Right now, the best opportunities appear to be with the private land trusts and national land trust organizations, as opposed to the federal agencies. With little exception, none of the federal agencies is expected to see big growth over the next few years. On the other hand, following the slight slowdowns of the early and late 1990s, the private land trusts are growing.
Land trusts are the fastest growing arm of the conservation movement today, with more than 1,000 private nonprofit land trusts, according to the Land Trust Alliance (LTA). The LTA National Land Trust Census, conducted every five years, reports that local, state, and national land trusts had conserved 56 million acres of open space as of December 31, 2015—an increase of 9 million acres since 2010.
