Conservation Policy in Time and Space: Lessons from Divergent Approaches to Salvage Logging on Public Lands 7
Robinson, George; University at Albany, State University of New York; grobins@csc.albany.edu; Zappieri, Jeffrey; NYS Department of State, Division of Coastal Resources; jjamzip@superior.net.
A 50-yr precedent was reversed in 1995 when, following a powerful windstorm, salvage logging was disallowed in the protected Adirondack Park State Forest Preserve of New York, United States. Damage from a similar windstorm in 1950 had provoked massive salvage operations, approved by the New York State legislature on the grounds of fire prevention and resource conservation. Following the 1995 storm, state conservation officers and consulting ecologists were prepared with up-to-date assessment tools and a theoretical framework that treated large disturbances as normal ecosystem processes; the executive branch acted in accord with their recommendations to forgo salvage. Prior to these events in New York State, federal forest preserves in western states had...

Solanaceae composition, pollination and seed dispersal syndromes in Mexican mountain cloud forest 39
Albuquerque,Lidiamar Barbosa; Velázquez,Alejandro; Mayorga-Saucedo,Rafel.
In this work we hypothesised that Solanaceae species composition and pollination and seed dispersal syndromes change according to the degree of disturbance. Hence, the aim of this study is to analyze how the species composition of Solanaceae changes along disturbance gradients of mountain cloud forest, and to establish how Solanaceae pollination and seed dispersal syndromes vary along the same gradients. The study concentrates on the mountain cloud forests in Hidalgo, Mexico. Solanaceae species collection was carried out along transects, laid out alongside paths and secondary roads. Pollination and seed dispersal syndromes for all species were recorded based on floral and fruit morphological traits. From the 500 sample units surveyed, 392 contained 25...

Spatial patterns of tree community dynamics are detectable in a small (4 ha) and disturbed fragment of the Brazilian Atlantic forest 39
Machado,Evandro Luiz Mendonça; Oliveira-Filho,Ary Teixeira de.
The dynamics of the tree community of a fragment of tropical semideciduous forest was investigated in south-eastern Brazil. Surveys were carried out in 2000 and 2005 in 29 20 × 20 m plots. The main purpose was to assess the possibility of detecting spatial patterns of dynamics that could be related to the heterogeneity of both the environment and disturbance history in a small forest area (4.0 ha). Rates of mortality and recruitment of trees and gain and loss of basal area were obtained for the whole sample, four pre-defined soil habitats, diameter classes and twelve tree populations. The tree community was rather unstable in the period, once mortality rates surpassed recruitment rates and loss rates of basal area surpassed gain rates all-over the area...
