- Cultural contexts: The most important consideration when designing a sampling strategy for a cultural context is to fit the sampling design to the research objectives. For example, if the objective of the study is to identify activity areas, it may be ideal to sample using a grid system. If the objective is to identify foodstuffs, it may be more beneficial to focus on areas where food processing and consumption took place. It is always beneficial to sample ubiquitously throughout the site, because it is always possible to select a smaller portion of the samples for analysis from a larger collection. Samples should be collected and labeled in individual plastic bags. It is not necessary to freeze the samples, or treat them in any special way because silica is not subject to decay by microorganisms.
- Natural contexts: Sampling a natural context, typically for the purpose of environmental reconstruction, should be done in a context that is free of disturbances. Human activity can alter the makeup of samples of local vegetation, so sites with evidence of human occupation should be avoided. Bottom deposits of lakes are usually a good context for phytolith samples, because wind often will carry phytoliths from the topsoil and deposit them on water, where they will sink to the bottom, very similar to pollen. It is also possible and desirable to take vertical samples of phytolith data, as it can be a good indicator of changing frequencies of taxa over time.
- Modern surfaces: Sampling modern surfaces for use with archeobotanical data may be used to create a reference collection, if the taxa being sampled are known. It may also serve to "detect downward movement of phytoliths into archaeological strata". Taking point samples for modern contexts is ideal.
Famous quotes containing the word strategies:
“By intervening in the Vietnamese struggle the United States was attempting to fit its global strategies into a world of hillocks and hamlets, to reduce its majestic concerns for the containment of communism and the security of the Free World to a dimension where governments rose and fell as a result of arguments between two colonels wives.”
—Frances Fitzgerald (b. 1940)
