What counts as protected
“Protected” means land owned by a public agency or the Land Trust as parks and preserves, or held under a permanent conservation easement.
School grounds and private reserves are green space, but they aren't permanently protected, so they're counted only in the 17% figure.
How this correlates with Bainbridge Island Land Trust's reporting: the Land Trust reports protecting more than 1,500 acres with its partners since 1989, and holds 48 conservation easements covering more than 750 acres. Many of those acres, such as Gazzam Lake and the Grand Forest, are now owned by the Park District, so adding the two totals would count them twice. This page uses one inventory that counts each acre once.
Conservative estimate: the inventory includes 253 acres of Land Trust easements. Some easements on private land aren't included, so the true protected share is likely somewhat higher than 13%.
