When and Where did you see What?

Friday September 24, 2021 at 7:00 pm ZOOM intro to iNaturalist CST Central Standard Time (CST) is six hours behind Coordinated Universal Time (UTC).
The Friends of the Saskatoon Afforestation Areas will be presenting an " Introduction to iNaturalist" workshop virtually online. If you are interested in signing up for this virtual webinar use this eventbrite link https://www.inaturalist.org/journal/saskatoonafforestationareas/56080-when-and-where-did-you-see-what
This workshop builds on the iNaturalist presentation to Master Naturalists - entitled "When and Where did you See What?" by Sam Kieschnick iNaturalist curator and Urban Wildlife Biologist, "An intro to iNaturalist" by cassi saari a field biologist, ecological restoration practitioner and iNaturalist curator and Patrick McCrea a wildlife ecologist along with "A brief orientation to iNaturalist" by Carrie Seltzer, PhD in ecology staff member for the iNaturalist communication network. The workshop assists with getting involved with identifications on iNaturalist, taking observations to the next level and not to worry about being self conscious or anxious about your observations, and welcoming users. We would really like to impress the group with the community aspect of how iNaturalist comes together.
It is great fun to use iNaturalist, and get engaged with an amazing group of naturalists online, and meet some of them in-person! This is a great social network connection for anyone who enjoys and appreciates nature. iNaturalist is a great way to create field guides, and have a readily available calendar to refer to. As you wander and explore the great out of doors, often times you may have stopped to wonder what that was? The iNaturalist is a tool that can assist you to learn and answer this very question and discover the answer to "What is that, anyways?"

Red-berried Elder (Sambucus racemosa) / Cutleaf staghorn sumac (Rhus typhina 'Laciniata.')

There has been a mystery at the Richard St. Barbe Baker Afforestation Area in two different locations. There have been found two woody species that looked like they could be identified as Red-berried Elder (Sambucus racemosa) / Cutleaf staghorn sumac (Rhus typhina 'Laciniata') in 2020.

je9h mentions that for Red-Berried Elders "The laciniate leaf edges suggest either a planted or escaped horticultural selection. Both S. racemosa and S. nigra have such forms but S. racemosa has orange-brown pith in the branches and red mature fruits, while S. nigra has white pith and purple-black mature fruits."

Now then going back to the two sites in 2021, there seems to be only leaf shapes common to Sambucus racemosa and the cut leaf variety is not able to be found.

On looking at this particular observation, there does seem to be two leaf shapes for the same plant. https://www.inaturalist.org/observations/57871847

So, on doing some conversations with aaron881 on this page comparing their "cut-leaf / deeply lobed" variety - which was so very similar to my "cut-leaf / deeply lobed" observation - https://inaturalist.ca/observations/90828644 there was some interesting developments.

Looking online there is a scientific journal which states :"A variety with deeply dissected leaflets (var. laciniata) is noted in a number of local floras (e.g. Wolley-Dod 1937; Lousley 1976). The inheritance of the finely divided leaf character in Sambucus nigra was shown to be governed by a single recessive gene by Tobutt (1992). A similar genetic basis was found for the finely divided leaves of Sambucus canadensis (var. acutiloba) (Way 1965)."

But now the weird thing is....that even though I found my " laciniate / cut-leaf / deeply lobed" variety last year in the summer of 2020. I have really been searching and searching for it this year - the summer of 2021, and cannot find the " laciniate / cut-leaf / deeply lobed" specimen to make a follow-up observation of it this year, so maybe the leaf shape also has something to do with the environment from year to year if that is possible - and yet I thought there were additional elders in the two areas.

This website about ornamental elderberries -https://davesgarden.com/guides/articles/view/1061- also shows an elderberry "cut-leaf / deeply lobed" similar to the leaf which aaron881 and myself found in different locations.

Now then the question comes is for elderberries if there is ever a case where a sambucus plant has leaves which look one way in one year, and another appearance in another year--like where the leaves of the salsify which is a biennial will have different leaf shapes from year one to year two.

It also turns out that S. nigra -with black berries - is a larger sized, non-suckering shrub reaching 6 m, while S. canadensis is commonly suckering in habit, from https://davesgarden.com/guides/articles/view/1061 The hybrid ‘Sutherland Gold' seems to resemble the " laciniate / cut-leaf / deeply lobed" which were seen in the year 2020. Though, as I say, not any " laciniate / cut-leaf / deeply lobed"" to be found in either of the two locations in 2021.

THE HERB SOCIETY OF AMERICA’S ESSENTIAL GUIDE TO ELDERBERRY https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwjM5Y7TqdTyAhWmFlkFHQT0AAsQFnoECAIQAQ&url=https%3A%2F%2Fwww.herbsociety.org%2Ffile_download%2Finline%2Fa54e481a-e368-4414-af68-2e3d42bc0bec&usg=AOvVaw3ep7yrozUiZVx1j1hwyJ9Q
mentions that several cultivars of S. Niagra are available, and that there is an image of a leaf similar to the leaves in the observations shown in the Richard St. Barbe Baker Afforestation Area, and also the observation taken by aaron881. In the case of the afforestation area elderberry - the berries are red and not black as which S. Niagra would exhibit.

So, does anyone know if S. racemosa might have different leaf shapes for different years, and why the plant would have the typical standard leaf comparable to all other S.racemosa observations in 2021 and then some anomolous sightings with the " laciniate / cut-leaf / deeply lobed" variety of leaf appearing in 2020.

Afforestation area observations

The following appears to have two kinds of leaves on one plant.

and a few more S. racemosa observations not included here which were taken in the Richard St. Barbe Baker Afforestation Area.

Amur Maples - Acer ginnala, Acer tataricum ssp. ginnala

George Genereux Urban Regional Park has Amur Maples (Acer ginnala) This is the journal entry to explore more about their ecology, even though they were gorgeous this fall with their their red leaves. Not many red leaves in SK over the autumn months, so it was a real treat! It is not believed from archival documentation that these were afforested, but there are coming in from some random reason into this particular half of the smaller Saskatoon afforestation area.

Though Amur Maples are an invasive species in Eastern Saskatchewan , Chet Neufeld from the Native Plant Society of Saskatchewan - he mentions that - "From my experience with Amur Maple in Saskatchewan, it experiences a little more climatic stress than in the warmer, wetter growing zones in Ontario and the NE states. Because of this, I don't know of any sites in Saskatchewan where it has become invasive. That being said, climate change could very well improve conditions for it to the point where it becomes invasive. There might also currently be microsites in Saskatchewan where it could thrive to the point where it takes over a particular area. "

The website "Woody invasive species" mentions that the "Amur maple prefers sunny conditions, and is prone to invade open habitats like open woodlands, forest edges, prairies, and transport and utility rights of way. However, seedlings can germinate and grow to maturity in shade, and Amur maple is particularly well-adapted to exploit any canopy gaps that open up (Schuster and Reich 2018). It is most prevalent at disturbed sites."

That being said, there are at times areas in the forest where the planting pattern can be seen when the greenspace was afforested. Today while out and about, there were a few rows where it went Amur Maple, Green Ash, Amur Maple 3 times, Green Ash three times, so perhaps the Amur Maples were afforested. However, out of the entire remaining 474 remaining acres of the original 660 the only location where Amur Maples are sighted is on the north west quarter of George Genereux Urban Regional park

And very uniquely - as stated above abut forest edges and open woodlands, there are Amur maple seedlings which are coming in around the meadow edge, bordering where the internal meadow meets the outer irregularly shaped "ring" of woodlands on the west side of George Genereux Urban Regional Park.

We have these maples in SK. according to Saskatcheawn Conservation Data Centre
Acer ginnala
Acer negundo var. interius
Acer negundo var. violaceum
Acer saccharinum
Acer spicatum

@je9h mentions that "only Acer negundo and Acer spicatum are native to SK. The others have escaped from cultivation."

So, as we note that the afforestation areas are indeed laboratories in ecological succession, George Genereux Urban Regional Park provides an area to study the habitat and watch what happens with Amur Maples

Wild Roses of Saskatchewan How to tell them apart.

Links provided for photograph referencing the four SK wild rose species.

Minnesota Wild Flower has great images of blooms, leaves, fruit. Fruit images especially good for identification after late July

Glen Lee on Saskatchewan Wild Flower has images going into all the rose parts but not the fruit

Woods Rose Rosa woodsii
Wood' Rose https://www.saskwildflower.ca/nat_Rosa-woodsii.html
The only difference between Wood's Rose and Smooth Rose is the pair of prickles just below the wood's rose leaf nodes (infrastipular.) The stem shows broad flattened bases on every bristle. Mainly seen with 7 leaflets. 2-4 blooms at end of stem (can be more) Any shape fruit, mostly globular. Often mixed up with smooth rose.

Prickly Rose Rosa aciclaris
Saskatchewan Data conservation centre gives this as Rosa acicularis ssp. sayi
The tallest of all the prairie roses. 1.2 - 2.5 m (4 - 8 feet) high. Many many prickles on the stem. 5-7 leaflets rarely more. Only one to three flowers at the end of the stem, and usually one deep pink flower only. Most often the rose hip is long, oval and slender not globular. Round globular fruit.

Prairie Rose Rosa arkansas
Shortest of all prairie wild roses - low growing 15 to 46 cm high and may bloom after the other roses are finished. Whitish pink flowers. (6 to 18 inches) 9-11 shiny leaflets. 1-4 flowers on end of stem. Round globular fruit.

Note besides the three roses above, the Saskatchewan Conservation Data Centre SCDC also lists
Smooth Rose Rosa blanda
SCDC ranks Smooth rose as S1 Critically Imperiled/ Extremely rare At very high risk of extinction or extirpation due to extreme rarity, very steep declines, high threat level, or other factors.
Not listed on Sk Wildflowers so no link
Branches thornless or almost thornless as in images above.
Upper portions of bush and new growth has no bristles. Usually 7 leaflets. 1-4 blooms at end of stem. Round globular fruit. Often confused with Wood's Rose. The only difference between Wood's Rose and Smooth Rose is the pair of prickles just below the wood's rose leaf nodes (infrastipular.)

Because there are two rose species very similar, one could say that Wood's Rose/Smooth Rose are the most common species on the prairies.

Great to take pictures of the bristles, the numbers of leaflets on a leaf, if there are bristles below leaf nodes, and after the bush stops blooming an image of the fruit.

Campanula Those pretty blue bell flowers

There are two excellent discussions online by Mary Krieger

One in an observation acknowledging that here in Saskatchewan we may have Campanula Alaskana, but that there are other Campanula species to watch for also!
