Ecological Survey 1999
Spring, Summer & Autumn Cut
(Section 6)
Summary
 |
This section
contained the most plant species of any of the sections and although it was dominated by
the grasses, Yorkshire Fog and Common Bent, these were intermingled with a great variety
of wild flowers and mosses at ground level. |
 |
The section
was very diverse over much of its area and each quadrat normally contained a considerable
number of different species. Included
amongst the wildflowers were Greater Bird's-foot Trefoil, as well as several species more
characteristic of heathland habitats, such as Heath Speedwell (light blue flower spikes on the left) and Tormentil. |
 |
The composite
flowering plant family was well represented in this section, with several perennial and
biennial species commonly found across much of the area. These included Cat's-ear (yellow
flowers on the left), Autumn Hawkbit, Marsh Thistle
and some Ragwort. These grew interspersed among the dominant grasses. |
 |
The
section also contained considerable quantities of the creeping herb, Bugle (blue flower spikes on the left) together with Woodrushes (also
visible flowering on the left).
These plants flower in the spring and have died back
considerably by the time of the annual survey in July. As a result, their dominance
is not truly reflected in the survey data.
This section contained fewer tree seedlings
than other sections, although a non-native cherry seedling is visible in the foreground (left) |
| Heather,
although not widespread, occurred in several large, extremely dense clumps. A few isolated
plants of Bell Heather were also present. There
was little Bramble or Silver Birch in this section. |

| Percentage
frequency = the percentage of the total number of quadrats sampled over the whole site
which contain the species. For example, a percentage frequency of 100%, means that the
species was found in all quadrats sampled. |
Summary:
- The dominant plants in this section were the grasses
Yorkshire Fog and Common Bent.
- The section resembled a wild flower meadow habitat,
although it also contained a number of characteristic heathland species such as Heather,
Bell Heather, Tormentil and Heath Speedwell.
- The Heather in this section had become extremely
thick from the frequent cutting. As a result, even though it was low-growing, no other
plants could become established in amongst its dense, woody growth.
- The section was extremely diverse over much of its
area. The regular cutting throughout the year prevented any one plant from becoming too
tall and shading out the other smaller plants.
Changes since the previous year:
- Violets approximately doubled in abundance, becoming
the third most dominant plant in this section.
- The amount of Heath Speedwell, Heather and European
Gorse had approximately doubled in this section since the preceding year.
- Pill Sedge, while not present in extensive quantities
increased ten-fold.
- Moss cover also increased, with the amount of Eurhynchium praelongum
and Thuidium tamarascinum increasing at least three-fold.
