The roadside verges and their vegetation in selected counties of north England were evaluated for their conservation status. Thirty five different road sections each 50 m long along different A and B class roads were surveyed and the criteria selected for conservation evaluation included verge area, plant diversity, species richness, disturbance, presence of rare species and structure of hedges. A field assessment sheet was prepared in which, for each factor, a numerical rating system was used. For each factor, information was recorded to help the surveyor in choosing the appropriate score for that site. The rarity of recorded species was determined from the published sources. Most of the surveyed verges (54%) are of low conservation value, 40% are of medium conservation value and only 6% have high conservation status. Despite the unsatisfactory situation, there is considerable potential for using roadside verges for nature conservation because medium class verges could be improved by adopting sound management techniques.

Roadside verges have obtained an important status in modern landscapes for conservation biodiversity, and their soils play a significant role in this regard. In designing more appropriate strategies for the integrated management of roadside habitats for nature conservation, the knowledge of physico-chemical characteristics of their associated soils is a prerequisite. The fertility of roadside soils in northern England was determined both by phytometric assessment using tomato plant and by chemical analyses of nitrogen, potassium, and phosphate levels. By comparing levels of these nutrients with their published normal levels, it was found that these soils have sub-optimum to optimum levels of fertility. The results of phytometric assessment revealed that the soils have low to medium levels of fertility. The fertility exhibited a pattern of zonation in the roadside soils with an increase with increasing distance from paved roads. Three nutrients were correlated with phytometirc assessments, and it was found that only nitrogen had a significant correlation with results of phytometric assessment.
