About the reserve

The watercourse of Ewenni Fach runs through the area from east to west, and several smaller streams also run through the site from north to south, feeding down into the Ewenni Fach. The main line of the Great Western Railway forms the southern boundary of the site, and a disused railway line forms the northern boundary.

There are a number of public footpaths and bridleways on site, also two circular walks taking in the lovely mix of countryside.

The site is a haven for wildlife, notably the dormouse, populations have declined significantly as a result of changes in woodland management and over grazing of woodland leading to loss of food sources and fragmentation of habitats with gaps of 100m leading to colonies being prone to genetic isolation and extinction. Dormice, therefore are afforded strict legal protection through UK and European law. The dormouse is listed on schedule 5 of the Wildlife and Countryside Act 1981.

Coal mining in the Llanharan South area is recorded back to the 1870s. There is still evidence of this in Brynna Wood with shafts and mine adits still standing to this day.

These are excellent habitats for bats, The Llanharan area is of known significance for bats, with the nationally rare and declining lesser horseshoe bat and barbastelle bat both having been recorded in the area recently.

We have been lucky enough to work with film maker Robin Davies Rollinson to produce this lovely film about the reserve and the local community who have been so involved with its care and management over the last few years. This reserve has been created in partnership with the local Community Council and the local people of Llanharan and Brynna.
