It is important to consider the following points before commencing fieldwork:

· Proper preparation before going to the field is critical to ensure a successful field sampling campaign, and for the safety and well-being of the field team. Prior to any field campaign, it is important to have a good understanding of the area to be surveyed, including its topography, climate and vegetation characteristics, accessibility, and its security situation.

· Collate existing information about the area to be surveyed including: maps (topographical, geological, soils and/or vegetation), satellite images and/or historical aerial photographs, long-term weather station data, government statistics, census data etc.

· Load coordinates of sampling locations into the GPS units before going to the field. If possible, load local maps into the unit to aid in navigation in the field.

· Do a thorough equipment check before leaving for the field.

· When conducting field campaigns in new countries, it is generally recommended you conduct a reconnaissance survey during which local contacts are established and agreements made.

· Obtain permission from the land owner(s) to sample a given area, and make sure that he/she understands what you are doing. Inform local government officers and community leaders about your activities.
