Botanical Recording in North-east Yorkshire in 2012
In 2012 there were 15,615 records added to the MapMate Database, giving a total of 279,273 records.
Work has continued on the Rare Plant Register. We view this as a continuing document which is updated every year. Its format is a list of records on a spreadsheet for each taxon separated (and colour-coded) into three categories:
- 1. records where the tetrad has not been revisited
- 2. recent (from 2007) records with full details, and
- 3. records where a tetrad/site has been revisited but the taxon not refound.
It was pleasing to find three new sites for Filago vulgaris (Common Cudweed), a species thought to be lost to the v.c. Carex muricata ssp. pairae (Prickly Sedge), always very rare within the v.c. was located in a second site recently – a moorland edge at Castleton. It was a good year for Willowherb hybrid finds – Epilobium hirsutum x E. parviflorum was discovered in four places and Epilobium tetragonum x E. obscurum, new to the vice-county, was on waste ground in Northallerton.
A belated start has been made on dock hybrids, three of which were new v.c. records – Rumex conglomeratus x R. sanguineus, Rumex obtusifolius x R. conglomeratus and Rumex obtusifolius x R. sanguineus.
Several aliens/garden escapes new to the v.c. were found; these included :- Conyza floribunda (Bilbao Fleabane) in three places in Teesside, in abundance at one site; Tanacetum macrophyllum (Rayed Tansy) at Husthwaite and Linaria maroccana (Annual Toadflax) at Northallerton. Vicia villosa (Fodder Vetch) near Cold Kirby and Saxifraga cymbalaria (Celandine Saxifrage) at Northallerton were both second v.c. records.
David Earl visited the v.c. and four new brambles were found – Rubus gratus, R. x pseudoidaeus (in two places), R. bartonii and R. intensior; the former pair east of York and the latter pair at Scarborough.
Four new dandelions were discovered – Taraxacum angulare, T. altissimus, T. anceps and T. scanicum; the latter very rare nationally.
We are grateful to D. Earl, G.D. Kitchener, A.J. Richards and M.J. Wilcox for checking specimens.
Botanical Recording in North-east Yorkshire in 2011
The total botanic records for v.c.62 in 2011 was just under 13,000 of which about 900 had 8-figure grid references.
There were three new native species for the vice-county: Gymnadenia borealis (Heath Fragrant-orchid) in small quantity in damp moorland near Rudland (G. conopsea sensu lato had been previously reported from the site); the rarely recorded hybrid Sweet-grass, Glyceria fluitans x G. declinata, with both parents in a ditch near Danby and the hybrid rush, Juncus xdiffusus = J. inflexus (Hard Rush) x J. effusus (Soft Rush), on the edge of Terrington Carr where both parents were common.
Aliens naturalised in the wild, new to the vice-county, included a good colony of Doronicum xexcelsum (Harpur Crewe’s Leopard’s-bane) well established on a rocky trackside bank behind the church at Gillmoor, a robust clump of Allium moly (Yellow Garlic) on the verge of the road over Harland Moor near Gillamoor and twelve self-sown plants of Pritzelago alpina on a stone wall by the Cleveland Way in Helmsley (may be a new British record).
Several casual self-sown garden escapes new for the vice-county were found. In particular, in gutters and pavement cracks were Rumex scutatus (French Sorrel) in Kirbymoorside, Achillea filipendulina (Fern-leaf Yarrow) in Crossgates near Scarborough and Lactuca sativa (Garden Lettuce) in Stokesley. Cosmos bipinnatus (Mexican Aster) occurred on waste ground at Stainsacre near Whitby.
It was particularly pleasing to re-find in the vice-county Fumaria purpurea (Purple Ramping-fumitory) on waste ground at Scalby near Scarborough (first record since 1917) and Fumaria vaillantii (Few-flowered Fumitory) on dumped soil on a building plot in Crossgates near Scarborough (first record since 1897 and may well be from the same site). Antennaria dioica (Mountain Everlasting), only the second recent record, was discovered in some abundance on the dry short calcareous turf above Stoney Gill Hole near Hawnby. Carex muricata ssp. pairae (Prickly Sedge), always rare in the vice-county, was found in some quantity on a road verge near Danby (first record since 1978). Centaurium pulchellum (Lesser Centaury) not seen for a few years at its only known site in the vice-county at the South Gare, was discovered at a new site at the South Gare. It was pleasing to note that Atriplex glabriuscula (Babbington’s Orache) has significantly extended its range and now is locally frequent at intervals between the South Gare and Saltburn.
Thanks are due to E. J. Clement, A. Copping and R.J. Murphy for checking specimens.
