SPLATs vs DFPZ discussion

SPLATs vs DFPZ discussion by Kim_Ingram, at 2:36 p.m. on 18 March 2010,

The following was sent to me from George Terhune re. the SPLATs vs DFPZs discussion:

Thank you for responding to my comments, though of course that leads to further comments and questions. 1. If SNAMP is limited to a focus on 'the forest management alternative approved in the 2004 Record of Decision', how can it be an example of 'adaptive management'? In any case, you've already gone beyond the SPLAT strategy of the 2004 ROD by including a DFPZ example in the meta-analysis, and that is entirely proper, because the 2004 ROD acknowledged and supported the demonstration of the DFPZ strategy mandate by the HFQLG Forest Recovery Act. It's apparent that Congress intended the strategy to be taken seriously as a candidate for wider application. 2. I agree that a 'more fruitful exercise' can and should be the next step. But it should not be to compare implemented DFPZs to a theoretical SPLAT design. Since it isn't possible to implement both DFPZs and SPLATs on the same ground, the most useful direct comparisons would be theoretical to theoretical, which would not only be a fairer comparison, but it would permit manipulation of both DFPZs and SPLATs over a range of conditions and assumptions. For example, what performance is delivered by each theory when different percentages of the landscape have been treated? When the first 10% is treated? Then another 10% added? Then another 10% added? One of the largest differences that could be expected to show up would be how safely and effectiviely fire suppression would be supported by various implementations of each strategy. There should also be comparisons under strict and less strict rules regarding where and when management activity is permitted. Those comparisons are needed to support management decisions on how best to adapt to rapidly changing conditions, such as climate change and water supply effects, when balances must be established among competing priorities. Finally, there should be comparisons of economic effects from implementing each strategy, because the amount of treatment that can be done is limited by the cost efficiency of the management activity, and the availability of the workforce and industrial infrastructure to do the huge amount of work required also depends on the economic practicality and efficiency of management decisions. That isn't everything that needs to be done, but maybe it would be a decent start.
