Mashizha ayo akasvibirira-egirini anoita kuti asanyanya kuoma; panguva yekusanaya kwemvura, ruvara rwemashizha rwunonyanya kuoneka. Miti inogonawo kudonha mashizha ayo muzhizha panzvimbo pokudonha mumakore akaoma, asi kazhinji inopfuurira kukudziridza makonye ayo mukupera kwematsutso. Kusanaya kwemvura kungaita kuti miti irege kutumbuka muchirimo.  Vagari vomunyika yeCalifornia vaiwanzounganidza zviyo zveQuercus douglasii, zvavaifunga kuti zvinonaka, uye vaizozvigadzira kuva furawa yezviyo. Vaigadzira tswanda nemiti yemiouki yebhuruu, midziyo yakadai semabhodhoro nemiti yacho, uye dhayi nemakwati. Mune zvokutengeserana, muti womuouki unonzi blue oak unonyanya kushandiswa sehundi.
