Skiddaw Group SSSI is a site of special scientific interest in the Lake District High Fells, England. Its shape is approximately a rough circle centred near Great Calva, with an area of {{convert|10,256.3|ha|sqmi}}.{{cite web|url=https://designatedsites.naturalengland.org.uk/SiteDetail.aspx?SiteCode=s1002461|title=Skiddaw Group SSSI detail|website=Natural England|series=Designated sites|accessdate=11 May 2025}} The high ground creates a watershed between the Caldew Operational Catchment with water flowing north towards Carlisle, and the Ellen and West Coast and Derwent Operational Catchments flowing towards the west coast at Workington and Maryport.{{cite web|url=https://environment.data.gov.uk/catchment-planning/ManagementCatchment/3028|title=Derwent North West Management Catchment|publisher=Environment Agency|website=Catchment Data Explorer|accessdate=11 May 2025}}{{cite web|url=https://environment.data.gov.uk/catchment-planning/OperationalCatchment/3063|title=Caldew Operational Catchment|publisher=Environment Agency|website=Catchment Data Explorer|accessdate=11 May 2025}}
The SSSI is designated for its flora and fauna, and for its geology. The geology includes the Skiddaw Group of sedimentary rock formations, and the Caldbeck Fells former mining area. Fells above {{convert|2000|ft|m}} include High Pike, Carrock Fell, Knott, Great Calva, and Bowscale Fell. The highest peaks are in the Skiddaw area, including Skiddaw itself, Long Side, Carl Side, Little Man, Lonscale Fell and, further east, Blencathra.
The SSSI is divided into "units" which are used as the level of geographic detail for reporting overall features and conditions.{{cite web|url=https://england-peat-map-portal-ncea.hub.arcgis.com|title=England Peat Map Portal|publisher=DEFRA|accessdate=1 June 2025}} Each unit is identified by the Ordnance Survey grid reference at the centre of the unit, its area in hectares, the date it was last surveyed, and the drainage catchment it is located in.{{efn|Units are not catchment-based. The unit boundaries do not precisely follow catchment boundaries so the catchment name associated with the unit is indicative only.}} For example Bassenthwaite Common, which is unit 27, is nearly {{cvt|700|ha|sqmi}} centred at {{Ordnance Survey coordinates|NY252299}} in the Dash beck catchment. The habitat is there is dwarf shrub heath which, when surveyed in November 2010, was in an "unfavourable – recovering" condition.
Skiddaw Forest
Skiddaw Forest is the ancient name of an expanse of land to the east of Skiddaw summit, with the word "forest" referring here to a medieval pattern of land ownership.{{cite book|first=Angus|last=Winchester|title=The Harvest of the Hills: Rural Life in Northern England and the Scottish Borders, 1400-1700|publisher=Keele University Press|date=2000|isbn=978-1853312397|pages=10,14|quote=[Forests here were] the upland portions of great baronial estates anchored in the surrounding lowlands, a relationship seen particularly clearly in the Lake District.

Caldbeck Fells mines
{{See also|German mines at Caldbeck}}
The SSSI designation includes a number of sites of former mines, noted today for the presence of minerals in spoil heaps and erosion sites.
Spoil heaps at Red Gill Mine ({{Ordnance Survey coordinates|NY295347}}) include rare, crystallised lead sulphates, carbonates and phosphates. An adjacent mine at Roughtongill ({{Ordnance Survey coordinates|NY302344}}) reveals supergene minerals including copper and zinc varieties. English Heritage undertook a detailed survey of Roughtongill in 2001 and reported on its history and archaeology.{{cite journal|title=Roughton Gill Mine and Silver Gill Mine, Cumbria|first1=Marcus| last1=Jecock|first2=Christopher|last2=Dunn|first3=Amy|last3=Lax|journal=Archaeological Investigation report|issn=1478-7008|orig-date=2001|date= 24 June 2016|url=https://historicengland.org.uk/research/results/reports/123-2001}}
Dry Gill Lead Mine ({{Ordnance Survey coordinates|NY324345}}) has a unique form of mimetite, known as 'campylite'. Natural England surveyed the site (SSSI Unit 10) in 2022 and found the exposed mineral veins had been damaged by collectors in the past but not recently. Burdell Gill ({{Ordnance Survey coordinates|NY307324}}) "is of national importance as the only relatively abundant source of the rare arsenic mineral, pharmacosiderite, in Britain." A vein at Wet Swine Gill ({{Ordnance Survey coordinates|NY314321}}) includes stibnite and fuloppite but the 2022 survey (SSSI Unit 2) found that geological specimen collecting continued to cause damage. In the Carrock Mine – Brandy Gill spoil heaps ({{Ordnance Survey coordinates|NY322338}}) the mineralisation is tungsten-rich.

Caldew operational catchment
File:House at the foot of Carrock Fell - geograph.org.uk - 5163753.jpg
The Skiddaw Group SSSI includes the headwaters of the Whelpo (Cald) Beck and Caldew (upper) 'water bodies' (catchments). These are part of the Caldew operational catchment.{{efn|name=jargon|Natural England groups catchments ('Water Bodies') into 'operational catchments'. Those are grouped into 'management catchments', which are grouped into 'river basin districts'.}}
The Whelpo Beck catchment includes Brae Fell ({{cvt|586|m|ft}}), and the former mine sites at Red Gill and Roughtongill. When surveyed by Natural England in 2010, both mine sites (SSSI Units 3 and 11) were showing some signs of collector activity and erosion but were not considered to be under threat. The "dwarf shrub heath" habitats were surveyed in 2022 (SSSI Units 23 – Roughton Gill; 25 – Caldbeck North; and 26 – Brae Fell). They were all depleted by heavy grazing. Patches of bilberry were observed on Brae Fell.
The Caldew (upper) catchment accounts for 40% of the total area of the SSSI and the majority of its assessment units. The River Caldew flows there between the Blencathra uplands in the south-east of the SSSI, and the Skiddaw and Caldbeck Fells uplands to the west and north. The catchment includes Great Calva ({{cvt|690|m|ft}}) and Carrock Fell ({{cvt|661|m|ft}}). Around the edge of the catchment, Lonscale Fell, Skiddaw, Skiddaw Little Man, and Bowscale Fell form watersheds with the catchments in the Derwent Operational Catchment area. It includes the former mine sites at Dry Gill Mine, Carrock Mine-Brandy Gill, Burdell Gill and Wet Swine Gill. It also includes Bowscale Tarn ({{Ordnance Survey coordinates|NY336313}}), one of two glacial tarns in the SSSI, where quillwort isoetes lacustris, shoreweed littorella uniflora and water lobelia lobelia dortmanna have been found.
Heather moor predominates on sloping ground north and west of the River Caldew across several catchments. The east-facing slopes of Skiddaw, Little Man and Jenkin Hill exhibit degraded moss heath. Juniperus communis scrub, which is a nationally rare habitat, is most extensive on the steep, rocky south-facing slopes of Carrock Fell ({{Ordnance Survey coordinates|NY342336}}).
Derwent management catchment
The Skiddaw Group SSSI includes headwaters of the Derwent management catchment,{{efn|name=jargon}} consisting of the Ellen (upper) catchment, which flows towards Maryport, and a number of catchments flowing towards Workington:
- Dash Beck
- Derwent US Bassenthwaite Lake and Derwent DS Bassenthwaite{{efn|In these catchment names, US and u/s mean "upstream of"; DS is "downstream of"}}
- Glenderaterra Beck
- Glenderamackin u/s Troutbeck and Glenderamackin (Greta)
The Ellen (upper) catchment is at the north of the SSSI in the Uldale Fells. It is bounded by Longlands Fell, Lowthwaite Fell, Little and Great Sca Fells, Meal Fell and Great Cockup. Great Cockup ({{Ordnance Survey coordinates|NY270334}}) is known for fossils of dendroid graptolites. Tremadoc–Llanvirn geology is visible in the crags around Great Cockup. The heathland lacks species diversity and shows signs of heavy grazing. For catchment management purposes, the main water body is the Dale Gill which rises between Great and Little Cockup. The River Ellen's headwaters, with numerous small tributaries, drain the Uldale Fells and join Dale Gill beyond the SSSI boundary.
file:Whitewater Dash - geograph.org.uk - 2137126.jpgThe SSSI includes the headwaters of the Dash Beck catchment, including short lengths of Dash Beck itself, and of a number of its tributaries. The part of the catchment within the SSSI stretches from Great Sca Fell in the north-east to Ullock Pike {{cvt|7|km|miles}} away in the south-west, with the Whitewater Dash waterfall ({{Ordnance Survey coordinates|NY272313}}) where the beck crosses the catchment midway between the two.{{cite web|url=https://environment.data.gov.uk/catchment-planning/WaterBody/GB112075070530|title=Dash Beck Water Body|website=Catchment Data Explorer|publisher=Environment Agency|accessdate=13 May 2025}} The area includes Bakestall where empetrum nigrum is the dominant dwarf-shrub. It also includes Broad End which has "the best developed example [of montane moss-grass heath in West Cumbria] at about {{cvt|700| m|ft}}" elevation. There are two monitoring units in the Dash beck catchment: Uldale South (SSSI Unit 19, {{Ordnance Survey coordinates|NY282322}}) has low species diversity with some areas recovering; Uldale North (SSSI Unit 18, {{Ordnance Survey coordinates|NY272342}}) includes calluna vulgaris, vaccinium spp, empetrum nigrum and erica tetralix but the sites are fragmented where they should be continuous. In the north-east of the catchment, the watershed is marked by Knott, Great Sca Fell, Meal Fell, and Great Cockup.
The Glenderaterra Beck catchment includes Lonscale Fell (SSSI Unit 29, {{Ordnance Survey coordinates|NY289269}}, surveyed 2024) and Blencathra North West (SSSI Unit 32, {{Ordnance Survey coordinates|NY311274}}, surveyed 2019). Lonscale Fell ecology included some bracken and limited cover of ericoid shrubs in its "acidic grassland with bilberry" habitats. Blencathra North West had "blanket bog with abundant hare's-tail cotton grass and deer grass over locally abundant bog mosses".
There is a small area of Juniperus communis scrub in Glenderamackin u/s Troutbeck on The Tongue ({{Ordnance Survey coordinates|NY347302}}). The same catchment includes Scales Tarn (Blencathra), one of the two glacial tarns in the SSSI. The tarn has "low nutrient levels and [is] inherently species-poor." The area around the tarn has in the past been subject to heavy grazing. Mungrisdale East (SSSI Unit 35, {{Ordnance Survey coordinates|NY343297}}) includes hare's-tail cottongrass, abundant sphagnum and a good population of serrated wintergreen. Young Wood (SSSI Unit 38, {{Ordnance Survey coordinates|NY350307}}) is protected by fencing to keep grazing animals away and the oak woodland is recovering.{{cite book|last1=Wallace|first1=Carrie|last2=Atkins|first2=Roger|date=2013|chapter=Young Wood: a woodland beyond the edge|editor1-last=Rotherham|editor1-first=Ian D.|editor2-last=Handley|editor2-first=Christine|editor3-last=Agnoletti|editor3-first=Mauro|editor4-last=Samojlik|editor4-first=Tomasz|title=Trees beyond the wood: an exploration of concepts of woods, forests and trees|publisher=Wildtrack Publishing|location=Sheffield, UK|pages=311-332|chapter-url=https://insight.cumbria.ac.uk/id/eprint/1522/1/Weatherall_YoungWood.pdf}}{{cite web|url=https://jerramecology.co.uk/wp-content/uploads/MungrisdaleSaddlebackBowscalellFellCommons-Fencing-Consultation-Summary-Sept2023-1.pdf|title=Mungrisdale, Saddleback and Bowscale Fell Commons (CL293, 66 & 60) Woodland Exclosure Permission Renewal Summary|first=Rigby |last=Jerram|date=11 September 2023|accessdate=22 May 2025}}

For example SSSI Unit 22 "Carrock Fell" includes an area of "moorland, heathland and montaine" habitat which would benefit from enhancement. However the south west edge of the unit is in worse condition so would need restoration.
