The name changes but the plant remains the same...

A recently published nomenclatural paper in the Nordic Journal of Botany looks like a precursor for the tranfer of Pulsatilla (Pasque Flowers) as a genus to a section within the genus Anemone. It has been known for a while that a number of well known genera like Pulsatilla and Hepatica are so genetically close to […]

Cars, lorries, planes, buses and lichen surveying

  With the help of the brilliant Lothian Buses journey planner I travel by bus today. Surely it’s one of the hottest days of the year so far.  Arriving at my destination, Queensferry Road, Edinburgh, the intense warmth of the sun is being reflected back at me from pavements, buildings, walls, cars and bus windows.

Pollution and Pests?

Regularly hitting moderate levels for pollution, as monitored and recorded by the 91 Air Quality Monitoring Stations that are situated across Edinburgh and the central belt of Scotland, I knew that Salamander Road in the north-east of the city was not going to be a biodiversity hotspot for lichens. Now my remit is to survey […]

Once is not always enough

Some sites you just have to visit twice.  Unexpected hail and snow blizzards when surveying are just part of the course, but add strong winds to that, and coldness that freezes your fingers so you can’t even hold a handlens up to the lichens you’re trying to identify and the will to battle on dwindles.

Exterminate, exterminate! – a portal into another world

I’m heading to a new part of town to find my next air quality monitoring station and to spice up the journey I take a route suggested by Cycle Streets –a brilliant online city cycle route planner. I find myself trundling along one of ‘Britain’s best cycle rides’ – a journey along the 35 mile […]

Air quality monitoring  - a view from the inside

Today as part of my survey on lichens as indicators of air quality we head out of the city to the foot of the Pentlands, well almost. Bush Estate. We are looking for a cleaner air site and there, in the middle of a field somewhere is one of the 91 air quality monitoring stations […]
