Planning history in PNW Politics and Planning Implications for planning Stochastic MappingMultiple Use is Unavoidable: Multiple Use is Unavoidable Water quantity insensitive to management but quality can be affected by management Recreationalists can’t be excluded but can be encouraged with facilities Wildlife lives there anyway but clearcuts favor game; no cuts favor owlsMultiple Use: Which Use Shall Be Master: Multiple Use: Which Use Shall Be Master American Politics drives multiple use management in the forests of the West. There are three distinct political and management regimes: Pre, During, and Post Owl Management tools adapt to the politics Management plans adapt to the politics: Does the planner matter?Postwar and Pre-Owl: Postwar and Pre-Owl Political agreement on timber Informal tools--discretion Planning: Old Style: Planning: Old Style Planner professional forester knowledge of resource Owner preferences over uses supplies capital Planning job determine preferences determine budget find best plan among feasible plans easily amenable to programming formulation, but there was no need to do so!The Catch: The Catch The catch was that there needed to be an owner. A close substitute would be wide consensus on the appropriate goals and a political willingness to let the planner determine the goals within that consensus. Before ~1970, management of the Forests was not so contentious. Multiple Use Sustained Yield Act of 1960: Multiple Use Sustained Yield Act of 1960 Multiple Uses recreation range timber watershed wildlife fish (later wilderness is added) No one use is to predominate “High level annual … output without impairment of the productivity of the land”Agency Freedom: Agency Freedom The USFS had ample latitude to operate forests as it wished under MUSY of 1960. The act codified what USFS was doing anyway. The Agency was trusted and political consensus was pretty high. This was easy because there were substantial areas untouched by cutting.Old Stated Objectives: Old Stated Objectives Community Stability: JOBS coincident with mill profits Supply of Fiber (that’s wood) Recreation Game and Fish Scenic Drives Hiking Went together: More wood is more jobs is more open forest is more gameWilderness Act (1964) : Wilderness Act (1964) FS had designated wilderness on its own and was now constrained by law on those areas. Forced to study additional lands for inclusion. Large single purpose reserves went against the Multiple Use grain. The Planner would not decide which lands to reservePolitics and Formalized Planning: Politics and Formalized Planning Oddly played out through acts thought to innocuous or planning acts National Environmental Policy Act Endangered Species Act Resource Planning ActNEPA: NEPA Before a major federal action can be taken, the agency must Get public comment on issues to be considered Make a plan (Environmental Impact Statement) and several alternative plans Get public comment on the plans Choose a preferred alternative This was not thought to be radical legislation.Resource Planning Act (‘74): Resource Planning Act (‘74) Resource assessment at the National level Targets for Regions and Forests Plans to meet those targets This act was a way for the FS to get long term agreement by Congress on goals and for the Industry to get a clear mandate to produce wood.RPA Didn’t work : RPA Didn’t work Environmentalists wanted more wildland than the FS was planning for. Monongahela Decision: Resurrected language in 100 year old law that made it necessary to consider each tree before cutting. Clear need for new legislationNational Forest Management Act (1976): National Forest Management Act (1976) Political compromise Non-declining flow meant to preserve oldgrowth would only delay cut out CMAI meant to put teeth into sustained yield ecologically meaningless: trees still too smallEndangered Species Act: Endangered Species Act Can’t take animal, even on private land Take includes remove habitat Must list habitat to be protected Leads to legal question: when does regulation become confiscation of property? Current answer is when no economic use possible Participation: Participation RPA Interdisciplinary Teams (Regs. Restored supervisors power) Public comment Full written disclosure to public ESA Public right to sue to protect animals Public could see and could sueFormal Planning : Formal Planning Under NFMA and RPA, formal planning for multiple use was carried out by linear programming. The basic idea was to maximize present value of timber, subject to CMAI, non-declining flow, and other constraints. The Spotted Owl became the most celebrated constraintSimpleForest Planning: SimpleForest Planning Type of Site, j Many “birthdays” hj(t,s) t is calendar time s is birthday of stand h is acres harvested Dj(t-s) is volume per acre v(t) is cut at t v=j s Dj(t-s) hj(t, s) Max present value of P times V s.t. biology v(t+1) v(t) t-s > CMAI or h = 0Biology: Biology Initial Acres = Cut over all time Aj(s) = t hj(t,s) W is what is left standing wj(s,t) = Aj(s) - t hj(t,s) or =s hj(t,s) - a hj(a,t) Cut acres regrow and are recut s hj(t,s) = a hj(a,t) This is Johnson and Scheurman, Model II.More meaning to the model: More meaning to the model Types of sites, j different species site classes critical locations near streams visual buffers More Constraints Don’t cut type j Keep N% of forest at age, t-s, > 100 constraint on w More treatments commercial thin pre-commercial thinTraditional Problems with Planning : Traditional Problems with Planning Find the Cut Plans were not spatial Foresters still had to designate specific parcels to be cut Hard to see cumulative effect of decisions because of mapping technology The problem (Hrubes) The cuttable land base was much smaller than the planned land base because of streams, Indian burial grounds, needed habitat, etc. Difference only discovered when “finding the cut”Allowable Cut Effect: Allowable Cut Effect To get nondeclining flow cut oldgrowth now plan to cut unprofitable trees later When later comes, make new plan and don’t cut remote trees Thus cut declines under non-declining constraint. Industry likes this. They get more wood Environmentalists hate this. They see oldgrowth cut down sooner. It is an example of “no commitment”Forest Plans Took Forever: Forest Plans Took Forever Not innocent: Old plans used while waiting. Once it was clear that the plans would call for less timber, industry and Republican administration did not want plans to be final Environmentalists obliged by obstructing plans for their goals.

Chris Costello, unpublished 1998.Median Voter (Shalit): Median Voter (Shalit) Assuming that preferences are single peaked in commodity/amenity space and that voters decide the allocation between these uses, Shalit (unpublished 1976) uses the median voter theorem to find the actual allocation. He notes that the outcome is not pareto optimal and shows how side payments can be used to achieve a PO.Money and Votes (Peltzman, 1976): Money and Votes (Peltzman, 1976) Timber Beast wants gov’t to cut timber. Cutting unpopular with voters. Timber Beast donates money for political campaigns. Voters respond to campaigns Beast gives politicians enough money to overcome voter dislike of cutting. Political Business Cycle (Ken Rogoff): Political Business Cycle (Ken Rogoff) Presidents last only four years till re-election. That gives them a short time horizon and induces a political business cycle. Take the downturn at the beginning of term so that the recovery will be well underway by re-election. The Senator from Washington (and Idaho) needs rural votes. Shift timber harvest to the present to buy votes even if there is a severe restructuring later President’s plan starts high and ends low. Simple Stochastic View: Simple Stochastic View Goals for timber, owls TG, OG V = min E t (T- TG)2 + b(O - OG)2 (1+r)-t r is interest rate b is price of owls relative to timber s.t. biology, other constraints as before Clinton’s selection of Option 9: TG = 1.2 billion, long run; OG high.

No commitment to carrying out the plans. Shift (for a while) with the political winds. old-growth dependent species on a one way trip. Once the habitat goes, no later plan can bring it back. They will lose out a piece at a time. The Planner will look like a fool.Forward and Backward: Forward and Backward The Biologist rules the roost. They will plan with mapping tools to get the forest condition that they want. They will do it “by eye” An optimization will be after the fact and only on lands they do not consider important.
