There is a new stage in the survey process. After the 'Active' stage, where all the trees are inspected and the recommendations made, the survey can then be placed into the Work stage. A separate work team, estate staff or arboricultural contractors can carry out and record the work done. They can also take photos to show the results.
The important thing about the Work stage, is that none of the inspection details or recommendations can be changed - only the Work Done checkbox and notes can be updated.
