Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Miti nemimwe miti yakasiyana-siyana inopfuura 1 700 inowanikwa mupaki iyi. Mamwe marudzi 170 anoonekwa semarudzi ekunze uye haasi omunzvimbomo. Pamarudzi masere emiti yemakoniferi akanyorwa, masango emiti yemipine yeLodgepole anofukidza 80% yenzvimbo dzose dzine masango. Mamwe makoniferi, akadai seSubalpine Fir, Engelmann Spruce, Rocky Mountain Douglas-fir uye Whitebark Pine, anowanikwa mumasango akapararira mupaki yacho yose. Kubva muna 2007, pine yewhitebark inotyisidzirwa nefungus inozivikanwa se white pine blister rust; zvisinei, izvi zvinonyanya kugumira kumasango ari kuchamhembe nekumadokero. MuYellowstone, inenge zvikamu zvinomwe kubva muzana zvemiti yemapine yakabatwa nefungus, zvichienzaniswa nechisimba chakakwana chiri kuchamhembe kwakadziva kumadokero kweMontana. Aspen inodedera nemiti yemusango ndiwo marudzi emiti inowanzosvava. Masango easpen akaderera zvikuru kubvira pakuvamba kwezana ramakore rechi20, asi masayendisiti paOregon State University anotaura nezvokudzorerwa kwazvino kweaspen nokuda kwokuunzwazve kwemhumhi izvo zvakachinja tsika dzokufudza dzembudzi dzomunzvimbomo.  Mubvunzo: Miti ipi inowanikwa mumiti yakasiyana-siyana iri mupaki yacho?
