Birds use habitat in many, many ways – tracking can’t be linear
Concept -- A Hierarchical ApproachConcept -- A Hierarchical Approach
• AREAAREA (BCR part of a state)
– ASSOCIATIONSASSOCIATIONS (habitats with a suite of associated species)
• CONDITIONSCONDITIONS (Variations within habitat associations)
– SEASONSSEASONS (Breeding, Non-breeding, months, etc)
» SPECIESSPECIES (Found in each condition of each association)
“In BCR 18 - NM” “Shortgrass” “with few shrubs and moderate grazing” in the “ breeding” season for “Lark Bunting”

A link from landcover to birds (usually density, duck-use-days or shorebird-use-days).

% of Goal for Area
Then, if needed, develop habitat to meet goal.
MODEL
HABS: A tool that manages the concept, landcover, models, linkages and goals.
End Product: Area Implementation Plan (AIP)• Simple, specific, updateable• Shows current and desired
acres of habitat• Describes specific habitats
and priority species for work in that area
• Represents habitat goals over 30 years and reveals the magnitude of conservation work needed.
• Provides support for developing new conservation initiatives or tweaking existing ones
• Provides justification for budgetary requests

Conclusion
There are 159,129,630 acres of land in PLJV of which approximately 6,428,000 are permanently developed, leaving 152,697,742 to support birds, of which 12,891,769 need to change type or condition to meet priority bird goals.
