Ecological Techniques for River Restoration & Erosion Control – Course in Grand Forks September 17&18

Selkirk College is hosting a course to help landowners, restoration practitioners and natural resource managers understand, develop and implement erosion control, habitat improvement, and water quality protection using plants!

This 2 day course is an in-depth review of soil bioengineering techniques and options

involved in restoration and reclamation of damaged ecosystems using a combination of structural materials, vegetative cuttings and other specialized techniques. Soil engineering is an applied science that uses live plant materials to perform an engineering function such as slope stabilization, soil erosion or seepage control.

2 classes: Sep 17 & 18, Thu & Fri 8:30 am-4 pm

We have the opportunity to make the Bioengineering course even more affordable ($110) for 6 to 7 participants who are willing to join us on the Sion slope restoration project in the next month or so, thanks to the Granby Wilderness Society and Electoral Area D / Rural Grand Forks director Roly Russell. When you register for the course (at full price), notify me that you intend to work-trade and we will provide a honorarium once you have spent a day (or two half days) with us applying what you learned in the course! There will also be a limited number of bursaries available to farmers, landowners, and stewardship group members who intend to use the skills on their own projects – please contact me for more details.
Please register for the course at Selkirk College, Grand Forks by next week if possible, and forward this note to any contacts you think would value taking it:

On this Friday, September 4 we will be gathering stakes and cuttings for the Sion slope project, meeting at 8:00 at the Grand Forks RDKB and leaving for the field by 9:00 – done at 12:30 or 3:00 depending on when you would like to leave. Looking forward to seeing you in the field!

About the instructor:

Instructor David Polster brings a wealth of experience stabilizing slopes and restoring ecosystems using applied ecology. David is a plant ecologist with over 30 years of experience in vegetation studies, reclamation and invasive species management.  He graduated from the University of Victoria with an Honours Bachelor of Science degree in 1975 and a Master of Science degree in 1977.  He has developed a wide variety of reclamation techniques for steep/unstable slopes as well as techniques for the re-establishment of riparian and aquatic habitats.  He is the past-president of the Canadian Land Reclamation Association.  He is the treasurer for the B.C. Chapter of the Society for Ecological Restoration and serves as the alternate mining representative on the board of the Invasive Plant Council of B.C.  For the past 19 years he has lived with his wife, Genevieve Singleton and four children in Duncan, BC.

Dave has provided on-site design and direction in the development of reclamation and bioengineering systems for restoration of severely damaged ecosystems.  He served as the environmental supervisor for CP Rail’s massive Roger’s Pass Project.  He was responsible for developing the bioengineering systems that have successfully revegetated a portion of the Point Grey cliffs at UBC.  Dave has prepared reclamation plans for numerous mines, quarries and gravel pits in Canada.  He pioneered the concept of successional reclamation where the aim of the reclamation program is the re-integration of the disturbed site into the natural processes of vegetation succession.  He has applied his knowledge in ecology to solving problems of unwanted and invasive vegetation.  He has also authored numerous papers on these topics.

 

 

Kettle River Q&A: Responding to drought with water conservation

We’re going to need to work together on this one. What helps us conserve water during a drought, and why do we not take more steps to conserve water?

At a recent meeting of water suppliers and municipalities in Grand Forks to discuss the drought situation and potential responses, I introduced some ideas about what motivates water conservation, framed as personal reasons people don’t conserve. We had a good conversation about what these ideas mean for how we develop the short and long term water conservation strategies – more on that later.

“It’s not a problem.” I’ve heard this quite a bit on social media, letters to the editor, and even public meetings. People aren’t aware of their connection between their water use and the state of the Kettle River, or they don’t believe that they have enough impact, either way, to start conserving.

There certainly is a problem. The Kettle River and many of its tributaries are flowing very low right now, after a low snowpack and early spring freshet. The region (like much of southern B.C.) is at a Level 4 drought, and any excess water use from surface or ground water reduces available water for fish, water quality, aquatic ecosystems, and downstream use.

This seems like it should be easy to fix – more education! More signs, more media coverage, more pamphlets. Many of the water suppliers are already working on this. Awareness certainly helps, but it turns out there are many more barriers in the way to water conservation. Indeed, awareness without other measures will only motivate change for some people.

“No restrictions are in place.” According to water supply managers at the meeting, restrictions are having an impact on overall water use, with many people even going further to allow their lawns to go dormant.

However, the provincial government has so far only requested voluntary reductions of 30% or more, and only some of the water suppliers have a drought response plan that restricts outdoor water use. Furthermore, provincial regulations currently only affect surface water licences, even though using ground water from sand and gravel aquifers has a direct impact on surface water levels.

New regulations coming under the Water Sustainability Act could go a long way to improve our drought response, together with active efforts at compliance and enforcement by water suppliers and local and provincial governments. They will need your input to get these regulations right – future columns will highlight proposed changes.

“My neighbours are all still watering.” The ‘neighbour effect’ cannot be underestimated. People are highly motivated by peer pressure and shared ideas of right and wrong. So taking visible steps to reduce water use – allowing the lawn to go dormant, installing drip irrigation, planting a dryland (xeriscape) garden – will go a long way to shift attitudes in your neighbourhood.

“I pay the same no matter how much I use.” Paying a fixed fee for any utility or resource just doesn’t make sense to me, especially when that resource is scarce and connected to many other valuable uses.

People who save water will also value saving money on their utility bill, and people who want to use more can feel good about paying their fair share. It will be up to water suppliers how they make this work, through water meters or through more radical measures such as paying people to remove lawns or install drip irrigation and greywater systems.

“I don’t know how to…” Fill in the blank – reprogram the irrigation timer, install drip irrigation, plant a xeriscape garden. Helping people learn new skills of water conservation will not only help them save water, it will ripple outwards through the neighbour effect. So water suppliers should start to work together on building skills for water conservation with demonstration gardens, hands-on workshops, or in-house instruction. Community members could also share their successes through public demonstrations and garden tours.

“It’s too expensive, complex, or inconvenient to change my system.” This turns out to be a big one, because large farms and businesses have complex, expensive water and irrigation systems already in place. They also use a lot of water compared to households and domestic gardens. It makes sense to support farmers and others in installing more efficient irrigation equipment, sharing costs or providing incentives through programs like Environmental Farm Plan.

Bringing all of this together will take time, effort, and a shared understanding of the role of water conservation in a healthy, resilient Kettle River Watershed. We will develop long-term strategies at future meetings of water suppliers. How will you fit in?
