The Alaska Region occupies the rugged, mountainous coast of the northeast Pacific Ocean. The maze of fjords and islands, streams and mountains characterizing the Region support a wide array of vegetation types ranging from vast wetlands to luxuriant temperate rainforests to magnificent alpine ecosystems.
There are only two national forests in the Alaska Region, the Tongass National Forest and the Chugach National Forest; however, they are the largest national forests in the Country. The Chugach surrounds Prince William Sound and is near Anchorage, Alaska's largest city. The Tongass National Forest includes the islands and mainland of southeastern Alaska and surrounds the towns of Ketchikan, Sitka, Juneau, Petersburg, Wrangell, Yakutat and Skagway.
Many of the plants in the Alaska Region produce spectacular wildflowers and colorful foliage, providing excellent opportunities to enjoy native plants from spring through autumn.
Botany Challenge 49
Posted June 18, 2013
The Falls Creek area of the Chugach State Park, Alaska, is immensely beautiful and includes verdant forests, species rich shrublands, and a lively stream. The trailhead is about 20 miles east of Anchorage on the Seward Highway. On the evening of June 13, 2013, “Botany Challenge 49” was held. The hiking group sought to identify 49 species of native plants (Alaska being the 49th state) and to note the phenological state of each (vegetative, flowering, fruiting). There were eleven participants (9 people and 2 dogs) in the botany challenge event, which extended from sea level to about 1,200 feet elevation along the Falls Creek Trail in Chugach State Park.

Mushrooms of the National Forests in Alaska (PDF, 2.9 MB)
The coastal temperate rainforests of the Tongass and Chugach national forests often produce prolific fruitings of mushrooms in late summer and fall. For many Alaskans, mushrooms are a source of food. For others, they are a source of pigments for dyeing wool and other natural fibers. Still others merely enjoy their beauty. However, all Alaskans should appreciate these fungi for, without them, there would be no forests here.

Ferns of the National Forests in Alaska (PDF, 4.2 MB)
Ferns abound in Alaska's two national forests, the Chugach and the Tongass, which are situated on the southcentral and southeastern coast respectively. These forests contain myriad habitats where ferns thrive. Most showy are the ferns occupying the forest floor of temperate rainforest habitats. However, ferns grow in nearly all non-forested habitats such as beach meadows, wet meadows, alpine meadows, high alpine, and talus slopes. The cool, wet climate highly influenced by the Pacific Ocean creates ideal growing conditions for ferns.
