Traditionally, agriculture = downgraded

crowding Selection pressure: environment

modified by use of pesticides, resistant cultivars, planting date

Wealth of DataWealth of Data

Aside from scientists interested in conservation of genetics of crops & their wild relatives, few agricultural scientists see the value of their data to the biodiversity community Value in peer-reviewed publications, not data

publication Concern about losing control of their dataset

Biodiversity community has traditionally only paid attention to what is stored in museums or databanks

Integrated Pest ManagementIntegrated Pest Management

Sets an economic threshold for making decisions on strategies for maintaining pests at, or below a threshold of economic loss (economic injury level)

The choice of strategies can conserve Biodiversity Water, air, & soil quality money

Implications of Darwin Core for Agricultural Data

Implications of Darwin Core for Agricultural Data

Simple Darwin Core Most agricultural

data fit rows/columns

Fields used only once

No minimum/ maximum data

Will include samples with 0 to multiple observations for a taxon

ConclusionsConclusions

If we want to incorporate agricultural datasets into our biodiversity assessments, we will need to work with these scientists to make it easy to provide their data in a format that is fit for use by the biodiversity community.
