The Effects of Fencing on Natural Regeneration of Native Pinewood after Six Years in Coille Ruigh na Cuileige, Glen Affric

In 1996, Clare Cummings, carried out a follow-up study to the research done by Paul Blanchflower in 1990 on the occurence of naturally-regenerating Scots pine seedlings at Coille Ruigh na Cuileige in Glen Affric.

Here is the summary of Clare's work, from her survey report:

Summary

Prior to the erection of a stockproof fence, a grid of 38 permanent plots was laid out by P. Blanchflower (in 1990) to provide baseline data to monitor the effects of stock exclusion on natural regeneration of Scots pine. The present survey collected data from the original plots (of which 31 were found) recording for each plot: the number of seedlings; seedling height; seedling diameter; height of the surrounding vegetation; diameter distance and orientation from the plot centre of the possible seed source.

All measurements were averaged. Data from 1990 and 1996 was compared and frequency tables comprised and graphed.

The average number of germinating seedlings per plot increased by 5.54 (11.97%). The average height of seedlings was 21.5 cm, compared with 8.5 cm in 1990, an increase of 13 cm (152%) the average diameter of seedlings increased by 2.74 mm (74%).
