City Nature challenge 1 week away...

Our CNC group will be at the small parking lot on South Drive in Birds Hill Provincial Park at 2pm on Saturday if anyone wants to drop by and say hello. It is on the north side of the drive just before South Drive turns northward towards the east end of the Pine Ridge trail - See you there :)

Sign up to the City Nature Challenge project nearest you to be updated on activities in your area

The snow has returned to give us one last chance at our winter activities but by mid week temperatures are predicted to be on the rise. Bird migration is definitely underway with eagles and other raptors as well as geese and a few other waterfowl leading the way. Horned larks join the snow buntings in the open fields and gravel roads. Near our southern border, some are already reporting seeing the hardiest of our returning warblers - the yellow rumped.

The City Nature Challenge is set for April 28 to May 1- four days to find wild things living near your in company with others all round the globe. If you join a project, your iNaturalist notifications will include the event journal posts. These often give you updates about event activities.

The Winnipeg Region project is here

If you will be somewhere else in Canada at the time of the challenge, check this list for a project near you...

If you will be somewhere outside of Canada, check the big list here...

Happy spring!

Tree Crickets - how to observe

listen in late summer for the long sustained trill (or maybe a metronome like chirp)
go towards the sound - when it is very loud ( or stops in response to your movement) start looking in the tops of the plants that are about a foot to two feet off the ground - if there are goldenrods, start with them
the insect is often in the open but is green and so blends in well
Have fun looking

Invitation to the Biodiversity Challenge - June 9 - 12, 2022

This challenge is timed later in the spring to provide an opportunity for areas in the more northerly latitudes to show more of their biodiversity. It is currently is a more free-from event - the only structure is that the dates of the challenge are the same across the various groups participating and there is a boundary of some sort.

Historically the event known as BiodiverCity was organized by Alberta Biodiversity Monitoring Institute on the NatureLynx platform and was primarily focused in Alberta. They are withdrawing from organizing the event but encouraging the spirit of the event to continue in whatever way the community feels suitable. I was approached along with others across the prairies to join in on the fun this year.

I have spun up two projects - as it happens I will be in two locations during the event period - so one for each location. (If anyone else would also like a project located where they are during the count period, I would be happy to make one for you - or help you make your own)

Here's the links to the projects ...

Happy observing!
Mary Krieger

Manitoba Botanists Big Year 2022 goes live

Inspired by the news story linked below, Diana Bizecki Robson challenged the Native Plants of Manitoba facebook group to do the 1,000 plant challenge.

Though iNaturalist is not mentioned by name in the article - I sure recognize all the people interviewed from their participation there - many of them have helped me out with confirming/correcting my identifications of plants observed here in Manitoba. The current Ontario big year project is here...

I have made a similar project for Manitoba. Join the project to have your plant kingdom observations added to the event. The event runs from Jan 1 to dec 31 so any observations you have previously made from earlier in the year will also count once you add them. We are now at 4 species. Ready, set, go!

white water crowfoot identification in Manitoba

Thread-leaved crowfoot Ranunculus trichophyllus

a geographical nomenclature split.... Plants of the Wold Online the taxonomic authority for iNaturalist reserves R. aquatilis for the other hemisphere

this is also the current situation in VASCAN Ranunculus trichophyllus Ranunculus aquatilis

Plants in Manitoba were formerly known under the name Ranunculus aquatilis var capillaceus or var diffusus - these are now considered synonyms of R. trichophyllus :)

the first group - Solidago Section Ptarmicoidei

Foolhardily sorting pieces into groups and having a go at the 'easy' ones

You will see my local observer bias in this page - this resource is oriented at someone who is learning the plants around them. They expect to encounter these plants again and again as they visit and revisit the places where they make observations. The first hurdle for this is to learn what is expected to be found based on past experience - yours and those who have come before - and then to be ready to recognize the exceptions - the unexpected.

In this way, observers are primed to document more thoroughly those individual plants that don't fit the expectations as well as being able to more efficiently document the commonly known things by showing in their images just what is needed to confirm the id.

Now back to the puzzle...

Section Ptarmicoidei

these are the plants that were once spun off into their own genus Oligoneuron and then got sucked back into Solidago. They all have their flower heads organized as corymbs which gives them a general wide at the top flattened profile

So the corollary is that flowerheads need to be present ( in bud, in flower, in seed) to separate these plants (until you become very familiar with your particular group of goldenrods and how they grow year round) and an image of the flowerhead from the side showing the corymb form should be included in the observation - if the flower is floppy or the wind is blowing, I have found you can stand close to the plant so the stem is braced against your pant leg and take the photo you need - if you have a better strategy, feel free to share below.

Remember it is possible to identify to Section without going all the way to species - so once you see that corymb on a solidago you can go ahead and id to that level - then in this section you only have 8 candidates to deal with in N. America ( and only 3 in our locality plus a hybrid - bonus!)

Here's the list... once you have the corymb documented, check that you have an image showing the distinct features (suggestions from other identifiers are welcome!) and either a description or a wide shot to give an idea of the habitat - your identifiers will be so relieved to stop muttering under their breath 'but where's the...'
