Liverworts and Mosses of Southern Epping Forest

My expertise in readily and reliably identifying the bryophyte flora has been limited, so in the tables below only a representation of some of the species that may be present in the area is given. Photographs where available may be viewed by clicking on the scientific name. Initials in brackets after location relate to recorder. Thanks to Roger Snook for additional information about some of the species, and his notes on where some species may be found are given as (RS) in the locations column. Additionally, a visit by Ken Adams (KJA) on 23 February 2015 added more species to the list.

Epping Forest as a whole has a wide variety of semi-natural habitats and it is said that the Forest supports an outstanding bryophyte flora, with 177 species in evidence. (source: English Nature)  The same article states that the Forest's bryophytes have declined in variety as a result of problems including shading, scrub on the heaths, human interference and atmospheric pollution. Our area too - which includes Wanstead Flats, Wanstead Park and Bush Wood - is quite varied in habitat, but probably all of those problems exist in this part of the Forest. Indeed, Roger Snook laments the loss of some of the ditches and wet flushes, particularly north of the fairground site on Wanstead Flats, which only a few years ago held a much greater number of bryophytes, both in quantity and species.
