The State of Oregon - An Introduction to the Beaver State from NETSTATE.COM The State of Oregon Rugged Southern Oregon Coastline The spectacular beauty of Oregon leaves no visitor untouched. The state is home to deep vast forests, volcanic peaks, fertile valleys, plateaus, and an incredibly rugged coastline. To stand on one of the cliffs overlooking the Pacific is awe-inspiring, and the irony of the name Pacific is obvious when the ocean thrashes the beaches and rocks below. Oregon also is home to the deepest lake in America. With a depth of 1,932 feet, Crater Lake is a sight not to be missed. Deep, deep blue on a brilliant day, surrounded by the evergreen forest, Crater Lake is a uniquely wondrous and beautiful piece of Oregon's gorgeous terrain. The largest reserves of standing timber in the country contribute to Oregon's status as the leading producer of timber and plywood. The state has consistently attempted to balance the needs of the timber industry with environmental concerns. Oregon State Capitol, Salem The origin of the name Oregon is not certain.

One theory has it that the name comes from the French Canadian word "ouragan" meaning "storm" or "hurricane." It's thought that the Columbia River was at one time called "the river of storms" by Canadian fur traders plying their trade in the area. Another suggestion is that the name of the state came from the Spanish word "orejon" meaning "big-ear." This was a term that was applied to many Indian tribes in the area. A third idea suggests that the name of this state comes from the Spanish word "orégano" for the wild sage which grows so vigorously in eastern Oregon. THE STATE NICKNAMES: The Beaver State Oregon is called "The Beaver State" because of the association of beavers with the early history of the state and because of the admirable qualities of intelligence, industry, and ingenuity that are associated with this animal. The beaver is the official state animal and is displayed on the Oregon state flag . The Web-foot State Anyone who's been to Oregon will surely understand that this nickname comes from the amount or rain that falls in the state, most of it in the western 1/3 of the state.

Precipitation can average from 40 to more than 180 inches a year in some areas. The Hard-case State or "The Land of Hard Cases" was a nickname that was given to Oregon because of the hardships encountered by early settlers in the area. The Sunset State Oregon was called "The Sunset State" because of its far west location. At the time Oregon joined the Union, in 1859, it was the most westerly of all the states. This position was lost when Washington joined the Union in 1889 and again when Alaska joined in 1959. Oregon - U.S. States - HISTORY.com Motto: She Flies With Her Own Wings Tree: Douglas Fir Bird: Western Meadowlark Interesting Facts Due to the high demand for beaver hats and coats and unregulated trapping during the early settlement years, beavers were nearly eliminated by the mid-19th century. Since then, proper management has allowed the semi-aquatic mammals to flourish once again. Known as the “Beaver State,” Oregon features a picture of a beaver on the back of its state flag.

Beginning in 1836, roughly 12,000 emigrants made the 2,000-mile trek from Independence, Missouri, to the Oregon Territory. Heavily traveled until 1884, the Oregon Trail was the most used of all routes in the westward expansion of the United States. Mount Hood, a dormant volcano that last erupted around 1865, is covered by 12 glaciers. At 11,239 feet, it is the tallest peak in Oregon. In November of 1986, the 80-mile-long Columbia River Gorge, which traverses the border between Oregon and Washington, was designated the country’s first National Scenic Area. Since the mixture of cool marine air on the western side of the Cascades and the drier air from the inland basin creates a natural wind tunnel, the gorge is considered to be one of the best places in the world for windsurfing. Oregon grows 99 percent of all hazelnuts produced in the United States. It is also the country’s leading producer of Christmas trees, with an output of more than 4.9 million trees in 2009.

Oregon’s Crater Lake, formed in the remnant of an ancient volcano, is the deepest lake in the United States. Tags Facts About Oregon History: 7 Things You Might Not Know Facts About Oregon History: 7 Things You Might Not Know By Diane DiPiero | Monday, 13 Apr 2015 10:18 AM Close A A The 33rd state to join the Union, Oregon is known today for its snow-capped mountains, river gorges, and other natural wonders. This serene atmosphere belies Oregon's complex history. Here are seven things you might not know about the Beaver State: 1. The Adams-Onis Treaty of 1819 settled several border disputes between the United States and Spain. One provision in the treaty required Spain to relinquish control of the Oregon country to the United States. The current southern border of Oregon is a result of the Adams-Onis Treaty, and the treaty was also critical in determining the U.S.-Mexico border, according to PBS. VOTE NOW: Is Oregon Gov. John Kitzhaber Doing a Good Job? 2. The Oregon Trail led settlers from Missouri to Oregon.

Early pioneers walked the 2,000-mile trail; by 1836, wagons carried people across this overland route. The final destination was the Willamette Valley in what is now Oregon. By the mid-1840s, there were so many emigrants settling Oregon that the British gave up their rights to the territory, according to the National Park System. 3. The Gold Rush of the mid-19th century eventually wound its way up California and into Oregon. By 1850, miners were striking gold along several of Oregon's rivers. The Gold Rush in the state came to an end in the late 1860s. 4. Oregon joined the Union on February 14, 1859. In its state constitution, Oregon declared itself to be a whites-only state. White male voters defeated the idea of allowing black residency by a resounding 8,640 to 1,081, according to the Oregon History Project . At the same time, slavery was not allowed in the new state. A referendum vote rescinding the wording in the constitution did not occur until 1926.

Oregon is known as the Beaver State; ironically, lax animal trapping rules severely decimated the state's beaver population in the 19th century, according to History.com . The beaver was able to make a comeback thanks to tighter regulations. Oregon pays homage to the native animal with a picture of a beaver on the reverse side of its flag. It is the only state flag to have images on both the front and the back. 6. Oregon has a state nut, the hazelnut, or filbert. Dorris Ranch became Oregon's first commercial filbert orchard and has been in operation for more than 100 years. 7. Visitors to Portland often visit the International Rose Test Garden. Begun in 1917, this is the oldest public garden in the United States devoted to testing new varieties of roses. More than 500 varieties of roses are said to bloom in the garden.

An American Beaver at home near the water. Animal, State ﻿The 1969 Legislature named the American Beaver (Castor canadensis) the Oregon state animal. Prized for its fur, the beaver was overtrapped by early settlers and eliminated from much of its original range. Through management and protection, the beaver has been reestablished in waterways throughout the state. The beaver has been referred to as “nature’s engineer,” and its dam-building activities are important to natural water flow and erosion control. Oregon is known as the “Beaver State.” The beaver is Oregon State University’s mascot. Also see related learning resource . Linus Pauling won two Nobel prizes.

Native throughout western North America, the bird has brown plumage with buff and black markings. Its underside is bright yellow with a black V-shape on the breast. The outer tail feathers are mainly white and are easily visible when it flies. The Western Meadowlark is known for its distinctive, flute-like song. Also see related learning resource . Beavers - Living with Wildlife | Washington Department of Fish & Wildlife Beavers For more information on the Living With Wildlife series, contact the WDFW Wildlife Program 360-902-2515 See also: Beaver Management Beavers (Castor canadensis) are the largest living rodents in North America, with adults averaging 40 pounds in weight and measuring more than 3 feet in length, including the tail.

These semi-aquatic mammals have webbed hind feet, large incisor teeth, and a broad, flat tail. Once among the most widely distributed mammals in North America, beavers were eliminated from much of their range in the late 1800s because of unregulated trapping. With a decline in the demand for beaver pelts, and with proper management, they became reestablished in much of their former range and are now common in many areas. Beavers are found where their preferred foods are in good supply—along rivers, and in small streams, lakes, marshes, and even roadside ditches containing adequate year-round water flow. In areas where deep, calm water is not available, beavers that have enough building material available will create ponds by building dams across creeks or other watercourses and impounding water. Beavers dams create habitat for many other animals and plants of Washington. In winter, deer and elk frequent beaver ponds to forage on shrubby plants that grow where beavers cut down trees for food or use to make their dams and lodges. Weasels, raccoons, and herons hunt frogs and other prey along the marshy edges of beaver ponds.

Migratory waterbirds use beaver ponds as nesting areas and resting stops during migration. Ducks and geese often nest on top of beaver lodges since they offer warmth and protection, especially when lodges are formed in the middle of a pond. The trees that die as a result of rising water levels attract insects, which in turn feed woodpeckers, whose holes later provide homes for other wildlife. Figure 1. The beaver’s incisors (front teeth) are harder on the front surface than on the back, and so the back wears faster. This creates a sharp edge that enables a beaver to easily cut through wood. (From Christensen and Larrison, Mammals of the Pacific Northwest: A Pictorial Introduction.) The beaver’s incisors (front teeth) are harder on the front surface than on the back, and so the back wears faster. This creates a sharp edge that enables a beaver to easily cut through wood. Like many rodents, beavers construct nesting dens for shelter and for protection against predators. These may be burrows in a riverbank or the more familiar lodges built in the water or on the shore (shown here).

However, the basic interior design varies little and consists of one or more underwater entrances, a feeding area, a dry nest den, and a source of fresh air. Facts about Washington’s Beavers Food and Feeding Habitats Beavers eat the leaves, inner bark, and twigs of aspen (a favorite food), alder, birch, cottonwood, willow, and other deciduous trees. Beavers also eat shrubs, ferns, aquatic plants, grasses, and crops, including corn and beans. Coniferous trees, such as fir and pine, are eaten occasionally; more often, beavers will girdle and kill these trees to encourage the growth of preferred food plants, or use them as dam building material. Beavers have large, sharp, upper and lower incisors, which are used to cut trees and peel bark while eating. The incisors grow their entire lives, but are worn down by grinding them together, tree cutting, and feeding. (Fig.1) Fermentation by special intestinal microorganisms allows beavers to digest 30 percent of the cellulose they ingest.

When the surface of the water is frozen, beavers eat bark and stems from a food “cache” (a safe storage place) they have anchored to the bottom of the waterway for winter use. They also swim out under the ice and retrieve the thick roots and stems of aquatic plants, such as pond lilies and cattails. Food caches are not found consistently where winters are comparatively mild, such as in the lowlands of western Washington. Click to enlarge Figure 2. Like many rodents, beavers construct nesting dens for shelter and for protection against predators. These may be burrows in a riverbank or the more familiar lodges built in the water or on the shore (shown here). However, the basic interior design varies little and consists of one or more underwater entrances, a feeding area, a dry nest den, and a source of fresh air. (Drawing by Jenifer Rees.) Beaver Dams Beavers flood areas for protection from predators, for access to their food supply, and to provide underwater entrances to their den. Flooded areas also wet the soil and promote the growth of favored foods (Fig. 3). Beavers living on water bodies that maintain a constant level (e.g., lakes, large rivers) do not build dams.

Dams are constructed and maintained with whatever materials are available—wood, stones, mud, and plant parts. They vary in size from a small accumulation of woody material to structures 10 feet high and over 165 feet wide. The feel and sound of flowing water stimulate beavers to build dams; however, they routinely let a leak in a dam flow freely, especially during times of high waters. Beavers keep their dams in good repair and will constantly enlarge the dams as the water level increases in their pond. A family of beavers may build and maintain one or several dams in their territory. In cold areas, dam maintenance is critical. Dams must be able to hold enough water so the pond won’t freeze to the bottom, which would eliminate access to the winter food supply. Lodges and Bank Dens Depending on the type of water body they occupy, beavers construct freestanding lodges or bank dens. Lodges and bank dens are used for safety, and a place to rest, stay warm, give birth, and raise young. Freestanding lodges are built in areas where the bank or water levels aren’t sufficient for a safe bank den.

Lodges consist of a mound of branches and logs, plastered with mud. One or more underwater openings lead to tunnels that meet at the center of the mound, where a single chamber is created. Bank dens are dug into the banks of streams and large ponds, and beavers may or may not build a lodge over them (Fig.2). Bank dens may also be located under stumps, logs, or docks. One family can have several lodges or bank dens, but will typically use only one den during winter. Reproduction and Family Structure A mated pair of beaver will live together for many years, sometimes for life. Beavers breed between January and March, and litters of one to eight kits (average four) are produced between April and June. The number of kits is related to the amount of food available (more food, more kits), and the female’s age. The female nurses the kits until they are weaned at 10 to 12 weeks of age. Most kits remain with the adults until they are almost two years old.

(Some leave at 11 months and a few females may stay until they are three years of age.) The kits then go off on their own in search of mates and suitable spots to begin colonies, which may be several miles away. Beavers live in colonies that may contain 2 to 12 individuals. The colony is usually made up of the adult breeding pair, the kits of the year, and kits of the previous year or years. Populations are limited by habitat availability, and the density will not exceed one colony per ½ mile under the best of conditions. Mortality and Longevity Because of their size, behavior, and habitat, beaver have few enemies. When foraging on shore or migrating overland, beavers are killed by bears, coyotes, bobcats, cougars, and dogs. Other identified causes of death are severe winter weather, winter starvation, disease, water fluctuations and floods, and falling trees. Humans remain the major predator of beavers. Historically, beavers have been one of the most commonly trapped furbearers. In Washington, from 1991 to 2000, an annual average of 5,289 beavers were trapped.

However, the average for the past three years has dropped to just over 1,000, due to RCW 77.15.194 . Beavers live 5 to 10 years in the wild. Viewing Beavers Beavers are nocturnal, but are occasionally active during the day. They do not hibernate, but are less active during winter, spending most of their time in the lodge or den. Probably no animal leaves more obvious signs of its presence than the beaver. Freshly cut trees and shrubs, and prominent dams and lodges are sure indicators of their activity. Look for signs of beavers during the day; look for the animals themselves before sunset or sunrise. Approach a beaver site slowly and downwind. (Beavers have poor eyesight but excellent hearing and sense of smell.) Look for a V-shaped series of ripples on the surface of calm water. A closer view with binoculars may reveal the nostrils, eyes, and ears of a beaver swimming. If you startle a beaver and it goes underwater, wait quietly in a secluded spot and chances are that it will reemerge within one or two minutes.

However, beavers are able to remain underwater for at least 15 minutes by slowing their heart rate. When seen in the water, beavers are often mistaken for muskrats. Try to get a look at the tail: Beavers have a broad, flat tail that doesn’t show behind them when swimming, whereas muskrats have a thin tail that is either held out of the water or sways back and forth on the water’s surface as the animal swims. Beavers stand their ground and should not be closely approached when cornered on land. They face the aggressor, rear up on their hind legs, and hiss or growl loudly before lunging forward to deliver extremely damaging bites. Harvest Sites Beavers cut down trees, shrubs, and other available vegetation for food and building materials. Large stumps are pointed, 1 to 2½ feet high, and sometimes the tree trunk is still attached. (Fig. 4) Tooth marks look like twin grooves, each groove measuring 1/8 inch or more. There will be a pile of wood chips on the ground around the base of recently felled trees. Limbs that are too large to be hauled off are typically stripped of bark over the course of several days.

The cut on small wood usually involves a 45-degree cut typical of rodents, but at a larger scale. Branches and twigs under ¾ inch in diameter are generally eaten entirely. Most harvesting is done within 165 feet of the water’s edge. In areas with few predators, but a lean food supply, toppled trees and other signs of feeding may be found twice that distance from the den site. Beavers transport woody material even farther through upstream and downstream sites. By late fall (earlier in cold winter areas of Washington), all family members concentrate on repairing and building up dams and the family lodge in preparation for winter. Harvesting is at its most intense level at this time of year. Figure 5. The paths beavers make where they enter and leave the water are called slides. (Photo by Russell Link.) Slides Slides are the paths beavers make where they enter and leave the water. They are 15 to 20 inches wide, at right angles to the shoreline, and have a slicked down or muddy appearance (Fig. 5). Channels Beavers construct channels or canal systems leading to their ponds, using them to float food—such as small, trimmed trees—from cutting sites.

Canals are also safe travel ways for swimming instead of walking. With receding water levels during summer, beaver activity shifts toward building and maintaining channels to access new food supplies. Channels often look man-made, have soft, muddy bottoms, and are filled with 15 to 25 inches of water. Food Storage Sites Beavers that live in cold climates store branches of food trees and shrubs for winter use by shoving them into the mud at the bottom of ponds or streams near the entrance to their bank den or lodge (Fig. 2). Droppings Beaver droppings are seldom found on land; those that are will commonly be found in the early morning at the water’s edge. Individual beaver droppings are usually cylindrical, up to 2½ inches long (sometimes shorter), and look as if they were formed of compressed sawdust. The diameter is an indication of the animal’s size, with 1 inch being average for adults. The color of fresh deposits is dark brown, with lighter-colored bits of undigested wood, all turning pale with age. Sounds In order to warn each other of danger, beavers slap their tails against the water, creating a loud splash.

Sounds also include whining (noises made by kits), a breathy greeting noise, and loud blowing when upset. A Beaver’s Tail The tail of a large beaver may be 15 inches long and 6 inches wide. It is covered with leathery scales and sparse, coarse hairs. The beaver’s tail has important uses both in the water and on land. In the water, the animal uses its flexible tail as a four-way rudder. When diving after being frightened, a beaver loudly slaps the water with its tail; the sound warns all beavers in the vicinity that danger is near, and perhaps serves to frighten potential predators. On land, the tail acts as a prop when a beaver is sitting or standing upright. It also serves as a counterbalance and support when a beaver is walking on its hind legs while carrying building materials with its teeth, front legs, and paws. Contrary to common belief, beavers do not use their tails to plaster mud on their dams. The tail stores fat, and because it is nearly hairless, releases body heat, helping the beaver to regulate its body temperature.

Preventing Conflicts Despite an appreciation for beavers and our best intentions to live with them, beavers can become a problem if their eating habits, and dam or den building activity, flood or damage property. Before beginning any beaver control action, assess the beaver problem fairly and objectively. Are beaver really causing damage or creating hardship requiring control action? The very presence of beavers is often seen as a problem when, in fact, the beavers are causing no harm. You should also determine the type of damage or problem the animals are causing, and then match the most appropriate and cost-effective controls to the situation. Once you have decided to control beaver damage, you have three control options: prevention, beaver translocation, or lethal control. To prevent conflicts or remedy existing problems: Choose and place plants carefully. Plant areas with Sitka spruce, elderberry, cascara, osoberry (Indian plum), ninebark, and twinberry, because they are not the beavers’ preferred food plants. Densely plant aspen, cottonwood, willow, spirea (hardhack), and red-twig dogwood because, once their roots are well established the upper parts of the plants often resprout after being eaten.

Planting preferred plants away from known beaver trails will limit losses. Note: Beavers do use plants as construction materials that they might not eat. Install barriers. The trunks of individual large trees can be loosely wrapped with 3 foot high, galvanized welded wire fencing, hardware cloth, or multiple layers of chicken wire (Fig. 6). Barriers can be painted to make them less noticeable. Welded wire fencing coated with green vinyl that helps the fencing blend in is also available. Lengths of corrugated plastic drainpipe can be attached around the trunks of narrow-diameter trees. Note: Dark-colored pipe can burn trunks in full sun; wider diameter pipe or pipe with holes in it may prevent overheating problems. Painting tree trunks with a sand and paint mix (2/3 cup masonry grade sand per quart of latex paint) has proven somewhat effective at protecting trees from beaver damage. The animals presumably don’t like the gritty texture. Note: Preventing access to food sources may force beavers to eat other nearby plants, including roses and other ornamentals. Figure 6. Various barriers can be used to protect plants from beaver damage.

All plants should be protected to at least 3 feet above ground—or the snow line—and inspected regularly. (Drawings by Jenifer Rees.) Surround groups of trees and shrubs with 3-foot high barriers made of galvanized, welded wire fencing or other sturdy material (Fig. 7). (A beaver’s weight will pull down chicken wire and similar lightweight material.) Stake the barriers to prevent beavers from pushing them to the side or entering from underneath. An electric fence with two hot wires suspended 8 and 12 inches off the ground is also effective at protecting groups of plants. Figure 7. Groups of plants can be protected from beaver damage by surrounding them with wire fencing. Protect large areas that border beaver habitat by installing 4-foot high field fencing. Keep the bottom of the fence flush to the ground, or include an 18-inch wide skirt on the beaver side of the fence, to prevent beavers from entering underneath. Groups of plants can be protected from beaver damage by surrounding them with wire fencing. Apply repellents. Commercial taste and odor repellents have provided mixed results, perhaps because they need to be reapplied often, particularly in moist weather.

Taste and odor repellents are most effective when applied at the first sign of damage, when other food is available, and during the dry season. Two repellents that have had some success are Big Game Repellent® and Plant-skydd®. (See “ Repellents ” in Deer for additional information.) Control the height of water behind a beaver dam to prevent flooding. It may be possible to make a small change in the depth of a beaver pond by installing a flow device at the intended depth, extending upstream and downstream of the dam. This keeps the rise in the water level at a minimum by using one or more plastic pipes to continually drain the pond area (see “Flexible Leveler” below. Click to enlarge). For leveling systems to work properly, you will have to have at least 3 feet of water in the pond area for the beaver to stay. The flow device can be constructed from plastic pipe measuring 4 to 12 inches in diameter, depending on the volume of water in the stream. The end extending upstream from the dam must be baffled to prevent beavers from damming or blocking the pipe. Beaver Deceiver Dam removal.

It is pointless to destroy a beaver dam because beavers (frequently many at one time) often begin rebuilding them immediately after they are removed. Furthermore, it may be illegal to remove a beaver dam without a permit (see “ Legal Status ”). Live Trapping and Moving Beavers Live trapping and moving beavers elsewhere (translocating) is often cost-prohibitive. Also, research has shown that beavers seldom survive relocation, and those that do often move great distances from the release site. However, in urban areas where lethal trapping may be illegal or unsafe, live trapping may be the only alternative. Hancock or Bailey suitcase-type traps are the most commonly used live trap. (Due to the weight and dangers associated with suitcase traps, it is recommended that only people experienced with these traps use them.) Some success has also come from using a 4 foot long cage trap set right at the water’s edge next to the beaver slide. Bait for live traps include freshly cut tree sprouts or branches of preferred foods, apples, and commercial scents and lures. If you are moving beavers to a different site, particularly a site where other beavers are not already present, there must be cooperation between adjacent landowners and local wildlife officials.

A cooperative evaluation of existing habitat quality and potential adverse beaver activity is also very important. (Expect beaver to cut and use a large number of trees for dam construction during the first year or two.) To help ensure the survival of beavers, the gradient of the watercourse at the release site should be less than 3 percent, and the site should have adequate food supply. Move beavers during their principal dam-building period, August to October. This will allow them time to gather a food cache, but limit their time to explore before having to settle in for the coming of winter. It may be helpful to provide beavers with a pickup-truck load of aspen or other trees to use as building material at or near the release site. This may encourage the beavers to stay nearby. See the handout Trapping Wildlife for additional information on trapping and moving beavers. Lethal Control Lethal control may become necessary when all efforts to dissuade problem beavers fail. Removing beavers is rarely a lasting solution since survivors have larger litters, and others will resettle good habitats. Lethal trapping has traditionally been the primary form of controlling beaver damage.

If you feel you need to have a beaver trapped, private individuals who work directly with property owners on a fee basis to resolve problem beaver situations can be hired. Call your local Fish and Wildlife office for contact information. See " Legal Status " and the handout Hiring a Wildlife Damage Control Company for additional information. Note: State wildlife offices do not provide animal removal services. Shooting beaver requires skilled marksmanship, but can be an effective control technique where it is safe. For safety considerations, shooting is generally limited to rural situations and is considered too hazardous in more populated areas, even if legal. Public Health Concerns Beavers can be infected with the bacterial disease tularemia. Tularemia is fatal to animals and is transmitted to them by ticks, biting flies, and via contaminated water. Animals with this disease may be sluggish, unable to run when disturbed, or appear tame. Tularemia may be transmitted to humans if they drink contaminated water, eat undercooked, infected meat, or allow an open cut to contact an infected animal. The most common source of tularemia for humans is to be cut or nicked by a knife when skinning or gutting an infected animal.

Humans can also get this disease via a tick bite, a biting fly, ingestion of contaminated water, or by inhaling dust from soil contaminated with the bacteria. A human who contracts tularemia commonly has a high temperature, headache, body ache, nausea, and sweats. A mild case may be confused with the flu and ignored. Humans can be easily treated with antibiotics. Beavers are among the few animals that regularly defecate in water, and their droppings (like those of humans and other mammals) may cause a flu-like infection when contaminated water is ingested. The technical name for this illness is “giardiasis.” It is more commonly referred to as “giardia”—derived from giardia, the single-cell protozoan that causes the disease. Another popular term, “beaver fever,” may be a misnomer. It has never been demonstrated that the type of giardia beavers carry causes giardiasis in humans. Giardia has been found in many animal species, including pets, wildlife, and livestock. Legal Status Because beavers’ legal status, trapping restrictions, and other information change, contact your local wildlife office for updates.

The beaver is classified as a furbearer ( WAC 232-12-007 ). A trapping license and open season are required to trap or shoot a beaver. The owner, the owner’s immediate family, an employee, or a tenant of property may shoot or trap a beaver on that property if a threat to crops exists ( RCW 77.36.030 ). In such cases, no special trapping permit is necessary for the use of live traps. However, a special trapping permit is required for the use of all traps other than live traps ( RCW 77.15.192 , 77.15.194 ; WAC 232-12-142 ). There are no exceptions for emergencies and no provisions for verbal approval. All special trapping permit applications must be in writing on a form available from the Department of Fish and Wildlife (WDFW).

It is unlawful to release a beaver anywhere within the state, other than on the property where it was legally trapped, without a permit to do so ( RCW 77.15.250 ; WAC 232-12-271 ). To remove or modify a beaver dam you must have a Hydraulic Project Approval (HPA)—a permit issued by WDFW for work that will use, obstruct, change, or divert the bed or flow of state waters ( RCW 77.55 ). A permit application can be obtained from your WDFW Regional Office or from the Hydraulic Project Approval (HPA) web page. In emergency situations (when an immediate threat to property or life exists), verbal approval from WDFW can be obtained for work necessary to solve the problem. A 24-hour hotline (360) 902-2537 is available for emergency calls during nonworking hours. During normal hours, contact your nearest WDFW Regional Office .
