The Open Air Laboratories (OPAL) networks are looking for people, schools and organisations to join in and assist with their air survey in England. Good air quality is essential for our health and for the wellbeing of our environment.

The lichen is a community of two or more organisms living together. The lichen has a symbiotic relationship between a fungus and an alga. The fungus protects the alga, which in turn provides food for the fungus through photosynthesis.

Glen, based at the northern office in Manchester will be carrying out the air survey at the Chorlton Meadows nature reserve. The survey involves studying lichens on trees and looking for tar spot fungus on sycamore leaves.

Once your survey is complete the results can be recorded online and the results can be viewed across England in the form of maps. Further information and helpful guidance can be found on the OPAL website (http://www.opalexplorenature.org/?q=AirSurvey).

Dr Paul Beckett (pictured), together with Uliana B. Bashtanova and Timothy J. Flowers, has recently had a paper on the chemical control of knotweed published in Weed Science.  It contains some interesting information on the possible timing of different herbicides and the physiological action of these herbicides. Testing of the theories mentioned in the field directly will be done in a more systematic way under experimental conditions as part of the next phase of research activity.
