Y Naturiaethwr

o’r unig safle sy’n weddill yn Iwerddon.
Gellid defnyddio’r un technegau i
blanhigion arfordirol coll eraill - er y byddai
gofyn cyrchu hadau o fannau pellach yn
achos rhai ohonynt. Ond pwy a ŵyr ?
Hwyrach y gwelir dychwelyd ambell
blanhigyn prin i draethau Môn. Yn ôl
patrwm pethau gallai traethau gorllewin yr
ynys fod yn lle da i chwilio.
