Vector Diagrams

Vector diagrams can be useful in some situations and may suggest analyses and insights otherwise missed. They can be used to relate like factors in ecosystems and management units or can be effectively used to relate to how well objectives are being achieved. A sample is shown here. There are only 4 vectors from the center shown here but many such vectors or lines can be used. Each letter can be labeled as a topic such as wild faunal objectives

  1. small game
  2. waterfowl
  3. big game
  4. other-fauna
  5. etc.
or lists of resources such as soil, water, fauna, forests, recreation each with its own line or vector, equally proportionately distributed around the circle.

The level of achievement, relative to 100% at the arrow point at the outer reach of the circle is marked on each line and those points connected as with the dark line. The area inside the polygon is the level of achievement compared to the circle or the connected outer points. At * in the diagram, the objective has been exceeded and this condition may be seen in most situations as being as undesirable (misallocation of resources or catastrophe) as under achievement.

The diagram may suggest relations, continuua, and concepts of needed balance among vectors, and of course, disproportionate allocations.

Changes in the area from period to period can be impressive. The achieved area as a proportion of the potential area (all arrowheads connected by lines) can be uses as a gross managerial performance index.
