Earliest Cairngorms fixed point photo (21 December 2000):

Photos are taken looking up the catchment of the Allt a 'Mharcaidh. When we first began recording this view the summit of Geall Carn (920 m) was visible on the right and, in the centre, the highest summit, Sgoran Dubh Mor (1111 m). These summits are often obscured by cloud. Tree colonisation due to reduced levels of deer grazing is an important feature of the site and mature trees now almost completely obscure the view of the surrounding mountains. The ECN Target Sampling Site (TSS) is on the ridge to the left of the photograph, at 700 m.

Earliest Moor House fixed point photo (24 September 1997):

This is a view over the Trout Beck towards Great Dun Fell and Cross Fell. The view is westward from a point (Grid Ref NY756334, Altitude 540 m) overlooking the Trout Beck at its junction with Nether Hearth Sike. In the middle distance is Shaft Hill (0.5 km away) where many of the ECN terrestrial measurements are made. The vegetation is dominated by ling heather (Calluna vulgaris), cotton grass (Eriophorum spp.) and Sphagnum moss, on blanket peat up to 3 m thick. On a clear day three distant hill tops are visible. To the left of Shaft Hill is Great Dun Fell (847 m altitude, 4.8 km away) which has a radar station at its summit. This is the highest point on the reserve and the second highest point in the Pennines. In the centre of the picture and only just protruding above Shaft Hill is the flat top of Little Dun Fell (842 m altitude, 5.2 km away). To the right is Cross Fell (893 m altitude, 7.0 km away) which is outside the reserve and is the highest point in the Pennines. The Pennine Way Long Distance Trail passes over these three summits.

Earliest Rothamsted fixed point photo (16 January 2004):

At Rothamsted the majority of the ECN protocols are centred on the Park Grass long-term grassland experiment with its history of botanical and ecological monitoring going back over 150 years (est. 1856). The photograph is looking across Plot 3, Section d (foreground) of Park Grass. This plot is of interest to the ECN as it receives nil applications apart from those coming from the atmosphere. As you look further towards the background sections c, b, and a have received differing rates of agricultural lime (chalk) and have different plant communities from that of Plot 3, section d.

Earliest Wytham fixed point photo (25 February 1998):

The photograph is taken within the ECN Target Sampling Site (TSS) located on the northern side of Wytham Wood (U.K. National Grid Reference SP45 09, altitude 65m). The TSS is located in an area of ancient woodland (believed to have never been cleared) with abandoned hazel (Corylus avellana) coppice with oak (Quercus robur) standards (full height trees).  The soil is a deep heavy clay (Denchworth series) which is often waterlogged in winter. The photograph shows the multi-stemmed hazel stools with an oak standard on the left-hand side. To the left of centre there is a willow (Salix caprea) leaning across the picture, with a small hawthorn (Crataegus monogyna) tree behind it. The grass is mainly Tufted hair-grass (Deschampsia cespitosa) with some Wood false-brome (Brachypodium sylvaticum). The dead wood is left where it falls.
