Uchishandisa ndima yacho, tsanangura chikonzero chikuru chakaita kuti mhashu dzomuRocky Mountain dziparare.
Context:Mhashu dzeRocky Mountain dzakaparadza mapurazi muMaine kubva muna 1743 kusvika muna 1756 uye muVermont muna 1797<unk>1798. Mhashu dzakava dambudziko guru muzana remakore rechi19, sezvo kurima kwakawedzera kumadokero munzvimbo dzaiwanzowanikwa nemhashu idzi. Kuputika kwakasiyana-siyana kwakamuka muna 1828, 1838, 1846, uye 1855, kuchikanganisa nzvimbo dziri kuMadokero. Denda rakashanyira Minnesota muna 1856<unk>1857 uye zvakare muna 1865, uye Nebraska yakatambura kutapurwa kwakadzokororwa pakati pa1856 na1874.   Katuni ya1875 yaHenry Worrall inoratidza varimi vokuKansas vachirwisana nemhashu huru Mapoka makuru okupedzisira emhashu dzeRocky Mountain akanga ari pakati pa1873 na1877, apo mhashu yacho yakakonzera kukuvadzwa kwezvirimwa kwemamiriyoni $200 muColorado, Kansas, Minnesota, Missouri, Nebraska nedzimwe nyika. Mumwe murimi akataura kuti mhashu dzacho dzaiita "serima guru jena, rakaita semafungu echando, richivharidzira zuva semhute". Mhashu hadzina kungodya uswa chete nezvirimwa zvinokosha, asiwo ganda, huni, mvere dzemakwai, uye - mumamiriro ezvinhu akaipisisa - kunyange zvipfeko zvaiva pamisana yevanhu. Zvitima dzimwe nguva zvaimiswa pashure pokutsvedza pamusoro pemapoka makuru emhashu dzakapunzikira pazvitima. Sezvo mhashu dzairamba dzichiwedzera, varimi vaiedza kudzidzora vachishandisa pfuti, moto (dzimwe nguva waivakirwa mumakomba kuti vapise mhashu dzakawanda sezvinobvira), vachidzisasa ne"hopperdozers", rudzi rwemudziyo wokurima waidhonzwa neshure kwemabhiza aiva nenhoo yairova mhashu dzaisvetuka dzichipinda mupani rine chepfu yemvura kana kuti mafuta, kunyange kudzisveta mumidziyo yakafanana nevhu rekuchenesa, asi zvose izvi pakupedzisira zvakanga zvisingabatsiri pakumisa mhashu. Charles Valentine Riley, nyanzvi yezvinomera yokuMissouri, akafunga nzira yokugadzira nayo mhashu dzakanyoroveswa nomunyu nepepper uye dzakabikwa mubhotoro. Zvokudya zvacho zvakatengeswa, asi vamwe vakataura kuti "vaizofa nenzara nokukurumidza sezvavaizodya zvisikwa izvozvo zvinotyisa". Varimi pakupedzisira vakapindura nesimba kukuparadzwa kweboka racho; mutemo weNebraska wa1877 wakataura kuti munhu upi noupi ane makore ari pakati pemakore 16 ne60 aifanira kushanda kweanenge mazuva maviri achibvisa mhashu panguva yokubuda mudanga kana kuti kutarisana nechiokomuhomwe che$10. Gore iroro Missouri yakapa mubayiro weUS$1 pabhushele remhashu dzakaunganidzwa muna March, masendi 50 pabhushele muna April, masendi 25 muna May, uye masendi 10 muna June. Mamwe matunhu eGreat Plains akapa mipiro yakafanana. Muma1880 varimi vakanga vapora zvakakwana kubva mumatambudziko avo emhashu kuti vakwanise kutumira ngoro dzakatakura chibage kuvanhu vakanga vawirwa nemafashamo muOhio. Vakatangawo kudyara gorosi raibva mumwaka wokutanga wezhizha, makonye asati asvika. Iyi miitiro mitsva yokurima yakaderedza zvinobudirira tyisidziro yamasvosve uye yakabetsera zvikuru kuparara kwamarudzi acho.  Zvinofungidzirwa kuti kurima uye kudiridza kwaiitwa nevagari vemo uyewo kutsikwa-tsikwa nemombe nedzimwe mhuka dzokurima pedyo nenzizi nenzizi dziri muMakomo eRombo zvakaparadza mazai avo munzvimbo dzavaigara, izvo pakupedzisira zvakaita kuti vafe. Semuenzaniso, mishumo kubva panguva iyi inoratidza kuti varimi vakauraya mazai anodarika zana nemakumi mashanu pamasendimita akaenzana pavakanga vachirima, vachipura kana kufashamira.: 11<unk>12 Zvaiita sekuti rudzi urwu rwairarama nekubereka mupririe kwenguva pfupi chete mumakore ekuzadza, nechizvarwa chimwe nechimwe chiri chidiki pane chakapfuura uye chichingozadza kure kure kubva kuRocky Mountains, nepo nzvimbo dzekubereka dzechigarire dzerudzi urwu dzaiita sedzakaganhurirwa kunzvimbo iri pakati pemakiromita matatu nemakiromita zviuru zvitatu zvevhu rine jecha padyo nenzizi muRocky Mountains, iyo yakabatana nenzvimbo dzinorimwa uye dzekufudza dzaishandiswa nevagari.  Nemhaka yokuti mhashu rudzi rwemhashu dzinobuda apo mhashu dzinenge dzawanda, zvaifungidzirwa kuti M. spretus ingangodaro isina kutsakatika, kuti "chikamu chega" chemhashu dzinofamba dzingagona kushanduka kuva mhashu yeRocky Mountain zvichipiwa mamiriro ezvinhu akakodzera ezvakatipoteredza; zvisinei, kuedza kubereka kunoshandisa marudzi akawanda emhashu munzvimbo dzine vanhu vakawanda kwakakundikana kuita kuti chipembenene chakakurumbira chivepo. Mamiriro ezvinhu eM. spretus semhando yakasiyana yakasimbiswa ne2004 kuongororwa kweDNA yemarudzi ekuNorth America erudzi rweMelanoplus.  Melanoplus spretus yakaziviswa zviri pamutemo kuti yakatsakatika neIUCN muna 2014. Zvave zvichiratidzwa kuti Eskimo curlew iri panjodzi yekutsakatika yakanyanya yaidya mhashu panguva yekufamba kwayo kwematsutso uye kuti kutsakatika kwayo kungave kwakawedzera kumanikidza pane huwandu hwe curlew huri kutodzikira kusanganisira kuvhima uye kushandurwa kwenzvimbo yayo yemasango kuita zvekurima.
Mhashu dzokuRocky Mountain dzakaparara nemhaka yokuti varimi vomunzvimbomo vaidiridza nokurima nzvimbo yadzo, izvo zvakaparadza mazai adzo zvikatungamirira kukufa kwadzo.
