Second Latta bridge an example of recycling industrial materials

On October 29, 2023 the new Latta Bridge on Jasper Avenue between 90 and 91 Street opened. It is the third bridge in this location. David Gilliland Latta, blacksmith, one-time Royal North-West Mounted Police constable, gold rush hopeful, and City Alderman, built the first bridge, a crude wood-timber construction, in 1911.

Growing automobile ownership, heavier vehicles, and increased transit frequency wreaked havoc in the intervening years, and in 1929 traffic engineers condemned Latta’s old bridge. Yet a replacement never came, as the onset of the Great Depression prevented the City from pursuing such a financially onerous project. A proposed ravine-fill alternative was abandoned when old coal mines were discovered under the site.

By law, the City had the authorization to spend up to $100,000 a year for works related to unemployment relief if Council so directed. In November 1935 they did, proposing a new bridge as a $44,000 make-work project for Edmonton’s starving labourers, accessing federal and provincial funding available through tripartite work relief agreements. The bridge was constructed in 1936 and demolished in 2022.

The second Latta Bridge was an early example of recycling industrial materials thanks in part to its use of upcycled components. Steel members produced for, but unused in, a 1931 modification to the High Level Bridge were altered at a storage site and hauled to the new bridge by tractor, while old streetcar tracks, hoarded by a Depression-conscious municipal government, were used to reinforce all mats in pedestals. https://www.forgottenedmonton.com/blog/the-latta-ravine-bridge

Share your vision for northeast river valley park

On September 24, 2023, the City of Edmonton opened Northeast River Valley Park. Edmontonians can now access the park’s amenities, but a long-term plan is needed for the park.

A strategic plan for Northeast River Valley Park will establish a unique vision, guiding principles, and recommendations in many areas including naturalization, restoration, access, and programming for the park. The plan will also incorporate the park into the City’s broader Ribbon of Green strategy, River Valley Planning Modernization project, and other City policies.

The vision statement will reflect the goals and plans for the park’s future. Share your ideas for the Northeast River Valley Park vision until February 29 at https://engaged.edmonton.ca/northeastrivervalleypark

Davies valley line station across the road from Roper Pond natural area

In the heart of the Davies industrial area near 75 Street and Wagner Road, the sleek and modern-looking Davies station stands three stories tall. Davies is the only elevated station along the Valley Line, built to ensure trains do not have to stop and wait for freight trains, which have priority over all other modes of transport. https://transforming.edmonton.ca/davies-station-a-future-focused-design-in-the-industrial-heart-of-south-edmonton/

Across from Davies station, on the other side of 75 Street is Roper Pond, constructed in 2004 as a naturalized on-line stormwater treatment facility and built to mimic a riverine marsh ecosystem. This YEG hidden gem consists of a large open water area with an emergent vegetation fringe and surrounding upland deciduous forests along the southwest and southeast perimeter of the wetland.

Roper Pond is connected to riparian areas of Mill Creek that form a relatively continuous corridor southward. The diversity of habitats and the site’s location within the Mill Creek riparian corridor offer an excellent opportunity to view a multitude of waterfowl and other bird species, various mammal species, amphibians and insects. https://www.edmonton.ca/city_government/environmental_stewardship/roper-pond-constructed-wetland

Study finds outdoor cats hunt and scavenge 2,000 species globally

Marian writes “I agree that cats are predators and many birds, insects and reptiles have been killed because of the hunting nature of cats. Birds and other animals are always wary of being attacked by predators like cats, coyotes and other ravine dwellers.

Perhaps tracking the number of kills around artificial sites such as solar farms and wind generators might also lead to a compromise between our needs as humans and the ability of birds to fly without the dangers they do not understand. Nice to know that there is a system of tracking birds flying on route to and from territorial nesting places.”

Highlands Scenic Drive now part of Dawson and Kinnaird parks

Constructed between 1932 and 1937, Highlands Scenic Drive was in what is now Dawson and Kinnaird parks between 82 and 67 Street. It was initially envisioned as an extended Jasper Avenue, but it soon morphed into a gently inclined drive along the bank of the river, and across the mouth of Rat Creek and thence in a north-easterly direction leading up to Ada Boulevard near 71 Street.

Opponents included Gladys Reeves, who asked “if the real beauty of the bank is best not viewed better from the top road, rather than cutting a gash right through the centre of those lines of beauty and thereby destroying fully a third of the growth as in the new scenic drive. To us it is like trying to view a beautiful picture by standing in the middle of the canvas.”

As the years passed, worsening road conditions, an unstable bank, and shifting policy surrounding the North Saskatchewan River valley, with an increased focus on recreation and conservation, spelt its demise, and between 1975 and 1978, the City undertook a naturalization program.

Bolstered by a $40 million provincial contribution, the area around the drive’s right-of-way, including an ex-dump, were transformed into Dawson and Kinnaird parks. All that remains is a dirt walking trail along the road’s old path. https://www.forgottenedmonton.com/blog/the-highlands-scenic-drive

Motus tracks birds that fly within 15 km of tower

Beaverhill Bird Observatory (BBO) has a Motus Wildlife Tracking System (Motus) which began operation on its 80-foot tower in August 2021. Motus is an international collaborative research network that uses coordinated automated radio telemetry to facilitate research and education on the ecology and conservation of migratory animals.

An important set of records occurred when 25 different Bank Swallows visited in the second half of July. These birds had been tagged near St. Albert, Alberta; Fox Creek, BC; Whitehorse, Yukon; and Fairbanks, Alaska. The tagging projects seek to better understand the migration routes and migratory phenology of the species, which is listed as threatened under Canada’s Species at Risk Act.

The two projects tagged 178 swallows and 25 visited on their southward migration. Bank Swallows, like other swallows, are renowned for their flying prowess. This was exemplified by a trip undertaken by one bird from Fairbanks to BBO, 2326 km, in only four days. The bird averaged 27 km/h for four days straight.

When a bird with a nanotag flies within 15 km of the BBO tower, the tag's signal is picked up and its serial number is decoded. The record is then automatically sent to Birds Canada’s central computer where the information is made available on their website https://motus.org/

Study finds outdoor cats hunt and scavenge 2,000 species globally

A new study has found cats roaming free prey upon almost any animal, reptile, insect, and amphibian around the world, their hunting so prolific and so successful, the authors found, that it poses a legitimate threat to global biodiversity.

​​Almost half of the victims were birds, followed by reptiles and mammals. Researchers also found a surprising number of insects, including emperor dragonflies and endangered monarch butterflies. The paper said the cat is among the most successful and problematic invasive predators in the world, a claim that has been made about cats before.

The menu includes nearly 350 species that are threatened, vulnerable or endangered, including the little brown bat and green sea turtles. Cats proved especially lethal on islands that have evolved without as many natural predators.

Most victims were small, weighing less than five kilograms, but cats scavenged the carcasses of animals much larger than they could kill themselves, like camels. The paper said the cats also ate spoiled and wasted food people left outside. https://www.cbc.ca/news/science/cats-are-killer-in-case-you-weren-t-aware-1.7059683
