Meet Molly – Vancouver Island Marmot Super Mom

Earlier this year, a field crew on an inventory trip made a surprising, and welcome, discovery in Strathcona Park . A new marmot mom, Molly, had six pups! Veteran Field Crew member Jordan Cormack managed to snap some photos of the busy mom and her brood. Vancouver Island Marmots usually have 3 or 4 pups once every second year and field teams have only seen litters of six weened pups a few times, never in Strathcona Park.

Less than 10 years ago, no marmots remained in Strathcona Park, and it has been a struggle at times to re-establish the species there. Historically, the Park was part of the Vancouver Island Marmot’s range, but the species was extirpated from the region sometime during the 1990s, with only a small handful surviving nearby at Mount Washington Alpine Resort. Re-establishing the marmot in the Park is an important part of the Recovery Plan for the species. In addition to being a large protected area within the marmot’s former range, marmot habitat in the Park may be more resilient as our climate changes.

Re-introducing a vanished species is never simple, and Strathcona Park is particularly challenging. Weather and terrain in the Park are harsher than in the marmots’ more southern colonies. Even more difficult was the loss of marmot “infrastructure” – burrows and hibernacula – that disappeared when the marmots were extirpated from the Park.

It is immensely rewarding to see a large litter of wild-born pups there. It suggests that Molly must have great body condition, which in turn means she must have had a good hibernaculum, and likely the support of a small, but functional, colony at her home on Castlecrag.

Molly’s litter is a small step towards the recovery of her species in Strathcona, and a hopeful sign that the species is beginning to find ways to thrive in this beautiful and rugged wilderness. That Molly and her brood have this chance at all is due to the partners, donors, and funders, including the Habitat Conservation Trust Foundation, that have supported re-introduction work.

A huge thank you to Adam Taylor, Executive Director of the Marmot Recovery Foundation, for sharing this project update with us. The Reestablishing Vancouver Island Marmots in Strathcona Provincial Park project is funded in part through HCTF’s North Island Conservation Fund.

Bats in Your Belfry?

A California myotis (Myotis californicus) photographed in a building roost.

Have you noticed more bats around your house or property? You are not alone! Midsummer is the time when landowners typically notice more bat activity, may have bats flying into their house, and occasionally find a bat on the ground or roosting in unusual locations. These surprise visitors are usually the young pups. “In July and August, pups are learning to fly, and their early efforts may land them in locations where they are more likely to come in contact with humans“, says Mandy Kellner, biologist and coordinator with the BC Community Bat Program.

If you find a bat, alive or dead, never touch it with your bare hands. Bats in BC have very low levels of rabies infection, but any risk of transmission should not be treated lightly. Contact a doctor or veterinarian if a person or pet could have come into direct contact
(bitten, scratched etc.) with a bat.

Landowners can visit the BC Community Bat Program’s website (www.bcbats.ca) for information on safely moving a bat if necessary and to report bat sightings. The Program also has a 1-800 number (1-855-9BC-BATS) with regional coordinators across the province able to offer advice. The Program is also currently seeking reports of mortalities at bat colonies in houses, barns, or bat houses. The BC Community Bat Program and their support with batty matters is funded by the Habitat Conservation Trust Foundation, the Forest Enhancement Society of BC, and the Government of BC. Female bats gather in maternity colonies in early summer, where they will remain until the pups are ready to fly. Some species of bats have adapted to live in human structures, and colonies may be found under roofs or siding, or in attics, barns, or other buildings. Having bats is viewed as a benefit by some landowners, who appreciate the insect control. Others may prefer to exclude the bats. Under the BC Wildlife Act, it is illegal to exterminate or harm bats, and exclusion can only be done in the fall and winter after it is determined that the bats are no longer in the building. Again, the BC Community Bat Program can offer advice and support. To find out more, download the “Managing Bats in Buildings” booklet, or contact your local Community Bat Program by calling 1-855-9BC-BATS.

Thanks to the BC Community Bat Program for providing this update.

New Research Into Managing Mange (with photos that will have you saying “awww” instead of “eww”)

You don’t expect to get warm fuzzies from a project about mange, until you receive photos like this:

 

This little lamb is part of a herd of California bighorns were the test subjects in a project testing treatments for Psoroptes ovis, a microscopic mite that’s been causing big problems for some BC bighorns.

The first confirmed case of this highly contagious parasite was in the Similkameen Valley in 2011. Psoroptes ovis, also known as sheep scab or psoroptic mange, is highly irritating to infected sheep, causing ear crusting and in some individuals, itchiness that drives them to rub out their haircoat and develop sores. Psoroptic mange is thought to be at least partially responsible in the decline of the one infested bighorn herd in BC and numerous infested herds in the United States.

Not so cute: a closeup of the crusting caused by psoroptic mange on one of the bighorn sheep study subjects.

Prior to this project being conducted, the only way to effectively treat Psoroptes was through multiple applications of every animal in a herd of an anti-parasitic – hardly a practical solution when dealing with wild animals. The goal of this HCTF-funded project, carried out as a joint effort between the University of Saskatchewan, the Government of British Columbia, and the Penticton Indian Band, was to try to find a treatment that could be delivered in a long acting single dose, greatly reducing both animal stress and costs associated with having to capture every wild sheep in a herd multiple times.

Onesie blindfolds are used to keep the sheep calm while they are weighed and treated.

 

The first drug to be tested was LongrangeTM, an extended-release eprinomectin solution that had shown promise during pilot studies. In the winter of 2017, Adam and his team captured 18 naturally Psoroptes-infested bighorns from Penticton Indian Band lands and housed them in one of two purpose-built wildlife enclosures. While in the enclosures, the sheep were fed, watered and carefully monitored, with sampling monthly to track the success of the treatment. While there, some gave birth to bouncing bighorn lambs. Unfortunately, the LongrangeTM treatment proved ineffective, so Adam decided to try a second drug: fluralaner. In Canada, fluralaner is licenced under the brand name BravectoTM as an anti-tick and flea treatment for cats and dogs. Both topical and oral formulations were trialled and the oral formulation worked! No live mites were found in any ear crust samples collected from orally-treated sheep one month after treatment and ear lesions were also significantly reduced.

This project is also investigating where the infection in the Canadian herd originated and evaluating different methods of detecting disease in asymptomatic carriers to help prevent further spread of this parasite into currently uninfested Canadian herds.

Science in the field

Further research is needed to find out how long Bravecto-treated individuals would be protected from reinfection and to ensure drug safety at different dosages and for different animals before moving forward with administering the drug in the wild, but this project’s findings are a significant step forward in discovering an effective tool for managing – or even eradicating – psoroptic mange in bighorn sheep throughout North America. The bighorn sheep subjects were successfully released back into the wild (mange-free) at the conclusion of the testing.

BC Parks Contributes $30K from Licence Plate Sales to HCTF GO Grants Program

Environment Minister George Heyman announces BC Parks will contribute $30,000 to HCTF's GO Grants program.

VICTORIA – To get more students out of the classroom and into the great outdoors, BC Parks is contributing $30,000 from the sales of specialty licence plates to the Habitat Conservation Trust Foundation’s (HCTF) GO Grants Program.

“By supporting the GO Grants Program, we are giving youth a chance to experience nature and gain a unique learning experience in some of the most beautiful provincial parks B.C. has to offer,” said George Heyman, Minister of the Environment and Climate Change Strategy. “We hope a new generation of young people will form a lifelong attachment to our province’s diverse and rich natural environment.”

Minister Heyman announces GO Grants funding

The GO Grants Program provides funding for school field trips to provincial parks, and other natural areas, so students can learn about B.C.’s fish and wildlife habitats, as well as biodiversity, while fostering an appreciation for the environment. The trips give youth a chance to spend time outdoors and participate in hands-on learning activities, such as beach seining, releasing salmon fry, nature scavenger hunts, and plant and animal identification.

Last year, licence-plate funding supported outdoor learning in provincial parks for more than 700 students. Up to 2,500 students are anticipated to go on field trips this year, as demand for the program is at an all-time high.

“We want every student in B.C. to have the opportunity to experience first-hand the incredible diversity of animals and plants that are part of their communities,” said HCTF education committee member Ken Ashley. “BC Parks’ contribution will enable an additional 2,100 students to participate this year. Connecting kids to nature helps build a conservation ethic that is critical to protecting B.C.’s biodiversity for future generations.”

Dr. Ken Ashley speaks on behalf of HCTF at GO Grants at Goldstream Provincial Park

The B.C. government is reinvesting all net proceeds from the sale and ongoing renewals of BC Parks licence plates back into provincial parks, to ensure action is taken to protect the environment and achieve conservation goals.

Project Evaluation: Spring Site Visits

Dutch Creek Columbia Lake as viewed from the Hoodoos property
By Kathryn Martell and Christina Waddle

Project evaluation is a core component of HCTF’s grant programs. In addition to a thorough review of proposals and project reports, we conduct more in-depth evaluations of several projects each year. This assessment combines a detailed review of both financial and biological components of a project, ranging from questions about a project’s bookkeeping processes to a field day with the project leader to see the activities “on the ground”. These site visits provide us with an opportunity to better understand a project’s challenges and successes, to evaluate our conservation return on investment, and—best of all—to spend time with our project leaders somewhere outside in wild BC with an opportunity for them to tell us more about the projects they are passionate about.

One of the new interpretive signs funded with an HCTF Land Stewardship grant at NCC”s Dutch Creek Hoodoos property

HCTF staff had the opportunity to visit two of our continuing projects this spring. Our Conservation Specialist Christina Waddle attended the Official Trail Opening Ceremony at the Dutch Creek Hoodoos Conservation Area owned by the Nature Conservancy of Canada (NCC). Richard Klafki, Canadian Rocky Mountains Program Director for NCC, showed Christina some of the work that’s been accomplished with the Land Stewardship Grant from HCTF. This project included marking and improving the main loop trail and discouraging use of other informal trails on the property through directional signage and fencing. The other main component of the project was the design and installation of five educational interpretive panels. This will help meet NCC’s management goals for the property which include protection in perpetuity, providing a quality site appreciation experience, while limiting the effects of recreation on native vegetation and wildlife.

Evaluation Manager Kathryn Martell and Finance Officer Jade Neilson headed over to the Lower Mainland to meet up with provincial sturgeon specialist Erin Stoddard and his field crew for a day on the Fraser River. Now in its sixth year, the Lower Fraser White Sturgeon Telemetry Study is conducting long-term monitoring of adult sturgeon to gain a better understanding of movement patterns and habitat use of this Red-listed species in the Lower Fraser, Pitt, and Harrison Rivers. Although White Sturgeon is considered at risk, there is a limited catch-and-release fishery on the Lower Fraser River; a licence surcharge supports a dedicated HCTF fund for sturgeon research and recovery efforts.

HCTF Finance Officer Jade Neilson and project field technician Garrett enjoy some sunshine as they journey from one site to another.

Jade and Kathryn had a great day out on the water, with high flood conditions making it both challenging and interesting to retrieve and re-deploy the data loggers that record movements of individual sturgeon using acoustic tracking devices. It is surprising how little we know about this long-lived, large, prehistoric fish that is so important to local First Nations. This project is the first ever long-term telemetry study of sturgeon habitat use on lower Fraser River White Sturgeon, and it is already providing critical information about over-wintering sites, spawning areas, and development impacts, that is being used to improve fisheries and habitat management. In between hauling heavy equipment in and out of the boat, we had a chance to see some of the critical spawning areas being studied; to understand much more about the project’s study design, and how Erin and his crew have responded to many challenges (such as, what to do when your data logger is buried under 3 tonnes of log boom?) and learn about some of the complications of studying a fish that can live twice as long as humans and travel more than 125 km upstream and downstream each year in the ever-changing conditions of a large river system.

Field technician Garret preps a data logger before submerging in the river. IN the background, you can see an example of the battering some of these frames take from log booms.

Thank you to both Richard, Erin and Garrett for showing our staff the conservation work being accomplished with HCTF grants.

Dough for Does – Grants, Donations and Volunteers Support the Southern Interior Mule Deer Project

Southern Interior Mule Deer project volunteers collar a mule deer doe and use ultrasound to determine if she's pregnant.

A new, large-scale research project, involving multiple agencies and universities, has started to tackle one of the most pressing needs in wildlife management in British Columbia – how to understand and reverse declines of mule deer in the Southern Interior. With contributions from Indigenous people, the public, stakeholders, and industry, this project brings together cutting-edge research on deer ecology with multiple partnerships to advance both evidence and cooperative-based approaches to wildlife conservation.

“Mule deer declines have been a concern in portions of the southern interior since the 1960s, and decades of hunting regulation change have not reversed the declines,” said Jesse Zeman, Director of Fish and Wildlife Restoration, BC Wildlife Federation.

A combination of fire suppression, timber extraction, highways, urban sprawl and other factors affect the movement and size of mule deer populations in the Southern Interior of B.C. Sophie Gilbert, an Assistant Professor at the University of Idaho and co-investigator on the project, said, “in addition to landscape change, things like increases in competitor or predator species may also be affecting mule deer, as we’ve seen in other parts of western North America, and we want to identify which drivers are most important in the Southern Interior.”

Mule deer are essential for food security, Syilx (Okanagan) cultural practice and knowledge transfer, hunter opportunity, and are a ‘canary in the coal mine’ for B.C.’s ecosystems.

“What we have heard from Indigenous communities, ecologists, and resident hunters is that the decline of mule deer matters to them and the status quo is no longer sufficient,” said Dr. Adam T. Ford, Assistant Professor and Canada Research Chair in Wildlife Restoration Ecology at the University of British Columbia, Okanagan Campus and co-investigator on the project. “It is time we bring more science to bear on issues affecting wildlife in B.C.”

The B.C. Fish and Wildlife Branch, in collaboration with the BC Wildlife Federation, Okanagan Nation Alliance, volunteers and researchers at the University of British Columbia, and the University of Idaho, placed GPS tracking collars on 64 adult female mule deer (does) in the following areas: Kettle-Granby, Peachland/Garnet Valley, and Cache Creek/Elephant Hill fire.

There are an additional 33 adult female mule deer collared in the Kootenay study area.

Of the 64 deer captured in 2018, ultrasounds were used to assess pregnancy rates and general health on 56 does greater than one year of age. The project team found a 98 percent pregnancy rate, at least 80 percent of those does were carrying twins. Does and their offspring (fawns) are what drive deer population change, which is why the project is focusing on them.

The GPS collars in the Kettle-Granby, Peachland/Garnet Valley, and Cache Creek study areas track the deer movements every 4.25 hours and provide information on the deers’ habitat use, how they move across the landscape, which areas they avoid, when and how they die. When a collar is no longer moving, a message gets sent to the project team which allows them to investigate factors contributing to the animal’s death.

In addition to the collars, at least 200 remote cameras will be deployed in the project areas to provide an understanding of how other animals (predators, prey, and people) interact with mule deer. The cameras will also provide recruitment data (fawn survival) and sex ratios (buck: doe), and potentially help count mule deer and other large mammals.

This fall the group expects to place GPS collars on a minimum of 60 mule deer fawns and will also incorporate vegetation monitoring (food availability).

To date, nearly $300,000 in direct funding has been contributed to the project through multiple sources including, BC Wildlife Federation Clubs and partners, corporate donors, Habitat Conservation Trust Foundation, B.C. Fish and Wildlife Branch, Ministry of Transportation, and B.C. Timber Sales. The project has also confirmed over $500,000 of in-kind support from collaborators, particularly project volunteers and the University of B.C. Okanagan and University of Idaho.

“While there has been tremendous community support, the project still requires additional financial and in-kind support to fund the remaining four years of the project,” said Jesse Zeman. “Please go to the BC Wildlife Federation website to make a donation and receive a tax credit receipt, get updates, or learn about volunteer opportunities for the project.” People can also donate directly to the Okanagan Nation Alliance
