RMN 2020 Activites:
Following is a summary of our work and involvement in nature and environmental issues as reported at our Annual General Meeting January 2021:
 
Upper Columbia Basin Environmental Collaborative - representative/member: Emma.  The UCBEC is an independent committee made up of representatives from several environmental groups. Its objective is to ensure ecosystems are considered in operations and mitigations of all upper Columbia hydroelectric dams and in the Columbia River Treaty.  This is accomplished by providing knowledge, technical support, comments, and support of public involvement in Treaty discussions.
 
Rocky Mountain Trench Natural Resource Society - representative/member: Jo Ellen.  The Trench society is a non-profit made up of nine other East Kootenay environmental societies.  They oversee the restoration of grasslands through partnerships with government, industry, First Nations and other non-government agencies.  Restoration work last year was at the Old Kimberley Airport, Hidden Valley/Silver Springs, Hatchery Ridge, and Sheep Mountain.
 
Early Morning Birding - a regular Wednesday morning field trip dedicated to birdwatching.  The skill of the birders varies from beginner through expert level. This year (2020) some of the more interesting outings involved hiking into McGinty Lake, hiking along the bootleg hoodoos trail, and through the Moyie Lake narrows by canoe or kayak. Two most notable events this year were on March 18th, while near Jaffray, a golden eagle attacked a Canadian goose close by.  Then near Wasa we witnessed a juvenile cowbird being fed by a junco and later by another adoptive mother of a different species.  This activity is co-ordinated under and adheres to club’s new Covid19 guidelines.
 
Kootenay Community Bat Project - RMN co-ordinator: Scott.  We assist other groups and conduct counts of bats and build and maintain bat boxes.  Members assisted the Baynes Lake Community in setting up and conducting a bat count on 12 June 2020 where we counted a total of 472 bats.  Hopefully the RMN will have our own count location for 2021.

Elizabeth Lake Western Painted Turtle Nest Monitoring - RMN co-ordinator: Greg.  We monitor and maintain a turtle nesting area at Elizabeth Lake, Cranbrook under the auspices of the Fish and Wildlife Compensation Program.
 
2019 / 2020 nesting year - eggs laid early in the year may hatch before winter, eggs laid in the fall will overwinter and the hatchlings emerge the next spring
 
100                                  nests found
952                                  total number of eggs found
333                                  dead eggs
223                                  dead turtle hatchlings found in the nests
69                                    live turtle hatchlings in nests
124                                  hatchlings that must have emerged on their own
193                                  Total hatchlings
50%                                 predation rate of turtle nests
 
In April/May of 2020, while repairing minor problems with the turtle fence, it was discovered that there was a major problem at the north end of bed A. There was essentially a ‘skunk highway’ from a downed tree over the fence. Thanks to Helga and Andy for delimbing the tree and removing the branches. The fence was repaired, and a cross fence was added to prevent skunk movement onto the beds. All the other minor breaks in the fence were repaired and the fenceline was brushed, to assist future monitoring. 
 
In 2020, there were 94 nests laid. So far, we have had no predation of the nests. In fact, there were no signs of skunks at all on the beds throughout the summer after the fence was repaired.
 
The weeds have been getting worse and worse over the years and it has become physically impossible to maintain weeding by hand. This year, 2 beds (beds C and D) were rotatilled and raked in the narrow window between fledging and nesting (2nd week of May) and it was a success. Thanks also to the Rocky Mountain Naturalist Volunteers that came to help weed out the invasive weeds in and around the beds. The invasive weeds are also on the increase in this area and will require constant monitoring.

Bluebird Trails - RMN co-ordinator Marianne.  Nest boxes for cavity nesting birds are built, distributed, maintained and checked by many of our members.  We had 23 active routes this year with 22 providing data for the 2020 summary.  This involved about 30 dedicated volunteer monitors, most of them Rocky Mountain Naturalist members. The data is sent to the Southern Interior Bluebird Trail Society (SIBTS) to be included in their annual data collection.
 
There was an 89% occupancy rate in the total number of boxes.  Mountain and Western Bluebirds use a little over half the boxes followed by Tree Swallows.
 
This year the success rate of both Western and Mountain Bluebird from hatchlings to fledglings was lower by about 10% compared to 2019.  There were 485 Western Bluebird fledglings and 314 Mountain Bluebird fledglings.  Tree Swallow success was lower by about 15%.  One possibility for mortality, often at about one week to two weeks of age, was cool, wetter conditions in late June and early to mid July.  447 Tree Swallows fledged.  Interestingly, the only ‘other’ bird species reported nesting in the boxes were House Wrens.  They used 4 boxes and also had a lower success rate than usual with 14 fledging out of 21 hatchlings.
 
Christmas Bird Count - RMN co-ordinator: Dianne.  The #121 count, our 23rd officially, was conducted successfully in both Cranbrook and Kimberley following public heath regulations and recommendations.  Cranbrook was 26 Dec 2020 and Kimberley was 3 Jan 2021.  The weather was warm for both; roads were clear for Cranbrook but icy for Kimberley.
 
No new species were seen.  Cranbrook recorded 47 species which was an average number with the highlight being a "Woodpecker Grand Slam".  Kimberley recorded 51 species - a new record for number of species.  The number of individual birds counted was Cranbrook 3,424 - which is low, average 2640 - and Kimberley was very low: 1,284 - average 2,405.  Participation was about average with 19 field observers and 13 feeder watchers for Cranbrook and 15 field counters and 8 feeder watchers for Kimberley.

Skookumchuck Prairie Important Biodiversity Area - IBA Caretaker: Dianne.  All seemed well out on the prairie - no major habitat issues were noticed.  Long-billed Curlew and Lewis's Woodpecker were observed in their usual spots.  The annual field trips for Wings Over the Rockies did not happen due to public health measures.
 
Data from the 2018 and 2019 cavity nesting surveys for Lewis's Woodpecker and American Kestrel were submitted to the BC Species Inventory.  Lewis's Woodpecker nests were searched for on two days.  Major contributions to iNaturalist observations in Wasa Provincial Park were made by BC Parks consultants.
 
The RMN submitted a comment to Recreation Sites and Trails, Gov't of BC regarding a land use application made by the Kootenay Dirt Bike Association which would see them manage existing dirt bike / off road trails north of Ta Ta Creek and build a day use and camping area.  Most of the trails are within the IBA and some trails impact the western-most curlew nesting field and Wildlife Habitat Areas designated for antelope brush and bluebunch wheatgrass.  A decision on this land use has not been made at time of writing.
 
A crown land request for a log-sorting area within the IBA was not supported by the Regional District of East Kootenay; the RMN did not comment on this application.

East Kootenay Invasive Species Council - RMN representative: Frank.  The EKISC AGM Oct 7, 2020 - delayed from May 2020 due to Covid shutdown.  Inventories of invasive plants in the Upper Elk Valley and Wycliffe were started.
 
The 2020 Golden Shovel Award went to Pam Turyk of the Kootenay Livestock Assn. for her contribution to the board of directors over many years.  Dave Ralph of ISCBC was Keynote Speaker.  He talked about using herbicides in the Fall.
 
Elizabeth Lake Committee - RMN co-ordinator: Stewart.  Elizabeth Lake was the top birding hotspot in the East Kootenay with 167 species in 2020 according to eBird. In a year when Covid 19 affected all our lives, Elizabeth Lake proved to be a popular spot for birders including the EMB group, nature lovers, school groups at both the elementary and middle school level, people looking for a safe area to walk, as well as those who taking advantage of the picnic tables to enjoy a break. However, there was no Turtle Day for schools and the community in 2020 because of Covid, although Greg and Katrin continued to monitor the western painted turtle nesting areas on the W side of the lake.
 
Chris New, Director of Recreation and Culture with the City of Cranbrook, continued to liaise with the Elizabeth Lake group, consisting of Helga, Greg, George F. and Stewart, up until his retirement in December 2020. Prior to that Chris submitted a proposal for funding for an upgrade of outdoor amenities including the trail, which forms a loop between the Tourist Information and the Elizabeth Lake Lodge, as well as an upgrade of the parking area off Wattsville Road, which would include an outhouse. A wooden observation tower close to the concrete hide was also part of the proposal.
 
Thanks to those who volunteered their time to pull invasive weeds near the turtle nursery area.
 
Membership Committee - RMN co-ordinator: Hasi. Sue R., long time member of the Naturalists, managed our membership position for many years.  She collected the fees, made sure forms were complete and updated including waivers, as well as communicating with the Executive.  Sue then submitted this information to BC Nature, our umbrella organization, so that members receive the quarterly BC Nature Magazine.  Sue has now retired from this position.  Sue, thank you for the time and effort you spent keeping our membership records.
 
In 2020, the Rocky Mountain Naturalists had 85 memberships on our list – a combination of family and single. Many of those people have renewed their membership for 2021.  Thank you for your support.

This year we had 16 active routes with 20 + active volunteer monitors.
 
There are several long routes that I am splitting into smaller sections so that there is less of a time commitment and more people can become involved. Please let me know if you are interested in a route so that we could go out together several times to get you started. It is a very interesting, rewarding activity which involves a box check and clean-out in early April with the first monitoring beginning about the third week in May. It is necessary to go out every one and a half to two weeks until the beginning of August to monitor and record observations.
Please contact me if you are interested in learning more about this opportunity. Marianne Nahm (via Comments below)

Rocky Mountain Trench Natural Resources Society Report
January 2017 - Jo Ellen Floer
Two regular meetings and one field day meeting were held in 2017.
One of the main discussion topics at the November 18th meeting were the solar panel applications. The majority of the proposals are on lands already treated for ecosystem restoration through the Society. As the Trench society is made up of member organizations, each organization was encouraged to comment on the proposals rather than just submit input from the Society. Dianne Cooper submitted a report on behalf of the Naturalists.
The Society is pushing the RDEK to start enforcing the Weed Control Act on Private land. The RDEK is going to develop an enforcement policy matrix and provide information on approaches to enforcement. That has not been provided to the Trench Society yet but the RDEK has replied with “Please direct any inquiries or report properties of concern to Jamie Davies, Recreation and Control Services Supervisor. He can be reached at 250-489-2791 or by email at jdavies@rdek.bc.ca “. Consider this approach if you know of lands with weed concerns.
The Society also met with two representatives of the BC Wildfire Service (formerly BC Wildfire Management Branch) to discuss issues around prescribed burning and how to have more burns in the trench. They are aware that a ‘natural’ state is a more resilient state. While there is funding and the ability to carry out the initial treatments, the maintenance is not being done. The society has requested that the maintenance be written into the original prescriptions so treatment areas remain in a ‘natural’ state.

​RMN Christmas Bird Counts report - Dianne Cooper
The 117th annual Christmas Bird Counts were conducted successfully on 28 December for Cranbrook and 4 January for Kimberley.  Dianne assumed organizing and compiling from Greg and Sue Ross.  The Ross’ took over from Anni Coulter and Mildred White in 1991 (I believe), initiating the count as an official Audubon Christmas Bird Count. Thank you for enthusiastically doing such a great job for 25 years, promoting the count, encouraging people to participate, hosting the count up many times, and much more.
Field observers numbered 15 for each count – not the same people – with some coming from Fernie and Wardner.  Cranbrook had 10 feeder counters and Kimberley had 6.
Each count had enough people this year to divide into the usual 4 teams to cover each of the four usual quadrants of the 24 km-in-diameter circle. Cranbrook sectors are Town-New Lake, Mission Wycliffe, Gold Creek, and Lumberton-Moyie.  Kimberley’s sectors are Town, the Northwest-Meadowbrook, Wasa and Wycliffe.
Cranbrook got 42 species on count day which was average; and Kimberley got 43 species which was above average for Kimberley. The highlights for the Cranbrook count include the following: the first record on a CBC for Northern Shoveler – four had been at the sewage lagoon since at least the end of October.  The highest number of Mallards ever were counted – the City ban on feeding them at the Mall seems to have had the opposite effect on their population or at least made them more visible on count day.  This year saw a flip in the ratio of American Crow to Common Raven in Cranbrook – usually there are more Ravens than Crows, but the opposite was recorded this year.  It was disappointing to miss Pine Grosbeak and White-winged Crossbill on the count after last year’s higher numbers for them.
The highlights for the Kimberley count include the following:  everyone survived the -32 C starting temperature.  Eurasian Collared-Dove numbers are increasing slowly since their first appearance in the area around 6 years ago – 18 were recorded.  Bald Eagles, Pileated Woodpecker and House Finches were at an all-time high.  A good number of American Goldfinch were recorded.
Both counts got good numbers of chickadees, except Chestnut-backed, perhaps the lower temperatures make them more evident at feeders.
Count week species – seen three days before, or three days after count day – turned up some very nice species: Varied Thrush, Pygmy Nuthatch, and a Common Redpoll for Cranbrook.  Yes, it was an off-year for most of the “winter finch” species, except for House Finch.

Editor's note: Oopsy, I think we missed posting this last year.  Enjoy! (Dianne C.)

The BCFO held their 25th anniversary AGM here in Cranbrook at the Prestige Rocky Mountain Resort and those that attending are calling it "top notch" and the Rocky Mountain Naturalists had a hand in helping to make it so. We arranged the birding field trips for the two consecutive mornings, Ruth Goodwin led the Wycliffe Rambler, Daryl Caulder Elizabeth Lake, Alan Barnard Ha Ha Creek Valley, Dean Nicholson the Spray Irrigation, Three Ponds and Dianne Cooper led them to the Skookumchuck  Prairie  IBA.  

Over 80 delegates attended, there was a technical session about the BC Breeding Bird Atlas, the Annual General Meeting, a banquet with keynote speaker, Jared Hobs, who delivered an informative and passionate presentation about the plight of both Western Screech-Owls, and Spotted Owls in BC.

Mike McGrenere has assumed the role of BCFO President. Marian Porter and Monica Nugent are the new additions to the board. Congratulations to all that attended and helped the RMNats make this a special weekend for everyone! 

As southern B.C. labours under an ongoing drought, many kinds of tough, hardy plants are thriving. Fields of invasive weeds are in full bloom in many vacant industrial lots around Cranbrook, and the short window of opportunity for fighting them is just about past.

Frank Hastings, who has been working for a contractor hired by the City of Cranbrook and private businesses to eradicate weeds in targeted areas, recently conducted a tour for the botanically minded, to see land where the weeds have been allowed to thrive and others where they have been cleaned out.

Earlier that day, Hastings and two others spent two hours pulling weeds out along a 100-metre stretch of Mission Road. Eleven giant garbage bags of weeds were the result, which were taken to the dump later. “Eleven garbage bags in two hours by three guys,” Hastings said. “I challenge city crews to beat that!”

Many weed species are in full flower and going to seed: a who’s who of invasive flora, some species which has been growing in the area for decades, some only recently arrived.

And of all these unwelcome aliens, these colonizing visitors, knapweed is the king. 

Hastings explains that knapweed can suck water deep out of the ground with its taproot, so it can prosper in drought conditions. Each knapweed plant can produce 40,000 seeds per plant — “So with that number of seeds, it’s success rate doesn’t have to be very high.”

Knapweed also puts a chemical into the ground — catechin — which inhibits the germination of the seeds of other species. Knapweed is almost a super-species — a super-invasive species.

“Because it’s Eurasian in origin,” Hastings said, “It’s not considered food by wildlife or livestock.” He added that some local ranchers have been training their cattle to eat knapweed, introducing it into their diet so they get a taste for it.”

Right now, the best main window for controlling the invasives is past. By and large all the species are in flower, and whether humans like them or not, the bees love them. So herbicides can no longer be used without causing harm to bee populations.

Hastings says that the best combat is still the most labour intensive — pulling the weeds out by hand.

Mowing is another option, especially early on, which prevents the weeds from flowering and going to seed, and also starves the roots. Judicious application of herbicide during the two-month window of June and July is also effective. But pulling remains the best option.

The vacant property between Elizabeth Lake and the highway, where the water slides used to be, is a vast field of knapweed and other invasives including dalmation toadflax, curled dock, common tansy, burdock and mullein (which weed contractors generally leave alone, as its seeds provide food for birds). There are also tall clusters of sweet clover, which is not considered invasive and is generally left alone.

Hastings said because of the proximity of Elizabeth Lake and Jim Smith Creek, spraying is less of an option — no herbicide can be put down with 15 metres of a body of water. The best recourse, he says, is to have teams of weed pullers hit the field and pull up the weeds by hand. 

In this regard, Hastings said, a recent idea of the City of Cranbrook to train teams of summer students to pull weeds is a good idea. “What I’d start doing is mowing and bagging the flower stalks, then pulling and bagging stems and roots.”

Driving along Cobham Road to the industrial section of Cranbrook, Hastings points out how clean and weed-free the roadsides are. High traffic industrial areas are City priorities for weed eradication, and businesses like Fiorentino Contracting and Tundra Steel make the effort to clean weeds out of their properties.

But out along Industrial Road G on the way out of town is the field where the stock car race track used to be — another expanse of knapweed — both spotted knapweed (purple flowers) and diffuse knapweed (white flowers),  along with species like blueweed, sow thistle and goats beard, proliferate. Hastings shows a plant with short stems and yellow flowers — yellow gum weed. “It’s not listed as invasive yet,” he says, “but it’s been coming in fast.”

The big empty city-owned lot by Save-On Foods is mostly clean, except for the area used to dump snow in winter. A lot of the city’s gravel trucks used for hauling away snow will be carrying weed seeds from the summer, and that area is covered with tall, thick-stemmed weeds, baby’s breath and hedge bind weed. Hastings shows another relative newcomer — yellow tar weed. “It’s native to the Pacific Northwest, but it’s been making its way here.”

The big industrial lots covered with invasive weeds are one thing, but Hastings is interested in more awareness of the issue among residents. “Most people wouldn’t know an invasive weed if it hit them,” he said. 

Property owners could contribute by learing to identify different invasive species and how to eradicate them.

Article first published in the Cranbrook "Townsman", July 30, 2015

Following Lynn's alert last night (Sept. 17) about a strong smell like diesel coming from ditch below the storm drain outflow at the foot of 11th St. S. and corner of Innes Avenue, Cranbrook Fire Department responded quickly to my call and placed a boom at the storm drain outflow and about 200 metres downstream. This prompt action apparently has prevented any of the liquid entering Elizabeth Lake. This morning I understand that Deputy Chief Driver checked out this site again to ensure that the booms were doing their job.

When I visited the site around 10 AM today, Jim Melenka and Darren (?) from Environment Canada were already taking readings by the outflow, as well as the catchment basin at the foot of 11th. They had still to determine the possible source of the spill and were awaiting information from the City about the storm drain system in that area. Dave Humphrey was able to provide the enforcement officers with a sample taken from the ditch last night. Veron Novosad, the local Provincial Emergency Response Officer, was also in attendance, and had been at the site last night.

Birding at Elizabeth Lake the other day and was wondering how is Elizabeth Lake going to look when the water does go down and all of the floating islands are left along the north and and in front of the turtle nesting grounds?  This is a picture of the dipping dock.

The water levels have been rising at Elizabeth Lake.  Water from the lake goes through a culvert under Wattsville Road, into a creek which runs past the old waterslide site and the Heritage Motel.  Read the Townsman article in the Water at Elizabeth Lake link below.
