How is botany evidence collected?
Abstract. Forensic botany is the use of plant evidence in matters of law. While plant fragments are often collected as trace evidence, they are only occasionally identified using microscopy and are still more rarely assessed using molecular biology techniques for individualization and sourcing of a sample.
How would a forensic botanist use habitat sampling to help solve a crime what type of information will this sampling provide?
A forensic botanist can identify individual plants from tiny fragments found on bodies, automobiles, and other objects. … It is possible to exclude possible crime scenes based on the habitat requirements of the recovered plant. Knowing a crime scene’s assemblage of plants can help identify its location.
How are plants and seeds most useful in forensic botany?
Most commonly, seeds are examined microscopically and identified to the plant species level to show a linkage between persons and places. More recently, forensic researchers have evaluated the potential for extracting and typing DNA from seeds to further individualize the samples.

Why are plants considered to be a great forensic tool?
The reasons for this are several: 1) plant remains can be found almost everywhere; 2) they offer multiple sources of evidence, both macroscopic and microscopic, such as pieces of wood, (even as charcoal), seeds, fruits, leaves, twigs, plant hairs, microscopic air-borne pollen and spores, or in aquatic environments, …
How would you collect soil evidence from a crime scene?
