A bryological tour through

Lincolnshire (v.-c.53 & 54)

... with Christine Rieser and Frank Lammiman

and a Postscript by Mark R D Seaward

 

The land of the Yellow Bellies (regimental colours I believe, not birds or beasts) is the largest English county after Yorkshire, and is often perceived as a vast, flat expanse of mainly cultivated and improved land subject to drying winds from the east and polluting winds from the west. The average bryologist would not be drawn to come here looking for rare mosses or liverworts but in fact there is a wide variety of habitats in the county, and careful and persistent search has revealed some interesting species.

The long coastline offers maritime marsh supported by scrub and sand dunes with a fresh water marsh behind, long stretches of this being SSSI/NNR of interest particularly to botanists and bird watchers.

In the south of the county, inland from the coast is a large area of reclaimed fenland which is of little interest to bryologists, but across North-East Lincs lie the low rolling hills of the chalk Wolds, mostly overlain with boulder clay. There are many abandoned chalk quarries here which are worth looking at, and woodlands to explore.

The more southerly area of the Wolds is on the Spilsby sandstone, which is not rich in bryophytes.

The clay valley to the West of the Wolds is in places overlain with acidic cover sands and elsewhere with more mildly acidic glacial sands and gravels as in the Woodhall Spa area, resulting in mildly acidic to mildly basic heathy areas.

The central clay area which is calcareous bears a group of woodlands known as the Bardney small-leafed lime woods.

To the west of the Ancholme valley there is a limestone ridge running from the South of the county in the Stamford area north to the Humber with two gaps at Ancaster and Lincoln filled by river gravel or sand. The Ironstone deposits mined for the Scunthorpe steel industry are associated with this ridge.

Beyond this to the west and north lie the Trent plain and the peat moors of the Isle of Axholme.

Major sites of interest for mosses and liverworts are as follows with some of the less common species found recently.

Postscript by Mark R.D.Seaward

The last published bryophyte flora for Lincolnshire was published 20 years ago (Seaward,M.R.D. 1983. A Bryophyte Check-list for Lincolnshire, Bradford). At that time, 382 taxa had been recorded from the county, of which 14 had not been seen since the 19th century (1 presumed extinct) and 18 were doubtful in the absence of supporting herbarium material. Since then, there has been a net gain of 15 taxa (some being lost due to taxonomic revision) and numerous taxa not seen for many years have been rediscovered, including several of those formally categorized as doubtful. By 2002 the Lincolnshire bryophyte flora could be summarized as follows:

 
Hepatics

Of those taxa not seen for 50 years or more, attention should be drawn to the nationally rare species, such as Bryum marratii and B.mamillatum, which were thought to have been swept away as a consequence of the disastrous coastal flooding in 1953. The very considerable coastal development, particularly in respect of tourism, since then would not be conducive to their continued presence or re-establishment, but one is always hopeful of rediscovering remnant populations in those dune systems embraced by nature reserves; the recent rediscovery of Bryum warneum there would support this view.

Due to a few devoted naturalists, bryological recording continues to thrive within the county, the results of which are published annually in the Transactions of the Lincolnshire Naturalists’ Union.
