Stewardship Plan for Four Conservation Easements Held by the Town of Newfields
Get PDFIn 2005 the Town of Newfields, NH was awarded a grant by the New Hampshire Estuaries Project. The Eligible Activity applied for, under the category of Land Conservation and Natural Resource Protection was “Development of monitoring plans for town-held easements on conservation lands”. The Town identified four properties on which the they hold conservation easements as the focus of the project. Newfields’ goal in applying for the grant were to have each property visited by the contractor and a local volunteer, conduct an interview with the landowner and a conduct a ground monitoring of the property. Following the visits, baseline documentation reports and a stewardship plan for each easement property would be created. As a part of the plan, the Town also hoped to address policy considerations relating to stewardship of easements
Coagulation kinetics beyond mean field theory using an optimised Poisson representation
Get PDFBinary particle coagulation can be modelled as the repeated random process of
the combination of two particles to form a third. The kinetics can be
represented by population rate equations based on a mean field assumption,
according to which the rate of aggregation is taken to be proportional to the
product of the mean populations of the two participants. This can be a poor
approximation when the mean populations are small. However, using the Poisson
representation it is possible to derive a set of rate equations that go beyond
mean field theory, describing pseudo-populations that are continuous, noisy and
complex, but where averaging over the noise and initial conditions gives the
mean of the physical population. Such an approach is explored for the simple
case of a size-independent rate of coagulation between particles. Analytical
results are compared with numerical computations and with results derived by
other means. In the numerical work we encounter instabilities that can be
eliminated using a suitable 'gauge' transformation of the problem [P. D.
Drummond, Eur. Phys. J. B38, 617 (2004)] which we show to be equivalent to the
application of the Cameron-Martin-Girsanov formula describing a shift in a
probability measure. The cost of such a procedure is to introduce additional
statistical noise into the numerical results, but we identify an optimised
gauge transformation where this difficulty is minimal for the main properties
of interest. For more complicated systems, such an approach is likely to be
computationally cheaper than Monte Carlo simulation
