Identification of Abandoned Logging Roads in Point Reyes National Seashore

Post-Fire Vegetation Response in the Bishop Pine Forest at Point Reyes National Seashore

The eff ect of the 1995 fi re on the regeneration, composition and cover of the Bishop Pine (Pinus muricata) forest at Point Reyes National Seashore is examined. The human-caused fi re burned over 12,000 acres in and around the National Seashore engulfi ng most of the bishop pine forest along Inverness Ridge, where fi re intensity was the greatest. Bishop pine is a closed-cone pine that typical...

Salamander abundance along road edges and within abandoned logging roads in Appalachian forests.

Roads may be one of the most common disturbances in otherwise continuous forested habitat in the southern Appalachian Mountains. Despite their obvious presence on the landscape, there is limited data on the ecological effects along a road edge or the size of the "road-effect zone." We sampled salamanders at current and abandoned road sites within the Nantahala National Forest, North Carolina (U...

Valuing Beach Closures on the Padre Island National Seashore

In this paper we estimate the economic loss of hypothetical beach closures on the Padre Island National Seashore on the Gulf Coast of Texas. We use a travel cost random utility maximization (RUM) model with data from a random phone survey of Texas residents completed in 2001. We simulate realistic closures that may occur in event of an oil spill or other disruption. For comparison we valued the...

DirectX 11 Reyes Rendering

We map reyes-rendering to the GPU by leveraging new features of modern GPUs exposed by the Microsoft DirectX11 API. That is, we show how to accelerate reyes-quality rendering for realistic real-time graphics. In detail, we discuss the implementation of the split-and-dice phase via the Geometry Shader, including bounds on displacement mapping; micropolygon rendering without standard rasterizatio...
