IMG 2356 st marks cemetery highcliffe badger settWe found a badger sett in a cemetery in suburban Christchurch yesterday, most likely an outlier. It had only three semi-recently-used holes, and three shallow diggings. The nearest woodland which may support a main sett is around 500m away.

Thankfully the sett is in a bank rising up from the cemetery, and not in the ground where the graves are. Badgers are becoming much bolder inhabitants of suburbia these days, so it's always worth looking out for evidence, even in gardens.

In Southeast Dorset, we've recently found setts and other badger evidence in suburban gardens in Bournemouth, Christchurch and Ferndown.

Sett holes are a bit wider than fox holes, and often with a substantial amount of spoil outside them. They have a 'landscape' orientation, whereas fox and rabbit tend to dig holes in 'portrait'.

Badgers often nuzzle around in loose soil, looking for worms, and digging up bulbs. The resulting 'snuffle holes' are quite distinctive once you've got your eye in.

Badgers also tend to leave their dung in holes (dung-pits), usually on the edge of their territory, to ward off rival clans.

CGO Ecology offers all types of badger survey, and is experienced in sett closure under licence where badgers are disrupting property or causing other problems.

Winter is still survey season

The cold season means that many vertebrates, invertebrates and plants are in hibernation or some other form of dormancy; so it is usually a quieter time for professional ecologists. However, not everything stops for winter. We can still conduct a range of ecological surveys for a variety of purposes.


Snailing on Rùm

Tomorrow morning we're taking the CalMac ferry to the Scottish inner hebridean island of Rùm in search of rare snails. We're looking for tiny whorl snails (Vertigo species), guided by maps of Schoenus nigricans (black bog-rush, often associated with alkaline flushes), geology, geomorphology, and vegetation cover.


First sand lizard nests & a dash of heathland flowers

Late May is typically the time that sand lizards (Lacerta agilis) start digging tunnels in which to lay their eggs. First they make several exploratory diggings in bare firm sandy ground, and may take several attempts before they manage to dig a suitable egg burrow. The nesting period usually lasts from the last week of May to the first week of June in southern England, and activity may be peaked or spread over a wider period if weather is poor. Warm dry afternoons and evenings are the favoured time for digging.


Sand lizard capture & the equinoxes

As the days get shorter, this week in late September sees us pass the point of equal day and night length: the autumnal equinox. The spring and autumn equinoxes are busy times for reptiles in northern latitudes with pronounced seasons. The vernal (spring) equinox sees lots of activity following a long winter hibernation period. Males bask to encourage sperm production, then feed to get into breeding condition. Female emergence usually lags behind by a couple of weeks.


aSometimes things work out just fine if you leave them to the last minute; generally they do not. Today, however, was the former. I had my biggest ever NARRS reptile count - 87 common lizards and one slow-worm - in two hours walking round Redhill Common in Bournemouth, Dorset, at the very tail end of the season. Talk about leaving it late though...


The following was taken from the Buglife and Exmoor National Park Authority websites:

Buglife and Exmoor National Park Authority are appealing for sightings of White-clawed crayfish on Exmoor. The two organisations are working together on a new project to map the species on Exmoor. 


Rare snail shows up on Portland

We're engaged in lots of non-marine mollusc work at the moment; some of it relating to professional projects; some of it simply in the name of voluntary biological recording. Winter is a time for compiling all those species records collected throughout the year, and sending them off to the relevant Local Records Centres (LRCs).


Scottish Natural Heritage (SNH) has announced its intention to a carry out a survey of freshwater pearl mussels (Margaritifera margaritifera) across Scotland. It is currently seeking tenders from suitably-qualified contractors, to perform the survey in 2013 and 2014.
