Incentives framed within a conservation agreement would be things like money to help somebody who can't otherwise pay for it to change their regime; reduce the headage, the number of cattle per hectare; change the timing.... Because they have a mortgage and a bank account, someone has to help this person out with their annual budget in order to modify their practices. So financial incentives of course are the big one. If you want to be very specific, that's the most powerful one.
