NED-1: integrated analyses for forest stewardship decisions

Decision Support Systems for Forestry in Galicia (Spain): SaDDriade

“…The main planning scale so far is the stand, where units are homogeneous regarding ecology, physiography and future developments. Some remarkable works are those by Aerstenet et al 2010;Anderson et al 2005;Crookston and Dixon, 2005;Ducheyne et al 2004;Huth et al 2005;Kolström and Lumatjärvi, 1999;Mathews et al 1999;Mette et al 2009;Torres-Rojo and Sanchez-Orois, 2005;Seely et al 2004;Snow and Lovatt, 2008;Twery et al, 2000 andVarma et al 2000. They have been applied in different areas such as Scandinavia, Australia, Austria, Canada, Malaysia, Scotland, Germany and Turkey for mixed stands of different species such as firs, spruces and tropical species among others.…”

PROLOG/RDBMS Integration in the NED Intelligent Information System

“…The NED project was conceived during meetings held in 1987 between members of the Northeastern Forest Experiment Station (now called the Northeastern Research Station) of the USDA Forest Service [Twery00,172]. A desire was expressed for a piece of software incorporating all of the growth and yield models designed at that station.…”

“…Particularly, a wish was voiced for "a single, easy-touse-program that could provide summary information and expert prescriptions for any forest type in the northeastern United States." [Twery00,172]. The name 'NED', an acronym for 'NorthEast Decision Model', was chosen [Twery00,168].…”

“…Integration is not a trivial problem; nevertheless, a unification of that sort is a primary goal of NED [Twery00,[186][187]189]. The NED project has resulted in the development of several software products, all of which are described in [Twery00].…”

“…As is usual for software in the forestry domain, it helps users manage for timber. It also, however, helps them manage their land from the standpoints of ecology, water quality, visual quality, and wildlife habitat [Twery00,168]. In this way, NED-1 and NED-2 fall into the category of software systems designed for ecosystem management, where such management is responsible for obtaining "a sensible middle ground between ensuring long-term protection of the environment while allowing an increasing population to use its natural resources for maintaining and improving human life" [Rauscher99].…”
