Owner Values and Market Opportunities Market needs vary regionally Volume Quality Species Supply potential Ownership patterns Competition Owner values vary regionally Pennsylvanias Private Forests Persistent threats to forest stewardship happens when ownership changes Changes in ownership often result in changed management and use decisions Tenure D Most change at owner exchange - Timber harvesting - Parcelization PFL Future Plans
14% plan to sell forestland as is 12% plan to establish trusts 9% plan conservation easements 9% plan to subdivide 45% plan to let heirs handle it 30% plan to leave forestland to 1 child 50% plan to leave forestland to >1 child 57% - It is important to me that my forestland remain in the family (Parcelization Study) Pennsylvanias Private Forests While 80% of forest owners plan to keep forestland in the family D Only 40% have discussed the plan with their children D Only 35% of children are involved with the current forest plan
Even fewer landowners have a plan in place The Situation in Pennsylvani a In 2003, 375 600 forest and farm acres lost daily 64% forestland owners < 10 acres; 472,000 owners Average forest owner < 16 acres; Tenure < 13 years Changing land ethic with land use change NEED Approaches to conserve working forests Attaining Conservation: Depends on understanding values
Social Economic Ecological Challenged by Societal understanding? Acceptance of need? Commitment to resource stewardship? Conservation is not merely a thing to be enshrined in outdoor museums, but a way of living on the land; . . .It must ultimately prevail on all lands, public and private, or go down in history as a pleasant but futile pipe-dream. Aldo Leopold, 1927
In other words, always send the message to the neighbor with the best coordinates, closest to the destination coordinates. One may call this routing without routers (or routing tables). What is needed first is to embed the network into some...

Life in a Lake. Animals have adaptations that help them obtain what they need to survive. For example, water beetles use the hairs under their bodies to trap surface air so that they can breathe during their dives for food.
