Conserving Biodiversity on Private Lands

Regional and Local Land Managers
Regional Land Managers
• Federal land managers (National Parks, National Forest, NWRs, etc.
• State land managers (DNR, State Wildlife Areas, etc.)
Local Land Managers•County planners•City planners•Private land managers and owners
Regional Land Managers manage relatively large blocks of land
Local Land Managers manage relatively small land parcels
Regional land managers have many advantages
• Manage parcels often large enough to maintain viable populations of many species
• Can make long-term plans (within political swings)
• Have biologists to interpret a constant flood of conservation studies and recommendations
Local land managers face many difficulties
• If city/county planners, they manage a few small parks and have limited control over zillions of small private parcels
• Private land owner reactions to city/county plans range from enthusiastic to hostile
• If a private land owner, they have only their own parcel and little control over neighbors
Local land managers face many difficulties (continued)
• Can rarely afford to hire biologists to help sift through a mountain of information
• When they can hire biologists, biologists may pinpoint priority locations incompatible with existing plans, zoning, or land ownership
Merging Local Land Planning with Conservation is So Difficult
Why do it?
Why not let regional land managers have all the conservation
responsibility?• 45% of lands in WA are in public
ownership
• 26% a combination of National Park, National Forest, Wilderness, NWRs, BLM
Isn’t that enough for biodiversity?
Neither land ownership nor species are randomly distributed
American Bittern – modeled distribution in Washington
Public land ownership in Washington
American Bittern example
• A secretive bird of marshes
• 88% of its breeding range and 89% of non-breeding range on private land
• No state or federal listing, but seems to be declining throughout its range and in the Pacific NW
• Even if all state and federal land were completely protected, little of the bittern’s range would be protected
Well-protected Habitats
• High-elevation• Dry• Rocky• Rugged• Cold
About 83% of alpine habitat in Washington is protected. Less than 1% is privately owned.
Poorly-protected Habitats
• Low-elevation• Fertile• Gentle terrain
Less than 1% of the Palouse of eastern Washington is protected. About 97% is privately owned.
Conservation actions taken by local land managers are as
important as those of regional (state and federal) land managers
How does a local land manager manage for biodiversity?

Our Goals
• Determine the species and habitats likely to be most affected by local land planning
• Put each county in a regional perspective
• Suggest conservation goals for each county
Non-goals
• Identify specific locations (with rare exceptions) as conservation priorities
• Not meant as a substitute for state and federal regulations
• Each county has unique ecological communities that pass through our coarse filter
• Doesn’t address most coastal/marine species or fish
Local Priority Species
• Species most likely to be affected by the actions of local land planners
• Terrestrial vertebrates only (no fish, no marine reptiles, mammals, or birds)
• Generally also excluded vertebrates that rarely ventured inland more than a few feet from shore, but included many species that used both shore/marine habitats and inland habitats (e.g., Peregrine Falcons
Local Priority Rank
• Local Priority Scores assigned to 4 categories
• A – Highest Local Priority
• B – High Local Priority
• C – Moderate Local Priority
• D – Not a current Local Priority

Land managers don’t usually manage species. They manage
land.
Local Priority Species → Local Priority Habitats
• Macrohabitats
• Mesohabitats
• Microhabitats
• Actions
Priority Macrohabitats
• Open natural vegetation (prairies, etc.)
• Late seral (old) forests, esp. at low-elevations
• Large rivers and lakes
• Shore/coastal (partly addressed)
Priority Mesohabitats
• Ponds and small lakes, esp. without introduced fish or bullfrogs
• Shrub, hardwood dominated riparian areas• Small streams, seeps• Marshes, swamps
Priority Microhabitats
• Snags, downed logs, brush piles
• “Untended” vegetation patches
• Talus slopes• Caves (for Townsend’s Big-
eared Bat)
Needs other than habitat
• Varies widely with species• Some examples
– Education on coexisting with large carnivores (mainly by avoiding human-carnivore interaction)
– Discourage use of lead shot (Trumpeter Swans)– Discourage/regulate pesticide use, esp. insecticide – Discourage feeding of nest predators (corvids,
coyotes, raccoons, squirrels, etc.) and exotic species via pet food left outside, garbage, intentional feeding
– Nest box installation– Encourage tolerance of raptors

Put Counties in a Regional Perspective
• Western Washington counties fairly uniform in priority habitats and species → Priority habitat suggestions generally apply to all counties
• But, each county has its unique characteristics
Comments
• Emphasis on habitat, not species
• Species should be used as barometers of success or failure
• Give regional perspective to county planners and offer suggestions, but do not identify specific locations as priorities
“Ask Me Again in Ten Years”
• Effective conservation requires regional perspective
• Effective conservation requires both regional and local implementation
• Local land managers need information they can translate into the action of numerous individuals with small plots of land
