In central and northern Alberta the arrival of spring is marked by the early flowering of the prairie crocus anemone; this member of the buttercup family has been recorded flowering as early as March, though April is the usual month for the general population. Other prairie flora known to flower early are the golden bean and wild rose. Members of the sunflower family blossom on the prairie in the summer months between July and September. The southern and east central parts of Alberta are covered by short prairie grass, which dries up as summer lengthens, to be replaced by hardy perennials such as the prairie coneflower, fleabane, and sage. Both yellow and white sweet clover can be found throughout the southern and central areas of the province.

The trees in the parkland region of the province grow in clumps and belts on the hillsides. These are largely deciduous, typically aspen, poplar, and willow. Many species of willow and other shrubs grow in virtually any terrain. On the north side of the North Saskatchewan River evergreen forests prevail for thousands of square kilometres. Aspen poplar, balsam poplar (or in some parts cottonwood), and paper birch are the primary large deciduous species. Conifers include jack pine, Rocky Mountain pine, lodgepole pine, both white and black spruce, and the deciduous conifer tamarack.

The four climatic regions (alpine, boreal forest, parkland, and prairie) of Alberta are home to many different species of animals. The south and central prairie was the land of the bison, commonly known as buffalo, its grasses providing pasture and breeding ground for millions of buffalo. The buffalo population was decimated during early settlement, but since then buffalo have made a comeback, living on farms and in parks all over Alberta.

Alberta is home to many large carnivores. Among them are the grizzly bears and black bears, which are found in the mountains and wooded regions. Smaller carnivores of the canine and feline families include coyotes, wolves, fox, lynx, bobcat and mountain lion (cougar).

Herbivorous animals are found throughout the province. Moose, mule deer, elk, and white-tailed deer are found in the wooded regions, and pronghorn can be found in the prairies of southern Alberta. Bighorn sheep and mountain goats live in the Rocky Mountains. Rabbits, porcupines, skunks, squirrels and many species of rodents and reptiles live in every corner of the province. Alberta is home to only one variety of venomous snake, the prairie rattlesnake.

Central and northern Alberta and the region farther north is the nesting ground of many migratory birds. Vast numbers of ducks, geese, swans and pelicans arrive in Alberta every spring and nest on or near one of the hundreds of small lakes that dot northern Alberta. Eagles, hawks, owls and crows are plentiful, and a huge variety of smaller seed and insect-eating birds can be found. Alberta, like other temperate regions, is home to mosquitoes, flies, wasps, and bees. Rivers and lakes are populated with pike, walleye, whitefish, rainbow, speckled, brown trout, and sturgeon. Bull trout, native to the province, is Alberta's provincial fish. Turtles are found in some water bodies in the southern part of the province. Frogs and salamanders are a few of the amphibians that make their homes in Alberta.

Alberta is the only province in Canada—as well as one of the few places in the world—that is free of Norwegian rats. Since the early 1950s, the Government of Alberta has operated a rat-control program, which has been so successful that only isolated instances of wild rat sightings are reported, usually of rats arriving in the province aboard trucks or by rail. In 2006, Alberta Agriculture reported zero findings of wild rats; the only rat interceptions have been domesticated rats that have been seized from their owners. It is illegal for individual Albertans to own or keep Norwegian rats of any description; the animals can only be kept in the province by zoos, universities and colleges, and recognized research institutions. In 2009, several rats were found and captured, in small pockets in southern Alberta, putting Alberta's rat-free status in jeopardy. A colony of rats were subsequently found in a landfill near Medicine Hat in 2012, and again in 2014.
