I have been meaning to post this for some time. You will note that the “bug” was found in November.. partially frozen. Thanks to Tyson Ehlers for this information and the pictures.
I thought I’d share these photos of Lethocerus americanus (Giant Water Bug) that my 9 year old son Silas and his friends found in the wetlands adjacent to the river by our place in Vallican (site of the BCWF wetlands tour last summer). They found the bug partially frozen in ice in late November and it has since been living in a goldfish bowl. It is very active and feeds readily on minnows. I had no idea these existed in our area. The other common name is ‘Toe Biter’ as they can inflict a painful bite. They inject their prey with powerful enzymes like spiders and then feed on the partially digested insides.

A successful wetlands workshop was held at Hunter Siding Marsh on Bonanza Creek from June 7 to 9, 2013. Twenty-five people participated in the training that was provided by Neil Fletcher and his helpers from the BC Wildlife Federation (BCWF). Specialists in soils, wildlife, birds, insects, amphibians and bats were brought in to provide the training. A bio-blitz of Bonanza Marsh was performed at the same time by many of the same specialists. The results of the work on both marshes will be posted on this site as soon as they have been compiled by the BCWF.
A follow-up meeting was held in Winlaw on June 12, 2013 to consider further work to be done on the wetlands of the Slocan Watershed. This resulted in some creative thinking and the initiation of a collaborative group, the Slocan Wetlands Assessment & Mapping Project, SWAMP, to further the work started by the workshop.
SWAMP Vision: To see healthy, intact functioning wetlands and riparian areas providing home to diverse species and providing natural processes throughout the Slocan Valley.
Initial work will be to identify all of the wetlands in the watershed. Then prioritize them and begin the mapping and categorization process. Restoration projects will be identified throughout the process as well as identification of unique habitat or biodiversity wetlands that need special status.
As this group develops a communications network will be set up to keep everyone aware of the work that is involved. This website will be a link in that network. Stay tuned.
North American river otters (Lontra canadensis) are elusive mammals and little is known of their current population and ecology in most of interior British Columbia including the West Kootenays. Otters are a social species and the top predator within freshwater aquatic ecosystems. Our limited knowledge about their local ecology and the role otters play within these ecosystems is not well understood. Elsewhere in Eastern Canada and parts of the United States river otter presence is used as an indicator for water quality and ecosystem health.
Local research efforts are underway to discover more about their populations and ecology, and you can help!
Send us your otter stories, where you saw them and when. The most recent sightings are best.
Please send to firstname.lastname@example.org
The above post is from researcher Rhia Mackenzie. You can also send your stories in the comment section below and I will forward them to her. Because otters are a fur bearing animal all data and stories will be kept confidential and not be shown on this site. Rhia will only use the data for further research.
Eurasian Collared Doves have been identified in New Denver. This species, which has been in Nakusp for several years was only first recorded in this area when I saw one in Rosebery last year. I did not see it apart from a few days in the spring when it sat in the neighbour’s tree and called regularly. Since we had a nesting pair of Merlins in the same area it may have moved on or worse (for the dove). Thanks to Anne Champagne for reporting the sighting.
Eurasia Collared Doves are not native to this area and a considered “invasive”. Please report any further sightings to this website.
Further on bird sightings, I am happy to report that the Barn Swallows (a species of concern in this area) are back in Silverton. There are perhaps three or more pair flying around and hopefully nesting again. There were two pairs nesting in Silverton the last couple of years.
After attending the Columbia Mountain Institute presentations in Silverton, we went on a field trip with Jakob Dulisse to Summit Lake. Looked at the fencing and culvert structures and examined four male Western Toads. One of the toads examined had been “tagged” earlier with an electronically readable implant. I gathered “road-kill butterflies. Four Mourning Cloaks, one Green Comma and one Orea’s Comma. Caught, identified and released one beautiful male Spring Azure.
The snow is nearly gone and all the birds are arriving. Yesterday I saw the first butterfly of the year for me. Thanks to John Acorn for identifying it as Compton Tortoiseshell (Nymphalis vaualbum). He notes “the large white spots are good field marks”. She was skittish and drinking from a mud puddle.
Also checked out the mussel shells at the north end of Slocan Lake. They are definitely Anodonta and, Dick Callison and I believe they are A. oregonensis.
Back after a hiatus while focusing on the Slocan Lake Stewardship Society, Slocan Solutions Society, Healthy Community Society and Columbia Basin Watershed Network
A number of projects are underway at the center here.
Water Monitoring of Creeks:
Four creeks that feed into Slocan Lake are being monitored, Carpenter, Wilson, Bonanza and Silverton. Data has been collected from these creeks since 2010. Carpenter Creek has been sampled nearly every week (Thanks Lane and Margaret) since July 2010. Continuous (hourly) water temperature data has been collected from Wilson Creek for three years with samples of water caught, sometimes irregularly, since June 2010. Bonanza has been sampled even before May 2010 and Silverton has been sampled, but not continuously, since July 2010. The samples are tested for conductivity, turbidity and pH. I plan on publishing the data here and filing it with the Columbia Basin Watershed Network water quality initiative.
The BC Wildlife Federation Wetlands Education Program is planning to hold wetlands training in the Slocan Valley as follows;
Wednesday June 12. Working Group Session (to work towards wetland restoration/conservation prioritization in the Slocan Watershed – with guest speakers and topical discussions)
Friday June 14 & Saturday June 15. Map our Marshes Workshop & Bioblitz
More on this later. If you are interested please contact me via the comments section or by phone at 250-358-2590.
More later. Richard
