Project Profile & Lessons Learned: Goldway Road Restoration

Goldway Road Restoration - Chu Cho Environmental LLP

In 2018 Chu Cho Environmental identified several candidate roadways for restoration within the Chase caribou herd range with input from forest licensees, caribou biologists, and Tsay Keh Dene Nation. In total, Chu Cho Environmental and Tsay Keh Dene Nation have now completed restoration work on 3 roads within the Chase caribou herd boundary since 2019. Collectively, these projects have been a part of the larger Chase Caribou Road Restoration Program (CCRRP), with the Goldway road being the most recent restoration project.

Planted Seedling – Chu Cho Environmental LLP

Sean Rapai of Chu Cho Environmental shares the challenges and lessons learned on this project including those around permitting, post-treatment monitoring and longer-term considerations.

Permitting: The historical presence of anadromous salmon in Johanson Creek, combined with the presence of bull trout and steelhead trout impacted the window for fording Johanson Creek with an excavator. It was necessary to submit an application to Fisheries and Oceans Canada (DFO) with the proposed plan and timing window of the work. The Letter of Advice was eventually secured which indicated work could proceed as planned. Best practices were outlined as well as recommendations for the fording process. This proved challenging, but the project did receive approval from DFO.

Monitoring: Ecological restoration treatments could take five or more years to begin to show results. With monitoring, we are attempting to answer a long-term set of questions and return to the site in the years immediately following restoration. Monitoring can be very costly as assessing control treatments is often restricted to the use of a helicopter. Chu Cho Environmental investigated the feasibility of using remotely piloted aircrafts (drones) as a more cost-effective method of monitoring restored areas in the short-term. This method was explored for monitoring remote roadways and restored areas.

Drone-based monitoring: Based on recommendations from 2021, Chu Cho Environmental deployed drone-based remote-sensing surveys to monitor vegetation using derived NDVI indices. Data was collected to a resolution of 1 m2 and can be paired with future surveys to track vegetation establishment and growth along large stretches of the road. While the use of a drone as a monitoring tool in this restoration program is in the preliminary stages, the ease of data collection and results suggest this is a viable means of evaluating vegetation indices on pre and post restoration roadways.

Stability of ecological restoration treatments: Year one monitoring of the ecological restoration techniques used in the project showed strong persistence of these treatments. The rough-and-loose soil contouring was stable, intact, and holding water, and planted seedlings had a high survival rate.

Recontouring inhibits human access: Areas recontoured with the rough-and-loose treatment had the least evidence of use by humans, including those on horseback. Aggressive recontouring of roads at strategic locations may be considered a viable tool to discourage trail usage and eliminate all-terrain vehicle use.

Snow alters access by motorized vehicles: Snowmobile use of the road was observed when the snow had accumulated above restoration efforts (i.e., above height of felled trees and mounds). While the effect of such anthropogenic use has yet to be studied here, considerations may be required for future restoration efforts or access management restrictions on snowmobile use.

Functional restoration: Felled trees were intact, and it was observed that larger diameter trees felled from steep cut banks created better movement barriers. Conversely, smaller diameter trees felled for functional restoration did not provide as good of a visual and physical barrier and is suggested that when small diameter trees are the only available source, they are felled in stacks. High survival of planted seedlings, following mechanical site preparation, suggests that tree planting is likely to provide visual screening over the long term, and may represent a more effective long term means of functionally restoring these roadways.

The Goldway road lies within the range of the Chase caribou (Rangifer tarandus caribou) herd, which is considered by the federal government of Canada to be part of the Northern group of the Southern Mountain population of Woodland caribou. This herd is listed as threatened on Schedule 1 of the Species At Risk Act (SARA).

Project Profile & Lessons Learned: Tweedsmuir Caribou Winter Range – Chelaslie Road Restoration

Directly east of Tweedsmuir Park, there is an area caribou utilize as their core low-elevation winter habitat and as a migration route between winter and summer habitat. It is currently heavily impacted by human-caused disturbance such as forest harvesting and associated roads. The BC Ministries of Water, Land and Resource Stewardship and of Forests have been working on a project that aims to benefit the Tweedsmuir-Entiako caribou (TEC) herd through restoration of linear disturbances in the Chelaslie migration corridor (CMC). The project includes many partners, including Cheslatta Carrier Nation and the Society for Ecosystem Restoration in Northern BC (SERN BC), working on the restoration of roads and fire guards that are no longer required. Over the 2021 and 2022 seasons, ecological and functional restoration treatments were applied to over 54 km of road and fire guard. An additional 22 km of road has been effectively deactivated through the treatment of access roads. Restoration efforts will continue in 2023, through machine work on legacy roads, planting of roads and wildfire guard, and monitoring.

Restoration activities incorporate ecological restoration, which includes site preparation and conifer planting to recover habitat suitable for caribou; and, functional restoration, which includes activities such as woody debris spread, tree felling, mounding, and berm creation. These barriers are intended to reduce line of sight and make roads more difficult to travel along, which is important to eliminate human access and reduce predator mobility. The project utilized vegetation surveys, assessments for mobility, trail cameras, drone imagery, and GPS collars to monitor the short- and long-term outcomes of restoration treatments on access, vegetation, caribou use, and use by other wildlife.

Anne-Marie Roberts, Tweedsmuir Caribou Herd Program lead with the BC Ministry of Water, Lands and Resource Stewardship (WLRS) and Joanna Lee, BC Conservation Foundation (BCCF) contractor with WLRS share some lessons learned on the project so far.

Review of work to date: During the first year, the project was scoped out based on previous work and from projects in other areas of British Columbia and Western Canada. This allowed for beneficial streamlining of some of the work around restoration treatments and implementation development. Learnings from the initial year of the project also helped scope subsequent workplans, training, and reporting.

On Site Discussion: While this project utilized an experienced Project/Site manager on the machine work, a team site visit was held early before the machine work began to review implementation. Representatives from the BC Ministry of Water, Land and Resource Stewardship (Nadina Forest District + Skeena Region), Forest Carbon Initiative, Cheslatta Carrier Nation, and HCTF were in attendance and visited roads completed in previous years as well as roads to be completed in 2022 and had in-depth on-site discussions about restoration treatments and goals. This was an effective use of time to ensure that prescriptions were communicated and understood well by all involved. It also resulted in a better understanding from the machine operators that were newer to this type of project to know what the project was intending to achieve (i.e., plant-able spots, functional treatments aimed to reduce sightlines and minimize access and ease of movement).

Remote Cameras: On a more logistical note, cameras deployed in remote areas were a significant investment in time and money to deploy, check and process. Ensuring that cameras are protected as much as possible (bear boxes and possibly locks) is important to protecting the investment in that data.

Partners and Stakeholders: Working with First Nations and stakeholders is unique to each region and caribou herd, and it is essential to include inputs from different groups to this type of project. Adequate time must be set aside for meaningful input and to develop real partnerships for ongoing restoration. This will be important in the long-term implementation of restoration treatments. Through deep commitment to working together there has been significant contribution from First Nation partners to this project, caribou recovery, and in building capacity to support and lead components of this work.

World Caribou Day 2023: Discover the Canadian Caribou Subspecies

Klinse-Za Caribou Herd – Mount Rochfort

Here in British Columbia on World Caribou Day we are thankful that our forests and mountains are still home to the Woodland subspecies of caribou, including Boreal, Northern and Southern mountain caribou.

For those living in the regions where caribou roam, these creatures are a lens into the health and connectivity of the overall ecosystem. They are both an umbrella species (their health indicates the health of the ecosystem as a whole) and indicator species (easily impacted by changes to their habitat). Caribou are also considered a cultural keystone species due to their immense importance to Indigenous peoples across Canada. This video by Chu Cho Environmental illustrates the deep cultural relationship between the Tsay Keh Dene people and Wedzih, the caribou:

All caribou in British Columbia are under threat of population declines from habitat loss and the altering and fragmentation of habitat. For many subpopulations habitat degradation has already taken a toll on individual herds as First Nations, environmental non-profits, teams from the Province of British Columbia and Government of Canada, and some industry partners work together to help restore or maintain populations that are threatened or endangered.

Arguably the most important part of recovering caribou populations is habitat protection and restoration. The Caribou Habitat Restoration Fund (CHRF) is proud to support the continued restoration of roads, seismic lines and other linear disturbances to help limit human and predator access into habitat of threatened herds.

World Caribou Day

June 6th is World Caribou Day! (photo by Jean-Simon Begin)

Today marks the first annual World Caribou Day! Alongside the Caribou Conservation Breeding Foundation, Habitat Conservation Trust Foundation is celebrating this iconic Canadian species. Take the opportunity to learn about the threats facing caribou and the conservation works going on in British Columbia and across the world to protect the species for generations to come.

A few facts about Caribou! Caribou and Reindeer are two names for the same species and occupy arctic, sub-arctic, boreal, and sub-boral ecosystems across North America and Eurasia respectively. These groups are further separated into subspecies, with woodland caribou, Peary caribou, Porcupine caribou, and barren-ground caribou comprising the species spread across northern Canada. Caribou are the only species of deer in which both the male and female have antlers and they use these antlers to brush away snow as they search for food and to defend themselves. The species is supremely well adapted to cold climates, with a double-layered coat of fur, a hairy nose to minimize heat loss, large hooves that let them walk softly atop snow (like snowshoes), and which make clicking noises with each step which helps the herd stick together even when visibility is poor due to blizzards or thick fog. Caribou are herbivores and rely on grasses, leaves, mushrooms, and flowering plants in the summer, while during the winter their diet consists of lichen, small shrubs, and sedges. Caribou eat 9 to 18 lbs. of vegetation a day and herds may migrate over 1,000 kilometres in search of food and habitat. Barren-ground caribou have the longest migration of any land mammal on earth!

Caribou Info (by Caribou Conservation Breeding Program)

Caribou populations are declining globally and have sustained a 40% overall decline over the last 10-30 years. The International Union for Conservation of Nature (IUNC) lists the species as vulnerable on its Red List of Threatened Species. Within Canada, the conservation status is assessed for each caribou population, with many listed as threatened or endangered. Although caribou abundance naturally fluctuates, those natural cycles are being impacted by human-induced factors. Resource development, hydroelectric development, fire suppression, urban sprawl, and agriculture have fragmented and altered much of caribou habitat. While highways, roads, and cut lines further disrupt migration routes and create corridors that allow predators, such as wolves, to infiltrate caribou habitats more easily, increasing their vulnerability to predation. Climate change resulting in rising temperatures, shifting precipitation patterns and changes in wildfire ecology impact both caribou habitat quality and availability. Climate impacts also shift the distribution and viability of infectious pathogens and place caribou populations at risk of contracting novel diseases.

Project #5-346 – North Thompson Caribou Recovery Access Management Project

The Habitat Conservation Trust (HCTF) is supporting the restoration and conservation of British Columbia’s caribou populations through the Caribou Habitat Restoration Fund (CHRF). The CHRF grant was set up for the purpose of restoring high-value habitat for caribou in British Columbia using functional and ecological restoration methods. To address factors such as urbanization, forestry, oil and gas, mining, and roadbuilding work, which altered caribou habitat, the CHRF funds projects that plant trees to restore areas to a pre-disturbed state, block former roads and other linear features such as seismic lines (corridors cleared of vegetation to assist oil and gas exploration) to reduce predator access and restore food sources such as lichen within protected caribou habitats.

Funding for the CHRF is provided by the British Columbian and federal governments with $8.5 million committed by the province in 2018 and an additional $5 million from the federal government pledged in 2021. Through the CHRF, HCTF is currently supporting 14 caribou habitat restoration projects across the province including the Mount Rochfort project, led by the Nîkanêse Wah tzee Stewardship Society in co-operation with Wildlife Infometrics and Canadian Forest Products Ltd. With the support of a $192,617 grant, habitat is being restored along a 156 km stretch of road in the Klinse-za caribou-herd area, adding about 7,865 hectares of habitat and contributing to a total of 26,322 hectares of connected caribou range. A full list of current CHRF-funded projects occurring across BC is available on the HCTF webpage.

Another project funded through the Caribou Habitat Restoration Fund and led by Tsay Keh Dene Nation-owned Chu Cho Environmental is the Chase Caribou Road Restoration Program. See the following videos detailing the habitat restoration project benefiting the Chase Caribou Range.
