Global ChangeGlobal Change
• There are two major components of global change: climate change and land use change.
• Global change reduces biodiversity, modifies hydrological systems, and alters global biogeochemical cycles all of which have significant impacts on human and natural systems.
Extent of Land Use ChangeExtent of Land Use Change
• During the last three centuries, nearly
1.2 million km2 of forest and woodland and
5.6 million km2 of grassland and pasture have been converted to developed land uses on a global basis.
• Between 1982 and 1997, 121,000 km2 of non-federal land in the U.S. were converted to urban uses.
• Through its impacts on the quantity and quality of fish and wildlife habitat, land use change has contributed to the dramatic 1,000-fold increase in species extinction that occurred during the past 400 years.

Objectives of StudyObjectives of Study
• Simulate the economic and land use impacts of alternative economic growth-land use policy futures for Flathead County, Montana.
• Assess the impacts of the simulated future changes in land use on wildlife habitat.
• My presentation will focus on the first objective.
Stats for Flathead County Stats for Flathead County
• Size of county: 13,605 km2
• 78.6% of the land is managed by the federal government
• 82.5% of the land is controlled by federal, state, and tribal agencies
• 21.4% of the land is privately owned • 17% of the privately-owned land is zoned• Current population is 88,473
• 810,000 ha are forested• 405,000 ha are designated
wilderness• Flathead Valley’s elevation is 914
m• The tallest mountain peaks are at
about 3,050 m.
Natural ResourcesNatural ResourcesBob Marshall-Great Bear-Scapegoat Wilderness complex, Flathead National Forest, and the west side of Glacier National Park.
Glacier National Park is a Biosphere Reserve, and part of Waterton-Glacier International Peace Park, which is a World Heritage Site and the world’s first international peace park.
Despite its temperate climate, the county contains a highly diverse flora and fauna with 300 species of aquatic insects, 22 native and introduced species of fish, and nearly all of the large mammals of North America.
Threatened and Threatened and Endangered SpeciesEndangered Species
• Threatened species– grizzly bear– Canada lynx– bull trout– water howellia– spalding catchfly
• Endangered species– whooping crane– gray wolf
Importance of Open SpaceImportance of Open SpaceA 2002 attitudinal survey of Kalispell residents indicated that 42% of the respondents agreed with the statement that there is adequate undeveloped open space in the community; 76% indicated they were concerned about the potential loss of existing open space.
• The North Fork Valley which contains the North Fork Flathead River is west of Glacier National Park.
• This valley is considered one of the wildest valleys with the highest concentration of grizzly bears in the contiguous 48 states.
The Flathead River has 97.9 miles designated as wild, 40.7 miles as scenic, and 80.4 miles as recreational.
Flathead Lake is one of the 300 largest lakes in the world and the largest body of freshwater in the western United States.
EconomyEconomy
• Historically, the Flathead economy was highly dependent on extractive resource industries, including lumber and wood products, agriculture, and mining.
• Labor earnings in those industries dropped from a high of $97 million in 1993 to $75 million in 2000.
• Tourism and outdoor recreation are major sources of income and employment in the county.
• 40% of all personal income is the county comes from non-labor sources (i.e., transfer payments from investments, retirement accounts, and social security).
• Overall, the economy has been strong and continues to grow due to a steady wave of new migrants and seasonal residents that are attracted to the area because of its abundant environmental amenities and quality of life.
• Per capita and median incomes have been steadily rising, poverty is falling, and unemployment was at a 30-year low before the current recession.
• Flathead Valley and outlying areas are losing open space due to land development.
• Much of the developed land was previously in agricultural uses.
• In the last 30 years, 42,998 ha of farmland in Flathead Valley have been converted to developed uses.
Methods Used in StudyMethods Used in Study• Remote sensing• Land cover classification• Geographic information systems• Land use change analysis• Alternative futures analysis• Economic impact analysis• Surveys
Alternative Futures AnalysisAlternative Futures Analysis
• It is difficult for planners and stakeholders to foresee the potential ecological and economic consequences of their choices, policies, and plans because no one knows for sure what the future will bring.
• Since no single vision of the future is accurate or
superior to others, it is useful to model a set of alternative futures for a region that encompasses a spectrum of possible futures.
• Alternative futures analysis allows a community to assess the possible ecosystem and economic consequences of alternative assumptions about future growth and development.

Specification of Alternative FuturesSpecification of Alternative Futures
• Three economic growth scenarios specify growth rates in 11 industries between 2000 and 2014, and between 2014 and 2024.
• Three land use policy scenarios impose restrictions on residential and commercial-industrial development, and natural resource conservation.

• Economic growth rates were used in conjunction with IMPLAN multipliers to estimate the increase in employment for each industry and total employment for the three growth scenarios.
• A productivity adjustment was applied to the multipliers to account for improvements in technology that are likely to occur during the two time periods. The adjustment was based on forecasts of productivity increases published by the U.S. Bureau of Labor Statistics.

- High = 2.8 units per hectare - Urban = 2.2 units per hectare - Suburban = .8 units per hectare
- Rural = 1 unit per 2.5 hectare - Exurban = 1 unit per 3 hectares - Agricultural = 1 unit per 19 hectares
• Setbacks of new housing and C&I units from water bodies for land use policy scenarios:
Policy scenario Setback distance Baseline 6.1 m Moderately restrictive 10.7 m
Highly restrictive 15.2 m
• Treatment of environmentally sensitive areasTreatment of environmentally sensitive areas
The current land use policy scenario imposes no restrictions on the housing densities in environmentally sensitive areas.
The moderately restrictive land use policy scenario allows urban, suburban, rural, exurban, and agricultural densities in a 1.61 km wide buffer area around environmentally sensitive areas.
The highly restrictive land-use policy scenario allows only suburban, rural, exurban, and agricultural densities in a 1.61 km wide buffer area around environmentally sensitive areas.
None of the land use policy scenarios allow the construction of new CI&I units in the buffer areas.
• Development and sewer accessA sewer accessible parcel is located within
the 2003 growth boundaries established for the three incorporated cities (i.e., Columbia Falls, Kalispell, and Whitefish) and the boundaries for the four unincorporated cities (i.e., Bigfork, Evergreen, Hungry Horse, and Lakeside).
Only CI&I, and high, urban, and suburban density housing is allowed on developable, sewer-accessible parcels.

Interpretation of ResultsInterpretation of Results
• Whether land surpluses or land shortages occur depends on the alternative future.
• Although land shortages decrease as economic growth decreases, it is not politically feasible to control growth in Flathead County.
• Continuation of current (2005) land-use policy can lead to land shortages in the period 2000-2014 with the high growth scenario, and in the period 2014-2024 with the moderate and high growth scenarios.
• It appears that potential land shortages can be alleviated by implementing a more restrictive land use policy.
CaveatsCaveats• As land requirements for new housing and C&I
units approach the remaining amount of developable land, land prices would increase.
• Higher land prices would alleviate land shortages.
• Higher land prices would drive up housing costs, decrease housing affordability, and adversely impact limited-income families.
