Chugach

National Forest - Alaska

The Chugach National Forest is located in south central Alaska. Covering portions of Prince William Sound, the Kenai Peninsula and the Copper River Delta, it was formed in 1907 from part of a larger forest reserve. The Chugach includes extensive shorelines, glaciers, forests and rivers, much of which is untouched by roads or trails. It hosts numerous bird, mammal and marine species, including extensive shorebird habitat and a bald eagle population larger than the contiguous 48 states combined. Human industry in the forest includes extensive tourism and some mining and oil and gas operations.

The Chugach National Forest, one of two national forests in Alaska, serves as the “backyard” for over half of Alaska’s residents and is a destination for visitors. The lands that now make up the Chugach National Forest are home to the Alaska Native peoples including the Ahtna, Chugach, Dena’ina, and Eyak. The forest’s 5.4 million acres compares in size with the state of New Hampshire and comprises a landscape that includes portions of the Kenai Peninsula, Prince William Sound, and the Copper River Delta. The Chugach National Forest: • Is home to thousands of glaciers; • Contains over 3,500 miles of shoreline; • Includes the Copper River Delta, the largest contiguous wetlands complex on North America’s Pacific coast; • Includes the Nellie Juan-College Fiord Wilderness Study Area at almost a third of the forest acreage; • Produces 66 million salmon a year (11% of Pacific salmon production) via stream and lake habitat for all five species of pacific salmon; • Incorporates more than 180 miles of the Iditarod National Historic Trail known as the Southern Trek; and • Provides world-class recreation and fishing experiences. This visitor guide provides an overview of opportunities available to residents and visitors. These opportunities involve your own planning or could incorporate one of our outfitters and guides who are permitted to provide quality experiences within the forest (i.e. rafting, fishing, hunting, hiking). We also provide U.S. Forest Service ranger-led interpretive programs at our Begich, Boggs Visitor Center and Crooked Creek Information Site as well as at other locations on and off the forest in partnership with tourism businesses such as: • The Alaska Railroad Whistle Stop (Anchorage/Portage) • Major Marine Tours and Phillips Cruises (Whittier) • Portage Glacier Cruises (Portage Lake) Get Out and Explore! Hop on a train for a drive-free option into the Chugach National Forest, plan a multiple day trip to access remote primitive campsites, attend the famous Cordova Shorebird Festival, or visit the world-class interactive exhibits at Begich, Boggs Visitor Center. There is something for everyone on the Chugach. From the Kenai Peninsula to Prince William Sound, to the eastern shores of the Copper River Delta, the forest is full of special places.

Yet, today, these icy giants continue to exert their influence on the land. Their effects can be seen throughout South-central Alaska. Some of the more common signs of glacial activity include: U-shaped valleys Rocks embedded along the sides and bottom of the glacier create the same erosive qualities as a large piece of sandpaper, scouring the mountainside. This, along with silt and gravel deposited by the glacier, create steep-walled, flat-bottomed (or U-shaped) valleys l

Finding the mother lode! ‘Tis the stuff of miners’ dreams. Unlike professional gold seekers, recreational gold panners benefit mostly from the adventure. The entire family can share in the fun of prospecting and gold panning. In this booklet, we explain basic gold panning techniques, how to find gold, discuss mining rights and guidelines, and identify areas available for recreational panning on the Chugach National Forest portion of Alaska’s Kenai Peninsula. Recreational gold panning on lands withdrawn from mineral entry is not a mining activity—it is a privilege. Be aware that panning, sluicing, and suction dredging can adversely affect water quality, thereby impacting vegetation, fish, wildlife, and ultimately people. During the process of separating soil from minerals, silt may be washed into streams, creating turbid water. Fish, fish eggs, and the aquatic insects have difficulty living in heavily silted water because of its reduced oxygen supply. Avoid washing soil and vegetation into streams, and do not dig in stream banks. This increases silt in the stream and is also dangerous. Many banks are unstable and can slide without warning. To reduce silt, dig only in active stream gravels. Return rocks or boulders moved during your efforts to their original positions. Aquatic insects, an important food source for salmon, often make their homes under these rocks. A little care will help ensure a healthy water ecosystem for both miners and anglers. Good luck and good prospecting! 2 Gold – Significance and Use The brightness and ornamental beauty of gold have fascinated humans for at

Lichens of Alaska’s South Coast United States Department of Agriculture Forest Service Alaska Region R10-RG-190 July 2011 WHAT IS A LICHEN? Lichens are specialized fungi that “farm” algae as a food source. Unlike molds, mildews, and mushrooms that parasi ze or scavenge food from other organisms, the fungus of a lichen cul vates ny algae and / or blue-green bacteria (called cyanobacteria) within the fabric of interwoven fungal threads that form the body of the lichen (or thallus). The algae and cyanobacteria produce food for themselves and for the fungus by conver ng carbon dioxide and water into sugars using the sun’s energy (photosynthesis). Thus, a lichen is a combina on of two or some mes three organisms living together. Perhaps the most important contribu on of the fungus is to provide a protec ve habitat for the algae or cyanobacteria. The green or blue-green photosynthe c layer is o en visible between two white fungal layers if a piece of lichen thallus is torn off. Most lichen-forming fungi cannot exist without the photosynthe c partner because they have become dependent on them for survival. But in all cases, a fungus looks quite different in the lichenized form compared to its free-living form. HOW DO LICHENS REPRODUCE? Figure 1. Apothecia, fruiting bodies Figure 2. Soralia, small openings on thallus surface. Figure 3. Soredia, dust-like granules. Lichens sexually reproduce with frui ng bodies of various shapes and colors that can o en look like miniature mushrooms. These are called apothecia (Fig. 1) and contain spores that germinate and grow into the fungus. Each fungus must find the right photosynthe c partner in order to become a lichen. Lichens reproduce asexually in several ways. Some lichens have openings on the thallus surface called soralia (Fig. 2). Inside, ny dust-like granules called soredia (Fig. 3) are produced. Soredia contain algae and fungal cells that escape from the parent lichen and grow into a new lichen thallus. Other lichens produce outgrowths that break off and grow into the same lichen they came from. These are called isidia ( ny, cylindrical projec ons, Fig. 4) or lobules (li le flaps of ssue, Fig. 5). These structures are o en very important to no ce for the proper iden fica on of lichens. DIVERSITY AND ECOLOGY Lichens come in many shapes, Figure 4. Isidia, tiny projections. sizes, and colors. A lichen thallus has one of three general growth forms: foliose, fru cose, or crustose. Foliose lichens are leaf-like with different upper and lower surfaces. Fru cose lichens are hair-like or bushy with no Figure 5. Lobules, flaps of tissue. obvious difference between upper and lower surfaces. Crustose lichens are so closely a ached to a surface, like paint spots, that the lower surface is not easily observable. Lichens have specialized features enabling them to survive long periods of drought. In a dehydrated, inac ve state they can resist extreme high and low temperatures and s ll func on op mally whenever condi ons become just right. Well adapted for life in marginal habitats, lichens produce more than 500 unique biochemical compounds that serve to control light exposure, repel herbivores and microbes, and discourage compe on from plants. Among these are many pigments and an bio cs that are useful to humans. Lichens are considered to be nature’s pioneers because they colonize newly exposed surfaces. Lichens containing cyanobacteria fix their own nitrogen from the air into a form usable by other plants as a form of fer lizer. This form of nitrogen is released into the environment as rain washes over the lichens or when lichens die and fall to the ground. These lichen types tend to live in nitrogen-poor habitats such as bare rock surfaces, the forest canopy, or on sandy soils. Lichens provide food for many animals including flying squirrels, black-tailed deer, and mountain goats. Many invertebrates use lichens for food or for shelter. The diverse ecosystems along the south coast of Alaska provide abundant habitats for the more than 1,000 different lichens known to occur here. Some are very rare and cryp c. Many lichens are generalists and can grow in more than one habitat. Some lichens only grow in specific habitats such as upper dal rocks, conifer forests, alpine, or sandy soils near glaciers. LICHENS AND AIR QUALITY MONITORING Lichens are not protected by bark, nor do they possess an external waxy layer to prevent water loss like plant leaves. Lacking roots and other structures to transport food and water, lichens absorb moisture into the thallus directly from the humid air or rainfall, and can become quickly saturated like a sponge. Lichens dry out by losing moisture through evapora on when windy or dry condi ons exist. As drying occurs, elements and compounds that entered with moisture from the surrounding environment become concentrated in the lichen. During high rainfall periods, mobile nutrients and pollutants are slowly leached from the lichen. In this way lichen

Mushrooms of the National Forests in Alaska United States Department of Agriculture Forest Service Alaska Region R10 - RG -209 FEB 2013 Introduction 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. This brochure presents an introduction to mushrooms and illustrates a number of the more common and interesting of our local species to help Alaskans and visitors to better understand and enjoy our magnificent national forests. Unlike most plants, birds, and mammals, very few mushrooms have common names. Thus, while we have used common names where they exist, many of the species in this brochure can be referred to only by their scientific names. But, never fear. If you can talk with your kids about Tyrannosaurus rex, you can handle mushroom names! What is a mushroom? Mushrooms are produced by some fungi (singular: fungus), and their primary purpose is to make and spread tiny reproductive propagules called spores, which function much like plant seeds. After long being considered primitive plants, fungi now are accepted as their own kingdom. Unlike plants, fungi cannot make their own food, and their cell walls contain chitin rather than cellulose. Interestingly, chitin also is found in insect exoskeletons, providing evidence that the fungi are more closely related to animals (including us!) than they are to plants. Mushrooms arise from a mycelium (plural: mycelia), which is the actual “body” of the fungus and is comprised of a network of many tube-like microscopic filaments called hyphae (singular: hypha). Hyphae grow at their tips and are able to infiltrate a wide variety of substrates such as wood, leaf litter, soil, and even left-over pizza. Mushrooms to most people are umbrella-shaped structures with plate-like gills on the underside of their caps. However, besides the gilled mushrooms, there are others in many shapes and sizes, and they produce their spores in a variety of ways. Other major groups include chanterelles, boletes, polypores, spine-fungi, club- and coral-fungi, puffballs, jelly-fungi, cup-fungi, morels, false morels, and elfin saddles. Figure 1 shows the parts of a gilled mushroom. Learning the terminology will make it much easier for you to communicate with others about mushrooms and to make use of tools for identifying them. 2 U.S. Forest Service, Alaska Region Patch (remnant of universal veil) Cap (pileus) Cap margin Gills (lamellae) Ring (remnant of partial veil) Stalk (stipe) Volva (remnant of universal veil) Figure 1. Parts of a gilled mushroom. How do fungi reproduce? The primary purpose of a mushroom is to disperse spores into the environment in hopes that they will land in a location with suitable moisture, temperature, and nutrient conditions to germinate and grow into a new mycelium. Each mushroom is capable of producing anywhere from thousands to billions of spores, but only an incredibly tiny fraction of them are successful. Reproduction cannot occur unless the mycelium of one mating type merges with the mycelium of a compatible type. Once this has happened, sexual reproduction, including the formation of mushrooms and production of spores, can occur, completing the life cycle (Figure 2). Ecological Roles of Fungi While fungi are found in almost every environment, mushroom-forming species are especially prevalent in forests. There they play critical roles in nutrient cycling, soil aggregation, and water retention, as well as provide a food source for animals large and small. In general, the three main lifestyles of mushroom-producing fungi in forests are decomposer, mycorrhizal partner, and parasite. Mushrooms of the National Forests in Alaska 3 Figure 2. Life cycle of a typical mushroom fungus. Along with bacteria and other organisms, fungi break down all of the forest’s plant, animal, and microbial matter and make its components available for new generations of life. Fungi are particularly important in breaking down tough plant debris, as they are the only organisms capable of decomposing lignin, a major component of wood and other plant tissues. Many fungi form mycorrhizal (“fungus root”) associations with plants (Figure 3). This is mutually beneficial for both fungi and plants, as the plants receive nutrients such as nitrogen and phosphorus, as well as water and protection from soil pathogens, and the fungi get sugars produced by the plants. All of Alaska’s trees require mycorrhizal fungi for survival and growth, as do nearly all other plants. Relatively few parasitic fungi produce mushrooms. Most of them, such as honey mushrooms (genus Armillaria) and some polypores (such as Phaeolus schweini
Selected Invasive Plants of Alaska 2004 United States Department of Agriculture Forest Service, Alaska Region R10-TP-130B Produced by State & Private Forestry, Forest Health Protection When trying to identify an unknown plant, color photos often help. This pocket guide provides a selection of invasive plants found across Alaska today. This booklet is not intended to take the place of more comprehensive reference guides, but to help those unfamiliar with these species to begin to recognize them, as the first step towards taking action. Non-native invasive plants displace native vegetation, degrade wildlife habitat, and negatively affect human health, the economy, and the environment. Factors such as geographic isolation and harsh winters have protected Alaska from large-scale invasive plant infestations in the past. Recently, however, some of the most harmful noxious weeds of the lower 48 states have begun to grow and spread in Alaska. Many of the invasive plants featured in this booklet have been responsible for significant economic losses and environmental damage across North America over the past two centuries. Other species featured here (Siberian peashrub and European bird cherry) have been dependable components of Alaska’s urban landscape, but were included because they have recently been observed spreading aggressively into Alaskan wildlands and natural areas. There are many ways invasive plants are introduced to Alaska. Seeds and plant parts can travel in the root balls of nursery stock, in animal feed, tires, recreational equipment, or as components of wildflower seed mixes. Movement of people and equipment within natural areas and site-disturbing projects, such as road-building and construction, can create inroads for invasive plants. Alaskans have the chance to prevent invasive plant infestations before they become so widespread that control is costly and eradication impossible. This invasive plant booklet is designed to assist with identifying some of the most problematic species that are now moving along the roads, streams and beaches of Alaska. Thank you for doing your part to insure that these invasive plant species, and others like them, do not spread into Alaska's wildlands.

NATIONAL PARK SERVICE UNIVERSITY OF ALASKA FAIRBANKS Department of the Interior College of Rural Alaska Cooperative Extension Service Spotted Knapweed on Turnagain Arm In Alaska we are concentrating on prevention, early detection, and rapid response. Prevention: Keeping these invasive plant species from becoming established in Alaska is the highest priority. This booklet is a tool to help identify some of the species of greatest concern in Alaska. Early Detection & Rapid Response: Not only is it important to recognize these plants, but it is imperative that we find small infestations before they become too difficult to control. For example, spotted knapweed has been found five times within Alaska, but luckily these sites were discovered when the populations were less than 100 plants each. The Alaska Soil and Water Conservation Districts are in the process of forming “Cooperative Weed Management Areas” (CWMAs) across the state. The CWMAs will be actively involved in the detection, monitoring, and treatment of problematic invasive plant populations.
