Ann an Alba tha craobhan cho sean, cho àrd is inntinneach sa th’air an t-saoghal. Sa phrògram seo tha eòlaiche nàdair, Alison Ní Dhorchaidhe, a’coimhead craobhan suidhichte nar n-eachdraidh, ach an tuig i dè tha gam fàgail sònraichte. A’chraobh is sine tha beò ann am Breatainn, agus ’s dòcha san Roinn Eòrpa, iubhar Fartairchill: thathar a’meas a h-aois eadar dà mhìle is còig mìle bliadhna – ach chì Alison cuideachd tochailt craoibhe ann am Muile a tha trì fichead muillionn bliadhna a dh’aois.

Tha craobhan sònraichte àrd ann an Gleann na Rèilige – an learag is àirde, an teile is àirde, agus ’s dòcha a’chraobh is àirde buileach ann am Breatainn, giuthas Dhùghlais. Tha Alison cuideachd a’cluinntinn mun bheul-aithris tha buntainn ri craobhan dùthchasach, mun eachdraidh sgrìobhte ann an cearcaill an stuic, agus mun àite th’aig coillteireachd ann an àrainneachd agus eaconomaidh na h-Alba.

Scotland is home to some of the tallest, oldest and most fascinating trees in the world. Nature enthusiast Alison Ni Dhorchaidhe visits heritage trees across the country to discover what it is that makes them so special.

The oldest living tree in the UK - and perhaps Europe - is the Fortingall Yew. Estimates of its age range from 2,000 to 5,000 years, but Alison also visits a tree fossil on Mull which is 60 million years old! Reelig Glen is home to many record-breaking tall trees including the tallest larch, the tallest lime and a contender for the tallest tree in Britain – a Douglas Fir.

Alison also finds out about the folklore associated with various native species, about the study of tree rings and what it can tell us about our past, and about the role forestry has to play in Scotland’s environment and economy.
