Follow the patch, not the changing photograph
Choose fixed viewpoints that show the edge of work and identifiable retained trees, and keep the original scope with the photographs, so that a later adviser can distinguish regrowth within the cleared boundary from plants on neighboring ground photographed from a different direction. Keep the originals.
For a hypothetical record, mark four equal ten-by-ten-foot patches, giving 400 square feet of observation area. Suppose the later visit finds stump-connected shoots in two patches, seedlings in one and retained native growth in one. That is two distinct unwanted-growth problems, not 400 square feet that automatically needs the same machine again.
The numbers describe this example only; they are not a field survey or a prediction of regrowth.
Photograph the same marked patches after clearing and again as plants develop. Separate shoots attached to cut stumps from new seedlings and from desirable plants you intend to retain. A green surface is not evidence that the original cutting failed, and an open surface is not evidence that invasive roots or seeds are gone.
Use the record to choose the next treatment with a qualified adviser rather than automatically buying another full clearing pass.
What should I record in the first growing season?

Three details that make buckthorn easier to recognize
Vermont Invasives describes common buckthorn leaves as 1.5–3 inches long with 3–4 pairs of curved veins, and places its fruit ripening in August–September. Use those features with the fact sheet’s other identification details; one leaf or a dark berry alone is not sufficient identification. Mark uncertain plants for an adviser.
The same reference reports a persistent seed bank and vigorous regrowth from surviving roots or stumps. A first-year photograph can document change but cannot establish eradication. Keep dates and plant identities with the treatment record, including the purpose of any later work by a certified applicator and the marked plants that were to be protected, because a later inspection needs to distinguish a missed target from a plant deliberately retained.
Decide what the next visit buys
The Vermont Invasives small-woodlot article describes repeated cutting over several years as a commitment that needs realistic labor and timing. Ask whether the next visit is identification, selected resprout treatment, seedling removal or another access pass. Keep those tasks separate on the proposal.
Do not drive a mower through a newly opened patch simply because the vegetation is lower. Record exposed wire, stone, retained stumps and changes in grade for the person choosing equipment. The original clearing finish and the safe mowing surface may be different purchases.
