Yorkshire fog a very widespread and versatile grass able to exploit widely different soil conditions and management practices. It may, however, be limited by grazing or heavy trampling. It is most frequent on relatively fertile soils (pH 5.0–6.0) and is more abundant on moist rather than waterlogged soils, although it can survive in anaerobic conditions. Cocksfoot, another widespread grass, tolerates summer grazing but fares better where grazing is infrequent. It is usually considered to be susceptible to trampling but survives light burning.
