PAGB New Nature Definition - No Human Intervention should be included

PAGB e-News 171: The new Nature Definition states that No Human Intervention should be included
in nature photographs - what does that mean?
Article text
Recently PAGB received this (edited) question.
We have just received our club’s DVD of the GB Cup entries, for which we are very grateful. In watching parts 1 & 2 Nature we noticed the inclusion of 'Human Intervention' included in a number of images i.e. Traffic Lights, Fence Posts, Barbed Wire, Gates and even two Jackdaws with peanuts. We thought that the new Nature Definition stated that No Human Intervention should be included in nature photographs?
Since there is probably widespread confusion on this issue we thought it worth publishing here.
Please note that our reply indicates policy for PAGB competitions and other organisations may not agree.
PAGB Response to question ......
The definition was developed in discussion between FIAP and the PSA and, despite problems with the English translation, was agreed by the RPS, and later, adopted by the PAGB. Nature photography is restricted to the use of the photographic process to depict all branches of natural history, except anthropology and archeology, in such a fashion that a well-informed person will be able to identify the subject material and certify its honest presentation.
The story telling value of a photograph must be weighed more than the pictorial quality while maintaining high technical quality. Human elements shall not be present, except where those human elements are integral parts of the nature story such as nature subjects, like barn owls or storks, adapted to an environment modified by humans, or where those human elements are in situations depicting natural forces, like hurricanes or tidal waves. Scientific bands, scientific tags or radio collars on wild animals are permissible.
Photographs of human created hybrid plants, cultivated plants, feral animals, domestic animals, or mounted specimens are ineligible, as is any form of manipulation that alters the truth of the photographic statement.
No techniques that add, relocate, replace, or remove pictorial elements except by cropping are permitted.
Techniques that enhance the presentation of the photograph without changing the nature story or the pictorial content, or without altering the content of the original scene, are permitted including HDR, focus stacking and dodging/burning.
Techniques that remove elements added by the camera, such as dust spots, digital noise, and film scratches, are allowed.
Stitched images are not permitted.
All allowed adjustments must appear natural.
Color images can be converted to greyscale monochrome.
Infrared images, either direct captures or derivations, are not allowed.
Please note that GPC does not currently apply these rules to GPC nature competitions.
