The Recovery of Trumpeter Swans in Alberta
BY NICK CARTER
Historically, trumpeter swans were found throughout Alberta. But by the early 1900s, the species was near extinction, mainly because of overhunting. Through concerted conservation efforts, the population is now well on its way to recovery – an amazing conservation success story.

Citizen Scientists Come to the Aid of the Tenacious Franklin’s Ground Squirrel
BY GILLIAN CHOW-FRASER AND RICHARD SCHNEIDER
In Alberta, the status of Franklin’s ground squirrel has still not been determined. The provincial government maintains that there is not enough information to say whether the population is stable or imperiled. In the spring of 2022, Nature Alberta initiated a citizen science project to help fill some of the data gaps. The results are presented here.

Diminished Chorus: The Decline of Grassland Birds
BY NANCY MAHONY
Few people are lucky enough to experience the dawn chorus on Alberta’s native grasslands — a bewildering concert of ringing trills, melodious gurgles, and jumbled songs. I’ve had the good fortune to do so on many May and June mornings, as a biologist researching grassland songbirds at one of Canada’s largest remaining native prairies, the Suffield National Wildlife Area near Medicine Hat.

Wild Boars on the March
Initially, wild boar numbers were low and they went largely unnoticed. However, their high reproductive rate is a recipe for exponential growth, which is exactly what has happened.

Seeing Red Over Red Tape Reduction
BY LORNE FITCH
Founded in political ideology, the provincial government’s current red tape reduction efforts have created a boondoggle of confusion, weakened protections, and, ironically, more red tape. The red tape being “reduced” hobbles land-use protection on public land, the land held in trust for Albertans.

The Implications of Shifting Baselines on Nature Conservation
BY LU CARBYN
Ecosystems change over time without any tampering by humankind. Human impacts, however, have caused massive changes over a short period of time that have resulted in serious environmental concerns, including loss of biodiversity.1 We are all aware of the global issues of habitat loss and wildlife extinction around the world, which call for intervention and leadership from governments, academics, and researchers. However, we do not need to look so far as the destruction of tropical forests of Brazil or Borneo; we can see these issues right here in Alberta.

Death by “Data Deficient”: The Disappearance of Wolverines in Alberta’s Eastern Slopes
BY GILLIAN CHOW-FRASER
Olaus Murie once wrote, “I wonder if there is another inhabitant of northern wilderness that so excites the imagination.”1 The species he was referring to? None other than the wolverine.
More than 60 years later, the same thought ran through my mind as I tracked through the foothills of Alberta’s Rocky Mountains. Would this be the day? Would I be able to catch even a brief glimpse of a wolverine’s bushy tail in the distance?

Coal Mining Update: Kicking the Can Down the Road (Again)
The message from the year-long public consultation is crystal clear. Albertans do not want more coal mining in the Eastern Slopes. They want this special region to be protected. If you agree, please write to Minister Savage and urge her to take meaningful action now: minister.energy@gov.ab.ca. The government should enact legislation that provides permanent protection for all ecologically important lands within the Eastern Slopes. Kicking the can down the road is not a reasonable alternative.

Shall We Gather at the River?
Irrigation and the Future of Southern Alberta’s Rivers
BY LORNE FITCH
In the heat dome and severe low flows of 2021, our canoe left smears of colour on several barely submerged boulders of one of Alberta’s prairie rivers. These low water levels had me reflecting on the recent scheme by southern Alberta’s irrigation sector to expand irrigated acreage. I thought of the old hymn, “Shall we Gather at the River.”
