One of the greatest difficulties in habitat conservation is that it's just very expensive. Land is expensive, and good land is even more expensive, because it tends to be in areas that are near water, which is recreational property. Good regional planning helps identify the most important areas, and that, in turn, helps conservation organizations invest their money most wisely. Planning like that is an important thing. On a big, regional basis like that, it takes a lot of time and money, and so it's not something an individual organization can typically take on.
