ABSTRACT Large‐scale marine protected areas (LSMPAs; > 1000 km 2 ) provide important refuge for large mobile species, but most do not encompass species' ranges. To better understand current and future LSMPA value, we concurrently tracked nine species (seabirds, cetaceans, pelagic fishes, manta rays, reef sharks) at Palmyra Atoll Kingman Reef (PKMPA) in the U.S. Pacific Islands Heritage Marine National Monument. PKMPA Exclusive Economic Zone encompassed 39% 54% of movements ( n = 83; tracking duration range: 0.5–350 days), respectively. Species distribution models indicated 73% contained highly suitable habitat. Under two projected scenarios (SSP 1–2.6, “Sustainability”; SSP 3–7.0, “Rocky Road”), strong sea surface temperature gradients initially could cause abrupt oceanic change resulting predicted habitat loss 2040–2050, followed by an equilibrium response regained 2090–2100. Current habitats were available adjacent to PKMPA, suggesting that increased MPA size enhance protection. Our three‐tiered approach combining animal with publicly remote sensing data environmental be used design, study, monitor throughout world. Holistic approaches diverse use can assessments area designs. Animal telemetry may helpful ascertaining extent which other MPAs protect future.
