Erlton/Roxboro Natural Area

Happy Easter to everyone who celebrates! Hope you have sunny days the next few days, so that it feels like spring. When I checked our weather forecast very late last night, it was for snow today, so I changed my plans for a day out. Woke up really late this morning and the sun was shining. I guess snow could still arrive this afternoon. This little rabbit is one of the Wild European Rabbits that I've seen in Calgary. I'm not sure if they are only found in this one area of the city or elsewhere. Seen on 23 July 2014, when I went on a botany walk at the Erlton/Roxboro Natural Area. Right next to this natural area is a Cemetery - funny, I do tend to see Rabbits in cemeteries, either these Wild European Rabbits, which come in all sorts of colours (light brown, black, black and white, and so on), or the White-tailed Jackrabbits. The town of Canmore, near Banff, in Banff National Park, has had a problem with these Wild European Rabbits. They attract Coyotes and other wildlife into the town. They were going to do something about this problem, but I don't know if they ever managed to "get rid" of them all. I seem to remember reading that a fair number of them were sent to British Columbia to a sanctuary there and the rest were "got rid of". Here is a link to a Calgary Herald newspaper article from 15th December 2010, about the problem with these Rabbits in the town of Canmore, near Banff: They were, of course, also eating the plants in people's gardens, which some home owners complained about. "Canmore Mayor Ron Casey is taking aim at the picturesque Alberta town's rascally rabbits. Casey, who said the animals are attracting predators such as cougars, has secured support for a $50,000 budget to deal with feral rabbits."

Almost called this "Oh what a tangled web we weave" (quote by Sir Walter Scott). Cat's cradle is a string game you may remember from childhood. It requires two people to pass the string back and forth to make various string shapes. Cat's Cradle instructions can be found at the following two links: youtu.be/CAZhx5PKgl4 www.wikihow.com/Play-The-Cat's-Cradle-Game 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 had missed pretty well all the botany and birding walks the previous few months, which was 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. This flower head, past its prime, had quite a fancy tangle of spider web over it. 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. en.wikipedia.org/wiki/Carduus_nutans 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.

Some of you will be familiar with this rather beautiful, larger than a Dandelion, seedhead. Unfortunately, despite its beauty, it is a highly invasive species and widespread. This one, along with many others, was growing at the Erlton/Roxboro Natural Area in Calgary, on 27 July 2011. The background is of another invasive weed, Baby's Breath. It is quite likely that someone threw an old pot of these tiny, white flowers over the fence from the cemetery next door, and they have spread and keep spreading. en.wikipedia.org/wiki/Tragopogon_dubius The Erlton/Roxboro Natural Area is located on the east side of the Elbow River above the southwest community of Roxborough. 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 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. 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 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.

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.

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.

My heart goes out to all those who have been affected by the devastating tragedy in the province to our east, after a collision on Friday (6 April 2018) between a Saskatchewan junior hockey team’s bus and a tractor-trailer in rural Saskatchewan. That afternoon, the Broncos junior hockey team of Humboldt, Saskatchewan, were en route to a playoff game in Nipawin. Twenty-nine people were on board the team bus. Fifteen people were killed, including the coach, assistant coach, bus driver and a team announcer. Others remain in hospital. The tractor-trailer driver survived. There has been such a huge outpouring from people across Canada, and beyond. Such sadness, especially at so many young lives lost. ------------------------------------------------------------------------------------------------ There are a number of Wild European Rabbits in Calgary, and this is just one of them. It always feels strange to see what look like pet rabbits wandering loose in people's gardens and around a neighbourhood. This one was seen on 23 July 2014, when I went on a botany walk at the Erlton/Roxboro Natural Area. It was busy eating the grass by this tombstone and then it took a good look at me before continuing to feed. Right next to this area is a Cemetery - funny, I do tend to see rabbits in cemeteries, either these Wild European Rabbits, which come in all sorts of colours, or the White-tailed Jackrabbits.

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. 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.
