Every conservation organization publishes an acreage number, and acreage is real — it’s the clearest, most auditable measure of how much land is permanently out of development’s reach. But acreage alone can be a misleading proxy for what actually matters to wildlife, and it’s worth explaining why our strategy has shifted, deliberately, toward connectivity rather than raw acreage totals.
A 400-acre preserve surrounded on all sides by roads, fences, and subdivision is genuinely valuable — it protects the plants, soil, and resident wildlife within its boundary. But most wildlife populations aren’t sustained by any single patch of habitat; they’re sustained by the ability to move between patches to find mates, follow seasonal food and water, and recolonize an area after a fire or drought wipes out a local population. A landscape of isolated habitat islands, however large each island is individually, slowly loses species that need to move between them — a well-documented ecological pattern called habitat fragmentation, and reversing it is harder and more expensive than preventing it in the first place.
This is the entire logic behind our Ridge-to-River Wildlife Corridor program. Antler Gap Forest and Bramble Ridge Preserve, protected in 2015 and 2019, are each valuable on their own. But our camera-trap data shows mountain lion, black bear, and mule deer using the specific wooded draw connecting the two — evidence the corridor function was already there before we had two adjacent protected parcels to prove it. Granite Creek Meadows, our current acquisition priority, isn’t valuable because it adds 180 more acres to a spreadsheet total. It’s valuable because, without it, the corridor stops dead at a fence line and a county road, and every acre we’ve already protected on either side of that gap does less than it could.
When you see our Living Map widget on the homepage show two preserves ‘grown’ together with an organic connecting corridor and two others sitting apart as ungrown gaps, that visual is not decoration — it’s a literal representation of the difference between protecting acres and protecting a corridor. Closing those two remaining gaps, at Granite Creek Meadows and Sentinel Bluff, is where we believe a gift right now does the most good.
