The Lambourn is an example of sub-type 1 in central southern England, a chalk stream discharging into the middle reaches of the Thames system. For part of its length it is a winterbourne, drying through the summer months. It is one of the least-modified rivers of this type, with a characteristic flora dominated by pond water-crowfoot Ranunculus peltatus. In the downstream perennial sections R. peltatus is replaced by stream water-crowfoot R. penicillatus var. pseudofluitans.
