Bodies concerned with conservation need funds to carry out their conservation activities. This requires them to communicate effectively with potential donors or lenders. Economic factors can influence choices in this regard. Most donors like to see value for money or resources used so it is important to present a 'prospectus' or case well in this respect.

Some economic guidelines for presenting arguments to donors (or lenders) in relation to value for money are presented. Risk in relation to funding and investment portfolios for protected areas is discussed and the role of economists in providing financial advice is outlined.
