Thursday November 15, Presentation Night: The Pacific Marten on Haida Gwaii, 7 to 9 p.m. at The Exploration Place
The landscape and trophic ecology of Haida Gwaii have been altered in the last century by industrial logging and introduced black-tailed deer. Pacific marten are a native predator that is potentially benefitting from these changes and may be impacting species at risk. Presenter David Breault is an MSc candidate in Biology at UNBC. His research focuses on the habitat and diet ecology of Pacific marten on Haida Gwaii. David is looking at relationships between marten detections from remote wildlife cameras and habitat metrics collected using LiDAR, to better understand the habitat ecology of marten in this unique context. David is also using stable isotope analysis to estimate the diet of marten across seasons and in coastal areas. This event is presented in partnership with The Exploration Place. Everyone welcome.
Saturday November 17, Caribou Viewing Field Trip
The Club is holding a special field trip on November 17 to view a caribou herd located north of Prince George. Local experts Dale Seip and Doug Heard will be our guides to explain the province’s caribou recovery program for this region. The field trip is limited to 25 paid-up Club members who will carpool together in as few cars as possible. Interested Club members should email David Breault at email@example.com to let him know you wish to participate. Participants will be advised privately about what time and where to meet up for carpooling to the caribou site.
Wednesday Walkers, October 24
On our last walk of the season, it was a fine autumn day for a visit to the Western Larches (Larix occidentalis), with the trees caught mid-point in shedding their needles; some needles still bright on the trees, some making a golden carpet on the trail. (Darilyn’s photo) The view of the Nechako and the hills beyond was splendid. The feathery Clematis (Clematis occidentalis), in seed, would have been in bloom last May, with its sepals a lovely shade of blue. (Darilyn’s photo). The bog, where some cranberries were tucked in the sphagnum, was in its autumn colours. (Darilyn’s photo) Once again, we were lucky to see a Brown Creeper (Certhia familiaris) plying its way up a tree truck. To learn more about this all-season resident, check out the Cornell Lab of Ornithology at www.allaboutbirds.org.
I’d like to thank the many participants on our Wednesday Walks. Your enthusiasm is much appreciated. I’m grateful to Sandra E., Anne A., Darilyn, Miguel, Dave G. Nancy M., and Lorraine for the photographs they have contributed. I also appreciated the assistance of Anne A., Nancy K., Dyanne, Suzanne and Nancy M. in pre-hiking. A special thank you goes to Sandra K. who, amidst all our chatter, tends to the birding and birders. I am especially grateful for the support of Christine, Uta, Gillian, Dave and Sandra on our most recent walk, and for all who have offered constructive and supportive suggestions for the future conduct of our walks. If you have suggestions for a venue for a walk or would like to be involved in some pre-walking of trails please get in touch with me. The 2019 Wednesday Walkers will get underway April 10th. I’ll send a schedule in the late winter. Let me know if you would like to have your name removed from the email list. firstname.lastname@example.org
Other News and Events
Speaker is Dr. Michael Wulder, Canadian Forest Service. In forest environments wildfire and harvesting activities are the primary mechanisms for the removal of trees. Following these disturbances, the lifecycle of trees can resume naturally or via planting activities. The mapping of forest disturbances is increasingly common, with the quantification of the return of forests, or forest recovery, receiving less attention. In the same fashion that satellite data can be used to capture disturbances based upon temporal changes visible in the imagery, forest recovery can be monitored. However, given the punctual nature of forest removal and the longer time period required to observe the return of forests, different approaches are required. Here we show that analysis of time series satellite data can be used to relate forest recovery and that the spectral changes evident in the imagery can be corroborated using field plots, airborne laser data, or spatial patterns indicative of pre-disturbance conditions.
Following the colloquium, the NRES graduate students will presenting their posters in the Teaching and Learning Building Atrium.
This walk is a stroll in the Pidherny Hills to the larch grove over-looking the Nechako with, on our return, a quick stop at the bog, perhaps, to see some cranberries. I spotted the larch grove in all its golden glory from L.C. Gunn on the 17th. It will be fine if the needles stay on the trees until the 24th, but, if not, we’ll have an even finer view of the valley and river below and the hills beyond. We meet in the parking lot at the Spruceland Shopping Mall at the corner of 5th Avenue and Hwy 97 under the big Save On Foods sign at 9:20 a.m. There we sign a waiver form and arrange for carpooling. Departure time is 9:30 a.m. with return in the noon hour. Please dress for the weather, wear sturdy footwear, bring water and a snack. These slow walks to observe nature are open to members and non-members. If you accept a ride to the walk site, please chip in a Toonie for gas.

Thursday October 18, 7 to 9 p.m., Presentation on Amphibians in Central and Northern BC, The Exploration Place
Amphibians in central/northern British Columbia are uniquely adapted to seemingly inhospitable winter climates. These species are typically near the northern extent of their ranges, and likely migrated into the geographic region within the last 10,000 years. Cherie Mosher, a PhD Candidate at the University of Northern British Columbia (UNBC), will talk about known ways amphibians have migrated into central/northern BC, and how they survive the winters. In addition, Cherie will present her work on the coastal tailed frog (Ascaphus truei) of the Coastal Mountains. This ancient species has an unusual life history and, potentially, an even more unusual history and future in British Columbia. This event is brought to us in partnership with The Exploration Place. Everyone welcome (Bob Steventon photos).

Thursday September 20, Panel on Citizen Science
Three dozen attendees enjoyed a panel presentation and discussion about how people in Prince George, North America, and around the world actually participate in citizen science. The Prince George Public Library co-hosted the event, and set out displays of books of interest. Special thanks to David Breault, Jack Bowling and Heather Meier for the helpful information they shared and to Angie Joiner for pulling it all together. The citizen science hand-out provides links to many citizen science initiatives whether you are interested in birds, fish, bugs, and everything in between, and includes free smartphone apps. If you find more sites to add to the list, please email the information to the Club at firstname.lastname@example.org and we will add to the citizen science links soon to be located on the blog.
And here is an extensive article in the Globe and Mail on the contributions of citizen scientists to overall scientific knowledge of butterflies: https://tinyurl.com/y8b9esps as well as a link to UBC’s e-flora site where plant lovers can enter data and photos: http://ibis.geog.ubc.ca/biodiversity/eflora/
Wednesday Walkers, September 26, Cranbrook Greenway off Westcrest Drive (report by Dora Hunter)
We began our walk at the end of Westcrest Drive, where, in this summer of wildfires, a fire had been put out in its infancy, saving Prince George from the fate of some other communities in the province. On the Greenway, we found fungi to be few and far between, but, as Darilyn’s photo shows, we did find a small clump which served to demonstrate some of the many features a mycologist would note in the identification of a mushroom. Darilyn’s photo of the Orange Jelly captures the beauty of this specimen, which until recent rains was a crusty splotch on this conifer stump. Can you spot the Wood Frog (Rana sylvatica) in Miguel’s photo? It can withstand the cold temperatures of northern B.C. by converting liver glycogen to glucose and moving it into its cells, to serve as antifreeze. Any water is confined to body cavities and between cells where ice crystals do no harm. Another wonderful overwintering adaptation is that of the Black-capped Chickadee (Parus atricapillus), which on winter nights, as an energy conserving strategy, decreases its body temperature by about half. In our on-going quest to identify the mosses, Sandra demonstrated the defining points of Step Moss (Hylocomium splendens) (Photo: Miguel).
Sandra’s Checklist for the 26th
- Common Raven–stay for the winter.
- White-winged Crossbill — could stay for the winter; they go where the food
- is (cones), and it doesn’t matter what time of year it is.
- Golden-crowned Kinglet — a few will overwinter.
- Pine Siskin — usually leave, some milder winters we have some.
- Black-capped Chickadee — will overwinter.
- Pileated Woodpecker — will overwinter.
Wednesday Walkers, September 26, Cranbrook Hill Greenway off Westcrest Drive
We will access the Greenway from the end of Westcrest Drive on Cranbrook Hill. Last fall this area was a fairyland of fungi, and, with luck, recent rainy weather will ensure another bumper crop. We meet in the parking lot at the Spruceland Shopping Mall at the corner of 5th Avenue and Hwy 97 under the big Save On Foods sign at 9:20 a.m. There we sign a waiver form and arrange for carpooling. Departure time is 9:30 a.m., with return in the noon hour. Please dress for the weather, wear sturdy footwear, bring water and a snack. These slow walks to observe nature are open to members and non-members. If you accept a ride to the walk site, please chip in a Toonie for gas.
