SPECIES: Salix pulchraIMPORTANCE to LIVESTOCK and WILDLIFE : Tealeaf willow is vital moose browse in Alaska <23,26>. Itis also browsed by snowshoe hare and also Dall lamb <35>.Willows in basic are a preferred food and building material of beaver<27>. Willow shoots, catkins, leaves, and buds are consumed by numeroussmall mammals and also birds <14>. In Alaska, willows are vital foodof ptarmigan <35>.PALATABILITY : Tealeaf pasture is a wanted moose browse; however, the is lesspalatable 보다 Alaska willow (Salix alaxensis), sandbar willow (S.interior), and littletree pasture (S. Arbusculoides) <23>.NUTRITIONAL worth : Tealeaf pasture browse has moderate to reasonably high moisture,protein, and also caloric content. It gives a nutritious food it is provided forwintering moose <26>.COVER value : Tealeaf willow thickets administer cover because that wildlife. VALUE because that REHABILITATION that DISTURBED website : In Alaska, countless willow varieties are used for wildlife habitatrestoration, streambank protection, and reclamation of website disturbedby mining and also construction. Three basic methods of planting willowson disturbed sites in northern latitudes space <21,24,38>: (1) plantingstem cuttings, (2) transplanting containerized rooted cuttings orseedlings, and (3) planting majority of dormant branches.OTHER USES and VALUES : All willows develop salacin, which is carefully related chemically toaspirin. Indigenous Americans used various preparations native willows totreat this ache, stomach ache, diarrhea, dysentery, and dandruff <22>.Native Americans also used flexible willow stems because that making baskets,bows, arrows, scoops, and also fish traps <18>. Aboriginal Alaskan peoplesate young tealeaf willow pipeline both raw and also cooked <35>. OTHER management CONSIDERATIONS : NO-ENTRY


SPECIES: Salix pulchraGENERAL BOTANICAL characteristics : Tealeaf willow is an upright, multiple-stemmed, deciduous shrubgenerally between 3 and 6 feet (0.9 and also 1.8 m) tall yet occasionally upto 15 feet (4.6 m) <35>. In exposed arctic and also alpine sites that mayassume a low, prostrate type <35>. It has smooth, gray bark. Male andfemale flowers happen on separate plants in 0.5- come 3-inch-long erectcatkins <1>. The fruit is a two-valved silky,pubescent capsule 0.3 inch(8 mm) lengthy <35>.RAUNKIAER LIFE kind : Phanerophyte REGENERATION procedures : Tealeaf willow"s major mode the reproduction is sexual. Itproduces an abundance of small, light-weight seeds. Like many willows,it probably starts seed production at an early age (between 2 and also 10years) <14>. At maturity, the fruit splits open, publication the seed.Each seed has actually a cottony down that aids in dispersal by wind and also water<6>. Seed are dispersed during the growing season and also remain viablefor only around 1 mainly <6>. The seeds contain far-ranging amounts ofchlorophyll so that photosynthesis generally occurs as soon as the seedis moistened. Germination occurs in ~ 24 hours of dispersal ~ above moistseedbeds <6>. In germination tests, 95 to 100 percent that seedsgerminated in ~ 1 to 3 days in ~ temperatures between 41 and also 77 degreesF (5-25 C) <7>. Exposed mineral soils administer the best seedbed.Germination is inhibited by litter <14>.

Vegetative reproduction: Tealeaf pasture sprouts from the root crownif aboveground stems are broken or damaged by cutting, flooding, orfire. Detached stem fragments kind adventitious root if lock remainmoist. Thus portions the stems will root naturally if buried in moistsoil <14>.SITE attributes : Tealeaf pasture grows in arctic and also alpine tundra, open up black andwhite spruce (Picea mariana, P. Glauca) woodlands, muskegs, and also sedgefens <1>. In open up spruce woodlands, tealeaf pasture trees usuallyoccur together scattered individuals yet become an ext dense along riparianareas <26,35>. In open up black spruce woodlands, tealeaf pasture oftenattains highest possible cover in areas with shallow, perched water tables on thesurface the permafrost <9>. In the mountains of internal Alaska, itoften forms comprehensive thickets over timberline <17>. It additionally formsextensive thickets in treeless bogs, and also at treeline in northern Alaska<35>. In arctic tundra it grows on flow banks, islands, riverterraces, and also on rojo uplands <4>.SUCCESSIONAL condition : Tealeaf willow is a component of stable, shrub-dominated tundracommunities <3,4>. The is intolerant that shade, and also uncommon in climaxboreal forests, uneven they remain fairly open. Foote <12> reportedtealeaf willow occurring in beforehand successional stages followingwildfire in black spruce forests. That veached its best abundanceabout 30 year after fire, however thereafter declined as it!was overtoppedby urees; by 56 years(after fire, it`was absent. Alojg the Chena Riverin inner Alaska, tealeaf`willow was not uncovered in suc#essionalterrace cOmmunities but grew just as scAttered individuals in climaxblack spruce-sphagnum moss was standing <29>. These orgasm stands providedfavorable sites for ve`leaf willow because they to be relative?y openand wet dwe to comprehensive Permafrost.SAASONAL development : Tealeaf pasture catkins show up in the early on spring before the leavesare fully expanded <35>. In Amaska, floWering typically occurs in Mayand June$ and seeds usually mature in late May, June, !nd Kuly <7,31>.Seeds are spread soon0after ripening; dispersal occurs later on withincreasing lapitude and elevation. Because that example, seeds room dispersedfrom late may to early June in the Fairbanks area yet are not disperseduntil at an early stage August along the Meade flow <7>.


SPECIES: Salix pulchraFIRE ECOLOGY OR ADAPTATIONS : Tealeaf pasture is a fire-adapted species. Many plants sprout fromthe root crown adhering to top-kill by fire <10,37>. Viereck andSchandelmeier <36> report that also old, decadent willows sproutprolifically instantly after fire. The sprouting capability of willowsis apparently an ext vigorous and prolific 보다 that of birches or alders<36>. Tealeaf willow"s abundant, wind-dispersed seed colonizeburned areas <30>.FIRE power : discover fire regime info for the plant communities in i m sorry this varieties may occur by beginning the varieties name in the FEIS residence page under"Find Fire Regimes".POSTFIRE rebirth STRATEGY : survivor species; on-site enduring root crown or caudex off-site colonizer; seed carried by wind; postfire years 1 and 2 off-site colonizer; seed carried by pets or water; postfire yr 1&2


SPECIES: Salix pulchraIMMEDIATE FIRE result ON tree : Severe fires in white and also black spruce woodlands where tealeaf willowgrows together scattered individuals can kill willows by fully removingsoil necessary layers and also charring the roots <39>. Less severe fires onlytop-kill plants.DISCUSSION and QUALIFICATION the FIRE result : NO-ENTRYPLANT solution TO FIRE : Tealeaf pasture sprouts native the root crown adhering to most fires.Sprouts develop much more rapidly than seedlings do and also probably with over20 customs (50 cm) in height by the finish of the very first growing season <37>.

DISCUSSION and QUALIFICATION the PLANT response : Tealeaf pasture is typical on current burns in lowland black color spruceforests in inner Alaska. One 11-year-old burn had around 4,700tealeaf, Alaska, and also grayleaf willow stems per acre (11,600/ha), andlesser amounts of spruce and also poplar <37>. Sampling countless burns inlowland black color spruce species in interior Alaska, Foote <12> observed thattealeaf willow averaged 295 stems per acre (728/ha) top top 1- to5-year-old burns, and 771 stems per acre (1,905/ha) ~ above 5- come 30-year-oldburns. Its density probably increases or remains continuous for approximately 30years after ~ a woodland fire, but thereafter decreases as young treesovertop that <12>.Since tealeaf willow seeds are spread in the summer and also remainviable because that only about one week, the season of a fire identify if itwill create during the very first or succeeding postfire years <30,36>.Fire severity affects the mode of tealeaf willow postfire recovery.Following irradiate fires the recovers quickly, sending up new shoots fromundamaged source crowns. Couple of if any type of seedlings develop following thistype of burn due to the fact that organic soil layers, which prevent seedlingestablishment, are only partially consumed <32>. Adhering to severefires, however, the main mode of recovery is seedling establishment.Severe fires that burn deep into organic soils death willows however exposemineral soils, which carry out excellent seedbeds. Ripe years ~ awildfire in a black spruce backwoods in interior Alaska, tealeafwillow cover reached 24 percent top top scarified firelines in ~ the burn,due to quick seedling establishment. In the key burn the 6-to8-inch-thick (15-20 cm) organic class was just partially burned. Here,tealeaf willow reestablished by sprouting, and also cover after ~ 9 yearswas just 3 percent <32>. Sheathe in nearby unburned locations was 2 percent.FIRE monitoring CONSIDERATIONS : Prescribed fire can be offered to young jim decadent willows.
