How to monitor a moor...

This short film made by one of our fantastic volunteers shows how we go about monitoring an area of moorland, and even includes a short cameo from a mountain hare:


You can see volunteers laying out quadrats (randomly placed squares used as a 'sample' of the moorland), installing equipment like peat anchors (for measuring peat depth), dipwells (for measuring water table) and a rain gauge (for measuring rainfall) amongst other things. Data from this kit will be downloaded monthly and used to see how the moorland is responding to climate change in the long term.

The film also shows the initial survey of the plants on the site - our volunteers answer questions like: Which species of plants are present? How tall are they? What condition are they in? Are there any signs of wildlife? This information will be collected every year to see if there is a trend or pattern of changes. 

Many thanks to Sergio for filming, to Eastern Moors Partnership and Sheffield City Council and all the volunteers who helped to set the site up. The film was mostly shot on Burbage Moor, with the hare footage captured near Bleaklow.

What is a dipwell?

In order to measure the water table (the level of water underground) on our Community Science environmental monitoring sites, our volunteers install dipwells. These are tubes which sit vertically the peat, and are drilled full of small holes to allow them to fill with water, which can then be measured.

Tom can be seen here drilling small holes into a dipwell, to allow it to fill with water.

When a dipwell is installed, a small amount of open tube sticks out above ground level. This open hole is the fitted with a cap (see pictures below). This is not to stop water from entering, but in fact to prevent small mammals like voles from falling down the tube!

The caps must have a hole drilled in them to allow the air pressure to be equal inside and outside the tube. If the pressures were different, the water level could be affected. After a while these caps can become bleached by the sun (see photo) or even chewed up by passing animals, so our volunteers keep an eye on them an replace occasionally them when needed.
