Anne Elliott's photos with the keyword: noxious

Always interesting to come across a white Creeping (formerly Canada) Thistle instead of the usual pink. Just as noxious as the pink ones. Back to the bio-blitz on Lisa Harbinson' property for my photos tonight. I have just added six extra photos. I really need to get the rest of my suitable shots taken that day edited and posted, so that I can send her the link to my album. The area we visited on 7 August was an 80-acre site near Bottrel, NW of Calgary. The site consisted of mostly open, low, hilly, ungrazed land, with a few Aspens and Spruce, and willows around three ponds (two of which were dry). On 25 May 2018, four people had visited this site for the first time - I had been unable to go, as I was spending the day with my daughter. The original visit was the result of the owners winning a free bioblitz at a Silent Auction, in connection with the Ghost Valley Community. A great idea and always a win-win situation, with the land owners learning a lot about what is found on their land, and the leader and participants enjoying a much-appreciated visit to a different location. We were very lucky to see an adult male Yellow-bellied Sapsucker with two juveniles. I rarely see one of these birds, but love to see the neat rows of small holes that they make on a tree trunk. Did you know that photographing mushrooms can be dangerous? I believe I knew this already and I was reminded of this on this bio-blitz. Towards the end of our hike, I stopped to photograph a not particularly photogenic mushroom that was growing on a very slight incline. I took one step back to focus better and lost my balance - not sure if my foot went down into a shallow hole or if I was tripped up by one of the many very small, short tree stumps. Whatever the cause, I did a most inelegant, slow-motion fall backwards, hitting my head hard on the ground, surrounded by my friends. Because I was wearing a backpack, I think this resulted in some whiplash, with my head falling back. It was not pleasant to drive anywhere the next day, especially each time I had to start off when traffic lights turned green. The muscles all around my neck and my shoulders are painful, but hopefully it will clear up before too long.

Definitely past its prime, but I love these Nodding Thistles at any stage, but especially when the pinky purple flower has died and the beautiful pattern of the spiny bracts can be seen more clearly. Flower head is 4-6 cm in diameter. The large Nodding or Musk Thistle is my favourite species of Thistle. Unfortunately, this quite spectacular and beautiful species is on the list of Restricted, Noxious, and Nuisance Weeds In Alberta. Its name, Nodding Thistle, comes from the fact that the flower heads commonly droop to a 90° to 120° angle from the stem when mature. It is a biennial that spreads rapidly by seed forming extremely dense stands, though when I have seen this species growing in several places within the city, there are usually only a few of them. It looks like i may have captured two insects as well - a teeny red mite on the left of the stem, and something else in the centre of the stem. I don't know if the latter is a moth or a beetle. www.botanicalgarden.ubc.ca/potd/2011/08/carduus-nutans.php en.wikipedia.org/wiki/Carduus_nutans This photo was taken at the Erlton/Roxboro Natural Area, not far from downtown Calgary, yesterday afternoon, 24 July 2018. It is the richest botanical area, for its size, within the city. Over 385 species have been recorded in an area of about three hectares. (All of Fish Creek Provincial Park has only about 460 species). Eighty species, however, are aliens, now occupying 90+% of the Erlton/Roxboro Natural Area. It is such a shame to see how the area is being devastated by plants that include Baby's Breath, Creeping Thistle, Yellow Clematis and other invasive species. The weather forecast for yesterday afternoon called for a risk of a thunderstorm. The sky was dark and gloomy, but we were very lucky that the rain stayed away. Our temperature at 9:00 this morning, 25 July 2018, is only 12C, which feels really good. This afternoon, it is supposed to get up to 23C.

All three photos posted this morning were taken yesterday, 27 July 2017. I decided to get up early and do a repeat botany walk at the Erlton/Roxboro Natural Area, not far from downtown. One of the reasons I did this, was that I really dislike doing this drive, especially knowing that I could so easily end up in the downtown area - which I avoid at all cost. So, a bit like getting back on a horse if one is thrown off, I hoped a second drive might make me feel more comfortable. Also, I really wanted to hopefully see a Wild European Rabbit or two, and sure enough, they didn't disappoint. Black and white, plain black, light brown, mid-brown. A few more photos of the Nodding/Musk Thistles were also on my mind. The Erlton/Roxboro Natural Area, not far from downtown Calgary, is the richest botanical area, for its size, within the city. Over 385 species have been recorded in an area of about three hectares. (All of Fish Creek Provincial Park has only about 460 species).

It is such a shame to see how the area is being devastated by plants that include Baby's Breath, Creeping Thistle, Nodding Thistle, Yellow Clematis and other invasive species. Common Tansy, seen in this photo, is one of the weeds growing at this location. In Alberta, its rating is Noxious. A shame, really, as its bright yellow, button-like flowers are quite attractive. "Common tansy is a perennial forb that reproduces by both seed and short rhizomes (underground horizontal roots). Introduced from Europe in the 1600’s, its pungently aromatic foliage has been used medicinally, as an insect repellant, and for embalming. Common tansy forms dense stands and the plants contain alkaloids that are toxic to both humans and livestock if consumed in large quantities. Cases of livestock poisoning are rare, though, because tansy is unpalatable to grazing animals." www.abinvasives.ca/factsheets/140513-fs-commontansy.pdf We are still under a Heat Warning. This morning, I happened to check the forecast for the coming week and, so far, the temperatures for next Thursday and Friday are 35C and 34C. The average high for the month of July is 22.9C. There are fire bans in many places in Alberta, as everywhere is bone dry.

The large Nodding or Musk Thistle is my favourite species of Thistle. Unfortunately, this quite spectacular and beautiful species is on the list of Restricted, Noxious, and Nuisance Weeds In Alberta. It is a biennial that spreads rapidly by seed forming extremely dense stands, though when I have seen this species growing in several places within the city, there are usually only a few of them. Yesterday, though, I saw how, if left, these Thistles can spread. I finally got out on a botany walk yesterday afternoon, 25 July 2017. The smoke from the British Columbia and Alberta wildfires has cleared, it was a lovely sunny day, and at last the destination was a place to which I could drive. Also, I knew that this would not be a very long walk and it was all on the level. I was hoping that there would at least be a few of these thistles growing. Most of the flowers had died, but I still love those spine-tipped, inner and outer bracts. The flower itself is a beautiful pink/purple. I have added a previously posted photo showing a flower in its prime, in a comment box below. www.botanicalgarden.ubc.ca/potd/2011/08/carduus-nutans.php en.wikipedia.org/wiki/Carduus_nutans This photo was taken at the Erlton/Roxboro Natural Area, not far from downtown Calgary.

This is the first photo I've posted from 31 August 2016, when I paid a quick visit to a couple of places in Fish Creek Park. I don't remember too much about it, except that I had picked up my new car just two days earlier and I was concentrating really hard on driving it : ) My first stop was at Burnsmead, as I wanted to check yet again to see if there were any mushrooms - a few years ago, I had photographed several amazing ones, including Stinkhorns and Bird's nest fungi. Since then, I haven't really seen any mushrooms there. A quick walk around the storm-water ponds found me this Katydid (?) on a Common Tansy plant. I think I have only ever once seen a Katydid and, now that I think about it, that, too, had been found at Burnsmead. Though Common Tansy (Tanacetum vulgare) is a noxious weed that grows in our natural areas, I still like coming across it, with its beautiful bright yellow, button-like flowers. "Introduced from Europe in the 1600’s, its pungently aromatic foliage has been used medicinally, as an insect repellant, and for embalming. Common tansy forms dense stands and the plants contain alkaloids that are toxic to both humans and livestock if consumed in large quantities. Cases of livestock poisoning are rare, though, because tansy is unpalatable to grazing animals. Because of its long medicinal and horticultural use, Common tansy is still available in plant nurseries and from herbal remedy suppliers. Gardeners should not purchase Common tansy." "The family Tettigoniidae, known in American English as katydids and in British English as bush-crickets, contains more than 6,400 species. It is part of the suborder Ensifera and the only family in the superfamily Tettigonoidea. They are also known as long-horned grasshoppers, although they are more closely related to crickets than to grasshoppers. Tettigoniids may be distinguished from grasshoppers by the length of their antennae, which may exceed their own body length, while in grasshoppers are always relatively short. The name "katydid" comes from the sound produced by species of the North American genus Pterophylla (literally "winged leaf"). The males of katydids have sound-producing organs (via stridulation) located on the hind angles of their front wings, which in some species produce a sound thought to resemble the words "Katy did, Katy didn't", hence the name. In some species females are also capable of stridulation. There are about 255 species in North America, but the majority of species live in the tropical regions of the world. The diet of tettigoniids includes leaves, flowers, bark, and seeds, but many species are exclusively predatory, feeding on other insects, snails or even small vertebrates such as snakes and lizards. Some are also considered pests by commercial crop growers and are sprayed to limit growth." From Wikipedia. Birds seen included a Double-crested Cormorant, Coots, Mallrds, a Clay-coloured Sparrow, and a Pied-billed Grebe. A short while later, I called in at Sikome for a few minutes, just long enough to photograph a row of about eight Mallards resting on a log in the creek. Felt kind of sorry for the males who were in eclipse mode, so had brown heads instead of their gorgeous, iridescent green/purple.

The large Nodding or Musk Thistle is my favourite species of Thistle. When I saw this one, it was the only flower that was not well past its prime. Unfortunately, this quite spectacular and beautiful species is on the list of Restricted, Noxious, and Nuisance Weeds In Alberta. It is a biennial that spreads rapidly by seed forming extremely dense stands, though when I have seen this species growing in several places within the city, there are usually only a few of them. However, if they are left .... en.wikipedia.org/wiki/Carduus_nutans This photo was taken on 8 October 2015. Friend Sandy had asked if I wanted to go with her to join friends down at the Irrigation Canal in the city, for a birding walk. This was a long walk - three and a half hours - along both sides of the canal. It was a beautiful fall day with a lovely blue sky. Also, enough trees were still dressed in gold to give some colourful reflections in parts f the canal. The water level was very low, creating just a narrow strip of water with a wide mud bank on either side, that had attracted a number of Greater Yellowlegs and a single American Golden-plover juvenile. The latter was a new bird for me and, though I could only get a very distant, poor shot, I did post it on Flickr. To me, a juvenile American Golden Plover looks so similar to a juvenile Black-bellied Plover (from photos I've seen), but the ID for the bird we saw was given as American Golden-plover. Much of the time, there were pale, dead grasses in the background and this bird was almost invisible. Great camouflage. We also saw several Hooded Mergansers there. I don't often see Hooded Mergansers and, when I do see one, it's always a long way away. They are quite spectacular ducks, especially the males, who have a crest at the back of their head and can raise this black and white "hood" or lower it.

Overslept by an hour and a half, so gotta post and run and see if there is any way to find the group of people I'm supposed to meet up with this morning!

I always think this is rather a strange flower, but with such a beautiful pattern on the petals. Photographed this noxious weed on 23 June 2015, when I was on a botany walk at Griffith Woods. "An annual or biennial (forming a rosette the first year) plant that reproduces by seed only. Black Henbane was introduced from the Mediterranean and has been used as a medicinal plant since the Middle Ages, and was also used in ancient religious rites because of its hallucinogenic properties. It was even used as a flavoring in beer until the Bavarian Purity Law of 1516. All parts of the plant are poisonous to humans and animals when ingested – tissues contain several toxic alkaloids. Symptoms of poisoning include impaired vision, convulsions, coma, and death from heart or respiratory failure. It is a member of the nightshade family and also called ‘stinking nightshade’. A single plant can produce as much as half a million seeds in one season, which are viable for about 4 years." www.invasiveplants.ab.ca/Downloads/FS-BlackHenbane.pdf -

On 16 August 2015, I went with a group of friends to Carburn Park to look for Warblers and several species were seen by at least some of the group. Group size was much too large even after splitting in half, but I think everyone was so thankful that it wasn't raining, unlike the previous day of heavy rain, that they came out to enjoy the sunshine. I enjoyed seeing a Merlin, a number of Double-crested Cormorants, and several Pelicans that flew overhead. Without binoculars, I didn't really see any of the Warblers, except for a quick glimpse of one Yellow-rumped Warbler. As you can see from this photo, my eyes were not always looking upwards : ) On any birding walk, I'm always looking around me to see what else there is to photograph. We tend to walk on such uneven ground, that my eyes are mostly downwards anyway, making sure I don't catch my foot in a hole or go flying over a fallen branch or log. This Common Tansy plant was growing along the edge of the path. Though Common Tansy (Tanacetum vulgare) is a noxious weed that grows in our natural areas, I still like coming across it, with its beautiful bright yellow, button-like flowers. "Introduced from Europe in the 1600’s, its pungently aromatic foliage has been used medicinally, as an insect repellant, and for embalming.

Some of you will be familiar with this rather beautiful flower and its silvery seedheads. Unfortunately, despite its beauty, it is an invasive species and widespread. This is one of three species of Clematis that occur in the wild in Alberta, the other two being the native Western Clematis and the Purple Clematis/Blue Clematis. This yellow species was introduced from Japan as an ornamental garden plant, but has now spread to natural areas where it chokes out and kills native plants, shrubs and trees. Taken on 7 August 2015. On 7 August 2015, four of us were extremely fortunate to have the chance to visit the home and highly varied topographic 62-acre property belonging to Frances and David Dover. We felt honoured and privileged to meet and spend time with Frances and David, and also their daughter Carolyn and her husband Clair. A delightful family who welcomed us so warmly into their home and land. This acreage of grassland, forest, rolling hills - and special gardens - is not far from Millarville, SW of Calgary. In fact, it's in an area that I often drive through when I only have time for, or only feel like doing, a short drive. Amazing what little gems exist out there. This is not just a beautiful property, but is very special for various reasons. For one thing, read any history of Alberta and you will find the Dover family, including David's mother, Mary Dover. Second, among the trees and open "lawns", there are Peony flower beds, containing 100-150 heritage Peonies, each one different, that have now multiplied to more than 300 plants. Unfortunately, they bloomed a couple of weeks early this year, and all the flowers had gone to seed. Another open area had a different kind of ground cover - Thyme, which smelled wonderful. If I remember correctly, this was the open space where the Calgary Philharmonic Orchestra performed on one occasion! There are two large ponds on the property and another smaller area of water that they hope to turn into a Japanese Garden. There is a total of seven wetland basins, including these. It was while walking around the Japanese Garden that a large brown 'shape' could just be seen through the dense trees - a handsome Moose buck. I will look properly at the four or so photos I just managed to get and will slip one of them into my photostream sometime soon, just for the record, definitely not for the photo quality : ) This was also where a Great Horned Owl was seen flying through the trees by some of us (not me, ha!). There are grassy paths winding through the acreage, up and down hill, that take David seven hours to mow. They are not pristine, velvety paths, but instead, they seem to take nothing away from the wildness of the whole area. One of the animals that have passed through is the Cougar. In fact, several years ago, I saw a video taken on a nearby (or adjacent?) property, where a 'kill' and night-time camera had been set up and a total of six different Cougar individuals were seen! Even the Dover's home is unique and beautiful. It is completely built of concrete (and glass) - floors, walls, ceilings, roof, deck, and so on. A Hummingbird feeder and regular bird feeders, set up on the patio, attract a variety of birds. We sat on the patio after our walk to eat our packed lunches - and to enjoy a delicious Orange Pound Cake that Frances had made for us, along with refreshing Iced Tea - thank you so much for this, Frances! While I was waiting for one of three tiny Calliope (?) Hummingbirds to come back, I was lucky enough to see a little Mountain Chickadee, along with many Pine Siskins. We could also hear a Red-tailed Hawk in the area. Saw a total of 22 bird species. There is just so much I could write about this visit and family. Instead, or for now, I will add several links to more information on the Internet. This was a memorable day for us. Thank you so much, Frances and David, Carolyn and Clair, for being so kind and welcoming us into your home and gardens. books.google.ca/books?id=Tr36Tq_gadcC&pg=PA290&lp... www.westernwheel.com/article/20110727/WHE06/307279983/-1/... David's mother, Mary Dover (her father was A. E. Cross), was "a dynamic and distinguished Calgarian, particularly known for her work with the military during World War II." As well as being an army officer, and an alderman, she was also a preservationist.

Though Common Tansy (Tanacetum vulgare) is a weed that grows in our parks and natural areas, I still like coming across it, with its beautiful bright yellow, button-like flowers. This particular plant was photographed at Lafarge Meadows, Fish Creek Provincial Park, on 14 September 2014. In Alberta, this plant is listed as Noxious. It was a beautiful, sunny day - hard to believe that we had had two heavy, late-summer snowfalls on 9 and 10 September. "Introduced from Europe in the 1600’s, its pungently aromatic foliage has been used medicinally, as an insect repellant, and for embalming. Common tansy forms dense stands and the plants contain alkaloids that are toxic to both humans and livestock if consumed in large quantities.

I always think that Black Henbane is a strange flower, but with such a beautiful pattern on the petals. Photographed the seedpods of this noxious weed in Carburn Park yesterday, 17 August 2014. I love the seedpods this plant produces! "An annual or biennial (forming a rosette the first year) plant that reproduces by seed only. Black Henbane was introduced from the Mediterranean and has been used as a medicinal plant since the Middle Ages, and was also used in ancient religious rites because of its hallucinogenic properties.

After a volunteer shift on 23 July 2014, I wasn't too far away from the Erlton/Roxboro Natural Area, where I was finally going to go on a botany walk. Having been to this location several times before, I knew it was a short, easy, flat trail, and that I could go as far as I wanted and then turn back early, which is what I did. I've missed pretty well all the botany and birding walks the last few months, which is quite depressing. The main thing I wanted to see were these Nodding / Musk Thistles, as they are my favourite species of Thistle. They are called a "weed", but I love to see them. The sun was unfortunately in the wrong direction, so I was only able to get a couple of OK shots, but better than nothing. Its name, Nodding Thistle, comes from the fact that the flower heads commonly droop to a 90° to 120° angle from the stem when mature. Here in Alberta, this species is a noxious weed - but a beautiful one. With a couple of hours to "kill", I had spent them at the Reader Rock Garden, which was just a few minutes' drive away from the evening botany walk location. en.wikipedia.org/wiki/Carduus_nutans

I had to edit this photo to pass on to local botany friends, so thought I'd also add it to my Plants of Alberta album. The female flowers have a much shorter, rounder calyx than the male, and I'll post a photo of one later. This species is native to most of Europe, Western Asia and Northern Africa, so is a non-native plant in Alberta, where it is a noxious weed. Taken at the Erlton/Roxboro Natural Area on 23 July 2014. www.agric.gov.ab.ca/app107/loadPest?action=display&id=61 This morning, I slept through my alarm's loud music for an hour and then for an extra hour and a half. Have an Open House to go to this afternoon, so am in a real rush and may have to finish off today's photos when I get home.

Some of you will be familiar with this rather beautiful flower and its silvery seedheads. Unfortunately, despite its beauty, it is an invasive species and widespread.

This yellow species was introduced from Japan as an ornamental garden plant, but has now spread to natural areas where it chokes out and kills native plants, shrubs and trees. This particular flower was photographed at the Reader Rock Garden on 25 June 2014 - always surprises me that they haven't pulled this plant, though it doesn't appear to have spread at this location. Today, 1 July 2014, is Canada Day. We live in such a great and free country, which is something to be remembered and thankful for, each and every day! A special wish and thank-you for all those Canadians who are serving our country, especially overseas! This is Canada's 147th birthday - we are so young! "Canada Day (French: Fête du Canada) is the national day of Canada, a federal statutory holiday celebrating the anniversary of the July 1, 1867, enactment of the British North America Act, 1867 (today called the Constitution Act, 1867), which united three colonies into a single country called Canada within the British Empire. Originally called Dominion Day (French: Le Jour de la Confédération), the holiday was renamed in 1982, the year the Canada Act was passed. Canada Day observances take place throughout Canada as well as among Canadians internationally." From Wikipedia.

Taken at Erlton/Roxboro Natural Area on 27 July 2011. The Erlton/Roxboro Natural Area is located on the east side of the Elbow River above the southwest community of Roxboro. It was completed in 1996. This is one of the richest areas in Calgary for wildlowers, but unfortunately, many non-native plants and shrubs have taken over much of the area - such as Caragana, Goat's-beard, Baby's Breath and Yellow Clematis.

The large Nodding or Musk Thistle is my favourite Thistle species, so I was kind of happy to notice this one when I was down in the Grand Tetons, Wyoming, US, on 15 September 2012. Though a little past its prime, I still love the arrangement of those spiky bracts. Here in Alberta, this Thistle is an invasive "weed", but I don't know how it's classified in the US.
