Excursion reports 2019
|
6 excursions were organised in 2019, the majority to proposed Local Biodiversity Sites (pLBS) and one to a Site of Special Scientific Interest (SSSI).
39 different individuals attended the outings, collectively contributing 53 field work days to TWIC. In total, 1,765 species records were submitted to
TWIC from the excursions. Thank you to everyone who attended, especially the following who led outings for TWIC in 2019: Douglas McKean,
Katty Baird and Michael Scott. Thanks also to the landowners and land managers who gave us permission to access their sites. Data from the TWIC excursions
can be viewed on the NBN Atlas Scotland.

Straiton Pond - Midlothian, Sat 18 May 2019 (NT282667)
This was a joint meeting with the Edinburgh Natural History Society (ENHS).
- Leaders
- Douglas McKean and Natalie Harmsworth
- Number of species records
- 300
- Groups recorded
- Vascular plants, birds, fungi, insects - alderflies (Megaloptera), beetles (Coleoptera), hymenopteran & true flies (Diptera) -
lichens, molluscs, mosses and terrestrial mammals.
- Highlights
- Lothian Locally Rare plants included: Water-plantain (Alisma plantago-aquatica), Mare's-tail (Hippuris vulgaris), Knotted Pearlwort (Sagina nodosa) and White Campion (Silene latifolia). We also noted the neophyte,
Star-of-Bethlehem (Ornithogalum angustifolium) on site. A neophyte means "recent introduction" and is defined as any naturalised plant that was introduced to the UK after 1500. 25 bird species were recorded.
Ash Dieback (Hymenoscyphus fraxineus) was a less welcome sighting.

Broomridge - Stirling, Sat 1 June 2019 (NS801915)
- Leader
- Natalie Harmsworth (TWIC)
- Number of species records
- 282
- Groups recorded
- Vascular plants, birds, acarine (Acari), fungi, insects - beetles (Coleoptera), butterflies and hymenopteran - mosses and terrestrial mammals.
- Highlights
- No especially notable plant species were found, but the variety of habitats on site produced a list of 144 vascular plant species. Lowlights were the presence of several invasive non-native plants - Giant Hogweed (Heracleum mantegazzianum),
Japanese Knotweed (Fallopia japonica) and Indian Balsam (Impatiens glandulifera). Crocosmia which has been planted to beautify the verge also appeared to be invading damp grassland where Common Spotted-orchids (Dactylorhiza fuchsii) grow.
