fence. A herd of 14 mule deer move from one aspen bluff to the next through thickets of snowberry and wild rose.

A friend who lives in the area told me a few weeks ago that the quarter section—once leased Crown land and now in private hands—is going to be developed, subdivided, and sold as acreage or resort property. There is another quarter section of Crown land south of it—mostly native grass and bush as well—that was once protected by the Wildlife Habitat Protection Act (WHPA). It has not been sold yet, but may well go private soon because it appears to no longer be protected by WHPA designation.

When the numbered treaties were signed in this part of the world, back in the 1870s, there were roughly sixty million acres of native grassland south of the forest in what we now call Saskatchewan. Those who signed the treaties, agreeing to share the wealth of the prairie with newcomers, were assured that they and their descendents would always be able to hunt and gather medicines and move through the prairie. No one mentioned that the land would soon be plowed, turned upside down and cut up into parcels for the exclusive use of settlers.
Today we estimate we have somewhere near ten million acres[1] of native grassland left in mostly small pieces in various states of health. That means we are down to less than 20% of our natural cover south of the forest. A report soon to be released by the World Wildlife Fund shows that Saskatchewan continues to lose native grasslands and wetlands at an alarming rate—in some areas as much as 13% a year, the worst of any state or province on the northern Great Plains.

A little less than half of our remaining natural prairie land is owned privately. Approximately 5.9 million acres are leased to private ranchers. Land owners and leaseholders of “Crown agricultural lands” have the legal right to deny access to anyone, including indigenous people.

Last month, in response to charges that his government is bullying indigenous hunters (news story here; Doug Cuthand’s excellent column on the topic here), our premier made this point in the Globe and Mail and on CBC, saying "Whether you have a treaty card or not, you still need the permission of the landowner to hunt on private property."  

What Premier Wall did not say was that indigenous people south of the forest have very few places off-reserve where they can go to hunt and engage in cultural practices.

In fact, his government is actively making sure that there will be less Crown land when they are done with Saskatchewan. The Sask Party has a stated policy of privatizing Crown lands. Lyle Stewart, the Minister of Agriculture has repeatedly said that the government does not need to own land, which for his ministry is Crown lands south of the forest.

From November 2008 to December 2014, the Sask Party sold a half million acres of land that used to belong to all of us, indigenous and non-indigenous alike.

In 2012, when Stephen Harper cut the federal PFRA pasture system and transferred 1.7 million acres back to Saskatchewan, the Sask Party said they would either sell or lease the Crown land to the cattle producers who graze it. That process shifting these endangered landscapes to private leaseholding management is about half way through the transition, but in effect it removes many of the last and best places for indigenous people to access Crown land.

Then, in spring of 2014 the Saskatchewan government proudly announced that they were ranking the WHPA lands for ecological value and may eventually be selling as much as 1.8 million acres of former WHPA lands.

After that, last fall, Lyle Stewart announced that Saskatchewan Agriculture would begin selling another 600,000 acres of Crown land—this time at a 15% discount. Leaseholders who do not purchase will find their rental rates climb by 15 and then 30% within two years. 

With Crown land now up for discount sale and the community pastures being leased to private grazing businesses, there are fewer and fewer places where indigenous people are free to hunt or gather medicines. As for asking permission, many farmers and ranchers restrict hunting on the land they manage or own and some may be particularly unwilling to grant permission to Metis or First Nations hunters.

There may be enough latitude under the treaties and in our court system’s interpretation of their language for provincial governments to get away with this kind of erosion of indigenous rights to access the land, but Canada has signed international agreements that refer specifically to the rights of indigenous people in this regard.

For example, we signed the United Nations Declaration on the Rights of Indigenous Peoples, which states clearly in Article 26:

1. Indigenous peoples have the right to the lands, territories and resources which they have traditionally owned, occupied or otherwise used or acquired.
2. Indigenous peoples have the right to own, use, develop and control the lands, territories and resources that they possess by reason of traditional ownership or other traditional occupation or use, as well as those which they have otherwise acquired. 3. States shall give legal recognition and protection to these lands, territories and resources. Such recognition shall be conducted with due respect to the customs, traditions and land tenure systems of the indigenous peoples concerned.

In addition, Target 12 in Canada’s 2020 Biodiversity Goals and Targets state that “customary use by Aboriginal peoples of biological resources is maintained, compatible with their conservation and sustainable use.”

Are these documents and the treaties themselves merely words or do they actually mean we have a responsibility to ensure that indigenous people have access to more than the small scraps of land they own on reserves and gain through treaty land entitlement?  

The spirit under which the treaties were signed would suggest otherwise; that we share, as indigenous and settler peoples, a sacred obligation to conserve public lands so that our descendents will have wild prairie places where we can walk and know the old ways of grass and meadowlark song.

The Saskatchewan Party is not just selling land; it is violating the very spirit of the treaties that make us who we are and form the foundation of our social contract as prairie people.

North Dakota study shows wind turbines in native grassland to be bad for birds

Jill Shaffer of the U.S. Geological Survey authored the longest-ever study of the effect of wind turbines on prairie grasslands birds

While we wait with fingers crossed for Saskatchewan Environment Minister Herb Cox to release his decision on the Chaplin Wind Energy project (see other Grass Notes stories here), the case against installing wind energy projects on native grassland is gaining ground.

From Saskatchewan Ministry of Environment's web page on the Chaplin Project

A study released last summer by the United States Geological Survey makes it clear that installing wind turbines in native grassland is bad for the birds--not because birds may fly into the turning blades, but because by avoiding the disturbed areas--roads, gravel pads, the massive turbines--grassland birds are displaced and lose their critical breeding habitat.

Here is a report in the Bismarck Tribune, which describes the study as the longest of its kind. Beginning in 2003, the research compares grassland bird data on three sites of native grassland before and after the installation of wind turbines.

Looking at nine species of birds the researchers found that "seven of [them], including the meadowlark and the bobolink, were displaced from good breeding habitat for the study’s duration."

“New wind energy in prime wildlife habitat can influence the distribution of grassland birds for years after construction, including species whose populations are in serious decline,” the report concludes.

this image from the Bismarck Tribune shows one of the three study areas

Thanks to Candace Savage, author of Geography of Blood and Prairie: A Natural History, for alerting me to this report. 

Kevin Van Tighem, well known Alberta conservationist and author, posted this comment online in reference to the study:

"In southern Alberta wind projects have been located too often in large tracts of fescue grassland. The result is to fragment previously continuous habitat, eliminate aerial singers like Sprague's pipit and horned lark, and displace species like long-billed curlew and upland sandpiper that need large tracts of intact prairie. Wind can be green energy, but not when projects are put on the last good tracts of healthy prairie."

Saskatchewan can learn from the mistakes made in North Dakota and Alberta (and on our own native grasslands in the Missouri Coteau) by making sure that from now on, SaskPower and the provincial government will not support or approve wind energy projects on native grassland.

Cattle and the Fate of the Earth, Part II

In last week's post on how livestock grazing will destroy or save the earth, I took a look at the widely ranging field of opinion on climate change and domestic grazing--from the selective truths of Cowspiracy to Tim Flannery to George Monbiot, Hunter Lovins, and Alan Savory.

I ended that post with a promise to provide a bit more insight on Savory's system, which we will get to in short order.

But I want to apologize off the top to anyone who is looking for an unqualified endorsement of Holistic Management (HM). You won't find it here. But neither will you find an out of hand dismissal of it as a viable method of managing grassland. From what I have read on the topic, any management system--continuous, all-season grazing, short-duration intensive grazing, or other forms of rest-rotation--can, in the right hands and with the right stocking rates for the site, produce good results for both beef production and ecological conservation values.

As for the larger claims made by Savory and HM enthusiasts, I am going to lean a little to the skeptic's side of the fence. I am neither a grassland biologist nor a range ecologist nor a rancher. Though I do share some native prairie that we let the neighbour's cattle graze from time to time, I cannot claim any personal experience or knowledge of grazing systems.

I took this photo in the ditch just outside the fence where the cattle in the top photo were grazing--there were lots of lady slippers outside the fence but none inside. Grazing is an important element of grassland management, but there are species that do not do well under intense grazing pressure.

So why am I skeptical of Savory's claims? First, because it just sounds too good to be true and that always makes me suspicious. I can readily believe that in the right landscape with the right soil and climate, a skillful and hard-working grass manager may well increase her production by using HM methods. But I have trouble believing that any system--especially one that has never been proven by independent studies to work on a wide range of grassland eco-types--will sequester as much carbon, and improve water infiltration as Savory claims it will in his Ted talk.

Second, I worry because I do not hear many HM enthusiasts distinguishing between native and non-native grasslands--a vital distinction from a biodiversity conservation perspective. And I worry about people using HM on native grasslands, especially in areas where the land is not terribly productive or resilient.

HM and other methods of "mob grazing" or "short duration grazing," may well be effective for restoring cropland to perennial grasses--if you have the right watering infrastructure and enough labour and skill to make it work the way Neil Dennis has in Saskatchewan. But I have yet to hear of any reports showing that it improves the range condition or biodiversity of native prairie. Until we see at least one independent, peer-reviewed study showing increased biodiversity on native range, increased carbon retention, and improved range condition, I am not sure why we should get enthusiastic about the Savory method and its offspring.

Finally, I am skeptical because people I respect are skeptical. Chris Helzer, whose Prairie Ecologist blog is always even-handed and fair, had this to say about HM and Savory.

Closer to home, I asked Sue Michalsky, Eastend rancher with an MSc in range management, and a director of Ranchers Stewardship Alliance Inc. (RSAI), what she thought of Holistic Management. Here is her response:

"There are several peer-reviewed studies, including a Canadian study with Darcy Henderson as one of the authors, that demonstrate no benefits to biodiversity, carbon storage or even grass productivity associated with high intensity, short duration grazing. To my knowledge (and I watch for these), there are zero peer-reviewed studies that demonstrate a benefit to any of these factors from the use of high intensity, short duration grazing. Despite this lack of evidence, there is an ever-increasing number of people including ranchers, agrologists and environmentalists who are believers. 
What is strange is that the holistic followers view it as a panacea. That is unusual among livestock producers and agrologists. Some of my peers think that holistic grazing may be having a positive effect in severely overgrazed, tame grasslands further south where winter dormancy is not such a huge issue. But not for the reasons that Savory and HMI advertise. Simply because a very short grazing period gives grass a long period of rest that it never had before and tame grasses have been bred to grow aggressively given the opportunity.
The rational viewpoint is that grazing can be good or bad for native grasslands, as can fire. Most of the RSAI ranchers run moderate stocking rates and may rotate pastures, but usually in a low intensity situation. In wet years, they utilize less of the production than they could get away with which likely means that some carbon is sequestered in those years. In successive dry years they may utilize more grass than what is produced, also using stockpiled grass from previous years. However, it is likely that carbon is NOT sequestered in these years and may even be released as root systems die back. There is some research supporting the variability of carbon sequestration on native grasslands and I think it is by Dr. Ed Bork from U of A. 
Historically speaking, it is obvious that grazing and carbon sequestration are not mutually exclusive or grasslands in the northern great plains would not have been able to sequester such huge carbon stores in only a few thousand years. However, the bison did not graze every acre every year. I believe every 8 to 32 years was the estimate for the northern mixed grassland. In addition, it is fallacy that the bison mob grazed. There is a Nature Conservancy (TNC) study (unpublished) that looks at explorer records and aboriginal knowledge to get a handle on this. In most cases, the bison roamed locally in small family units of 20 to 50 head. They did not migrate, but they did move in large numbers away from drought and harsh winters. And possibly away from disturbances such as lots of homesteaders. Under historic conditions, high intensity, short duration grazing rarely occurred. And under those conditions, grasslands stressed by drought or winterkill of grasses did not get grazed, thereby reducing the chances that soil-stored carbon would be released.
I am not saying there are no positive effects from grazing. There are. Grazing stimulates grasses to increase primary production in the same way that exercise builds human muscle and makes us a point. In both cases there is a point beyond which the stress produces negative results. There are many studies that demonstrate increased production under grazing - an S curve model - and even some long term studies which demonstrate that production and therefore economics are better under moderate grazing than either heavy or light grazing / non-use. Moderate grazing stimulates the presence of forbs in a grassland when the climax condition is a few species of old growth grass. Many grassland wildlife species including insects respond positively to moderately grazed habitat.
To make sense of when grazing is good or bad, one need only go back to the range management basics: timing, intensity and duration. Timing in the northern great plains where winter dormancy is an overriding factor means 'at what point during the growing season'. The benefits of deferred grazing are well established. The rule of thumb is that for every day you defer grazing in the spring, you gain 2 - 3 days of grazing in fall or winter. Duration (the length of time) and intensity (the number of animal units per area) are interdependent. This is where Savory is right. He teaches that what is most important is the rest interval. In the northern mixed-grass, there are two relevant measurements. Jim Romo has some research that shows native grasses in SK need more than 400 days of rest to fully recover their root systems from a grazing event. SK Ag keeps referencing some research that I have been meaning to track down that says 'between 50 and 70% of leaf material must be left behind to continue plant growth on native grasslands'. 
In the end, Alan Savory may not be wrong in what he preaches, but preaching is different from practice. The problem is that it is a delicate balancing act to ensure that native rangelands have sufficient rest and recovery before another grazing event and most livestock producers do not have the flexibility or the intricate knowledge required to ensure only ever positive results."

birds like this LeConte's Sparrow need moist tall grasses and sedges. They would not be able to nest in an area levelled by "mob grazing." 

After last week's post many people contacted me with comments on Savory, grazing management and carbon sequestration. One reader recommended a web page and new book on carbon farming--which you can find right here.

Another reader used this web site on grass-fed beef to make the excellent point that if we would keep our livestock out of feedlots and on grass, the results would be better for storing carbon and protecting water.

Thanks to those who wrote in with their thoughts. This is an important discussion if we are going to find ways to make animal agriculture work in a carbon-conscious world where biodiversity and source water protection are public goods that we must all share responsibility for.

Cattle and the Fate of the Earth, Part I

Depending on who you listen to, livestock are either destroying the planet or saving it. 

For those who argue that livestock are a dead loss to the planet, the primary source of data has always been the 2006 United Nations Food and Agriculture Association report called "Livestock's Long Shadow," which, among other things, blames cattle production for a high proportion of the planet's greenhouse emissions. 

That single document has cast its own long shadow on every subsequent discussion of whether the world would be better off without ruminant livestock. 
from the Cowspiracy website

Then along came Cowspiracy, a popular documentary that stepped up the anti-livestock argument with Indiegogo crowd-funding, a Michael Moore-style narrative, and an all or nothing conclusion that promotes veganism as not merely an environmentally-sustainable lifestyle, but a panacea for our ailing planet.
Cowspiracy, now on Netflix, claims to have used the best science available--or at least the best science supporting their black and white thinking. We can assume that one piece of research they gave a miss was this study published in Nature conducted by a group of scientists working at 40 sites on six continents, including the University of Guelph's Andrew MacDougall. 

The study showed clearly that grassland biodiversity depends upon grazing. In all of the study sites around the world – from the Serengeti to small grasslands in eastern North America -- plant diversity proved to be higher where herbivores, wild or domestic, were able to graze normally.

They also did not check with Tim Flannery, scientist, author of The Weather Makers, and chief commissioner of the Australian Climate Change Commission, who is on record saying that livestock grazing today is a sustainable use of grassland: "If we get the stocking levels right, we get the management techniques right and the management of water and of biodiversity right, I think we can have a very sustainable system of livestock management."

Allan Savory on TED
Meanwhile, early in 2013, holistic grazing guru Allan Savory gave a controversial Ted talk with more than three million views online in which he describes his own panacea for the climate's woes--more grazing. But not just any kind of grazing. Savory is famous for promoting his “holistic range management” brand of grassland management, in which densely packed groups of livestock graze an area for a short duration and then are moved to let it recover—a practice that many livestock producers are adapting under the name “mob grazing.”

In August 2014, however, British pundit and environmentalist George Monbiot, interviewed Savory and dismissed his theories in an article in The Guardian.

Shortly after that, Colorado sustainability promoter Hunter Lovins shot back with her own Guardian op-ed in defence of Savory and “holistic range management”.

OK—let’s stop right there. Following this debate over the past decade has given me a bad case of tennis-spectator neck.

All of the experts make compelling arguments. Even the Cowspiracy film makers have their charm and some of what they say about feedlot agriculture is undeniably true. But they did not look at the wider ecological issues for natural grasslands that scientists and writers like Flannery have explained vis a vis the role livestock plays in replacing absent native grazing animals.

And, as much as I agree with Allan Savory that grazing livestock is an important way for us to restore carbon to our grassland soils, I am not entirely convinced that his system of intensive grazing works everywhere. I may not like the way Monbiot cherry-picks in his critique and dismisses Savory as a quack, but I agree with him on several points about the problems with Savory’s grazing theories. But then I read Hunter Lovins’ defence of Savory and am confused all over again.

That was when I decided to abandon the experts from far away and look for a local one. In part II of “Cattle and the Fate of the Earth”, I ask Saskatchewan rancher, conservationist, and biologist Sue Mihalsky for her thoughts on Savory and his holistic range management system.

Photo Gallery: birds of the Craven and Regina Christmas Bird Counts

Northern Sawhet Owl, courtesy of Laurie Koepke
On a chosen day, each Christmas season, from mid-December to early January, groups of people around North America gather to count the birds in a fifteen mile diameter circle: the Christmas Bird Count or CBC.

I have participated in the Regina CBC since 1985, but in the early '90s I started a Christmas Bird Count centred on the town of Craven. While the number of counters coming out to help at Craven has increased steadily over the years, perhaps the most remarkable change has come from the advent of digital photography.

Bird photography once required thousands of dollars worth of equipment, but recent developments in both digital SLR cameras and the even more affordable super-zoom cameras have made it a lot easier to get telephoto shots of birds.

Here are some photo highlights from the Craven and Regina CBCs. (Thanks to all the photographers who generously agreed to letting me use their photos in this post.)

First Craven, which was held on December 19.

We recorded 37 species (tying our highest record) including a Barrow's Goldeneye (no photo unfortunately), two Townsend's Solitaires and a Spotted Towhee.

Brian Sterenberg took this shot of one of the Townsend's Solitaires--in Phil and Louise Holloway's yard. Louise makes soup for the crew each year and we stop at their place for lunch, watching the many birds at their feeders as we warm up and compare notes for the morning.

Here is a shot of a large raptor that gave us some trouble initially. It flew over very briefly and I mis-identified it as a dark phase red-tailed hawk.

Once everyone got home and looked at their photos, though, it was clear that we had seen an adult Golden Eagle--the gold on the nape is visible in this image by Brian.

White-breasted nuthatches occur at acreages and in the town of Lumsden where people feed birds. Thanks to Val Mann for this photo.

Another common feeder species is the Blue Jay. Nick Selinger, at 12 years of age, the youngest photographer on the count, took this lovely image.

The Northern Shrike, a predatory songbird that eats mice, voles and smaller birds, visits the prairie each winter in small numbers. Thanks to Val Mann for this image.

It was a redpoll year so we counted several hundred on the Craven CBC. This photo of a nice rosy-breasted male was taken by Nick Selinger.

Fran Kerbs managed to find the only two Great Horned Owls on the Craven count. Here is one of the photos she took.

One last image from the Craven CBC--one of the rarest sightings of the day, a Spotted Towhee. This bird should have been hundreds of miles to the south but perhaps had lingered in its breeding precincts after an unusually warm fall and early winter.

Thanks to Hiro Aoki for getting this difficult shot of a very active bird.

Now for some photos from the Regina Christmas Bird Count, held on December 27. The compiler, Brett Quiring, is still getting data from counters but he tells me that it was a banner year for raptors. He is predicting a total well over 40 species of birds including several hawks and owls: Rough-legged Hawk, Bald Eagle, Northern Harrier, Gyrfalcon, Kestrel, a Cooper's Hawk, Merlin, Snowy and Great-horned Owl. 

On December 30, within "count period," birder Laurie Koepke found another owl species in the city--a Northern Sawhet Owl. Here is a photo she was kind enough to share.

But the stars of the Regina count were Rough-legged Hawks. We recorded 37 of them, including 14 in my sector alone. They are congregating near the city outskirts to the south-east, south, and south-west. At one point we pulled our car over along the traffic circle south of Highway 1 and west of Highway 6 and we counted seven in view all at once.

Most were hovering in the air, like this young, hatch-year bird photographed by Brian Sterenberg.

Rough-legged Hawks have been recorded during the Regina count before but not in these numbers. They stay in this area when conditions favour their prey--mice and voles. The warm fall and light snow cover may have allowed numbers of these rodents to persist into December in some areas of the province, and the shallow snow cover allows a hover and pounce hunter like the Rough-legged to find them.

Perhaps the rarest bird on the Regina Count was a Red-bellied Woodpecker, which was good enough to show up at birder Dan Sawatzky's feeder just in time for to be counted. This photo was taken by Val Mann.

Driving the back roads we found a small number of Horned Larks south of the city and west. This image was taken by Nick Selinger, who saw his very first Horned Larks that day.

My favourite winter songbird is the Snow Bunting. It seems almost to relish the cold and stormy weather for you will often find the large flocks swirling and coursing over stubble fields and pastures like larger snow flakes borne on the wind. We came upon two large flocks, one totaling nearly a thousand birds. Brian Sterenberg took this image, showing one in flight and several on the ground feeding.

I will close with this video of a Snow Bunting flock. Though it is a bit rough, it shows some of the restless energy of these birds wintering here in the "south," a relative term because like the Snowy Owls, they breed in the high arctic.

The moon of winter time . . .

This solstice moon, in the dark days of winter, still shines upon the chickadee, the owl, and the redpoll, but St. Jean de Br├ębeuf's old carol--or at least the English translation--is not far off: this is a birdless time of year.

A nesting box in mid-winter, snow on its roof, the entrance filled with nothing but cold air, is a strange figure on the landscape. It looks backward to the summer's rush of life and forward to new tenants in spring, but in the middle--here in the moment when it is hard to imagine either one--all is quiet, stilled to the breath of a sleeping deer mouse.

More than the absence of the swallow and the wren, though, these small domiciles resting beneath December's short light and snow call up thoughts of those who put them up and wait expectantly in spring: the one in the garden, crouched with a hand full of seeds, who stands to follow the small, feathered thing bearing a single twig, heading to the box and stuffing it in the entrance.

I took these photos last week at a farmstead that belongs to my wife's parents. Over the past thirty years, Jack, my father-in-law, has mounted many nest boxes and feeders in and around the aspen bush and garden space surrounding their summer home, near the town of Lanigan.

A civil engineer and road-building public servant as Saskatchewan's Deputy Minister of Highways for most of his career, Jack is now 84 years old, but he tends his acres of vegetables, flowers, trees and sheep's fescue with great love and more energy than most men half his age can muster up on a summer's day.

These are some of the bird nest boxes and feeders he maintains during the growing season. Next summer, when days are long and bright, Jack will be there with his hoe scratching the good earth, watching the bluebirds, wrens, and swallows as they take up residence, and counting the goldfinches at his feeders.

Merry Christmas to all who care for such things--whether you are someone with nest boxes to look after or someone with a thousand acres of native grass to tend.

And a special blessing to the many who have raised their voice this year on behalf of the prairie and the people who take care of it on our behalf.

Working with nature to reduce our emissions

the green gavel goes down to signal Saturday's agreement in Paris

From The Guardian:

After 20 years of fraught meetings, including the past two weeks spent in an exhibition hall on the outskirts of Paris, negotiators from nearly 200 countries signed on to a legal agreement on Saturday evening that set ambitious goals to limit temperature rises and to hold governments to account for reaching those targets.

A child born today might well live to see the year 2100, but at the age of 85 what will her world look like, and how hospitable will it be to human life? Will the average surface temperatures of the Earth be two degrees higher than they are today, four, six?

No one can answer these questions definitively, but the best science we have argues strongly for aiming at the low end of that range. And any chance of that happening will depend on how closely governments around the planet follow the goals set yesterday in Paris.

Those of us living far north of the equator will experience the most dramatic effects of climate change, and regardless of what we do or fail to do, greenhouse gases already in the atmosphere will continue to mess with the thermostat and deliver weather that ranges from dangerous to just plain weird.

Today, a little more than a week away from the winter solstice, cars are splashing through puddles on the streets and roads of Saskatchewan. Katepwe Lake still has thousands of acres of open water playing host to a great gathering of Canada Geese, common goldeneye, and other diving ducks. On the ice edge and in nearby poplar trees, dozens of Bald Eagles are waiting for an easy meal. Last week, local birders counted seventy-two. A spectacle to be sure, but unsettling just the same.

To meet Canada’s commitment in Paris, every province is going to need to do its part and put a price on carbon and other greenhouse gases—either through carbon tax system, as B.C. and Alberta have promised, or through a cap and trade model, which Manitoba, Ontario, and Quebec have announced. Saskatchewan—known as one of the nation’s biggest emitters per capita—has so far done little more than point to its, as yet ineffective, carbon capture mega-project.

But while we wait for that technology to prove that it can make coal “clean”—a dream that many say will never come true—this province has to find its own mix of measures that will, in correct proportion, contribute to our national climate change actions.

To its credit, our government has announced plans to convert our electrical production to fifty per cent solar and wind in fifteen years. A good start, though it would be nice to see some shorter targets in that transition, and a commitment to sustainable and ecologically-sensible siting of wind energy projects.

However, as we wait for some of these important measures to take hold—carbon pricing of some kind and conversion to sustainable alternative energies—there is another side of climate change action for which Saskatchewan is particularly well-positioned.

While engineered carbon capture systems and alternative energies can reduce our emissions through a kind of “technological mitigation,” we sometimes forget that nature provides her own systems of ecological mitigation that we can unleash and encourage in our natural and agricultural landscapes.

Climate change models and estimates of emissions going forward are based on current rates of emissions, including those caused by existing land management practices.

In a province where we have a lot of managed though sparsely populated landscape—forests, grasslands, wetlands, and cropland—even small shifts in land management have the potential to reduce our overall emissions. If we avoid ploughing grasslands, draining wetlands and retain more of our forested cover we will greatly reduce our rate of emissions. And if we restore wetlands and degraded grasslands and plant trees in the right regions we can easily increase the size of the provincial carbon sink and annual sequestration.

prairie wetlands, like this one hosting a Marbled Godwit, can store a lot of carbon

Even smaller changes in land management can help. In an as yet unpublished study on grasslands in Saskatchewan, Alberta, and Manitoba, Dr. Diego Steinaker of the University of Regina found that an additional 0.8 to 1.4 tons of C/ha can be stored simply by reducing grazing from severe to moderate intensity (personal comment).

Saskatchewan is the right place for this kind of climate change action and much more.

We have thousands of private land managers—farmers, ranchers, and forestry companies—whose everyday decisions determine how much carbon the property they manage will hold and how much it will release. These land managers generally possess the skills and equipment required to introduce new climate-friendly land practices. All that is missing is motivation. As things stand, they have no economic incentive to change, and in fact there are many disincentives.

To shift to land use practices that retain more carbon, we will need market instruments and incentive-based public policy deployed across a range of managed landscapes from south to north in the Province. If we connect the right economic and policy minds with the right carbon and soil science minds, we can find ways to work with the private sector and industry to maximize our natural carbon storage systems without causing undue disruption in our land-use industries.

Along the way, if we are lucky, we might arrive at a province with more diverse and resilient landscapes and more adaptive land managers who can help us all face a changing climate.
