Compte rendu de trois ouvrages sur les rapports entre forêts, géographie historique et histoire de l'environnement dans le Nouveau Monde. 1: Americans and their forests. A historical geography by Michael Williams. 2: History of New Zealand forestry
by Michael Roche. 3: Australia's ever changing forests édité par Kevin J. Frawley and Noel M. Semple.
Les vallons de la NewForest sont décrits comme des creux perchés en amphithéâtre sur le bord des vallées, seuls ou en groupe sans chenal apparent. En dehors de la solifluxion, hypothèse d'une formation initiale due à la nivation. Les vallons sont
comparés aux combes crayeuses du sud de l'Angleterre et aux vallons européens. Une chronologie est proposée pour la NewForest.
Sheep grazing in national forest wilderness : a new look at an old fight
Environment ; Environmental management ; Forest ; Mountain ; Nature conservation ; Pastureland ; Sheep ; United States of America ; Wyoming
Review of the struggle between the livestock industry, environmentalists, and the US Forest Service to control how national forests and their resources are used. In the arid West forage, not the ragged forests of lodgpole pine, spruce, and fir, has
been the commodity harvested from the national forests. In the summer the ranchers in range states such as Wyoming rely heavily on these forests. A. reviews the situation in the bridger Wilderness. - (SLD)
Using examples from Cambodia, the Philippines and Papua New Guinea, the AA. examine the property negotiations underpinning the newforest carbon economy. They show that the institutions and land use negotiations needed to produce forest carbon
interact with existing property claims over land and forests. Claims to forest carbon are complicated by ambiguities and complexities surrounding rights to forested land. It creates an unstable basis for forest carbon markets and raises questions about

This paper describes the fire history of the Battell Research Forest (BRF), in Vermont, recorded by the age distributions of living and dead trees and by fire scars. The results illustrate a fire cycle that has controlled the recruitment
and mortality of most pine and probably most hemlock trees in this forest over the past 500 yr.
During the Spanish (1607-1820) and Mexican (1821-1846) periods, some 35 million acres in northern New Mexico were distributed to individuals and communities as land grants. Once the American era began in 1848, however, ownership of these areas fell
The basics of sustainable forest management in forest promotional complexes
Biodiversity ; Concept ; Dead wood ; Decision making process ; Ecosystem ; Environmental management ; Forest ; Forestry ; Sustainable development
The intent to create Forest Promotional Complex (FPC) was introducing a new quality to Polish forestry – by taking into account social preference for forests, by embracing local community needs, by compromising forest production with nature
protection and to introduce the rules of sustainable and balanced forest development. Main subject of this study is a dead wood and its ecological functions in managed forests and chosen FPC reserves. The problem of naturalization or ecologisation of forest

Composition structure and disturbance history of old-growth and second-growth forests in Adirondack Park, New York

The A. compares patterns of species composition, size structure, and disturbance in old-growth, hemlock-dominated forests with those characteristics of post-fire, second-growth forests in the Adirondack Mountains in northern New York to document
the persistence of historical events. The composition and structure of old growth were distinctive, but disturbance rates in old growth were similar to patterns in nearby second-growth forest in spite of differences in stand age and past human activity. Together
the old growth and the unmanaged secondary forests enhance landscape diversity.

La diversité paysagère a augmenté avec l'établissement surprenant post-incendie de trembles à des niveaux plus élevés (700-945 m) dans les High Peaks du Parc d'Adirondack dans l'Etat de New York.
The development of inventory activities in the field of forest damage assessment and monitoring during the last decade in Germany and the present state are recorded as far as remote sensing has been involved. Any forest inventory is influenced
by external factors, and the resulting difficulties for an introduction of new technologies are described. The following tasks and/or methods are discussed: global approaches to deforestation monitoring; working experience from local and regional case studies
Third World meets First World in the West Coast region of the South Island : possum hunting and the role of social forestry in indigenous forest management

The radical change in forest policy has profound implications for the West Coast, and an alternative to the conventional forest management framework is required which recognises the Government's desire to protect the indigenous forest cover, yet

The paper examines the impact of several synchronous disturbances, both natural and anthropogenic on the development of the Navajo ponderosa pine forest in the Chuska Mountains of the American Southwest during the fast several hundred years
. The specific objective is to determine the relative importance of historical factors, grazing, fire regime alteration, as well as climate fluctuations, in changing the forest pattern.
