Alder: good survivor

Alder which is one of our most widely distributed native trees flowers before the leaves come out and has attractive reddish catkins and small ‘cones' that contain seeds. Alder will grow on most soils but prefers wet soils. It thrives in damp areas, beside lakes and rivers where its strong fibrous roots protect the river banks thereby reducing erosion. Given a rich damp soil alder will grow rapidly and is a productive timber tree. A unique feature of alder is its root nodes which can fix nitrogen thus enabling it to survive on infertile soils.

More money than sense

The Celtic Tiger boom has seen an explosion in the sale of art as Irish people have become gripLast year a Louis le Brocquy watercolour sold at a Sotheby's auction in London for the equivalent of €230,000 – ten times more than expected and far more than many deemed it to be worth.

Father of forestry

Augustine Henry (1857 – 1930), Ireland's greatest plant collector and botanical explorer, was born 150 years ago on the 2 of July 1857. Even though he was the archetypal absent-minded professor, he advanced through three brilliant careers, and made massive achievements in each. After hearing a recruitment speech delivered by Sir Robert Hart, in Belfast in 1879, he was inspired to travel to China. He trained as a physician, and was to spend 18 years working for the Imperial Chinese Customs Service, from 1881 to 1899.

Walks: Prague, Czech Republic

Walking is the way to see Prague as motor traffic is banned in the city's historic areas: the old and new town, Jewish Quarter and, across the river Vltava, the castle and little quarter. Start at the Old Town Square, one of Europe's finest public spaces. Windows on the medieval clock open and Biblical figures move around as the clock chimes hourly.

One of our smallest aquatic birds, at just 26cm in length, it is dwarfed by ducks, Moorhens, Coots and other water birds.

Hamas and Fatah: a history of conflict

The differences between Hamas and Fatah lie in their respective visions for a Palestinian future and the methods employed to achieve these ends. Since its foundation following the first intifada against Israel's occupation of Palestinian land in 1987, Hamas has seen Fatah's two-state solution as implicit recognition of Israel. Instead, Hamas wants to establish an Islamic state on all of historic Palestine – much of which lies within Israel's present borders.
