The Juniper Survey
One of the things to look out for, during assessment, is a fungi called Gymnosporangium clavariaeforme. This is a parasitic 'rust' that infects the branch wood of the Juniper, causing it to swell. The fungi need two host plants to survive, infecting each one in rotation. In this case Rosaceae and Juniperus.
The juniper survey includes measuring height and diameter, as well as assessing the general condition. Each specimen is plotted on a map using GPS equipment and individual photographs taken, to complete the record. All of this information is held on a data base and the survey will be repeated in ten years time or if the management of the site changes radically.

As you can see (image right), Juniper is subjected to many conditions that affect the viability of the plant. In this instance, the competing Elder will be weeded out, to reduce the competition for minerals, light and water, thus giving the Juniper the best chance of survival.
