Tiger Salamander (Ambystoma tigrinum)

The highest diversity of salamanders is found in Southeast United states, but Wyoming is unique to have their only native salamander as their state amphibian, the tiger salamander. These salamanders have several different color variations within the species, subspecies, and region, but typically are dark grey, brown or black with brownish markings (nwf.org). 

Tiger salamanders may be seen after heavy rains, but most of the year they are found burrowed underground. They mate during late winter or early spring at breeding ponds and eggs are laid between 24-48 hours after. After eggs hatch, tiger salamanders are able to live up to 14 years in the wild.

Indian Paintbrush (Castilleja sp.)

Indian Paintbrush (Castilleja sp.)

With over 200 species of Castilleja, this species of Indian Paintbrush is native to the United States. Wyoming’s state flower is specifically Castilleja linariaefolia, but we will focus on the species coccinea. Coccinea refers to the red petals that resemble cup-like structures. When we think of plants, we know they photosynthesize and get their energy from the direct sunlight, but these plants are hemiparasites, meaning that they get some of their nutrients from other organisms as well. Most of the time, they will parasitize the perennial grasses that accompany them (USFS), as well as sagebrush.

Like any other flowering plant, Indian Paintbrush rely on pollinators to help them reproduce year after year. Because of their interesting petal shape, ruby-throated hummingbirds are a great pollinator of the Indian Paintbrush in general, and other members of this genus. Since hummingbirds have the long, slim bill to reach the nectar, they are a perfect pollinator for these tubular-type flowers.

Gray Wolf (Canis lupus)

Gray Wolf (Canis lupus)

Despite what their name might suggest, gray wolves aren’t just gray. Their coats can vary between gray, black, white, and tan. They usually live in packs of two to over twenty wolves, communicating through scent, body language, and vocalizations. As a pack, they often hunt together to bring down large prey like bison, elk, and moose, and they also work together to raise their young pups. While it is possible to spot wolves in Grand Teton National Park, you are far more likely to view them in Northern Yellowstone at dawn or dusk, when they are most active. In GTNP, bring binoculars and keep an eye out while exploring sagebrush flats or when visiting the Elk Refuge – you might get lucky!

Wolves play an important role in the Greater Yellowstone Ecosystem (GYE), sharing complex relationships with other species in the area. Ecologists staying at the UW-NPS research station have had the unique opportunity to study the effects of wolf reintroduction in the GYE, and in our most recent annual reports, you can read about wolves’ impact on elk, moose, aspen, and beaver.
