Native Caledonian Pine,

Abernethy Forest, Cairngorms

This page last updated 07/05/06

Scots pine 'native' coniferous forests
  • Although we tend to think of the Scottish Highlands as open moorland it was once forested and the woodland resource is ecologically important (45% of the Cairngorm area is heather moorland and 17% is blanket bog).
  • The Cairngorms covers only 8% of Scotland's land mass, yet contains over a quarter of the native woodlands in Scotland.

Cairngorm landscapes by Dr Adrian Hall, has a page on late-glacial vegetation featuring pioneer species from 14,000 to 11,000 years ago (primary succession). A page on the Holocene covers the introduction of trees to the area 10,000 years ago and subsequent changes associated with a cooler and wetter climate around 6,000 to 5,000 years ago. http://www.fettes.com/Cairngorms/ Holocene vegetation Late glacial vegetation

Birds The native pine forest of Scotland is an important habitat for Ospreys (nesting), Capercaille and Scottish Crossbills.

Trees for Life species profiles

Podsol soil profile This type of soil is particularly associated with coniferous woodland vegetation at northern latitudes where the climate is typically cool and wet. Precipitation rates are greater than evapotranspiration, causing water to move downwards through the soil. The litter layer, dominated by waxy pine needles, decays very slowly. This causes a thick acid humus layer to form on the surface (mor humus). Rainwater passing through mor becomes highly acidic and able to chemically break down clay, iron and aluminium. Acid water moving down through the profile causes soluble bases to leach, clays to be moved and the washing out (eluviation) of iron and aluminium sesquioxides. The upper layers (A horizon) of the soil, depleted of these substances, becomes ash-grey - bleached of colour. Lower down the profile (B horizon) redeposition occurs. A thin layer of iron (an iron pan) may be found, followed by a dark humus layer and an orange-brown clay horizon. The layers are sharply defined partly because there is little earthworm activity (mixing).

Management

Cairngorms National Park 'opened' 2003. Although this is the biggest national park in Britain, it ended up covering half the area Scottish Natural Heritage recommended. The Scottish Executive have been criticised by campaigners who say political interests have been put before conservation.
