An tIora Glas
Tugadh ioraí glasa isteach go Castleforbes, Contae An Longfoirt i 1911 agus tá a sliocht tar éis leathadh amach ar fud oirthear na tíre ó shin. Tá siad le fáil go coitianta i bpáirceanna sna bailte móra. Ní amháin go n-itheann siad dearcáin ach itheann siad coirt agus bachlóga freisin agus sa chaoi sin déanann siad dochar cuibheasach mór do chrainn.
Grey Squirrel
Grey squirrels were introduced to Castleforbes, Co Longford in 1911 and have since spread over the eastern half of the country. They are very common in town parks. As well as eating acorns, they eat bark and buds and so do considerable damage to trees.
