The Corona Australids are a meteor shower that takes place between 14 and 18 March each year, peaking around 16 March. This meteor shower does not have a high peak hourly rate. In 1953 and 1956, observers noted a maximum of 6 meteors per hour and 4 meteors per hour respectively; in 1955 the shower was "barely resolved". However, in 1992, astronomers detected a peak rate of 45 meteors per hour. The Corona Australids' rate varies from year to year. At only six days, the shower's duration is particularly short, and its meteoroids are small; the stream is devoid of large meteoroids. The Corona Australids were first seen with the unaided eye in 1935 and first observed with radar in 1955. Corona Australid meteors have an entry velocity of 45 kilometers per second. In 2006, a shower originating near Beta Coronae Australis was designated as the Beta Coronae Australids. They appear in May, the same month as a nearby shower known as the May Microscopids, but the two showers have different trajectories and are unlikely to be related.
There are several large and unique Sites of Special Scientific Interest (SSSI) around the village.
Cheddar Reservoir is a near-circular artificial reservoir operated by Bristol Water. Dating from the 1930s, it has a capacity of 135 million gallons (614,000 cubic metres). The reservoir is supplied with water taken from the Cheddar Yeo, which rises in Gough's Cave in Cheddar Gorge and is a tributary of the River Axe. The inlet grate for the 54-inch (1.4 m) water pipe that is used to transport the water can be seen next to the sensory garden in Cheddar Gorge. It has been designated as a Site of Special Scientific Interest (SSSI) due to its wintering waterfowl populations.
Cheddar Wood and the smaller Macall's Wood form a biological Site of Special Scientific Interest from what remains of the wood of the Bishops of Bath and Wells in the 13th century and of King Edmund the Magnificent's wood in the 10th. During the 19th century, its lower fringes were grubbed out to make strawberry fields. Most of these have been allowed to revert to woodland. The wood was coppiced until 1917. This site compromises a wide range of habitats which include ancient and secondary semi-natural broadleaved woodland, unimproved neutral grassland, and a complex mosaic of calcareous grassland and acidic dry dwarf-shrub heath. Cheddar Wood is one of only a few English stations for starved wood-sedge (Carex depauperata). Purple gromwell (Lithospermum purpurocaeruleum), a nationally rare plant, also grows in the wood. Butterflies include silver-washed fritillary (Argynnis paphia), dark green fritillary (Argynnis aglaja), pearl-bordered fritillary (Boloria euphrosyne), holly blue (Celastrina argiolus) and brown argus (Aricia agestis). The slug Arion fasciatus, which has a restricted distribution in the south of England, and the soldier beetle Cantharis fusca also occur.
By far the largest of the SSSIs is called Cheddar Complex and covers 441.3 hectares (1,090.5 acres) of the gorge, caves and the surrounding area. It is important because of both biological and geological features. It includes four SSSIs, formerly known as Cheddar Gorge SSSI, August Hole/Longwood Swallet SSSI, GB Cavern Charterhouse SSSI and Charterhouse on-Mendip SSSI. It is partly owned by the National Trust who acquired it in 1910 and partly managed by the Somerset Wildlife Trust.
