in the leaf litter and organic matter at the soil surface, rather than in the mineral soil. They feed on decaying leaf litter and are most common in woodlands, and are rarely found in golf courses. The most comprehensive research on earthworms on golf courses in the post-chlordane era was the work of Binns, Baker and Pierce, who investigated the factors influencing earthworm populations on fairways at thirty- two golf courses across the UK. Their research was published in the Journal of Turfgrass Science in 1999 (volume 75). Some of their key findings are summarised below. The average density of
earthworms on fairways was 45 per m2
The three commonest species collected were all surface casters: Aporrectodea longa and Lumbricus terrestris are both deep burrowers, while Aporrectodea caliginosa usually lives in the topsoil. The average number of surface casts was 42 per m2
highest number recorded was 119 per m2
Other species that sometimes occur in moderate to high densities on fairways are Aporrectodea rosea, Lumbricus rubellus and Allolobophora chlorotica, but these rarely cast on the surface, preferring to deposit their casts within the soil profile. The higher rates of casting occurred in areas with higher pH, higher moisture content and more vigorous grass growth.
any chemicals that are as effective, many turfgrass managers have adopted cultural control methods. Two management practices in particular can significantly reduce the amount of surface casting. The first is to reduce the
In the absence of chlordane, or . , although the recorded density was 170 per m2 , although the highest .
Discussions with turf managers, whose greens are infested, suggest chemicals used to reduce surface casting of native species have no effect on Microscolex phosphoreus, even when applied at the highest recommended concentrations.
In conjunction with Dr Kate Entwistle of the Turf Disease Centre, I am running a project to map the distribution of Microscolex phosphoreus. We need your help to discover
Microscolex phosphoreus is a non- native species that occurs in close- mown turf and casts on the surface. Since 2005, there have been confirmed records from at least fifteen localities in England, and many more unconfirmed sightings. It is a small earthworm, 10-35mm long and 1.0-1.5mm wide. It produces small sandy casts on the surface that can be 10-20mm in diameter, and up to about 15mm in height. Although the casts are relatively small compared with those of British species, they are still a problem because heavily infested areas have been reported to have as many as 340 casts per m2

earthworms’ food supply by removing grass clippings and any tree leaves. The second is to lower the pH of the soil with the application of acidifying fertiliser. Most species of earthworm will avoid acidic soils. However, the second method needs to be carefully monitored, as the quality of the turf is reduced if the soil becomes too acidic.
A new invasive earthworm
A new earthworm pest has recently arrived on British golf greens and bowling greens.
how far this species has spread across the country. If you have these small sandy casts on your greens, please send a turf sample to the address below. Use a hole changer to take a turf sample containing one or more casts, and send the top 5cm of the core with the grass and roots intact. Place the turf sample in a small plastic container that is strong enough not to get crushed in the post. Puncture small air holes in the top of the container. Ensure the sample is damp but not waterlogged. Loosely pack scrunched-up newspaper around the sample to prevent it being thrown about inside the container while in transit. Put the container in a padded jiffy bag and send by first class post.
information: your name, email address, name and address of the club where the sample is from, and date of sampling. The information you send will be treated as confidential. If you have any questions, please contact me by email on
dtj@nhm.ac.uk.
Send your turf sample to: Dr David T. Jones, Soil Biodiversity Lab, 7th floor, Darwin Centre 2, Natural History Museum, London SW7 5BD
