FIAP definition of Monochrome Photography:

A black and white work fitting from the very dark grey (black) to the very clear grey (white) is a monochrome work with the various shades of grey. A black and white work toned entirely in a single colour will remain a monochrome work able to stand in the black and white category. On the other hand a black and white work modified by a partial toning or by the addition of one colour becomes a colour work (polychrome) to stand in the colour category.

FIAP definition of Nature Photography:

Nature photography depicts living, untamed animals and uncultivated plants in a natural habitat, geology and the wide diversity of natural phenomena, from insects to icebergs. Photographs of animals which are domesticated, caged or under any form of restraint, as well as photographs of cultivated plants are ineligible. Minimal evidence of humans is acceptable for nature subjects, such as barn owl or storks, adapting to an environment modified by humans, or natural forces, like hurricanes or tidal waves, reclaiming it. The original image must have been taken by the photographer, whatever photographic medium is used. Any manipulation or modification to the original image is limited to minor retouching of blemishes and must not alter the content of the original scene. After satisfying the above requirements, every effort should be made to use the highest level of artistic skill in all nature photographs.

PSA definition of Nature Photography:

Nature photography is restricted to the use of the photographic process to depict observations from all branches on natural history, except anthropology and archeology, in such a fashion that an informed person will be able to identify the subject material and to certify as to its honest presentation. The story telling value of a photograph must be weighed more than the pictorial quality. Human elements shall not be present, except on the rare occasion where those human elements enhance the nature story. The presence of scientific bands on wild animals is acceptable. Photographs of artistically produced plants or animals, mounted specimens, or obviously set arrangements, are ineligible, as is any form of manipulation that alters the truth of the photographic statement. No elements may be moved, cloned, added, deleted, rearranged or combined. No manipulation or modification is permitted except resizing, sharpening, cropping, selective lightening or darkening, and restoration of original color of the scene. No special effect filters can be applied. Any adjustments must appear natural.
