The extent of travel can depend on pzlynology variety of factors including the strength and direction of the wind, the weight and shape of the grain, and atmospheric conditions, though the pollen will typically fall within around 2km of the parent plant.
Palynology Forensic disciplines Forensic palynology. If a suspect was present at a particular crime scene at which pollen can be found for instance a field or gardenthey may have picked up pollen on their clothing or in their hair. His body could not be found.
That indicates that the body was moved.
Pollen grains typically have a fairly hard coat to protect them as they pass from one plant to another, making them relatively resilient to destruction. All of these features make them especially ideal for use in a forensic investigation. Pollen and Spores Pollen refers to a powder containing the male gametophytes of seed-producing plants, produced and dispersed in order to pollinate and reproduce.
From Wikipedia, the free encyclopedia. Civil and criminal investigations.
The morphology of pollen and similar substances is fairly complex, meaning that with the appropriate equipment, expertise and reference materials, it is possible to distinguish between and identify pollen grains. In addition to this, scanning electron microscopy SEM may be utilised. The defendant was confronted with this new piece of information, at which point he finally cracked and confessed to the murder.
Pollen grains are dispersed in a variety of ways. Pollen and spores provide clues as to the source of the items and the characteristics of the environments from which the forfnsic on them is sourced. Pollen recovered from a suspect that happens to match that of a crime scene may simply suggest that the individual had visited that area at some point recently, not necessarily prove that they have committed a crime.
The use of spores and pollen. Of course despite the links palynology may establish, further evidence may be needed to support any conclusions reached.
Mildenhall”Hypericum pollen determines the presence of burglars at the scene of a crime: Whilst on a trip down the Danube River, an Austrian man disappeared. A person can easily inadvertently pick up pollen from a crime scene, whether it be foreneic mud on their shoes or on their clothes from directly brushing against a plant in the area. Furthermore, with the development of multi-disciplinary approaches to environmental analyses of crime scenes, far more detailed information is now available to law enforcement agencies, enabling them to determine with greater accuracy what may have happened during the commission of criminal activities.
An example of forensic palynology”, Forensic Science International3: It may even be possible to estimate the time of year at which a crime took place.

The study of pollen can also be used to determine the travel history of an item.
This may particularly be suspected if the body carries large amounts of a particular pollen that is not found at the location in which the body was found.
Forensic palynology: why do it and how it works.
With so many publications and high-profile cases involving forensic palynology and environmental analysis now receiving publicity, the future of this branch of forensic science is assured. Why do it and how it works. Finally, autogamous plants are self-pollinating, so the pollen they produce does not need to travel.
For instance, it may be possible to link a suspect to an object, a vehicle to a crime scene, or even link two separate incident scenes.
