Title

Aquatic macrophyte transect data for the River Lambourn at Boxford 2009 to 2014

Abstract

The dataset contains results from surveys recording the cover and area of aquatic macrophytes at four transects on the River Lambourn, collected monthly between March 11 2009 and September 30 2014. The River Lambourn is a tributary of the River Thames, the principal river in the south-east of England. The CEH River Lambourn Observatory comprises a 600 m reach of river and 24 acres of associated water meadows at Boxford, Berkshire. The surveys were designed to provide an estimate of the area and cover of the three most common aquatic macrophytes and an estimate of the area of the wetted channel at four transects. The species recorded were Ranunculus penicillatus ssp. pseudofluitans (with Ranunculus penicillatus ssp. pseudofluitans x Ranunculus peltatus hybrid also present), Callitriche platycarpa (with some Callitriche obtusanglia) and Berula erecta. The four transects were selected in order to represent a combination of shallow/fast flowing areas and deeper/slower flowing areas, as well as shaded and unshaded reaches.

Lineage

The surveys were designed to provide an estimate of the area and cover of the three most common aquatic macrophytes at four transects along the River Lambourn at Boxford. The species recorded were Ranunculus penicillatus ssp. pseudofluitans (with Ranunculus penicillatus ssp. pseudofluitans x Ranunculus peltatus hybrid also present), Callitriche platycarpa (with some Callitriche obtusanglia) and Berula erecta. The Ranunculus and Callitriche species were not identified to species level as this is frequently impossible without flowering material and because the study was more concerned with the quantitative characteristics of the aquatic macrophytes. The surveys were conducted monthly from March 2009 until October 2014 with one occurrence of missing data due to high flow which prevented accurate (and safe) surveying. When possible the surveys were timed to coincide with monthly hydraulic surveys reported elsewhere. The surveys were carried out at four transects distributed along the length of the CEH River Lambourn Observatory. These were selected in order to represent a combination of shallow/fast flowing areas and deeper/slower flowing areas, as well as shaded and unshaded reaches. At sites one to three the channel width is approximately 10m, but at the downstream site the width is nearer to 14m.
