Conservation-bank credits in California are issued against a specific listed species or habitat. The curated headings below make the market browsable without changing the underlying RIBITS classifications or implying that separately issued credits are interchangeable.
California Red-legged Frog Credits

The California red-legged frog occupies ponds, streams, and wetlands in California and northern Baja California. Adults have prominent dorsolateral folds, dark spotting, and reddish coloring on the underside of the legs and abdomen.
California Tiger Salamander Credits

The California tiger salamander is a large, stocky salamander native to California grasslands and vernal-pool landscapes. Its black body and irregular cream or yellow spots distinguish it from related species.
Coastal Sage Scrub & Chaparral Credits

California sagebrush (Artemisia californica), a characteristic plant of coastal sage scrub.
Coastal sage scrub and chaparral credits cover Southern California shrubland habitats and associated listed species. Each bank listing preserves the underlying RIBITS credit classification verbatim.
Covered here: Coastal Sage Scrub (5) · Southern Chaparral (3) · Coastal California Gnatcatcher (1) · Mafic Chaparral (1) · San Diego Barrel Cactus (1)
San Joaquin Kit Fox Credits

The San Joaquin kit fox inhabits arid grasslands and scrublands of California's San Joaquin Valley and adjacent areas. Its small body, exceptionally large ears, pale coat, and black-tipped tail distinguish it from larger foxes.
Burrowing Owl & Swainson's Hawk Credits

Western burrowing owl (Athene cunicularia hypugaea) — selected for this grouped section.
Burrowing owl and Swainson's hawk credits frequently occur together in California upland and foraging-habitat classifications. The two remain separate lookup topics, while shared classifications produce one bank row within this section.
Covered here: Swainson's Hawk (8) · Burrowing Owl (7)
Fairy Shrimp & Vernal Pool Tadpole Shrimp Credits

Vernal pool fairy shrimp (Branchinecta lynchi) — selected for this grouped section.
California vernal-pool crustacean credits cover Conservancy fairy shrimp, longhorn fairy shrimp, vernal pool fairy shrimp, and vernal pool tadpole shrimp. Each remains a separate lookup topic, while composite RIBITS classifications can truthfully belong to more than one topic.
Covered here: Vernal Pool Fairy Shrimp (17) · Vernal Pool Tadpole Shrimp (13) · Conservancy Fairy Shrimp (3) · Longhorn Fairy Shrimp (1)
Alameda Whipsnake Credits

The Alameda whipsnake occurs in chaparral and scrub habitats of the eastern San Francisco Bay region. Its slender dark body bears a broad yellow-orange stripe along each side.
Valley Elderberry Longhorn Beetle Credits

The valley elderberry longhorn beetle inhabits riparian woodland and foothill areas of California's Central Valley where elderberry shrubs grow. Males have red-orange wing covers with dark spots and longer, thicker antennae than females.
Callippe Silverspot Butterfly Credits

The Callippe silverspot butterfly occurs in grassland and open-hill habitats around the San Francisco Bay Area. Its larvae depend on native violets, while adults visit a range of flowering plants for nectar.
Desert Tortoise & Mohave Ground Squirrel Credits

Desert tortoise (Gopherus agassizii) — selected for this grouped section.
Desert tortoise and Mohave ground squirrel credits overlap in portions of California's desert conservation market. They remain separate lookup topics, and every bank row retains its original RIBITS classification.
Covered here: Desert Tortoise (3) · Mohave Ground Squirrel (1)
Tricolored Blackbird Credits

The tricolored blackbird forms large breeding colonies in wetlands and agricultural landscapes of California's Central Valley and nearby regions. Adult males are glossy black with a bright red shoulder patch bordered by white.
Giant Garter Snake Credits

The giant garter snake is associated with marshes, rice fields, and other aquatic habitats in California's Central Valley. Its long dark body typically bears a yellow dorsal stripe and pale lateral stripes.
Ben Lomond Sandhills Species Credits

Ben Lomond spineflower (Chorizanthe pungens var. hartwegiana) — selected for this grouped section.
Ben Lomond sandhills credits cover several plants and animals associated with the Santa Cruz sandhills. Each species remains a separate lookup topic, and the bank listing preserves every underlying RIBITS classification verbatim.
Covered here: Ben Lomond Buckwheat (1) · Ben Lomond Spineflower (1) · Ben Lomond Wallflower (1) · Mount Hermon June Beetle (1) · Silverleaf Manzanita (1)
Vernal Pool Plant Credits

Contra Costa goldfields (Lasthenia conjugens) — selected for this grouped section.
California vernal-pool plant credits cover several separately listed flowering plants and grasses. Each species remains a distinct lookup topic, while composite credit classifications can support more than one topic.
Covered here: Sebastopol Meadowfoam (4) · Sonoma Sunshine (3) · Contra Costa Goldfields (2) · Burke's Goldfields (1) · Hoover's Spurge (1) · San Joaquin Orcutt Grass (1) · Slender Orcutt Grass (1)
Vernal Pool Habitat Credits

Vernal pool fairy shrimp (Branchinecta lynchi) — selected for this grouped section.
These classifications describe vernal-pool preservation, pool-and-swale systems, watershed context, or composite habitat for several listed species. The public topics aid navigation without replacing the registry's original classification text.
Covered here: Vernal Pool (5) · Vernal Pool & Swale (2) · Goldfields, VPFS & CTS (1) · Vernal Pool & Watershed (1) · VPFS & Owl's Clover (1)
California Grassland Credits

Purple needlegrass (Nassella pulchra) — selected for this grouped section.
California grassland credits include native perennial grassland and non-native annual grassland classifications. These habitat types remain separate lookup topics and retain their original RIBITS labels in every bank listing.
Covered here: Non-native Grassland (3) · Native Grassland (2)
California Oak Woodland Credits

Coast live oak (Quercus agrifolia) — selected for this grouped section.
California oak woodland credits span creation, preservation, and woodland types identified by dominant oak or riparian setting. Each remains a separate lookup topic and keeps its verbatim registry classification in the bank listing.
Covered here: Coast Live Oak Woodland (2) · Oak Woodland (2) · Coast Live Oak Riparian Forest (1) · Engelmann Oak Woodland (1)
Salmonid, Delta Smelt & Longfin Smelt Credits

Delta smelt (Hypomesus transpacificus) — selected for this grouped section.
These California credits cover salmonids, Delta smelt, Longfin smelt, and composite aquatic or riparian habitat classifications. Each topic remains independently searchable while the bank listing preserves the complete RIBITS classification.
Covered here: Salmonid (3) · Delta & Longfin Smelt (2) · Tule Marsh (2)
Other Species Credits

Delhi Sands flower-loving fly (Rhaphiomidas terminatus abdominalis) — selected for this grouped section.
California conservation banks also hold credits for additional species, habitats, and program classifications with smaller or more specialized markets. Every bank listing retains its underlying RIBITS classification verbatim.
Covered here: Stream (2) · Active Wash - Unoccupied (1) · CFWO MSCP Tier I (1) · CFWO MSCP Tier III (1) · Delhi Sands Flower-loving Fly (1) · Delta Green Ground Beetle (1) · Dry Marsh/Riparian Scrub (1) · Golden Eagle (1) · Lakeside Ceanothus (1) · Mountain Lion (1) · Riparian Forest Floodplain (1) · San Bernardino Kangaroo Rat (1) · Santa Ana Sucker (1) · Seasonal Stock Pond (1) · Shaded Riverine Aquatic Habitat (1) · Upland (1) · Upland Buffer (1) · Water Dependent Habitat (1) · Western Spadefoot Toad (1)

About the data on this page
Bank details, status and credit balances are mirrored from the USACE RIBITS registry, the federal public record for mitigation banks. What we call a “credit sale” is a credit withdrawal — the entry written in the federal credit ledger when credits are committed to a permit. At commercial banks a withdrawal generally represents a sale; at a single-client bank it offsets the sponsor’s own project. The figures count ledger transactions, not distinct purchases — one purchase may produce several withdrawals — and we count entries rather than credits moved, because credit classes are different units and cannot be added together. Each bar in a sales chart counts the credit sales recorded in that calendar year — withdrawals from the federal ledger, not quantities of credits. The final bar is the year in progress and is shown in a different color. No bars means no sales in those years.
The species grouping is ours. We do this because the credit classification for a species displayed in RIBITS may take multiple forms and we want to show you all related supply in one place. Assigning those names to the species sections on this page is our editorial judgment, and a bank may hold species credits we have not placed in a section here.
