Topography

Reconstructing a non-surviving topographic feature to depict the documented historic appearance.

Reconstructing topographic features that cannot be documented historically or for which inadequate documentation exists.

Vegetation

Reconstructing a non-surviving vegetation feature to depict the documented historic appearance. Although historic genus, species and cultivar are preferable, substitute materials may be used as long as they recreate the historic appearance--namely, habit, form, color, texture, bloom, fruit, fragrance, scale and context. For example, reestablishing a lost corn field using a contemporary cultivar having the same habit and growth cycle.

Reconstructing vegetation features that cannot be documented historically or for which inadequate documentation exists. For example, installing a “period” herb garden.

Using substitute materials that do not convey the appearance of the historic vegetation.

Not reconstructing a documented vegetation feature; or replanting a feature but altering its historic appearance.

Failing to identify and interpret the reconstruction of a lost vegetation feature, thus confusing the public understanding.
