Quaking aspen is a minor but widespread forest type of interior Alaska. The quaking aspen grows well in acidic, loamy, moist, sandy, well-drained and clay soils. Quaking aspen have a wider range than any other North American tree. of the boreal zone. The FROSTFIRE experimental fire during 8 to 15 July 1999 burned about one-third of a subbasin in the Caribou Poker Creeks Research Watershed. Quaking Aspen – Populus tremuloides Black cottonwood (Poplus balsamifera subsp. Focus on Denali & Kenai Fjords. In some places, the fires burned into the roots of the deciduous trees, but in other places, the deciduous trees were top-killed or only slightly damaged [33]. The combination of more frequent fires and a warming climate may favor quaking aspen, balsam poplar, paper birch, and other birches, allowing these deciduous trees to establish on boreal sites that were formerly dominated by spruces [8,46,56,64,99]. Select from premium Quaking Aspen Alaska of the highest quality. Quaking aspen and balsam poplar communities usually do not burn except in drought years [26]. Quaking Aspen is the most widely distributed tree species in North America, ranging from Alaska to Colorado, and east across Canada to New England. No information was available on this topic as of 2014. The sections below provide discussions and documentation of historical fire regimes in Alaskan quaking aspen and balsam poplar communities. They grow in Alaska and Canada, all the way south to Mexico. Stands are generally confined to narrow bands along rivers, although some balsam poplar stands along the Tanana, Yukon, and Kuskokwin rivers are several kilometers wide [24]. Discover the optimal month due to daylight, temperature, and rain. LIMITATIONS OF INFORMATION Sites with >4 inches (10 cm) of organic soil remaining after fire will succeed to black spruce stands, with permafrost eventually re-forming [6]. Stands are most productive before white spruce replaces balsam poplar as the canopy dominant [101]. The range of Quaking Aspen is restricted to areas where annual precipitation exceeds evapotranspiration. The latter experts did not speculate on whether stand-replacement surface or crown fire was typical for balsam poplar communities. single family home built in that sold on 09/12/2016. In less severe fire years, average fire size was 19,000 acres (7,800 ha), and no fires were >500,000 acres (200,000 ha) [52]. Call (907) 339-0118 Email alyeskalandscape@gmail.com. ages of 4 quaking aspen stands across ~40 ha on northwest side of dome (15-60 quaking aspen/stand sampled); mosaic of black spruce, quaking aspen, & paper birch boreal forest stands; quaking aspen on warm sites [, Yukon Flats Wildlife Refuge, eastern interior. Posts: 3. Black cottonwood (P. trichocarpa)- quaking aspen hybrids occur rarely in Alaska . Likelihood of stand-replacement fire increases as conifers increase [21]. Based on the Fine Fuel Moisture Code of the FWI, areas near Fairbanks were within prescription for burning during 7 of 25 years (1963-1995) . Quaking aspen, paper birch, and balsam poplar were present, but the specific deciduous mix was not described in the study. Comments. In Alaska, the Canadian Forest Fire Weather Index (FWI) system is used to track effects of weather on fuel moisture conditions. USDA, Euro-Americans documented ignition and use of fire by Native Alaskans during the settlement period (1867-1914) [77]. Balsam poplar may codominate. Since balsam poplar and white spruce are common along large streams [74,96], this omission fails to capture many white spruce-balsam poplar communities. Quaking aspen, bigtooth aspen, European aspen (P. tremula), and three Asian species are closely related and sometimes classed together as a single, circumglobal superspecies (see Peterson and Peterson 1992). They withstand such a wide range of climatic conditions by growing at lower altitudes in the north and higher altitudes in the south. Balsam poplar: ... Distribution: quaking aspen grows in more states than any other tree. For quaking aspen, they include these BpS groups: Balsam poplar: Riverbottoms of interior Alaska seldom burn because soils are moist [97], the vegetation is relatively nonflammable [25,55,97], and such sites are often adjacent to sloughs and oxbow lakes [97] that break up fire continuity. Let us simplify it for you, How much does an Alaska summer vacation cost? If they do burn, they typically comprise low- and mixed-severity patches of the mosaic [16]. LANDFIRE models showed severe and mixed-severity fires in quaking aspen and mixed-deciduous communities, but not low-severity fire. Relationships: There are about 15 species of Populus (Poplars, Cottonwoods and Aspens) native to North America. It is common on all aspects in the western mountains of the United States and grows well wherever soil moisture is not limiting. Soils are relatively warm in balsam poplar forests, soil nutrients are readily available, and soil water is available during most—if not all—of the growing season [97]. It grows from Alaska shrubs dominate the shrub layer; tall shrubs are intermittent. A study in Alberta found fire-return intervals of 20 to 30 years for balsam poplar stands [78], suggesting placement in Fire Regime Group I (frequent, low-severity fire). Mature stands (60-70 years) have a closed canopy of quaking aspen and a subcanopy of black spruce. All of its names refer to how the leaves will quiver with the slightest breeze. Most fires (87%) were <300 acres (100 ha); 12.5% were 300 to 50,000 acres (120-20,200 ha); and 0.5% were >50,000 acres (Alaska Interagency Fire Management Plan 1984 cited in [31]). For balsam poplar, these are likely adaptations to flooding and ice scouring rather than fire [16]. Quaking Aspen leaves turn bright yellow in fall before falling and leaving its bark on display as winter interest. In midsuccession, quaking aspen often occurs in deciduous-conifer stands with paper birch, balsam poplar, and spruces [69]. Most of those were conducted in the northeastern part of the state. In the western United States, this tree rarely survives at elevation… Fires at shorter intervals strongly favor quaking aspen [34]. On lowlands of the Kenai Peninsula, scattered quaking aspen stands within a black spruce forest were <50 years old. Severe fire that results in permafrost melt can result in a type shift from black spruce to quaking aspen [48]. Nursery Hours. A few isolated stands occur on northern foothills of the Brooks Range. Use our calculator to find out, Stay casual, dress in layers, and get proper footwear, Guides to the best locations around the state to view wildlife. Car, train, or group tour. 7-10 days is the most common. Quaking aspen self-prunes [34] and the shrub layer is often sparse [34], so fires that crown in adjacent spruce stands usually burn around quaking aspen stands [34]. Its distribution may be expanding in boreal regions. Alaskan taiga usually burns in mosaics, with low- to high-severity and unburned patches [31,39,96] such as that shown in Figure 6 below. The Alaska Railroad is your transportation method. Balsam poplar: Balsam poplar stands are most common on the floodplains of interior, south-central, and southwestern Alaska, especially along major rivers of interior Alaska [31,87,94,96]. This section summarizes fire regime information available in the scientific literature as of 2014. Balsam poplar forests are usually seral, succeeding to white or black spruce forests. Mixed deciduous-conifer stands often have mixed-severity fires. A patchy surface burn on FROSTFIRE's experimental site (see Fire pattern below). White spruce [52,67,92] or black spruce [56,67] generally replace quaking aspen successionally around postfire year 70 to 80 [29,34]. Third-order streamside communities are missing from the Biophysical descriptions and models of white spruce-balsam poplar floodplain types. Except for the woodland, these communities are scattered throughout northwestern, interior, south-central, southwestern Alaska [94]. Another study of fire records of Alaskan taiga from 1940 to the 1990s found most large fires (73%) occurred during 10 severe fire seasons. LANDFIRE assigns low- [60] and high-elevation [59] boreal dry aspen-steppe bluff communities to Fire Regime Group III (35-200 years, mixed severity) based on expert opinion; the literature can provide no refinement of this estimate. Quaking aspen is a small- to medium-sized, fast-growing, and short-lived tree that grows about 20–25 m (66–82 ft.) tall. Native Alaskans and Euro-Americans ignited fires historically. In pure quaking aspen communities, fires are usually of low severity in stands of all ages [21]. Experts suggest that balsam polar stands probably experience low-severity surface [16] and severe, stand-replacement [66] fire. The species occurs throughout boreal and subboreal Alaska, excluding the western half of the Alaska Peninsula and portions of the Alaska Panhandle [ 42, 88 ]. Common names are used throughout this Fire Regime Synthesis. *MRFI=mean fire-return interval. ages of 56 quaking aspen & ~35 white spruces determed on a ~150-ha riparian sites w/ 8 terraces, 2 terraces were white spruce-balsam poplar; boreal white spruce-balsam poplar-quaking aspen/russet buffaloberry/lichen riparian forests on low terraces [. Quaking aspen occurs across Canada in all provinces and territories, with the possible exception of Nunavut. Here, a firefighter sprays a hot spot during the 2006 Parks Highway Wildfire near Nenana. When low-severity fires do not kill conifers in the understory, conifers may replace quaking aspen successionally [11,81]. Please try again. Highlights plus less visited destinations. The leaves attach to branches via a long and flattened petiole, so that even the slightest breeze causes the leaves to flutter. However, in the overstory, more biomass burned in black spruce than in white spruce stands, and more burned in white spruce than in quaking aspen stands [50]. Before decaying, the leaf litter may be thick [, quaking aspen-black spruce/bunchberry. Aspen: Quaking Aspen grows across the interior and southcentral Alaska. Quaking aspen forests cover an estimated 2% [ 5, 97] to 11% [ 43] of interior Alaska's … Figure 4. In the United States, it can be found as far north as the northern foothills of the Brooks Range in Alaska, where road margins and gravel pads provide islands of well-drained habitat in a region where soils are often waterlogged due to underlying permafrost. Compared to the 1940s and 1950s, fire frequency increased in interior Alaska during the 1960s-1990s. A few scattered populations occur farther south in Mexico to Guanajuato [].Quaking aspen is distributed fairly continuously in the East. across 2 subbasins, ages of 4-47 trees determined on 21 sites; mosaic of black spruce, white spruce, & quaking aspen-paper birch boreal forests; paper birch-quaking aspen on south-facing slopes [, Riley Creek near the Nenana River, south-interior Alaska. Figure 1. Moderate-severity fire was documented in only 1 study [33]. Deciduous forests tend to retain more heat but use more water than conifer forests. Quaking aspen-paper birch occurred on south-facing slopes lacking permafrost. The leaves shimmer and "quake" in the breeze displaying a spectacular show and a great fluttering sound. Black spruce dominance was positively correlated with sites that burned at low severity and had deep residual organic layers (P<0.001) [84]. Quaking Aspen You'll find Quaking Aspens throughout Alaska, especially in mountainous areas and locations that receive better drainage. As with upland forests, quaking aspen is seral to spruce in riparian zones. the understory; cow parsnip and bluejoint reedgrass dominate the ground layer. In deciduous-spruce forest mosaics, fires typically burn in mosaic patterns, with quaking aspen and paper birch-quaking aspen stands either burning at low severity or not burning at all, and spruce stands experiencing stand-replacing crown fire. A few researchers have published widely divergent expert opinions on fire regimes of Alaskan balsam poplar. Compared to conifer forests, soil moisture content is lower, soil nutrient levels are higher, and the litter layer is thinner [89]. But for much of its range, it only grows along rivers and streams, avoiding the hot, dry territory they travel through. Silverberry and shrubby cinquefoil dominate Quaking aspen is the most widely distributed tree in North America. It sprouts from the roots [18,96] and establishes from seed [53] after stand-replacement fire. To date (2014), fire history studies of balsam poplar forests were few. I have an acre of land in Fairbanks, Alaska. The moss layer is sparse Cronan and others [16] noted that low-severity fires in riparian zones may leave little evidence of their passing, and low-severity fires may burn in balsam poplar communities more often than realized. Very moist black spruce sites where fire has exposed mineral soil are most likely to succeed to deciduous species in early postfire landscapes. This is generally after about postdisturbance year 100 [30]. Sites with moderately moist (5%-30% soil moisture content) mineral soil will likely transition to mixed deciduous-black spruce forest [45]. Climate was drier and fires more frequent during that time (10,700-8,500 BP; MFRI*=77 years) than during the early Pleistocene (13,000 BP; MFRI=138 years), when the site was a tundra grassland [2]. Mature quaking aspen stands are rare to infrequent on floodplains of interior Alaska [29,104]. From 1956 to 1965, 21% of wildfires statewide were in deciduous-conifer forests, 36% percent were in conifer forests, and 29% were in tundra [4]. LANDFIRE's [63] list of quaking aspen and balsam poplar Biophysical Settings and links to their descriptions are provided in Appendix A. 2-5 day small ship explorations. Open by appointment only. On 6 sites in the Tanana River valley, wildfires removed most of the litter, moss, and humic layers in quaking aspen and white spruce stands but not in black spruce stands. High-elevation quaking aspen-steppe bluff types usually have fewer understory and surface fuels than similar low-elevation types. In particular, high-severity fires will likely favor quaking aspen and birches over spruces [8]. Fire regimes of quaking aspen communities of Alaska were not well documented as of 2014. Duff moisture fell within the acceptable range on 11 May or later. fire; at that stage, splendid feather moss and other feather mosses dominate the ground layer. USDI, National Park Service photo. Large fires occurred in drought years, when several small fires would usually merge into a large fire [31]. Balsam poplar's thick bark allows it to survive low-severity surface fire [16,32,35,66], and it sprouts from the roots and establishes from seed after stand-replacement fire [16,83]. Floods, not fires, are the primary disturbances in balsam poplar stands [66]. They love cold weather and are thus found at higher elevations and in northern latitudes. Wildfires in quaking aspen forests are usually ignited by summer lightning and occur in drought years. The slightest breeze sets the foliage aflutter—green in summer, pretty gold in fall. Quaking Aspen Of all the native trees in North America, quaking aspen (Populus tremuloides) has the greatest distribution. in Alaska. Viereck and others [94] reported that the oldest balsam poplar stands they found in Alaska were about 200 years old, but most stands were replaced successionally about 100 years after disturbance [94]. (POP-yu-lus trem-yu-low-EYE-deez) Names: Quaking Aspen is sometimes called Trembling Aspen. Small balsam poplar stands occur on timberline slopes throughout boreal Alaska [94]. During these severe fire seasons, fires averaged 50,200 acres (20,300 ha). In western Alaska, balsam poplar occurs in isolated clumps as far as the Seward Peninsula [97,98]. forests dominated the landscape from about 10,300 to 8,000 BP, while white spruce was dominant from around 8,000 to 5,500 BP [38]. Quaking aspens are the most widely distributed tree species in North America. It occurs throughout boreal interior and much of subboreal Alaska. Mary Beth. You'll find Quaking Aspens throughout Alaska, especially in mountainous areas and locations that receive better drainage. balsam poplar/thinleaf alder/bluejoint reedgrass; 60%-100% canopy closure, balsam poplar/thinleaf alder/prickly rose/horsetails; 60%-100% canopy closure, balsam poplar/Barclay's willow/cow parsnip; 60%-100% canopy closure, balsam poplar/willows-alders/herb; 60%-100% canopy closure, balsam poplar/alders-willows/prickly rose/horsetails/wintergreens; 60%-100% canopy closure, balsam poplar/kinnikinnick/felt lichens; 60%-100% canopy closure, balsam poplar/willows-alders/reedgrasses; 25%-60% canopy closure, balsam poplar/halberd willow-russet buffaloberry/fireweed/splendid feather moss-Schreber's moss; 25%-60% canopy closure, balsam poplar/thinleaf alder/horsetails; ; 25%-60% canopy closure. Forest Service photo. SUMMARY Early-seral quaking aspen stands are often dense, pure [67,94], and even-aged, with quaking aspen density decreasing with time since fire. Figure 6. On the Tanana River floodplain, Zasada [104] observed that although mature quaking aspens were scarce, quaking aspen seedlings were common. Previous periods of global warming have favored quaking aspen expansion in Alaska. This type is common in mountain ranges of south-central Alaska and near the western and northern limits LANDFIRE's [61] placement of boreal mesic paper birch-quaking aspen forest in Fire Regime Group IV dominated the landscape [41,72] (see Table 2B). quaking aspen/highbush cranberry/twinflower. Quaking aspen and poplars apparently dominated larger portions of interior Alaska during the early Holocene than at present [37,38,40]. This species is native to the Chicago region according to Swink and Wilhelm's Plants of the Chicago Region , with updates made according to current research. Lutz [66] reported that severe fire tends to maintain balsam poplar stands, while frequent low-severity fire tends to maintain balsam poplar-white spruce stands. In deciduous-conifer stands, the probability of crowning increases with the proportion of conifers (usually spruces) [81]. As of 2014, there were few fire studies of quaking aspen and balsam poplar communities in Alaska. A few large fires account for most acreage burned in interior Alaska [52]. Leaf litter dries out earlier in deciduous than in conifer forests, so the fire season may be longer in quaking aspen and balsam poplar than in spruce forests [93].

It is frequently important or codominant in white spruce forests [29,34], and it may codominate with black spruce on warm sites [29]. Canopy cover ranges It is a member of the poplar family, and its scientific name, Populus tremuloides, can give some indication of one of its characteristics, even if you do not know Latin. Table 2 Alaska's fire records only date back to the 1940s [24], and records may be missing or incomplete [20]. The landscape was a black spruce/feather moss and quaking aspen-paper birch mosaic.
