SPECIES: Salix pulchraIMPORTANCE come LIVESTOCK and WILDLIFE : Tealeaf pasture is an important moose browser in Alaska <23,26>. Itis also browsed by snowshoe hare and Dall lamb <35>.Willows in general are a wanted food and also building product of beaver<27>. Willow shoots, catkins, leaves, and buds are eaten by numeroussmall mammals and also birds <14>. In Alaska, willows are vital foodof ptarmigan <35>.PALATABILITY : Tealeaf willow is a preferred moose browse; however, that is lesspalatable 보다 Alaska pasture (Salix alaxensis), sandbar pasture (S.interior), and also littletree willow (S. Arbusculoides) <23>.NUTRITIONAL worth : Tealeaf pasture browse has actually moderate to relatively high moisture,protein, and caloric content. It provides a nutritious food supply forwintering moose <26>.COVER worth : Tealeaf pasture thickets administer cover because that wildlife. VALUE because that REHABILITATION of DISTURBED sites : In Alaska, numerous willow species are provided for wildlife habitatrestoration, streambank protection, and reclamation of web page disturbedby mining and also construction. Three general methods the planting willowson disturbed sites in north latitudes are <21,24,38>: (1) plantingstem cuttings, (2) transplanting containerized rooted cuttings orseedlings, and (3) planting majority of dormant branches.OTHER USES and also VALUES : All willows produce salacin, i beg your pardon is closely related chemically toaspirin. Aboriginal Americans used various preparations native willows totreat tooth ache, stomach ache, diarrhea, dysentery, and also dandruff <22>.Native Americans likewise used flexible willow stems because that making baskets,bows, arrows, scoops, and also fish trap <18>. Aboriginal Alaskan peoplesate young tealeaf willow leaves both raw and also cooked <35>. OTHER management CONSIDERATIONS : NO-ENTRY


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

Vegetative reproduction: Tealeaf willow sprouts indigenous the root crownif aboveground trunk are broken or ruined by cutting, flooding, orfire. Detached stem fragments kind adventitious root if castle remainmoist. Therefore portions of stems will certainly root naturally if hidden in moistsoil <14>.SITE qualities : Tealeaf pasture grows in arctic and also alpine tundra, open black andwhite spruce (Picea mariana, P. Glauca) woodlands, muskegs, and also sedgefens <1>. In open up spruce woodlands, tealeaf willow trees usuallyoccur as scattered individuals yet become more dense follow me riparianareas <26,35>. In open up black spruce woodlands, tealeaf pasture oftenattains highest possible cover in areas with shallow, perched water tables ~ above thesurface that permafrost <9>. In the mountains of interior Alaska, itoften forms considerable thickets above timberline <17>. It also formsextensive thickets in treeless bogs, and at treeline in northern Alaska<35>. In arctic tundra it grows on flow banks, islands, riverterraces, and also on rojo uplands <4>.SUCCESSIONAL status : Tealeaf willow is a ingredient of stable, shrub-dominated tundracommunities <3,4>. The is intolerant the shade, and also uncommon in climaxboreal forests, uneven they remain relatively open. Foote <12> reportedtealeaf willow arising in at an early stage successional stages followingwildfire in black spruce forests. The veached its greatest 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 to be not uncovered in suc#essionalterrace cOmmunities however grew only as scAttered people in climaxblack spruce-sphagnum moss stands <29>. These climax stands providedfavorable sites for ve`leaf willow because they to be relative?y openand wet dwe to comprehensive Permafrost.SAASONAL advance : Tealeaf pasture catkins appear in the beforehand spring prior to the leavesare totally expanded <35>. In Amaska, floWering generally occurs in Mayand June$ and also seeds typically mature in late May, June, !nd Kuly <7,31>.Seeds are dispersed soon0after ripening; dispersal occurs later on withincreasing lapitude and also elevation. Because that example, seeds room dispersedfrom late might to at an early stage June in the Fairbanks area but are no disperseduntil early August along the Meade flow <7>.


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


SPECIES: Salix pulchraIMMEDIATE FIRE result ON plant : Severe fires in white and black spruce woodlands where tealeaf willowgrows together scattered individuals deserve to kill willows by completely removingsoil essential layers and also charring the roots <39>. Much less severe fires onlytop-kill plants.DISCUSSION and also QUALIFICATION the FIRE effect : NO-ENTRYPLANT response TO FIRE : Tealeaf pasture sprouts from the source crown adhering to most fires.Sprouts develop much more rapidly 보다 seedlings do and also probably with over20 customs (50 cm) in elevation by the end of the very first growing season <37>.

DISCUSSION and QUALIFICATION that PLANT an answer : Tealeaf pasture is typical on recent burns in lowland black color spruceforests in inner Alaska. One 11-year-old burn had about 4,700tealeaf, Alaska, and grayleaf pasture stems every acre (11,600/ha), andlesser amounts of spruce and poplar <37>. Sampling countless burns inlowland black spruce species in internal Alaska, Foote <12> observed thattealeaf willow averaged 295 stems per acre (728/ha) top top 1- to5-year-old burns, and also 771 stems per acre (1,905/ha) on 5- come 30-year-oldburns. Its density probably boosts or remains consistent for up to 30years after a forest fire, but thereafter declines as young treesovertop that <12>.Since tealeaf willow seed are distributed in the summer and remainviable for only around one week, the season of a fire determines if itwill create during the an initial or succeeding postfire years <30,36>.Fire severity influence the mode of tealeaf pasture postfire recovery.Following irradiate fires that recovers quickly, sending up brand-new shoots fromundamaged source crowns. Few if any seedlings establish following thistype the burn due to the fact that organic soil layers, which prevent seedlingestablishment, are only partially consumed <32>. Following severefires, however, the main mode of recovery is seedling establishment.Severe fires the burn deep right into organic soils death willows but exposemineral soils, which provide excellent seedbeds. Ripe years after awildfire in a black spruce forest in interior Alaska, tealeafwillow cover got to 24 percent on scarified firelines within the burn,due to quick seedling establishment. In the main burn the 6-to8-inch-thick (15-20 cm) organic class was only partially burned. Here,tealeaf pasture reestablished through sprouting, and also cover after 9 yearswas just 3 percent <32>. Sheathe in surrounding unburned areas was 2 percent.FIRE management CONSIDERATIONS : Prescribed fire have the right to be provided to rejuvenate decadent willows.
