Living Lakes Canada

A changing landscape: High elevation fieldwork at Talus Lodge

The summer of 2023 is unfolding as predicted with dire drought conditions worsening across most of British Columbia. The early, rapid snowmelt combined with a hot, dry May set the stage for what’s already declared the worst wildfire year on record in B.C. and across Canada.

According to the provincial government’s zero to five drought level rating system, 82% of B.C. watersheds are sitting at drought level 4 or 5, meaning negative impacts on communities and ecosystems “likely” or “almost certain”. Evidence of drought is seen in increasing water restrictions, low flows in rivers and streams, stranded fish, extreme fire danger, and severe wildfires.

How are alpine headwaters impacted and what does this mean for human communities and ecosystems? Living Lakes Canada’s High Elevation (HE) Monitoring Program aims to help answer these questions. After a successful pilot year in 2022, the program is expanding throughout the East and West Kootenays in 2023, with six stream and nine lake monitoring sites.

Select lodges with the Backcountry Lodges of British Columbia Association (BLBCA) are working with the program to collect valuable alpine data by hosting climate stations, sharing snowpack data, and supporting lake monitoring efforts. On a recent fieldwork trip to Talus Lodge, a participating BLBCA lodge, the HE team witnessed the impacts of climate change. 

Situated on the Continental Great Divide, Talus Lodge stands at an altitude of 2,300 metres amongst a scattering of small alpine lakes. This year, the ice melted off the lakes three weeks earlier than usual, making it the earliest ice-off recording of the last six years. Anecdotally, the lodge’s staff spoke about enjoying early summer ski turns last July, whereas this July the slopes are bare. An archival photo from 1916 shared with the HE team shows a glaciated basin behind Talus Lodge. Today, there are little remnants of this glacier.

During this field trip, the HE team installed monitoring equipment at both the north and south Talus Lakes. This included level and barometric loggers near the shore to measure changes in water level. To measure changes in light and water temperature, pendants were suspended between an anchor at the deepest part of the lake and a buoy floating at the surface. The data collected will inform watershed management and support climate adaptation strategies. All the data is housed on the Columbia Basin Water Hub database. 

The HE Monitoring Program has also launched a citizen science project with the Alpine Club of Canada. Anyone can help by joining the High Elevation Monitoring Program – Living Lakes Canada project on iNaturalist and uploading pictures of flora and fauna they spot within the program’s monitoring locations. These include Kokanee Glacier Provincial Park, Fletcher Lakes, Fishermaiden Lake, Macbeth Icefields, Ben Hur Lake and Shannon Lake in the West Kootenays and Talus Lakes in the East Kootenays. This project is creating a valuable inventory of plant and animal species to better understand climate impacts on alpine biodiversity.

Summer Arrives Early

BLBCA member lodges are transitioning early

With warm weather upon us, many lodges are already open. Don’t miss your chance to grab a spot and get your headstart on a thrilling BC summer.

As the days get warmer and the snow melts away, members of the Backcountry Lodges of British Columbia Association (BLBCA) are preparing for the upcoming summer season. This involves long hours of hard work, planning, and preparation to ensure that visitors have a safe and enjoyable experience.

The first priority of the BLBCA is to ensure that the lodges are safe and comfortable for guests. Members of the BLBCA inspect the buildings for any damage caused by the winter weather. They check electrical systems, plumbing, and other mechanical components to ensure that everything is functioning properly. Additionally, they ensure that furniture, bedding, and other amenities are in good condition, clean and well-maintained.

An essential job of the lodge staff is to ensure that hiking trails are secure and free of obstacles. They carefully remove any downed trees or obstructions in the path, repair damage caused by erosion, and update trail signs for hikers. Lodge staff keep an eye on animal behaviour and may close off some areas or trails if necessary. This helps to ensure the safety of visitors and wildlife while allowing people to enjoy their adventure.

In addition to standard trail maintenance, members of the BLBCA also need to ensure that their lodge is properly stocked for visitors. This includes having a supply of sumptuous food, fuel, and other necessities, such as recreational gear (climbing, hiking, SUPing, mountain biking) needed for whatever activity you are participating in, first-aid kits, and bear spray.

Of course, being prepared for the summer season also means being aware of the potential risks and challenges that may arise, such as wildfires, floods, and other natural disasters. It is essential for lodge members to be familiar with the possibility of human-wildlife encounters and to be well-prepared to address such issues in a humane, safe and responsible way.

Members of the BLBCA emphasize the importance of respecting the natural environment and viewing wildlife in their natural environs. Lodge members encourage visitors to enjoy the beauty of the backcountry without disturbing wildlife. #RecreateResponsibly is an initiative that encourages visitors to take responsibility for their actions and reduce their impact on the environment by practicing “leave no trace” habits.

By taking the necessary steps to prepare for the summer season, members of the BLBCA are ensuring that visitors will have a safe and enjoyable experience in the backcountry. With their commitment to #RecreateResponsibly, lodge members are helping to ensure that visitors can appreciate the beauty of the backcountry while protecting it for future generations.

The Incomappleux

New Conservancy Protects Rare Ecosystem

Walking among the giant cedar, hemlock, and head-high Devil’s club of the Incomappleux River valley south of Glacier National Park, it’s easy to forget that the Pacific Ocean is 500km westward.

The Incomappleux belongs to a unique forest spanning a moist wet belt that’s nourished year round by deep winter snowpacks in the Columbia and Rocky Mountains. Measuring 15,000 sq km in size, it’s known as the Inland Temperate Rainforest, and the newly established Incomappleux Conservancy protects 580 sq kms of it.

This is an important and hard-won conservation victory. Craig Pettitt, a founding director of the Valhalla Wilderness Society, is one of the conservationists who for more than a decade has been championing the protection of the Incomappleux and other remnant patches of inland rainforest like one at the north end of Duncan Lake. If it wasn’t for a blown-out logging road too expensive to repair and a remote location, the timber rights holder Interfor would have already harvested the forests of the upper Incomappleux.

How coastal rainforests have flourished for thousands of years so far from the BC coast results from an interplay of topography, latitude and climate interior that is found in few other places in the world. That’s why for mountain folks like us, the Incomappleux and other forests like it are particularly fascinating. Precipitation in the Incomappleux falls below the threshold of annual precipitation that defines a rainforest, roughly 1400mm per year. However, winter is the difference maker.  Weather systems, laden with Pacific moisture, collide with the interior mountain ranges and delivers a deep snowpack that compensates for the moisture deficit. This creates localized conditions that mimic a rainforest, especially at the foot of mountain slopes where moisture seeps year-round. Such forests have historically been spared from massive fire events, fostering rich biodiversity centuries in the making and allowing trees to live to a thousand years or more. In terms of species mix, biodiversity, climate, and feel, these forests are more Walbran Valley on Vancouver Island’s West Coast than the interior mountain ranges where pockets of this ecosystem thrive. So big deal, why protect them?  Well, such forests can generate tourism – people will travel to visit big trees. Tall tree tourism has become a thing in Port Renfrew thanks to the Avatar Grove.

But more importantly is that biodiversity is key for planetary health, and the Inland Temperate Rainforest is a richly biodiverse frontier of scientific discovery. In the early 2000s University of Alberta botanist Toby Spribille studied lichens in the upper Incomappleux River valley and catalogued more than 280 species, nine of them new to science. A survey of mushrooms in the Incomappleux identified 50 species, half of which are normally found only in coastal forests.

Dwayne Coxson, a University of Northern BC lichenologist, and botanists Trevor Goward and Curtis Bjork, both affiliated with UBC’s Beatty Biodiversity Museum, have been studying the interior rainforests of the Robson Valley, roughly between the communities of Dome Creek and Upper Fraser on the Yellowhead Highway. In an area that includes both Ancient Forest/ Chun T’oh Whudujut Provincial Park and the 50,000-hectare Sugar Bowl-Grizzly Den Protected Area, the team has catalogued more than 2,400 plant species, including dozens of new discoveries. What’s even more surprising is that not all of them are “mosses and lichens,” says Coxson. “Some of them are vascular plants [a broad group of plants with tissues for conducting water and minerals – like fir trees or wildflowers.] It shows just how little we know about this ecosystem,” says Coxson. “Globally it’s a very unique ecosystem.”

Similar temperate rainforests are found this far inland in only in two other places, southern Siberia and Russia’s far east. According to Coxson, though scientific understanding of these rainforests has advanced, precautionary land use decisions in BC have not kept pace.

This forest once covered more than 160,000 square kilometres and stretched 1100km from central Idaho through BC’s mountainous interior as far north Prince George. According to some estimates, more than a quarter of this rainforest has been clear-cut logged and less than 10% has been protected.

That’s why the Incomappleux Conservancy, which came about after Interfor gave up 750 sq km of its forest tenure in the area, is worth celebrating. The Nature Conservancy of Canada brokered the deal, which includes support and funding from Teck Resources, several foundations, the federal government and individual donors. It also required the participation of First Nations in whose territory the valley lies. In reality, few of us will ever see the Incomappleux Valley. But that’s okay; knowing that this treasure exists is reward enough.
