Construction of a second runway at Manchester Airport led to a £17 million environmental
mitigation package concerned with habitat restoration, relocation of species and translocation
of valuable habitat components. One major concern was for legally protected vertebrate species
(Meles meles and Triturus cristatus) affected by these works. To this end, a monitoring programme
was established to assess earthworm communities (potential prey for the protected animals)
within areas of translocated grassland. Major upheaval of soils can have negative consequences
on soil biota, so integration of translocated turf with receptor subsoil was essential. Early results
(Butt et al, 2003) suggested that numbers and masses of earthworm communities had either
increased or remained relatively stable four years after grassland translocation.
The work reported here relates to continued monitoring of 4 specific translocated grassland
areas. Digging and hand sorting of soil from replicated plots of 0.1m2, followed by vermifuge
(mustard) application was used to extract earthworm specimens. Monitoring took place on an
annual basis during the same week of October.
From 1998-2007, twelve species of earthworm have been located, representing epigeic,
endogeic and anecic groups. Numbers have fluctuated during this period. Lowest recorded
density was 4 worms/m2 and highest was more than 100 times larger. Similarly, biomasses
have ranged between 1g and 110g/m2. Significant differences can be accounted for through a
number of factors including type of translocation undertaken (turf transfer or soil alone) and also
between grassland sites (low lying, slopes, hillocks) and across years. Meteorological data
suggests that the most significant environmental aspect during the decade of monitoring was
rainfall, having its greatest negative effect on earthworms in 2003, a year with a particularly dry
summer. Earthworm community composition, like population sizes has been dynamic over this
time period. Further monitoring of earthworm communities at Runway 2 will continue until at
least 2012. MenosConstruction of a second runway at Manchester Airport led to a £17 million environmental
