The following observations result from
an inspection of the plant species list of the Wet
Woodland.
There are 70 recorded plant species present across the
Wet Woodland Area. Of these, 14 species are mosses, representing 20% of the
total. This is a significant amount indicating that mosses are an important
component of ground vegetation within the Wet Woodland. Some of the mosses are
widespread across the Wet Woodland indicating they are tolerant of a variety of conditions
including level of moisture. Some of these mosses are Polytrichum formosum,
Leucobryum glaucum, Mnium hornum, Thuidium tamariscinum, Hypnum cupressiforme and Hypnum
andoi. Other moss species were confined to certain areas indicating they can
only grow where the conditions are favourable. These included:-
Eurhynchium praelongum -
found only in the Cherry Area.
Campylopus introflexus (which favours dry areas) - found in the
Stony Area & the Clearing - these are both fairly dry.
Sphagnum sp. (grows only in moist areas) - found only in the
Seepage Area, which is very wet.
Hypnum jutlandicum (normally a heathland species) - found in the
Stony Area and Bluebell Area. The fact that this species is present in the Wet
Woodland may indicate that the area was once lowland heath that has returned to
woodland. Hypnum jutlandicum is present in the Heathland which lies
adjacent to the Wet Woodland.
Tall trees were widespread across the Wet
Woodland. Silver Birch was the most common species and occurred in all six areas,
while Holly was also present in all six areas but only as very young trees. There
were no tall Holly trees in the Wet Woodland. Both Oak and Rowan were fairly
widespread while Hazel was specific to the Bluebell Area. Two other species, Red Oak
and Oregon Ash were scattered sparsely across a few areas of the Wet Woodland. Non-
native cherries occurred largely in the Southwest of the Wet Woodland adjacent to the
Heathland. They were found elsewhere in the Wet Woodland in smaller numbers.
Ferns were important across the Wet Woodland with Hard
Fern and Broad Buckler Fern being widespread. Bramble was also widespread, while
certain areas of the Wet Woodland contained species specific to certain conditions.
The Bluebell Area supported some shade tolerant plants such as Enchanter's Nightshade,
Wood Sorrel and Common Dog Violet, while the Seepage and adjacent parts of the Clearing
supported plants which were largely confined to damp conditions, including Wavy
Bittercress and many sedges and rushes. Indeed, Star Sedge is found nowhere else at
the Woodland Education Centre. Pill Sedge was the exception for the sedges, being
tolerant of drier conditions it was found on the Mound and in the Stony Area.
The presence of two species of heathers provided
evidence that the Wet Woodland was probably at one time lowland heath. Ling was
found in the drier areas of the Wet Woodland while the moisture-loving Cross-leaved Heath
was found in the Seepage. The Stony Area is quite dry and has many species which
also occur in the Heathland that lies adjacent to it. |
