Jarvis Brook

Jarvis Brook was not mentioned in the Domesday Book from 1068,^[5] but is mentioned in a custumal from 1346, being spelt as "Gervys Brook".^[6] The spelling may have been influenced by Priscilla Jarvis of Mayfield, who owned land in the village. The earliest record of the village on a map is one from 1789.^[7]

The village grew when the station opened, with factories and houses being built around the area. The Crowborough Country Park was a clay quarry that supplied the Crowborough brickworks that opened in 1879^[8] until it closed in 1980.^[9] In 2009, it was turned into a local nature reserve.^[10]

A church school was built on the site of St Michael and All Angels church in 1882 on land lent by Lord Abergavenny, with the church following suite in 1902. The church became its own parish in 1934.^[11]

The Jarvis Brook Memorial Hall is a hall that was constructed and given to the people by wealthy landowners around the 1920s^[12] and has been used for various purposes, including a World War 2 hospital,^[12] where it got its namesake. In more recent times, the hall has fallen into a state of disrepair, with funding needed for the roof.^[13]

The village gets an hourly service from Crowborough railway station,^[14] and an infrequent local bus around the village and to Crowborough nearby.^[15] Two bus lines operated by Wealdlink serve the village, one heading to Wadhurst^[16] and the other heading down to Battle.^[17]

The B2157 runs along the north of the village and terminates at the B2100,^[18] which cuts straight through the village and heads down to Lamberhurst.^[19]

The Jarvis Brook is a small river that flows from several tributaries around Crowborough and is part of the Medway Upper catchment area.^[20] The river feeds into the Eridge Stream.

Along the river was Maynards Gate Furnace, a blast iron furnace. It was working in 1653 but ruined by 1664.^[21][22] It served the Maynards Gate Forge, which shared the same pond as the Furnace. The only modern evidence of its existence is the sudden ending of leat in a leveled area along the river downstream.^[21]

The Environment Agency measures the water quality of the river systems in England. Each is given an overall ecological status, which may be one of five levels: high, good, moderate, poor and bad. There are several components that are used to determine this, including biological status, which looks at the quantity and varieties of invertebrates, angiosperms and fish. Chemical status, which compares the concentrations of various chemicals against known safe concentrations, is rated good or fail.^[23]

The water quality of the Jarvis Brook is as follows:
