Higher Plants Epping Forest as a wood-pasture system has a rich mosaic of habitats in a relatively small area. Woodland, grassland, heathland and aquatic habitats are the major types present. However, all these habitats grade into each other, the interface between the different habitats providing for a rich variety of plant species. The most profound influence on the flora is the Forest's wood-pasture history. The cutting of the trees for wood and the grazing and browsing of livestock over many centuries is the reason for the presence or absence of many plant species. Grazing has been most important in allowing the continued existence of many plant species that would otherwise have been ousted by competition from more vigorous plants, trees and shrubs and also eliminating other species susceptible to grazing pressure. For the purposes of this book. I have divided this chapter into four sections, each of which deals with a brief, historical review of the habitat (or sub-habitat) involved, a discussion of the plant species found there and in some cases I have included a list of plants from a recently surveyed site, to give an indication of those species that can be found in the Forest today. In the text I have included many historical records. Most of these are located to specific sites within the Forest. This account deals with the physical Forest, but it must be remembered that, in the past, areas have been lost to enclosures and yet other areas added to the Conservators' jurisdiction, which were formerly not considered part of the physical Forest (i.e. ground where commoners' beasts were not permitted to graze). 1) Woodland: Ancient Woodland Pollarded Woodland Coppiced Woodland Native Trees and Shrubs Notable Forest Trees Secondary Woodland Introduced and Planted Trees and Shrubs 2) Grassland and Heathland: Neutral Grassland Acid Grassland, Grass Heath, Wet Heath and Bog 3) Aquatic: Marsh, Pond and Streamside 4) Miscellaneous: Enclosures Green Lanes Roadside Verges Disturbed Ground Introduced Plants 1) Woodland Ancient Woodland: Pollarded A review of the history of pollarding is to be found on pages 18 to 26. (Tables referred to in the text are located on pages 81 to 85) A visit to formerly pollarded woodland in Epping Forest today, reveals in most places, a dense interlocking canopy of Beech trees on sites where the underlying geology is gravel, or of Oak and Hornbeam where the geology is clay. Beneath the pollard trees there can be virtually no vegetation, just a thick layer of partly decomposed leaves under the Beeches, and Holly bushes, some now of a substantial size beneath the Oaks and Hornbeams, and less often under Beech. To the botanist, this presents a rather species-poor picture. This, however, has not always been the case. Up to the mid- 19th century when the Forest was managed as a wood-pasture, the cyclical cutting of the pollard trees allowed light to reach the ground and this in turn would have allowed the growth of herbaceous plants. Sadly no-one recorded the species of plants found in areas of recently pollarded woodland in the Forest in the 19th century. The best we can probably do is to look at areas where, by accident or design, old pollard woodland has been felled, for example after the drought year of 1976. Lords Bushes, an 55
