A phytosociological investigation was conducted in a virgin northern hardwood-spruce- fir forest in the lower elevations of the Bowl in the White Mountains of New Hampshire to determine the structure and dynamics of relatively small units of the forest. There is no evidence that the composition of the present forest has been influenced by human activity or fire, though portions of the present community demonstrate the effects of catastrophic damage caused by a severe hurricane in 1815. Forty-five 20- by 30-m plots ranging in elevation from 586 to 920 m were studied. Tree densities ranged from 685 to 3,851 stems/ha, basal areas from 22.0 to 60.5 m21ha, and shrub-seedling densities from 0.15 x 105 to 2.27 x 105 stems/ha. Bray and Curtis ordination was used to position the plots on the X and Y axes of a vegetational mosaic. The primary differentiating species were Picea rubens and Acer saccharum on the X axis and Betula alleghaniensis and Fagus grandifolia on the Y axis. The ordination was divided into seven subjectively defined plot clusters based primarily on the size-class distributions of four major tree species found in each plot. Cluster A represents a high-elevation, stable Picea abies unit. Cluster B represents a lower elevation, edaphically controlled Picea-Abies-Fagus grandifolia- Betula alleghaniensis unit which is projected to develop into a Picea-Abies-Fagus grandifolia unit. Clusters C to G represent stages in a successional sequence initiated by a catastrophic blowdown. The sequence is postulated to start with a Betula alleghaniansis Reproduction-Sapling unit, none of which was observed in the present forests of the Bowl. This stage develops into an All-Sized Immature Betula alleghaniensis unit (Cluster C) followed by a Mature Betula alleghaniensis/Sapling Acer saccharum-Fagus grandifolia unit (Cluster D). Then, depending on tree density, will follow a Mature Fagus grandifolia/Residual Decadent Betula alleghaniensis unit (Cluster E) or a Mixed Acer saccharum-Fagus grandifolia/Residual Decadent Betula alleghaniensis unit (Cluster F). Cluster F develops into a Decadent Acer saccharum-Fagus grandifolia unit (Cluster G). This and the unit represented by Cluster E could develop into a Hypothetical Decadent Fagus grandifolia/Acer saccharurn unit.

This volume represents a compilation of papers presented at the 3rd International Partners in Flight Workshop held October 1-5, 1995, at the Grand Hotel in Cape May, NJ. The title of the workshop was 'Partners in Flight Conservation Plan: Building Consensus for Action.' Manuscripts have been available on-line at the Cornell Laboratory of Ornithology web site (http://birds.cornell.edu/pifcapemay) since the year 1999, and the majority of them have been updated recently to reflect knowledge available by the 2000 publication date. The volume is divided into seven sections that range from general planning considerations to a case study in bird conservation planning. References from all papers are compiled in a single 'References' section at the end of the volume.

Mixedwoods forests occur in temperate forests around the world, providing unique ecological, economic, and cultural benefits, but there are key knowledge gaps on their natural dynamics and development pathways. In northeastern North America, records and studies show that red spruce was once a common component of northern hardwoods in this region; however, historic selective harvesting has greatly reduced the preponderance of these mixedwood ecosystems. Given the narrow regeneration niche of red spruce and the various anthropogenic and natural disturbances that have reduced this species, significant challenges exist to the restoration of red spruce-northern hardwoods mixedwoods. To address this challenge, our study characterized the structure and composition of two old-growth mixedwoods stands, Township 40 of Adirondack Park in New York and the Bowl Natural Area of White Mountain National Forest in New Hampshire.We used dendroecological data from large, stem-mapped plots to reconstruct the natural disturbance pathways of these forests to inform techniques for restoring and sustaining red spruce-northern hardwood forests into the future. At Township 40, red spruce was the second most abundant species, occupied 58.1% of the dominant and codominant crown classes, and had an importance value (IV) of 22.5%. At the Bowl, red spruce was the most abundant species, occupied 81.4% of the dominant and codominant crown classes, and had an IV of 37.3%. Large trees (stems [greater than or equal to]50 cm DBH) made up 30-33% of the basal area at each site and were predominantly comprised of yellow birch and red spruce. Red spruce dominated the sapling layer (stems 2.54-9.9 cm DBH) at both sites. Snags (standing dead trees) and coarse woody material (CWM) were also abundant, with Township 40 having 237 snags/ha and average CWM volume of 94.5 m3/ha and the Bowl containing 110 snags/ha and average CWM volume of 99.1 m3/ha. There was no evidence of stand-replacing disturbance at either site. The mean decadal rate of canopy loss at both sites was 6.3% with decadal canopy loss
