A land trust is a non­profit orga­ni­za­tion that works to pro­tect land through dona­tion or pur­chase. Land trusts work with will­ing landown­ers who wish to donate or sell their land or con­ser­va­tion ease­ments on their land for con­ser­va­tion pur­poses. Accord­ing to the Land Trust Alliance, there are over 1,500 land trusts in the nation.
